    Full Text Available Anus neoplasm accounts for 2 to 4% of colorectal tumors, being more prevalent around the seventh and the eighth decades. Females are mostly affected, and the ratio is 3:1. Its increased prevalence amongst the population in the past years is probably related to the higher number of people that are affected by sexually transmitted diseases, mainly human papillomavirus (types 16 and 18, mostly and/or the human immunodeficiency virus. Diagnosis is based on clinical findings and anatomopathological tests. The treatment of choice is radiochemotherapy, and the rescue surgery with abdominoperineal resection is used for recurrence and persistence cases. A retrospective and prospective longitudinal observational study was performed with 11 patients diagnosed with anal neoplasm from 2004 to 2010. Six (54.5% were females and five (45.5% were males. The incidence was higher in the sixth decade, at the mean age of 54.45 years. The most frequent histological type observed was the epidermoid carcinoma, and the most frequent cell differentiation type was the moderately differentiated. Chemotharapy associated with radiotherapy was used in 81.9% of the patients, and abdominoperineal resection was necessary as a rescue surgery in 18.2% of the patients.Neoplasias do ânus correspondem de 2 a 4% dos tumores de intestino grosso, sendo predominante nas sétima e oitava décadas. A maior prevalência é em gênero feminino, com proporção de 3:1. O aumento da prevalência na população nos últimos anos provavelmente está relacionado ao número maior de pessoas com doenças sexualmente transmissíveis, principalmente o papilomavírus humano (tipos 16 e 18, mais comumente e/ou o vírus da imunodeficiência humana. O diagnóstico é feito a partir de achados clínicos somados ao exame anatomopatológico. O tratamento de escolha baseia-se na radioquimioterapia, sendo a cirurgia de resgate com amputação abdominoperineal utilizada para casos de recidiva ou persist

    Although childbirth is a well-known cause of coccydynia, this condition has not been studied previously. To explore the characteristics of postpartum coccydynia and identify risk factors. A case series study. A specialist coccydynia clinic in a department of physical medicine in a university hospital. A series of 57 women suffering from postpartum coccydynia was analyzed and compared with a control group of 192 women suffering from coccydynia due to other causes. Dynamic radiography enabled a comparison of the coccygeal mobility in the two groups. 7.3% of the cases of coccydynia in female patients seen in our clinic were related to childbirth. The pain appeared as soon as the patient adopted the sitting position after delivery. The deliveries had often been performed with instruments (forceps deliveries: 50.8%; vacuum-assisted deliveries: 7.0%) or were spontaneous but described as "difficult" (12.3%). Luxation of the coccyx was observed in 43.9% of the cases and 17.0% of the controls. Fracture of the coccyx was involved in 5.3% of the cases. A body mass index >27 and ≥2 vaginal deliveries were associated with a higher prevalence of luxation of the coccyx. Postpartum coccydynia is often associated with a difficult delivery, with the use of forceps in 50.8% of cases. Luxation and fracture of the coccyx are the two most characteristic lesions. Our results bring a better knowledge and should allow a better management of this specific etiology of coccydynia.

    Full Text Available Background: the study of salivary gland neoplasms is one of the most complex issues of cancer of the head and neck. Objective: to determine the behavior of tumors of the major salivary glands. Method: an observational-descriptive-retrospective case series in the Maxillofacial Surgery Department of the Hospital General Universitario Dr. Gustavo Lima Aldereguía of Cienfuegos, in the period from January 2000 through December 2009. Results: tumors of the major salivary glands occurred in the study population with a similarity between the sexes, with a slight predominance in males. The parotid gland was the most affected (93,55 %, pleomorphic adenoma was the most represented the benign tumor (58,06 %, while within the most frequent malignant adenocarcinoma (3,23 %. The most common surgical technique was subtotal parotidectomy. The (85,5 % of clinical diagnoses corresponded with histopathological and the type of tumor is found that of the 51 benign lesions (82,26 % are the largest percentage of agreement presented. In the present series were 61 patients (98,39 % alive without disease, only 1 patient (1,61 % had recurrence of their disease. We found no patient died during the study period. Conclusions: salivary gland tumors in the parotid gland predominate and are the most common benign tumors usually occur in adults.

    Full Text Available Introduction: Natural and unexpected death that happens within less than one hour of first symptom occurrence is called sudden death. Cardiovascular diseases are the main known reason of sudden death and more than 75% of sudden deaths in athletes are assigned to it. Here we reported the autopsy results of all cases with sudden death following exercise that were referred to forensic center of Tehran, Iran, from 2009 to 2014. Methods: In this cross sectional study all subjects who were registered to forensic medicine center of Tehran, Iran, from 2009 to 2014, as a case of sudden death following exercise were evaluated. Demographic data and medical history as well as autopsy and toxicology findings were retrospectively gathered using profiles of the deceased. Results were reported using descriptive analysis. Results: 14 cases were registered as sudden death following exercise in forensic medicine profiles during the study period. Exploring the files of the mentioned deceased, revealed five non-compatible cases in this regard. Finally, 9 eligible cases were enrolled (88.9% male. The mean age of the deceased was 28.66 ± 10.86 years (range: 7 – 40. Toxicological tests were available for 7 cases, one of which was positive for tramadol. Sudden death following football was reported most frequently (44.4%. Only 3 (33.3% cases had herald signs such as chest pain, syncope, or loss of consciousness. 1 case (11.11% had a positive history of sudden death in relatives. Conclusion: Although most sudden death victims are asymptomatic until the event, all those who suffer from symptoms such as chest pain, shortness of breath, dizziness, fatigue and irregular heart rate during physical activities, should be screened regarding common probable causes of sudden death.

    Non-organic lesions or diseases of unknown origin are sometimes misdiagnosed as "psychogenic" disorders or "psychosomatic" diseases. For the quality of life and safety of patients, recent attention has focused on diagnostic error. The aim of this study was to clarify the factors that affected misdiagnoses in psychosomatic medicine by examining typical cases and to explore strategies that reduce diagnostic errors. The study period was from January 2001 to August 2017. The data of patients who had visited the Department of Psychosomatic Medicine, Kindai University Hospital and its branches, Sakai Hospital and Nihonbashi Clinic, were collected. All patients were aged 16 years or over. Multiple factors, such as age, sex, presenting symptoms, initial diagnosis, final diagnosis, sources of re-diagnosis and types of diagnostic errors were retrospectively analyzed from the medical charts of 20 patients. Among them, four typical cases can be described as follows. Case 1; a 79-year-old woman, initially diagnosed with psychogenic vomiting due to depression that was changed to gastric torsion as the final diagnosis. Case 2; a 24-year-old man, diagnosed with an eating disorder that was later changed to esophageal achalasia. Case 10; a 60-year-old woman's diagnosis changed from conversion disorder to localized muscle atrophy. Case 19; a 68-year-old man, appetite loss from depression due to cancer changed to secondary adrenal insufficiency, isolated ACTH deficiency (IAD). This study showed that multiple factors related to misdiagnoses were combined and had a mutual influence. However, they can be summarized into two important clinical observations, diagnostic system-related problems and provider issues. Provider issues contain mainly cognitive biases such as Anchoring, Availability, Confirmation bias, Delayed diagnosis, and Representativeness. In order to avoid diagnostic errors, both a diagnostic system approach and the reduction of cognitive biases are needed. Psychosomatic

    1994-02-01

    Due to state planning requirements and federal landfill regulations, solid waste management in rural areas (particularly recycling) has received much attention in recent years. The growth of recycling during the 1980s occurred mainly in urban and suburban areas. Therefore, rural recycling is still a relatively new enterprise. This report presents several rural recycling case studies from Colorado, Illinois, Indiana, Iowa, Minnesota, Tennessee, and Ontario, Canada to provide examples of successes and problems. This report also discusses the current issues of cooperative marketing of recyclables and municipal solid waste flow control. With respect to recycling, a rural region does not have ready access to markets for collected materials and has difficulty in generating easily marketable quantities of recyclables.

  20. Case series and descriptive cohort studies in neurosurgery: the confusion and solution.

    Case series (CS) are well-known designs in contemporary use in neurosurgery but are sometimes used in contexts that are incompatible with their true meaning as defined by epidemiologists. This inconsistent, inappropriate and incorrect use, and mislabeling impairs the appropriate indexing and sorting of evidence. Using PubMed, we systematically identified published articles that had "case series" in the "title" in 15 top-ranked neurosurgical journals from January 2008 to December 2012. The abstracts and/or full articles were scanned to identify those with descriptions of the principal method as being "case series" and then classified as "true case series" or "non-case series" by two independent investigators with 100 % inter-rater agreement. Sixty-four articles had the label "case series" in their "titles." Based on the definition of "case series" and our appraisal of the articles using Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines, 18 articles (28.13 %) were true case series, while 46 (71.87 %) were mislabeled. Thirty-five articles (54.69 %) mistook retrospective (descriptive) cohorts for CS. CS are descriptive with an outcome-based sampling, while "descriptive cohorts" have an exposure-based sampling of patients, followed over time to assess outcome(s). A comparison group is not a defining feature of a cohort study and distinguishes descriptive from analytic cohorts. A distinction between a case report, case series, and descriptive cohorts is absolutely necessary to enable the appropriate indexing, sorting, and application of evidence. Researchers need better training in methods and terminology, and editors and reviewers should scrutinize more carefully manuscripts claiming to be "case series" studies.

    The respective roles of hypocalcemia and intracerebral calcifications in the occurrence of various neurological manifestations in hypoparathyroidism is not entirely clear. Nevertheless, therapeutic and prognostic implications are important. We analyze the neurological clinical aspects observed in hypoparathyroidism and correlate them to the biological calcium abnormality and radiological CT scan findings. We also compare these results with data reported in the idiopathic form of striatopallidodentate calcinosis. The neurological clinical, CT scan findings and outcome have been retrospectively studied in patients recruited during 13 years (2000-2012) for neurological features associated with hypoparathyroidism or pseudohypoparathyroidism. Twelve patients with primary hypoparathyroidism (n=5), secondary to thyroidectomy (n=4) and pseudohypoparathyroidism (n=3) were studied. The sex-ratio was 1 and mean age was 39 years. All patients had a tetany, 60% had epilepsy, associated in one patient with "benign" intracranial hypertension; 50% had behavioral changes. Response to calcium therapy was excellent for all these events. Moderate cognitive deficit was noted in three patients (25%), parkinsonism in two patients and hyperkinetic movement disorders in one other. These events were not responsive to calcium therapy and were more common in cases of extensive brain calcifications and in patients who had pseudohypoparathroidism. This study suggests that, in patients with hypoparathyroidism, epilepsy and psychiatric disorders are induced by hypocalcemia and reversible after its correction. Cognitive and extrapyramidal impairment seem to be related to the progressive extension of intracerebral calcification, particularly in patients with a late diagnosis. In patients with pseudohypoparathyroidism, this finding is different because of the contribution of other factors, specific to this disease. Copyright © 2013 Elsevier Masson SAS.

    2008-08-01

    The objective of this study was to report on the survival rate of 16 patients treated with extraoral implants in the auricular region, analyze treatment outcomes, and discuss important clinical variables encountered during treatment. Sixteen patients who received extraoral dental implants to retain auricular prostheses between 1987 and 2003 were followed retrospectively. The variables recorded were gender, initial diagnosis, number and size of implants, implant placement date, age at implant placement, history of radiation to the treated field, abutment size, design of initial prosthesis, age of initial prosthesis (when a remake was indicated), date of prosthesis delivery, soft tissue response, grafting procedure, date of last follow-up, and complications. All patients were thoroughly evaluated presurgically by the reconstruction team, which consisted of prosthodontists, a facial prosthetist, and an otolaryngologist. Surgical templates were used for all patients. The criteria for success of the prostheses included marginal accuracy, overall stability and function, symmetry/position, texture, color stability, and patient acceptance. Thirty-nine implants were placed in 16 patients. All 16 patients were completely satisfied with their reconstructions. No surgical complications, implant failures, or prosthetic failures were encountered. Therefore, the survival rate was 100%. Three patients (18.75%) had grade 0, seven (43.75%) had grade 1, five (31.25%) had grade 2, and one (6.25%) had grade 3 soft tissue inflammation. The inflammation completely resolved in 7 of the 13 patients (54%) with hygiene reinforcement or soft tissue reduction. The survival rate for bone-anchored titanium implants and prostheses was 100%. Bone-anchored titanium implants provided the 16 patients in this study with a safe, reliable, adhesive-free method to anchor auricular prostheses with recovery of normal appearance. Under the guidance of an appropriate implant team, proper positioning of

    Full Text Available Tattoo is going to be a very common practice especially among young people and we are witnessing a gradual increase of numerous potential complications to tattoo placement which are often seen by physicians, but generally unknown to the public. The most common skin reactions to tattoo include a transient acute inflammatory reaction due to trauma of the skin with needles and medical complications such as superficial and deep local infections, systemic infections, allergic contact dermatitis, photodermatitis, granulomatous and lichenoid reactions, and skin diseases localized on tattooed area (eczema, psoriasis, lichen, and morphea. In this series we present three cases of tattoo reaction.

    Antipsychotics increase the risk of stroke. Their effect on myocardial infarction remains uncertain because people prescribed and not prescribed antipsychotic drugs differ in their underlying vascular risk making between-person comparisons difficult to interpret. The aim of our study was to investigate this association using the self-controlled case series design that eliminates between-person confounding effects. All the patients with a first recorded myocardial infarction and prescription for an antipsychotic identified in the Clinical Practice Research Datalink linked to the Myocardial Ischaemia National Audit Project were selected for the self-controlled case series. The incidence ratio of myocardial infarction during risk periods following the initiation of antipsychotic use relative to unexposed periods was estimated within individuals. A classical case-control study was undertaken for comparative purposes comparing antipsychotic exposure among cases and matched controls. We identified 1546 exposed cases for the self-controlled case series and found evidence of an association during the first 30 days after the first prescription of an antipsychotic, for first-generation agents [incidence rate ratio (IRR) 2.82, 95% confidence interval (CI) 2.0-3.99] and second-generation agents (IRR: 2.5, 95% CI: 1.18-5.32). Similar results were found for the case-control study for new users of first- (OR: 3.19, 95% CI: 1.9-5.37) and second-generation agents (OR: 2.55, 95% CI: 0.93-7.01) within 30 days of their myocardial infarction. We found an increased risk of myocardial infarction in the period following the initiation of antipsychotics that was not attributable to differences between people prescribed and not prescribed antipsychotics. © The Author 2014.

    Post-marketing surveillance activities are particularly important for safety issues in children, the elderly, and patients with severe comorbidities since these populations are usually excluded from clinical trials. In addition, using electronic databases for monitoring of safety of marketed products has been of considerable interest. This study aimed to clarify the advantages and difficulties of the self-controlled case series method relative to cohort studies in pharmacoepidemiological studies in children, using an administrative database, and to explore the impact on results of handling the period eligible for analysis and recurrent events in different ways. Datasets of only individuals who had the outcome of interest were derived from an anonymized hospital administrative database in Japan from April 2003 through August 2011. We calculated incidence rate ratios (IRRs) and their 95 % confidence intervals (CIs) for the risks of diarrhea, bronchitis, and eczema related to palivizumab treatment in young children. The analysis included 'first diagnosed' events or 'multiple' events during an eligible period. An eligible period was defined in two ways: first-time inpatient periods of more than 3 continuous days (EPA); and a continuous period in cases where the interval between visits was below the 75th percentile of the interval between visits for patients with the same diagnosis (EPB). We extracted data for 70,771 patients and identified 641 who were exposed to palivizumab. The age-adjusted IRRs for diarrhea, bronchitis, and eczema were 3.0 (95 % CI 1.7-5.4), 10.3 (95 % CI 8.0-13.2), and 16.9 (95 % CI 12-23), respectively, in multiple events and the EPB eligible period. The IRRs varied greatly between the two eligible periods. This method could be a useful tool in pharmacoepidemiological studies in children. Careful consideration in the handling of inpatient and outpatient periods, including sensitivity analyses, is necessary because this method is a within

    In case-series or cohort studies, we propose a test of independence between the occurrences of two types of recurrent events (such as two repeated infections) related to an intermittent exposure (such as an antibiotic treatment). The test relies upon an extension of a recent method for analysing case-series data, in the presence of one type of recurrent event. The test statistic is derived from a bivariate Poisson generated-multinomial distribution. Simulations for checking the validity of the test concerning the type I error and the power properties are presented. The test is illustrated using data from a cohort on antibiotics bacterial resistance in schoolchildren. Copyright 2005 John Wiley & Sons, Ltd.

    Kleptomania is an enigmatic condition and is among the very few psychiatric disorders in which crime is medicalised and used as a legal defence. The scientific literature on kleptomania is scarce. Early literature and recent studies have shown a female preponderance, with an early age of onset of stealing in people with comorbid personality disorder(s). In a retrospective review of the case notes of theft offenders who had forensic psychiatric evaluations performed in a one-year period in 2010 at the Institute of Mental Health, Singapore, we found three patients who were diagnosed with kleptomania. In this report, we describe the pertinent clinical and sociodemographic characteristics, as well as the diagnostic issues of kleptomania in relation to the three cases.

    To study the pattern of presentation, course of disease and outcome of pregnancy in Peripartum Cardiomyopathy. A prospective study of sixteen cases of PPCM was conducted at Apple Saraswati Multispecialty Hospital and Dr. D.Y. Patil Medical College and Hospital, Kolhapur, Maharashtra, India from January 2006 to December 2012. Data included age distribution, parity, gestational age, symptoms and risk factors. Medical management and pregnancy outcome were documented. Serial echocardiography data was compiled for a period of one year. In our study 9/16 (56%) were primigravidae, 4/16 (25%) had pre-eclamsia and 6/16 (35%) had co-existing hypertension. The difference in Echocardiography parameters observed between recovered and non-recovered patients was significant: Left Ventricular End diastolic dimension (5.6 cm vs 6.06 cm), Left Ventricular Ejection Fraction (28.7% vs 22.4%) and Left Ventricular fractional shortening (17.5% vs 13.4%). Thirteen out of sixteen patients were followed up for a period of one year out of which 61% (8/13) patients recovered completely. There was one mortality. PPCM is a diagnosis of exclusion. Majority were young primigravidae presenting postnatally. Pre-eclampsia and hypertension were risk factors. ECHO parameters were reliable predictors of recovery. Future pregnancies are better avoided. Copyright © 2014 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.

    Full Text Available Considering perennial relation of the masses with concepts of determinism and free will, the intrinsic importance of these concepts in the area of religion, as well as regarding the ability of media in constructing the masses’ narrative of existence and also taking into account relations between religion, state and television in Iran, this study seeks to answer the question raised in the sample case study of a religious serial concerning representation of free will to its audiences. Hence, a brief introduction of the concept in Islamic thought and its implications has offered at first, to recognize the implied conflict between absolute determinism and absolute discretion in the practical part of this research. Adopting representational theory approach, we have used a combination of discourse analysis approaches and Greimas actantial model to analyze the serial dialogs about free will and underlying structure of activism, respectively. In this study we have shown that the series inspires deterministic-oriented discourse, by drawing actors’ charts of opening and final sequences as well as their schematic diagram. Type of narrative sequences and activity pattern also are deterministic, and the series is based on retributive nature of difficulties and reward-oriented character of pleasures. Two signifiers of fatalism and dreamful are attracted in its discourse area and influencing of social structures is rejected.

    Introduction Risk of mortality in the setting of acute kidney injury (AKI) in cats and dogs remains unclear. Objectives To evaluate the incidence of mortality in cats and dogs with AKI based on etiology (i.e. infectious versus non-infectious; receiving dialysis versus conservative treatment). Materials and methods Ovid Medline, EMBASE, and LILACS were searched up to July 2016. Articles were deemed eligible if they were case series studies evaluating the incidence of all-cause mortality in cats and dogs with AKI, regardless of etiology or the nature of treatment. Results Eighteen case series involving 1,201animalsproved eligible. The pooled proportions for overall mortality were: cats53.1% [95% CI 0.475, 0.586; I2 = 11,9%, p = 0.3352]; dogs 45.0% [95% CI 0.33, 0.58; I2 = 91.5%, P dogs, 19.2% [95% CI 0.134, 0.258; I2 = 37.7%, P = 0.0982]; AKI due non-infectious etiology for cats and dogs, 59.9% [95% CI 0.532, 0.663; I2 = 51.0%, P = 0.0211]. Conclusion Our findings suggest higher rates of overall mortality in cats and dogs with AKI due to non-infectious etiologies relative to infectious etiologies, and showed non-significant differences in terms of higher rates associated with dialysis compared to conservative management. Further investigations regarding optimal time to initiate dialysis and the development of clinical models to prognosticate the course of disease and guide optimal treatment initiation for less severe cases of AKI in cats and dogs is warranted.

    This study tested the effectiveness of schema therapy (ST) for patients with chronic depression. Twelve patients with a diagnosis of chronic depression participated. The treatment protocol consisted of 60 sessions, with the first 55 sessions offered weekly and the last five sessions on a biweekly basis. A single case series A-B-C design, with 6 months follow-up was used. Baseline (A) was a wait period of 8 weeks. Baseline was followed by introduction to ST and bonding to therapist (phase B) with individually tailored length of 12-16 sessions, after which further ST was provided (phase C) up to 60 sessions (included the sessions given as introduction). Patients were assessed with Hamilton Rating Scale for Depression three times during baseline, at the end of phase B, then every 12 weeks until the end of treatment and at 6 months follow-up. Secondary outcome measures were the Hamilton Rating Scale for Anxiety and the Young Schema Questionnaire. At the end of treatment 7 patients (approximately 60%) remitted or satisfactorily responded. The mean HRSD dropped from 21.07 during baseline to 9.40 at post-treatment and 10.75 at follow-up. The effects were large and the gains of treatment were maintained at 6-month follow-up. Only one patient dropped out for reasons not related to treatment. The lack of control group, the small sample and the lack of a multiple baseline case series. This preliminary study supports the use of ST as an effective treatment for chronic depression. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available 1 Abstract Background Many studies and meta-analyses have investigated the effects of statins on cancer incidence but without showing consistent effects. Methods A series of nested case-control studies was conducted covering 574 UK general practices within the QResearch database. Cases were patients with primary cancers diagnosed between 1998 and 2008. The associations between statin use and risk of ten site-specific cancers were estimated with conditional logistic regression adjusted for co-morbidities, smoking status, socio-economic status, and use of non-steroidal anti-inflammatory drugs, cyclo-oxygenase-2 inhibitors and aspirin. Results 88125 cases and 362254 matched controls were analysed. The adjusted odds ratio for any statin use and cancer at any site were 1.01 (95%CI 0.99 to 1.04. For haematological malignancies there was a significant reduced risk associated with any statin use (odds ratio 0.78, 95%CI 0.71 to 0.86. Prolonged (more than 4 years use of statins was associated with a significantly increased risk of colorectal cancer (odds ratio 1.23, 95%CI 1.10 to 1.38, bladder cancer (odds ratio 1.29, 95%CI 1.08 to 1.54 and lung cancer (odds ratio 1.18, 95%CI 1.05 to 1.34. There were no significant associations with any other cancers. Conclusion In this large population-based case-control study, prolonged use of statins was not associated with an increased risk of cancer at any of the most common sites except for colorectal cancer, bladder cancer and lung cancer, while there was a reduced risk of haematological malignancies.

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

    Full Text Available Tinea incognito is a dermatophytic infection which has lost its typical clinical appearance because of inappropriate use of topical or systemic corticosteroids. The clinical manifestations of tinea incognito can mimic many dermatoses such as eczema, psoriasis, allergic contact dermatitis, rosacea, seborrheic dermatitis and atopic dermatitis. The diagnosis of tinea incognito is confirmed by direct KOH (potassium hydroxide examination ( native preparation, making the fungal cultures from the lesion and histopathological examination in some cases. Systemic antifungal therapy is recommended in the treatment of tinea incognito. Herein, 10 cases of tinea incognito which mimicking various dermatoses were diagnosed and treated in our clinic in 2014 is presented.

    Full Text Available Abstract Background Home Based Management of fever (HBM was introduced as a national policy in Uganda to increase access to prompt presumptive treatment of malaria. Pre-packed Chloroquine/Fansidar combination is distributed free of charge to febrile children Methods A case-series study was performed during 20 weeks in a West-Ugandan sub-county with an under-five population of 3,600. Community drug distributors (DDs were visited fortnightly and recording forms collected. Referred children were located and primary caretaker interviewed in the household. Referral health facility records were studied for those stating having completed referral. Results Overall referral rate was 8% (117/1454. Fever was the main reason for mothers to seek DD care and for DDs to refer. Twenty-six of the 28 (93% "urgent referrals" accessed referral care but 8 (31% delayed >24 hours. Waiting for antimalarial drugs to finish caused most delays. Of 32 possible pneumonias only 16 (50% were urgently referred; most delayed ≥ 2 days before accessing referral care. Conclusion The HBM has high referral compliance and extends primary health care to the communities by maintaining linkages with formal health services. Referral non-completion was not a major issue but failure to recognise pneumonia symptoms and delays in referral care access for respiratory illnesses may pose hazards for children with acute respiratory infections. Extending HBM to also include pneumonia may increase prompt and effective care of the sick child in sub-Saharan Africa.

    2017-09-01

    To assess the safety and efficacy of a single intravesical injection of onabotulinumtoxinA (OnaBTA) for treating urge urinary incontinence (UUI) in women. We performed a prospective case-series study of consecutive patients with refractory UUI treated with an intravesical injection of OnaBTA. The patients were administered 100 units of OnaBTA injected into the bladder wall following 4 weeks of flushing with anticholinergic agents or beta 3 agonists. The urodynamic and clinical endpoints were evaluated before and 6 months after the injection of OnaBTA. The primary study endpoint was the number of episodes of urinary leakage. A total of 204 of the 210 selected patients conducted a valid visit 6 months after the therapeutic application. At 6 months of treatment with OnaBTA, 110 (53.9%) patients remained continent and were considered a success. However, 57 (27.9%) patients experienced one episode of urinary leakage per day, and 37 (18.2%) had 2 or more. In terms of the urodynamic parameters, we observed the following changes: increase in maximum bladder capacity (P<.0001) and reduced maximum pressure of the detrusor (P<.0001). In terms of the safety profile, 8 (3.9%) patients had self-limiting haematuria during the procedure, which resolved spontaneously, and 9 (4.4%) patients had acute urinary retention that required intermittent catheterisation. This study supports the use of OnabotulinumtoxinA in patients with urge urinary incontinence that does not respond to medical treatment. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U.

    2011-01-01

    Case series methodology involves the systematic assessment of a sample of related patients, with the goal of understanding how and why they differ from one another. This method has become increasingly important in cognitive neuropsychology, which has long been identified with single-subject research. We review case series studies dealing with impaired semantic memory, reading, and language production, and draw attention to the affinity of this methodology for testing theories that are expressed as computational models and for addressing questions about neuroanatomy. It is concluded that case series methods usefully complement single-subject techniques. PMID:21714756

    Objective  To compare initial brain computed tomography (CT) scans with follow-up CT scans at one year in children with congenital Zika syndrome, focusing on cerebral calcifications. Design  Case series study. Setting  Barão de Lucena Hospital, Pernambuco state, Brazil. Participants  37 children with probable or confirmed congenital Zika syndrome during the microcephaly outbreak in 2015 who underwent brain CT shortly after birth and at one year follow-up. Main outcome measure  Differences in cerebral calcification patterns between initial and follow-up scans. Results  37 children were evaluated. All presented cerebral calcifications on the initial scan, predominantly at cortical-white matter junction. At follow-up the calcifications had diminished in number, size, or density, or a combination in 34 of the children (92%, 95% confidence interval 79% to 97%), were no longer visible in one child, and remained unchanged in two children. No child showed an increase in calcifications. The calcifications at the cortical-white matter junction which were no longer visible at follow-up occurred predominately in the parietal and occipital lobes. These imaging changes were not associated with any clear clinical improvements. Conclusion  The detection of cerebral calcifications should not be considered a major criterion for late diagnosis of congenital Zika syndrome, nor should the absence of calcifications be used to exclude the diagnosis.

    Full Text Available Ameloblastic carcinoma is a rare odontogenic tumor exhibiting not only features of ameloblastoma but also features of carcinoma in either or both primary and metastatic lesions. Clinical features of this lesion are more aggressive and rapid than those of ameloblastoma. At times, it can metastasize to the lung or regional lymph nodes. Histologically, there is a picture of both ameloblastoma and carcinoma. Treatment is aggressive and has to be designed for each individual patient. English literature is sparse for this condition, as fewer cases have been reported till date. We report a series of four cases with different treatment modalities.

    Scimitar syndrome is a rare and complex congenital anomaly of the lung with multiple variables and is named for its resemblance to the classical radiological crooked sword. Its defining feature is the anomalous pulmonary drainage. It is associated with various cardiothoracic malformations and a wide spectrum of clinical manifestations. Nine patients diagnosed with scimitar syndrome found in the database of Hospital Infantil de México between 2009 and 2013 were reviewed. Demographic records, clinical status and hemodynamic parameters reported were collected. This case series called attention to certain differences between our group of patients and those reported in the international literature. Patients were predominantly female and were diagnosed between 1 and 20 months of life. All were asymptomatic at the time of the study. Half of the patients had a history of respiratory disease and all patients had with pulmonary hypertension. Surgical management was required in on-third of the patient group.

    Associations between atmospheric pressure and abdominal aortic aneurysm (AAA) rupture risk have been reported, but empirical evidence is inconclusive and largely derived from studies that did not account for possible nonlinearity, seasonality, and confounding by temperature. Associations between atmospheric pressure and AAA rupture risk were investigated using local meteorological data and a case series of 358 patients admitted to hospital for ruptured AAA during the study period, January 2002 to December 2012. Two analyses were performed-a time series analysis and a case-crossover study. Results from the 2 analyses were similar; neither the time series analysis nor the case-crossover study showed a significant association between atmospheric pressure ( P = .627 and P = .625, respectively, for mean daily atmospheric pressure) or atmospheric pressure variation ( P = .464 and P = .816, respectively, for 24-hour change in mean daily atmospheric pressure) and AAA rupture risk. This study failed to support claims that atmospheric pressure causally affects AAA rupture risk. In interpreting our results, one should be aware that the range of atmospheric pressure observed in this study is not representative of the atmospheric pressure to which patients with AAA may be exposed, for example, during air travel or travel to high altitudes in the mountains. Making firm claims regarding these conditions in relation to AAA rupture risk is difficult at best. Furthermore, despite the fact that we used one of the largest case series to date to investigate the effect of atmospheric pressure on AAA rupture risk, it is possible that this study is simply too small to demonstrate a causal link.

However, there is little epidemiological evidence of the association between APAP and acute kidney injury (AKI.Objectives: To examine the association between APAP and AKI using the self-controlled case series (SCCS method, which is a novel strategy to control between-person confounders by comparing the risk and reference periods in each patient.Methods: We performed SCCS in 1,871 patients (39.9% female who were administered APAP and subsequently developed AKI, by reviewing electronically stored hospital information system data from May 2011 to July 2016. We used conditional Poisson regression to compare each patient’s risk and reference period. As a time-varying confounder, we adjusted the status of liver and kidney functions, systemic inflammation, and exposure to NSAIDs.Results: We identified 5,650 AKI events during the 260,549 person-day observation period. The unadjusted incidences during the reference and exposure periods were 2.01/100 and 3.12/100 person-days, respectively. The incidence rate ratio adjusted with SCCS was 1.03 (95% confidence interval [CI]: 0.95–1.12.

    In the examination of the association between vaccines and rare adverse events after vaccination in postlicensure observational studies, it is challenging to define appropriate risk windows because prelicensure RCTs provide little insight on the timing of specific adverse events. Past vaccine safety studies have often used prespecified risk windows based on prior publications, biological understanding of the vaccine, and expert opinion. Recently, a data-driven approach was developed to identify appropriate risk windows for vaccine safety studies that use the self-controlled case series design. This approach employs both the maximum incidence rate ratio and the linear relation between the estimated incidence rate ratio and the inverse of average person time at risk, given a specified risk window. In this paper, we present a scan statistic that can identify appropriate risk windows in vaccine safety studies using the self-controlled case series design while taking into account the dependence of time intervals within an individual and while adjusting for time-varying covariates such as age and seasonality. This approach uses the maximum likelihood ratio test based on fixed-effects models, which has been used for analyzing data from self-controlled case series design in addition to conditional Poisson models.

    The fractal dimension is a significant geophysical parameter describing natural surfaces representing the distribution of the roughness over different spatial scale; in case of volcanic structures, it has been related to the specific nature of materials and to the effects of active geodynamic processes. In this work, we present the analysis of the temporal behavior of the fractal dimension estimates generated from multi-pass SAR images relevant to the Somma-Vesuvio volcanic complex (South Italy). To this aim, we consider a Cosmo-SkyMed data-set of 42 stripmap images acquired from ascending orbits between October 2009 and December 2012. Starting from these images, we generate a three-dimensional stack composed by the corresponding fractal maps (ordered according to the acquisition dates), after a proper co-registration. The time-series of the pixel-by-pixel estimated fractal dimension values show that, over invariant natural areas, the fractal dimension values do not reveal significant changes; on the contrary, over urban areas, it correctly assumes values outside the natural surfaces fractality range and show strong fluctuations. As a final result of our analysis, we generate a fractal map that includes only the areas where the fractal dimension is considered reliable and stable (i.e., whose standard deviation computed over the time series is reasonably small). The so-obtained fractal dimension map is then used to identify areas that are homogeneous from a fractal viewpoint. Indeed, the analysis of this map reveals the presence of two distinctive landscape units corresponding to the Mt. Vesuvio and Gran Cono. The comparison with the (simplified) geological map clearly shows the presence in these two areas of volcanic products of different age. The presented fractal dimension map analysis demonstrates the ability to get a figure about the evolution degree of the monitored volcanic edifice and can be profitably extended in the future to other volcanic systems with

    The PROCESS guideline was developed in 2016 through expert Delphi consensus. It aimed to improve the quality of reporting of surgical case series. This study assessed the impact of the introduction of the PROCESS guideline on reporting for surgical case series submitted to three journals. 20 case series published in the International Journal of Surgery Case Reports (IJSCR), the International Journal of Surgery (IJS) or the Annals of Medicine and Surgery (AMS) in September to December 2016, prior to the introduction of the PROCESS guideline (the pre-PROCESS period), were randomly identified and scored against the PROCESS criteria. Two authors independently scored each article a total score out of 29, the 'PROCESS score' (expressed as a percentage). Scores for the two researchers were compared and consensus was reached to achieve a final score set. The process was repeated for the January 2017 to April 2017 issues of the three journals, post PROCESS implementation (the post-PROCESS period). The mean PROCESS score was 80% (range 66-90%) for the pre-PROCESS period and 84% (range 72-95%) for the post-PROCESS period, a 4% relative increase [STATS]. The Cohen's Kappa score between researchers was 0.907 implying very substantial agreement. Implementation of the PROCESS guideline resulted in a 5% improvement in the reporting quality of surgical case series published in three journals. Further research is needed to identify and successfully navigate existing barriers to greater compliance. Authors, reviewers and editors should adhere to the guidelines to boost reporting quality. Journals should develop their policies and guide for authors to incorporate the guideline and mandate compliance. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

    2016-11-01

    Full Text Available Current time series clustering algorithms fail to effectively mine clustering distribution characteristics of time series data without sufficient prior knowledge. Furthermore, these algorithms fail to simultaneously consider the spatial attributes, non-spatial time series attribute values, and non-spatial time series attribute trends. This paper proposes an adaptive density-based time series clustering (DTSC algorithm that simultaneously considers the three above-mentioned attributes to relieve these limitations. In this algorithm, the Delaunay triangulation is first utilized in combination with particle swarm optimization (PSO to adaptively obtain objects with similar spatial attributes. An improved density-based clustering strategy is then adopted to detect clusters with similar non-spatial time series attribute values and time series attribute trends. The effectiveness and efficiency of the DTSC algorithm are validated by experiments on simulated datasets and real applications. The results indicate that the proposed DTSC algorithm effectively detects time series clusters with arbitrary shapes and similar attributes and densities while considering noises.

    The current work examined a consecutive series of patients presenting vascular malformations (VMs) and venous lakes (VLs) of the lip and oral mucosa who were treated with transmucosal diode laser applications and assessed over a 1 year period. Fifty-nine patients (31 males and 28 females) presenting low-flow VMs or VLs of the oral cavity were treated transmucosally using a diode laser (with an 830 nm operating wavelength and 1.6 W output power) with a 320 µm diameter flexible fiber. All the lesions were assessed 7 days, 30 days, and 1 year after the laser treatment, and the lesion reduction percentage was scored on a one to five scale. The patients were also asked to assess their pain perception daily during the 7 days following the treatment using a visual analog scale (VAS). There were no procedure-related intra- or post-operative complications; only modest pain intensity was reported. Thirty days after the treatment, lesion reduction was described as excellent or good in 52 cases; it was fair or poor in 7. Six patients (F:M ratio 2:4) required a second diode laser application. At the 1 year follow-up, volume reduction was complete in 48 out of 59 patients; there were five recurrences (F:M ratio 3:2). No relevant gender-related differences were noted. The use of diode laser application to treat small oral VMs and VLs was associated to shorter operating times and fewer postoperative complications with respect to the scapel surgery approach. More than one session may nevertheless be required if the anomaly is larger than 10 mm. Lasers Surg. Med. 50:111-116, 2018. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Study design labels are used to identify relevant literature to address specific clinical and research questions and to aid in evaluating the evidentiary value of research. Evidence from the human healthcare literature indicates that the label "case series" may be used inconsistently and inappropriately. Our primary objective was to determine the proportion of studies in the canine and feline veterinary literature labeled as case series that actually corresponded to descriptive cohort studies, population-based cohort studies, or other study designs. Our secondary objective was to identify the proportion of case series in which potentially inappropriate inferential statements were made. Descriptive evaluation of published literature. One-hundred published studies (from 19 journals) labeled as case series. Studies were identified by a structured literature search, with random selection of 100 studies from the relevant citations. Two reviewers independently characterized each study, with disagreements resolved by consensus. Of the 100 studies, 16 were case series. The remaining studies were descriptive cohort studies (35), population-based cohort studies (36), or other observational or experimental study designs (13). Almost half (48.8%) of the case series or descriptive cohort studies, with no control group and no formal statistical analysis, included inferential statements about the efficacy of treatment or statistical significance of potential risk factors. Authors, peer-reviewers, and editors should carefully consider the design elements of a study to accurately identify and label the study design. Doing so will facilitate an understanding of the evidentiary value of the results. Copyright © 2017 The Authors.

    Blonanserin is a relatively new atypical antipsychotic drug, and has been used in Korea and Japan for 1 and 3 years, respectively. Therefore, the clinical characteristics of blonanserin remain unclear. In this study, to clarify the features of blonanserin, we performed prospective and long-term comparative investigations of patients treated with blonanserin. We followed 10 psychiatric patients who were switched to blonanserin from other antipsychotics for 1 year (schizophrenia: 8; mental retardation: 2). In the light of quality of life, we focused on adverse effects of patients during the follow-up. In the long-term follow-up, (i) hyperprolactinemia is more frequently in risperidone than in blonanserin; however, it is more often in blonanserin than in olanzapine; and (ii) weight gain is more common in olanzapine than in blonanserin. We switched to blonanserin from other antipsychotic drugs within the same case, and then followed the case for 1 year. We consider that long-term observations within the same case lead to obvious comparisons among drugs. On the basis of our findings, we conclude that blonanserin may be useful for the maintenance treatment of schizophrenia without inducing hyperprolactinemia and weight gain.

    Dengue fever (DF) is a climate-sensitive disease that has been emerging in southern regions of Taiwan over the past few decades, causing a significant health burden to affected areas. This study aims to propose a predictive model to implement an early warning system so as to enhance dengue surveillance and control in Tainan, Taiwan. The Seasonal Autoregressive Integrated Moving Average (SARIMA) model was used herein to forecast dengue cases. Temporal correlation between dengue incidences and climate variables were examined by Pearson correlation analysis and Cross-correlation tests in order to identify key determinants to be included as predictors. The dengue surveillance data between 2000 and 2009, as well as their respective climate variables were then used as inputs for the model. We validated the model by forecasting the number of dengue cases expected to occur each week between January 1, 2010 and December 31, 2015. In addition, we analyzed historical dengue trends and found that 25 cases occurring in one week was a trigger point that often led to a dengue outbreak. This threshold point was combined with the season-based framework put forth by the World Health Organization to create a more accurate epidemic threshold for a Tainan-specific warning system. A Seasonal ARIMA model with the general form: (1,0,5)(1,1,1)52 is identified as the most appropriate model based on lowest AIC, and was proven significant in the prediction of observed dengue cases. Based on the correlation coefficient, Lag-11 maximum 1-hr rainfall (r=0.319, Pdengue surveillance and control in Tainan, Taiwan. We conclude that this timely dengue early warning system will enable public health services to allocate limited resources more effectively, and public health officials to adjust dengue emergency response plans to their maximum capabilities.

    Malaria is the most contagious global concern. As a public health problem with outbreaks, affect the quality of life and economy, also could lead to death. Therefore, this research is to forecast malaria cases with climatic factors as predictors in Mandailing Natal Regency. The total number of positive malaria cases on January 2008 to December 2016 were taken from health department of Mandailing Natal Regency. Climates data such as rainfall, humidity, and temperature were taken from Center of Statistic Department of Mandailing Natal Regency. E-views ver. 9 is used to analyze this study. Autoregressive integrated average, ARIMA (0,1,1) (1,0,0)12 is the best model to explain the 67,2% variability data in time series study. Rainfall (P value = 0.0005), temperature (P value = 0,0029) and humidity (P value = 0.0001) are significant predictors for malaria transmission. Seasonal adjusted factor (SAF) in November and March shows peak for malaria cases.

    The purpose of this study was to present early and adult cases of anterior open bite that were treated efficiently using different treatment approaches and mechanics. Five patients of different age groups (from 7 to 27 years), suffering from a clear Anterior open bite deformity, were properly diagnosed and relevant treatment modality for each was selected. Positive overbite was efficiently achieved for all patients. Patient compliance is a key factor in using removable habit breakers. However, fixed palatal crib gave the same results but in shorter time. Anterior open bite of skeletal components should be thoroughly evaluated before selecting camouflage or orthognathic surgery treatment modality.

  7. Uranium-series comminution ages of continental sediments: Case study of a Pleistocene alluvial fan

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Victoria E.; DePaolo, Donald J.; Christensen, John N.

    2010-04-30

    Obtaining quantitative information about the timescales associated with sediment transport, storage, and deposition in continental settings is important but challenging. The uranium-series comminution age method potentially provides a universal approach for direct dating of Quaternary detrital sediments, and can also provide estimates of the sediment transport and storage timescales. (The word"comminution" means"to reduce to powder," reflecting the start of the comminution age clock as reduction of lithic parent material below a critical grain size threshold of ~;;50 mu m.) To test the comminution age method as a means to date continental sediments, we applied the method to drill-core samples of the glacially-derived Kings River Fan alluvial deposits in central California. Sediments from the 45 m core have independently-estimated depositional ages of up to ~;;800 ka, based on paleomagnetism and correlations to nearby dated sediments. We characterized sequentially-leached core samples (both bulk sediment and grain size separates) for U, Nd, and Sr isotopes, grain size, surface texture, and mineralogy. In accordance with the comminution age model, where 234U is partially lost from small sediment grains due to alpha recoil, we found that (234U/238U) activity ratios generally decrease with age, depth, and specific surface area, with depletions of up to 9percent relative to radioactive equilibrium. The resulting calculated comminution ages are reasonable, although they do not exactly match age estimates from previous studies and also depend on assumptions about 234U loss rates. The results indicate that the method may be a significant addition to the sparse set of available tools for dating detrital continental sediments, following further refinement. Improving the accuracy of the method requires more advanced models or measurements for both the recoil loss factor fa and weathering effects. We discuss several independent methods for obtaining fa on individual samples

    The study aims at a better definition of continuous spike-waves during sleep (CSWS) with an early thalamic lesion, focusing on various grades of sleep-potentiated epileptiform activity (SPEA). Their possible relationship with different clinical features was studied to try to define prognostic factors of the epileptic disorder, especially relating to behavior/cognitive outcome, in order to improve prevention and treatment strategies. Sixty patients with early thalamic injury were followed since the first registration of SPEA with serial neurological, long term EEG monitoring and neuropsychological examinations, as well as neuroimaging and a detailed clinical history. They were classified in three different groups according to the sleep spike-waves (SW) quantification: electrical status epilepticus during sleep (ESES), more than 85% of slow sleep; overactivation between 50% and 85% and simple activation between 10 and 50%). Results were then examined also with a statistical analysis. In our series of CSWS occurring in early brain injured children with unilateral thalamic involvement there is a common neuropathologic origin but with various grades of SPEA severity. Statistical analysis showed that patients evolving toward ESES presented more commonly the involvement of the mediodorsal part of thalamus nuclei and a bilateral cortico-subcortical brain injury, epilepsy was more severe with a delayed onset; moreover, in the acute stage .ESES patients presented the worst behavior/cognitive performances. As to cognitive and behavior outcome, longer SPEA duration as well as bilateral brain injury and cognitive/behavior impairment in acute phase appear linked to a poor outcome; some particular neuropathology (ischemic stroke and haemorrhagic infarction) as well as hydrocephalus shunting are associated with behavior disorders. Discrete features seem to support different underlying mechanisms in ESES patients in comparison with less severe SPEA; they represent negative

    Full Text Available Background and Objectives. A new two-step hysteroscopic myomectomy carried out in the office setting and without anesthesia was feasible for the excision of submucous myomas. The objective of this study was to assess whether removal of submucous myomas from the uterine cavity after hysteroscopic laser enucleation is necessary. Methods. Between June 2009 and April 2013, all outpatients with symptomatic myomatosis (bleeding, pelvic pain, and infertility assessed ultrasonographically were eligible to participate in a prospective study. All patients underwent office hysteroscopic enucleation of submucous myomas. Enucleated myomas were left in the uterine cavity. Neither anesthesia nor antibiotic prophylaxis was used. Results. Sixty-one women (mean age: 47.3 years were included. Regardless of hysteroscopic localization and grading, all myomas were enucleated. The mean (standard deviation, SD diameter of the myoma as measured by the ultrasound scan was 22.6 (8.5 mm. In 29 cases (47.5%, the diameter of the resected myoma was >20 mm and in 10 cases (16.4% >30 mm. After a mean follow-up of 68.2 (16.5 days, none of the patients showed a residual myoma inside the uterine cavity. Conclusions. The present results indicate that leaving laser-enucleated submucous myoma in the uterine cavity is a feasible and safe therapeutic option.

    Full Text Available Currently, the best practice to support land planning calls for the development of Spatial Data Infrastructures (SDI capable of integrating both geospatial datasets and time series information from multiple sources, e.g., multitemporal satellite data and Volunteered Geographic Information (VGI. This paper describes an original OGC standard interoperable SDI architecture and a geospatial data and metadata workflow for creating and managing multisource heterogeneous geospatial datasets and time series, and discusses it in the framework of the Space4Agri project study case developed to support the agricultural sector in Lombardy region, Northern Italy. The main novel contributions go beyond the application domain for which the SDI has been developed and are the following: the ingestion within an a-centric SDI, potentially distributed in several nodes on the Internet to support scalability, of products derived by processing remote sensing images, authoritative data, georeferenced in-situ measurements and voluntary information (VGI created by farmers and agronomists using an original Smart App; the workflow automation for publishing sets and time series of heterogeneous multisource geospatial data and relative web services; and, finally, the project geoportal, that can ease the analysis of the geospatial datasets and time series by providing complex intelligent spatio-temporal query and answering facilities.

    To study by flow cytometry (FCM) the ploidy and the cellular cycle of nodular hidradenoma (NH) and hidradenocarcinoma (HC) and to assess the prognostic utility of this technique in such tumors. We studied retrospectively 2 HC and 11 NH one of which was considered as an atypical NH. Monoparametric study by FCM was realized on paraffin-embedded material. The extracted cells were marked by Propidium's lodure and cellular cycle was analyzed by the software Mod-Fit LT. Our study showed eleven 100% diploid profiles, 10 of which had low S-phase varying between 2 and 12%. All of these 11 tumors were NH. S-phase was high (23.79%) in a single case that corresponded to the atypical NH. Two tumors showed aneuploid profiles; these corresponded to the 2 HC. The results of the cytometric study suit perfectly to those of the histopathologic examination. FCM could so help to establish the prognosis of these tumors. But further studies are necessary to determine the value of this technique.

    To compare the total fluoroscopy time (FT) based on the fluoroscopy mode used-continuous vs. pulsed-in patients who underwent percutaneous nephrolithotomy (PCNL). The study cohort evaluated 111 patients who underwent PCNL by a single surgeon. Standard (continuous) fluoroscopy of 30 frames per second (fps) was used in the first 56 cases (SF group), while the next 55 consecutive cases were performed under pulsed fluoroscopy of two fps (PF group). The presence of surgeon's previous experience decreased the possible impact of the learning curve on the outcome. In both groups, using ultrasound in combination to fluoroscopy performed the renal access. The stone complexity was determined using Guy's stone score (GSS). Complications were evaluated using Clavien-Dindo classification. Median FT was significantly lower in PF group (76.8 s) compared to SF group (155.4 s) (p fluoroscopy leads to significantly lower radiation exposure comparing to the use of continuous fluoroscopy. This advantage does not compromise the safety and efficacy of the procedure.

    The variables collected by a sensor network constitute a heterogeneous data source that needs to be properly organized in order to be used in research and geophysical monitoring. With the time series term we refer to a set of observations of a given phenomenon acquired sequentially in time. When the time intervals are equally spaced one speaks of period or sampling frequency. Our work describes in detail a possible methodology for storage and management of time series using a specific data structure. We designed a framework, hereinafter called TSDSystem (Time Series Database System), in order to acquire time series from different data sources and standardize them within a relational database. The operation of standardization provides the ability to perform operations, such as query and visualization, of many measures synchronizing them using a common time scale. The proposed architecture follows a multiple layer paradigm (Loaders layer, Database layer and Business Logic layer). Each layer is specialized in performing particular operations for the reorganization and archiving of data from different sources such as ASCII, Excel, ODBC (Open DataBase Connectivity), file accessible from the Internet (web pages, XML). In particular, the loader layer performs a security check of the working status of each running software through an heartbeat system, in order to automate the discovery of acquisition issues and other warning conditions. Although our system has to manage huge amounts of data, performance is guaranteed by using a smart partitioning table strategy, that keeps balanced the percentage of data stored in each database table. TSDSystem also contains modules for the visualization of acquired data, that provide the possibility to query different time series on a specified time range, or follow the realtime signal acquisition, according to a data access policy from the users.

    Full Text Available Abstract Background Overactivity of anterior and/or posterior tibial tendon may be a causative factor of spastic varus foot deformity. The prevalence of their dysfunction has been reported with not well defined results. Although gait analysis and dynamic electromyography provide useful information for the assessment of the patients, they are not available in every hospital. The purpose of the current study is to identify the causative muscle producing the deformity and apply the most suitable technique for its correction. Methods We retrospectively evaluated 48 consecutive ambulant patients (52 feet with spastic paralysis due to cerebral palsy. The average age at the time of the operation was 12,4 yrs (9-18 and the mean follow-up 7,8 yrs (4-14. Eigtheen feet presented equinus hind foot deformity due to gastrocnemius and soleus shortening. According to the deformity, the feet were divided in two groups (Group I with forefoot and midfoot inversion and Group II with hindfoot varus. The deformities were flexible in all cases in both groups. Split anterior tibial tendon transfer (SPLATT was performed in Group I (11 feet, while split posterior tibial tendon transfer (SPOTT was performed in Group II (38 feet. In 3 feet both procedures were performed. Achilles tendon sliding lengthening (Hoke procedure was done in 18 feet either preoperatively or concomitantly with the index procedure. Results The results in Group I, were rated according to Hoffer's clinical criteria as excellent in 8 feet and satisfactory in 3, while in Group II according to Kling's clinical criteria were rated as excellent in 20 feet, good in 14 and poor in 4. The feet with poor results presented residual varus deformity due to intraoperative technical errors. Conclusion Overactivity of the anterior tibial tendon produces inversion most prominent in the forefoot and midfoot and similarly overactivity of the posterior tibial tendon produces hindfoot varus. The deformity can be

    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.

    AIM: To evaluate endometrioma located at cesarean scatrix. METHODS: Medical data of 6 patients who presented to our institution with abdominal wall endometrioma were evaluated retrospectively and reviewed literature in this case series. The diagnostic approaches and treatment is discussed. RESULTS: All patients had a painful mass located at abdominal scars with history of cesarean section. The ages ranged from 31 to 34 and Doppler ultrasonography (US) detected hypoechoic mass with a mean diameter of 30 mm. Initial diagnosis was endometrioma in 4 and incisional hernia in 2 of 6 patients. Treatment was achieved with surgical excision in 5 patients, and one is followed by hormone suppression therapy with gonadotropin. CONCLUSION: Malignant or benign tumors of abdominal wall and incisional hernias should be kept in mind for diagnosis of endometrioma. Imaging methods like doppler US, computed tomography and magnetic resonance imaging should be used for differential diagnosis. Definitive diagnosis can only be made histopathologically. The treatment should be complete surgical excision and take care against intraoperative auto-inoculation of endometrial tissue in order to prevent recurrences. PMID:24868512

    Impulsivity is a psychological phenomenon that has not been extensively studied in headache patients. We aim to assess the presence of impulsivity in patients with chronic migraine (CM) and medication overuse (MO). All patients examined in an outpatient headache clinic between January 2013 and March 2014 were included. Episodic migraine, CM, and MO were diagnosed according to ICHD-III beta criteria. We prospectively gathered demographic and clinical characteristics. Mood disorders were evaluated using the Hospital Anxiety and Depression Scale (HADS) and impulsiveness was assessed with the Plutchik impulsivity scale. A total of 155 patients were included (22 men, 133 women). The mean age (SD) was 38.2 (11.7) years (range, 18-70); 104 patients (67.1%) presented CM and, among them, 74 (71.1%) had MO. Of the patient total, 28.4% met criteria for anxiety, 7.1% for depression and 16.1% for impulsivity. The CM group showed higher scores for HADS-anxiety (8.5 [SD 4.5] vs. 6.4 [SD 3.6], p=0.003) and HADS-depression (4.4 [4.3] vs. 1.9 [2.3], p<0.001). Among CM cases only, scores for HADS-anxiety (9.3 [4.4] vs. 6.8 [4.3], p=0.01) and HADS-Depression (5.1 [4.6] vs. 2.7 [2.9], p=0.002) were higher in patients who also had MO. We found no associations between Plutchik scale scores or presence of impulsivity with either CM or MO. Impulsivity is a common trait in our population of migraine patients, but unlike mood disorders, it is not correlated with either CM or MO. Copyright © 2014 Sociedad Española de Neurología.

    In this article, the use of time series of satellite imagery to flood hazard mapping and flood risk assessment is presented. Flooded areas are extracted from satellite images for the flood-prone territory, and a maximum flood extent image for each flood event is produced. These maps are further fused to determine relative frequency of inundation (RFI). The study shows that RFI values and relative water depth exhibit the same probabilistic distribution, which is confirmed by Kolmogorov-Smirnov test. The produced RFI map can be used as a flood hazard map, especially in cases when flood modeling is complicated by lack of available data and high uncertainties. The derived RFI map is further used for flood risk assessment. Efficiency of the presented approach is demonstrated for the Katima Mulilo region (Namibia). A time series of Landsat-5/7 satellite images acquired from 1989 to 2012 is processed to derive RFI map using the presented approach. The following direct damage categories are considered in the study for flood risk assessment: dwelling units, roads, health facilities, and schools. The produced flood risk map shows that the risk is distributed uniformly all over the region. The cities and villages with the highest risk are identified. The proposed approach has minimum data requirements, and RFI maps can be generated rapidly to assist rescuers and decisionmakers in case of emergencies. On the other hand, limitations include: strong dependence on the available data sets, and limitations in simulations with extrapolated water depth values. © 2013 Society for Risk Analysis.

    GNSS Zenith Total Delay (ZTD) data is useful for numerical weather forecasting and climate analysis. Considering the fact that tropospheric delays over the mountainous areas are the most difficult to be modelled, we explored the influence of different troposphere models in Precise Point Positioning (PPP) mode. We used GPS data from 2008 to 2014 at 28 permanent EUPOS (European Position Determination System) stations, including 9 EPN (EUREF Permanent Network) ones, located in the Sudeten and Carpathians. The GPS data was processed in PPP mode using Bernese 5.2 GNSS software with the final IGS (International GNSS Service) orbits and clocks. Different processing variants were tested implying the newest mapping functions (Global Mapping Function - GMF, and Vienna Mapping Function - VMF1) as well as different time resolutions and constraints on estimated parameters (ZTD and gradients). Median trends and amplitudes of annual/semi-annual oscillations for ZTD series were determined with Weighted Least Squares Estimation (WLSE) obtaining 0.1±0.5 mm/year and 44.7 / 7.2 ± 5 mm, respectively. Power Spectral Densities (PSDs) were estimated using Lomb-Scargle method for each of individual variants. PSDs showed, except oscillations of year and half a year, many other significant peaks in ZTD time series at higher frequencies, about 60, 30, 24, 20, 15, 12, 10, 8, 7, 6, 5, 4 and 3 cpy. The proper subtraction of the periodicities is crucial, because they will make stochastic part appear to be artificially autocorrelated. In order to recognized the periodicities in the ZTD signal, we analyzed the ZTD differences between GPS-derived delays and ERA-Interim reanalysis. The results of analysis showed the significant change from station to station and between variants. According to these results the authors will indicate an optimal processing strategy concerning troposphere modelling.

    Histoplasmosis is an invasive mycosis caused by inhalation of the spores of dimorphic fungi Histoplasma capsulatum. The disease manifests in the lung as acute or chronic pulmonary histoplasmosis and in severe cases gets disseminated in multiple organs like skin, adrenal gland, central nervous system, lymph node, liver, spleen, bone marrow, and gastrointestinal tract. It occurs most commonly in immunodeficient patients like HIV-positive patients and transplant recipients, while immunocompetent hosts are affected rarely. In cases of gastrointestinal histoplasmosis, the samples are collected for culture and biopsy should be sent for histopathological examination for definitive diagnosis. We conducted a retrospective study of colonic biopsies performed in the department of gastroenterology in a tertiary care hospital of north India from January 2014 to December 2015. Five cases of colonic histoplasmosis were diagnosed on histopathology out of which 4 patients were from north India while 1 patient was from Myanmar. The patients presented with various complaints, including loose stools, diarrhea, altered bowel habits, and gastrointestinal bleeding. The prognosis is very good after early and aggressive treatment while the disease is fatal if it remains untreated. In our study, 2 patients died within few days of diagnosis due to delay in the diagnosis, dissemination, and associated complications. Other patients were started on amphotericin B deoxycholate and are under follow-up. An early diagnosis of gastrointestinal histoplasmosis is important as appropriate treatment leads to long-term survival while untreated cases are almost fatal.

    Objective To investigate the association between use of bisphosphonates estimated from prescription information and risk of gastrointestinal cancers. Design Series of nested case-control studies. Setting General practices in the United Kingdom contributing to the QResearch primary care database (660) and the Clinical Practice Research Datalink (CPRD) (643). Participants Patients aged ≥50 with a diagnosis of a primary gastrointestinal cancer in 1997-2011, each matched with up to five controls by age, sex, practice, and calendar year. Main outcome measures Odds ratios for incident gastrointestinal cancers (colorectal, oesophageal, gastric) and use of bisphosphonates, adjusted for smoking status, ethnicity, comorbidities, and use of other drugs. Results 20 106 and 19 035 cases of colorectal cancer cases, 5364 and 5135 cases of oesophageal cancer cases, and 3155 and 3157 cases of gastric cancer were identified from QResearch and CPRD, respectively. Overall bisphosphonate use (at least one prescription) was not associated with risk of colorectal, oesophageal, or gastric cancers in either database. Adjusted odds ratios (95% confidence interval) for QResearch and CPRD were 0.97 (0.79 to 1.18) and 1.18 (0.97 to 1.43) for oesophageal cancer; 1.12 (0.87 to 1.44) and 0.79 (0.62 to 1.01) for gastric cancer; and 1.03 (0.94 to 1.14) and 1.10 (1.00 to 1.22) for colorectal cancer. Additional analyses showed no difference between types of bisphosphonate for risk of oesophageal and colorectal cancers. For gastric cancer, alendronate use was associated with an increased risk (1.47, 1.11 to 1.95; P=0.008), but only in data from the QResearch database and without any association with duration and with no definitive confirmation from sensitivity analysis. Conclusions In this series of population based case-control studies in two large primary care databases, exposure to bisphosphonates was not associated with an increased risk of common gastrointestinal cancers.

    Black blood magnetic resonance imaging (MRI)is a promising imaging tool in predicting aneurysm rupture. Could it be also valuable in evaluating the treatment effect of endovascular and conservative treated aneurysms? Two patients were treated with stent and coil and one with Aspirine (ASS). Correlation of treatment response and contrast enhancement of the aneurysm wall is examined. In the first case stenting failed to treat the aneurysm and contrast enhancement in the wall did never subside during follow up black blood MRI. In the second case the aneurysm responded well to stenting and decreased in size, which was correlating significantly with attenuation of contrast enhancement in black blood MRI. In the third case the aneurysm responded to ASS treatment by decreasing in size as shown in follow up MR-angiography and the contrast enhancement in its wall decreased after 8 months of therapy. Black blood MRI seems to be a promising tool not only in predicting aneurysms at risk of rupture, but also in observing treatment responses after endovascular procedures or even Aspirine administration. When contrast enhancement decreases, aneurysm treatment seems to be successful as can be shown in decreasing size in the follow up angiography. PMID:29619161

    Detrimental effects of women's negative feelings during pregnancy have been extensively examined and documented, but research on the influence of positive feelings and protective factors on their prenatal mental health is scarce. Evidence from the positive psychology field has shown that practicing some brief positive exercises, called positive psychology interventions, can maximize well-being by increasing positive emotions, engagement, and meaning. The aim of this study is to examine the effect of a positive psychology web-based intervention on indices of women's prenatal well-being. Specifically, a case series design was adopted, and data from six women are presented. Participants were involved in a 5-week online positive psychology intervention that includes a set of positive psychology interventions specifically adapted for pregnant women. Measures of women's mental well-being, depression, pregnancy-related anxiety, life satisfaction, and social support were measured at pre- and post-intervention. Compliance with the intervention and exercise preferences were assessed at post-test. Single-item related well-being measures were assessed weekly. The findings of this case series study indicate potential effects of the intervention on supporting mental well-being and decreasing depressive symptomatology in these pregnant women. Furthermore, this study provides some suggestions for developing future online-based positive interventions addressed to pregnant women. However, these findings are preliminary, and future studies are needed in order to assess the effects of the intervention in a wider population of pregnant women.

    Cystic cervical hygroma or cervical cystic lymphangioma is a congenital benign disease of the lymphatic system that is characterized by the accumulation of lymph in the jugular lymphatic sacs of the nuchal region. The factor that causes this pathology is not clarified yet but the physiopathological mechanism seems to be multifactorial. The incidence and prevalence of cervical hygroma are increased in patients with Turner syndrome, Down syndrome, Klinefelter syndrome, Edwards syndrome, Patau syndrome, Noonan syndrome, pterygium syndrome, Cantrell pentalogy, Fryns syndrome, Apert syndrome, Pena-Shokeir syndrome and achondroplasia. The gold standard method in establishing the antenatal diagnosis is ultrasonography, a non-invasive and low-cost procedure. We report four cases of fetuses who were diagnosed antepartum with cervical hygroma in the Department of Obstetrics and Gynecology of the University Emergency Hospital in Bucharest, Romania. Two products of conception were send to the Department of Anatomy of the "Carol Davila" University of Medicine and Pharmacy, Bucharest, for an extensive morphological analysis. Cervical cystic hygroma is a congenital condition of variable expression in terms of both morphology and chronology. A complete ultrasound examination, performed by an experimented specialist in maternal-fetal medicine is essential in establishing the diagnosis of cervical hygroma. Screening for aneuploidies, between the 11th and 14th weeks of pregnancy is also mandatory due to the frequent association between cervical hygroma and congenital anomalies.

    Background To assess and compare survival rates of immediately and delayed loaded short implants (7 mm) in free ends of a partially edentulous jaw with moderate-severe alveolar bone resorption. Material and Methods 24 patients with atrophic edentulous free-ends were included in this prospective study. Four study groups were monitored monthly and their behavior was evaluated: bridges supported only by short implants and mixed short and long implant bridge groups, both with immediate and delayed loading. Failures, bone loss, probing depth and bleeding on probing were evaluated. Results 54 Mk III Shorty TiU and 15 Brånemark System®MK III TiU implants with a length longer than 7mm were included in the study. Twenty-eight implants were inserted following the immediate loading protocol and 26 according a two-stage procedure, depending on the torque value. The cumulative survival rate of short implants was 87% (n=54) after a mean time of 47.72 months (range 33-62 months), showing statistically significant differences related to loading protocol (p=0.047). Short implants immediately loaded had a higher long-term survival rate (96.4%) compared to the other study group (76.9%). Besides, short implants splinted to longer immediately loaded implants presented the highest survival rate (100%). Twenty-five (53.19%) short implants showed a bone loss of less than one millimeter after the follow-up period. Statistically significant differences were found between bleeding on probing, presence of plaque or suppuration and a higher bone loss in both loading protocols (p=0.001). Conclusions Immediate loading of short implants placed on free ends can be considered an option in the treatment protocol of patients with severe bone resorption especially if implants are splinted to others of greater length.

    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.

    Full Text Available Erectile dysfunction is an important problem for men and their families which has an organic cause in about 50 percent of cases. When there is a vasculogenic etiology for this defect, radiologic assessment is unavoidable. Cavernosometry and Cavernosography are ultimate procedures for diagnosis of venous leakage. There is no reliable data about this defects in Iran. The objective of this study was to determine the rate of venous leakage in patients with erectile dysfunction by Pharmarco-Cavernosometry and Cavernosography. In this case series study, 100 patient with erectile dysfunction who referred to radiologic ward in Sina hospital was selected and Pharmarco-Cavernosometry and Cavernosography were conducted for them. In Cavernosometry, after injection of Prostaglandin E1 and salin normal infusion into corpus covernosum, the pressure was determined. In cavernosography, diluted omnipaque was injected and venous leakage and other defects were recognized. Myoclinic's criteria was use for analysis of the results. Mean age of patients was 35.6±11.6. Most of the cases were in 20 to 40 age group. The frequency of venous leakage based on 50 mmHg reduction in pressure (from 150 mmHg, after 30 seconds discountinuance of normal salin infusion was 90 percent. This figure based on the ratio of Maintenance Flow Rate to Induced Flow Rate, was more than 92 percent. The frequency of venous leakage according to Cavernosography was 89 percent. There was no significant side effects in any of cases induced by procedures. The results of study, shows the high prevalence of venous leakage in patients referring for erectile dysfunction.

    Suicidal behaviour in delusional disorder (DD) has been poorly studied. This study aimed to describe the prevalence of clinically significant depression, suicidal ideation and behaviour in these patients, and to relate them with psychotic or depressive symptoms. A cross-sectional study including 44 outpatients with DD (DSM-IV-TR) was conducted. Demographic and clinical data, as well as scores in clinical assessment scales: Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance Scale, Hamilton Depression Rating Scale (17-item version) and Columbia Suicide Severity Rating Scale, were recorded. The sample was divided into 2 groups according to presence or absence of comorbid depression (CD). Fifteen patients (34.1%) had CD, 14 (31.8%) suicidal ideation and 7 (15.9%) suicidal behaviour in the previous 2 years. Patients with CD had an earlier age at onset and for a first psychiatric appointment, and had higher scores on the PANSS general subscale (p=0,043) and in intensity of suicidal ideation (p=0,001). In our sample, patients with DD and CD have more frequently suicidal ideation and behaviour than those without CD. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    2016-03-03

    Inducible urticaria is a heterogeneous group of skin disorders characterized by the appearance of wheals, pruritus and/or angioedema, sometimes accompanied by systemic symptoms caused by innocuous stimuli (cold, heat, pressure, etc.). This group of disorders compromises people's quality of life and most of the literature in this regard comes from case reports and case series since its epidemiology has been poorly studied and some cases are very rare. The aim of this review is to show an up-to-date overview of the available literature for various types of inducible urticarias, always beginning with an illustrative case and then describing their pathophysiological mechanisms, clinical manifestations, and treatment.

    Coccygodynia is a pain of the coccyx that is typically exaggerated by pressure. Management includes anti-inflammatory medications, physiotherapy, and coccyx manipulation. Coccygectomy is the surgical approach for treating coccygodynia when the conservative management fails. Generally, coccygectomy yields good results. Its most common complication is wound infection. To determine the effectiveness of coccygectomy in patients with coccygodynia. A retrospective review of 70 patients (52 females and 18 males) with coccygodynia at King Khalid University Hospital in Riyadh was carried out, and the outcomes were studied. Twenty patients did not respond to conservative management; therefore, bimanual coccyx manipulation was done. Eleven were identified with instability and did not respond to coccygeal manipulation. Coccygectomy was performed on 8 patients while 3 declined. All patients who underwent coccygectomy showed improvement of their symptoms. One case of superficial wound infection and delayed wound healing was encountered. Coccygectomy provides effective pain relief to patients not responding to conservative therapies.

    To examine the effects of the Intensive Dysphagia Rehabilitation approach on physiological and functional swallowing outcomes in adults with neurogenic dysphagia. Intervention study; before-after trial with 4-week follow-up through an online survey. Outpatient university clinics. A consecutive sample of subjects (N=10) recruited from outpatient university clinics. All subjects were diagnosed with adult-onset neurologic injury or disease. Dysphagia diagnosis was confirmed through clinical and endoscopic swallowing evaluations. No subjects withdrew from the study. Participants completed the 4-week Intensive Dysphagia Rehabilitation protocol, including 2 oropharyngeal exercise regimens, a targeted swallowing routine using salient stimuli, and caregiver participation. Treatment included hourly sessions twice per week and home practice for approximately 45 min/d. Outcome measures assessed pre- and posttreatment included airway safety using an 8-point Penetration Aspiration Scale, lingual isometric pressures, self-reported swallowing-related quality of life (QOL), and level of oral intake. Also, patients were monitored for adverse dysphagia-related effects. QOL and adverse effects were also assessed at the 4-week follow-up (online survey). The Intensive Dysphagia Rehabilitation approach was effective in improving maximum and mean Penetration Aspiration Scale scores (PDysphagia Rehabilitation approach was safe and improved physiological and some functional swallowing outcomes in our sample; however, further investigation is needed before it can be widely applied.

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

    Meniscal subluxation results in the natural history of knee osteoarthritis (OA). Periarticular infiltration should minimize possible complications related to penetration of corticosteroids into the joint space in the treatment of knee OA.According to pain relief and improvement of function, the aim of this study is to evaluate the effectiveness of perimeniscal corticosteroid ultrasound guided injection in knee OA. Thirty-two patients received an injection of 0.5 ml of methylprednisolone-acetate around perimeniscal tissues. Outcome measures were pain relief and knee function, assessed by Visual Analogue Scale (VAS) [24, 29, 30] measured at rest (VAS-R) and during stairs climbing (VAS-C) and by Italian-Western Ontario and McMaster Universities (WOMAC) scale. Clinical evaluation was performed at baseline, at 1 and 4 weeks of follow-up. Mean baseline values of VAS-R and VAS-C were 6.79 ± 1.17 and 7.6 ± 1.39, respectively. All subjects showed a significant reduction in pain over time (p 0.05). Corticosteroid perimeniscal ultrasound guided injection can be considered as an adjunct to core treatment for the relief of moderate to severe pain in people with knee OA. IV.

    Full Text Available Background: Increasing antimicrobial resistance is now a critical point of human being in the world. Especially wide spectrum antibiotics resistance germs like vancomycin-resistant enterococci (VRE should be dealt as soon as possible as an emergency conflict. Our study tries to reveal the amount of irrational use of vancomycin in a teaching hospital in Iran.Methods: We elected the whole inpatients that received vancomycin between February 2007 and May 2008.Results: Forty four out of those 45 patients had inappropriate indication and dosing regimen of vancomycin (97.7%. The most use of vancomycin was recorded in hematology – oncology ward and then Intensive Care Unit (ICU. Culture responses were negative despite great clinical evidence of infection.Conclusion: Vancomycin irrational use was high compared to other countries and it could be concerned as a major health problem by health policy makers and physicians to deal. However more detailed researches are needed to reveal the other aspects of this problem. Implementation of antibiotic protocols and standard treatment guidelines are recommended.

    Objectives To study the pattern of presentation, course of disease and outcome of pregnancy in Peripartum Cardiomyopathy. Methods A prospective study of sixteen cases of PPCM was conducted at Apple Saraswati Multispecialty Hospital and Dr. D.Y. Patil Medical College and Hospital, Kolhapur, Maharashtra, India from January 2006 to December 2012. Data included age distribution, parity, gestational age, symptoms and risk factors. Medical management and pregnancy outcome were documented. Serial echocardiography data was compiled for a period of one year. Results In our study 9/16 (56%) were primigravidae, 4/16 (25%) had pre-eclamsia and 6/16 (35%) had co-existing hypertension. The difference in Echocardiography parameters observed between recovered and non-recovered patients was significant: Left Ventricular End diastolic dimension (5.6 cm vs 6.06 cm), Left Ventricular Ejection Fraction (28.7% vs 22.4%) and Left Ventricular fractional shortening (17.5% vs 13.4%). Thirteen out of sixteen patients were followed up for a period of one year out of which 61% (8/13) patients recovered completely. There was one mortality. Conclusion PPCM is a diagnosis of exclusion. Majority were young primigravidae presenting postnatally. Pre-eclampsia and hypertension were risk factors. ECHO parameters were reliable predictors of recovery. Future pregnancies are better avoided. PMID:24814122

    The aim of this study was to measure titanium (Ti) content in human jawbones and to show that Ti was released from dental implants inserted into these jawbones. Seven samples from four human subjects with dental implants were analysed as test group and six bone samples of similar topographical regions from six human subjects without implants served as control. The contents of various elements in human jawbones were detected by inductively coupled plasma optical emission spectrometry. The distributions of various isotopes in human mandibular bone were measured with laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Histological analyses of undecalcified, Giemsa-Eosin stained mandible sections were performed by light microscopy and particles were identified in human bone marrow by scanning electron microscope-energy dispersive X-ray analysis. In test group only Ti content was significantly higher compared to control group. The mean contents of Ti were 1940μg/kg in test group and 634μg/kg in control group. The highest Ti content detected in human mandibular bone was 37,700μg/kg-bone weight. In samples 4-7 (human subjects II-IV), increased Ti intensity was also detected by LA-ICP-MS in human mandibular tissues at a distance of 556-1587μm from implants, and the intensity increased with decreasing distance from implants. Particles with sizes of 0.5-40μm were found in human jawbone marrow tissues at distances of 60-700μm from implants in samples 4-7. Ti released from dental implants can be detected in human mandibular bone and bone marrow tissues, and the distribution of Ti in human bone was related to the distance to the implant.

    To compare the immunohistochemistry (IHC) expression of epidermal growth factor receptor (EGFR) in oral squamous cell carcinomas (OSCC) with the gene amplification evaluated by fluorescence in situ hybridization (FISH) and chromogenic in situ hybridization (CISH) and their association with clinicopathological parameters. Additionally, we tested the sensibility and specificity of CISH in comparison with FISH. Case series study Oral surgery and pathology department in a school of dentistry. 52 patients with histopathological diagnosis of OSCC. Tumour tissue samples from 52 patients with OSCC were evaluated by IHC, FISH and CISH using tissue microarray technology. Clinicopathological data from all patients were collected. EGFR+ rates were 53.8% (28/52) by IHC, 5.8% (3/52) by CISH and 15.4% (8/52) by FISH. Amplification detected by CISH and FISH with IHC negative occurred in 3.8% (2/52), and one case (1.9%) showed amplification detected by CISH and FISH and protein overexpression concomitantly. There were 9.6% FISH+ cases with IHC and CISH negative rates and 6/8 (75%) FISH+ and also EGFR+ cases; however, an association between protein expression and gene amplification was not found for both techniques. IHC and FISH rates were not associated with clinicopathological features. CISH+ rates were associated with T3-T4 status. Compared with FISH assay, CISH reached a sensitivity of 37.5% and specificity of 100%. There is no association between EGFR expression and gene amplification in OSCC when the IHC is driven to external epitopes of the protein. Although CISH demonstrates specificity, technical problems may influence sensibility when compared with FISH.

    Penetrating spinal cord injuries (SCIs) are an uncommon injury and not reported very frequently. SCIs cause sensory, motor and genitourinary system problems or a combination of sensorimotor dysfunctions. These are among the most debilitating kinds of disorders and negatively affect quality of life, not only for the patient, but also for their family members. Therefore, the present study aims to evaluate complete or incomplete SCIs and the course of the injury and the prognosis for SCIs caused by stab wounds. This case-series design study was performed on 57 patients attending the emergency department of Taleqani Trauma Center (Kermanshah, Iran) due to SCIs caused by violent encounters involving sharp objects such as a knife, dagger, whittle and Bowie-knife between 1999 and 2011. An assessment of sensory and motor functions was performed as part of the neurological examination on admission, and during the treatment, using the Frankel Classification grading system, and the results were recorded. The average age of patients was 27 years (SD= 7.9, Range=17 to 46 years). The results of the study showed a proportion of cervical, thoracic and lumbar injuries of 23 (40%), 24 (42%) and 10 (18%), respectively. There was no case of cerebrospinal fluid leakage (CSF) or infection at the wound site in the subjects. Regarding the extent of the SCI, the combined neurological assessment showed that several patients (43%) had a complete SCI with no sensory and motor functions in the sacral segments and the segments below the site of injury. In 32 patients (57%) incomplete injuries were observed; i.e. they showed only some degrees of sensory-motor functions that were below the neurological level. Both complete and incomplete SCIs are of great importance because the prognosis of SCI is directly associated with the location and extent of injury. It should be considered that partial recovery from SCIs is possible in few cases of complete injuries. Therefore, all the patients should be

    Nodding Syndrome (NS), previously called Nodding Disease, is a chronic and debilitating illness affecting thousands of children aged 3-18 years in post-conflict Northern Uganda and South Sudan. Characterised by malnutrition, stunted growth, mental retardation and seizures, some researchers have designated it as epilepsy. With reports appearing in Northern Uganda in1997, NS reached epidemic proportions around 2000-2003 when people were moved into Internally Displaced People's (IDP) camps. Investigations for infections (onchocerciasis) and toxins have been inconclusive as to cause, treatment or outcome. No study has addressed the possible relationship of NS to childhood war-trauma experiences. To explore a possible relationship of exposure to prolonged war-trauma and the emergence of epidemic NS in Northern Uganda. This study was a case-series descriptive psychiatric naturalistic field observations of NS cases from homesteads in Northern Uganda and psychiatric investigations and treatment of NS cases referred to Mulago National Referral and Teaching Hospital. Detailed Psychiatric clinical evaluations and field observations revealed that NS children had been exposed to severe war-related psychological and physical trauma as well as non-specific CNS insults including untreated CNS infections/infestations and malnutrition possibly causing seizures. Many children suffered post-traumatic stress disorder (PTSD) and depression. NS could present as an association of childhood complex PTSD, (called Developmental Trauma Disorder), occurring in the chronically war-traumatised children of Northern Uganda, complicated by severe prolonged depression with its characteristic symptoms of psychomotor retardation, anxiety, anhedonia and anorexia. This, coupled with food shortages, resulted in malnutrition, wasting and stunted growth with severe avitaminoses. Many children had seizures. All this calls for multi-disciplinary treatment approaches.

    Primary pulmonary and mediastinal synovial sarcoma is rare and poses a diagnostic challenge particularly when unusual histological features are present. We present 60 cases of primary pulmonary and mediastinal synovial sarcoma (29 male and 27 female subjects; mean age, 42 years) and compare our results with five prior series to better define unusual histological features. Clinically, patients with mediastinal synovial sarcoma were younger with a male gender bias. Radiologically, tumors were well delineated with distinctive magnetic resonance imaging features and little vascular enhancement. In all, 21/46 patients died of disease within 5 years. Histologically, all tumors had dense cellularity, interlacing fascicles, hyalinized stroma, and mast cell influx. Hemangiopericytoma-like vasculature (48/60), focal myxoid change (30/60), and entrapped pneumocytes (23/60) were seen. Calcification was not prevalent (10/60). Unusual histological features included Verocay body-like formations (7/60), vague rosettes (6/60), well-formed papillary structures (3/60), adenomatoid change (3/60), and rhabdoid morphology (2/60). Immunohistochemistry demonstrated expression of pancytokeratin (39/58), epithelial membrane antigen (29/53), cytokeratin 7 (26/40), cytokeratin 5/6 (5/7), calretinin (15/23), CD99 (19/23), bcl-2 (24/24), CD56 (11/11), S-100 (9/51), and smooth muscle actin (8/32). In total, 92% (36/39) of primary pulmonary and mediastinal synovial sarcomas studied were positive for t(x;18). In conclusion, our study confirms the clinical, histological, immunohistochemical, and molecular data from previous large series of primary pulmonary and mediastinal synovial sarcoma. Compared with soft tissue synovial sarcoma, primary pulmonary and mediastinal synovial sarcoma has less calcification, less obvious mast cell influx, and less radiologic vascularity, but similar magnetic resonance imaging features, percentage of poorly differentiated tumors, and number of t(x;18)-positive tumors

    As communities' fears of Ebola virus disease (EVD) in West Africa exacerbate and their trust in healthcare providers diminishes, EVD has the potential to reverse the recent progress made in promoting facility-based delivery. Using retrospective data from a study focused on maternal and newborn health, this analysis examined the influence of EVD on the use of facility-based maternity care in Bong Country, Liberia, which shares a boarder with Sierra Leone - near the epicenter of the outbreak. Using a case series design, retrospective data from logbooks were collected at 12 study sites in one county. These data were then analyzed to determine women's use of facility-based maternity care between January 2012 and October 2014. The primary outcome was the number of facility-based deliveries over time. The first suspected case of EVD in Bong County was reported on June 30, 2014. Heat maps were generated and the number of deliveries was normalized to the average number of deliveries during the full 12 months before the EVD outbreak (March 2013 - February 2014). Prior to the EVD outbreak, facility-based deliveries steadily increased in Bong County reaching an all-time high of over 500 per month at study sites in the first half of 2014 - indicating Liberia was making inroads in normalizing institutional maternal healthcare. However, as reports of EVD escalated, facility-based deliveries decreased to a low of 113 in August 2014. Ebola virus disease has negatively impacted the use of facility-based maternity services, placing childbearing women at increased risk for morbidity and death.

    The objective of this study is to determine in a case series (four patients) how calcified deposits in renal papillae are associated with the development of calcium oxalate monohydrate (COM) papillary calculi. From the recently collected papillary calculi, we evaluated retrospectively patients, subjected to retrograde ureteroscopy, with COM papillary lithiasis. The COM papillary calculi were found to result from subepithelial injury. Many of these lesions underwent calcification by hydroxyapatite (HAP), with calculus morphology and the amount of HAP in the concave zone dependent on the location of the calcified injury. Most of these HAP deposits grew, eroding the epithelium covering the renal papillae, coming into contact with urine and starting the development of COM calculi. Subepithelial HAP plaques may alter the epithelium covering the papillae, resulting in the deposit of COM crystals directly onto the epithelium. Tissue calcification depends on a pre-existing injury, the continuation of this process is due to modulators and/or crystallization inhibitors deficiency. Since calculus morphology and the amount of detected HAP are dependent on the location and widespread of calcified injury, all types of papillary COM calculi can be found in the same patient. All patients had subepithelial calcifications, with fewer papillary calculi, demonstrating that some subepithelial calcifications did not further evolve and were reabsorbed. A high number of subepithelial calcifications increases the likelihood that some will be transformed into COM papillary calculi.

    Currently, there is no satisfactory treatment for Raynaud's phenomenon (RP) in systemic sclerosis (SSc). Recently, it has been reported that botulinum toxin A (BTX-A) injection was effective for the treatment of RP in SSc patients. The objective was to assess the efficacy and safety of BTX-A on RP in Japanese SSc patients. In the prospective, case series study, 10 Japanese SSc patients with RP received 10 U of BTX-A injections into the hand. The change in severity of RP, including the frequency of attacks/pain, color changes, duration time of RP and the severity of pain, was assessed by Raynaud's score and pain visual analog scale (VAS) at each visit during 16 weeks. The recovery of skin temperature 20 min after cold water stimulation was examined by thermography at baseline and 4 weeks after injection. The number of digital ulcers (DU) and adverse effects were assessed at each visit. BTX-A injection decreased Raynaud's score and pain VAS from 2 weeks after injection, and the suppressive effect was continued until 16 weeks after injection. Skin temperature recovery after cold water stimulation at 4 weeks after injection was significantly enhanced compared with that before injection. All DU in five patients were healed within 12 weeks after injection. Neither systemic nor local adverse effects were observed in all cases. We conclude that BTX-A injection significantly improved the activity of RP in SSc patients without any adverse events, suggesting that BTX-A may have possible long-term preventive and therapeutic potentials for RP in Japanese SSc patients. © 2015 Japanese Dermatological Association.

    Adults with coeliac disease (CD) often report persistent fatigue, even when CD appears well controlled for unknown reasons. To evaluate common indications for testosterone panel (TP) testing and prevalence of low testosterone (T) in CD. In our case series, we determined common indications for checking TP in CD. Next, we conducted a case-control study to compare TP in CD vs. healthy controls (HC). We compared mean total T (TT), free T (FT) based on serologic, histologic disease activity. Finally, we assessed TT in tissue transglutaminase (tTG)+ vs. tTG- subjects and CD vs. HC obtained from the National Health and Nutrition Examination Survey (NHANES). 53 coeliac males had TP tested. Common indications included osteoporosis and fatigue. Low FT was observed in 7/13 men with osteoporosis and 5/6 with fatigue. In our case-control study (n=26 each), there was no difference in mean TT or FT between CD vs. HC, tTG+ vs tTG- or Marsh 0 vs. Marsh 3 groups. NHANES data showed no difference in mean TT between tTG+ vs tTG- (n=16 each) or CD vs. HC subjects (n=5 each). Low T occurs in CD patients at a similar rate as the general population. Common presentations of low T may mimic non-responsive CD symptoms. Copyright © 2016 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

    More than a century ago, Ortner described a case of cardiovocal syndrome wherein he attributed a case of left vocal fold immobility to compression of the recurrent laryngeal nerve by a dilated left atrium in a patient with mitral valve stenosis. Since then, the term Ortner's syndrome has come to encompass any nonmalignant, cardiac, intrathoracic process that results in embarrassment of either recurrent laryngeal nerve-usually by stretching, pulling, or compression; and causes vocal fold paralysis. Not surprisingly, the left recurrent laryngeal nerve, with its longer course around the aortic arch, is more frequently involved than the right nerve, which passes around the subclavian artery. To discuss the pathogenesis of hoarseness resulting from cardiovascular disorders involving the recurrent laryngeal nerve along with the findings of literature review. This paper reports a series of four cases of Ortner's syndrome occurring due to different causes. Case study. Ortner's syndrome could be a cause of hoarseness of voice in patients with cardiovascular diseases. Although hoarseness of voice is frequently encountered in the Otolaryngology outpatient department, cardiovascular- related hoarseness is an unusual presentation. Indirect laryngoscopy should be routinely performed in all cases of heart disease.

Seven hundred and thirty-four patients were delivered at home (50.2%) and 1010 were less than 7 days old (69%). Out of the total cohort of expired subjects, 89 participants (74.8%) were < 7 days of life. Mortality was more in neonates born at home in rural areas to illiterate mother; 74 patients (62.2%). Most of the deaths; 57 were in neonates suffering from specific infections (47.9%) followed by 38 deaths in immaturity group (31.9%) and 19 related to asphyxial conditions (15.9%). The most common isolates were Staphylococcus aureus (28.7%) followed by Klebsiella (24.8%) and Pseudomonas aeruginosa (16.6 ). One hundred and nineteen (8.13%) of the neonates died in our study group. These results suggest that neonates with illiterate mothers with high parity and below average socioeconomic level were more susceptible to mortality in the early neonatal period. Most of the cases of mortality were due to specific infections.

    Conditional Poisson models have been used to analyze vaccine safety data from self-controlled case series (SCCS) design. In this paper, we derived the likelihood function of fixed effects models in analyzing SCCS data and showed that the likelihoods from fixed effects models and conditional Poisson models were proportional. Thus, the maximum likelihood estimates (MLEs) of time-varying variables including vaccination effect from fixed effects model and conditional Poisson model were equal. We performed a simulation study to compare empirical type I errors, means and standard errors of vaccination effect coefficient, and empirical powers among conditional Poisson models, fixed effects models, and generalized estimating equations (GEE), which has been commonly used for analyzing longitudinal data. Simulation study showed that both fixed effect models and conditional Poisson models generated the same estimates and standard errors for time-varying variables while GEE approach produced different results for some data sets. We also analyzed SCCS data from a vaccine safety study examining the association between measles mumps-rubella (MMR) vaccination and idiopathic thrombocytopenic purpura (ITP). In analyzing MMR-ITP data, likelihood-based statistical tests were employed to test the impact of time-invariant variable on vaccination effect. In addition a complex semi-parametric model was fitted by simply treating unique event days as indicator variables in the fixed effects model. We conclude that theoretically fixed effects models provide identical MLEs as conditional Poisson models. Because fixed effect models are likelihood based, they have potentials to address methodological issues in vaccine safety studies such as how to identify optimal risk window and how to analyze SCCS data with misclassification of adverse events.

    Background Results from epidemiologic studies on the relationship between vitamin D and breast cancer risk are inconclusive. It is possible that vitamin D may be effective in reducing risk only of specific subtypes due to disease heterogeneity. Methods and Findings In case-control and case-series analyses, we examined serum concentrations of 25-hydroxyvitamin D (25OHD) in relation to breast cancer prognostic characteristics, including histologic grade, estrogen receptor (ER), and molecular subtypes defined by ER, progesterone receptor (PR) and HER2, among 579 women with incident breast cancer and 574 controls matched on age and time of blood draw enrolled in the Roswell Park Cancer Institute from 2003 to 2008. We found that breast cancer cases had significantly lower 25OHD concentrations than controls (adjusted mean, 22.8 versus 26.2 ng/mL, p<0.001). Among premenopausal women, 25OHD concentrations were lower in those with high- versus low-grade tumors, and ER negative versus ER positive tumors (p≤0.03). Levels were lowest among women with triple-negative cancer (17.5 ng/mL), significantly different from those with luminal A cancer (24.5 ng/mL, p = 0.002). In case-control analyses, premenopausal women with 25OHD concentrations above the median had significantly lower odds of having triple-negative cancer (OR = 0.21, 95% CI = 0.08–0.53) than those with levels below the median; and every 10 ng/mL increase in serum 25OHD concentrations was associated with a 64% lower odds of having triple-negative cancer (OR = 0.36, 95% CI = 0.22–0.56). The differential associations by tumor subtypes among premenopausal women were confirmed in case-series analyses. Conclusion In our analyses, higher serum levels of 25OHD were associated with reduced risk of breast cancer, with associations strongest for high grade, ER negative or triple negative cancers in premenopausal women. With further confirmation in large prospective studies, these findings could warrant

    Full Text Available Abstract Distinguishing cohort studies from case series is difficult. We propose a conceptualization of cohort studies in systematic reviews of comparative studies. The main aim of this conceptualization is to clarify the distinction between cohort studies and case series. We discuss the potential impact of the proposed conceptualization on the body of evidence and workload. All studies with exposure-based sampling gather multiple exposures (with at least two different exposures or levels of exposure and enable calculation of relative risks that should be considered cohort studies in systematic reviews, including non-randomized studies. The term “enables/can” means that a predefined analytic comparison is not a prerequisite (i.e., the absolute risks per group and/or a risk ratio are provided. Instead, all studies for which sufficient data are available for reanalysis to compare different exposures (e.g., sufficient data in the publication are classified as cohort studies. There are possibly large numbers of studies without a comparison for the exposure of interest but that do provide the necessary data to calculate effect measures for a comparison. Consequently, more studies could be included in a systematic review. Therefore, on the one hand, the outlined approach can increase the confidence in effect estimates and the strengths of conclusions. On the other hand, the workload would increase (e.g., additional data extraction and risk of bias assessment, as well as reanalyses.

    Animal studies and in vitro human studies suggest that certain opioid analgesics impair crucial immune functions. This study was undertaken to determine whether opioid use is associated with increased risk of serious infection in patients with rheumatoid arthritis (RA). We conducted a self-controlled case series analysis on a retrospective cohort of 13,796 patients with RA enrolled in Tennessee Medicaid in 1995-2009. Within-person comparisons of the risk of hospitalization for serious infection during periods of opioid use versus non-use were performed using conditional Poisson regression. Fixed confounders were accounted for by design; time-varying confounders included age and use of disease-modifying antirheumatic drugs, glucocorticoids, and proton-pump inhibitors. In additional analyses, risks associated with new opioid use, use of opioids known to have immunosuppressive properties, use of long-acting opioids, and different opioid dosages were assessed. Sensitivity analyses were performed to account for potential protopathic bias and confounding by indication. Among 1,790 patients with RA who had at least 1 hospitalization for serious infection, the adjusted incidence rate of serious infection was higher during periods of current opioid use compared to non-use, with an incidence rate ratio (IRR) of 1.39 (95% confidence interval [95% CI] 1.19-1.62). The incidence rate was also higher during periods of long-acting opioid use, immunosuppressive opioid use, and new opioid use compared to non-use (IRR 2.01 [95% CI 1.52-2.66], IRR 1.72 [95% CI 1.33-2.23], and IRR 2.38 [95% CI 1.65-3.42], respectively). Results of sensitivity analyses were consistent with the main findings. In within-person comparisons of patients with RA, opioid use was associated with an increased risk of hospitalization for serious infection. © 2016, American College of Rheumatology.

    Full Text Available Introduction: Over two-thirds of Canadians are deficient in vitamin D. Clinical overlap can compound diagnosis of depression in vitamin D deficient individuals. Citing high costs, the Ministry of Health has restricted routine vitamin D screening and hence is not feasible. Objectives: The current case series is an attempt to recognise the clinical overlap between depression and vitamin D deficiency in order to avoid unnecessary antidepressant prescriptions and to demonstrate the role of collaborative care in such patients. Method: After appropriate ethics approval 62 patients from an outpatient clinic were screened for the diagnosis of treatment resistant depression. Those who had predominant somatic complaints were further screened for organic factors and those with inadequate vitamin D levels were referred to family physicians for supplementation with vitamin D. Results: More than 50% were detected deficient in vitamin D after our evaluation. They showed subjective improvement with vitamin D supplements. No modification of antidepressants was needed. Conclusion: Vitamin D deficiency should be suspected in depressed patients with prominent somatic symptoms and their treatment resistance should be reconsidered to avoid unnecessary exposure to mood stabilisers. Collaborating with primary care is advocated. Limitation: Co-prescription of an antidepressant is a confounder in our case series, and we propose more organised studies with objective rating scales.

    To determine the agents of recurrence, the demographic features, and the management and outcomes of pterygium cases treated at Aga Khan University Hospital (AKUH), Karachi. This hospital-based descriptive study included 147 patients with pterygium (147 eyes) from both sexes, who presented at the Ophthalmology Department at AKUH between January 1, 2002 and December 31, 2010. Data regarding their demographic profile and other factors were collected in a well-structured proforma. Data were analyzed using frequencies, proportions, group means, standard deviations, and Pearson's chi squared test. The male to female ratio in our study was 2:1, with factors such as younger age (<50 years) at presentation (P = 0.04, Pearson's chi squared test) and the presence of secondary pterygium (P = 0.050) correlated significantly with the recurrence of pterygium. There was a definite trend of decreased recurrence seen with lower grade of pterygium (P = 0.06). The recurrence rate in our study was 8.8 %. These results suggest that a younger age coupled with a higher grade of pterygium as well as a history of multiple recurrences leads to increased susceptibility of recurrence after surgical excision. Early diagnosis and appropriate management will lead to a better prognosis.

    Full Text Available Vorderman (1901 was the first to record blisters caused by beetles in medical literature. Blister beetle dermatitis is a cutaneous condition caused by the toxins released by blister beetles. The vesicant chemical in the body fluids of these insects causes an acute irritant contact dermatitis characterized by erythematovesicular lesions associated with burning sensation on exposed parts of the body. The aim of this study was to investigate the morphological patterns of blister beetle dermatitis. We conducted a 1-year (January–December 2014 prospective study of the clinical presentation of Paederus dermatitis noticed in urban and semiurban areas close to paddy fields in the Cauvery Basin, Mysuru, Karnataka. All patients with Paederus dermatitis attending the outpatient department of Department of Dermatology were recruited in the study with a total of 37 patients. Diagnosis was made on detailed history regarding onset of lesions, symptoms, as well as thorough clinical examination of the lesions. The peak time of presentation was June–September, the monsoon season in this part of India. The average duration of lesions at the time of presentation was 2–5 days. All patients had a history of burning and itchy sensation at night followed by full blown lesions the next morning, with the face, neck, and arms being the most common sites. Patients were predominantly males with the age range of 13–55 years. The most common presentations were linear erythematous plaques and erythematovesicles with a “burnt” appearance and a gray necrotic centre. “Kissing” lesions and periorbital involvement were seen in 5 and 6 patients, respectively. Species identification of the Paederus beetles was not done. Paederus dermatitis occurs in tropical regions. Awareness about the morphological patterns of the condition will prevent misdiagnosis. Simple preventive measures can be undertaken based on the behavioral pattern of this nocturnal beetle.

    Schwartz and Dell (2010) advocated for a major role for case series investigations in cognitive neuropsychology. They defined the key features of this approach and presented a number of arguments and examples illustrating the benefits of case series studies and their contribution to computational cognitive neuropsychology. In the Special Issue on "Case Series in Cognitive Neuropsychology" there are six commentaries on Schwartz and Dell as well as a response to the six commentaries by Dell and Schwartz (2011 this issue). In this paper, I provide a brief summary of the key points made in Schwartz and Dell, and I review the promise and perils of case series design as revealed by the six commentaries. I conclude by placing the set of papers within a broader perspective, providing some clarification of the historical record on case series and single-case approaches, raising some cautionary notes for case series studies and situating both case series and single-case approaches within the larger context of theory development in the cognitive sciences.

    Full Text Available Abstract Background Infantile colic is a common painful clinical condition associated with signs of distended intestines and an increase in colon peristalsis. However, clinical documentation of observed gastrointestinal functions in the condition is still lacking. Even though the ailment is common, no clear treatment guidelines exist. While acupuncture with minimal stimulation has been shown to be effective in reducing crying behaviour of infants suffering from colic, the documented effect of acupuncture on gastrointestinal function in children with infantile colic is scarce. This case series study aims to document the symptoms of routinely rated gastrointestinal function and the changes in these symptoms after minimal acupuncture in a larger group of children with infantile colic. Methods This study included 913 infants with normal weights, and lengths at birth. The infants' mean age was 5.4 weeks when the observations started, and had colic symptoms since two weeks after birth. Light needling stimulation of the acupuncture point LI4 was performed for 10-20 seconds bilaterally on a daily basis for a mean of 6.2 consecutive days. A questionnaire with verbal rating scales for the parents' evaluation was used before and after the treatment period. Results Before treatment the infants were assessed by the parents in terms of 'often have inflated stomachs' (99% and 'seldom drool' (76%, 'regurgitate' (53% and 'belch' (62%. Moreover, the reported frequency of defecation was 5-8 times per day (64%, with a yellowish-green colour (61% and with a water-thin consistency (74%. After treatment, the variables of inflated stomachs, drooling and regurgitating were systematically changed, and rated by the parents as occurring 'sometimes' while belching was rated as occurring 'often' and the frequency of defecation was reduced to 1-4 times/day with a mustard yellow colour and a gruel-like consistency. The parents also rated their impression of the infants

    Transvestism, commonly termed as cross-dressing, means to dress in the clothing of opposite sex. We describe a series of three cases with transvestism as one of their primary complaints. The discussion sheds light on the various ways in which transvestism as a symptom can present in Psychiatry. In the first two cases, there was lower intelligence. In first and third case, there were other paraphilia along with transvestism. Second case had co-morbid obsessive-compulsive disorder (OCD) and had good response to selective serotonin reuptake inhibitor (SSRI). PMID:27011411

    Over recent decades, hand, foot and mouth disease (HFMD) has emerged as a serious public health threat in the Asia-Pacific region because of its high rates of severe complications. Understanding the differences and similarities between mild and severe cases can be helpful in the control of HFMD. In this study, we compared the two types of HFMD cases in their temporal trends. We retrieved the daily series of disease counts of mild and severe HFMD cases reported in mainland China in the period of 2009-2014. We applied a quasi-Poisson regression model to decompose each series into the long-term linear trend, periodic variations, and short-term fluctuations, and then we compared each component between two series separately. A total of 11,101,860 clinical HFMD cases together with 115,596 severe cases were included into this analysis. We found a biennial increase of 24.46 % (95 % CI: 22.80-26.14 %) for the baseline of disease incidence of mild cases, whereas a biennial decrease of 8.80 % (95 % CI: 7.26-10.31 %) was seen for that of severe cases. The periodic variations of both two series could be characterized by a mixture of biennial, annual, semi-annual and eight-monthly cycles. However, compared to the mild cases, we found the severe cases vary more widely for the biennial and annual cycle, and started its annual epidemic earlier. We also found the short-term fluctuations between two series were still significantly correlated at the current day with a correlation coefficient of 0.46 (95 % CI: 0.43-0.49). We found some noticeable differences and also similarities between the daily series of mild and severe HFMD cases at different time scales. Our findings can help us to deepen the understanding of the transmission of different types of HFMD cases, and also provide evidences for the planning of the associated disease control strategies.

    Full Text Available Abstract Background Clinical trials assessing efficacy and safety of Intramuscular (IM Olanzapine in acute schizophrenia and acute mania have previously been undertaken in studies required for drug registration in patients who were required to give informed consent. These patients may have less severe forms of psychosis than patients treated in routine practice. Data derived from naturalistic practice following the launch of IM olanzapine may be helpful for clinicians in assessing efficacy and safety of IM olanzapine. The PANSS-EC scale used in the clinical studies may represent a tool that could be used in routine clinical practice. Case presentation We report on an early unselected case series of 7 patients who received IM olanzapine in routine clinical practice settings in the UK. In this case series, olanzapine IM was generally effective, and no adverse events were reported. Adjunctive benzodiazepines were given concomitantly in 1 of the 7 subjects. This is relevant as concomitant benzodiazepines are not recommended for a minimum of 1 hour post IM olanzapine administration. PANSS-EC data was collected in 2 of the 7 subjects. Conclusion Although patients had greater severity of psychosis than clinical trial patients there were no unexpected findings. In addition the PANSS-EC scale is a scale that may be useful in assessing the efficacy of IM antipsychotics in routine clinical practice.

    We developed a method to reconstruct land use history from Landsat images time-series. The method uses a breakpoint detection framework derived from the econometrics field and applicable to time-series regression models. The Breaks For Additive Season and Trend (BFAST) framework is used for defining the time-series regression models which may contain trend and phenology, hence appropriately modelling vegetation intra and inter-annual dynamics. All available Landsat data are used for a selected study area, and the time-series are partitioned into segments delimited by breakpoints. Segments can be associated to land use regimes, while the breakpoints then correspond to shifts in land use regimes. In order to further characterize these shifts, we classified the unlabelled breakpoints returned by the algorithm into their corresponding processes. We used a Random Forest classifier, trained from a set of visually interpreted time-series profiles to infer the processes and assign labels to the breakpoints. The whole approach was applied to quantifying the number of cultivation cycles in a swidden agriculture system in Brazil (state of Amazonas). Number and frequency of cultivation cycles is of particular ecological relevance in these systems since they largely affect the capacity of the forest to regenerate after land abandonment. We applied the method to a Landsat time-series of Normalized Difference Moisture Index (NDMI) spanning the 1984-2015 period and derived from it the number of cultivation cycles during that period at the individual field scale level. Agricultural fields boundaries used to apply the method were derived using a multi-temporal segmentation approach. We validated the number of cultivation cycles predicted by the method against in-situ information collected from farmers interviews, resulting in a Normalized Residual Mean Squared Error (NRMSE) of 0.25. Overall the method performed well, producing maps with coherent spatial patterns. We identified

    To determine the demographics, management, bacteriological spectrum, and outcome of brain abscesses of patients brought to Aga Khan University Hospital (AKUH), Karachi, with a history of neurologic symptoms and to examine the factors associated with it. This hospital-based descriptive study included 53 patients from both sexes who presented to the neurosurgery section at AKUH from January 1, 2000, until December 31, 2008, with neurologic symptomatology and fulfilling other inclusion criteria. Data regarding their demographic profile and other factors were collected in a well-structured proforma. Data were analyzed using frequencies, proportions, group means, and standard deviations. The male-to-female ratio in our study was 3.4:1, with Staphylococcus milleri (20.7%) being the most common etiologic agent followed by anaerobic bacteria (15.1%). The triad of headache, fever, and vomiting was present in 62.7% of patients at the time of presentation. The most important factors influencing mortality was the neurologic condition of the patient at the time of admission. Chronic suppurative otitis media was the most common predisposing factor for temporal lobe infections, and the frontal lobe was the most common site of involvement in majority of the patients (67.8%). The mortality rate in our study was 11.3%. Findings suggest that patients in the second and fourth decades of life are the most susceptible, both in terms of morbidity and mortality. Early diagnosis and appropriate management, along with rapid access to tertiary care centers, will lead to a better prognosis. Copyright © 2011 Elsevier Inc. All rights reserved.

    Chiropractic care is popular for low back pain, but may increase the risk for acute lumbar disc herniation (LDH). Low back pain is a common early (prodromal) symptom of LDH and commonly precedes LDH diagnosis. Our objective was to investigate the association between chiropractic care and acute LDH with early surgical intervention, and contrast this with the association between primary care physician (PCP) care and acute LDH with early surgery. Using a self-controlled case series design and population-based healthcare databases in Ontario, Canada, we investigated all adults with acute LDH requiring emergency department (ED) visit and early surgical intervention from April 1994 to December 2004. The relative incidence of acute LDH with early surgery in exposed periods after chiropractic visits relative to unexposed periods was estimated within individuals, and compared with the relative incidence of acute LDH with early surgery following PCP visits. 195 cases of acute LDH with early surgery (within 8 weeks) were identified in a population of more than 100 million person-years. Strong positive associations were found between acute LDH and both chiropractic and PCP visits. The risk for acute LDH with early surgery associated with chiropractic visits was no higher than the risk associated with PCP visits. Both chiropractic and primary medical care were associated with an increased risk for acute LDH requiring ED visit and early surgery. Our analysis suggests that patients with prodromal back pain from a developing disc herniation likely seek healthcare from both chiropractors and PCPs before full clinical expression of acute LDH. We found no evidence of excess risk for acute LDH with early surgery associated with chiropractic compared with primary medical care.

    Full Text Available Purpose: The purpose of this study is to study the clinical features, visual outcome, management, and ocular complications of ocular injury, following trauma with tennis or cricket ball. Methods: A prospective, noncomparative case study of patients having injury with tennis/cricket ball while playing cricket was conducted between January 2013 and April 2016. Seventy-six eyes of 76 patients were studied. Presenting vision, age, gender, time since injury, general and ocular examination, intraocular pressure, indirect ophthalmoscopy, B scan, and X-ray/computed tomography scan findings were noted. Patients were managed medically or surgically as per the need and followed up at least for 6 months. Results: Seventy-six eyes of 76 patients were studied. All cases were male, except two. Majority (80.2% were <25 years. Median presenting visual acuity (VA was 6/36 and median final VA was 6/18. Significant findings in the decreasing order of frequency were sphincter tear (26.3%, retinal detachment (23.6%, angle recession (18.4%, choroidal rupture (17.1%, and Berlin's edema (15.7%. Most of the cases (69.7% were managed medically. Only 30.2% cases needed surgical intervention. Final visual outcome in our study was depended on initial VA (P = 0.000. It was also correlating with presenting clinical feature (P = 0.010 and type of intervention (medical/surgical (P = 0.001. Conclusion: Cricket-related ocular injury generally has a poor prognosis with most cases being closed globe injury; retinal detachment is the most common vision-threatening presentation. In spite of being a common event, cricket-related injury is sparingly documented and hence needs further studies for proper documentation, prognostication, and formulation of definitive management plan.

    Distal locking is one challenging step during intramedullary nailing of femoral shaft fractures that can lead to an increase of radiation exposure. In the present study, the authors describe a technique for the distal locking of femoral nails, implementing a new targeting device in an attempt to reduce radiation exposure and operational time. Over a 2-year period, 127 consecutive cases of femoral shaft fractures were included in the study. All cases were treated with nailing of femoral shaft fractures with an unslotted reamed antegrade femoral nail and distal locking was performed with the use of a proximally mounted aiming device. Mean duration of the procedure was 63.5 18.1 min while the duration for distal locking was 6.6 +/- 2.6 min. In all successful cases, exposure from intraoperative fluoroscopy was 17.2 +/- 7.4 s for the whole operative procedure, and for distal locking was 2 shots, 1.35 s (range, 0.9-2.2 s) and 1.9 mGy (range, 1.1-2.9 mGy). Five cases (3.9%) were unsuccessful, but overall no intraoperative complications were encountered from the application of this technique. The ability of the device to correspond to the level of nail deformation and to properly identify the distal holes, reduced exposure to radiation compared to other published reports, and should be considered as a valuable tool for distal locking of femoral fractures.

    Veins as the source of trigeminal neuralgias (TN) lead to controversies. Only a few studies have specifically dealt with venous implication in neurovascular conflicts (NVC). The aim of this study was the anatomical-surgical description of the compressive veins found during micro-vascular decompression (MVD). Patients retained were those in whom a vein was considered compressive, alone, or in association with an artery. The study defined the type of vein involved, its situation along, the location around the root, and management. For this study, denomination of veins in relation with the root was revisited. Of the 326 consecutive patients who underwent MVD from 2005 to 2013, 124 (38.0 %) had a venous conflict, alone in 29 (8.9 %), or in association with an artery in 95 (29.1 %). The compressive veins belonged to one of the two venous systems described: the superficial or the deep superior petrosal venous system (sSPVS or dSPVS). A vein from sSPVS was found compressive in 81 cases (59.6 %), for the major part it was the pontine affluent of the superior petrosal vein (48 cases). The conflict was situated at TREZ in 28.4 %, mid-cisternal portion in 50.6 %, and porus in 8.6 %. The dSPVS was found compressive in 55 cases (40.4 %), almost always a transverse vein at porus (51 cases). Decompression was coagulation-division of the conflicting vein in 36.8 % and simple cleavage in the other. The study shows the frequent implication of veins in NVC as the source of TN. NVC are not only at TREZ but also at mid-cisternal portion and porus of Meckel cave.

    The authors analysed radiograms of the hands of 50 patients suffering from primary articular chondrocalcinosis (ACC) and compared them with those of 100 control subjects of similar sex and age. There were 40 women and 10 men, with an average age of 69.6 years (plus or minus 9.82). A chalky incrustation of the semilunar pyramidal interspace was observed in 40 percent of cases. The frequency of this incrustation was next in order of importance to incrustation of the triangular ligament which occurred in 52 percent of cases. The difference from the controls was highly significant (p less than 0.001). Voluminous geodes affecting one or more of the bone of the wrist were present in 20 percent of the patients with ACC and in 5 percent of the controls. The difference was significant (p less than 0.01). Chalky deposits were found in the soft tissues immediately next to a metacarpo-phalangeal articulation in 22 percent of the ACC patients but not in any of the controls. The difference was highly significant (p less than 0.001). These chalky deposits next to metacarpo-phalangeal articulations were always associated with chalky incrustation of the radio-carpal joint. As regards the radiological lesions, considered as being typical images of arthrosis and affecting the trapezo-metacarpal, metacarpo-phalangeal, and interphalangeal articulations, the chondrocalcinosis patients appeared to be more frequently affected than the controls, but the difference was not significant. On the other hand, a type of arthropathy occurs in ACC patients which also resembles an arthrosis radiologically but which was 5 times more frequent in them than in the controls and which in this series occurred without nearby trapezo-metacarpal arthropathy only in ACC patients (16 percent as against 0 percent in the controls: p less than 0.001); this was scapho-trapezial arthropathy. The finding of this kind of radiological lesion, particularly when it is not associated with lesions in the trapezo

    Regression analysis is an analysis to model the relationship between response variables and predictor variables. The parametric approach to the regression model is very strict with the assumption, but nonparametric regression model isn’t need assumption of model. Time series data is the data of a variable that is observed based on a certain time, so if the time series data wanted to be modeled by regression, then we should determined the response and predictor variables first. Determination of the response variable in time series is variable in t-th (yt), while the predictor variable is a significant lag. In nonparametric regression modeling, one developing approach is to use the Fourier series approach. One of the advantages of nonparametric regression approach using Fourier series is able to overcome data having trigonometric distribution. In modeling using Fourier series needs parameter of K. To determine the number of K can be used Generalized Cross Validation method. In inflation modeling for the transportation sector, communication and financial services using Fourier series yields an optimal K of 120 parameters with R-square 99%. Whereas if it was modeled by multiple linear regression yield R-square 90%.

    Underground water is regarded as considerable water source which is mainly available in arid and semi arid with deficient surface water source. Forecasting of hydrological variables are suitable tools in water resources management. On the other hand, time series concepts is considered efficient means in forecasting process of water management. In this study the data including qualitative parameters (electrical conductivity and sodium adsorption ratio) of 17 underground water wells in Mehran Plain has been used to model the trend of parameters change over time. Using determined model, the qualitative parameters of groundwater is predicted for the next seven years. Data from 2003 to 2016 has been collected and were fitted by AR, MA, ARMA, ARIMA and SARIMA models. Afterward, the best model is determined using information criterion or Akaike (AIC) and correlation coefficient. After modeling parameters, the map of agricultural land use in 2016 and 2023 were generated and the changes between these years were studied. Based on the results, the average of predicted SAR (Sodium Adsorption Rate) in all wells in the year 2023 will increase compared to 2016. EC (Electrical Conductivity) average in the ninth and fifteenth holes and decreases in other wells will be increased. The results indicate that the quality of groundwater for Agriculture Plain Mehran will decline in seven years.

    We aimed to describe the clinical and laboratory features as well as diagnostic difficulties in the case series of spondylodiscitis. We retrospectively reviewed 11 cases of spondylodiscitis. The diagnosis of spondylodiscitis was based on clinical, radiological and microbiological evidence and by the response to antimicrobial therapy. There were 7 men and 4 women, and the age ranged from 21 to 74 years. Risk factors of spondylodiscitis were observed in 7 patients. The approximate time from onset of symptoms to diagnosis was from 2 to 7 months (median 45 days). Back pain was the most common symptom. The most frequent location of spondylodiscitis was lumbar spine. Pathogens were isolated in 6 cases and were as follows: Staphylococcus aureus (4 cases), Staphylococcus warneri (1 case) and Escherichia coli (1 case). After therapy, all patients had rapid regression of symptoms and no permanent neurological impairments and recurrence of infection were observed. Diagnosis of spondylodiscitis is frequently delayed. This disease should be taken into consideration in differential diagnosis in patients with root syndromes accompanied by back pain and usually fever as well as increased values of CRP and ESR.

    Full Text Available Pseudocirrhosis describes morphological changes of the liver that closely mimic cirrhosis, without the typical histopathological changes seen in cirrhosis. It most commonly occurs in patients with metastatic breast cancer, although it has been reported in other malignancies as well. Like in cirrhosis, portal hypertension is often seen in patients with pseudocirrhosis. Pseudocirrhosis is a rare but important complication of metastatic cancer. In this case series and literature review, we describe 6 patients with hormone-receptor-positive metastatic breast cancer. We report the significant morbidity associated with pseudocirrhosis in the course of treatment in patients with metastatic breast cancer.

    Full Text Available Shabkola is a village located in Mazandaran province of northern Iran that suffers from the mass movement happening in the upstream. Deforestation and changes to land use are the main reasons for the soil instability in this region, which together with steep slope, relatively high precipitation rate and natural erosion has led to such a condition. The area of mass movement is approximately 90 hectares which is a big threat for people living in the region. In this study, we have utilized two different geodetic techniques including InSAR time-series analysis and GPS measurements to assess slope stability in Shabkola. The SAR dataset includes 19 ALOS/PALSAR images spanning from July 2007 to February 2011 while GPS observations are collected in 5 campaigns from September 2011 to May 2014. Displacement as much as approximately 11.7 m in slope direction was detected by GPS observations for the 2011-2014 time period. Most of the slope geometry is in north-south direction, for which the sensitivity of InSAR for displacement detection is low. However, ALOS PALSAR data analysis revealed a previously unknown landslide, covered by dense vegetation in the northern part of main Shabkola landslide, showing line-of-sight velocity of approximately 2cm/year in the time period 2007-2011.

    In the United States, nearly 1000 annual cases of heat stroke are reported but the frequency and outcome of severe liver injury in such patients is not well described. The aim of this study was to describe cases of acute liver injury (ALI) or failure (ALF) caused by heat stroke in a large ALF registry. Amongst 2675 consecutive subjects enrolled in a prospective observational cohort of patients with ALI or ALF between January 1998 and April 2015, there were eight subjects with heat stroke. Five patients had ALF and three had ALI. Seven patients developed acute kidney injury, all eight had lactic acidosis and rhabdomyolysis. Six patients underwent cooling treatments, three received N-acetyl cysteine (NAC), three required mechanical ventilation, three required renal replacement therapy, two received vasopressors, one underwent liver transplantation, and two patients died-both within 48 hours of presentation. All cases occurred between May and August, mainly in healthy young men because of excessive exertion. Management of ALI and ALF secondary to heat stroke should focus on cooling protocols and supportive care, with consideration of liver transplantation in refractory patients. © 2017 John Wiley & Sons A/S.

    Global navigation satellite systems (GNSS) data are a fundamental source of information for achieving a better understanding of geophysical and climate-related phenomena. However, discontinuities in the coordinate time series might be a severe limiting factor for the reliable estimate of long-term trends. A methodological approach has been adapted from Rodionov (Geophys Res Lett 31:L09204, 2004; Geophys Res Lett 31:L12707, 2006) and from Rodionov and Overland (J Marine Sci 62:328-332, 2005) to identify both the epoch of occurrence and the magnitude of jumps corrupting GNSS data sets without any a priori information on these quantities. The procedure is based on the Sequential t test Analysis of Regime Shifts (STARS) (Rodionov in Geophys Res Lett 31:L09204, 2004). The method has been tested against a synthetic data set characterized by typical features exhibited by real GNSS time series, such as linear trend, seasonal cycle, jumps, missing epochs and a combination of white and flicker noise. The results show that the offsets identified by the algorithm are split into 48 % of true-positive, 28 % of false-positive and 24 % of false-negative events. The procedure has then been applied to GPS coordinate time series of stations located in the southeastern Po Plain, in Italy. The series span more than 15 years and are affected by offsets of different nature. The methodology proves to be effective, as confirmed by the comparison between the corrected GPS time series and those obtained by other observation techniques.

    Current management of brachial plexus injuries includes nerve grafts and nerve transfers. However, in cases of late presentation or pan plexus injuries, free functional muscle transfers are an option to restore function. The purpose of our study was to describe and evaluate the rectus abdominis motor nerves histomorphologically and functionally as a donor nerve option for free functional muscle transfer for the reconstruction of brachial plexus injuries. High intercostal, rectus abdominis, thoracodorsal, and medial pectoral nerves were harvested for histomorphometric analysis from 4 cadavers from levels T3-8. A retrospective chart review was performed of all free functional muscle transfers from 2001 to 2014 by a single surgeon. Rectus abdominis nerve branches provide a significant quantity of motor axons compared with high intercostal nerves and are comparable to the anterior branch of the thoracodorsal nerve and medial pectoral nerve branches. Clinically, the average recovery of elbow flexion was comparable to conventional donors for 2-stage muscle transfer. Rectus abdominis motor nerves have similar nerve counts to thoracodorsal, medial pectoral nerves, and significantly more than high intercostal nerves alone. The use of rectus abdominis motor nerve branches allows restoration of elbow flexion comparable to other standard donors. In cases where multiple high intercostal nerves are not available as donors (rib fractures, phrenic nerve injury), rectus abdominis nerves provide a potential option for motor reconstruction without adversely affecting respiration.

    Double Sequence Defibrillation or Double Simultaneous Defibrillation (DSD) is the use of two defibrillators almost simultaneously at their highest allowed energy setting to treat refractory ventricular fibrillation (RVF). One set of pads is placed in the Anterior-Posterior position and the other set of pads is placed in the Anterior-Lateral Position. Both defibrillation buttons are pressed simultaneously. We sought to determine ROSC and survival rates in a large EMS system when DSD is routinely utilized for RVF. A retrospective case series was performed of all patients who received DSD from January 1, 2015 to April 30, 2015. During the four month period, we requested physicians to instruct paramedics to use DSD on patients after three refractory episodes of VF. All Advanced Cardiac Life Support (ALS) patients treated by paramedics are discussed via telephone communication with a physician in the system of 100 ALS treated patients per day. From January 1, 2015 to April 1, 2015, a total of 7 patients were treated with DSD. The mean age was 62 (Range: 45-78), with mean resuscitation time of 34.3 minutes before first DSD (Range: 23-48). The mean number of single shocks was 5.4 prior to DSD (Range: 3-9), with a mean of 2 DSD shocks delivered. VF converted after DSD in 5 cases (57.1%). Four patients survived to admission (43%). Three patients survived to discharge with no or minimal neurologic disability (28.6%). The mean Cerebral Performance Category Scale was 3.4 with 1 indicating good cerebral performance and 5 indicating Brain Death. The correct amount of energy in joules for VF remains unknown. In this case series, significant patients converted out of VF. The reason for improved VF conversion may be several factors including additional defibrillation vectors, increased energy, more energy across myocardium, and unknown variables. Additional research is underway to determine if routine DSD will result in improved survival compared to standard defibrillation

    normalization and stationarity were considered. Skewness test applied to evaluate normalization of evaporation, precipitation and stream flow time series and logarithmic transformation function executed for in order to improve normalization. Stationarity of studied time series were evaluated by well-known powerful ADF and KPSS stationarity tests. Time series model's order was determined using modified AICC test and the portmanteau goodness of fit test was used to evaluate the adequacy of developed linear time series models. Man-Kendall trend analysis was also conducted for the precipitation amount, the number of rainy days, the maximum precipitation with 24 hours duration, the evaporation and stream flow in monthly and annual time scales. Results and Discussion: Inferring to the physical base of ARMA models provided by Salas et al (1998, the precipitation has been considered independently and stochastically. If this assumption is not true in a given basin, it is expected that the MA component of stream flow discharge model be eliminated or washed out. This case occurred in basins A, B and C. In these basins, the behavior of precipitation and evaporation was autoregressive. It was observed that the stream flow discharge behavior also follows autoregressive models that had greater lags than precipitation and evaporation lags. This result proved that the precipitation, evaporation, and stream flow processes in the basin were regular processes. In basin D, the behavior of precipitation was stochastic and followed the MA model, which was related to the stochastic processes. In this basin, the stochastic behavior of precipitation affected the stream flow behavior, and it was observed that the stochastic term of MA also appeared in the stream flow. Thus, this leads to decrease the memory of stream flow discharge. The fact that the MA component in the stream flow discharge was greater than the MA component in precipitation indicated that during the process of producing stream flow

    This multicenter prospective case series study aimed to evaluate the outcome of periodontal regenerative therapy using a deproteinized bovine bone mineral (DBBM) in combination with a collagen barrier (CB) in the treatment of intrabony defects. A total of 36 nonsmoking patients with chronic periodontitis were recruited in five centers in Japan. All patients had at least one intrabony defect of ≥ 3 mm. The surgical procedures included access for debridement using a papilla preservation technique. Defects were filled with DBBM and covered with CB. Clinical evidence after 6 months supported the effectiveness of the combination therapy in the treatment of intrabony defects.

    Full Text Available In addition to forest encroachment, forest fire is a serious problem in Indonesia. Attempts at managing its widespread and frequent occurrence has led to intensive use of remote sensing data. Coarse resolution images have been employed to derive hot spots as an indicator of forest fire. However, most efforts to verify the hot spot data and to verify fire accidents have been restricted to the use of medium or high resolution data. At present, it is difficult to verify solely upon those data due to severe cloud cover and low revisit time. In this paper, we present a method to validate forest fire using NDVI time series data. With the freely available NDVI data from SPOT VEGETATION, we successfully detected changes in time series data which were associated with fire accidents.

    Full Text Available Introduction: Time series models are one of the most important tools for investigating and modeling hydrological processes in order to solve problems related to water resources management. Many hydrological time series shows nonstationary and nonlinear behaviors. One of the important hydrological modeling tasks is determining the existence of nonstationarity and the way through which we can access the stationarity accordingly. On the other hand, streamflow processes are usually considered as nonlinear mechanisms while in many studies linear time series models are used to model streamflow time series. However, it is not clear what kind of nonlinearity is acting underlying the streamflowprocesses and how intensive it is. Materials and Methods: Streamflow time series of 6 hydro-gauge stations located in the upstream basin rivers of ZarrinehRoud dam (located in the southern part of Urmia Lake basin have been considered to investigate stationarity and nonlinearity. All data series used here to startfrom January 1, 1997, and end on December 31, 2011. In this study, stationarity is tested by ADF and KPSS tests and nonlinearity is tested by BDS, Keenan and TLRT tests. The stationarity test is carried out with two methods. Thefirst one method is the augmented Dickey-Fuller (ADF unit root test first proposed by Dickey and Fuller (1979 and modified by Said and Dickey (1984, which examinsthe presence of unit roots in time series.The second onemethod is KPSS test, proposed by Kwiatkowski et al. (1992, which examinesthestationarity around a deterministic trend (trend stationarity and the stationarity around a fixed level (level stationarity. The BDS test (Brock et al., 1996 is a nonparametric method for testing the serial independence and nonlinear structure in time series based on the correlation integral of the series. The null hypothesis is the time series sample comes from an independent identically distributed (i.i.d. process. The alternative hypothesis

    Full Text Available Dens invaginatus (DI (dens in dente is a developmental anomaly resulting from an invagination in part of variable depth of the enamel organ into the dental papilla in the surface of the crown before calcification of the dental tissues. This anomaly usually involves the upper lateral incisors. These teeth are frequently expressed by an unusual form of crown and accentuation in the cingulum or a cusp. They are a target for caries leading to pulp necrosis and apical pathosis, so the diagnosis and early prevention measures are important. When treatment is necessary, conservative, endodontic, and periodontal possibilities are very effective. Surgical interventions are only rarely indicated. The present paper deals with the treatment of series cases with DI.

    2001-12-01

    This paper reports on a series of case studies where improvements were sought in muscle tone and gait in children with cerebral palsy. A Midfoot Control Ankle Foot Orthosis (AFO) was developed to control foot position in a cohort of patients with cerebral palsy (CP). The concept of controlling midfoot and hindfoot with an encapsulated internal Supra-Malleolar AFO that fitted into an external AFO was shown to be effective in ambulant children with CP. Some initial problems of compliance were noted and postulated to be due to difficulties associated with previous orthotic devices. Evidence from the case studies suggest that the developed Supra-Malleolar AFO orthoses enables children with CP to maintain mobility without skin tissue damage, delays the need for surgery and at the same time maintains the length of the Triceps Surae (Gastrocnemius and Soleus) complex. Plans for further research are discussed which will contribute to the evidence base for this particular orthotic device.

    Up to nowadays, satellite data have become increasingly available, thus offering a low cost or even free of charge unique tool, with a great potential for operational monitoring of vegetation cover, quantitative assessment of urban expansion and urban sprawl, as well as for monitoring of land use changes and soil consumption. This growing observational capacity has also highlighted the need for research efforts aimed at exploring the potential offered by data processing methods and algorithms, in order to exploit as much as possible this invaluable space-based data source. The work herein presented concerns an application study on the monitoring of vegetation cover and urban sprawl conducted with the use of satellite Landsat TM data. The selected test site is the Iguazu park highly significant, being it one of the most threatened global conservation priorities (http://whc.unesco.org/en/list/303/). In order to produce synthetic maps of the investigated areas to monitor the status of vegetation and ongoing subtle changes, satellite Landsat TM data images were classified using two automatic classifiers, Maximum Likelihood (MLC) and Support Vector Machines (SVMs) applied by changing setting parameters, with the aim to compare their respective performances in terms of robustness, speed and accuracy. All process steps have been developed integrating Geographical Information System and Remote Sensing, and adopting free and open source software. Results pointed out that the SVM classifier with RBF kernel was generally the best choice (with accuracy higher than 90%) among all the configurations compared, and the use of multiple bands globally improves classification. One of the critical elements found in the case of monitoring of urban area expansion is given by the presence of urban garden mixed with urban fabric. The use of different configurations for the SVMs, i.e. different kernels and values of the setting parameters, allowed us to calibrate the classifier also to

    Epidemiologic data on phocomelia are scarce. This study presents an epidemiologic analysis of the largest series of phocomelia cases known to date. Data were provided by 19 birth defect surveillance programs, all members of the International Clearinghouse for Birth Defects Surveillance and Research. Depending on the program, data corresponded to a period from 1968 through 2006. A total of 22,740,933 live births, stillbirths and, for some programs, elective terminations of pregnancy for fetal anomaly (ETOPFA) were monitored. After a detailed review of clinical data, only true phocomelia cases were included. Descriptive data are presented and additional analyses compared isolated cases with those with multiple congenital anomalies (MCA), excluding syndromes. We also briefly compared congenital anomalies associated with nonsyndromic phocomelia with those presented with amelia, another rare severe congenital limb defect. A total of 141 phocomelia cases registered gave an overall total prevalence of 0.62 per 100,000 births (95% confidence interval: 0.52–0.73). Three programs (Australia Victoria, South America ECLAMC, Italy North East) had significantly different prevalence estimates. Most cases (53.2%) had isolated phocomelia, while 9.9% had syndromes. Most nonsyndromic cases were monomelic (55.9%), with an excess of left (64.9%) and upper limb (64.9%) involvement. Most nonsyndromic cases (66.9%) were live births; most isolated cases (57.9%) weighed more than 2,499 g; most MCA (60.7%) weighed less than 2,500 g, and were more likely stillbirths (30.8%) or ETOPFA (15.4%) than isolated cases. The most common associated defects were musculoskeletal, cardiac, and intestinal. Epidemiological differences between phocomelia and amelia highlighted possible differences in their causes.

    To describe three cases of pericarditis probably related to azacitidine administration in a span of 3 years at our center. Case series. Comprehensive cancer center within a large, academic medical center. Three patients with high-grade myelodysplastic syndrome or acute myeloid leukemia who received azacitidine. None. None. Patient 1 presented with pericarditis after cycle 2 of azacitidine, patient 3 presented 3 weeks after completing cycle 5, and patient 2 presented during cycle 1. All patients were treated symptomatically and responded to corticosteroids. None of the patients were re-challenged with hypomethylating agents. Use of the Naranjo adverse drug reaction probability scale indicated a probable adverse drug reaction (score of 6) for patients 1 and 3 and a possible adverse drug reaction (score of 3) for patient 2. With the exclusion of other common causes of pericarditis, we believe it is likely that azacitidine was responsible for the findings in our patients. Providers caring for patients receiving hypomethylating agents should consider this potential adverse drug reaction in the setting of unexplained chest pain or other clinical signs consistent with cardiotoxicity. © 2016 Pharmacotherapy Publications, Inc.

    Full Text Available OBJECTIVE: To study the effect of platelet-rich plasma (PRP on contaminated problematic skin ulcers in patients with diabetes. MATERIAL AND METHODS: A total of 6 patients had been treated within the period from 2012 to 2014; they had various types of problematic wounds and diabetes type 2. Patients’ distribution by sex was as follows: 1 man and 5 women; mean age- 68 years. Ulcer types: acute (2 patients, hard-to-heal (2 patients and chronic (2 patients ulcers. The mean size of the skin and soft tissue defect was 9,5 cm2. Pathogenic microflora was isolated in 4 patients - S. aureus in three and Е. Coli in one. Based on a scheme developed by us, all cases were treated by administering platelet-rich plasma, derived by PRGF Endoret system. Follow-up period was within 4 – 6 months (4,5 on average. We used platelet rich plasma derived by PRGF Endoret system, applied on the wound bed on a weekly basis. RESULTS: Application of PRP allowed successful closure of all wounds. There were no complications associated with treatment of PRP. Epithelialization of the wound took 15 weeks on average for all patients. One patient presented with hyperkeratosis. Initial score of followed wounds, based on the scales are as follows: Total wound score – 10 p. Total anatomic score – 8 p. Total score – 15 p. at the initial stage. At the end of the treatment period scores were as follows - 0 p., which means excellent results CONCLUSION: We believe that the application of PRP may become optimal therapy in the treatment of contaminated problematic wounds in diabetic patients. PRP not only stimulates wound healing, but also has antimicrobial properties, which may contribute to the prevention of infections.

    The treatment of open femur fractures with reimplantation of large extruded segments remains one of the most difficult clinical management scenarios. The situation is even complicated when the extruded segments contains a large osteoarticular segment and no consensus exist about the efficient sterilization. We successfully managed five cases of open femur fracture by reimplantation of a large osteoarticular segment. While the outcomes were favourable, we performed an in vitro investigation in a rat model to determine whether the bone segment preparation strategy was optimal. After meticulous debridement and sterilization with povidone-iodine scrub/orthopaedic antibiotic solution, osteoarticular segments of the femur were reimplanted successfully in five patients with Gustilo-Anderson IIIa-IIIb fractures. Furthermore, in vitro study performed to assess the relative efficacy of various methods of sterilization employed osteoarticular segments of rat femurs. After contamination, osteoarticular segments were treated via one of the following protocols: (1) saline rinse; (2) povidone-iodine scrub and saline rinse; (3) povidone-iodine scrub and autoclaving; (4) povidone-iodine scrub and immersion in antibiotic solution; (5) povidone-iodine scrub and immersion in povidone-iodine solution; or (6) povidone-iodine scrub and gamma-irradiation. The osteoarticular segments were then cultured and finally evaluated for infection and morphological changes. At the mean 40 month follow-up, there were no infection in the patients and the fractures achieved completed union. For the basic research, only approaches involving povidone-iodine scrub with autoclaving or antibiotic solution immersion were 100% effective in eliminating bacterial growth. Furthermore, povidone-iodine scrub with antibiotic solution immersion preserved the articular surface morphology. Our study suggests that reimplantation of extruded osteoarticular segments of long bone may represent a feasible alternative to

    Cognitive-behavioral therapy for insomnia (CBTi) has demonstrated considerable efficacy within randomized clinical trials and case-series designs. This case-series study in a community sleep medicine clinic assessed the effectiveness of an eight-session CBTi protocol chronic insomnia patients who were allowed to continue their use of hypnotics (intent-to-treat n = 48), administered by a clinical psychology doctoral student receiving training and supervision in CBTi by a behavioral sleep medicine certified clinician. Outcome measures included daily sleep diaries, self-report measures on insomnia severity, dysfunctional beliefs and attitudes about sleep, daytime sleepiness, as well as medication usage. Patients showed significant improvements in sleep onset latency, wake time after sleep onset, sleep efficiency, insomnia severity, and dysfunctional sleep beliefs from pre- to post-treatment. No changes were seen in daytime sleepiness - patients were not excessively sleepy either before or after treatment. Use of sleep medication declined significantly from 87.5% pre-treatment to 54% post-treatment, despite no active efforts to encourage patients to withdraw. Results demonstrate that a CBTi conducted in a community sleep medicine clinic with patients not required to discontinue sleep-related medications can have similar effects as therapy delivered among those not on medication. 2009 Elsevier Ltd.

    Sachdev, Amun; Shafi, Fariha; Mehta, Purnima; Ahluwalia, Harpreet

    There are very few published cases of periocular keratin horns that have been reported in children. This study reports 2 pediatric cases of periocular keratin horns. The authors describe a 7-year-old male child who developed a keratin horn on the right lower eyelid and a 16-year-old female who developed a caruncular keratin horn. Both cases underwent excision biopsy, and subsequent histology confirmed that there was no evidence of malignancy. However, on the basis of the current evidence in adults and the difficulty in drawing firm conclusions from the small number of reported pediatric cases, the authors suggest that these lesions should be carefully managed due to the possibility of premalignant or malignant change at the base of the lesion.

    Hercman, H.; Pawlak, J.

    2012-04-01

    We present MOD-AGE - a new system for chronology construction. MOD-AGE can be used for profiles that have been dated by different methods. As input data, the system uses the following basic measurements: activities, atomic ratios or age, as well as depth measurement. Based on probability distributions describing the measurement results, MOD-AGE estimates the age~depth relation and its confidence bands. To avoid the use of difficult-to-meet assumptions, MOD-AGE uses nonparametric methods. We applied a Monte Carlo simulation to model age and depth values based on the real distribution of counted data (activities, atomic ratios, depths etc.). Several fitting methods could be applied for estimating the relationships; based on several tests, we decide to use LOESS method (locally weighted scatterplot smoothing). The stratigraphic correction procedure applied in the MOD-AGE program uses a probability calculus, which assumes that the ages of all the samples are correctly estimated. Information about the probability distribution of the samples' ages is used to estimate the most probable sequence that is concordant according to the superposition rule. MOD-AGE is presented as a tool for the chronology construction of speleothems that have been analyzed by the U-series method, and it is compared to the StalAge algorithm presented by D. Scholtz and D.L Hoffmann (2011). Scholtz, D., Hoffmann, D. L., 2011. StalAge - An algorithm designed for construction of speleothem age models. Quaternary Geochronology 6, 369-382.

    Full Text Available A smile expresses a feeling of joy, success, sensuality, affection and courtesy, and reveals self confidence and kindness. The harmony of the smile is determined not only by the shape, the position and the color of the teeth but also by the gingival tissues. Gingival health and appearance are essential components of an attractive smile. Gingival pigmentation results from melanin granules, which are produced by melanoblasts. The degree of pigmentation depends on melanoblastic activity. Although melanin pigmentation of the gingiva is completely benign and does not present a medical problem, complaints of ′black gums′ are common particularly in patients having a very high smile line (gummy smile. For depigmentation of gingiva different treatment modalities have been reported like- Bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery and laser. In the present case series bur abrasion, scraping, partial thickness flap (epithelial excision cryotherapy and electrosurgery have been tried for depigmentation, which are simple, effective and yield good results, along with good patient satisfaction.

    As a highly rare congenital defect, cor triatriatum sinister represents only 0.1% of congenital cardiac anomalies. Depending on the degree of obstruction and the accompanying symptoms, cor triatriatum can be diagnosed at any age. This case series described 5 patients with cor triatriatum sinister who underwent operation. Five patients with cor triatriatum sinister were seen at our institution between 2007 and 2013. The demographic characteristics and surgical results of these patients are outlined in this retrospective review. The surgical approach consists of left or right atriotomy, excision of the obstructing membrane, and repair of the associated intracardiac anomalies. After an uneventful postoperative hospital stay, all patients were discharged 5-10 days postoperatively. There were no instances of recurrent constriction after surgical treatment of the cor triatriatum membrane. Patients were followed up for a median of 4 years and were symptom free. In the surgical management of this easily and fully treatable congenital cardiac anomaly, it is difficult to determine which atriotomy approach is comparatively more advantageous. However, in the management of cor triatriatum sinister, priority should be given to confirmation of the diagnosis and full resection of the membrane. Thus, the surgeon should not hesitate to perform additional incisions if deemed necessary.

    Full Text Available Fireworks are used to celebrate a variety of religious, patriotic, and cultural holidays and events around the world. Fireworks are common in the United States, with the most popular holiday for their use being national Independence Day, also known as July Fourth. The use of fireworks within the context of celebrations and holidays presents the ideal environment for accidents that lead to severe and dangerous injuries. Injuries to the face from explosions present a challenging problem in terms of restoring ideal ocular, oral, and facial function. Despite the well documented prevalence of firework use and injury, there is a relatively large deficit in the literature in terms of firework injury that involves the face. We present a unique case series that includes 4 adult male patients all with severe firework injuries to the face that presented at an urban level 1 trauma center. These four patients had an average age of 26.7 years old and presented within 5 hours of each other starting on July Fourth. Two patients died from their injuries and two patients underwent reconstructive surgical management, one of which had two follow up surgeries. We explore in detail their presentation, management, and subsequent outcomes as an attempt to add to the very limited data in the field of facial firework blast injury. In addition, the coincidence of their presentation within the same 5 hours brings into question the availability of the fireworks involved, and the possibility of similar injuries related to this type of firework in the future.

    Full Text Available Abstract Introduction Transmissible spongiform encephalopathies are a group of neurodegenerative diseases of humans and animals. Genetic Creutzfeldt-Jakob diseases, in which mutations in the PRNP gene predispose to disease by causing the expression of abnormal PrP protein, include familial Creutzfeldt-Jakob disease, Gerstmann-Straussler-Scheinker syndrome and fatal familial insomnia. Case presentation A 47-year-old Han-Chinese woman was hospitalized with a 2-year history of progressive dementia, tiredness, lethargy and mild difficulty in falling asleep. On neurological examination, there was severe apathy, spontaneous myoclonus of the lower limbs, generalized hyperreflexia and bilateral Babinski signs. A missense mutation (T to G was identified at the position of nt 341 in one PRNP allele, leading to a change from glycine (Gly to valine (Val at codon 114. PK-resistant PrPSc was detected in brain tissues by Western blotting and immunohistochemical assays. Information on pedigree was collected notably by interviews with family members. A further four suspected patients in five consecutive generations of the family have been identified. One of them was hospitalized for progressive memory impairment at the age of 32. On examination, he had impairment of memory, calculation and comprehension, mild ataxia of the limbs, tremor and a left Babinski sign. He is still alive. Conclusion This family with G114V inherited prion disease is the first to be described in China and represents the second family worldwide in which this mutation has been identified. Three other suspected cases have been retrospectively identified in this family, and a further case with suggestive clinical manifestations has been shown by gene sequencing to have the causal mutation.

    Full Text Available Despite the development of radiotherapy machines and technologies, a proportion of patients suffer from radiation-induced lymphedema. Saireito (SRT is a traditional Japanese herbal medicine that has been used for treating edema and inflammation in conditions such as nephritic disease. This study investigated the effect of SRT on lymphedema caused by radiotherapy. Four patients were treated with SRT at a dose of 9 g/day. The severity of lymphedema was evaluated using the Common Terminology Criteria for Adverse Events version 4 and Numerical Rating Scale before and after SRT treatment. After the treatment with SRT, 2 of 4 patients (50% showed apparent improvement in lymphedema. One of the cases had difficulty in wearing the custom-made thermoplastic cast, but after SRT administration, he could wear the mask easily. One case decided to stop taking SRT 3 days after initiation because cough and fever appeared. In conclusion, it is important to control the side effects of radiotherapy, which leads to improved tumor control rates. Prospective randomized studies are necessary to confirm the findings of this case series study.

    Measles is a highly contagious viral infection and still a leading cause of vaccine-preventable deaths in Africa; especially in unvaccinated populations. We reviewed the medical reports of the measles outbreak that occurred in Misaje, in the North west region of Cameroon from 11/03/2015 to 14/05/2015. Six measles cases were recorded during this period; three of them complicated by bacterial infections. Measles should be considered as a differential diagnosis for any febrile rash especially among poorly vaccinated populations. Primary preventive methods implemented by clinicians could help control outbreaks; especially with delays in public health intervention. Also, gaps in health policies in Cameroon should be addressed to scale up vaccination coverage in remote communities like Misaje to reduce the incidence of measles outbreaks.

    The aim of the present study was to describe the characteristics of migraine with aura (MwA) in a case series of patients with headache onset before 12 years of age. We considered all consecutive patients referred to the Parma Headache Centre between 1975 and 2015 affected by MwA, diagnosed by our team of trained neurologists; the cases were subsequently reviewed applying the ICHD3-beta criteria. We then identified those cases with headache age-of-onset aura was the most common type of aura, followed by sensory and speech disturbances; however, these two latter aura symptoms were significantly more common among pediatric cases. In this group of patients, aura without headache was significantly less frequent (1.8 vs 5.3%); furthermore, headache had migraine characteristics in a higher proportion of cases (90.1 vs 82.6%). A family history of MwA was significantly more frequent among cases with pediatric onset (31.1 vs 16.9%). Males but not females with pediatric MwA had more frequently a comorbid migraine without aura (27.6 vs 16.8%). Among cases with pediatric onset, we did not find any significant differences between males and females. In conclusion, in our very large case series of MwA, patients with headache onset before 12 years of age seem to have a specific clinical phenotype, without significant gender differences.

    2010-01-01

    Background To use a new medium to dynamically visualize serial optical coherence tomography (OCT) scans in order to illustrate and elucidate the pathogenesis of idiopathic macular hole formation, progression, and surgical closure. Case Presentations Two patients at the onset of symptoms with early stage macular holes and one patient following repair were followed with serial OCTs. Images centered at the fovea and at the same orientation were digitally exported and morphed into an Audiovisual Interleaving (avi) movie format. Morphing videos from serial OCTs allowed the OCTs to be viewed dynamically. The videos supported anterior-posterior vitreofoveal traction as the initial event in macular hole formation. Progression of the macular hole occurred with increased cystic thickening of the fovea without evidence of further vitreofoveal traction. During cyst formation, the macular hole enlarged as the edges of the hole became elevated from the retinal pigment epithelium (RPE) with an increase in subretinal fluid. Surgical repair of a macular hole revealed initial closure of the macular hole with subsequent reabsorption of the sub-retinal fluid and restoration of the foveal contour. Conclusions Morphing videos from serial OCTs are a useful tool and helped illustrate and support anterior-posterior vitreofoveal traction with subsequent retinal hydration as the pathogenesis of idiopathic macular holes.

    2016-01-01

    Syphilis is an infectious disease caused by the bacterium Treponema pallidum. Syphilis has three clinical stages and may present various oral manifestations, mainly at the secondary stage. The disease mimics other more common oral mucosa lesions, going undiagnosed and with no proper treatment. Despite the advancements in medicine toward prevention, diagnosis, and treatment syphilis remains a public health problem worldwide. In this sense, dental surgeons should be able to identify the most common manifestations of the disease in the oral cavity, pointing to the role of this professional in prevention and diagnosis. This study describes a case series of seven patients with secondary syphilis presenting different oral manifestations. Copyright © 2016 Elsevier Editora Ltda. All rights reserved.

    A multivariate statistical approach is presented that allows a systematic search for relationships between the interannual variability in climate records and ecological time series. Statistical models are built between climatological predictor fields and the variables of interest. Relationships are sought on different temporal scales and for different seasons and time lags. The possibilities and limitations of this approach are discussed in four case studies dealing with salinity in the German Bight, abundance of zooplankton at Helgoland Roads, macrofauna communities off Norderney and the arrival of migratory birds on Helgoland. (orig.) [Deutsch] Ein statistisches, multivariates Modell wird vorgestellt, das eine systematische Suche nach potentiellen Zusammenhaengen zwischen Variabilitaet in Klima- und oekologischen Zeitserien erlaubt. Anhand von vier Anwendungsbeispielen wird der Klimaeinfluss auf den Salzgehalt in der Deutschen Bucht, Zooplankton vor Helgoland, Makrofauna vor Norderney, und die Ankunft von Zugvoegeln auf Helgoland untersucht.

    2008-06-01

    Full Text Available Abstract Introduction Gastrojejunocolic (GJC fistulae represent a significant post-surgical cause of morbidity and mortality. GJC fistulae represent rare post-surgical complications, and most are associated with gastric surgery. In the past, this complication has been under-recognized because a fistula may form years after surgery. Case presentation We describe two cases of gastrojejunocolic fistula in men aged 67 and 60 who both initially presented with watery diarrhea and weight loss. Upper GI studies with small bowel follow-through or barium contrast enema studies allowed a conclusive diagnosis to be made. Both patients underwent one-stage en bloc resection, and their postoperative course was uneventful. Conclusion With surgery, this condition is entirely correctable. Pre-operative nutritional status should be evaluated in patients undergoing corrective surgery, and total parenteral nutrition plays a major role in the provision of bowel rest to allow recovery in malnourished patients.

    To explore the effectiveness of neurorehabilitative training using an electroencephalogram-based brain- computer interface for hand paralysis following stroke. A case series study. Eight outpatients with chronic stroke demonstrating moderate to severe hemiparesis. Based on analysis of volitionally decreased amplitudes of sensory motor rhythm during motor imagery involving extending the affected fingers, real-time visual feedback was provided. After successful motor imagery, a mechanical orthosis partially extended the fingers. Brain-computer interface interventions were carried out once or twice a week for a period of 4-7 months, and clinical and neurophysiological examinations pre- and post-intervention were compared. New voluntary electromyographic activity was measured in the affected finger extensors in 4 cases who had little or no muscle activity before the training, and the other participants exhibited improvement in finger function. Significantly greater suppression of the sensory motor rhythm over both hemispheres was observed during motor imagery. Transcranial magnetic stimulation showed increased cortical excitability in the damaged hemisphere. Success rates of brain-computer interface training tended to increase as the session progressed in 4 cases. Brain-computer interface training appears to have yielded some improvement in motor function and brain plasticity. Further controlled research is needed to clarify the role of the brain-computer interface system.

    To determine the usefulness of a complete neuroandrologic evaluation and SPACE (Single Potential Analysis Cavernous Electromyography) in the study of impotence. We performed a clinical study, erection test with papaverine-phentolamine and neuroandrologic evaluation (bulbocavernous EMG, S2-S4 evoked potentials, evoked somatosensorial potentials, SPACE, D10-L2 skin sympathetic potentials, cystometrogram, and filling videocystography) in 180 patients consulting for impotence. We observed a relationship between the clinical diagnosis of impotence and the data from the neuroandrogenic study. The results of the study were classified as normal [in the clinical diagnosis of psychogenic impotence (100%), hormonal (80%) and vascular (60%)], abnormal [prevalent in the clinical diagnosis of structural impotence (87%)]. The erection test was mainly negative in all clinical diagnoses of impotence, except in psychogenic and vascular impotence (60% positive tests). The clinical data are useful in the diagnosis of impotence. The pharmacological erection test was not found to be very reliable. Complete neuroandrologic evaluation is indicated in non typified and mixed impotence, and can be performed in neurogenic impotence to identify the level of the lesion. Alone, SPACE does not appear to be useful as a screening test for neurologic lesions, but can be useful as a screening test for neuromuscular cavernous lesions. SPACE is indicated in structural, vascular and hormonal impotence. If SPACE is abnormal, the differential diagnosis between neurogenic and myogenic lesion can be made through a complete neuroandrologic evaluation.

    1992-01-01

    Village agroforestry systems in Sri Lanka have evolved through farmers' efforts to meet their survival needs. The paper examines farmers' land-use systems and their perceptions of the role of trees in the villages of Bambarabedda and Madugalla in central Sri Lanka. The benefits of village agroforestry are diverse food, fuelwood, fodder, timber, and mulch, but food products are of outstanding importance. The ability of Artocarpus heterophyllus (the jackfruit tree) and Cocos nucifera (coconut) to ensure food security during the dry season and provide traditional foods throughout the year, as well as to grow in limited space, make them popular crops in the two study villages. The study recommends that further research precede the formulation of agricultural interventions and that efforts to promote improved tree varieties recognize farmers' practices and expressed needs.

    This study aimed to evaluate the effectiveness of neurofeedback on attention deficit hyperactivity disorder. This is a quasi-experimental study without a control group. The study population included all children aged 5 to 12 years old affected with attention deficit hyperactivity disorders in Tehran, Iran who were referred to psychiatric clinics and given the diagnosis. The sample included 12 children with attention deficit hyperactivity disorder who were selected based on their availability (non-random sampling). They received 30 sessions of neurofeedback treatment, 2 times per week. Before and after neurofeedback training, the children were evaluated and compared with the use of cognitive assessment system test. Data were analyzed using dependent T-test. The total mean score for pretest was 88.81 while the total mean score for the post test was 82.23. The mean in pretest for attention hyperactivity disorder was higher than the mean in the post test. Moreover, The difference of pretest and post test scores of children affected with learning disorder associated with ADHD was calculated that showed significant (P=0.003). Neurofeedback is effective in the improvement of attention deficit hyperactivity disorder.

    Placental growth factor (PlGF) has been suggested as a possible biomarker for major placenta-related disorders such as preeclampsia and intrauterine growth restriction. However, experimental findings suggest that PlGF concentrations may be influenced by other factors besides the placenta. In the present study, we examined how acute fetal injury affects PlGF concentrations in maternal circulation. We therefore monitored PlGF concentrations in maternal circulation before and after feticide. A prospective comparative study was performed. Blood samples were drawn prospectively between January and July 2012, before and after feticide at predetermined time points in relation to the procedure (0, 30, 60, and 120 min). The levels of lactate dehydrogenase (LDH) in the maternal circulation were measured to detect acute tissue damage. PlGF concentrations were measured by standard human ELISA. Following feticide (60 and 120 min), PlGF concentrations decreased significantly compared to the concentrations before feticide. LDH concentrations did not change before and after feticide. Our finding, along with the detailed review of the literature described in our work, supports a new concept in which primary fetal distress can affect PlGF concentration in maternal circulation. A large-scale study is required to strengthen our finding.

    Soil salinity is one of the main causes of desertification and land degradation which has negative impacts on soil fertility and crop productivity. Monitoring salt affected areas and assessing land cover changes, which caused by salinization, can be an effective approach to rehabilitate saline soils and prevent further salinization of agricultural fields. Using potential of satellite imagery taken over time along with remote sensing techniques, makes it possible to determine salinity changes at regional scales. This study deals with monitoring salinity changes and trend of the expansion in different land cover types of Bakhtegan Salt Lake district during the last two decades using multi-temporal Landsat images. For this purpose, per-pixel trend analysis of soil salinity during years 2000 to 2016 was performed and slope index maps of the best salinity indicators were generated for each pixel in the scene. The results of this study revealed that vegetation indices (GDVI and EVI) and also salinity indices (SI-1 and SI-3) have great potential to assess soil salinity trends in vegetation and bare soil lands respectively due to more sensitivity to salt features over years of study. In addition, images of May had the best performance to highlight changes in pixels among different months of the year. A comparative analysis of different slope index maps shows that more than 76% of vegetated areas have experienced negative trends during 17 years, of which about 34% are moderately and highly saline. This percent is increased to 92% for bare soil lands and 29% of salt affected soils had severe salinization. It can be concluded that the areas, which are close to the lake, are more affected by salinity and salts from the lake were brought into the soil which will lead to loss of soil productivity ultimately.

    While it has been reported that the prevalence of mental illness is higher in homeless people than in the national population, few studies have investigated the prevalence of intellectual and developmental disability among the homeless. In this study, we conducted a survey to comprehensively assess these mental problems among homeless people in Nagoya, Japan. The subjects were 18 homeless men. Mental illness was diagnosed with semi-structured interviews conducted by psychiatrists. We used the Wechsler Adult Intelligence Scale III to diagnose intellectual disability. Discrepancies between Wechsler Adult Intelligence Scale III subtest scores were used as criteria for developmental disability. Eleven of the 18 participants were diagnosed with mental illness: six with mood disorder, two with psychotic disorder, and six with alcohol problems. The mean IQ of all subjects was 83.4 ± 27.4. The 95% confidence interval (CI) was 96.2-69.1. Seven participants were found to have intellectual disability. Three men showed discrepancies of more than 10 between subtest scores, and all of them were diagnosed with a mental illness. We divided the participants into four groups: those with mental illness only; those with intellectual disability only; those with both problems; and those without diagnosis. The men with intellectual disability only were significantly younger and had been homeless since a younger age than the other groups. Participants diagnosed with a mental illness had been homeless for longer than those without mental health problems. Although the sample size was limited, this study revealed the high prevalence of mental illness and intellectual disability, 61% (95%CI, 35-83%) and 39% (95%CI, 17-64%), respectively, in homeless people in Nagoya, Japan. © 2014 The Authors.

    Full Text Available Abstract Background Length of stay (LOS is an important indicator of efficiency for inpatient care but it does not achieve an adequate performance if it is not adjusted for the case mix of the patients hospitalized during the period considered. After two similar studies for Internal Medicine and Surgery respectively, the aims of the present study were to search for Length of Stay (LOS predictors in an acute psychiatric department and to assess the performance of the difference: observed-predicted length of stay, as an indicator of inpatient care inefficiencies. Methods Retrospective case-series of patients discharged during 1999 from the Psychiatric Department from General Hospital "Hermanos Ameijeiras" in Havana, Cuba. The 374 eligible medical records were randomly split into two groups of 187 each. We derived the function for estimating the predicted LOS within the first group. Possible predictors were: age; sex; place of residence; diagnosis, use of electroconvulsive therapy; co morbidities; symptoms at admission, medications, marital status, and response to treatment. LOS was the dependent variable. A thorough exam of the patients' records was the basis to assess the capacity of the function for detecting inefficiency problems, within the second group. Results The function explained 37% of LOS variation. The strongest influence on LOS came from: age (p = 0.002, response to treatment (p Conclusions This study demonstrates the importance of possible predictors of LOS, in an acute care Psychiatric department. The proposed indicator can be readily used to detect inefficiencies.

    2012-01-01

    Full Text Available Altered passive eruption/gummy smile is a common challenge in patients requiring aesthetic treatment. A specific surgical protocol was designed and tested in patients with altered passive eruption. Standardized preoperative X-rays were used to assess crown length at baseline and to place submarginal incisions. Osseous respective therapy was performed to achieve biological width. Clinical outcomes were recorded 6 months after surgery. Eleven patients with a total of 58 teeth were treated with flap surgery and osseous resective therapy at upper anterior natural teeth. At the last followup, a significant and stable improvement of crown length was obtained when compared to the baseline (P<0.0001. All patients rated as satisfactory in the final outcomes (final VAS value = 86.6. In conclusion, this study showed that periodontal plastic surgery including osseous resection leads to predictable outcomes in the treatment of altered passive eruption/gummy smile: A careful preoperative planning avoids unpleasant complications and enhances postsurgical stability of the gingival margin.

    Full Text Available The purpose of this study was to clarify the safety and feasibility of a 6-day protocol of bilateral repetitive transcranial magnetic stimulation (rTMS combined with intensive swallowing rehabilitation for chronic poststroke dysphagia. In-hospital treatment was provided to 4 poststroke patients (age at treatment: 56-80 years; interval between onset of stroke and treatment: 24-37 months with dysphagia. Over 6 consecutive days, each patient received 10 sessions of rTMS at 3 Hz applied to the pharyngeal motor cortex bilaterally, followed by 20 min of intensive swallowing rehabilitation exercise. The swallowing function was evaluated by the Penetration Aspiration Scale (PAS, Modified Mann Assessment of Swallowing Ability (MMASA, Functional Oral Intake Scale (FOIS, laryngeal elevation delay time (LEDT and Repetitive Saliva-Swallowing Test (RSST on admission and at discharge. All patients completed the 6-day treatment protocol and none showed any adverse reactions throughout the treatment. The combination treatment improved laryngeal elevation delay time in all patients. Our proposed protocol of rTMS plus swallowing rehabilitation exercise seems to be safe and feasible for chronic stroke dysphagia, although its efficacy needs to be confirmed in a large number of patients.

    For understanding water and solute transport processes, knowledge about the respective hydraulic properties is necessary. Commonly, hydraulic parameters are estimated via pedo-transfer functions using soil texture data to avoid cost-intensive measurements of hydraulic parameters in the laboratory. Therefore, current soil texture information is only available at a coarse spatial resolution of 250 to 1000 m. Here, a method is presented to derive high-resolution (15 m) spatial topsoil texture patterns for the meso-scale Attert catchment (Luxembourg, 288 km2) from 28 images of ASTER (advanced spaceborne thermal emission and reflection radiometer) thermal remote sensing. A principle component analysis of the images reveals the most dominant thermal patterns (principle components, PCs) that are related to 212 fractional soil texture samples. Within a multiple linear regression framework, distributed soil texture information is estimated and related uncertainties are assessed. An overall root mean squared error (RMSE) of 12.7 percentage points (pp) lies well within and even below the range of recent studies on soil texture estimation, while requiring sparser sample setups and a less diverse set of basic spatial input. This approach will improve the generation of spatially distributed topsoil maps, particularly for hydrologic modeling purposes, and will expand the usage of thermal remote sensing products.

    The use of autogenous block grafts harvested from intraoral donor sites has proven to be effective for the reconstruction of horizontal bone defects. The objective of this study was to analyze implant success and the rate of block graft resorption 10 years after ridge augmentation to elucidate contributing factors influencing graft maintenance. A staged horizontal block graft augmentation was performed in 52 implant sites exhibiting severe horizontal bone atrophy using autogenous block grafts protected by DBBM and collagen membranes. The crest width was assessed intraoperatively at surgery and at re-entry after 6 months. At the 10 year reexamination clinical and radiographic parameters were assessed using cone beam computed tomography. The 10-year implant success rate amounted to 98.1%, with minimal peri-implant bone loss (-0.17 mm for the maxilla, -0.09 mm for the mandible). The surface resorption rate after 10 years was 7.7% (0.38 mm). Grafts originating from the chin demonstrated significantly better graft maintenance at 10 years compared to retromolar grafts. Recipient site and age had no significant impact on graft resorption, whereas females showed more bone loss at the 10-year examination. Lateral ridge augmentation using autogenous block grafts and guided bone regeneration demonstrated a favorable success rate of 98.1% with minimal block graft resorption of 7.7% after 10 years. Modulating factors were origin of the graft and gender. © 2016 Wiley Periodicals, Inc.

    Lake Urmia is one of the most important ecosystems of the country which is on the verge of elimination. Many factors contribute to this crisis among them is the precipitation, paly important roll. Precipitation has many forms one of them is in the form of snow. The snow on Sahand Mountain is one of the main and important sources of the Lake Urmia's water. Snow Depth (SD) is vital parameters for estimating water balance for future year. In this regards, this study is focused on SD parameter using Special Sensor Microwave/Imager (SSM/I) instruments on board the Defence Meteorological Satellite Program (DMSP) F16. The usual statistical methods for retrieving SD include linear and non-linear ones. These methods used least square procedure to estimate SD model. Recently, kernel base methods widely used for modelling statistical problem. From these methods, the support vector regression (SVR) is achieved the high performance for modelling the statistical problem. Examination of the obtained data shows the existence of outlier in them. For omitting these outliers, wavelet denoising method is applied. After the omission of the outliers it is needed to select the optimum bands and parameters for SVR. To overcome these issues, feature selection methods have shown a direct effect on improving the regression performance. We used genetic algorithm (GA) for selecting suitable features of the SSMI bands in order to estimate SD model. The results for the training and testing data in Sahand mountain is [R²_TEST=0.9049 and RMSE= 6.9654] that show the high SVR performance.

    The purpose of this study was to evaluate the effectiveness of a treatment for patients with cervicogenic dizziness that consisted of therapeutic education and exercises. The Dizziness Handicap Inventory and Neck Disability Index were used. Secondary outcomes included range of motion, postural control, and psychological variables. Seven patients (two males and five females) aged 38.43±14.10 with cervicogenic dizziness were included. All the participants received eight treatment sessions. The treatment was performed twice a week during a four weeks period. Outcome measures included a questionnaire (demographic data, body chart, and questions about pain) and self-reported disability, pain, and psychological variables. Subjects were examined for cervical range of motion and postural control. All of these variables were assessed pre- and postintervention. Participants received eight sessions of therapeutic education patient and therapeutic exercise. The majority of participants showed an improvement in catastrophism (mean change, 11.57±7.13; 95% confidence interval [CI], 4.96-18.17; d=1.60), neck disability (mean change, 5.14±2.27.28; 95% CI, 3.04-7.24; d=1.32), and dizziness disability (mean change, 9.71±6.96; 95% CI, 3.26-16.15; d=1.01). Patients also showed improved range of motion in the right and left side. Therapeutic patient education in combination with therapeutic exercise was an effective treatment. Future research should investigate the efficacy of therapeutic patient education and exercise with larger sample sizes of patients with cervicogenic dizziness.

    A reduction of hemispatial neglect due to stroke has been associated with activation of the contralesional hand in the contralesional hemispace. Robot-assisted upper limb training was found to effectively improve paretic arm function in stroke patients. To date no proof of concept of robot-assisted hemispatial neglect therapy has been reported in literature. This study aimed to determine whether robot-assisted left (contralesional) hand activation alone could lead to an improvement in hemispatial neglect following stroke. Three stroke patients with right brain injury underwent a 2-week training program of robotic left hand activation with the Gloreha® hand rehabilitation glove, which provides repetitive, passive mobilization of the fingers. Outcomes were assessed using the Line Crossing test, the Bells test, the Sentence Reading test, the Saccadic Training, the Sustained Attention to Response Task, and the Purdue Pegboard test. Changes were observed after treatment as follows. Line Crossing test: all patients showed improved performance (6.7%, 89.5% and 80% increase in lines crossed) with two patients reaching normal performance levels. Bells test: one patient improved performance (50% increase), while one patient showed no change and one patient declined (-10.3% change); no patient reached normal performance levels. Sentence Reading test: all patients showed improved performance (800%, 57.1% and 42.9% increase in number of sentences read) with no patient reaching normal performance level. Saccadic Training: all patients showed improved performance (-62.8%, -15.5% and -9.7% change of the left hemifield reaction time). Sustained Attention to Response Task: all patients showed improved performance (-20.5%, -5.8% and -10% change of the reaction time) with two patients reducing incorrect responses (-42.9% and -73.3%) and one patient increasing them (9.1%). Purdue Pegboard test: all patients showed improved performance (100%, 27.3% and 75% change in the left

    Case series summary A retrospective multicentre case series of feline primary erythrocytosis (PE) was evaluated. The aim was to gain better understanding of disease presentation and progression to guide management and prognostication. Case records were assessed for evidence of increased packed cell volume (PCV; >48%), sufficient investigation to rule out relative and secondary erythrocytosis, and follow-up data for at least 12 months or until death. Eighteen cats were included in the case series. No significant trends in signalment were noted. Seizures and mentation changes were the most common presenting signs (both n = 10). Median PCV was 70% (median total protein concentration of 76 g/l) with no other consistent haematological changes. Sixteen cats survived to discharge. Phlebotomy was performed initially in 15/16 surviving animals and performed after discharge in 10/16. Hydroxyurea was the most common adjunctive therapy, used in 10/16 cats. Of the 16 patients surviving to discharge, 14 patients were still alive at the conclusion of the study (survival time >17 months post-discharge), with the two non-survivors having lived for 5 years or more after diagnosis. PCV, when stabilised, did not correlate with resolution of clinical signs. Relevance and novel information In contrast to perceptions, feline PE was generally well managed via a combination of phlebotomy and medical therapy, with evidence of prolonged survival times. The use of hydroxyurea enabled cessation or repeat phlebotomies.

    Biliary atresia is a progressive disease presenting with jaundice, and is the most common indication for liver transplantation in the pediatric population. Prenatal series have yielded conflicting results concerning a possible association between BA and prenatal nonvisualization of the gallbladder. This retrospective case series was performed to assess the association between biliary atresia, prenatal nonvisualization of the gallbladder and other sonographic signs. We identified biliary atresia patients who underwent a Kasai procedure by a single pediatric surgeon and/or follow up by a single pediatric gastroenterologist. Axial plane images and/or video recordings were scrutinized for sonographic signs of biliary atresia on the second trimester anomaly scan. Proportion of biliary atresia cases with prenatal sonographic signs. Twenty five charts of children with biliary and high quality prenatal images were retrieved. 6/25 (24%) of cases analyzed had prenatal nonvisualization of the gallbladder or a small gallbladder on the prenatal scan. Two cases had biliary atresia splenic malformation syndrome. None of the cases had additional sonographic markers of biliary atresia. Our study suggests that in addition to the well-established embryonic and cystic forms, an additional type can be suspected prenatally, which is characterized by prenatal nonvisualization of the gallbladder in the second trimester. This provides additional evidence that some cases of BA are of fetal rather than perinatal onset and may have important implications for prenatal diagnosis, for counseling and for research of the disease's etiology and pathophysiology.

    Full Text Available Introduction. Sentinel lymph node biopsy in prophylactic mastectomy is controversial. It avoids lymphadenectomy in occult carcinoma but is associated with increased morbidity. Women with BRCA mutations have a higher incidence of occult carcinoma and our objective was to assess the clinical utility of sentinel lymph node biopsy when these women undergo prophylactic mastectomy. Materials and Methods. Seven-year retrospective consecutive case-series study of women, with a BRCA deleterious mutation, admitted to prophylactic mastectomy, at our center. Breast MRI < 6 months before surgery was routine, unless contraindicated. Results. Fifty-seven patients (43% BRCA1; 57% BRCA2 underwent 80 prophylactic mastectomies. 72% of patients had had breast cancer treated before prophylactic mastectomy or synchronously to it. The occult carcinoma incidence was 5%, and half of the cases were invasive. SLNB was performed in 19% of the prophylactic mastectomies; none of these had tumor invasion. Women with invasive carcinoma who had not undergone sentinel lymph node biopsy were followed closely with axillary ultrasound. The median follow-up was 37 months, with no local recurrence; 1 patient died of primary tumor systemic relapse. Conclusions. Our data do not support this procedure for routine (in agreement with previous literature, in this high risk for occult carcinoma population.

    Full Text Available Background. Aging is frequently accompanied by chronic diseases; as a consequence, older people are often exposed to polypharmacy that has been associated with negative health-consequences. The aim of this study is to conduct a systematic review of the literature reporting on the effectiveness of different approaches to reduce polypharmacy in the elderly. Methods. We conducted a comprehensive literature search of MEDLINE, Scopus and ISI Web of Knowledge databases. Eligible studies were case-series reporting outcomes of interventions aimed at reducing polypharmacy and its consequences in the elderly. A quality appraisal of the studies included was performed. Results. Nineteen studies were included, of which six conducted in community setting, seven in hospital setting, and six in nursing homes. Seventeen of them were judged as moderate quality, and two of them as poor quality. The majority of the interventions were carried out by pharmacists, alone (35% or with other professionals (40%. Interventions consisted in pharmacotherapy reviews based on various tools and software; in some cases educational interventions were performed for review-performers and patients. Studies conducted in community-setting provided also a feedback to primary care physician. The outcomes included five categories: therapy’s characteristics (e.g. number of drugs, appropriate prescriptions, quality of life, health-related outcomes, costs, healthcare services’ utilization. Therapy-related outcomes were those more affected by all types of interventions. Conclusion. Interventions aimed at reviewing patients’ therapy are effective in optimizing the use of drugs, and could be considered also  in improving quality of life, healthcare costs, services’ utilization, and health-related outcomes.

    In primary health care systems where member's turnover is relatively low, the question, whether investment in quality of care improvement can make a business case, or is cost effective, has not been fully answered.The objectives of this study were: (1) to investigate the relationship between improvement in selected measures of diabetes (type 2) care and patients' health outcomes; and (2) to estimate the association between improvement in performance and direct medical costs. A time series study with three quality indicators - Hemoglobin A1c (HbA1c) testing, HbA1C and LDL- cholesterol (LDL-C) control - which were analyzed in patients with diabetes, insured by a large health fund. Health outcomes measures used: hospitalization days, Emergency Department (ED) visits and mortality. Poisson, GEE and Cox regression models were employed. Covariates: age, gender and socio-economic rank. 96,553 adult (age >18) patients with diabetes were analyzed. The performance of the study indicators, significantly and steadily improved during the study period (2003-2009). Poor HbA1C (>9%) and inappropriate LDL-C control (>100 mg/dl) were significantly associated with number of hospitalization days. ED visits did not achieve statistical significance. Improvement in HbA1C control was associated with an annual average of 2% reduction in hospitalization days, leading to substantial reduction in tertiary costs. The Hazard ratio for mortality, associated with poor HbA1C and LDL-C, control was 1.78 and 1.17, respectively. Our study demonstrates the effect of continuous improvement in quality care indicators, on health outcomes and resource utilization, among patients with diabetes. These findings support the business case for quality, especially in healthcare systems with relatively low enrollee turnover, where providers, in the long term, could "harvest" their investments in improving quality.

    Generalized gingival enlargement is characterized by massive and exuberant gingival overgrowth that poses social, aesthetic, phonetic and functional problems for the patient. Therefore, it requires meticulous management. Objective: To describe the surgical management of generalized gingival enlargement by electrosurgical excision of patients presenting to a tertiary care centre. Study Design: Case series. Materials and Methods: The study was conducted at the Department of Oral and Maxillofacial Surgery, de'Montmorency College of Dentistry, Lahore, from January 2010 to December 2012. A total of sixteen patients were operated by using electrosurgical approach under general anaesthesia for surgical excision of generalized gingival enlargement. Results: All of the sixteen patients, 11 males and 5 females, showed excellent healing postoperatively without any recurrent gingival overgrowth. Discussion: To the best of our knowledge, the current study presents the largest case series of generalized gingival enlargement. Most of these cases were with massive disease due to lack of information of the study population about their disease, delay in referral by the general dental practitioners, painless and innocent nature of the problem. Early referral of such patients to tertiary care centers can prevent the patients from social and psychological embarrassment. Conclusion: Electrosurgical excision is an excellent surgical technique for management of generalized gingival enlargement. Moreover, cross comparative studies are required to establish some diagnostic and therapeutic standards for such patients. (author)

    Neonatal arrhythmias (NAs) are defined as abnormal heart rates in the neonatal period. They may occur as a result of various cardiovascular, systemic and metabolic problems. A retrospective chart review was performed on newborns who were diagnosed with NA during hospitalization in a neonatal intensive care unit (NICU), or who were admitted to the NICU because of an arrhythmia diagnosis in two NICUs in Turkey from May 2011 to June 2013. Seventeen neonates with arrhythmias were identified. The incidence of NA was 0.4% and 0.3% in the two NICUs, and was 0.37% in the study population as a whole. Mean gestational age was 37 (29-40) weeks. Nine of the infants (53%) were diagnosed with fetal arrhythmia (FA) during the last week of gestation. The distribution of NA types was as follows: six (35%) supraventricular tachycardia (SVT), six (35%) premature atrial contractions (PACs), two (11%) premature ventricular contractions (PVCs), two (11%) multiple arrhythmias such as SVT + PAC and AV block + PVC, and one (5%) AV block. Wolff-Parkinson-White syndrome was present in one patient. An association of NA with congenital heart malformations was identified in five cases. Cardiac arrhythmias are important causes of infant morbidity, and an occasional cause of infant mortality if undiagnosed and untreated. It is important for the physician to be aware of the etiology, development and natural history of arrhythmias in the fetal and neonatal period.

    Full Text Available BACKGROUND: Granulomatous lobular mastitis (GLM is an inflammatory disease of the breast, which can mimic breast cancer in clinical and radiological findings. We conducted the present study in order to determine the diagnostic and other important aspects of this disease. METHODS: In this study, we reviewed the records of 38 patients with granulomatous lobular mastitis in order to describe the clinical, imaging, laboratory, pathologic, and treatment aspects of this disease. RESULTS: All of the patients’ ages were in the range of 22-62 years (mean age: 42 years. All of them had children, history of oral contraceptive pill (OCP usage, antibiotic therapy and mammoplasty. In physical examination, dimpling, edema, inflammation, ulcer, abscess, and firm mass were detected. Size of masses was in the range of 2 × 2 to 8 × 6 cm and their location, in most cases, was in the superior lateral quadrant or central region. In Ultrasonography, a hypoechoic fibroglandular mass and collection, and in pathologic findings, granulomatous reaction was reported. These patients were treated by antibiotics, corticosteroids, and surgery. CONCLUSIONS: GLM is a chronic inflammatory lesion of the breast which can mimic breast cancer. A history of child bearing, lactation, and OCP drug usage have suspicious roles in the formation of GLM. The most common clinical sign in these patients is a painful mass in the breast. We uncovered that clinical and radiological findings are not specific and sufficient for diagnosis of GLM. Therefore, for better diagnosis of this disease, usage of core, incisional, or excisional biopsy are recommended.

    Since the 1990s, self-controlled designs including self-controlled case series (SCCS) studies have been occasionally used in post-marketing evaluation of drug or vaccine safety. An SCCS study was tentatively applied to evaluate the relationship between oseltamivir use and abnormal behavior Type A (serious abnormal behavior potentially leading to an accident or harm to another person) in influenza patients. From the original prospective cohort study with approximately 10,000 Japanese children and adolescents with influenza (aged collaborating hospitals/clinics were analyzed. We hypothesized four combination patterns of the effect period (i.e., the period that effect of oseltamivir on occurrence of abnormal behavior Type A is likely) and the control period. Mantel-Haenszel rate ratio (M-H RR) and its 95% confidence interval (CI) were calculated as the relative risk estimate. Among 28 subjects in the SCCS study, 24 subjects (86%) were administered oseltamivir and 4 subjects (14%) were not. Abnormal behavior Type A was more likely to occur in the effect period than the control period in every pattern (M-H RR: 1.90-29.1). We observed the highest estimate when the effect period was set between the initial intake of oseltamivir and T max (M-H RR: 29.1, 95% CI: 4.21-201). Abnormal behavior Type A was more likely to develop up to approximately 30 times during the period between the initial intake of oseltamivir and T max . However, this period overlapped with the early period of influenza where high fever was observed. Since useful approaches to control the influence of the natural disease course of influenza were not available in this study, we could not deny the possibility that abnormal behavior was induced by influenza itself. The SCCS study was not an optimal method to evaluate the relationship between oseltamivir use and abnormal behavior. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Context Direct endoscopic visualization of biliopancreatic duct is certainly one of the greatest advances of therapeutic endoscopy. The use of a single-operator cholangioscopy platform (SpyGlass is a promising technique in the evaluation of diseases such as indeterminate biliary stricture and giant choledocholitiasis. This is the first Brazilian case series using this technology. Methods We report a case series of 20 patients in whom SpyGlass was used with diagnostic and therapeutic intention. Results Most patients were female (60% and the median age was 48 years (ranging from 14 to 94. Choledocholitiasis was the most common indication (12/20, and electrohydraulic lithotripsy was applied in eight (66%. Electrohydraulic lithotripsy was successful in seven (87.5% patients. Partial stone fragmentation occurred in one patient with large stone causing stone-choledochal disproportion, which was conducted with biliary plastic stent placement and a second scheduled endoscopic approach in 3 months. In cases of undefined etiology of biliary strictures, it was possible to exclude malignancy due to direct visualization (7/8 or biopsy (1/8. One complication occurred (duodenal perforation after papillary balloon dilation. Conclusion The use of SpyGlass demonstrated the benefits, especially in cases of large bile duct stones and indeterminate biliary strictures. Other potencial improvements such as reduction on radiation exposure should be confirmed in prospective studies.

    Full Text Available INTRODUCTION: Torus palatinus is a specific name to identify exostoses developed in the hard palate along the median palatine suture. Despite of not being a pathological condition, its presence requires attention and knowledge regarding its management. Surgical removal of exostoses is indicated when the patient frequently traumatizes the area of palatine torus during mastication and speech or when it is necessary for the rehabilitation of the upper arcade with complete dentures. OBJECTIVE: The aim of this article is to present three cases of Torus palatinus and to discuss the management of them. CASE REPORT: In the first case, a 57-year-old Caucasian man sought oral rehabilitation of his edentulous maxilla but presented a hard nodules in the hard palate; in the second case, a 40-year-old Caucasian woman was referred for frequent trauma of palatal mucosa during mastication, aesthetic complaint, and discomfort caused by the trauma of her tongue in this area; and in the third case, a 45-year-old Caucasian woman presented with a lesion on the palate that caused difficulty swallowing. When the Torus palatinus was impairing the basic physiological functions of the patients, all cases were surgically treated, improving the patients' quality of life. FINAL CONSIDERATION: The dentist should be properly prepared to choose the best from among the existing surgical approaches for each individual lesion in order to improve the results and avoid possible complications.

    Full Text Available We describe two cases of spontaneous pneumothorax in young healthy adults with no underlying structural lung disease. The onset of pneumothorax was following physical activity including playing musical instruments and blowing of balloons. There is sparse data evaluating the pathophysiology of primary spontaneous pneumothorax in relation to increased mouth pressures. These cases highlight the possible physical effect of valsalva manoeuvre on transpulmonary pressures, and the potential risk of developing pneumothorax in otherwise healthy individuals. This aspect of pneumothorax development is worthy of further exploration, to better elucidate the mechanism and enhance our understanding of this common respiratory presentation.

    Full Text Available Multi-temporal Interferometric Synthetic Aperture Radar (MT-InSAR technique has proven to be a powerful tool for the monitoring of time-series ground deformations along the line-of-sight (LOS direction. However, the one-dimensional (1-D measurements cannot provide comprehensive information for interpreting the related geo-hazards. Recently, a novel method has been proposed to map the three-dimensional (3-D deformation associated with underground fluid flows based on single-track InSAR LOS measurements and the deformation modeling associated with the Green’s function. In this study, the method is extended in temporal domain by exploiting the MT-InSAR measurements, and applied for the first time to investigate the 3-D time series deformation over Sebei gas field in Qinghai, Northwest China with 37 Sentinel-1 images acquired during October 2014–July 2017. The estimated 3-D time series deformations provide a more complete view of ongoing deformation processes as compared to the 1-D time series deformations or the 3-D deformation velocities, which is of great importance for assessing the possible geohazards. In addition, the extended method allows for the retrieval of time series of fluid volume changes due to the gas extraction in the Sebei field, which agrees well with those from the PetroChina Qinghai Oilfield Company Yearbooks (PQOCYs. This provides a new way to study the variations of subsurface fluids at unprecedented resolution.

    Full Text Available Pur po se: To evaluate the etiological factors, diagnosis, follow-up and treatment procedures in cases of orbital cellulitis. Ma te ri al and Met hod: A retrospective review was performed on medical records of patients with orbital cellulitis treated between 2009 and 2011 in our clinic. The patients were studied for age, ophthalmologic examination features, laboratory and radiology results, treatment modalities and the response to these treatments. Re sults: Eleven patients (7 male, 4 female having an average age of 9.7 years (6 months-25 years participated in the study. All patients had eyelid oedema, hyperemia and ocular pain; with chemosis in 3, gaze restriction in 6, relative afferent pupillary defect and proptosis in 4 cases. Orbital cellulitis was observed to occur secondary to paranasal sinusitis in 10 patients (90.9% and 1 patient had only history of superior respiratory tract infection. Sinus infection was localized in ethmoid and maxillary sinuses in all except one case. Laboratory tests showed leukocytosis in 8 patients. Surgical drainage was performed in 7 of 8 patients with abscess formation observed with radiological imaging. The remainder of the patients were followed with sole medical treatment. All patients recovered without any vision loss or life-threatening complication. Dis cus si on: Orbital cellulitis cases must be followed with radiologic imaging for any complication that may occur and patients with abscess should be evaluated for surgical drainage besides antimicrobial treatment.(Turk J Ophthalmol 2012; 42: 284-7

    Full Text Available Abstract Background Encephalomeningocele, especially in the frontoethmoidal region, is a form of neural tube defect which affects patients in Southeast Asia more commonly than in Western countries. Its underlying cause is not known but teratogenic environmental agents are suspected. However, nutritional deficiency, as in spina bifida, cannot be excluded. Methods This study reports 21 cases of meningocele (without brain tissue in the lesion and encephalomeningocele (with brain tissue that were admitted to our hospital for surgical corrections in the period of ten years, from 1990 to 1999. Clinicopathological findings, as well as occupations of family members and prenatal exposures to infectious agents or chemicals were reviewed and analyzed. Results The most commonly involved area was the frontoethmoidal region, found in 20 cases. The combined pattern between nasoethmoidal and nasoorbital defects was found most frequently (11 from 21 cases and had more associated abnormalities. Encephalomeningocele had more related abnormalities than meningocele with proportions of 0.6 and 0.3, respectively. Conclusions Here, we confirmed that genetic defects are not likely to be the single primary cause of this malformation. However, we could not draw any conclusions on etiologic agents. We suggest that case control studies and further investigation on the role of nutritional deficiencies, especially folic acid, in the pathogenesis of encephalomeningocele are necessary to clarify the underlying mechanisms.

    Full Text Available Abstract Background Few studies have described patients with foregut dysmotility in inflammatory bowel disease. The aim of this case series was to evaluate clinical characteristics of 5 patients with inflammatory bowel disease and symptoms and signs of upper gut dysmotility. Case presentations We describe a series of four patients with Crohn's disease and one with indeterminate colitis who presented with severe symptoms and signs of gastroparesis. We reviewed medical records of all cases. Gastric emptying of a solid meal was assessed by scintigraphy. Small bowel enteroclysis, gastroduodenoscopy and colonoscopy with biopsies were performed to estimate the activity of the disease and to exclude organic obstruction. None of the patients had any signs of active inflammation or stricture. All of the patients had markedly delayed gastric emptying with a mean t 1/2 of 234 minutes (range 110–380 minutes; normal values 54–94 minutes. Conclusion Clinicians should consider impaired gastric emptying when evaluating patients with Crohn's disease and severe symptoms of upper gut dysmotility, which cannot be attributed to active inflammation or organic obstruction of the digestive tract. Symptoms in these patients are refractory to various therapeutic interventions including tube feeding and gastric surgery.

    The incisions during orthognathic surgery are classically performed with conventional scalpel or electrocautery. Considering that the high-power diode laser surgery may provide advantages when compared to conventional incision techniques, the current study aimed to present a prospective case series of patients submitted to circumvestibular incision for Le Fort I osteotomy. Ten patients with dentofacial deformities who underwent to rapid assisted maxillary expansion or bimaxillary orthognathic surgery were enrolled in the study. All incisions were performed by a single surgeon using an 808-nm diode laser, with an optical fiber of 600 μm, at a power of 2.5 W, in a continuous-wave mode. The performance of the incision was evaluated by incision velocity, bleeding, edema, secondary infection, clinical healing, and pain. The velocity of the incision ranged from 0.10 to 0.20 mm/s (mean 0.13 ± 0.03 mm/s). Considering bleeding during the soft tissue incision, all surgeries were classified as absent bleeding. All patients presented a clinical healing of the surgical wound in a period that range from 3 to 5 weeks and experienced swelling during the follow-up period. On average, approximately 50% of the swelling had resolved after the third postoperative week, and 28.8% of swelling remained after 2 months after the surgery. The pain decreased after 2 and 3 days, and 90.0% of the patients reported no pain after 7 postoperative days. High-power diode laser is effective and safety during circumvestibular incisions for Le Fort I osteotomy in orthognathic surgery decreasing bleeding, surgery time, pain, and edema after orthognathic surgery.

    The objective of this work is to study the spatial patterns of vegetation activity over spain and its temporal variability throughout the period 1989-2002. A multi-resolution analysis (MRA) bases on the wavelet transform has been implemented on NDVI time series from the MEDOKADS database. The MRA decomposes the original signal as a sum of series associated with temporal scales. Specifically, the intra-annual series is processed to define several key features in relation with the vegetation penology. In contras, the inter-annual components of the signal is used to detect trends by means of a Mann-Kendall test and map the magnitude of the land-cover change. Finally, a comprehensive identification of the areas presenting a negative value of the magnitude of change is carried out to select those linked to land degradation processes. Results show a major presence of these areas the Southeast of Spain. (Author) 5 refs.

    Tropical diabetic hand syndrome is a term used to describe diabetes complication of the hand affecting people in the tropics. It consists of localized cellulitis with variable swelling and ulceration of the hands, progressive, fulminant hand sepsis and gangrene in extreme cases. This syndrome is not well-recognized and is therefore less frequently reported. The authors describe three different female patients who were known diabetics of varying duration presenting with this syndrome at our tertiary health center and who were successfully managed by both the surgical and medical units. The need for early diagnosis and aggressive management is emphasized.

    Tuberculosis remains an infectious disease with a high prevalence worldwide and represents a major public health issue. Although venous thromboembolism is a rare complication of this disease, it may be a potentially life-threatening event. We report two cases of severe pulmonary tuberculosis associated with venous thromboembolism. A 38 year-old caucasian male that had a thromboembolic event as an unsual presentation form of tuberculosis and a 51 year-old caucasian male that developed deep venous thrombosis later in the course of the disease. An association between inflamation induced by tuberculosis and a hypercoagulable state has been described. Therefore, the occurence of deep venous thrombosis or pulmonary embolic episods, should be considered in patients with tuberculosis particulary during the first weeks of treatment. The physician's awarness of these phenomena is important to an early diagnostic suspicion and prompt treatment in order to prevent fatal outcomes.

We therefore present three cases of accidental decannulation of tracheostomy tubes in order to report our experiences in the management of the condition. Accidental decannulation occurs both in hospitalized and patient on home care of their tracheostomy tubes. Reduction in neck circumference due to weight loss predisposes to accidental decannulation, which could be prevented by suturing the flange to the skin.

    Cutaneous leiomyomas are benign smooth muscle tumors that comprise three distinct types such as piloleimyoma, angioleiomyoma, and genital leiomyoma. The objective of this study was to report a series of cases seen in last 8 years in a tertiary care hospital in north India and to discuss their clinicopathologic findings. Paraffin-embedded blocks of cases reported as cutaneous leiomyoma from 1999 to 2007 were retrieved from the Institute of Pathology, New Delhi, and their clinical parameters were noted. Their histopathological features were reviewed on hematoxylin-eosin stained slides. Immunohistochemistry was performed where necessary. Twenty-seven cases of piloleiomyoma, three cases of angioleiomyoma, five breast leiomyomas, and two scrotal leiomyomas were seen in patients ranging from 21 to 65 years of age, with an average of 38.2 years at presentation. There was a male predominance with 26 males and 11 females (M:F = 2.2:1). Solitary lesions (n = 21) were more common than multiple ( n = 16). The trunk and upper limbs were involved most commonly, comprising 23 of 37 (62.2%) cases. This was followed by lower limb, face, breast, and scrotum. Cutaneous leiomyomas are rare lesions and form an important clinical differential diagnosis of painful papulonodules. These must be biopsied in order to differentiate them from other spindle cell lesions.

    This report details one of three experiments performed during FY 2007 for the NASA RPC (Rapid Prototyping Capability) at Stennis Space Center. This RPC experiment assesses the potential of VIIRS (Visible/Infrared Imager/Radiometer Suite) and MODIS (Moderate Resolution Imaging Spectroradiometer) data for detecting and monitoring forest defoliation from the non-native Eurasian gypsy moth (Lymantria dispar). The intent of the RPC experiment was to assess the degree to which VIIRS data can provide forest disturbance monitoring information as an input to a forest threat EWS (Early Warning System) as compared to the level of information that can be obtained from MODIS data. The USDA Forest Service (USFS) plans to use MODIS products for generating broad-scaled, regional monitoring products as input to an EWS for forest health threat assessment. NASA SSC is helping the USFS to evaluate and integrate currently available satellite remote sensing technologies and data products for the EWS, including the use of MODIS products for regional monitoring of forest disturbance. Gypsy moth defoliation of the mid-Appalachian highland region was selected as a case study. Gypsy moth is one of eight major forest insect threats listed in the Healthy Forest Restoration Act (HFRA) of 2003; the gypsy moth threatens eastern U.S. hardwood forests, which are also a concern highlighted in the HFRA of 2003. This region was selected for the project because extensive gypsy moth defoliation occurred there over multiple years during the MODIS operational period. This RPC experiment is relevant to several nationally important mapping applications, including agricultural efficiency, coastal management, ecological forecasting, disaster management, and carbon management. In this experiment, MODIS data and VIIRS data simulated from MODIS were assessed for their ability to contribute broad, regional geospatial information on gypsy moth defoliation.

    Treatment for primary mediastinal lymphoma generally involves chemotherapy and radiotherapy, and treatment regimens depend on histologic subtypes of lymphoma. The histologic subtype of lymphoma is mostly determined by computed tomography (CT)-guided core-needle biopsy or surgical procedures, including thoracotomy, thoracoscopy and mediastinoscopy. We describe the clinicopathologic features and diagnostic procedures of 8 cases of primary mediastinal lymphoma. The male-to-female ratio was 1:1, and median age at diagnosis was 27 years. The median size of the primary mediastinal tumor on CT was 8.5 cm. Five patients were diagnosed by CT-guided core-needle biopsy, 1 by open biopsy and 2 by surgery. Three patients were diagnosed with nodular sclerosis Hodgkin lymphoma, 3 with mediastinal diffuse large B-cell lymphoma, 1 with precursor T-lymphoblastic leukemia/lymphoma and 1 with thymic extranodal marginal zone B-cell lymphoma. According to their histological subtypes, 5 patients were treated with chemoradiotherapy, 2 patients with chemotherapy and 1 patient of thymic extranodal marginal zone B-cell lymphoma with surgery alone. All patients survived in the median follow-up of 34.5 months. Appropriate biopsy procedure should be performed in patients with suspected mediastinal lymphoma.

    Full Text Available Abstract Background The restoration of walking ability is the main goal of post-stroke lower limb rehabilitation and different studies suggest that pedaling may have a positive effect on locomotion. The aim of this study was to explore the feasibility of a biofeedback pedaling treatment and its effects on cycling and walking ability in chronic stroke patients. A case series study was designed and participants were recruited based on a gait pattern classification of a population of 153 chronic stroke patients. Methods In order to optimize participants selection, a k-means cluster analysis was performed to subgroup homogenous gait patterns in terms of gait speed and symmetry. The training consisted of a 2-week treatment of 6 sessions. A visual biofeedback helped the subjects in maintaining a symmetrical contribution of the two legs during pedaling. Participants were assessed before, after training and at follow-up visits (one week after treatment. Outcome measures were the unbalance during a pedaling test, and the temporal, spatial, and symmetry parameters during gait analysis. Results and discussion Three clusters, mainly differing in terms of gait speed, were identified and participants, representative of each cluster, were selected. An intra-subject statistical analysis (ANOVA showed that all patients significantly decreased the pedaling unbalance after treatment and maintained significant improvements with respect to baseline at follow-up. The 2-week treatment induced some modifications in the gait pattern of two patients: one, the most impaired, significantly improved mean velocity and increased gait symmetry; the other one reduced significantly the over-compensation of the healthy limb. No benefits were produced in the gait of the last subject who maintained her slow but almost symmetrical pattern. Thus, this study might suggest that the treatment can be beneficial for patients having a very asymmetrical and inefficient gait and for those

    2010-03-01

    Full Text Available Abstract Introduction Pica is an unusual condition where patients develop cravings for non-nutritive substances that can cause significant health risks. We report three patients with pica, two of them showing evolutionary changes associated with pica and the third demonstrating a peculiar nature of pica, which has yet to be reported. Case presentation We describe three patients who presented with symptoms of pica. The first patient is a 36-year-old Caucasian woman who had dysfunctional uterine bleeding associated with daily ingestion of two super-sized cups of ice as iced tea. The second patient is a 62-year-old Caucasian man who presented with bleeding from colonic polyps associated with drinking partially frozen bottled water. Lastly, the third patient, a 37-year-old Hispanic woman, presented with dysfunctional uterine bleeding and habitually chewed rubber bands. All three patients presented with hematological parameters diagnostic for iron deficiency anemia. Conclusion Pica has been practiced for centuries without a clear etiology. We have noticed that the younger community of academic and community physicians are not aware of the importance of complaints related to pica. None of our patients we describe here, as well as their primary care physicians, were aware of the importance of their pica related symptoms. Pica symptoms abated in one of our patients upon iron supplementation, while the other two are currently under treatment as of this writing. We believe pica is an important sign of iron deficiency that should never be ignored, and the craving for any unusual substance should compel clinicians to search for occult blood loss with secondary iron deficiency.

    Posttraumatic stress disorder (PTSD) is a serious health concern. Current evidence-based treatments for PTSD are efficacious; however, they are not appropriate or tolerated by everyone who needs them. Alternative treatment approaches are needed. Shamanic healing is one such therapy that may potentially be beneficial but no systematic research has been conducted on it for PTSD. The objectives of the case series are to (1) develop a structured replicable shamanic treatment plan for veterans with posttraumatic stress disorder (PTSD); (2) collect preliminary data on PTSD-related outcomes, and (3) explore the feasibility and potential for adverse events of the plan. Case series. Clinical. Veterans with PTSD. Shamanic healing. PTSD symptoms, quality of life, and piritual wellness. A semi-structured shamanic healing protocol was created with the following components: rapport building, power animal retrieval, extraction, compassionate spirit release, curse unraveling, soul retrieval, forgiveness/cord-cutting, aspect maturing/soul rematrixing, and divination. Six veterans enrolled in the study (mean age = 49.3 ± 13.1). Qualitative descriptions of the participants, their histories, and effects from the intervention are reported. Preliminary data was collected on PTSD-related outcomes. The protocol was found feasible and acceptable and recommendations for its future use are suggested. Future research is warranted and needed to evaluate the efficacy of shamanic healing as a potential therapy for veterans with PTSD. Copyright © 2017 Elsevier Inc. All rights reserved.

    The purpose of this study is to describe chiropractic treatment of 14 patients who presented with signs and symptoms of temporomandibular joint dysfunction (TMD). This is a retrospective case series of 14 patients, including 13 adults and 1 child. The majority of these patients were undergoing chiropractic care for spine-related conditions when they presented with additional TMD signs and symptoms. They were evaluated and treated with Activator Methods International published protocols relative to the temporomandibular joint before the addition of treatment to the suprahyoid muscles. All pre- and postadjustment assessments were recorded using a numeric pain scale. The resulting average showed a reduction in the patients' pain scores from the initial visit of 8.3 ± 1.6 to the last visit at 1.4 ± 1.1 with an 80.9% ± 15.4% improvement. The average number of visits was 13.6 ± 8.2. All patients selected for this case series showed a reduction of temporomandibular dysfunction symptoms.

    The development of thromboembolism is one of the most common complications of neuroendovascular procedures. Although several small studies have deemed clopidogrel safe and effective in the prevention of intracranial stent thrombosis, ticagrelor has yet to be assessed in this setting. The objective of this study was to retrospectively evaluate the safety and efficacy of ticagrelor in patients undergoing neuroendovascular procedures. A retrospective review of patients receiving ticagrelor following neuroendovascular aneurysm repair. A total of 5 patients undergoing neuroendovascular aneurysm repair received ticagrelor for a median of 5 days while hospitalized. Three patients were treated with stent-assisted coiling, while 2 received pipeline embolization devices. All patients received additional low-dose aspirin therapy. One patient received ticagrelor after experiencing a thrombotic event on clopidogrel, while a second patient was treated with ticagrelor after developing a dermatologic reaction to clopidogrel. Three (60%) patients were successfully treated and discharged on ticagrelor therapy. Two patients experienced cerebrovascular accidents following aneurysm repair while receiving ticagrelor, one of which was potentially due to medication omission. One (20%) patient receiving ticagrelor experienced a small retroperitoneal hematoma; however, ticagrelor therapy was continued without further complication. Therapy with ticagrelor may be a safe and effective treatment option for patients undergoing neuroendovascular aneurysm repair. However, future studies are warranted to substantiate these findings.

    Recent research into positive experiences in caregivers has begun to redress the traditional focus on negative aspects of caregiving experiences. This exploratory study used a cognitive-behavioural approach - namely, the transactional stress model (Lazarus and Folkman, 1984) - to investigate associations between appraisals, coping, and gains over a 6-week period in a small sample (N = 4; case series) design involving stroke caregivers. Analysis involved visual inspection of graphs, supported by descriptive statistics, and co-variation analysis. Participants reported high levels of positive experiences, and these increased over the study period, a previously unreported trend. The study also found individual differences in the interactions between appraisal, coping, and caregiving gain variables, findings explained by the transactional stress model. Implications for clinical practice and future research are addressed.

    Anorexia nervosa (AN) is a serious disorder with associated morbidity and mortality, most commonly diagnosed in females. Existing literature on male anorexia is sparse, and a review of the endocrine effects of AN in males has not previously been published. Our objective is to highlight the clinical characteristics of AN in males as a routinely overlooked cause of multiple endocrinopathies and systemic illness in hospitalized patients. We present 4 cases (2 cases at The Mount Sinai Hospital; 2 cases at Long Island Jewish Hospital) of young men with hormonal dysfunction due to underlying AN. Pertinent de-identified data were collected from a chart review of cases seen on the endocrinology consult service at both hospitals. Institutional Review Board approval was not required for an observational report of the cases presented. Four young men with AN demonstrated evidence of multiple systemic complications from severe caloric and protein malnutrition. Varying degrees of endocrinopathies were present, including hypogonadotropic hypogonadism, hypercortisolemia, and nonthyroidal illness syndrome, resulting in bradycardia, gastroparesis, hypothermia, acute systolic heart failure, and erectile dysfunction. Ages at diagnosis were 20, 24, 23, and 20 years, with mean age 21.75 years. Most of the clinical effects from these endocrinopathies resolved with improved caloric intake and nutrition, although symptoms of hypogonadism persisted. This small case series highlights the importance of AN as a potential cause of multiple endocrinopathies in males. The heterogeneous presentations and varying degrees of clinical manifestations in our cohort emphasize the challenge in diagnosis. Increased awareness of AN in males is vital, as its prevalence is likely underestimated and appropriate diagnosis and treatment can ameliorate the metabolic dysfunction in a majority of cases. Further studies on males with eating disorders are needed to help guide diagnostic and therapeutic decisions.

    2012-02-01

    OBJECTIVES: To establish a clinicopathological profile of malignant otitis externa (MOE) in an Australian tertiary referral institution. STUDY DESIGN: Retrospective cohort outcomes study. METHODS: 24 patients were identified with MOE between January 1998 and July 2007. Patients were classified into Radiological Grades I-IV. Laboratory investigations Including C-reactive protein (CRP), white cell count (WCC), glycosylated haemoglobin (HBA1c) and average glucose level over admission were recorded. RESULTS: Radiological Grade was significantly associated with duration of therapy (rank correlation 0.57, p = 0.004). CRP was a useful indicator confirming disease resolution. Diabetics with MOE had elevated average blood sugar levels during their Hospital admission (p < 0.001) and had poor overall glycaemic control represented by Elevated HBA1c scores (p < 0.001). CONCLUSIONS: Malignant otitis externa is a rare disease, which is best managed in a multidisciplinary team setting. This practical grading system can be used to predict the duration of therapy at time of diagnosis, which enables the efficient utilisation of Hospital resources. Poorly controlled diabetics are more susceptible to developing. MOE than diabetics with satisfactory glycaemic control and may represent a subgroup of more brittle diabetics. CRP combined with appropriate clinical and radiological investigations is useful in assessing disease resolution.

    Hypertension carries a large societal burden. Obesity is known as a risk factor for hypertension. However, little is known as to whether weight loss interventions reduce the risk of hypertension-related adverse events, such as acute care use (emergency department [ED] visit and/or unplanned hospitalization). We used bariatric surgery as an instrument for investigating the effect of large weight reduction on the risk of acute care use for hypertension-related disease in obese adults with hypertension. We performed a self-controlled case series study of obese patients with hypertension who underwent bariatric surgery using population-based ED and inpatient databases that recorded every bariatric surgery, ED visit, and hospitalization in three states (California, Florida, and Nebraska) from 2005 to 2011. The primary outcome was acute care use for hypertension-related disease. We used conditional logistic regression to compare each patient's risk of the outcome event during sequential 12-month periods, using pre-surgery months 13-24 as the reference period. We identified 980 obese patients with hypertension who underwent bariatric surgery. The median age was 48 years (interquartile range, 40-56 years), 74% were female, and 55% were non-Hispanic white. During the reference period, 17.8% (95% confidence interval [CI], 15.4-20.2%) had a primary outcome event. The risk remained unchanged in the subsequent 12-month pre-surgery period (18.2% [95% CI, 15.7-20.6%]; adjusted odds ratio [aOR] 1.02 [95% CI, 0.83-1.27]; P = 0.83). In the first 12-month period after bariatric surgery, the risk significantly decreased (10.5% [8.6-12.4%]; aOR 0.58 [95% CI, 0.45-0.74]; P bariatric surgery (12.9% [95% CI, 10.8-15.0%]; aOR 0.71 [95% CI, 0.57-0.90]; P = 0.005). By contrast, there was no significant reduction in the risk among obese patients who underwent non-bariatric surgery (i.e., cholecystectomy, hysterectomy, spinal fusion, or mastectomy). In this population-based study of

    Only few studies have considered the effects of the combined treatment with onabotulinumtoxinA (BoNT-A) injections and biofeedback (BFB) rehabilitation in the recovery of postparetic facial synkinesis (PPFS). To explore the presence of a persistent improvement in facial function out of the pharmacological effect of BoNT-A in subjects with established PPFS, after repeated sessions of BoNT-A injections combined with an educational facial training program using mirror biofeedback (BFB) exercises. Secondary objective was to investigate the trend of the presumed persistent improvement. Case-series study. Outpatient Clinic of Physical Medicine and Rehabilitation Unit. Twenty-seven patients (22 females; mean age 45±16 years) affected by an established peripheral facial palsy, treated with a minimum of three BoNT-A injections in association with mirror BFB rehabilitation. The interval between consecutive BoNT-A injections was at least five months. At baseline and before every BoNT-A injection+mirror BFB session (when the effect of the previous BoNT-A injection had vanished), patients were assessed with the Italian version of Sunnybrook Facial Grading System (SB). The statistical analysis considered SB composite and partial scores before each treatment session compared to the baseline scores. A significant improvement of the SB composite and partial scores was observed until the fourth session. Considering the "Symmetry of Voluntary Movement" partial score, the main improvement was observed in the muscles of the lower part of the face. In a chronic stage of postparetic facial synkinesis, patients may benefit from a combined therapy with repeated BoNT-A injections and an educational facial training program with mirror BFB exercises, gaining an improvement of the facial function up to the fourth session. This improvement reflects the acquired ability to use facial muscle correctly. It doesn't involve the injected muscles but those trained with mirror biofeedback exercises

    Full Text Available Background: Atypical meningiomas fall into a category World Health Organization Grade II, which have higher local recurrence rates and lower survival rates than their benign counterparts. The aim of this study is to review the outcome of newly diagnosed patients with atypical meningioma after therapy. Methods: We conducted a retrospective review of the medical records of patients having atypical meningiomas who were treated in our hospital between January 2005 and December 2014. Their age, sex, initial presentation, tumor location, tumor size, extent of resection, tumor recurrence or tumor progression, duration of follow-up, adjuvant therapy, and outcome were reviewed. Results: There were 27 consecutive patients (15 male and 12 female having fresh intracranial atypical meningiomas treated in our hospital between January 2005 and December 2014. Their mean age at diagnosis was 60.81 years. Twenty-three patients (85.19% underwent total resection of the tumor, whereas 4 patients (14.81% had partial resection of their tumors during their first time of surgery. Fifteen patients (55.56% had finished adjuvant radiotherapy. Nine patients (33.33% had tumor progression or recurrence during follow-up, and 4 of them were proved to have malignant transformation to anaplastic meningiomas in the following operations. The mean time to tumor progression or recurrence of these nine patients was 17.67 months. Nineteen patients (70.37% had a favorable outcome, 7 patients (25.93% had an unfavorable outcome, and we lost 1 patient (3.7% due to disease progression. Conclusions: Surgery remains the standard treatment to atypical meningioma, and postoperative adjuvant radiotherapy is still controversial especially to those who undergo total surgical resection of the tumors. Our study reveals that early postoperative adjuvant radiotherapy seems to play a role in local control. Atypical meningioma can have malignant transformation to anaplastic meningioma, so aggressive

    Full Text Available Background and Purpose: Occular toxicity is one of the most important complications of Hydroxychloroquine. Not any type of treatment has so far been found and recommended for this disorder. The purpose of this study was to report some characteristics of patients with Hydroxychloroquine Induced Retinopathy.    Materials and Methods: From 107 patients with rheumatoid arthritis (RA and/or systemic lupus erythematosus (SLE during 2013-14 in Sari, Iran, who were selected by a simple sampling method and were referred to hospitals for ophthalmologic examinations, 21 patients were found with HCQ induced retinopathy. The Examination for HCQ-induced maculopathy was performed through fundoscopy, perimetry or optical coherence tomography (OCT, and the physicians had their own discretion based on the examination. Although the patients were examined by different ophthalmologists, all of them were evaluated by the same device (Zeiss cirrus HD OCT4000.USA for OCT, Zeiss Humphrey Field analyzer 2i. USA for visual field, and Topcon. TRC.50Dx. Japan for angiography. Based on the collected data, the characteristics of clinical and ophthalmologic changes were reported, and the data were analysed through Independent Sample t Test and χ2.    Results: 21 patients (19 females with a mean age of 49.86 (±15.6 were evaluated during 4.95 (±4.7 years of therapy. The mean of cumulative dose was calculated to be 313.18±269.8 grams. Based on the findings, hypertension was detected in 5 (23.8% of the patients. Conclusion: In the present study, it was found that HCQ induced retinal toxicity may occur even in recommended doses or for less than 5 years. Other risk factors such as hypertension in addition to the dose or duration of toxicity could also accelerate retinal toxicity.

    Traumatic peripheral nerve palsies in the newborn are uncommon but are a cause of severe anxiety in parents. Erb's palsy, brachial plexus, radial nerve and facial nerve are the common nerves affected. Perinatal injuries are the most frequent cause of traumatic peripheral neuropraxias / nerve palsies. Usually these neuropraxias are self-limited with good recovery with conservative management in majority of cases.Ten neonates with peripheral neuropraxias were included in this retrospective study based on a review of these cases over a period of three and a half years. Their clinical profile, presenting symptoms, predisposing factors and management were analyzed. We encountered five neonates with erb's palsy, three with facial palsy and two had radial nerve affection. Risk factors in our series included large babies, prolonged or difficult labour, instrumental delivery and shoulder dystocia. All cases of peripheral nerve involvement were managed conservatively with physiotherapy. Nine neonates were discharged and showed gradual improvement and one patient unfortunately succumbed due to severe birth asphyxia. Parental counseling and rehabilitation play an important part in management of these cases.

    Full Text Available Reduction mammoplasty is one of the most common procedures performed by plastic surgeons. Surgeons select the technique that best suits each patient based on the surgeon’s experience, specific patient characteristics and requirements. The purpose of this article is to report the complications that occurred in patients who underwent reduction mammoplasty at our institution, and to compare our data to the current literature. We studied the postoperative complications from 82 breast reductions (41 patients, which used superior pedicle (n = 6, inferior pedicle (n = 36, medial pedicle (n = 10 or Thorek (n = 30 techniques. The most common postoperative complications were hematoma (7%, seroma (2.5%, delayed wound healing (14%, partial nipple loss (4.8%, infection (10% and asymmetry (12%. We observed complications in 64% of patients that underwent inferior pedicle breast reduction with an inverted T scar. One possible explanation for this complication rate is that inferior pedicle Wise-pattern mammoplasty is usually performed for breasts with sternal notch-tonipple distances greater than 32 cm, or for symptomatic macromastia, and greater amounts of resected tissue are known to be associated with higher complication rates. Nevertheless, this technique is associated with excellent patient satisfaction. Indeed, complications are quite frequent and may occur even in the most suitable candidates, but do not compromise the final result.

    Seasonal allergic rhinitis (hay fever) is common and can considerably reduce the quality of life of sufferers. Despite the wide everyday application and promising results with homeopathy, scientific evidence of its effectiveness for most ailments is scarce. The assessment of the clinical effectiveness of homeopathic remedies in the alleviation of hay fever symptoms in a typical clinical setting. We performed a clinical observational study of eight patients in the treatment of hay fever symptoms over a two-year period (2012 and 2013) using Measure Yourself Medical Outcome Profile (MYMOP) self-evaluation questionnaires at baseline and again after two weeks and four weeks of homeopathic treatment. The individualized prescription - either a single remedy or multiple remedies - was based on the totality of each patient's symptoms. The average MYMOP scores for the eyes, nose, activity and wellbeing had improved significantly after two and four weeks of homeopathic treatment. The overall average MYMOP profile score at baseline was 3.83 (standard deviation, SD, 0.78). After 14 and 28 days of treatment the average score had fallen to 1.14 (SD, 0.36; PHomeopathy.

    Full Text Available Objective: Neonatal pneumothoraces are associated with high mortality. Prompt recognition to minimize its complications is paramount for ultimate outcome of these babies.Methods: A retrospective case series study was carried out at Aga khan University Hospital, from January 2010 to December 2010 to determine the etiology and outcome of neonates with pneumothorax in a neonatal tertiary care unit.Results: Ten neonates diagnosed radiologically with pneumothoraces were included. M: F ratio was 1:2.3. Birth weight ranged from 1750-3600 grams with a mean of 2100 grams. The occurrence of pneumothoraces was 50% on the left side, 20% on right, and 30% were bilateral. Primary etiology included pneumonia and sepsis (30%, hyaline membrane disease (20%, meconium aspiration syndrome (20% and congenital diaphragmatic hernia (10%. Spontaneous pneumothoraces were present in 20% of cases. In our study, the incidence of neonatal pneumothoraces was 2.5/1000 births compared to 10-15/1000 in Denmark, 10-20/1000 in Turkey and 6.3/1000 from Vermont Oxford Group. Despite the small number of cases, one incidental finding was the occurrence of pneumothorax, which declined in elective cesarean section after 37 weeks gestation i.e., 1.3 of 1000 births. Mortality was 60% determined mainly by the primary etiology and other co-morbid conditions.Conclusion: The study showed a higher number of mortality cases (60%. Although, it was difficult to draw a conclusion from the limited number of cases, there may be a benefit on neonatal respiratory outcome to be obtained by better selection of mothers and by waiting until 37 weeks before performing elective cesarean section. Adequate clinician training in soft ventilation strategies will reduce the occurrence of pneumothoraces.

    Full Text Available Within the context of climate change, it is of utmost importance to quantify the stability of ecosystems with respect to climate anomalies. It is well acknowledged that ecosystem stability may change over time. As these temporal stability changes may provide a warning for increased vulnerability of the system, this study provides a methodology to quantify and assess these temporal changes in vegetation stability. Within this framework, vegetation stability changes were quantified over Australia from 1982 to 2006 using GIMMS NDVI and climate time series (i.e., SPEI (Standardized Precipitation and Evaporation Index. Starting from a stability assessment on the complete time series, we aim to assess: (i the magnitude and direction of stability changes; and (ii the similarity in these changes for different stability metrics, i.e., the standard deviation of the NDVI anomaly (SD, auto-correlation at lag one of the NDVI anomaly (AC and the correlation of NDVI anomaly with SPEI (CS. Results show high variability in magnitude and direction for the different stability metrics. Large areas and types of Australian vegetation showed an increase in variability (SD over time; however, vegetation memory (AC decreased. The association of NDVI anomalies with drought events (CS showed a mixed response: the association increased in the western part, while it decreased in the eastern part. This methodology shows the potential for quantifying vegetation responses to major climate shifts and land use change, but results could be enhanced with higher resolution time series data.

  5. EMD-RBFNN Coupling Prediction Model of Complex Regional Groundwater Depth Series: A Case Study of the Jiansanjiang Administration of Heilongjiang Land Reclamation in China

    Full Text Available The accurate and reliable prediction of groundwater depth is the basis of the sustainable utilization of regional groundwater resources. However, the complexity of the prediction has been ignored in previous studies of regional groundwater depth system analysis and prediction, making it difficult to realize the scientific management of groundwater resources. To address this defect, taking complexity diagnosis as the research foundation, this paper proposes a new coupling forecast strategy for evaluating groundwater depth based on empirical mode decomposition (EMD and a radial basis function neural network (RBFNN. The data used for complexity analysis and modelling are the monthly groundwater depth series monitoring data from 15 long-term monitoring wells from 1997 to 2007, which were collected from the Jiansanjiang Administration of Heilongjiang Agricultural Reclamation in China. The calculation results of the comprehensive complexity index for each groundwater depth series obtained are based on wavelet theory, fractal theory, and the approximate entropy method. The monthly groundwater depth sequence of District 8 of Farm Nongjiang, which has the highest complexity among the five farms in the Jiansanjiang Administration midland, was chosen as the modelling sample series. The groundwater depth series of District 8 of Farm Nongjiang was separated into five intrinsic mode function (IMF sequences and a remainder sequence by applying the EMD method, which revealed that local groundwater depth has a significant one-year periodic character and an increasing trend. The RBFNN was then used to forecast and stack each EMD separation sequence. The results suggest that the future groundwater depth will remain at approximately 10 m if the past pattern of water use continues, exceeding the ideal depth of groundwater. Thus, local departments should take appropriate countermeasures to conserve groundwater resources effectively.

    Full Text Available Introduction: Time series models are generally categorized as a data-driven method or mathematically-based method. These models are known as one of the most important tools in modeling and forecasting of hydrological processes, which are used to design and scientific management of water resources projects. On the other hand, a better understanding of the river flow process is vital for appropriate streamflow modeling and forecasting. One of the main concerns of hydrological time series modeling is whether the hydrologic variable is governed by the linear or nonlinear models through time. Although the linear time series models have been widely applied in hydrology research, there has been some recent increasing interest in the application of nonlinear time series approaches. The threshold autoregressive (TAR method is frequently applied in modeling the mean (first order moment of financial and economic time series. Thise type of the model has not received considerable attention yet from the hydrological community. The main purposes of this paper are to analyze and to discuss stochastic modeling of daily river flow time series of the study area using linear (such as ARMA: autoregressive integrated moving average and non-linear (such as two- and three- regime TAR models. Material and Methods: The study area has constituted itself of four sub-basins namely, Saghez Chai, Jighato Chai, Khorkhoreh Chai and Sarogh Chai from west to east, respectively, which discharge water into the Zarrineh Roud dam reservoir. River flow time series of 6 hydro-gauge stations located on upstream basin rivers of Zarrineh Roud dam (located in the southern part of Urmia Lake basin were considered to model purposes. All the data series used here to start from January 1, 1997, and ends until December 31, 2011. In this study, the daily river flow data from January 01 1997 to December 31 2009 (13 years were chosen for calibration and data for January 01 2010 to December 31 2011

    Cities have been expanding rapidly worldwide, especially over the past few decades. Mapping the dynamic expansion of impervious surface in both space and time is essential for an improved understanding of the urbanization process, land-cover and land-use change, and their impacts on the environment. Landsat and other medium-resolution satellites provide the necessary spatial details and temporal frequency for mapping impervious surface expansion over the past four decades. Since the US Geological Survey opened the historical record of the Landsat image archive for free access in 2008, the decades-old bottleneck of data limitation has gone. Remote-sensing scientists are now rich with data, and the challenge is how to make best use of this precious resource. In this article, we develop an efficient algorithm to map the continuous expansion of impervious surface using a time series of four decades of medium-resolution satellite images. The algorithm is based on a supervised classification of the time-series image stack using a decision tree. Each imerpervious class represents urbanization starting in a different image. The algorithm also allows us to remove inconsistent training samples because impervious expansion is not reversible during the study period. The objective is to extract a time series of complete and consistent impervious surface maps from a corresponding times series of images collected from multiple sensors, and with a minimal amount of image preprocessing effort. The approach was tested in the lower Yangtze River Delta region, one of the fastest urban growth areas in China. Results from nearly four decades of medium-resolution satellite data from the Landsat Multispectral Scanner (MSS), Thematic Mapper (TM), Enhanced Thematic Mapper plus (ETM+) and China-Brazil Earth Resources Satellite (CBERS) show a consistent urbanization process that is consistent with economic development plans and policies.

    To study the efficacy of subcutaneous steroid injection in the treatment of chalazion. Prospective consecutive case series. University teaching hospital, Hong Kong. Patients with chalazion presenting to the out-patient clinic of the Department of Ophthalmology at the Prince of Wales Hospital from January to June 1998. Size of the chalazion after steroid injection treatment. Forty-eight consecutive patients with chalazion were treated with injection of triamcinolone into the subcutaneous tissue around the lesion. In 43 (89.6%) patients, the lesion subsided completely. Twenty-six (54.2%) patients had lesions that subsided with one injection. The size and duration of the chalazion at presentation did not significantly affect the outcome of the treatment. Two patients developed depigmentation of the skin at the site of injection. No other major complications were encountered. Subcutaneous injection of the steroid triamcinolone acetonide appears to be a simple and effective treatment for chalazion. Further comparative clinical trials are indicated.

    Full Text Available Snus (nass is a form of snuff used in a similar manner to American dipping tobacco, but it does not typically result in a need for spitting. Possible hazards associated with this material include malignant and premalignant lesions in the oral cavity and gastrointestinal tract. The use of smokeless tobacco has increased in the Middle East in recent decades, particularly among teenagers and young adults. Therefore, practitioners must be able to recognize malignant and premalignant lesions. Although, an estimated 10-25% of the world′s population uses smokeless tobacco, this practice is virtually unknown in Iran. The aim of this study is to report a series of cases of squamous cell carcinoma and verrucous carcinoma occurring in the users of snus, who referred to the Department of Oral Medicine in Kerman Dental School.

    Objective. To summarize the characteristics and analysis of relevant factors and to give references for prevention and further study of liver damage associated with Polygonum multiflorum Thunb. (HSW), we provide a systematic review of case reports and case series about liver damage associated with HSW. Methods. An extensive search of 6 medical databases was performed up to June 2014. Case reports and case series involving liver damage associated with HSW were included. Results. This review covers a total of 450 cases in 76 articles. HSW types included raw and processed HSW decoction pieces and many Chinese patent medicines that contain HSW. Symptoms of liver damage occur mostly a month or so after taking the medicine, mainly including jaundice, fatigue, anorexia, and yellow or tawny urine. Of the 450 patients, two cases who received liver transplantation and seven who died, the remaining 441 cases recovered or had liver function improvement after discontinuing HSW products and conservative care. Conclusion. HSW causes liver toxicity and may cause liver damage in different degrees and even lead to death; most of them are much related to long-term and overdose of drugs. Liver damage associated with HSW is reversible, and, after active treatment, the majority can be cured. People should be alert to liver damage when taking HSW preparations. PMID:25648693

    Case series. A salvaged limb is one that has undergone a major traumatic injury, followed by repeated surgical attempts in order to avoid amputation. Psychological recovery for individuals with lower extremity limb salvage has been examined in a number of studies. However, psychosocial reactions for individuals with upper extremity (UE) limb salvage are understudied in the literature. The purpose of this study was to explore the process of psychosocial adaptation for 3 trauma cases after UE limb salvage. The Reactions to Impairment and Disability Inventory was used to assess psychosocial adaptation. Physical function outcomes (pain, range of motion, edema, sensation, and dexterity) are presented. The Disabilities of the Arm, Shoulder, and Hand measure was used to assess perceived disability. Medical and rehabilitation history are discussed for each case, in order to provide in-depth understanding of the impact of these injuries. Reactions to injury varied across the cases; however, outcomes suggest that psychosocial adaptation may be influenced by the experience of pain, the ability to participate in valued roles and activities, and having a supportive social network. For this population, therapists may consider emphasizing pain management, focusing on client-centered goals and interventions, and facilitating peer support. Providers should closely monitor patients for signs of poor adaptation, such as hand-hiding behaviors. This study is among the first to examine psychological outcomes for the UE limb salvage population. Future research would be beneficial to provide deeper understanding of the psychosocial challenges for these individuals. Copyright © 2017 Hanley & Belfus. Published by Elsevier Inc.

    The purpose of this case series was to evaluate both the visual and systemic prognosis of patients with endogenous endophthalmitis. We reported a series of 20 cases of endogenous endophthalmitis occurring between 2012 and 2015 at the university medical center in Toulouse. The mean age was 67 (±43.3) years with a male predominance (n=11). The site of entry was found in 14 cases (87.5%). In 11 cases (69%), the causative agent was a bacterium; a fungal infection was found in five cases. Visual acuity after maximal medical and surgical treatment was limited to "no light perception" in 7 cases (35%), "hand motion" in 2 cases (10%), "finger counting" in 3 cases (15%) and 10/10 in 2 cases (10%). One case had no final data. The main site of entry was found to be associated endocarditis (n=7), central venous line or venipuncture (n=6). The main local complications were retinal detachment (n=6), cataract (n=5) and choroidal neovascularization secondary to scarring (n=2). Endogenous endophthalmitis is associated with poor visual prognosis. It is also often associated with systemic complications that may be life-threatening. Copyright © 2017 Elsevier Masson SAS.

    Tardive syndromes are among the most debilitating side effects associated with use of antipsychotics. In this case series we present 5 cases of drug induced tardive syndromes, who had not responded to many of the other therapeutic measures but responded to clozapine. The response rate with clozapine varied from 50% to 100% and the response was seen by week 3 in most cases. Over the long term follow-up of as long as 6 years the response to clozapine was sustained. In two cases clozapine could be stopped. Copyright © 2014 Elsevier B.V. All rights reserved.

    An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

    A range of single classifiers have been proposed to classify crop types using time series vegetation indices, and hybrid classifiers are used to improve discriminatory power. Traditional fusion rules use the product of multi-single classifiers, but that strategy cannot integrate the classification output of machine learning classifiers. In this research, the performance of two hybrid strategies, multiple voting (M-voting) and probabilistic fusion (P-fusion), for crop classification using NDVI time series were tested with different training sample sizes at both pixel and object levels, and two representative counties in north Xinjiang were selected as study area. The single classifiers employed in this research included Random Forest (RF), Support Vector Machine (SVM), and See 5 (C 5.0). The results indicated that classification performance improved (increased the mean overall accuracy by 5%~10%, and reduced standard deviation of overall accuracy by around 1%) substantially with the training sample number, and when the training sample size was small (50 or 100 training samples), hybrid classifiers substantially outperformed single classifiers with higher mean overall accuracy (1%~2%). However, when abundant training samples (4,000) were employed, single classifiers could achieve good classification accuracy, and all classifiers obtained similar performances. Additionally, although object-based classification did not improve accuracy, it resulted in greater visual appeal, especially in study areas with a heterogeneous cropping pattern.

    Imatinib is a tyrosine kinase inhibitor approved as a first line treatment for chronic myeloid leukemia and gastrointestinal stromal tumors. Usually the drug is well-tolerated with hematological adverse effects being most commonly seen. Dermatological side effects are seen in 9.5-69% of patients on imatinib; majority of which are minor and self-limiting. We, hereby, report a case series of erythroderma occurring secondary to imatinib in two patients with chronic myeloid leukemia. Both the patients improved upon the discontinuation of the drug. The literature review revealed only six probable cases of erythroderma due to imatinib. So, this case series is being reported for the rarity of this adverse effect of imatinib.

    Kawasaki disease is an acute vasculitis of early childhood. Its incidence varies among different ethnic groups with higher rates among Asians. In this case series, we presented four cases of Kawasaki disease with incomplete or atypical presentations in Egyptian children. Two cases presented with meningitis, which is not a criteria for the diagnosis of Kawasaki disease. The other two cases presented with pharyngitis and fever, which did not respond to antibiotics. The clinical criteria for diagnosis of Kawasaki disease were either incomplete or appeared sequentially. Coronary artery aneurysms were detected in one case, while the others had normal coronary by echocardiography. All cases were followed in our clinic, according to international guidelines. Early diagnosis and management of Kawasaki disease are important to ensure a good outcome and a high index of suspicion in febrile children is required irrespective of the clinical presentation.

    Case reports and case series or case study research are descriptive studies that are prepared for illustrating novel, unusual, or atypical features identified in patients in medical practice, and they potentially generate new research questions. They are empirical inquiries or investigations of a patient or a group of patients in a natural, real-world clinical setting. Case study research is a method that focuses on the contextual analysis of a number of events or conditions and their relationships. There is disagreement among physicians on the value of case studies in the medical literature, particularly for educators focused on teaching evidence-based medicine (EBM) for student learners in graduate medical education. Despite their limitations, case study research is a beneficial tool and learning experience in graduate medical education and among novice researchers. The preparation and presentation of case studies can help students and graduate medical education programs evaluate and apply the six American College of Graduate Medical Education (ACGME) competencies in the areas of medical knowledge, patient care, practice-based learning, professionalism, systems-based practice, and communication. A goal in graduate medical education should be to assist residents to expand their critical thinking, problem-solving, and decision-making skills. These attributes are required in the teaching and practice of EBM. In this aspect, case studies provide a platform for developing clinical skills and problem-based learning methods. Hence, graduate medical education programs should encourage, assist, and support residents in the publication of clinical case studies; and clinical teachers should encourage graduate students to publish case reports during their graduate medical education.

    2016-12-01

    Full Text Available We all know the enigma that compels us to dive into the excitement and vivacity of a certain story we are reading or a series we are watching. The characters become a part of us and the streets, café shops, etc., design our thoughts and dreams as they display the ‘vitrines’ of our reality. All is triggered by a simple word “once upon a time.” In this article, we go in-depth by analyzing storytelling and by exploring the significant role of the character as positioned in a text. However, our main concern is the possibility of being able to decipher values transmitted by a text, where the character plays a major role in terms of reflecting empathy/sympathy towards audiences’ perceptions. We, therefore, came with the idea of designing an innovative value analysis framework – based on Pierre Glaudes’s and Yves Reuter’s grid analysis pattern for value depiction – where two studies that analyze the famous series Bab El Hara, are cross referenced. Then, in order to test the validity of the framework, an original qualitative analysis based on a focus group session is conducted on ten Lebanese respondents (aged between 35 and 45 who relate their personal opinions and beliefs in terms of what they perceive in Bab El Hara, giving, therefore, indication to what values they identify with the most. Effectively, the values which respondents did identify with seemed to correspond perfectly with the value analysis framework which has shown to be a suitable base for value depiction.

    Treating corneal neurotrophic ulcers is challenging. Topical application of matrix regeneration therapy (RGTA), which is a dextran derivative polymer and heparan sulfate analog, is a promising regenerative therapy and an alternative or additional therapeutic regimen when corneal healing is compromised. The aim of this study was to evaluate the efficacy of RGTA (Cacicol) in the treatment of 6 patients with severe neurotrophic ulcers. We present an uncontrolled prospective case series of 6 patients (6 eyes) with severe corneal neurotrophic ulcers. Patients were treated with topical RGTA at a dose of 1 drop every second day. The main outcome measure was complete corneal epithelialization. We measured corneal thickness by anterior segment swept-source optical coherence tomography. Two patients (33%) showed complete corneal healing, one at 6 weeks and the other at 10 weeks. Treatment was considered failure in 4 patients (67%), and 1 patient had corneal perforation. None of the patients showed improvement in best-corrected visual acuity. There were no RGTA-related local or systemic side effects. Based on previous studies, RGTA seems to be a promising therapeutic agent for controlling ocular surface inflammation and promoting corneal healing. In this study, the efficacy of RGTA did not match the encouraging results from previous reports.

    The recently introduced new nosological category, Gastro Intestinal Stromal Tumors, brought the Authors to a revision of their series and to a critical analysis of surgical behaviour for the treatment of that pathology. A series of 23 cases of GIST, observed between 1977 and 1999 has been taken into account. In the earlier cases, histopathological classification has been reviewed according to the most used criterions in international scientific literature. 17 of 23 observed tumors were located on the stomach, 4 on the duodenum and 2 on the jejunum. 20 of these cases derived from muscular tissue and 3 cases derived both from muscular and neural tissues. In 7 cases (30%) tumors were accidentally discovered during surgical intervention or diagnostic procedures for other causes. Surgical treatment was performed in all cases and consisted in 6 gastric resections, 14 gastric free-margin excisions, 2 duodenal resections and 1 jejunal resection. The follow-up (performed on 18 patients, with a minimum of 1 year, a maximum of 17 years and a median of 6 years) showed 2 deaths (11%) due to oncological causes, while 2 of the patients (11%) died for other causes. The only treatment for that group of tumors is, at the moment, surgery. Although that kind of neoplasms has mainly non-aggressive biological behaviour, a radical resection must be performed, due to the absence of macroscopic criterions to help distinguishing, during surgical intervention, aggressive tumors from non-aggressive ones.

  8. Vehicle speed prediction via a sliding-window time series analysis and an evolutionary least learning machine: A case study on San Francisco urban roads

    2015-06-01

    Full Text Available The main goal of the current study is to take advantage of advanced numerical and intelligent tools to predict the speed of a vehicle using time series. It is clear that the uncertainty caused by temporal behavior of the driver as well as various external disturbances on the road will affect the vehicle speed, and thus, the vehicle power demands. The prediction of upcoming power demands can be employed by the vehicle powertrain control systems to improve significantly the fuel economy and emission performance. Therefore, it is important to systems design engineers and automotive industrialists to develop efficient numerical tools to overcome the risk of unpredictability associated with the vehicle speed profile on roads. In this study, the authors propose an intelligent tool called evolutionary least learning machine (E-LLM to forecast the vehicle speed sequence. To have a practical evaluation regarding the efficacy of E-LLM, the authors use the driving data collected on the San Francisco urban roads by a private Honda Insight vehicle. The concept of sliding window time series (SWTS analysis is used to prepare the database for the speed forecasting process. To evaluate the performance of the proposed technique, a number of well-known approaches, such as auto regressive (AR method, back-propagation neural network (BPNN, evolutionary extreme learning machine (E-ELM, extreme learning machine (ELM, and radial basis function neural network (RBFNN, are considered. The performances of the rival methods are then compared in terms of the mean square error (MSE, root mean square error (RMSE, mean absolute percentage error (MAPE, median absolute percentage error (MDAPE, and absolute fraction of variances (R2 metrics. Through an exhaustive comparative study, the authors observed that E-LLM is a powerful tool for predicting the vehicle speed profiles. The outcomes of the current study can be of use for the engineers of automotive industry who have been

  9. A case series of Osteoid Osteoma: 7 cases

    Directory of Open Access Journals (Sweden)

    Farzan M

    1997-08-01

    Full Text Available Osteoid osteoma is a unique benign primary bone tumor that may present in the metaphyseal diaphyseal areas of the short tubular bones and has also been reported in the carpal bones. It occurs in the first two decades of life. The classic history is bone pain, often relieved by aspirin. The clinical appearance is local swelling and tenderness. The typical radiographic appearance is very characteristic: an eccentric area of cortical sclerosis, frequently with a radiolucent nidus. The lesion does not exceed 1 cm in diameter. The use of a bone scan may be helpful diagnostically, as are the CAT scan and tomography. Doyle et al described seven cases of osteoid osteoma with a prolonged delay in diagnosis, but reported an excellent cure rate following excision. The carpus is not unusual as a site for this tumor, especially the scaphoid. Treatment is windowing with curettage of the tumor nidus. The use of a dental drill to window the phalanx and expose the nidus is very helpful. Removal of the entire nidus is permanently curative, but if a portion of the tumor is missed, prompt recurrence of the symptoms is the rule.

    Treatment of equine metabolic syndrome (EMS) is essential to improve insulin sensitivity and reduce the risk of laminitis. Calorie restriction and increased exercise are the mainstays of treatment but there is potential for poor owner compliance. To determine whether significant weight loss accompanied by improvements in measures of insulin sensitivity can be achieved in horses and ponies with EMS managed by their owners in their normal environment under veterinary guidance. Retrospective clinical case series. Horses and ponies attending 2 university hospitals for investigation and treatment of suspected EMS were eligible for inclusion in the study. Animals underwent a clinical examination, basal and dynamic endocrine testing; those with pituitary pars intermedia dysfunction (PPID) were excluded. Owners were given individually tailored diet and exercise programmes to follow for between 3 and 6 months. After the treatment period, clinical examination and endocrine tests were repeated and results compared to the initial assessment. Nineteen animals were recruited to the study, 17 with a history of laminitis. All animals showed a reduction in body condition score (Passessments. There were significant (P<0.05) reductions in basal insulin, insulin at 45 min during a combined glucose insulin tolerance test (CGIT), time for blood glucose concentration to return to baseline during a CGIT and mean area under the glucose curve. A diet and exercise programme tailored to the needs of the individual animal and implemented by the owner results in weight loss accompanied by improvements in insulin sensitivity. © 2015 EVJ Ltd.

    The objective of the study is to present a large case series of parapharyngeal space tumors (PPST) and the most comprehensive literature review of tumor histopathologic distribution. The study was designed as internal case series and full Pubmed/MEDLINE electronic database review in a tertiary academic medical center. Tumor histopathology and patient demographics were obtained from a comprehensive Pubmed/MEDLINE database review, as well from an internal case series of 117 patients referred to our center between 1993 and 2013. Main outcome and measures of the study were to define the age, gender, and histopathology of PPST within a large internal case series and among the current body of published literature, and to propose a diagnostic and treatment algorithm for these tumors. Our cohort included 117 cases, 58 females and 59 males, with benign tumors comprising 85 % (n = 99) and malignant tumors 15 % (n = 18). A systematic review of published literature from 1963 to the present revealed 37 case series, and when combined with our present series, yielded a total of 2160 cases. Benign tumors are most common (78.8 %), with tumors of salivary gland (44.4 %), neural (34.4 %), and vascular (2.64 %) origin representing the largest subtypes. Pleomorphic adenomas (30.9 %), paragangliomas (13.1 %), and schwannomas (12.3 %) comprised the majority of all cases. Due to their rarity, data regarding the histopathologic distribution of PPST is scarce. We provide one of the largest case series and the most comprehensive review of these tumors in the literature to date, and offer our algorithm for evaluation and treatment.

    Full Text Available Dens invaginatus is a developmental anomaly resulting from an invagination in the surface of a tooth crown before its calcification. It involves more commonly maxillary anterior teeth. Dens invaginatus with supernumerary teeth and double dens invagintus were also reported. The management of dens invaginatus includes simple prophylactic restoration to conventional endodontic treatment or extraction, depending on the type of invagination, function, esthetics, and morphology of the root canal. Extraction is indicated as a last choice of treatment in cases of failure of root canal treatment and in supernumerary teeth associated with dens invaginatus. In this paper, we have reported a series of cases of dens invagintus.

    Full Text Available Traditional Chinese medicine (TCM has been widely used in cancer in China. Case series report a series of cases exposed to a certain intervention. To understand the current situation of case series of TCM for cancer, we performed this review. We included case series of cancer patients treated with TCM therapy. Electronic searches were conducted in four main Chinese databases until February 2011. A total of 1,217 reports of case series (92,945 patients were included. The top five types of cancer were lung cancer, liver cancer, stomach cancer, leukemia, and esophageal cancer. Leukopenia and hiccup treated by TCM were the most common adverse reactions after surgery or induced by chemo/radiotherapy. More than half of the patients were treated with TCM therapies alone. The application of herbal medicines especially formula based on syndrome differentiation was highly prevalent, and the typical administration route was oral usage. 1,182 reports were published in a structured format. The quantity of TCM case series for cancer treatment is substantial. Further studies should focus on the most common types of cancer and the most frequently applied TCM therapies. We presented a recommendation from the methodological point of view for the format of reporting.

    To investigate the radiographic findings of mucopolysaccharidoses (MPS) on panoramic radiographs in a series of 16 patients. This retrospective cross-sectional study included panoramic radiographs of 16 patients with cytogenetically diagnosed MPS. Two blinded, previously calibrated observers evaluate the presence or absence of the following features: type of dentition; stage of dental age in comparison with chronologic age; delayed exfoliation of deciduous teeth; supernumerary teeth; teeth impaction; enlarged, cyst-like dental crypt; hypercementosis; taurodontism; generalized enamel hypoplasia; enlargement of the bone marrow spaces; thinning of cortical bone; unusual morphology of condyles; and flattening of the condylar head. The final sample was composed of 8 MPS IV, 7 MPS VI, and 1 MPS I cases. All patients presented unusual morphology of condyles. Cyst-like dental crypt (75%), taurodontism, and teeth impaction (68.75% each) were also overall common findings. Generalized enamel hypoplasia was exclusively identified in patients with MPS IV (75% of those patients). Radiographic features of oral and maxillofacial manifestations in patients with MPS frequently encountered by dentists may help recognize the disorder. However, because of sample size limitations, it was not possible to infer any statistical relationship between the radiographic features and the types of MPS. Copyright © 2015 Elsevier Inc.

    Although liver biopsy is an easy procedure for hospitalized patients and outpatients, some complications may occur. To evaluate the efficiency, complications, safety and clinicopathological utility of ultrasonographic-guided percutaneous liver biopsy in diffuse liver disease. In our retrospective study, we evaluated ultrasound-assisted needle biopsies that were performed in outpatients from October 2006 to July 2010. The liver biopsies were performed following one-night fasting using the tru-cut biopsy gun (18-20 gauge) after marking the best seen and hypovascular part of the liver, distant enough from the adjacent organs. A total of 1018 patients were referred to our radiology department. Most of the patients had hepatitis B (60.6%). The biopsy specimens were recorded and sent to our pathology department for histopathological examination. According to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. We resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. The complication rate is very low. The US-assisted percutaneous liver biopsy should be used for all cases

    To describe our experience in the management of patients with osteogenesis imperfect (OI). We conducted a retrospective study of a series of cases affected with OI treated in the Clínica Univesidad de Navarra from 1980 to 2007, with a mean follow up of 17.3 years (7-27 years). We collected descriptive data of the sample, the fractures and the deformities, and the treatments given. The complications presented and the functional outcomes at the end of follow-up were also reviewed. The sample included ten patients. Approximately two-thirds (65%) of fractures were sustained in the lower limbs. One patient received medical treatment only. Three patients had combined medical and surgical treatment. Some type of surgical treatment was performed on 6 patients. The most common surgery was the Sofield-Millar performed on 37 occasions, with a third of them requiring revision surgery due to migration of the nails. There were 17 episodes of re-fracture. Complications such as non-union, iatrogenic fractures, and infections, were also observed. The functional outcome, according to the Hoffer-Bullock scale, at the end of follow-up was grade I/II in 7 patients. Despite the need for multiple interventions and complications presented during follow up, the appropriate treatment of patients with OI can provide acceptable functional outcomes.

    2018-01-01

    To describe a modified rib pivot thoracotomy and its clinical application in client-owned dogs and cats. Case series of 24 dogs and 1 cat requiring a thoracotomy. A lateral thoracic incision over the required thoracic segment was made. The latissimus dorsi muscle was reflected dorsally. The predetermined rib was identified and the periosteum overlying the rib was elevated circumferentially, avoiding the intercostal neurovascular structures. Holes were pre-placed above and below the proposed osteotomy site. The rib was osteotomised and pivoted cranially. The pleura was incised and the required intrathoracic procedure was then performed. The thoracic cavity was closed by pre-placement of a suture through the pre-placed holes within the osteotomised rib. The pleura and intercostal musculature were closed, avoiding the intercostal neurovascular structures. The rib was re-apposed and the lateral approach was closed. The cases included were reviewed for both the rib pivoted as per the procedure required and postoperative complications. The study group comprised 8 Staffordshire Bull Terriers, 2 Poodles, 2 German Shepherd Dogs, 1 each of Basset Hound, Rhodesian Ridgeback, Golden Retriever, Australian Shepherd, Vizsla, Bull Mastiff, Schnauzer, Jack Russell Terrier, Bulldog, Deerhound, Labrador Retriever and Australian Terrier, and 1 cat. A modified rib pivot thoracotomy was performed for lung lobectomy (n = 11), oesophagectomy (7), subtotal pericardectomy (5), patent ductus arteriosus ligation (1) and thoracic duct ligation (1). Follow-up ranged from 2 to 40 weeks postoperatively. Postoperative complications included seroma formation in two dogs. A modified rib pivot thoracotomy should be considered as an alternative lateral thoracic approach with good exposure, minimal complications and low morbidity. © 2018 Australian Veterinary Association.

    Full Text Available Objective: To study a case series of genital malignancies coexisting with genital tuberculosis. Materials and Methods: A series of three cases with known genital malignancies were found to have coexisting genital tuberculosis on subsequent workup. Results: First case was a 45 years old lady who underwent staging laparotomy for ovarian cancer. On histopathology examination, there was coexisting tuberculosis with papillary serous carcinoma. Second case was 53 years old postmenopausal lady who underwent extrafascial hysterectomy along with pelvic lymph node dissection. Histopathology showed tubercular changes along with endometrial malignancy. Third patient was a 50 years old postmenopausal lady with stage IIA carcinoma of cervix. She underwent radical hysterectomy and histopathology revealed tubercular changes in pelvic lymph nodes. All patients were given antitubercular therapy for 9 months in postoperative period along with adjuvant therapy. Conclusion: Although diagnosed as an incidental finding in the case series, genital tuberculosis may present in patients with malignancies as a result of immunosupression.

    Brucellosis is a zoonosis caused by Brucella spp. It may be acquired by consuming unpasteurized dairy products. Brucellosis has a low incidence in Chile, thus, we have a scarce data. To report and to characterize the first series of clinical cases of adult patients diagnosed with brucellosis in Chile. We describe a series of 13 clinical cases in patients diagnosed between 2000 and 2016 in three different centers in the Metropolitan Region, Chile. A retrospective analysis was performed on clinical presentation, laboratory, antibiotic treatment, morbidity and mortality. The mean age was 50 years old. Eight cases had a record of consumption of unpasteurized dairy products. The most frequently reported complaints were fever. The most frequent focal point involved was the spine. Only one patient had a positive blood culture, while the diagnosis was made using serological techniques in the other part of the group. The most indicated antibiotic regimens were doxycycline-rifampicin and doxycycline-gentamicin. The hospital stay was 20 days approximately as an average. Clinical cure was achieved in all cases. Brucellosis is an infrequent zoonosis in Chile, and it produces a nonspecific clinical picture, so it is necessary to have high suspicion to make the diagnosis based in the antecedent of consumption of unpasteurized dairy or raw meat.

    2016-11-01

    Full Text Available Although the past few decades have witnessed the great development of Synthetic Aperture Radar Interferometry (InSAR technology in the monitoring of landslides, such applications are limited by geometric distortions and ambiguity of 1D Line-Of-Sight (LOS measurements, both of which are the fundamental weakness of InSAR. Integration of multi-sensor InSAR datasets has recently shown its great potential in breaking through the two limits. In this study, 16 ascending images from the Advanced Land Observing Satellite (ALOS and 18 descending images from the Environmental Satellite (ENVISAT have been integrated to characterize and to detect the slow-moving landslides in Zhouqu, China between 2008 and 2010. Geometric distortions are first mapped by using the imaging geometric parameters of the used SAR data and public Digital Elevation Model (DEM data of Zhouqu, which allow the determination of the most appropriate data assembly for a particular slope. Subsequently, deformation rates along respective LOS directions of ALOS ascending and ENVISAT descending tracks are estimated by conducting InSAR time series analysis with a Temporarily Coherent Point (TCP-InSAR algorithm. As indicated by the geometric distortion results, 3D deformation rates of the Xieliupo slope at the east bank of the Pai-lung River are finally reconstructed by joint exploiting of the LOS deformation rates from cross-heading datasets based on the surface–parallel flow assumption. It is revealed that the synergistic results of ALOS and ENVISAT datasets provide a more comprehensive understanding and monitoring of the slow-moving landslides in Zhouqu.

    The synergy between Mycobacterium tuberculosis infection and human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome is well established but not so in Buruli ulcer (BU). We screened confirmed BU cases for HIV infection and followed seven BU/HIV-coinfected patients. Management of BU/HIV was based on the World Health Organization guidelines and patient condition. The HIV positivity among BU patients (8.2%; 11/134) was higher compared with that of general patients attending the facility (4.8%; 718/14,863; P = 0.07) and that of pregnant women alone (2.5%; 279/11,125; P = 0.001). All seven BU/HIV-coinfected cases enrolled in the study presented with very large (category III) lesions with four having multiple lesions compared with 54.5% of category III lesions among HIV-negative BU patients. During the recommended BU treatment with streptomycin and rifampicin (SR) all patients developed immune infiltrates including CD4 T cells in their lesions. However, one patient who received antiretroviral therapy (ART) 1 week after beginning SR treatment developed four additional lesions during antibiotic treatment, while two out of the four who did not receive ART died. Further evidence is required to ascertain the most appropriate time to commence ART in relation to SR treatment to minimize paradoxical reactions. © The American Society of Tropical Medicine and Hygiene.

    Clinical symptoms, biochemical analyses, immunologic status and angiographic findings corresponding to seven HBsAg positive patients with panarteritis nodosa and to 16 HBsAg negative patients with panarteritis nodosa have been compared. HBsAg positive cases showed a statistical significant higher incidences of Raynaud's phenomenon (p less than 0.05) and cardiopathies (p les than 0.05), as well as high occurrence of blood hypertension, artropathy, liver involvement and peripheral neuropathy. Significant differences in relation to cell immunity were not found. Humoral immune disturbances were more common among HBsAg positive patients, being hypergammaglobulinemia (p less than 0.01), IgM increase and decrease of complement factors (C3, C4 and C3PA) the most frequent abnormalities recorded. Angiographic studies revealed a high incidence of microaneurisms for the HBsAg positive group.

    Systemic Lupus Erythematosus (SLE) and Tuberculosis (TB) are intricately related with an increase in the risk of TB in SLE. Primary mechanisms pertaining to the increased susceptibility for TB are the inherent immunodeficient state of SLE and use of immunosuppressant agents in the treatment of SLE. We report a case series of five female patients of SLE with TB who presented between January 2015 and December 2015 in a tertiary care teaching hospital in North Eastern India. All the patients were young to middle aged females having SLE with or without lupus nephritis who were on immunosuppressive therapy with corticosteroids, mycophenolate mofetil or cyclophosphamide. Two of the cases had sputum positive pulmonary tuberculosis while rest had Extra-Pulmonary TB (EPTB). The response to anti-tubercular therapy led to clinical improvement in all the cases except one who had an adverse outcome. Our series further substantiates the increased risk of TB in SLE thus, prompting further research towards better management of these two disease entities in conjunction.

  12. Patterns of retroperitoneal trauma following gunshot violence: A case series

    Full Text Available Introduction: Abdominal trauma is defined as any injury to the abdomen and its containing viscera. Common penetrating injuries including gunshot or stab injuries are increasing worldwide. However, retroperitoneal gunshot injuries have a lower incidence than trans-abdominal trauma and can have substantially different outcomes. Case report: We report a series of three family members involved in gunshot violence over an18-month period. Each sustained retroperitoneal gunshot injuries with varying injuries patterns and treatment courses. Interestingly, one patient had a delayed small bowel perforation on day 6 post injury. Discussion: Retroperitoneal trauma following gun violence has a lower incidence than trans-abdominal trauma. There is a paucity of literature describing injury patterns following this type of injury and their subsequent management. In the context of penetrating retroperitoneal trauma, the retroperitoneal organs are at risk and therefore serial clinical and/or radiological assessment is necessary. Delayed small bowel injury as a consequence of retroperitoneal gunshot is an unusual finding, with no reports to our knowledge in the literature. Conclusion: this case series highlight that penetrating retroperitoneal trauma can produce a variety of injury patterns. Therefore a wide clinical acumen is needed to ensure a successful outcome. The trajectory of the bullet may help ascertain potential injuries, but serial assessment and observation are also important. Ultimately, individual cases must be treated accordingly, based on clinical stability, severity of injury and radiological findings. Despite initial stability, patients should always be observed for delayed complications. Keywords: Retroperitoneal, trauma, gunshot, management

    A nontraditional form of exercise recently applied for patients with Parkinson disease (PD) is boxing training. The primary purpose of this case series is to describe the effects of disease severity and duration of boxing training (short term and long term) on changes in balance, mobility, and quality of life for patients with mild or moderate to severe PD. The feasibility and safety of the boxing training program also were assessed. Six patients with idiopathic PD attended 24 to 36 boxing training sessions for 12 weeks, with the option of continuing the training for an additional 24 weeks (a seventh patient attended sessions for only 4 weeks). The 90-minute sessions included boxing drills and traditional stretching, strengthening, and endurance exercises. Outcomes were tested at the baseline and after 12, 24, and 36 weeks of boxing sessions (12-, 24-, and 36-week tests). The outcome measures were the Functional Reach Test, Berg Balance Scale, Activities-specific Balance Confidence Scale, Timed "Up & Go" Test, Six-Minute Walk Test, gait speed, cadence, stride length, step width, activities of daily living and motor examination subscales of the Unified Parkinson Disease Rating Scale, and Parkinson Disease Quality of Life Scale. Six patients completed all phases of the case series, showed improvements on at least 5 of the 12 outcome measures over the baseline at the 12-week test, and showed continued improvements at the 24- and 36-week tests. Patients with mild PD typically showed improvements earlier than those with moderate to severe PD. Despite the progressive nature of PD, the patients in this case series showed short-term and long-term improvements in balance, gait, activities of daily living, and quality of life after the boxing training program. A longer duration of training was necessary for patients with moderate to severe PD to show maximal training outcomes. The boxing training program was feasible and safe for these patients with PD.

    Full Text Available Synthetic cannabinoid use has risen at alarming rates. This case series describes 11 patients exposed to the synthetic cannabinoid, MAB-CHMINACA who presented to an emergency department with life-threatening toxicity including obtundation, severe agitation, seizures and death. All patients required sedatives for agitation, nine required endotracheal intubation, three experienced seizures, and one developed hyperthermia. One developed anoxic brain injury, rhabdomyolysis and died. A significant number were pediatric patients. The mainstay of treatment was aggressive sedation and respiratory support. Synthetic cannabinoids pose a major public health risk. Emergency physicians must be aware of their clinical presentation, diagnosis and treatment.

    2017-10-01

    Full Text Available The incidence of cephalosporin induced hypersensitivity reactions in non-penicillin allergic patients is about 1.7% and in penicillin allergic patients it is about 3-5%. Infact, cephalosporins are considered as the first choice in penicillin allergic patients who need antibiotic therapy intraoperatively. Prompt identification of patients with beta-lactam allergy would lead to an improved utilization of antibiotics and reduced occurrence of resistant strains. We hereby attempt to present a series of cases where ceftriaxone has been implicated in the manifestation of various hypersensitivity reactions. We have also tried to highlight some of the errors, risk factors and other drugs that precipitate a hypersensitivity reaction.

    Transsellar transsphenoidal encephalocele is the least common type of basal encephalocele. We present a series of four cases of transsellar transsphenoidal encephalocele. Clinical findings, imaging reviews, surgical repair techniques and postoperative morbidity are discussed with the relevant literature. Non contrast CT scan head with 3D reconstruction and magnetic resonance imaging should be done in all patients of transsphenoidal encephalocele. Endocrine assessment is also essential. Repair of a transsphenoidal encephalocele should be coordinated between a team of neurosurgeons and ENT surgeon. Our surgical outcome supports the transpalatal/ transnasal approach over the transcranial approach.

    Full Text Available Congenital esophageal stenosis (CES is rare condition found in 1 per 25,000 to 50,000 live births. It is characterized by intrinsic narrowing of the esophagus secondary to congenital malformation of the esophageal wall architecture. Diagnosis is often difficult to definitively establish as the symptoms are often initially attributed to esophageal strictures secondary to reflux, or occur within the context of a tracheo-esophageal fistula (TEF in the newborn. Endoscopic dilation and surgical repair are the mainstays of treatment. We report a series of three cases seen recently at our institution, the University of Alberta/Stollery Children's Hospital.

    Revegetation of abandoned aquaculture regions should be a priority for any integrated coastal zone management (ICZM). This paper examines the potential of a matchless time series of 20 very high spatial resolution (VHSR) optical satellite images acquired for mapping trends in the evolution of mangrove forests from 2001 to 2015 in an estuary fragmented into aquaculture ponds. Evolution of mangrove extent was quantified through robust multitemporal analysis based on supervised image classification. Results indicated that mangroves are expanding inside and outside ponds and over pond dykes. However, the yearly expansion rate of vegetation cover greatly varied between replanted ponds. Ground truthing showed that only Rhizophora species had been planted, whereas natural mangroves consist of Avicennia and Sonneratia species. In addition, the dense Rhizophora plantations present very low regeneration capabilities compared with natural mangroves. Time series of VHSR images provide comprehensive and intuitive level of information for the support of ICZM. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The objective of this study was to investigate the feasibility of game-based robotic training of the ankle in children with cerebral palsy (CP). The design was a case study, 12 weeks intervention, with no follow-up. The setting was a university research laboratory. The participants were a referred sample of three children with cerebral palsy, age 7-12, all male. All completed the intervention. Participants trained on the Rutgers Ankle CP system for 36 rehabilitation sessions (12 weeks, three times/week), playing two custom virtual reality games. The games were played while participants were seated, and trained one ankle at-a-time for strength, motor control, and coordination. The primary study outcome measures were for impairment (DF/PF torques, DF initial contact angle and gait speed), function (GMFM), and quality of life (Peds QL). Secondary outcome measures relate to game performance (game scores as reflective of ankle motor control and endurance). Gait function improved substantially in ankle kinematics, speed and endurance. Overall function (GMFM) indicated improvements that were typical of other ankle strength training programs. Quality of life increased beyond what would be considered a minimal clinical important difference. Game performance improved in both games during the intervention. This feasibility study supports the assumption that game-based robotic training of the ankle benefits gait in children with CP. Game technology is appropriate for the age group and was well accepted by the participants. Additional studies are needed however, to quantify the level of benefit and compare the approach presented here to traditional methods of therapy.

  1. Statistical and Fractal Approaches on Long Time-Series to Surface-Water/Groundwater Relationship Assessment: A Central Italy Alluvial Plain Case Study

    Alessandro Chiaudani

    2017-11-01

    Full Text Available In this research, univariate and bivariate statistical methods were applied to rainfall, river and piezometric level datasets belonging to 24-year time series (1986–2009. These methods, which often are used to understand the effects of precipitation on rivers and karstic springs discharge, have been used to assess piezometric level response to rainfall and river level fluctuations in a porous aquifer. A rain gauge, a river level gauge and three wells, located in Central Italy along the lower Pescara River valley in correspondence of its important alluvial aquifer, provided the data. Statistical analysis has been used within a known hydrogeological framework, which has been refined by mean of a photo-interpretation and a GPS survey. Water–groundwater relationships were identified following the autocorrelation and cross-correlation analyses. Spectral analysis and mono-fractal features of time series were assessed to provide information on multi-year variability, data distributions, their fractal dimension and the distribution return time within the historical time series. The statistical–mathematical results were interpreted through fieldwork that identified distinct groundwater flowpaths within the aquifer and enabled the implementation of a conceptual model, improving the knowledge on water resources management tools.

    This retrospective study evaluates the results of wireless tension band wire (WTBW) which is a modified technique of tension band wires (TBW) for Mayo type II A and III A olecranon fractures. In this technique the K-wires of the TBW are replaced by a cerclage wire while keeping the figure of eight wiring. We reviewed retrospectively our WTBW cases done between 2000 and 2015 where we replaced the K-wires by a cerclage wire. In this technique no hardware migration is possible. Patients were evaluated clinically, radiographicaly and a DASH score was measured. Seventeen patients were reviewed with a mean age of 58.5 years. The mean follow-up period was 58.5 months. The mean DASH score was 12 with 7 patients having a DASH score of zero. Joint mobility was near normal compared to the other side with loss of a mean of 4º in elbow extension and a mean of 3º in elbow flexion. In comparison with other series, in addition to good results, hardware removal for medical reasons was the lowest in our technique. It was needed in three patients for pain on elbow contact and in one with ulnar nerve irritation. This represents a rate of 23.5%. Undesirable events related to the use of K-wires in standard tension band wiring, such as wire migration, wire protrusion through the skin and wire impingement, are absent in the wireless tension band wiring. The high rate of patient satisfaction, good clinical results as well as low rate of needed hardware removal make this technique preferable for fixing Mayo Type II A olecranon fractures.

    To investigate outcomes after surgical repair of distal biceps tendon rupture and the influence of arm dominance on isokinetic flexion and supination results. While relatively uncommon, rupture of the distal biceps tendon can result in significant strength deficits, for which surgical repair is recommended. The purpose of this study was to assess patient reported functional outcomes and muscle performance following surgery. A sample of 23 participants (22 males, 1 female), who had previously undergone surgical repair of the distal biceps tendon, were re-examined at a minimum of one year after surgery. Biodex isokinetic elbow flexion and supination testing was performed to assess strength (as measured by peak torque) and endurance (as measured by total work and work fatigue). The Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Mayo Elbow Performance Scale (MEPS) were used to assess participants' subjectively reported functional recovery. At a mean of 7.6 years after surgical repair, there were no differences between the repaired and uninvolved elbows in peak torque ( p  = 0.47) or total work ( p  = 0.60) for flexion or supination. There was also no difference in elbow flexion work fatigue ( p  = 0.22). However, there was significantly less work fatigue in supination, which was likely influenced by arm dominance, as most repairs were to the dominant arm, F (1,22)=5.67, p  = 0.03. The long-term strength of the repaired elbow was similar to the uninvolved elbow after surgery to the distal biceps tendon. Endurance of the repaired elbow was similar in flexion but greater in supination, probably influenced by arm dominance. Retrospective case series. Level 4.

    Full Text Available Papilledema has long been considered a hallmark of idiopathic intracranial hypertension, a disease defined by elevated intracranial pressure with indiscernible etiology. Papilledema is often seen in the pediatric population, and as such can lead to delays in diagnosis, and often misdiagnosis. Here, we describe three children who were confirmed to have idiopathic intracranial hypertension with raised intracranial pressure by repeated lumbar puncture or intracranial pressure monitoring, normal neuroimaging and absence of papilledema. All three cases had atypical clinical presentations with visual disturbances or photophobia. The patients had a normal body mass index. This case series demonstrates that idiopathic intracranial hypertension can manifest in the absence of clinically obvious papilledema, and has, as such, the potential to cause permanent visual loss if the diagnosis is missed.

    Chediak-Higashi syndrome (CHS) is a rare autosomal recessive disease, characterized by partial oculocutaneous albinism, frequent pyogenic infections, and the presence of abnormal large granules in leukocytes and other granulecontaining cells. The abnormal granules are readily seen in blood and marrow granulocytes. Other clinical features include silvery hair, photophobia, nystagmus and hepatosplenomegaly. However, the presence of abnormal giant intracytoplasmic granules in neutrophils and their precursors are diagnostic of CHS. Here, we present a series of five cases, out of which four presented in the accelerated phase. In all the five cases, the giant granules were noted predominantly in the cytoplasm of lymphocytes, which is a rare occurrence compared to those present in the granulocytes.

    A novel Y-shaped baffle has been proposed for the Fontan operation with promising initial results. However, previous studies have relied either on idealized models or a single patient-specific model. The objective of this study is to comprehensively compare the hemodynamic performance and hepatic blood flow distribution of the Y-graft Fontan baffle with 2 current designs using multiple patient-specific models. Y-shaped and tube-shaped grafts were virtually implanted into 5 patient-specific Glenn models forming 3 types of Fontan geometries: Y-graft, T-junction, and offset. Unsteady flow simulations were performed at rest and at varying exercise conditions. The hepatic flow distribution between the right and left lungs was carefully quantified using a particle tracking method. Other physiologically relevant parameters such as energy dissipation, superior vena cava pressure, and wall shear stress were evaluated. The Fontan geometry significantly influences the hepatic flow distribution. The Y-graft design improves the hepatic flow distribution effectively in 4 of 5 patients, whereas the T-junction and offset designs may skew as much as 97% of hepatic flow to 1 lung in 2 cases. Sensitivity studies show that changes in pulmonary flow split can affect the hepatic flow distribution dramatically but that some Y-graft and T-junction designs are relatively less sensitive than offset designs. The Y-graft design offers moderate improvements over the traditional designs in power loss and superior vena cava pressure in all patients. The Y-graft Fontan design achieves overall superior hemodynamic performance compared with traditional designs. However, the results emphasize that no one-size-fits-all solution is available that will universally benefit all patients and that designs should be customized for individual patients before clinical application.

    Background Since the ophthalmological community adopted the use of intravitreal bevacizumab as an accepted off-label treatment for neovascular diseases, the amount of knowledge regarding its effects and properties has been increasing continually. In the last few years, there have been an increasing number of reports about sterile intraocular inflammation and intraocular pressure elevations after intravitreal bevacizumab. In the following case series, we describe the clinical presentation and outcomes of ten consecutive cases of patients developing mild-to-severe sterile intraocular inflammation after intravitreal bevacizumab and their management. Methods This report presents a retrospective case series. We reviewed the medical records of ten consecutive patients from a group of 46, in whom repackaged bevacizumab in individual aliquots from two vials from the same batch were used. All surgical procedures were performed using standard sterile techniques in the operating room. At each follow-up visit, patients underwent a complete ophthalmological examination including visual acuity assessment, intraocular pressure, biomicroscopy, and posterior fundus examination. Results Ten patients presented sterile endophthalmitis with an onset time of 3.5±1.95 days. The clinical characteristics were mild pain, slight visual loss, conjunctival hyperemia, and various degrees of intraocular inflammation with microhypopyon. All cultures were negative. All patients were managed with topical steroids and antibiotics, except two, in whom, due to severe vitreous cells, intravitreal antibiotics were used. Three patients showed a transient elevation of intraocular pressure. Only 50% of the patients regained a visual acuity equal or better to the baseline visual acuity on file. Conclusion The increasing number of intravitreal injections of bevacizumab applied every day, due to its widespread acceptance, might be one reason why the number of cases of sterile endophthalmitis is rising.

    2015-01-01

    Full Text Available Introduction Hydrops Fetalis is a serious condition in fetal period, characterized by the presence of serous fluid accumulation in at least two potential spaces in fetus including pleural effusion, pericardial effusion, and ascites. The incidence of hydrops fetalis is one per 2500-3000 pregnancies. This condition is followed by different diseases. Fetal hemolytic anemia and its hypoxemia due to hydrops fetalis are potentially life or function threatening. Mortality rate is 50-90%; this poor prognosis is improving with advances in prenatal and medical treatment.                   Methods and Materials This study performed on patients’ records with hydrops fetalis diagnosis in one of the neonatal referral and academic center, Vali-e-Asr Hospital Tehran, the capital of Iran from 2003 to 2010. Etiology, prognosis, and frequency of Hydrops fetalis in newborns were evaluated. Results Out of 10878 cases, 0.35% was born with hydrops fetalis:18.42% immune [Rh incompatibility  (%85.71, Kell antigen system(%14.29 ] and 81.58% non-immune. Conclusion The rate of hydrops due to Rh incompatibility is significant in our center (85.71%, however, it is unusual in most of medical centers all over the world.

    Children’s blood lead concentrations have been closely monitored over the last two decades in the United States. The bio-monitoring surveillance data collected in local agencies reflected the local temporal trends of children’s blood lead levels (BLLs). However, the analysis and modeling of the long-term time series of BLLs have rarely been reported. We attempted to quantify the long-term trends of children’s BLLs in the city of Syracuse, New York and evaluate the impacts of local lead poisoning prevention programs and Lead Hazard Control Program on reducing the children’s BLLs. We applied interrupted time series analysis on the monthly time series of BLLs surveillance data and used ARMA (autoregressive and moving average) models to measure the average children’s blood lead level shift and detect the seasonal pattern change. Our results showed that there were three intervention stages over the past 20 years to reduce children’s BLLs in the city of Syracuse, NY. The average of children’s BLLs was significantly decreased after the interventions, declining from 8.77μg/dL to 3.94μg/dL during1992 to 2011. The seasonal variation diminished over the past decade, but more short term influences were in the variation. The lead hazard control treatment intervention proved effective in reducing the children’s blood lead levels in Syracuse, NY. Also, the reduction of the seasonal variation of children’s BLLs reflected the impacts of the local lead-based paint mitigation program. The replacement of window and door was the major cost of lead house abatement. However, soil lead was not considered a major source of lead hazard in our analysis. PMID:28182688

  10. Assessing Changes in Fisheries Using Fishers' Knowledge to Generate Long Time Series of Catch Rates: a Case Study from the Red Sea

    Directory of Open Access Journals (Sweden)

    Dawit Tesfamichael

    2014-03-01

    Full Text Available The data requirements for most quantitative fishery assessment models are extensive, and most of the fisheries in the world lack time series of the required biological and socioeconomic data. Many innovative approaches have been developed to improve data collection for fisheries. We explored the use of data from fishers' interviews to estimate time series of approximate "best" catch rates. A total of 472 standardized interviews were conducted with 423 fishers along the southern Red Sea coast recording the best catch recalled and the change in average catch rates throughout the fishing career of interviewees. The results showed a decline of best catch rates in all fisheries, ranging from 4% to 10% per year for more than 50 years. The estimated rates of decline of the typical catch were higher for fishers who started fishing in recent years, suggesting that the resource base is declining, in concordance with other indicators. It is suggested that analysis of approximate data, quickly acquired at low cost from fishers through interviews, can be used to supplement other data-recording systems or used independently to document the changes that have occurred in the resource base over a lifetime of fishing. The results can be used to guide the assessment and management of resources to conserve ecosystems and livelihoods.

    Full Text Available This paper describes the spatial and temporal distribution of cases, demographic characteristics of patients, and clinical manifestations of Zika virus (ZIKV during the 2016 outbreak in Grenada. The first reported case was recorded in St. Andrew Parish in April, and the last reported case was seen in November, with peak transmission occurring in the last week of June, based on test results. Data were collected from a total of 514 patients, of whom 207 (40% tested positive for ZIKV. No evidence was found that testing positive for ZIKV infection was related to age, gender, or pregnancy status. Clinical presentation with rash (OR = 2.4, 95% CI = 1.5 to 3.7 or with lymphadenopathy (OR = 1.7, 95% CI = 1.0 to 2.9 were the only reported symptoms consistent with testing positive for ZIKV infection. During the Zika outbreak, the infection rate was 20 clinical cases per 10,000 in the population compared to 41 cases per 10,000 during the chikungunya outbreak in Grenada in 2014 and 17 cases per 10,000 during the dengue outbreak in 2001-2002. Even though the country has employed vector control programs, with no apparent decrease in infection rates, it appears that new abatement approaches are needed to minimize morbidity in future arbovirus outbreaks.

    Our objective was to systematically analyse the first series of cases of amyotrophic lateral sclerosis (ALS) in Minas Gerais and to review the Brazilian literature about clinical studies in ALS. This was a cross-sectional and descriptive study of a consecutive series of patients with probable or defined sporadic ALS according to the Awaji criteria, followed at two referral centres of Belo Horizonte (South-east Brazil). Patients underwent full clinical assessment. Comparisons of patient subgroups according to disease duration and initial presentation were performed. A systematic review was performed about Brazilian clinical studies in ALS. Results showed that of the 61 enrolled patients the male/female ratio was 1.6:1. The mean age at onset of symptoms was 54.9 years (SD ± 11.4). Mean age at diagnosis was 56.3 years (SD ± 11.1). Regarding the initial form of presentation, 43 cases (70.5%) were spinal, 12 cases (19.7%) were generalized and six cases (9.8%) were bulbar. Eight studies were found in the systematic review. In conclusion, the profile of our sample was similar to other national and international series, except for fewer cases of bulbar ALS in our series. There are few clinical studies of ALS in Brazil. The national data of prevalence and incidence are still uncertain.

    Full Text Available Abstract Background Rapidly destructive arthrosis of the hip is a rare and incompletely understood disorder with scarce literature about variations in natural history within a population. Methods A series of cases from North Wales with rapid progressive joint destruction and extensive subchondral bone loss in the femoral head and acetabulum are presented. Radiographic findings mimicked those of other disorders such as septic arthritis, rheumatoid and seronegative arthritis, primary osteonecrosis with secondary osteoarthritis, or neuropathic osteoarthropathy, but none of the patients had clinical, pathologic, or laboratory evidence of these entities. Results Rapid progression of hip pain and disability was a consistent clinical feature. The average duration of symptoms was 1.4 years. Radiographs obtained at various intervals before surgery (average 14 months in 18 patients documented rapid hip destruction, involvement being unilateral in 13 cases. All patients underwent total hip arthroplasty, and osteoarthritis was confirmed at pathologic examination. Conclusion The authors postulate that these cases represent an uncommon subset of osteoarthritis and regular review, both clinically and radiologically, are required to assess speed of progression and prevent rapid loss of bone stock without the surgeon being aware. These cases are unsuitable for being placed on long waiting list due to technical difficulties in delayed surgery and compromised outcome following surgery.

    We have conducted a case study to investigate the performance of support vector machine, multivariate adaptive regression splines, and random forest time series methods in snowfall modeling. These models were applied to a data set of monthly snowfall collected during six cold months at Hamadan Airport sample station located in the Zagros Mountain Range in Iran. We considered monthly data of snowfall from 1981 to 2008 during the period from October/November to April/May as the training set and the data from 2009 to 2015 as the testing set. The root mean square errors (RMSE), mean absolute errors (MAE), determination coefficient (R 2), coefficient of efficiency (E%), and intra-class correlation coefficient (ICC) statistics were used as evaluation criteria. Our results indicated that the random forest time series model outperformed the support vector machine and multivariate adaptive regression splines models in predicting monthly snowfall in terms of several criteria. The RMSE, MAE, R 2, E, and ICC for the testing set were 7.84, 5.52, 0.92, 0.89, and 0.93, respectively. The overall results indicated that the random forest time series model could be successfully used to estimate monthly snowfall values. Moreover, the support vector machine model showed substantial performance as well, suggesting it may also be applied to forecast snowfall in this area.

    Shanghai Pudong International airport is one of the three major international airports in China. The airport is located at the Yangtze estuary which is a sensitive belt of sea and land interaction region. The majority of the buildings and facilities in the airport are built on ocean-reclaimed lands and silt tidal flat. Residual ground settlement could probably occur after the completion of the airport construction. The current status of the ground settlement of the airport and whether it is within a safe range are necessary to be investigated. In order to continuously monitor the ground settlement of the airport, two Synthetic Aperture Radar (SAR) time series, acquired by X-band TerraSAR-X (TSX) and TanDEM-X (TDX) sensors from December 2009 to December 2010 and from April 2013 to July 2015, were used for analyzing with SBAS technique. We firstly obtained ground deformation measurement of each SAR subset. Both of the measurements show that obvious ground subsidence phenomenon occurred at the airport, especially in the second runway, the second terminal, the sixth cargo plane and the eighth apron. The maximum vertical ground deformation rates of both SAR subset measurements were greater than -30 mm/year, while the cumulative ground deformations reached up to -30 mm and -35 mm respectively. After generation of SBAS-retrieved ground deformation for each SAR subset, we performed a joint analysis to combine time series of each common coherent point by applying a geotechnical model. The results show that three centralized areas of ground deformation existed in the airport, mainly distributed in the sixth cargo plane, the fifth apron and the fourth apron, The maximum vertical cumulative ground subsidence was more than -70 mm. In addition, by analyzing the combined time series of four selected points, we found that the ground deformation rates of the points located at the second runway, the third runway, and the second terminal, were progressively smaller as time goes by

    Congenital diaphragmatic hernia is a major malformation occasionally found in newborns and babies. Congenital diaphragmatic hernia is defined by the presence of an orifice in the diaphragm, more often to the left and posterolateral, that permits the herniation of abdominal contents into the thorax. The aim of this case series is to provide information on the presentation, diagnosis and outcome of three patients with late-presenting congenital diaphragmatic hernias. The diagnosis of congenital diaphragmatic hernia is based on clinical investigation and is confirmed by plain X-ray films and computed tomography scans. In the present report three cases of asymptomatic abdominal viscera herniation within the thorax are described. The first case concerns herniation of some loops of the large intestine into the left hemi-thorax in a 75-year-old Caucasian Italian woman. The second case concerns a rare type of herniation in the right side of the thorax of the right kidney with a part of the liver parenchyma in a 57-year-old Caucasian Italian woman. The third case concerns herniation of the stomach and bowel into the left side of the chest with compression of the left lung in a 32-year-old Caucasian Italian man. This type of hernia may appear later in life, because of concomitant respiratory or gastrointestinal disease, or it may be an incidental finding in asymptomatic adults, such as in the three cases featured here. Patients who present with late diaphragmatic hernias complain of a wide variety of symptoms, and diagnosis may be difficult. Additional investigation and research appear necessary to better explain the development and progression of this type of disease.

    found in 65 patients based on X-rays, 80 patients based on CT scan and 83 patients based on intraoperative findings. Comminution was mainly identified during surgery; it was medial in 34 % of cases, posterior in 22 % and posteromedial in 21.8 %. In the current study, 75.4 % of fractures were complex and unstable, with medial and/or posterior comminution present in three-quarters of these fractures. X-ray assessment underestimates posterior comminution and the complexity of the fracture line and was not very reproducible. The current results of this study suggest that comminution contributes to instability and that this finding is not taken into account in the AO classification, which is not well suited for this type of fracture and raises the question of how to best evaluate and treat these fractures. Prospective diagnostic study, Level III.

    The objective of this study is to review the maternal and neonatal morbidity and mortality associated with six or more caesarean section (CS). We conducted a retrospective chart review, at King Abdulaziz University Hospital (KAUH) in Jeddah, for all patients admitted between 2000 through 2010 and identified five patients having more than six CS deliveries. Deliveries occurred in the ranges of 31-38 weeks, from which four cases required emergency CS. There were two cases in the series with a placenta previa. There was a single case of uterine dehiscence. Only one case required a blood transfusion and was complicated with a placenta accreta, bladder injury, urinary tract infection, and prolonged maternal hospital stay with neonatal intensive care unit (NICU) admission. All cases had moderate to severe adhesion intra-operatively. Operative time was long in all cases with a range 55-106 min. One of the five cases had a postoperative wound infection. Finally, none of the current series showed fetal or maternal mortalities. The long-term complications associated with CS should be discussed with patients in the first and subsequent pregnancies. This case series highlighted the outcomes in these unique cases of higher order caesareans.

    Dental implants have evolved as a standard of care for replacement of missing teeth. Though this treatment modality promises a high level of patient satisfaction and success, it cannot be performed in all cases. Apart from medically compromised patients, implant use is also restricted whenever there is limited available bone volume at the edentulous site. An example includes the mandibular incisor, the maxillary lateral incisor region, and other sites with reduced interdental spacing and atrophic edentulous maxillary and mandibular ridges. Bone volume at some of these sites can be increased by suitable augmentation procedure for placement of a regular diameter implant (3.75 to 4.2 mm). But many a times such procedure cannot be undertaken either due to financial constraint, risk of subjecting the patient to additional surgical procedure, added time factor, or guarded prognosis of the grafted site. In such cases, mini-implants can be used. In this case series, mini-implants (2.5 to 3 mm) were used to replace teeth in all mouth quadrants and to retain a mandibular overdenture in a compromised case. The implants served well at all the sites with minimal bone loss and a high level of patient satisfaction. Mini-implants hold the potential to serve as an alternate to regular diameter implants in certain situations. Preferably they should be used in multiples to retain fixed dental prostheses and might serve as an efficient, low-cost solution for retaining overdentures in selected cases. © 2015 by the American College of Prosthodontists.

    Full Text Available Glaucoma management in pregnant patients is a real challenge, especially when the glaucoma is not controlled with medications. We report the results of 6 incisional glaucoma surgeries for the management of medically uncontrolled glaucoma patients during pregnancy. This retrospective, case series was conducted on the 6 eyes of 3pregnant patients with uncontrolled glaucoma using maximum tolerable medications. Details of the glaucoma surgical management of these patients as well as their postoperative care and pregnancy and clinical outcomes on longitudinal follow-up are discussed. All 3 patients had juvenile open-angle glaucoma and were on various anti-glaucoma medications, including oral acetazolamide. The first case described underwent trabeculectomy without antimetabolites in both eyes because of uncontrolled intraocular pressure with topical medications. The surgery was done with topical lidocaine jelly and subconjunctival lidocaine during the second and third trimesters. The second patient had an Ahmed valve implantation in both eyes during the second and third trimesters because of uncontrolled IOP with topical medications and no response to selective laser trabeculoplasty. Surgery was done with topical tetracaine and subconjunctival and sub-Tenon’s lidocaine. The third case had a Baerveldt valve implantation under general anesthesia in the second trimester. In selected pregnant glaucoma patients with medically uncontrolled intraocular pressure threatening vision, incisional surgery may lead to good outcomes for the patient with no risk for the fetus.

    Full Text Available Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

    Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

    Synovial sarcoma is a rare soft tissue sarcoma with poor long-term prognosis due to late recurrence and metastasis. Synovial sarcoma arises in less than 6% from the shoulder. As a result, there is limited information in the literature about synovial sarcoma of the shoulder (SSS). We included all patients treated for SSS at our institution between 1985 and 2013. Medical charts were retrospectively reviewed to collect demographics, information about the clinical course, and outcome. This subgroup was compared to our institution's entire synovial sarcoma patient cohort and the data in the published literature. SSS Patients presented most commonly with pain and a growing mass; the majority of tumors were grade 2 and measured greater than 5 cm. 43% (7) of SSS patients developed metastatic disease and 36% (5) had died at a median follow-up of 64 months (36-127); SSS 5-year survival (83.3%) was higher in our series than in the general literature (57-75%). We found better prognosis in patients with synovial sarcoma of the shoulder than expected based on the current literature. The clinical behavior of synovial sarcoma in the shoulder is closer to that of synovial sarcoma in the extremities than the trunk. Level IV, Case Series. © 2017 Wiley Periodicals, Inc.

    Full Text Available Objective To report the clinical and neuroimaging findings in a case series of vascular parkinsonism (VP. Methods Seventeen patients with VP were evaluated with motor, cognitive, and neuroimaging standardized tests and scales. Results All patients had arterial hypertension. Ten patients were male and the mean age of the whole sample was 75.8±10.1 years. The mean age of parkinsonism onset was 72.2±10.0 years. Common clinical features were urinary incontinence (88.2%, lower limb parkinsonism with freezing of gait and falls (82.3%, and pyramidal signs (76.4%. The mean Unified Parkinson’s Disease Rating Scale (UPDRS and Hoehn-Yahr scores were 72.5±21.6 points and 3.3±0.9 points, respectively. Sixteen (94.1% patients had freezing of gait and executive dysfunction. Twelve (70.5% patients had probable vascular dementia. The mean dose of levodopa was 530.9 mg/day. Unresponsiveness to the drug was confirmed by a 6.9 mean point reduction in the UPDRS score after the “practically defined off” test. Conclusion This series provides a profile of VP with predominant lower-limb involvement, freezing of gait and falls, pyramidal signs, executive dysfunction, concomitant vascular dementia, and poor levodopa response.

    This case series presents our experience with burns sustained while manufacturing illegal drugs. All adult burn admissions in an 18-month period were retrospectively reviewed. All patients suspected of sustaining burns from illegal drug manufacture were contacted. Information regarding the burn mechanism was sought. Nine of the 64 adult burn admissions were caused by explosions during the manufacture of cannabis oil. Young males with hand and face burns were heavily represented. First-aid treatment was often ignored in favor of hiding incriminating evidence. Only two patients gave honest admission histories. Illegal drug manufacture is becoming more common as synthetic drugs become more consumer desirable. Burns sustained may be thermal and/or chemical. Dishonest patient histories negatively influence burn management. A high level of suspicion is required for diagnosing and treating burns from illegal drug manufacture. Public education is unlikely to be effective as the financial rewards outweigh the perceived risks.

    The most common sites of metastatic differentiated thyroid cancer are the neck lymph nodes, while distant metastases typically involve the lungs, the bones, and less frequently the brain. Uncommon metastatic sites include the liver, adrenal gland, kidney, pancreas, and skin. The epidemiological aspects of thyroid metastases in rare sites are largely unknown and their identification could have a significant impact on patients management. A mini-series of unusual metastatic sites of thyroid carcinoma is proposed as a contribution to current knowledge on anatomopathological characteristics and clinical outcome. Of the six cases that were assessed, the metastases were the following: skin metastases (2), skin and pancreas metastases (1), renal metastasis (1), adrenal metastasis (1), and liver metastasis (1). In our experience, metastases in rare sites do not always represent a negative prognostic factor for disease outcome. In fact they can occur as single distant lesion and if surgically resectable, their treatment can also lead to local disease remission.

  8. Pink esthetics in periodontics - Gingival depigmentation: A case series

    Full Text Available Smile expresses a feeling of joy, success, sensuality, affection, and courtesy, and reveals self-confidence and kindness. The harmony of the smile is determined not only by the shape, the position, and the color of the teeth, but also by the gingival tissues. Although melanin pigmentation of the gingiva is completely benign and does not present a medical problem, complaints of "black gums" are common, particularly in patients having a very high smile line. Thus, perio-esthetic treatment modalities strive to achieve a harmonious inter-relationship of the pink with white, which is imperative of all treatment procedures. For depigmentation of gingival, different treatment modalities have been reported, such as bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery, and laser. In the present case series, scraping, electrosurgery, and diode laser have been tried for depigmentation, which are simple, effective, and yield good results, along with good patient satisfaction.

    Environmental change can shift the phenotype of an organism through either evolutionary or nongenetic processes. Despite abundant evidence of phenotypic change in response to recent climate change, we typically lack sufficient genetic data to identify the role of evolution. We present a method of using phenotypic data to characterize the hypothesized role of natural selection and environmentally driven phenotypic shifts (plasticity). We modeled historical selection and environmental predictors of interannual variation in mean population phenotype using a multivariate state-space model framework. Through model comparisons, we assessed the extent to which an estimated selection differential explained observed variation better than environmental factors alone. We applied the method to a 60-year trend toward earlier migration in Columbia River sockeye salmon Oncorhynchus nerka, producing estimates of annual selection differentials, average realized heritability, and relative cumulative effects of selection and plasticity. We found that an evolutionary response to thermal selection was capable of explaining up to two-thirds of the phenotypic trend. Adaptive plastic responses to June river flow explain most of the remainder. This method is applicable to other populations with time series data if selection differentials are available or can be reconstructed. This method thus augments our toolbox for predicting responses to environmental change.

    This retrospective case series reports on a group of patients with multifocal juvenile osteochondritis dissecans (MJOCD) of the knee and discusses demographic data, lesion location, stage, and treatment results. Records of patients identified with MJOCD of the knee at a single institution were retrospectively reviewed. Demographic, radiographic, and surgical results were recorded. Lesions were descriptively classified and lesions undergoing surgical treatment were staged. Results of operative and nonoperative treatment were recorded. Fifty-nine lesions were identified in 28 patients who met the inclusion criteria. There were 22 males (78%) and 6 females (21%). Average age was 11.8 years (males, 6 to 17; females, 10 to 14). Thirty-six (61%) lesions were on the medial femoral condyle (MFC), 19 (32%) on the lateral femoral condyle, 2 (3%) on the trochlea, 1 (2%) on the patella, and 1 (2%) on the anteromedial tibial plateau. Forty-four (74%) lesions required operative treatment. Of the 32 stable lesions managed surgically, 25 (78%) achieved healing with operative treatment. All 12 unstable lesions identified were managed surgically with 5 (41%) healed after the initial operation. Lesions located on the MFC had a significantly higher rate of healing (89%) compared with lateral femoral condyle lesions (37%) (P1 identified lesion occurring in the same or the contralateral knee. Prevalence of MJOCD of the knee is unknown. A high percentage of these patients require surgical intervention with only one quarter of stable lesions healing with conservative treatment. Healing rates of stable lesions after surgery was nearly twice that of unstable lesions undergoing surgical intervention. Lesions located on the MFC healed at a statistically significant greater rate than other locations within the knee. Sex, age, and associated discoid menisci had no effect on healing prognosis. Level IV-case series.

In the last few years, there have been an increasing number of reports about sterile intraocular inflammation and intraocular pressure elevations after intravitreal bevacizumab. In the following case series, we describe the clinical presentation and outcomes of ten consecutive cases of patients developing mild-to-severe sterile intraocular inflammation after intravitreal bevacizumab and their management. Methods: This report presents a retrospective case series. We reviewed the medical records of ten consecutive patients from a group of 46, in whom repackaged bevacizumab in individual aliquots from two vials from the same batch were used. All surgical procedures were performed using standard sterile techniques in the operating room. At each follow-up visit, patients underwent a complete ophthalmological examination including visual acuity assessment, intraocular pressure, biomicroscopy, and posterior fundus examination. Results: Ten patients presented sterile endophthalmitis with an onset time of 3.5±1.95 days. The clinical characteristics were mild pain, slight visual loss, conjunctival hyperemia, and various degrees of intraocular inflammation with microhypopyon. All cultures were negative. All patients were managed with topical steroids and antibiotics, except two, in whom, due to severe vitreous cells, intravitreal antibiotics were

    Citizen science and crowdsourcing are relatively unfamiliar terms to the general public, including parents, children and teachers, as seen in focus groups convened by the NSF-funded THE CROWD & THE CLOUD public television series. Once aware, however, of the potential of today's citizen science—often relying on smartphones, apps and innovative sensors—both citizens and professional scientists become excited and seek to learn more. CROWD & CLOUD, premiering on PBS stations in April 2017, hosted by former NASA Chief Scientist Waleed Abdalati, and streaming at CrowdAndCloud.org, features a wide range of projects supported by NASA, NOAA, USGS, EPA and other Federal agencies. Some, such as EyesOnALZ, a startup which aims to accelerate research on Alzheimer's disease, adapt a crowdsourcing model first developed to help analyze data returned by NASA's Stardust spacecraft. Early results from its "StallCatchers" puzzle-game show both high quality data and have been shown to cut one year's worth of academic labor down to one month of effort by "the crowd." While longstanding citizen science projects such as Audubon's Christmas Bird Count (starting in 1900) have proven their worth, Smartfin—embedding sensors in surfboard fins—is taking advantage of recent technical innovations to track sea surface temperatures and ocean acidification, with their accuracy validated by the Scripps Institution of Oceanography. The NASA-supported GLOBE Observer mosquito habitat mapper project uses a $6 microscope attached to a smartphone to aid in species identification. Some projects tap adult volunteers, but many, such as USGS's Nature's Notebook, also appeal to youngsters. In Albuquerque local teens track invasive species and help refuge managers, usefully supplementing the sole salaried ranger. In the Rockaways, New York, high school students plant pollinator gardens and promote ecosystem resilience following Superstorm Sandy. This presentation will feature short videos demonstrating

    Full Text Available Introduction: Gingival enlargement (GA is a benign condition of the oral cavity that is characterized by the excessive growth of the gingiva in mass and volume. This lesion is not only caused by hereditary factors or poor oral hygiene, but also by the intake of medications, including antihypertensive, anticonvulsant and immunosuppressive drugs. Objective: To sensitize the prevention or early care in patients with pathologies that merit the use of antihypertensive and anticonvulsants in conjunction with the dentist, to treat or avoid the drug-induced gingival enlargement (DIGE. Materials and methods: A series of clinical cases of patients with gingival enlargement by various drugs are reported, including Phenytoin, Amlodipine and Nifedipine. Periodontal and gingivectomy hygienic phase measures were applied to obtain better effects. Results: Satisfactory results were obtained with a considerable decrease in DIGE. Conclusions: The integral management is important in conjunction with the treating physician to follow up the drug that can be generating gingival enlargement. It is necessary to employ an initial approach with strategies of periodontal hygiene, and in severe cases and, as last resort, the periodontal surgery with gingivectomy and gingivoplasty.

    2016-01-01

    Full Text Available Background. Pyogenic granuloma is a reactive tumor-like lesion commonly affecting the oral cavity. These lesions usually appear as localized solitary nodule with a sessile or pedunculated base and colour varying from red, purplish, or pink, depending on the vascularity of the lesion. Pyogenic granuloma shows predilection for gingiva and is usually slow growing, but at times it shows rapid growth. The natural course of this lesion can be categorized into three distinct phases, namely, (i cellular phase, (ii capillary phase/vascular phase, and (iii involutionary phase. Histopathologically, pyogenic granuloma is classified into lobular capillary hemangioma (LCH and non-lobular capillary hemangioma (non-LCH. Case Presentation. In this series, four cases (varied age groups and both genders of pyogenic granuloma showing varying histopathological presentation in relation to its clinical course have been described. The lesion in its early phase reveals diffuse endothelial cells, with few budding into capillaries. Among the capillary phase, the LCH type shows numerous blood vessels organized into lobular aggregates whereas the non-LCH type does not show any such organization and resembles granulation tissue. The involutionary phase shows healing of the lesion and is characterized by extensive fibrosis in the connective tissue. Conclusion. In conclusion, knowledge of the various histopathological presentation of this lesion is necessary for proper identification.

The ratio of doctors is 1:75,000 inhabitants. Five ophthalmologists took part in the last deployment in November. Local staff had previously selected the patients from the rural areas, as well as in Lodwar, the capital of the district. Of the 371 patients who attended the clinic, 128 required surgery. To describe the pediatric population attended to in the last «Turkana Eye Project» Camp. Description of the ophthalmic pathologies of the children seen in the clinic in this surgical camp, and the diagnostic and therapeutic options according to the limitations of the environment. Of the 371 patients, 54 were younger than 15 years old (14.5%). Four children had surgery (3.25% of the 128 patients). In 2 more cases surgery was the indicated but not performed. Therefore, of the total of 54 cases, 6 could be considered as surgical (11.1%), and 17 suffered ophthalmic problems other than refraction defects, or mild ocular surface pathologies: traumatic cataracts, neuropathies, impetigo, exophthalmos, retinal dystrophies, dermoid cysts, or nyctalopia. The etiology was traumatic in four of the 17 children (23.5%). Surgical camps are increasing in the developing countries. They are usually focused on particular pathologies, such as cataracts or trachoma. Our case series shows the importance of pediatric teams and the need to be prepared to face complex pediatric pathologies. Copyright © 2012 Sociedad Española de Oftalmología.

    Full Text Available Eosinophilic meningoencephalitis (EM is a rare type of meningoencephalitis. The objective of this report is to describe a series of EM identified in a specific geographic area over a short period of time. Materials and Methods: This series of cases are described from a neurological center in Central Kerala occuring in the period between February 2004 and June 2006. Results: During this period we had identified ten patients (eight males and two females with EM. Their mean age was 37.1 years (range 15-60 years. Main symptomatologies were fever, severe headache, body pain, abdominal pain and arthralgia. One patient was in akinetic rigid state with coma. All patients had peripheral eosinophilia. The cerebrospinal fluid (CSF of all patients showed eosinophilic pleocytosis. The mean CSF white cell count was 588 cells. CSF differential count showed 50-70% eosinophils. CSF glucose levels were normal but proteins were markedly raised (mean CSF protein was 180 mg/dl. MRI brain showed T2 hyperintensities diffusely in periventricular white matter in the comatose patient. Contrast enhanced CT scan of the brain was normal in others. All eight male patients gave history of eating "raw flesh of Monitor Lizard" (Iguana some three to fourteen days prior to the onset of symptoms. There was no such history for the female patients. Considering the history of exposure and eosinophilic meningitis we suspected a meningoencephalitis with Angiostrongylus cantonensis and treated them with albendazole, steroid and other supportive measures. All of them recovered. Conclusion: Eosinophilic meningitis (EM is a rare condition and in this locality, a CNS infection with Agiostrongylus cantonensis is highly likely. AC is a parasite in monitor lizard. Human infection occurs from consumption of uncooked flesh or blood of infected lizards. Physicians need to maintain a high index of suspicion and enquire for any exposure to uncooked meat or blood of monitor lizard when faced with EM

    To compare the chronic ocular manifestations in Stevens-Johnson syndrome and toxic epidermal necrolysis patients from a 15-year cohort. All SJS and TEN patients admitted to our burn intensive care unit between 1999 and 2014 were invited for assessment. Slit-lamp examination was performed, and ocular condition was graded according to the Sotozono scoring System, which depended on the extent of cornea, conjunctiva and lid involvement. Tear osmolarity was also measured. A total of 18 SJS and 4 TEN cases with an average of 92 and 135 months from disease onset were included. The average age of onset was 46.4 ± 16.6 in SJS and 43.5 ± 19.3 in TEN patients. The LogMAR visual acuity was 0.209 ± 0.591 in SJS and 0.489 ± 0.688 in TEN patients (p = 0.048). The average total Sotozono score was 3.75 ± 7.32 in SJS and 6.88 ± 9.49 in TEN (p = 0.358). Neither the age of onset (p = 0.787), length of follow-up (p = 0.256) nor disease type (SJS vs TEN, p = 0.188) predicted the Sotozono score. There was a statistically significant correlation between Sotozono score and LogMAR VA (r s  = 0.437, p = 0.003). The average total Sotozono score was higher in the TEN group than in the SJS group, but the difference was not statistically significant. Nevertheless, the score correlated with the visual acuity which was statistically worse in the TEN group.

    Full Text Available Purpose: To study the clinical presentation and treatment outcome of patients with ocular cysticercosis in southern India. Methods: This study included 10 patients who were diagnosed to have ocular or adnexal cysticercosis over a period of one year in Pondicherry, India. The clinical presentation, results of investigation and treatment outcome of the cases were analysed retrospectively. Results: Age of these patients ranged from 12 to 55 years. Four presented with loss of vision, two with a swelling in the eyelid, one with proptosis, one with diplopia and two with conjunctival involvement. ELISA for cysticercus antibodies in serum was positive in all cases. Albendazole and prednisolone were given for the treatment of these cases. Two patients responded well to treatment and were completely cured of the disease. There was partial improvement in 6 cases. Surgery in the form of excision was performed in two cases following a course of medical therapy. There was no significant change in visual acuity in eyes with intraocular cysticercosis following treatment. Conclusion: Ultrasonography B scan and ELISA for anticysticercal antibodies help to establish the diagnosis of ocular cysticercosis. A combination of oral albendazole and corticosteroids is found to be effective in confirmed cases. Intraocular cysticercosis is associated with a poor prognosis for vision.

    Turkey hosts around 3 million Syrian refugees which is more than any other country in the world. Along with some other adaptation issues like cultural, language, and economic difficulties, significant problems in managing medical problems, chronic diseases like cancer in particular, have to be fixed. However, there are few studies which explore main patient and clinicopathological characteristics in Syrian refugees with cancer. The purpose of this study was to highlight the aforementioned characteristics along with management issues after cancer diagnosis of these patients. This study was designed as a hospital-based retrospective observational case-series study of 134 Syrian refugees cancer patients between 2015 and 2017. The patient median age was 47.5 years (range 18- 80). Out of the 134, 102 (76.1%) were female. The most common cancer types were breast (n=57, 42.5%) and gynecological cancers (n=14, 10.4%). The majority of patients were diagnosed at advanced stage (n=60, 44.8%). There were 91 (67.9%) and 43 (32.1%) patients admitted to our center from refugee camps and staying in a house, respectively. The median follow-up was 14 months (range 1-111) and 11 (8.2%) patients died. One and two-year survival rate of the whole group were 93% and 86%, respectively. There were 12 (9%) patients with grade 3-4 hematological and non-hematological toxicities. Neutropenia was the most common grade 3-4 toxicity (n=8, 6%). The patients staying in refugee camp (n-91) or in a house (n=43) finished all planned cycles of chemotherapy with a rate of 71% (n=65) and 79% (n=34), respectively. Statistical analysis failed to show significant relationship between the staying site (either camp or house), chemotherapy compliance rate, grade 3-4 toxicities with p=0.347 and p=0.09, respectively. Our results revealed that breast cancer and gynecological cancers were the most common cancer types which are good candidates for cancer screening. Unfortunately, the majority of patients had cancer

     There are few studies on possible effects of physiotherapy for adults with muscular dystrophy. The aim of this study was to examine if treatment based on the Bobath concept may influence specific gait parameters in some of these patients.   A single-subject experimental design with A-B-A-A phases was used, and four patients, three with limb-girdle muscular dystrophy (LGMD) and one with fascioscapulohumeral muscular dystrophy (FSHD), were included. The patients had 1 hour of individually tailored physiotherapy at each working day for a period of 3 weeks. Step length, step width and gait velocity were measured during the A-B-A-A phases by use of an electronic walkway. Walking distance and endurance were measured by use of the '6 minute walk test'.  . The three LGMD patients, who initially walked with a wide base of support, had a narrower, velocity-adjusted step width after treatment, accompanied with the same or even longer step length. These changes lasted throughout follow-up. Moreover, two of the patients were able to walk a longer distance within 6 minutes after the treatment period. The fourth patient (with FSHD) had a normal step width at baseline, which did not change during the study.   The results indicate that physiotherapy treatment based on the Bobath concept may influence the gait pattern in patients with LGMD. However, in order to evaluate the effectiveness of physiotherapy to patients with muscular dystrophies, we call for larger studies and controlled trials. Copyright © 2010 John Wiley & Sons, Ltd.

    Immediate loading of dental implants is increasingly gaining recognition as a viable option for both patient and clinician. The aim of this study was to evaluate the results of 55 patients in a clinical investigation of immediate functional loading of Brånemark System implants (Nobel Biocare USA, Yorba Linda, CA) in edentulous maxillas. Its further purpose is to suggest a reliable and evidence-based protocol for immediate implant loading of full-arch prostheses in the maxilla. A total of 552 Brånemark System implants were placed in immediate extraction or healed sites; a mean number of 10 implants were placed per patient. The healthy subjects in need of full-arch maxillary implant reconstruction were treated between December 1999 and February 2004; 522 of the 552 implants were immediately loaded with screw-retained all-acrylic fixed prostheses at the time of surgery. Approximately 4 to 6 months later, the 30 submerged implants were uncovered, and a definitive metal-reinforced prosthesis was delivered to each patient. The immediately loaded implant cumulative survival rate was 99.0% for these patients. The prosthesis survival rate was 100%. The results of this prospective study of full-arch maxillary immediate loading suggests that this protocol is suitable for most patients in need of full maxillary implant reconstruction. The protocol, as shown in this study, is highly successful in providing a lasting state of osseointegration as the foundation for long-term stability of screw-retained fixed prostheses.

    Selective mutism (SM) is characterised by limited or a lack of speech in selected social settings. Recent reviews suggest that cognitive-behavioural therapy (CBT) is an effective and promising treatment approach for SM. However, there is still a lack of studies documenting the applicability of CBT for SM in diverse populations. The goal of the present study was to examine the use of a web-based CBT programme ('Meeky Mouse') among Singaporean children diagnosed with SM. Five children with SM (one boy and four girls aged 6-11 years) participated in the 14-week 'Meeky Mouse' programme, in addition to being prescribed with an unchanged dosage of fluoxetine 10-20 mg daily. The progress made by the children throughout the course of the programme was documented by the therapist. Post treatment, four out of the five children demonstrated improvements in the frequency of speech during therapy sessions at home, in school and at other social situations. Findings from the present study provide support for the use of a web-based CBT programme in improving speech and decreasing the severity of SM among affected children.

    BACKGROUND: In our clinical work, we treat refugees who have been exposed to trauma and who subsequently develop psychotic symptoms. However, the literature does not address the relationship between refugees with depression, post-traumatic stress disorder (PTSD) and psychotic symptoms. Therefore...... the aim of this study is firstly to present a series of cases showing how psychotic symptoms may present in refugees diagnosed with PTSD, and secondly to discuss the underlying explanations of the involved psychopathology. METHODS: The study is based on a presentation of a series of cases. All six cases...... were selected as they fulfilled the following criteria for inclusion: 1) had a refugee background, 2) fulfilled the PTSD (F43.1) diagnosis upon treatment start and 3) revealed psychotic symptoms during treatment. All six were outpatients at the Psychiatric Trauma Clinic for Refugees at Psychiatric...

  11. Time Series of Landscape Fragmentation Caused by Transportation Infrastructure and Urban Development: a Case Study from Baden-Württemberg, Germany

    Full Text Available Landscape fragmentation is increasingly considered an important environmental indicator in the fields of sustainable land use and biodiversity. To set goals for future development and to plan appropriate measures, suitable empirical data on the degree of landscape fragmentation are needed to identify trends and compare different regions. However, there is still a significant lack of data on landscape fragmentation as an indicator, despite the substantial scientific literature on this topic, likely because of confusion over the definition of "fragmentation," questions associated with scale and data issues, and lack of general agreement on a fragmentation measure. This study presents a state-wide quantitative analysis of landscape fragmentation in Baden-Württemberg, Germany, by means of the "effective mesh size" (meff, which characterizes the anthropogenic penetration of landscapes from a geometric point of view and is based on the probability that two randomly chosen points in a landscape are connected, i.e., not separated by barriers such as roads, railroads, or urban areas. Baden-Württemberg is fragmented to a far greater extent than indicated by previous studies. The meff has decreased by 40% since 1930. This development is strongly related to the growing number of inhabitants, the increased use of motorized vehicles, and the hierarchical regional planning system based on the central place theory. To illustrate the suitability of the meff method for environmental monitoring, as a planning instrument and as an assessment instrument for impact assessment studies, we explored several variations of applying the method with regard to choice of fragmenting elements, consideration of noise bands, spatial differentiation (e.g., administrative districts vs. ecoregions, and way of dealing with patches at the boundaries of the reporting units. Depending on the objectives of the investigation (e.g., recreational quality vs. suitability for wildlife

    OBJECTIVES: Zirconia-based prostheses are commonly used for aesthetic crown and fixed restorations, although follow-up data are limited, especially for implant-supported crowns. The aim of this study was to evaluate the three-year clinical results of the installation of 463 zirconia core crowns by a general dental private practice. METHODS: This study followed 142 patients (69 men and 73 women; aged 28-82 years) who had received 248 single crowns (202 tooth-supported, 36 implant-supported) and 225 multiple units of up to six elements (81 tooth-supported, 144 implant-supported). Clinical events, including fracture and loss of retention, secondary caries, and marginal integrity, were recorded. The overall failure rate was computed for the fractured and lost prostheses. Aesthetic, functional, and biological properties were rated, and patient satisfaction was investigated. RESULTS: During the three-year follow-up period, four patients were lost from the study (18 crowns, 4% of the total crowns). Three of the zirconia prostheses suffered fractures in more than three units (11 crowns; one- vs. three-year follow-up, pcemented, and no secondary caries of the abutment teeth were reported. The aesthetic, functional, and biological properties were generally well-rated, and there were no differences between tooth- and implant-supported crowns. The lowest scores were given regarding the anatomical form of the crowns, as some minor chipping was reported. Relatively low scores were also given for the periodontal response and the adjacent mucosa. Overall, patient satisfaction was high. CONCLUSIONS: At the three-year follow-up, the zirconia-core crowns appeared to be an effective clinical solution as they had favorable aesthetic and functional properties. Only the marginal fit of the prostheses should be improved upon. PMID:22189731

    A case series of consecutive patients referred to physical therapy with patellofemoral pain syndrome (PFPS). Physical therapists often treat patients with PFPS, yet there is currently no consensus as to the most effective management strategies. The purpose of this case series is to describe the outcomes of patients referred to physical therapy with PFPS who were treated with a multimodal approach. Five patients were treated with a combination of thrust and nonthrust manipulation directed at the joints of the lower quarter, trunk and hip stabilization exercises, patellar taping, and foot orthotics. Outcome measures used to capture change in patient status included the Numeric Pain Rating Scale, the Kujala Anterior Knee Pain Scale, the Lower Extremity Functional Scale, and the Global Rating of Change. Five patients (median age, 15 years; range, 14-50 years) with a median duration of knee pain for 8 months (range, 3-24 months) were included in this prospective case series. Four (80%) of the 5 patients demonstrated decreased pain and a clinically significant improvement in function. These gains in function were maintained at a 6-month follow-up. Although a cause-and-effect relationship cannot be inferred from a case series, the outcomes achieved by the patients are consistent with studies incorporating manual physical therapy, exercise, patellar taping, and orthotic prescription to the management of conditions of the lower extremity. Further randomized controlled trials should be performed to determine the effectiveness of this multimodal approach for the management of individuals with PFPS.

    Full Text Available Background. Hydrophilic and moderately rough implant surfaces have been proposed to enhance the osseointegration response. Aim. The aim of this study was to compare early changes of stability for two implants with identical macrodesign but with different surface topographies. Materials and Methods. In 11 patients, a total of 22 implants (11 bimodal (minimally rough, control and 11 proactive (moderately rough and hydrophilic, test, Neoss Ltd., Harrogate, UK were immediately placed into fresh extraction sockets and immediately loaded. The peak insertion torque (IT was measured in Ncm at placement. Resonance Frequency Analysis (RFA measurements were made at baseline and 2, 4, 6, and 12 weeks after surgery. Results. The two implant types showed similar IT and RFA values at placement (NS. A dip of RFA values after 2 weeks followed by an increase was observed, where the test implant showed a less pronounced decrease and a more rapid recovery than the control implant. The test implants were significantly more stable than the control ones after 12 weeks. Conclusions. The results from the present study indicated that the hydrophilic and rougher test implant was more resistant to immediate loading and showed a significantly higher stability than the smoother control implant after 12 weeks.

    Dens invaginatus may be seen as a developmental malformation. It is characterized by an invagination of the enamel and dentin, creating a lumen inside the affected tooth, which may extend as deep as the apical foramen. Oehlers Type IIIb is considered the most challenging clinical conditions. The purpose of this study is to discuss the nonsurgical endodontic management of vital and necrotic dens invaginatus Type IIIb cases. Due to the complex anatomical consideration of dens invaginatus Type IIIb, endodontic treatment is extremely technique sensitive. A conservative approach was used in a vital case to treat the invaginated lumen only, to preserve the vitality of the pulp, and a more invasive approach was used in a necrotic case to debride the lumen and necrotic pulp for proper disinfection of the root canal system. Although different, all the approaches were successful. The clinical signs and symptoms were resolved. The vital case remains vital after 19 months, and the recall radiographs were able to show satisfactory periapical healing both in vital and necrotic cases. Due to the highly complex anatomy of dens invaginatus Type IIIb, the decision of preserving the pulp vitality may not be related only to pulpal diagnosis but also to the technical requirements of the treatment. Although very technically sensitive, it may be possible to treat the invaginated lumen exclusively, while preserving the vitality of the pulp. Necrotic cases may require a more aggressive approach to achieve a favorable prognosis.

    Ambient air pollution has been associated with respiratory diseases in children. However, its effects on pediatric pneumonia have not been meta-analyzed. We conducted a systematic review and meta-analysis of the short-term association between ambient air pollution and hospitalization of children due to pneumonia. We searched the Web of Science and PubMed for indexed publications up to January 2017. Pollutant-specific excess risk percentage (ER%) and confidence intervals (CI) were estimated using random effect models for particulate matter (PM) with diameter ≤ 10 (PM 10 ) and ≤2.5 μm (PM 2.5 ), sulfur dioxide (SO 2 ), ozone (O 3 ), nitrogen dioxide (NO 2 ), and carbon monoxide (CO). Results were further stratified by subgroups (children under five, emergency visits versus hospital admissions, income level of study location, and exposure period). Seventeen studies were included in the meta-analysis. The ER% per 10 μg/m 3 increase of pollutants was 1.5% (95% CI: 0.6%-2.4%) for PM 10 and 1.8% (95% CI: 0.5%-3.1%) for PM 2.5 . The corresponding values per 10 ppb increment of gaseous pollutants were 2.9% (95% CI: 0.4%-5.3%) for SO 2 , 1.7% (95% CI: 0.5%-2.8%) for O 3 , and 1.4% (95% CI: 0.4%-2.4%) for NO 2 . ER% per 1000 ppb increment of CO was 0.9% (95% CI: 0.0%-1.9%). Associations were not substantially different between subgroups. This meta-analysis shows a positive association between daily levels of ambient air pollution markers and hospitalization of children due to pneumonia. However, lack of studies from low-and middle-income countries limits the quantitative generalizability given that susceptibilities to the adverse effects of air pollution may be different in those populations. The meta-regression in our analysis further demonstrated a strong effect of country income level on heterogeneity. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The objective of this proof-of-principle study was to examine the potential for improved bone regenerative outcomes in maxillary sinus augmentation procedures when recombinant human platelet-derived growth factor BB (0.3 mg/mL) is combined with particulate anorganic bovine bone mineral. The surgical outcomes in all treated sites were uneventful at 6 to 8 months, with sufficient regenerated bone present to allow successful placement of maxillary posterior implants. Large areas of dense, well-formed lamellar bone were seen throughout the intact core specimens in more than half of the grafted sites. Abundant numbers of osteoblasts were noted in concert with significant osteoid in all sites, indicating ongoing osteogenesis. A number of cores demonstrated efficient replacement of the normally slowly resorbing anorganic bovine bone mineral matrix particles with newly formed bone when the matrix was saturated with recombinant human platelet-derived growth factor BB.

    The cause of nocturnal awakenings in patients with chronic insomnia is rarely researched. This study prospectively assessed the etiology of nocturnal awakenings (subjectively and objectively) among patients with insomnia at a private, community-based sleep medical center. Twenty adult patients with chronic insomnia enrolled between April 2008 and February 2010 met diagnostic criteria for an insomnia disorder, never previously visited a sleep specialist or underwent sleep testing, and reported no classic sleep disordered breathing symptoms. Patients completed validated scales for insomnia, sleepiness, impairment, anxiety, depression, and quality of life, a qualitative interview to assess subjective reasons for awakenings, and a diagnostic sleep study to objectively assess awakenings and their precipitants. Subjective and objective data showed clinically meaningful insomnia, primarily sleep maintenance insomnia. The most common self-reported reasons for awakenings were: uncertain cause (50%), nightmares (45%), nocturia (35%), bedroom distractions (20%), or pain (15%). No patient identified breathing symptoms as a cause. Objectively, 531 awakenings were observed in the total sample, and 478 (90%) were preceded by sleep breathing events (apnea, hypopnea, or respiratory effort-related event). Fifty-three awakenings were caused by other factors (independent leg jerks [7], spontaneous [14], and sleep that was laboratory-induced [32]). Thirty awakenings ≥ 5 min-a duration sufficient to predispose toward an insomnia episode-were each preceded by a breathing event. Among patients with insomnia with no classic sleep breathing symptoms and therefore low probability of a sleep breathing disorder, most of their awakenings were precipitated by a medical condition (sleep disordered breathing), which contrasted sharply with their perceptions about their awakenings

    Episodes of agitation are frequent in intoxicated patients who have a substance use disorder, a psychiatric disorder or both (dual diagnosis). For managing the agitation, it is necessary to act promptly in a safe environment and addressing any underlying etiology. Inhaled loxapine improves symptoms of agitation in adults with psychiatric disorders (eg, schizophrenia) within 10 minutes of administration. Recently, some reports have documented the usefulness of loxapine in dual diagnoses patients with agitation. However, the efficacy of loxapine in intoxicated patients has not been deeply addressed. This report describes a case series of 12 patients (with addiction or dual disorder) who received inhaled loxapine for symptoms of psychomotor agitation during intoxication with different substances (eg, alcohol, cannabis, or cocaine) at 1 center in Spain. Data from 12 patients were reviewed, 5 patients were attended at the emergency room, 4 at the addiction and dual diagnosis unit, and 3 were treated during hospitalization for detoxification. All patients were under effects of substances. They had substance use disorder (including cannabis, cocaine, alcohol, hypnotics, and hallucinogens), and almost all (90%) presented 1 or more psychiatric disorders. One dose of inhaled loxapine was effective in 9 patients (75%), and in 3 patients, a second dose was required. Only mild dizziness was reported in 1 patient after the second dose. The acute agitation was effectively and quickly managed with inhaled loxapine in all intoxicated patients and enabled the appropriate clinical evaluation of the agitated state and the patient's management.

    Headache happens in the majority of patients with Cerebral Venous Thrombosis (CVT) being sometimes the sole manifestation of the disease. Herein we report a case-series of CVT, focusing on headache characteristics. Etiological, clinical, and radiological features of 25 consecutive adult patients with CVT were compiled from August 2005 to December 2013. Diagnosis of CVT was confirmed by brain magnetic resonance imaging and magnetic resonance venography. All patients underwent extensive systematic etiological and genetic work-up at admission. A structured questionnaire about the characteristics of headache was responded by all participants. Headache was reported by 23 out of 25 (92%) of participants, being by far the most frequent symptom. It was the sole manifestation in nearly one third of the patients (8/25, 32.0%). Headache was typically severe (19/23, 82.6%) and throbbing (16/23, 69.5%), with sudden onset (13/23, 56.5%) and non-remitting (20/23, 86.9%) characteristics. The sinus most frequently involved was the transverse sinus (24/25, 96.0%), either alone or in association with other sinuses. Headache is the most frequent symptom and sometimes the sole presentation of CVT. © 2015 American Headache Society.

    Purpose Video games provide a promising platform for rehabilitation of speech disorders. Although video games have been used to train speech perception in foreign language learners and have been proposed for aural rehabilitation, their use in speech therapy has been limited thus far. We present feasibility results from at-home use in a case series of children with velopharyngeal dysfunction (VPD) using an interactive video game that provided real-time biofeedback to facilitate appropriate nasalization. Method Five participants were recruited across a range of ages, VPD severities, and VPD etiologies. Participants completed multiple weeks of individual game play with a video game that provides feedback on nasalization measured via nasal accelerometry. Nasalization was assessed before and after training by using nasometry, aerodynamic measures, and expert perceptual judgments. Results Four participants used the game at home or school, with the remaining participant unwilling to have the nasal accelerometer secured to his nasal skin, perhaps due to his young age. The remaining participants showed a tendency toward decreased nasalization after training, particularly for the words explicitly trained in the video game. Conclusion Results suggest that video game–based systems may provide a useful rehabilitation platform for providing real-time feedback of speech nasalization in VPD.

    Idiopathic spinal cord herniation (ISCH) is an uncommon condition located predominantly in the thoracic spine and often associated with a remote history of a major traumatic injury. ISCH has an incompletely described presentation and unknown etiology. There is no consensus on the treatment algorithm and surgical technique, and there are few data on clinical outcomes. In this case series and technical report, we describe the atypical myelopathy presentation, remote history of traumatic injury, radiographic progression, treatment, and outcomes of 5 patients treated at Washington University for symptomatic ISCH. A video showing surgical repair is presented. In contrast to classic compressive myelopathy symptomatology, ISCH patients presented with an atypical myelopathy, characterized by asymmetric motor and sensory deficits and early-onset urinary incontinence. Clinical deterioration correlated with progressive spinal cord displacement and herniation observed on yearly spinal imaging in a patient imaged serially because of multiple sclerosis. Finally, compared with compressive myelopathy in the thoracic spine, surgical treatment of ISCH led to rapid improvement despite a long duration of symptoms. Symptomatic ISCH presents with atypical myelopathy and slow temporal progression and can be successfully managed with surgical repair.

    For the growing numbers of obese elderly with diabetes, the glucagon-like peptide-1 (GLP-1) receptor analogue (liraglutide) appears a safe way to promote and maintain substantial weight loss. Given this background, the aim of this study was to assess the effect of the liraglutide treatment, at doses up to 3.0 mg per day, on the body composition, focusing on sarcopenia, in overweight and obese elderly with type 2 diabetes mellitus (T2DM). A perspective study was carried out in overweight and obese T2DM patients with HbA1c equal to 7.0 % (53 mmol/mol) ~10.0 % (86), under 3-month treatment (at least) of maximal dose of metformin at stable regime, and additional liraglutide at doses up to 3.0 mg per day. Body composition markers such as skeletal muscle index (SMI), android and gynoid fat mass, and arms and legs fat free mass, was measured by dual-energy X-ray densitometry (DXA) at baseline and after 24 weeks of liraglutide treatment. Glucose control was also carried out by glucose and HbA1c. Nine subjects (male/female 6/3, mean age 68.22 ± 3.86 years, BMI 32.34 ± 4.89 kg/m 2 ) were evaluated. We noted a median decrease in BMI (-0.78 kg/m 2 ), weight (-2000 g), fat mass (-1498 g) and android fat (-0.9 %), and a increase in SMI (+0.03 kg/m 2 ) from baseline. Glycemic control also improved, with a median change HbA1c of -0.80 %. Twenty-four weeks of liraglutide treatment was associated with reductions in fat mass and android fat. In addition, in order to prevent sarcopenia, it preserved the muscular tropism.

    Full Text Available Abstract Background Coeliac disease in adolescents has been associated with an increased prevalence of depressive and disruptive behavioural disorders, particularly in the phase before diet treatment. We studied the possible effects of a gluten-free diet on psychiatric symptoms, on hormonal status (prolactin, thyroidal function and on large neutral amino acid serum concentrations in adolescents with coeliac disease commencing a gluten-free diet. Methods Nine adolescents with celiac disease, aged 12 to 16 years, were assessed using the semi-structured K-SADS-Present and Lifetime Diagnostic interview and several symptom scales. Seven of them were followed at 1 to 2, 3, and 6 months on a gluten-free diet. Results Adolescent coeliac disease patients with depression had significantly lower pre-diet tryptophan/ competing amino-acid (CAA ratios and free tryptophan concentrations, and significantly higher biopsy morning prolactin levels compared to those without depression. A significant decrease in psychiatric symptoms was found at 3 months on a gluten-free diet compared to patients' baseline condition, coinciding with significantly decreased coeliac disease activity and prolactin levels and with a significant increase in serum concentrations of CAAs. Conclusion Although our results of the amino acid analysis and prolactin levels in adolescents are only preliminary, they give support to previous findings on patients with coeliac disease, suggesting that serotonergic dysfunction due to impaired availability of tryptophan may play a role in vulnerability to depressive and behavioural disorders also among adolescents with untreated coeliac disease.

    Although Ki67 index suffers from poor reproducibility, it is one of the most important prognostic markers used by oncologists to select the treatment of estrogen receptor (ER) positive breast cancer patients. In this study, we aim to establish the optimal Ki67 cut-offs for stratifying patient prognosis and to create a comprehensive prognostic index for clinical applications. A mono-institutional cohort of 1.577 human epidermal growth factor receptor 2 negative/ER+ breast cancer patients having complete clinical, histological, and follow-up data was collected. The 14 and 20 % Ki67 cut-offs were correlated to disease-free interval (DFI) and disease-specific survival (DSS). To create a comprehensive prognostic index, we used independent variables selected by uni/multivariate analyses. In terms of DFI and DSS, patients bearing tumors with Ki67 Ki67 values between 14 and 20 %. Patients with tumor with Ki67 > 20 % showed the poorest prognosis. Moreover, to tumor size, the number of metastatic lymph nodes and Ki67 > 20 % was given a score value, varying depending on definite cut-offs and used to create a prognostic index, which was applied to the population. Patients with a prognostic index ≥3 were characterized by significant risk of relapse [DFI: Hazard Ratio (HR) = 4.74, p Ki67 cut-off is the best to stratify high-risk patients in luminal breast cancers, and we suggest to integrate it with other prognostic factors, to better stratify patients at risk of adverse outcome.

    Full Text Available Retinoblastoma is the most common primary malignant intra-ocular tumor in children. Although intra-arterial chemotherapy (IAC by selectively infusing chemotherapy through the ophthalmic artery has become an essential technique in the treatment of advanced intra-ocular retinoblastoma in children, the outcome of IAC as primary therapy for infants less than 3 months of age remains unknown. In this retrospective study, we reviewed the outcome of IAC as primary therapy for retinoblastoma in infants less than 3 months of age.We retrospectively reviewed ten retinoblastoma patients attending our center from January 2009 to September 2015 and beginning primary IAC before the age of 3 months. The patient characteristics, overall outcomes and therapy-related complications were assessed.The mean patient age at the first IAC treatment was 10.4 weeks (range 4.9-12.9 weeks. These eyes were classified according to the International Classification of Retinoblastoma (ICRB as group A (n = 0, B (n = 2, C (n = 0, D (n = 9, or E (n = 2. A total of 28 catheterizations were performed, and the procedure was stopped in one patient because of internal carotid artery spasm. Each eye received a mean of 2.6 cycles of IAC (range 2-4 cycles. After IAC with a mean follow-up of 28.3 months (range 9-65 months, tumor regression was observed in 12 of 13 eyes. One eye was enucleated due to tumor progression. All patients are alive and no patient has developed metastatic disease or other malignancies.Our experience suggests IAC as primary therapy is a feasible and promising treatment for retinoblastoma in infants less than 3 months of age.

    Adnexal tumors of the skin are a large and diverse group of benign and malignant neoplasms, which exhibit morphological differentiation toward one of the different types of adnexal epithelium present in normal skin and they pose a diagnostic challenge. The purpose of this study is to share our experience with these rare but aggressive tumors at a tertiary care cancer hospital in a developing country. A retrospective review of 11 patients diagnosed with rare adnexal tumors and their variants from January 2005 to December 2014, treated either surgically or non-surgically, was performed to describe the clinicopathological characteristics and outcome of the disease. A total of 11 patients were diagnosed with adnexal carcinoma and its variants: a 34-year-old Sindhi man, a 59-year-old Punjabi woman, a 32-year-old woman from Khyber Pakhtunkhwa, a 43-year-old Punjabi woman, a 64-year-old Punjabi man, a 51-year-old man from Khyber Pakhtunkhwa, a 51-year-old Punjabi woman, a 74-year-old Punjabi woman, a 75-year-old Punjabi man, a 61-year-old man from Khyber Pakhtunkhwa, and a 53-year-old man from Khyber Pakhtunkhwa. The male to female ratio was 1.2:1. The histological variations were sebaceous differentiation (n = 4), microcystic adnexal carcinoma (n = 4), trichilemmal carcinoma (n = 1), pilomatrix carcinoma (n = 1), and hidradenocarcinoma (n = 1). The mean age at presentation was 54 years (range 32 to 75). The primary subsite of involvement was the scalp in nine patients followed by eyelids in two patients. Surgery was the primary treatment modality in almost all patients; postoperative radiotherapy (PORT) was offered to eight patients. The median dose of radiation was 45 Gy to the primary site. Indications for radiotherapy included close margins (n = 2), positive margins (n = 1), high grade histology (n = 4), and multifocal disease (n = 1). On follow-up, two patients presented with local, one regional and two patients developed distant metastasis. Adnexal carcinomas are

    Acute appendicitis is one of the most common acute surgical pathology we encountered. In this study we investigated our pregnant cases of appendicitis, and reviewed literature. A total of 21 pregnant women who underwent appendectomy with the initial diagnosis of acute appendicitis in Istanbul Medeniyet University Clinics of General Surgery between January 2012, and December 2014 were retrospectively analyzed. The patients's ages, trimesters, complaints, abdominal examination, laboratory, and ultrasonographic findings, surgical techniques, complications and hospital stay were noted. The patients were in their first (n=12; 57.1%), second (n=5; 23.8%), and third trimesters (n=4; 19.0%) of their pregnancies Median age was 23.9 years. All of the patients had abdominal pain. Median value of WBC count was 13.297/mm³. Ultrasound was positive in 12 patients (57.1%). In 14 (66.6%) patients McBurney incision, and in 6 (28.6%) cases right paramedian incision were used. One patient (4.8%) underwent laparoscopic appendectomy. Nineteen cases were acute appendicitis (90.5%), and two cases were perforated appendicitis (9.5%). Average hospital stay was 3.8 days. Two cases with perforated acute appendicitis developed wound infection and treated conservatively. There were no fetomaternal mortality. Physiologically anatomic and biochemical changes occurring during pregnancy can delay the diagnosis of acute appendicitis threaten the lives of both the mother and the fetus Therefore, rapid diagnosis and appropriate treatment convey importance.

    Integrated community case management (iCCM) relies on community health workers (CHWs) managing children with malaria, pneumonia, diarrhoea, and referring children when management is not possible. This study sought to establish the cost per sick child referred to seek care from a higher-level health facility by a CHW and to estimate caregivers' willingness to pay (WTP) for referral. Caregivers of 203 randomly selected children referred to higher-level health facilities by CHWs were interviewed in four Midwestern Uganda districts. Questionnaires and document reviews were used to capture direct, indirect and opportunity costs incurred by caregivers, CHWs and health facilities managing referred children. WTP for referral was assessed through the 'bidding game' approach followed by an open-ended question on maximum WTP. Descriptive analysis was conducted for factors associated with referral completion and WTP using logistic and linear regression methods, respectively. The cost per case referred to higher-level health facilities was computed from a societal perspective. Reasons for referral included having fever with a negative malaria test (46.8%), danger signs (29.6%) and drug shortage (37.4%). Among the referred, less than half completed referral (45.8%). Referral completion was 2.8 times higher among children with danger signs (p = 0.004) relative to those without danger signs, and 0.27 times lower among children who received pre-referral treatment (p average cost per case referred was US$ 4.89 and US$7.35 per case completing referral. For each unit cost per case referred, caregiver out of pocket expenditure contributed 33.7%, caregivers' and CHWs' opportunity costs contributed 29.2% and 5.1% respectively and health facility costs contributed 39.6%. The mean (SD) out of pocket expenditure was US$1.65 (3.25). The mean WTP for referral was US$8.25 (14.70) and was positively associated with having received pre-referral treatment, completing referral and increasing

    Recent studies have shown the potential of Synthetic Aperture Radars (SAR) for mapping of rice fields and some other vegetation types. For rice field classification, conventional classification techniques have been mostly used including manual threshold-based and supervised classification approaches. The challenge of the threshold-based approach is to find acceptable thresholds to be used for each individual SAR scene. Furthermore, the influence of local incidence angle on backscatter hinders using a single threshold for the entire scene. Similarly, the supervised classification approach requires different training samples for different output classes. In case of rice crop, supervised classification using temporal data requires different training datasets to perform classification procedure which might lead to inconsistent mapping results. In this study we present an automatic method to identify rice crop areas by extracting phonological parameters after performing an empirical regression-based normalization of the backscatter to a reference incidence angle. The method is evaluated in the Red River Delta (RRD), Vietnam using the time series of ENVISAT Advanced SAR (ASAR) Wide Swath (WS) mode data. The results of rice mapping algorithm compared to the reference data indicate the Completeness (User accuracy), Correctness (Producer accuracy) and Quality (Overall accuracies) of 88.8%, 92.5 % and 83.9 % respectively. The total area of the classified rice fields corresponds to the total rice cultivation areas given by the official statistics in Vietnam (R2  0.96). The results indicates that applying a phenology-based classification approach using backscatter time series in optimal incidence angle normalization can achieve high classification accuracies. In addition, the method is not only useful for large scale early mapping of rice fields in the Red River Delta using the current and future C-band Sentinal-1A&B backscatter data but also might be applied for other rice

    Full Text Available Introduction: Transverse facial cleft (Tessier type 7 or congenital macrostomia is a rare congenital anomaly seldom occurring alone and is frequently associated with deformities of the structures developing from the first and second branchial arches. The reported incidence of No. 7 cleft varies from 1 in 60,000 to 1 in 300,000 live births. Material and Methods: Seventeen patients of transeverse facial cleft who presented to us in last 5 years were included in the study. Their history regarding familial and environmental predispositions was recorded. The cases were analysed on basis of sex, laterality, severity, associated anomalies and were graded according to severity. They were operated by z plasty technique and were followed up for 2 years to look for effectiveness of the technique and its complications. Result: Out of the seventeen patients of transverse cleft, none had familial predilection or any environmental etiology like antenatal radiological exposure or intake of drugs of teratogenic potential. Most of the patients (9/17 were associated with hemifacial microsomia and 1 patient was associated with Treacher Colin′s Syndrome. Out of the 6 cases of Grade I clefts, 4 were isolated transverse clefts and of the 10 patients of Grade II clefts, 7 were associated with hemifacial microsomia. We encountered only one case of Grade III Transverse Cleft which was not only associated with hemifacial microsomia but also had cardiac anomaly. Out of the17 cases, 15 were operated and in most of them the outcome was satisfactory.

    Leptospirosis belongs to the spectrum of travel-related infections. We retrospectively studied all the consecutive cases of travel-related leptospirosis seen in our department between January 2008 and September 2011. Patients were included with a clinical picture compatible with the disease within 21 days after return, the presence of a thermoresistant antigen or IgM antibodies, Elisa ≥ 1 /400, and a positive microagglutination test (MAT) ≥ 1/100. Fifteen leptospirosis cases were evaluated. Exposure occurred in Asia (47%), Africa (20%), the Caribbean (20%), and Indian Ocean (13%). Fourteen patients were infected during water-related activities. On admission the most frequent symptoms were fever (100%), headache (80%), and digestive disorders (67%). Relevant laboratory findings included impaired liver function tests (100%), lymphocytopenia (80%), thrombocytopenia (67%), and elevated C-reactive protein (CRP) (67%). Our cases were confirmed by MAT that found antibodies against nine different serovars. Seven patients were cured with amoxicillin, four with doxycycline, two with ceftriaxone, one with ceftriaxone, doxycycline, and spiramycin, whereas one recovered spontaneously (retrospective diagnosis). Eight patients were hospitalized. All patients recovered. Our cases involved nine different serovars. They were related to travel in Asia, Africa, and the Caribbean. Bathing or other fresh-water leisure activities (canoeing, kayaking, rafting) are the most likely at-risk exposure. Any traveler with fever and at-risk exposure should be investigated for leptospirosis. © 2013 International Society of Travel Medicine.

    A case series of consecutive patients with cervical radiculopathy. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy. However, outcome studies using consistent treatment approaches on a well-defined sample of patients are lacking. The purpose of this case series is to describe the outcomes of a consecutive series of patients presenting to physical therapy with cervical radiculopathy and managed with the use of manual physical therapy, cervical traction, and strengthening exercises. Eleven consecutive patients (mean age, 51.7 years; SD, 8.2) who presented with cervical radiculopathy on the initial examination were treated with a standardized approach, including manual physical therapy, cervical traction, and strengthening exercises of the deep neck flexors and scapulothoracic muscles. At the initial evaluation all patients completed self-report measures of pain and function, including a numeric pain rating scale (NPRS), the Neck Disability Index (NDI), and the Patient-Specific Functional Scale (PSFS). All patients again completed the outcome measures, in addition to the global rating of change (GROC), at the time of discharge from therapy and at a 6-month follow-up session Ten of the 11 patients (91%) demonstrated a clinically meaningful improvement in pain and function following a mean of 7.1 (SD, 1.5) physical therapy visits and at the 6-month follow-up. Ninety-one percent (10 of 11) of patients with cervical radiculopathy in this case series improved, as defined by the patients classifying their level of improvement as at least "quite a bit better" on the GROC. However, because a cause-and-effect relationship cannot be inferred from a case series, follow-up randomized clinical trials should be performed to further investigate the effectiveness of manual physical therapy, cervical traction, and strengthening exercises in a homogeneous group of patients with cervical radiculopathy.

    Cleft lip and/or palate (CL/P) represent the most common congenital anomalies of the face, corresponding to approximately 65% of all malformations of the craniofacial region. to describe unusual clinical cases of non-syndromic CL/P (CL/PNS), diagnosed in a reference service in Minas Gerais, Brazil, and correlate these alterations with possible risk factors. we carried out a retrospective study, between the years of 1992 and the 1st half of 2009, from medical records. Among the 778 cases of CL/PNS diagnosed in the period of 17 years, 5 (0.64%) were unusual CL/PNS, and all patients were male. It was found that among the 5 patients, 2 had incomplete right cleft lip with incomplete cleft palate, 2 were affected by left incomplete cleft lip and incomplete cleft palate, and 1 had a cleft lip and palate associated with complete right cleft palate. Risk factors such as consanguinity, maternal smoking and alcohol consumption, medication usage during pregnancy, history of abortion and/or stillbirths and maternal diseases were not associated with unusual CL/PNS. This study described 5 unusual cases of CL/PNS in a Brazilian population; no associations with the risk factors analyzed were seen. It also confirmed the unusualness of the prevalence of such alterations.

    Eosinophilic inflammation may occur in any part of the intestinal tract from the esophagus to the rectum. Despite 70 yr having passed since the first reference to a case of eosinophilic gastroenteritis, the epidemiology and natural history of eosinophilic gastrointestinal disorders are still poorly known. Insights into their etiology and pathogenesis have revealed an important role for allergens; interleukins 4, 5, and 13; the eotaxin family of chemokines; and eosinophil-derived proteins. Diagnosis is confirmed by typical histologic features in a patient with a suggestive clinical phenotype. Treatment involves eliminating triggering allergens, making dietary restrictions the first choice of therapy in a compliant patient; corticosteroids [topical in eosinophilic esophagitis (EE)], despite the potential for serious side effects, are used with success in refractory and non-compliant patients. In this study we discuss EE and gastroduodenitis against the backdrop of clinical case presentations.

    Full Text Available INTRODUCTION: Paracoccidioidomycosis (PCM is the most important systemic mycosis in South America. Central nervous system involvement is potentially fatal and can occur in 12.5% of cases. This paper aims to contribute to the literature describing eight cases of neuroparacoccidioidomycosis (NPMC and compare their characteristics with patients without neurological involvement, to identify unique characteristics of NPCM. METHODS: A cohort of 213 PCM cases was evaluated at the Infectious Diseases Clinic of the University Hospital, Federal University of Minas Gerais, Brazil, from October 1976 to August 2008. Epidemiological, clinical, laboratory, therapeutic and follow-up data were registered. RESULTS: Eight patients presented NPCM. The observed NPCM prevalence was 3.8%. One patient presented the subacute form of PCM and the other seven presented the chronic form of the disease. The parenchymatous form of NPCM occurred in all patients. 60% of the patients who proceeded from the north/ northeast region of Minas Gerais State developed NPCM. The neurological involvement of a mother and her son was observed. NPCM patients exhibited demographical and clinical profiles similar to what is described in the literature. When NPCM cases were compared to PCM patients, there were differences in relation to origin and positive PCM family history. CONCLUSIONS: The results corroborate the clinical view that the neurological findings are extremely important in the evaluation of PCM patients. Despite the limitations of this study, the differences in relation to patient's origins and family history point to the need of further studies to determine the susceptibility factors involved in the neurological compromise.

    The use of left ventricular assist devices (LVADs) has become a state-of-the-art therapy for advanced cardiac heart failure; however, multiple reports in the literature describe an increased risk for gastrointestinal (GI) bleeding in these patients. We characterized this association by reviewing recent studies on this topic. GI bleeding occurs frequently in patients with LVADs, especially with devices with nonpulsatile flow patterns. We performed a comprehensive literature review to identify articles that reported GI bleeding in patients with LVADs. Databases used included PubMed, EMBASE, Scopus, Web of Knowledge, and Ovid. Baseline and outcome data were then ed from these reports. We identified 10 case reports and 22 case series with 1543 patients. The mean age was 54.2 years. Most patients had nonpulsatile LVADs (1316, 85.3%). Three hundred and seventeen patients (20.5%) developed GI bleeding; this occurred more frequently in patients with nonpulsatile LVADs. Multiple procedures were performed without complications but often did not identify a definite bleeding site. Suspect lesions occurred throughout the GI tract but were more frequent in the upper GI tract. Many patients had arteriovenous malformations. All patients received medical therapy. None of the patients had their LVAD replaced. The use of anticoagulation did not appear to predispose these patients to more GI bleeding episodes. Patients with LVADs have frequent GI bleeds, especially from arteriovenous malformations, which can occur throughout the GI tract. Most diagnostic and therapeutic interventions can be used safely in these patients. The pathogenesis of the GI bleeding in these patients may involve the use of anticoagulant medications, the formation of arteriovenous malformations, loss of von Willebrand factor activity, and mucosal ischemia. © 2013 Wiley Periodicals, Inc.

    Full Text Available Introduction: Gout is an increasingly common medical problem. The traditional risk factors of male sex and high red meat or alcohol consumption have been joined with newer risks such as increased life expectancy, and the metabolic syndrome (hypertension, diabetes, dyslipidaemia, truncal obesity. Methods: This was a retrospective study to determine the epidemiology, clinical features, associated conditions as well as renal related conditions in existing gout patients followed-up in Rheumatology outpatient clinic, Hospital Tuanku Ja’afar, Seremban. Results: Over a three month period, we identified 54 gouty patients on our follow-up, the majority being male, Malay ethnicity, withthe age of onset in the third and fourth decades of life. Commonly associated risk factors were hypertension, hyperlipidaemia and obesity. However, underlying history of diabetes mellitus, alcohol consumption, and family history were not commonly associated with gout in our group of patients. Half of our patients had at least two or more joints involvement. About half of the patients with tophaceous gout had renal impairment. Conclusion: Our series of gout patients highlight the high prevalence of cardiovascular risk factors. The high prevalence of tophi and renal impairment is a cause for concern.

    Branding refers to a process whereby third degree burns are inflicted on the skin with a hot iron rod or metallic object. Branding employs the phenomenon of "counter irritation," and is widely used by faith healers in developing countries for therapeutic purposes. Some methods, which are very crude and inhuman, carry a large risk of complications. The purpose of this study is to present a series of complications and to familiarize clinicians with this dangerous method of treatment. Four Pakistani patients, three male and one female, ranging from 25 to 60 years of age "branded" with a red hot iron rod for various medical reasons presented with severe medical complications to our tertiary care hospital. The mean duration between the procedure and presentation to the hospital was 6 days. At the time of admission, two patients had septic shock, one patient had cavernous sinus thrombosis and one patient had multiple splenic abscesses. All patients received standard care for wound management and systemic infections. Two patients eventually died during the course of treatment. Severe complications from branding are troublesome and the potential risks of this treatment outweigh its benefits. Globally, there is a great need for heightened awareness about the dangers of branding among patients and physicians, as this will have an important effect on patients who seek branding for various medical conditions.

    An autoimmune disease is characterized by tissue damage, caused by self-reactivity of different effector mechanisms of the immune system, namely antibodies and T cells. All autoimmune diseases, to some extent, have implications for fertility and obstetrics. Currently, due to available treatments and specialised care for pregnant women with autoimmune disease, the prognosis for both mother and child has improved significantly. However these pregnancies are always high risk. The purpose of this study is to analyse the fertility/pregnancy process of women with systemic and organ-specific autoimmune diseases and assess pathological and treatment implications. The authors performed an analysis of the clinical records and relevant obstetric history of five patients representing five distinct autoimmune pathological scenarios, selected from Autoimmune Disease Consultation at the Hospital of Braga, and reviewed the literature. The five clinical cases are the following: Case 1-28 years old with systemic lupus erythematosus, and clinical remission of the disease, under medication with hydroxychloroquine, prednisolone and acetylsalicylic acid, with incomplete miscarriage at 7 weeks of gestation without signs of thrombosis. Case 2-44 years old with history of two late miscarriages, a single preterm delivery (33 weeks) and multiple thrombotic events over the years, was diagnosed with antiphospholipid syndrome after acute myocardial infarction. Case 3-31 years old with polymyositis, treated with azathioprine for 3 years with complete remission of the disease, took the informed decision to get pregnant after medical consultation and full weaning from azathioprine, and gave birth to a healthy term new-born. Case 4-38 years old pregnant woman developed Behcet's syndrome during the final 15 weeks of gestation and with disease exacerbation after delivery. Case 5-36 years old with autoimmune thyroiditis diagnosed during her first pregnancy, with difficult control over the thyroid

    Homicide-suicide is a rare event, but it has a significant impact on the family and community of the perpetrator and victim(s). The phenomenon of late-life homicide-suicide has not been previously studied in New Zealand, and there is only limited data in the international literature. The aim of this study is to systematically review coroners' records of late-life homicide-suicides in New Zealand. After ethics approval was granted, the Coronial Services of New Zealand was approached to provide records of all closed cases with a suicide verdict (age 65+) over a five-year period (July 2007-December 2012). Of the 225 suicides, 4 cases of homicide-suicide were identified (an estimated incidence of 0.12 per 100,000 per persons year). All four perpetrators were men; three had been farmers. Their ages ranged from 65 to 82. One case occurred in the context of an underlying psychiatric illness (psychotic depression in bipolar disorder). Firearms were used in three cases. Two cases were categorized as spousal/consortial subtype, one case as filicide-suicide, and one case as siblicide-suicide. The prospect of major social upheaval in the form of losing their homes was present in all four cases. The findings of this case series were consistent with the limited existing literature on homicide-suicide. Age-related biopsychosocial issues were highlighted in this case series of late-life homicide-suicide. Additionally, evaluating firearm licences in high-risk groups may represent a prevention strategy. © 2015 The Authors. Psychogeriatrics © 2015 Japanese Psychogeriatric Society.

    Full Text Available Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL; postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes; no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1, 41–60 (n=1, and >60 (n=55; scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

    Full Text Available Background: Cerebral venous sinus thrombosis (CVST is a rare form of stroke seen in young and middle aged group, especially in women due to thrombus of dural venous sinuses and can cause acute neurological deterioration with increased morbidity and mortality if not diagnosed in early stage. Neurological deficit occurs due to focal or diffuse cerebral edema and venous non-hemorrhagic or hemorrhagic infarct. Aim and Objectives: To assess/evaluate the role of Magnetic Resonance Imaging (MRI and Magnetic Resonance Venography (MRV as an imaging modality for early diagnosis of CVST and to study patterns of venous thrombosis, in detecting changes in brain parenchyma and residual effects of CVST using MRI. Materials and Methods: Retrospective descriptive analysis of 40 patients of CVST diagnosed on MRI brain and MRV was done. Results: 29/40 (72.5% were males and 11/40 (27.5% were females. Most of the patients were in the age group of 21-40 years (23/40-57.5%. Most of the patients 16/40 (40% presented within 7 days. No definite cause of CVST was found in 24 (60% patients in spite of detailed history. In 36/40 (90% of cases major sinuses were involved, deep venous system were involved in 7/40 (17.5% cases, superficial cortical vein was involved in 1/40 (2.5% cases. Analysis of stage of thrombus (acute, subacute, chronic was done based on its appearance on T1 and T2WI. 31/40 (77.5% patients showed complete absence of flow on MRV, while 9/40 (22.5% cases showed partial flow on MR venogram. Brain parenchyma was normal in 20/40 (50% patients while 6/40 (15% cases had non-hemorrhagic infarct and 14/40 (35% patients presented with hemorrhagic infarct. Conclusion: Our study concluded that MRI brain with MRV is sensitive in diagnosing both direct signs (evidence of thrombus inside the affected veins and indirect signs (parenchymal changes of CVST and their follow up.

    Full Text Available Maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. The majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. Conventional radiographs could not differentiate between inflammatory mucosal thickening, neoplasm, and hypoplasia of the sinus. Computed tomography (CT and also cone beam computed tomography (CBCT are the proper modalities to detect these conditions. In the present study, CBCT findings of three cases with maxillary sinus hypoplasia and aplasia are reported.

    Imatinib showed activity in 50 chordoma patients treated within a Phase II study. In that study, 70% of patients remained with stable disease (SD), median progression free survival (PFS) was 9 months and median overall survival (OS) was 34 months. We now report on a retrospective series of PDGFB/PDGFRB positive advanced chordoma patients treated with imatinib as a single agent within a compassionate-use programme at Istituto Nazionale Tumori, Milan, Italy (INT) between August 2002 and November 2010, when the programme was closed. 48 patients were consecutively treated with imatinib 800 mg/d. All patients had inoperable and progressive disease before starting imatinib. Demographics, treatment duration, toxicity and response rate by Response Evaluation Criteria in Solid Tumors (RECIST) were retrospectively recorded. The median duration of therapy was 7 months (1-46.5). No patient is on therapy at present. 46 patients were evaluable for response. No partial responses were detected. Best response was: stable disease 34 (74%), progressive disease 12 (26%). At a median follow-up of 24.5 months (0.5-117), median PFS was 9.9 months (95% confidence interval (CI) 6.7-13). Eight patients (16.5%) remained on therapy >18 months and 10 patients (21%) remained progression-free >18 months. Median OS was 30 months (95% CI 20-40), with 24 (50%) patients dead at the time of the present analysis. We confirm the activity of imatinib in locally advanced and metastatic chordoma, in terms of >70% tumour growth arrest in previously progressive patients. Median duration of response lasted almost 10 months, with >20% of patients progression-free at 18+ months. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Creutzfeldt-Jakob disease is a rare and fatal neurodegenerative disorder that affects mammals and humans. The prevalence of this disease in the United States is 0.5 to 1 per million inhabitants. So far in Ecuador, we do not know what the prevalence or incidence is, and only one case report has been written. We present a case series of Creutzfeldt-Jakob disease in a third-level hospital in Quito. The average age of symptom onset in our patients was 58.8 years. The male to female ratio was 1:1. Two patients began with cognitive/behavioral symptoms, while 4 patients began with focal neurological signs; 1 case with ataxia, 2 with gait disorders and 1 with vertigo and headache. All of the patients had the clinical features established by the World Health Organization. In addition, the entire cohort was positive for the 14-3-3 protein in cerebrospinal fluid, and had high signal abnormalities in caudate and putamen nucleus in DWI and FLAIR IRM. Only in one case, did we reach a definitive diagnosis through a pathological study. All other cases had a probable diagnosis. In this series of cases, 6 out of 6 patients died. The average time from the onset of the symptoms to death in this cohort was 13 months. This is the first report of a series of cases of Creutzfeldt-Jakob disease in Quito. Although definitive diagnosis must be histopathological, there are ancillary tests currently available that have allowed us to obtain a diagnosis of the disease.

    The clinical presentation of congenital portosystemic shunt is variable and gastrointestinal bleeding is an uncommon presentation. To describe the imaging features of congenital portosystemic shunt as it presented in 11 children with (n = 6) and without gastrointestinal bleeding (n = 5). We performed a retrospective study on a clinical and imaging dataset of 11 children diagnosed with congenital portosystemic shunt. A total of 11 children with congenital portosystemic shunt were included in this study, 7 with extrahepatic portosystemic shunts and 4 with intrahepatic portosystemic shunts. Six patients with gastrointestinal bleeding had an extrahepatic portosystemic shunt, and the imaging results showed that the shunts originated from the splenomesenteric junction (n = 5) or splenic vein (n = 1) and connected to the internal iliac vein. Among the five cases of congenital portosystemic shunt without gastrointestinal bleeding, one case was an extrahepatic portosystemic shunt and the other four were intrahepatic portosystemic shunts. Most congenital portosystemic shunt patients with gastrointestinal bleeding had a shunt that drained portal blood into the iliac vein via an inferior mesenteric vein. This type of shunt was uncommon, but the concomitant rate of gastrointestinal bleeding with this type of shunt was high. (orig.)

    The aim of this study was to describe clinical features unique to supratrochlear neuralgia. The supratrochlear nerve supplies the medial aspect of the forehead. Due to the intricate relationship between supraorbital and supratrochlear nerves, neuralgic pain in this region has been traditionally attributed to supraorbital neuralgia. No cases of supratrochlear neuralgia have been reported so far. From 2009 through 2016, we prospectively recruited patients with pain confined to the territory of the supratrochlear nerve. Fifteen patients (13 women, 2 men; mean age 51.4 years, standard deviation 14.9) presented with pain in the lower paramedian forehead, extending to the eyebrow in two patients and to the internal angle of the orbit in another. Pain was unilateral in 11 patients (six on the right, five on the left), and bilateral in four. Six patients had continuous pain and nine described intermittent pain. Palpation of the supratrochlear nerve at the medial third of the supraorbital rim resulted in hypersensitivity in all cases. All but one patient exhibited sensory disturbances within the painful area. Fourteen patients underwent anesthetic blockades of the supratrochlear nerve, with immediate relief in all cases and long-term remission in three. Six of them had received unsuccessful anesthetic blocks of the supraorbital nerve. Five patients were treated successfully with oral drugs and one patient was treated with radiofrequency. Supratrochlear neuralgia is an uncommon disorder causing pain in the medial region of the forehead. It may be differentiated from supraorbital neuralgia and other similar headaches and neuralgias based on the topography of the pain and the response to anesthetic blockade. © 2017 American Headache Society.

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

    Small bowel diverticulosis of the jejunum and ileum is an uncommon finding with a prevalence rate of 0.2% to 1.3% at autopsy and 0.3% to 1.9% on small bowel studies. Diagnosis can be difficult because there are no pathognomonic features or clinical symptoms that are specific for small bowel diverticulosis. Though rare, it is critical to keep the possibility of small bowel diverticulosis in mind when evaluating cases of malabsorption, chronic abdominal pain, haemorrhage, perforation and intestinal obstruction, especially in patients with connective tissue disorders, a family history of diverticula and a personal history of colonic diverticulosis. Guidelines for the treatment of complicated small bowel diverticulosis are not clearly defined. However, the consensus in treatment is to do a small bowel resection with primary anastomosis. We report three interesting cases of jejunoileal diverticula that presented in an occult manner and later progressed to more emergent manifestations. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Omental infarction is a rare disease entity that can cause acute or subacute abdominal pain. In the past, it was thought that omental infarction mainly occurred on the right side because it was detected when surgery was performed on patients who complained of abdominal pain on the right side. We present this case to demonstrate that omental infarction can occur at any site, including the epigastric area and the lower abdomen, and even on the left side where the greater omentum is located. Four patients with omental infarction presented to the Emergency Department with various clinical symptoms. All of them were diagnosed by computed tomography scan. Omental infarction occurred on the right side in 2 patients, at the epigastric area in 1 patient, and on the left side in 1 patient. Three were improved with supportive care. Laparoscopy was performed in 1 patient because his abdominal pain persisted despite conservative treatment. Omental infarction should be included in the differential diagnosis list of acute abdominal pain because it can occur at any site. In addition, because this disease runs a self-limited course, conservative care is recommended. Thus, unnecessary operations can be avoided in cases where omental infarction is diagnosed by imaging studies. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Objective:To describe the clinical and laboratory presentation of hemophagocytic lymphohistiocytosis in children treated at a referral institution.Methods:A retrospective descriptive study was carried out of seven children diagnosed with hemophagocytic lymphohistiocytosis between 2010 and 2012. The criteria for diagnosis were those proposed by the Histiocyte Society. When indicated, immunochemotherapy was prescribed according to the HLH94 and HLH2004 protocols of the Histiocyte Society.Results:The patients' ages at diagnosis ranged from one month to nine years. All patients had splenomegaly, fever, anemia, thrombocytopenia, hyperferritinemia and hypertriglyceridemia. Bone marrow hemophagocytosis was detected in six patients. In six cases, infectious diseases triggered the syndrome. In two cases, associated with visceral leishmaniasis, remission was achieved after treatment of the underlying infection. Three patients, who had Epstein–Barr-related hemophagocytic lymphohistiocytosis, required treatment with immunochemotherapy. They are alive and in remission; one patient had symptoms of juvenile rheumatoid arthritis and another, who was suspected of having primary hemophagocytic lymphohistiocytosis, entered into remission after bone marrow transplantation. Two deaths (28.6% occurred in patients with suspected primary hemophagocytic lymphohistiocytosis; one whose clinical picture was triggered by cytomegalovirus infection did not respond to immunochemotherapy and the other died before any specific treatment was provided.Conclusion:As reported before, hemophagocytic lymphohistiocytosis has a multifaceted presentation with nonspecific signs and symptoms. In secondary forms, remission may be achieved by treating the underlying disease. In the primary forms, remission may be achieved with immunochemotherapy, but bone marrow transplantation is required for cure.

    Full Text Available Background: Ovarian cancer is the 4th commonest cancer among Egyptian women. It can spread through 3 different lymphatic pathways to para-aortic/paracaval lymph nodes, to pelvic lymph nodes and only occasionally through the round ligament of the uterus to the inguinal nodes. These rare cases are staged IVb on FIGO system. Presentation: We present a series of 4 cases of ovarian cancer metastasizing to inguinal nodes. The literature review revealed only 17 published similar cases. Management controversies as well as prognosis are discussed in our study. Conclusion: Inguinal metastasis from ovarian cancer seems more frequent than previously thought. Examination of inguinal region should be mandatory in all cases diagnosed with ovarian cancer.

    To perform a retrospective analysis of a series of complicated JID (jejunoileal diverticulitis) cases surgically treated in our service during the period from 2002 to 2015. We treated 12 cases of jejunoileal complicated diverticulosis. 7 women and 5 men. The mean age was 76 years. The clinical presentation in all cases was acute abdominal pain, one with gastrointestinal bleeding. All cases had leukocytosis, neutrophilia and increased acute phase reactants. All patients underwent emergency abdominal CT. In 11 cases, there was consistency between imaging studies and surgical findings. Diverticula were located: jejunum (9) and ileum (3). Urgent exploratory laparotomy was always done and findings were: diverticular perforation with peritonitis (7 cases), diverticular perforation with abscess (4 cases) and in one case an ischemic area with diverticular perforation after embolization. Intestinal resection and anastomosis was performed in all cases. There were no patients, in which the diagnosis of diverticulosis jejunoileal was previously known. Complications were: Clavien I (2), Clavien IIIa (1), Clavien IVb (1), Clavien V (1). Jejunoileal diverticulitis is a rare entity, usually the first sign of onset of diverticular disease not previously known. Abdominal CT is of great diagnostic value. Resection of the affected segment is the treatment of choice.

    The present investigation was aimed at studying the efficacy of cognitive behavior therapy (CBT) in reducing the symptoms of stuttering and dysfunctional cognitions and in enhancing assertiveness and quality of life in clients with stuttering. Five clients with stuttering who met the inclusion criteria (male clients with diagnosis of stuttering) and exclusion criteria (clients with brian damage), substance abuse or mental retardation were enrolled for the study. A single-case design was adopted. The pre-, mid- and post-assessment were carried out using Stuttering Severity Scale (SSI), Perception of Stuttering Inventory (PSI), Beck's Anxiety Inventory (BAI), Dysfunctional Attitude (DAS), Fear of Negative Evaluation (FNE), Assertiveness Scale (AS), Rosenberg's Self-Esteem Scale (RSES), and World Health Organization - Quality of Life Scale (WHO-QOL). Five clients received cognitive behavioral intervention comprising of psycho-education, relaxation, deep breathing, humming, prolongation, cognitive restructuring, problem-solving strategies and assertiveness. At post-treatment assessment, there was improvement. The findings of the study are discussed in the light of available research work, implications, limitations of the study and suggestions for future research.

    Full Text Available Eosinophilic Gastroenteritis is a rare disease characterized by infiltration of the gastrointestinal tract by an increased number of eosinophils as compared to the normal. The anatomic location and intensity of the infiltrate decides the varied clinical symptomatology with which these patients present. The present report deals with four cases, all presenting with clinical signs of intestinal obstruction A laparotomy performed revealed a stricture in the first case, superficial ulcers and adhesions in the second case, an ileocaecal mass in the third case and volvulus formation in the fourth case. Eosinophilic gastroenteritis was confirmed on histopathology in all the four cases. All the four patients experienced relief of symptoms after resection. It is essential to diagnose the disease to differentiate it from other conditions presenting as intestinal obstruction. The cases are presented because of the rarity of occurrence and presentation. Relevant literature has been reviewed.

    Full Text Available Cesario Bellantuono, Francesca Bozzi, Laura Orsolini Psychiatric Unit and DEGRA Center, United Hospital and Academic Department of Experimental and Clinical Medicine, Polytechnic University of Marche, Ancona, Italy Background: The aim of this paper is to report maternal and neonatal outcomes in pregnant women treated with escitalopram during pregnancy and breastfeeding. Methods: Women enrolled in the DEGRA Database at the Clinic of Affective Disorders in Pregnancy and Postpartum in Italy, treated during pregnancy with escitalopram and followed up throughout pregnancy, were included in this study. All patients provided written informed consent and the study was approved by the local ethics committee. Psychiatric diagnoses were assessed using the Structured Clinical Interview for DSM-IV (Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition Axis I Disorders and symptoms were assessed using the Hamilton Rating Scale for Depression (17 items and Hamilton Rating Scale for Anxiety (14 items. Clinical and sociodemographic characteristics as well as maternal and neonatal outcomes were recorded. Results: The case histories of seven pregnant women treated for depression and/or anxiety disorders with escitalopram were reported. Four women were also treated with benzodiazepines. All pregnancies were full-term and all newborns had normal Apgar scores. There were no major malformations or miscarriages following exposure to escitalopram. Mild withdrawal syndrome was reported only in a newborn who was also exposed to a benzodiazepine. Two infants exposed to escitalopram during breastfeeding did not show any health problems. Conclusion: Our experience with use of escitalopram in pregnant women did not reveal any maternal or neonatal concerns. However, considering the few cases analyzed and the paucity of published literature, no conclusions can be drawn on its safety profile in pregnancy and breastfeeding.

    Classically, the onset of head tremor in essential tremor (ET) patients follows that of hand tremor, such that there is a somatotopic spread of involved areas. Here we present a series of seven self-reportedly "unaffected" relatives of ET cases. These seven were clinically asymptomatic and had normal levels of arm tremor on examination, yet each evidenced a transient head wobble on examination. We estimate the prevalence of this phenotype within the two studies from which cases were ascertained. ET cases and their self-reportedly affected and unaffected relatives, enrolled in two family studies, underwent a medical history and videotaped neurological examination. In seven self-reportedly "unaffected" relatives, a transient and subtle head wobble was seen, always during sustained phonation, speech, or reading aloud. Total tremor score (a measure of arm tremor) ranged from 5 to 12 (i.e., mild tremor within the range of normal). The prevalence of this phenotype of early head tremor was 3.7% in one study and 23.1% in the other. We present a series of seven individuals who had early head tremor in an evolving transition state from normal to ET. These cases raise a number of broad clinical, phenotypic, and pathophysiological issues about ET.

  20. Simulation of the Grazing Effects on Grassland Aboveground Net Primary Production Using DNDC Model Combined with Time-Series Remote Sensing Data—A Case Study in Zoige Plateau, China

    Full Text Available Measuring the impact of livestock grazing on grassland above-ground net primary production (ANPP is essential for grass yield estimation and pasture management. However, since there is a lack of accurate and repeatable techniques to obtain the details of grazing locations and stocking rates at the regional scale, it is an extremely challenging task to study the influence of regional grazing on the grassland ANPP. Taking Zoige County as a case, this paper proposes an approach to quantify the spatial and temporal variation of grazing intensity and grazing period through time-series remote sensing data, simulated grassland ANPP through the denitrification and decomposition (DNDC model, and then explores the impact of grazing on grassland ANPP. The result showed that the model-estimated ANPP while considering grazing had a significant relationship with the field-observed ANPP, with the coefficient of determination (R2 of 0.75, root mean square error (RMSE of 122.86 kgC/ha, and average relative error (RE of 8.77%. On the contrary, if grazing activity was not considered in simulation, a large uncertainty was found when the model-estimated ANPP was compared with the field observation, showing R2 of 0.4, RMSE of 211.51 kgC/ha, and average RE of 32.5%. For the whole area of Zoige County in 2012, the statistics of the estimation showed that the total regional ANPP was up to 3.815 × 105 tC, while the total regional ANPP, without considering grazing, would be overestimated by 44.4%, up to 5.51 × 105 tC. This indicates that the grazing parameters derived in this study could effectively improve the accuracy of ANPP simulation results. Therefore, it is feasible to combine time-series remote sensing data with the process model to simulate the grazing effects on grassland ANPP. However, some issues, such as selecting proper remote sensing data, improving the quality of model input parameters, collecting more field data, and exploring the data assimilation

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    Full Text Available Intraoral fibrous overgrowths of the soft tissues are relatively common and may be benign reactive or neoplastic lesions. A series of 10 lesions is presented which included pyogenic granuloma, fibroma and peripheral ossifying fibroma. Almost all the lesions occurred in the second and third decades and were present in the anterior segment of the jaws, with a distinct female predilection. Majority of these lesions were asymptomatic and the patients reported for treatment only due to the discomfort during function. Histopathologic examinations were done for diagnosis of these lesions. Surgical excision along with removal of causative irritants remains the treatment of choice. The extent of excision should depend on the severity of the lesion, as some of these lesions have a tendency for recurrence. All the patients in this series were closely followed up for a period of 2 years and showed no signs of recurrence.

    To evaluate the outcomes of treating deep recalcitrant fungal keratitis with intrastromal voriconazole injection. Twenty-five patients with culture proven fungal keratitis, not responding to a combination of topical 5% natamycin and 1% voriconazole were treated with intrastromal voriconazole (50 µg/0.1 mL) injected in five divided doses around the infiltrate to form a depot of the drug around the circumference of the lesion. The mean age of the patients was 52.52±12.21 years and mean time to presentation was 17.12±13.75 days from the onset of symptoms. The mean area of the infiltrate was 30.41±17.2 mm(2), hypopyon was present in 88% and all cases had infiltrates that extended beyond the mid-stromal level. Intrastromal voriconazole helped to resolve the infection in 18 (72%) patients and about 15% of these needed more than one injection. Smaller ulcers responded better to treatment. Fusarium spp were responsible for six of the seven cases that failed treatment. Targeted delivery of voriconazole by intrastromal injection (50 µg/0.1 mL) is a safe and effective way to treat deep recalcitrant fungal keratitis, though some may need repeated injections. Fusarium keratitis may show suboptimal response but this needs further study. Published by the BMJ Publishing Group Limited.

    2012-01-01

    This systematic review was aimed at critically evaluating the evidence regarding the adverse effects associated with aromatherapy. Five electronic databases were searched to identify all relevant case reports and case series. Forty two primary reports met our inclusion criteria. In total, 71 patients experienced adverse effects of aromatherapy. Adverse effects ranged from mild to severe and included one fatality. The most common adverse effect was dermatitis. Lavender, peppermint, tea tree oil and ylang-ylang were the most common essential oils responsible for adverse effects. Aromatherapy has the potential to cause adverse effects some of which are serious. Their frequency remains unknown. Lack of sufficiently convincing evidence regarding the effectiveness of aromatherapy combined with its potential to cause adverse effects questions the usefulness of this modality in any condition.

    Chikungunya (CHIK) is a mosquito-borne virus (CHIKV) infection that recently appeared in the Americas and thousands of confirmed cases have been reported in Brazil since the first autochthonous cases were reported in September 2014. We reported four cases of CHIK in kidney transplant recipients. The diagnosis was confirmed by positive CHIKV real-time polymerase chain reaction in two cases and positive CHIKV-IgM serology in two patients. The time between transplantation and CHIKV infection ranged from 2 to 11 years. All of them had arthralgia, and 3 of them had fever. Other symptoms were mild conjunctivitis, rash, and retro-orbital pain. Kidney function remained stable in all cases. In three patients prednisone doses were temporally increased and the symptoms disappeared concurrently with the increase of the dose. As for the fourth patient, the prednisone dose remained unchanged and yet she improved. Other immunosuppressive drugs were not changed for the four cases. As far as we know, there are only two previously reported cases of CHIK among solid organ transplant recipients besides the four cases reported here. Despite the small number of cases, we can speculate that the use of immunosuppression might have played a role in the paucity of symptoms and the gradual complete recovery with no complication.

    Time series analysis and modelling represent a large study field, implying the approach from the perspective of the time and frequency, with applications in different domains. Modelling hydro-meteorological time series is difficult due to the characteristics of these series, as long range dependence, spatial dependence, the correlation with other series. Continuous spatial data plays an important role in planning, risk assessment and decision making in environmental management. In this context, in this book we present various statistical tests and modelling techniques used for time series analysis, as well as applications to hydro-meteorological series from Dobrogea, a region situated in the south-eastern part of Romania, less studied till now. Part of the results are accompanied by their R code. .

    Full Text Available Background: Khat chewing is common especially among men in East Africa and Yemen. It is generally viewed by the populace as a benign social custom. Several studies of ethnic Somali immigrants to Western countries suggest an association between khat chewing and hepatotoxicity, but the risk of hepatotoxicity related to khat chewing within African settings is not documented.Aim: To identify and describe liver disease without evidence of alcohol exposure or infectious etiology in khat chewers.Settings: A university-affiliated teaching hospital in Somaliland.Methods: Cases of cirrhosis of unknown cause were identified from the clinical practice of Al Hayatt Hospital in Borama, Somaliland, during 14 months beginning December 2012.Results: Eight Somali men aged 27–70 years living in Somaliland were identified with cirrhosis of otherwise unknown cause. All chewed khat habitually for many years (15–128 bundles per day times years of use. A liver biopsy of one man was consistent with khat hepatotoxicity. Four of the eight men died during the study period.Conclusion: Khat chewing may be associated with health consequences including severe hepatotoxicity with cirrhosis.

    Brucellosis is one of the main neglected zoonotic diseases. Several factors may contribute to the epidemiology of brucellosis. Imported cases, mainly in travellers but also in recently arrived immigrants, and cases associated with imported products, appear to be infrequently reported. Cases of brucellosis diagnosed at a referral unit for imported diseases in Europe were described and a review of the literature on imported cases and cases associated with contaminated imported products was performed. Most imported cases were associated with traditional risk factors such as travel/consumption of unpasteurized dairy products in endemic countries. Cases associated with importation of food products or infected animals also occurred. Although a lower disease incidence of brucellosis has been reported in developed countries, a higher incidence may still occur in specific populations, as illustrated by cases in Hispanic patients in the USA and in Turkish immigrants in Germany. Imported brucellosis appears to present with similar protean manifestations and both classical and infrequent modes of acquisition are described, leading on occasions to mis-diagnoses and diagnostic delays. Importation of Brucella spp. especially into non-endemic areas, or areas which have achieved recent control of both animal and human brucellosis, may have public health repercussions and timely recognition is essential.

    Homicide-suicides or "dyadic deaths" refer to a homicide followed by the suicide of the perpetrator within 1 week of the homicide. A unique subset is filicide-suicide: a parent kills his/her child before committing suicide. Shooting is the preferred method for both the homicide and suicide. The perpetrator has depression in most cases.We present 3 cases of filicide-suicide. In case 1, a divorced mother with schizophrenia and bipolar disorder shot her son and herself. In case 2, a father shot his son and himself while involved in a child-custody dispute. In case 3, a father, experiencing a divorce and financial difficulties, and his daughter with Angelman syndrome succumbed to carbon monoxide poisoning.The forensic pathologist should be aware of the psychosocial dynamics that interplay in filicide-suicide. Diligent attention to a parent's life stressors may aid in determining risk factors for filicide-suicide.

    Full Text Available Abstract Introduction Until now, studies on paracetamol given intravenously have mainly been performed with the pro-drug propacetamol or with paracetamol in preterm babies above 32 weeks of gestation. Studies in these babies indicate that intravenous paracetamol is tolerated well, however studies on the efficacy of intravenous paracetamol are lacking. There are no pharmacokinetic data on the administration of multiple doses of paracetamol in preterm babies with a gestational age below 32 weeks. Case presentation We present a case series of nine Caucasian preterm babies, six boys and three girls, with a mean gestational age of 28.6 weeks (range 25.9 to 31.6 weeks. Case one, a girl with a gestational age of 25 weeks and six days, presented with necrotizing enterocolitis. In the second case, a female baby with a gestational age of 26 weeks and two days presented with hematoma. In case three, a female baby with a gestation of 26 weeks and one day developed intraventricular hemorrhage. In case four, a male baby with a gestational age of 31 weeks and four days presented with pain after vacuum delivery. Case five, a female baby born after a gestation of 29 weeks and six days presented with hematoma. In case six, a male baby with a gestation of 30 weeks and six days presented with hematoma. In case seven, a male baby, born with a gestational age of 30 weeks and six days, presented with caput succedaneum and hematoma. In case eight, a male baby, born after a gestation of 28 weeks and four days, developed abdominal distention. Case nine, a female baby, born with a gestational age of 27 weeks and three days presented with hematoma. These babies were treated with intravenous paracetamol 15 mg/kg every six hours. Serum concentrations and aspartate transaminase were determined after prolonged administration. Pain scores were assessed using the Premature Infant Pain Profile. Conclusion Paracetamol serum concentrations ranged from 8 to 64 mg/L after eight to 12

    The aim of this study is to model the association between weekly time series of dengue case counts and meteorological variables, in a high-incidence city of Colombia, applying Bayesian hierarchical dynamic generalized linear models over the period January 2008 to August 2015. Additionally, we evaluate the model's short-term performance for predicting dengue cases. The methodology shows dynamic Poisson log link models including constant or time-varying coefficients for the meteorological variables. Calendar effects were modeled using constant or first- or second-order random walk time-varying coefficients. The meteorological variables were modeled using constant coefficients and first-order random walk time-varying coefficients. We applied Markov Chain Monte Carlo simulations for parameter estimation, and deviance information criterion statistic (DIC) for model selection. We assessed the short-term predictive performance of the selected final model, at several time points within the study period using the mean absolute percentage error. The results showed the best model including first-order random walk time-varying coefficients for calendar trend and first-order random walk time-varying coefficients for the meteorological variables. Besides the computational challenges, interpreting the results implies a complete analysis of the time series of dengue with respect to the parameter estimates of the meteorological effects. We found small values of the mean absolute percentage errors at one or two weeks out-of-sample predictions for most prediction points, associated with low volatility periods in the dengue counts. We discuss the advantages and limitations of the dynamic Poisson models for studying the association between time series of dengue disease and meteorological variables. The key conclusion of the study is that dynamic Poisson models account for the dynamic nature of the variables involved in the modeling of time series of dengue disease, producing useful

    2016-01-01

    Full Text Available Cerebral air embolism (CAE is an infrequently reported complication of routine medical procedures. We present two cases of CAE. The first patient was a 55-year-old male presenting with vomiting and loss of consciousness one day after his hemodialysis session. Physical exam was significant for hypotension and hypoxia with no focal neurologic deficits. Computed tomography (CT scan of head showed gas in cerebral venous circulation. The patient did not undergo any procedures prior to presentation, and his last hemodialysis session was uneventful. Retrograde rise of venous air to the cerebral circulation was the likely mechanism for venous CAE. The second patient was a 46-year-old female presenting with fever, shortness of breath, and hematemesis. She was febrile, tachypneic, and tachycardic and required intubation and mechanical ventilation. An orogastric tube inserted drained 2500 mL of bright red blood. Flexible laryngoscopy and esophagogastroduodenoscopy were performed. She also underwent central venous catheter placement. CT scan of head performed the next day due to absent brain stem reflexes revealed intravascular air within cerebral arteries. A transthoracic echocardiogram with bubble study ruled out patent foramen ovale. The patient had a paradoxical CAE in the absence of a patent foramen ovale.

    This study is to explore the clinical characteristics, laboratory diagnosis, and treatment outcomes in pediatric patients with non-diabetic ketoacidosis. Retrospective patient chart review was performed between March 2009 to March 2015. Cases were included if they met the selection criteria for non-diabetic ketoacidosis, which were: 1) Age ≤ 18 years; 2) urine ketone positive ++ or >8.0 mmol/L; 3) blood ketone >3.1 mmol/L; 4) acidosis (pH diabetic ketoacidosis and were included in the report. Five patients with 7 episodes of non-diabetic ketoacidosis were identified. They all presented with dehydration, poor appetite, and Kussmaul breathing. Patients treated with insulin plus glucose supplementation had a quicker recovery from acidosis, in comparison to those treated with bicarbonate infusion and continuous renal replacement therapy. Two patients treated with bicarbonate infusion developed transient coma and seizures during the treatment. Despite normal or low blood glucose levels, patients with non-diabetic ketoacidosis should receive insulin administration with glucose supplementation to correct ketoacidosis.

    2016-12-01

    Full Text Available In the context of medical professional liability, obstetrics is one of the most involved medical specialties because the unfavorable outcome of a pregnancy is difficult to accept for parents, who tend to reduce it to inappropriate care that occurred during pregnancy or birth. 32 cases of perinatal asphyxia were evaluated by the Institute of Forensic Medicine in Brescia during the period between 1999 and 2014 (13 in Civil Court and 19 in Penal Court. 9 out of the 32 pregnancies were twins, so the considerations were carried out on a total of 41 fetuses/newborns. Profiles of inadequacy were identified in 66% of cases (85% of the cases evaluated in Civil Court; 53% of the cases evaluated in Penal Court. The existence of a causal relationship between the medical conduct and the onset of asphyxia was recognized in 79% of civil cases and in 38% of penal cases. There is a “greater rigor” in the verification of causal relationship and malpractice profiles in penal cases compared to civil ones: this is in harmony with the most recent Italian Court decisions, characterized by compelling suspect’s protection in the presence of a reasonable doubt in criminal matters and by victim’s protection in civil ones.

    Full Text Available Introduction: Lymphadenopathy is a common clinical problem in pediatric age group. Tuberculous lymphadenopathy is a prominent cause of peripheral adenopathy amongst children in the developing countries. Tuberculous lymphadenitis is among the most frequent presentations of extrapulmonary tuberculosis. In this article, we presented five pediatric cases with mycobacterial infection detected in cervical lymph nodes.Case Presentation: First case admitted with a painless swelling in cervical and axillar regions and pathologic examination of the extirpated lymph node showed necrotizing granulomatous lymphadenitis. Second case presented with two months history of abdominal pain and painless swelling of right cervical region and Mycobacterium tuberculosis (MTB was grown in culture from the lymph node. Third case admitted with a painless cervical mass, her sputum was found positive for MTB. Fourth case was admitted with one year history of swelling that became fistulized in 6 months and lymph node culture was found positive for MTB. Fifth case, admitted with a painful swelling in left upper gingival mucosa and extirpated lymph node showed chronic granulomatous inflammation.Conclusion: Pathological and microbiological examination of tissues such as cervical enlarged lymph nodes should be evaluated for diagnosis of tuberculous infections.

    Arthroscopic labral repair in the shoulder has become commonplace in recent years. A variety of implants have evolved in parallel with arthroscopic techniques. Any orthopedic implant that is placed in close proximity to the joint has the potential to cause subsequent damage to the articular surface if it is left prominent or dislodges secondary to improper surgical technique. This article focuses on a series of implant-related complications of labral surgery and their subsequent management. Additionally, correct patient selection and surgical technique are discussed.

    Full Text Available Abstract Because metaplastic carcinoma of the breast encompasses a great variety of histopathology, diagnostic challenges abound, especially within the realm of cytology. The authors compiled and studied an eight-case series comprised of metaplastic breast carcinomas and lesions initially suspicious cytologically for metaplastic carcinoma in order to assess the degree of cytologic-histologic correlation and to identify recurring problematic themes surrounding the cytology-based diagnosis of this neoplasm. The cytologic and histologic slides from eight cases suspicious for metaplastic breast carcinoma diagnosed by fine needle aspiration (FNA were collected and analyzed through a seven-year retrospective search of case files at our institution. Based on cytologic characteristics, the cases were separated into three groups. Group 1 consisted of three cases presenting with poorly differentiated adenocarcinoma and squamoid components on FNA. Group 2 was composed of two cases that featured a monophasic, malignant ductal cell population on cytology, while the cytologic specimens for the third group of cases presented with a mesenchymal component with or without a malignant glandular constituent. Cytologic-histologic correlation was present in two of three cases demonstrating a mesenchymal component, and there was 100% sensitivity in the cytologic detection of those mesenchymal elements. However, in only one of three cases was there an accurate cytologic diagnosis of metaplastic carcinoma when squamoid changes were present on FNA. Both cases demonstrating only malignant glandular elements on cytologic specimens revealed an additional component of malignant squamous differentiation upon the examination of mastectomy-derived tissue. These results indicate that squamous-like changes identified on FNA should be interpreted with caution and that sampling error remains a problematic recurrence in cytology. Regardless, there appears to be promise concerning

    Hypopigmented mycosis fungoides (hMF) is a rare subtype of mycosis fungoides. The aim of this study was to identify the clinical-epidemiological profile of our patient group and also to provide additional information about treatment responses and prognosis. This is a cross-sectional retrospective observational study, with exploratory analysis. The outcome variables were disease progression and related death. Twenty patients with hMF were selected from a group of 102 patients diagnosed with MF. There was no gender difference (10 females and 10 males). Mean age at diagnosis was 43.85 years, and most patients had mixed or black skin color. The mean time between the onset of the lesions and the diagnosis was 66.75 months. Patients were equally distributed in stages IA (50%) and IB (50%). Photochemotherapy (psoralen and ultraviolet A) was the predominant therapeutic modality. The mean follow-up time was 7.25 years. In 10%, disease progression was observed. Death related to the disease occurred in one patient. The clinical and epidemiological profile of patients with hypopigmented MF found in our sample is in agreement with what is described in the literature, with the exception of the age at diagnosis, higher than expected. Diagnostic delay time, despite long, is also consistent with the medical literature; however, in this sample, we had two cases of disease progression, with death of one patient, despite the treatment, which is extremely important since hypopigmented MF is usually associated with good prognosis. © 2018 The International Society of Dermatology.

    Primary orbital melanoma (POM) is a very rare condition. We report further four cases and review all previously reported cases. We present a multicentre retrospective review of patients with POM. Clinical, radiological, surgical, histological, and follow-up data is presented. Four patients with POM were identified between 2000 and 2013. All presented with proptosis and diplopia without reduced vision. Two had known pre-existing blue cell naevi. All were stage T1N0M0. All underwent exenteration with adjuvant radiotherapy. All are disease free at follow-up durations of 24-151 months. The present three cases and review of all cases in the literature suggest a higher likelihood of disease-free survival from primary exenteration (7/8 disease-free survival, 1/8 death from metastatic disease) than wide local excision (7/16 disease-free survival, 9 recurrence or metastasis of whom 4 died). Adjuvant radiotherapy may additionally improve outcomes.

    The incidence of melanoma in children is uncommon, being particularly rare in children under 10 years-old. However, this disease is increasing by a mean of 2% per year. As in adults, the lymph node status is the most important prognostic factor, crucial to performing the selective sentinel lymph node biopsy (SLNB). We report 3 cases of paediatric patients of 3, 4 and 8 years-old, in which SLNB was performed for malignant melanoma. Paediatric age implies greater technical difficulty to the scintigraphy scan due to poor patient cooperation, with mild sedation required in some cases, and only being able to acquire planar images in other cases. SPECT/CT was only performed in the oldest patient. In our cases, SLNB was useful for selecting the least invasive surgery in order to reduce morbidity.

    We describe the cases of four patients with eating disorders in whom complex interactions occurred among religious faith, pathogenesis of the eating disorder, and clinical management. In some of the cases, religious beliefs seemed to provide a containment of maladaptive behaviors, partly through prayer and through a sense of belonging to the religious community. In other cases, it proved difficult to separate the concept of a punitive God from the illness process. The cases are discussed with reference to a limited empirical literature. Similarities are noted between some religious institutions and eating disorder treatment regimes. This paper explores management issues, including the use of pastoral counseling and the ethics of addressing religious beliefs in therapy. We note the benefits of a rapprochement between psychiatry and religion. Copyright 2000 by John Wiley & Sons, Inc.

    There have been documented cases of serious and life-threatening health effects due to patients taking unintentional analgesia overdose secondary to dental pain. We aimed to determine firstly what proportion of unintentional paracetamol overdose cases admitted to an acute medical assessment unit (MAU) were secondary to dental pain, secondly what proportion of such cases encountered barriers to accessing emergency dental care and finally what clinical burden such cases placed on the hospital services. The clinical coding department provided information to allow appropriate identification and data collection from patient discharge summaries and case notes of all unintentional paracetamol overdose cases secondary to dental pain over a 24 month period (1 March 2012 to 28 February 2014). One hundred and sixteen admissions were identified specifically for unintentional paracetamol overdose. Dental pain accounted for 48 (41%) of all cases. Females (67%) were twice as likely to be admitted, compared to males (33%), with a mean age of 36 years and four months. Thirty-two (63%) non-dentally registered and all nine (100%) registered patients were unable to access timely emergency dental care before their admission. Forty cases (83%) were referred to the hospital oral and maxillofacial services (OMFS). Thirty-seven (93%) patients underwent elective outpatient dental extractions and the remaining three (7%) patients were admitted for intravenous antibiotics, incision and drainage and dental extractions. All patients were treated under local anaesthetic. Dental pain is the single most common cause of acute medical admission secondary to unintentional paracetamol overdose. Patients registered with a general dental practitioner (GDP), as well as those not registered with a GDP, had difficulty accessing timely emergency primary dental care.

    The aim of this case-series study is to evaluate the prevalence of mucositis, peri-implantitis, and survival and success rates of oxide-coated implants in subjects treated for periodontitis. Twenty-four subjects treated for generalized chronic periodontitis (GCP) and five treated for generalized aggressive periodontitis (GAP) were orally rehabilitated with a total of 130 dental implants. Subjects were examined 2 to 4 weeks prior to extraction of non-retainable teeth and at insertion of superstructure. Additional examinations were performed during a 3-month recall schedule over a 3- to 6-year follow-up period. Radiographs were taken after insertion of the superstructure and 1, 3, and 5 years later. The results showed implant survival rates of 97.1% in GCP subjects versus 96.2% in GAP subjects. The implant success rate was 77.9% in GCP subjects and 38.5% in GAP subjects. In GCP subjects, mucositis was present in 7.7% and peri-implantitis in 12.5% of the implants. In GAP subjects, 28.0% of the implants showed mucositis and 32.0% peri-implantitis. Implant failure, mucositis, and peri-implantitis were more evident in GAP subjects. Peri-implantitis was more prevalent for implants in the maxilla and implants >10 mm. After 5 years, the mean peri-implant bone loss in GAP subjects was 2.89 mm and in GCP subjects 1.38 mm. Periodontally diseased subjects treated in a supportive periodontal therapy can be successfully rehabilitated with oxide-coated dental implants for a follow-up period of 3- to 6-years. Implants in the maxilla and GAP subjects were more susceptible to mucositis and peri-implantitis, with lower implant survival and success rates.

    Until now, studies on paracetamol given intravenously have mainly been performed with the pro-drug propacetamol or with paracetamol in preterm babies above 32 weeks of gestation. Studies in these babies indicate that intravenous paracetamol is tolerated well, however studies on the efficacy of intravenous paracetamol are lacking. There are no pharmacokinetic data on the administration of multiple doses of paracetamol in preterm babies with a gestational age below 32 weeks. We present a case series of nine Caucasian preterm babies, six boys and three girls, with a mean gestational age of 28.6 weeks (range 25.9 to 31.6 weeks). Case one, a girl with a gestational age of 25 weeks and six days, presented with necrotizing enterocolitis. In the second case, a female baby with a gestational age of 26 weeks and two days presented with hematoma. In case three, a female baby with a gestation of 26 weeks and one day developed intraventricular hemorrhage. In case four, a male baby with a gestational age of 31 weeks and four days presented with pain after vacuum delivery. Case five, a female baby born after a gestation of 29 weeks and six days presented with hematoma. In case six, a male baby with a gestation of 30 weeks and six days presented with hematoma. In case seven, a male baby, born with a gestational age of 30 weeks and six days, presented with caput succedaneum and hematoma. In case eight, a male baby, born after a gestation of 28 weeks and four days, developed abdominal distention. Case nine, a female baby, born with a gestational age of 27 weeks and three days presented with hematoma. These babies were treated with intravenous paracetamol 15 mg/kg every six hours. Serum concentrations and aspartate transaminase were determined after prolonged administration. Pain scores were assessed using the Premature Infant Pain Profile. Paracetamol serum concentrations ranged from 8 to 64 mg/L after eight to 12 doses of intravenous paracetamol. Adequate analgesia was obtained in

    To describe the clinical characteristics of a series of patients presenting conversion disorder in a general internal medicine ward and outpatient clinic, the arguments retained by the physicians in favour of the diagnosis, the somatic and psychiatric co-morbidities, the management and the outcome of the disorder. We report the study of 37 patients diagnosed with conversion disorder in an internal medicine department of a French university hospital over a period of 14 years. We retrospectively reviewed the charts of the patients and contacted their primary care physicians to obtain follow-up data. No structured instrument was used for the diagnosis of conversion disorder or for the assessment of psychiatric comorbidities. As expected, patients were mostly young females, although a great variety of age, gender, and socio-cultural background was observed. Motor symptoms predominated (62%). A relevant psychogenic factor was explicitly mentioned in only 43% of the cases. In many cases, organic disease was also present, and an organic cause for the symptom initially considered as conversion was suspected in 3 cases. Depressive and anxious disorders were present respectively in 38% and 35% of cases. A pain complaint was associated in half of the cases. Among patients for whom follow-up data is available, conversion symptoms persisted or recurred in 70% of cases and were associated with a poor quality of life. This case series confirms that the DSM-IV-TR criterion of "psychogenicity" (later abandoned in DSM-5) is highly problematic in clinical practice. It suggests a close relationship between conversion disorder and unexplained chronic pain. Copyright © 2015 L’Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

    Describe a series of atypical presentations of pandemic influenza A (H1N1) 2009. Description of case series using hospital records. Six patients aged 1 to 65 years with confirmed pandemic influenza A (H1N1) 2009 infection presented with neurological complications within 2 to 5 days after the first signs of influenza-like illness. All six were admitted with seizures or altered mental status. No abnormalities were found in brain scans or cerebral spinal fluid studies of any of the six. All were discharged without sequelae within days of admission. This is only the second report of pandemic influenza presenting with neurological manifestations. Clinicians caring for patients when pandemic influenza is prevalent in their communities should maintain a high level of awareness of the potential atypical presentations with which this disease can appear.

    Full Text Available Abstract Introduction Neurofibromatosis type 1 is an autosomal dominant disorder that occurs across all ethnic groups and affects approximately one in 4000 individuals. One of the most noticeable characteristics of the disease is the development of neurofibromas. Case presentation A total of 258 patients (131 women, 127 men with neurofibromatosis type 1 were evaluated between 1994 and 2004 in our hospital's dermatology department. Nine patients (3.45%, 95% confidence limits 1.22 to 5.68 had neurofibromas of the breast. One of these nine patients presented with an extensive congenital plexiform neurofibroma in the outer quadrants of her right breast, extending to the nipple-areolar complex. Meanwhile, three patients had more than one neurofibroma on the nipple-areolar complexes. Three patients had a family history of neurofibroma. Over the years 1994 to 2004, the cutaneous lesions were not associated with any malignancies. Presenting symptoms were related to conditions such as increasing size of the mass, and associated loss of function and pain. Conclusions This study suggests that the changes are limited to particular subgroups. That neurofibromatosis is more prevalent in women (7 women and 2 men suggests that being female could be a susceptibility factor for the development of neurofibromas of the nipple-areolar complexes. There are few reports in the literature describing breast carcinomas in association with von Recklinghausen disease. It has been speculated that the presence of multiple neurofibromas of the breast may obscure a breast mass at palpation, leading to a delay in clinical detection. We suggest that patients with neurofibromas of the breast have more rigorous clinical and mammographic screening of the breast during adulthood to determine the presence or absence of malignancies. The finding that both the neurofibromatosis type 1 gene and a breast cancer predisposition gene are located in close proximity on chromosome 17q makes the

    Full Text Available Abstract Background The first chiropractic adjustment given in 1895 was reported to have cured deafness. This study examined the effects of a single, initial chiropractic visit on the central nervous system by documenting clinical changes of audiometry in patients after chiropractic care. Case presentation Fifteen patients are presented (9 male, 6 female with a mean age of 54.3 (range 34–71. A Welch Allyn AudioScope 3 was used to screen frequencies of 1000, 2000, 4000 and 500 Hz respectively at three standard decibel levels 20 decibels (dB, 25 dB and 40 dB, respectively, before and immediately after the first chiropractic intervention. Several criteria were used to determine hearing impairment. Ventry & Weinstein criteria of missing one or more tones in either ear at 40 dB and Speech-frequency criteria of missing one or more tones in either ear at 25 dB. All patients were classified as hearing impaired though greater on the right. At 40 dB using the Ventry & Weinstein criteria, 6 had hearing restored, 7 improved and 2 had no change. At 25 dB using the Speech-frequency criteria, none were restored, 11 improved, 4 had no change and 3 missed a tone. Conclusion A percentage of patients presenting to the chiropractor have a mild to moderate hearing loss, most notably in the right ear. The clinical progress documented in this report suggests that manipulation delivered to the neuromusculoskeletal system may create central plastic changes in the auditory system.
