    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.

    Vaccine safety studies are often electronic health record (EHR)-based observational studies. These studies often face significant methodological challenges, including confounding and misclassification of adverse event. Vaccine safety researchers use self-controlled case series (SCCS) study design to handle confounding effect and employ medical chart review to ascertain cases that are identified using EHR data. However, for common adverse events, limited resources often make it impossible to adjudicate all adverse events observed in electronic data. In this paper, we considered four approaches for analyzing SCCS data with confirmation rates estimated from an internal validation sample: (1) observed cases, (2) confirmed cases only, (3) known confirmation rate, and (4) multiple imputation (MI). We conducted a simulation study to evaluate these four approaches using type I error rates, percent bias, and empirical power. Our simulation results suggest that when misclassification of adverse events is present, approaches such as observed cases, confirmed case only, and known confirmation rate may inflate the type I error, yield biased point estimates, and affect statistical power. The multiple imputation approach considers the uncertainty of estimated confirmation rates from an internal validation sample, yields a proper type I error rate, largely unbiased point estimate, proper variance estimate, and statistical power. © 2018 WILEY-VCH Verlag GmbH & Co.

    Although the exact incidence of pediatric oral lichen planus (OLP) is unknown, the oral mucosa seems to be less commonly involved, and the clinical presentation is often atypical. The aim of the study is to present a case series of OLP in childhood. From our database, we retrospectively selected and analyzed the clinical data of OLP patients under the age of 18 where the diagnosis had been confirmed by histopathological analysis. The case series from our database shows eight patients, four males and four females. The mean (±SD) age at the time of diagnosis of the disease was 13.5 (±2.73) years, ranging in age from 9 to 17. Clinically, a reticular pattern was present in six patients (75%), and the tongue was the most commonly involved oral site (six cases, 75%). We also report the first case of OLP in a 9-year-old girl affected by autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy. We report the largest case series of pediatric OLP published in literature thus far. Differences in the disease between adults and pediatric patients have been detected, but further investigation and a larger case series are needed to establish any detailed differences in clinical outcomes. © 2017 The International Society of Dermatology.

    While previously believed to be mutually exclusive, concomitant mutation of Kirsten rat sarcoma viral oncogene homolog (KRAS)- and V-raf murine sarcoma b-viral oncogene homolog B1 (BRAF)-mutated colorectal carcinoma (CRC), has been described in rare instances and been associated with advanced-stage disease. The present case series is the first to report on the implications of concurrent KRAS/BRAF mutations among surgically treated patients, and the largest set of patients with surgically treated colorectal liver metastasis (CRLM) and data on KRAS/BRAF mutational status thus far described. We present cases from an international, multi-institutional cohort of patients that underwent hepatic resection for CRLM between 2000-2015 at seven tertiary centers. The incidence of KRAS/BRAF mutation in patients with CRLM was 0.5% (4/820). Of these cases, patient 1 (T2N1 primary, G13D/V600E), patient 2 (T3N1 primary, G12V/V600E) and patient 3 (T4N2 primary, G13D/D594N) succumbed to their disease within 485, 236 and 79 days respectively, post-hepatic resection. Patient 4 (T4 primary, G12S/G469S) was alive 416 days after hepatic resection. The present case series suggests that the incidence of concomitant KRAS/BRAF mutations in surgical cohorts may be higher than previously hypothesized, and associated with more variable survival outcomes than expected.

    Ocular tuberculosis is a rare form of extra pulmonary tuberculosis. It represents 1-2% of all clinical forms. The aim of this work was to focus on diagnostic and therapeutic characteristics of ocular tuberculosis. We report a case series of 14 patients with ocular tuberculosis seen in an infectious diseases department between 2006 and 2015. The diagnosis was retained on clinical data and a positive tuberculin skin test or interferon-gamma release assay. The patient's mean age was 40.7±9years. The most common clinical presentation was uveitis (11 patients and 16 eyes). An extra ocular involvement was associated in three patients. The mean duration of antitubercular therapy was 10±2.5 months. Corticosteroid therapy was associated in 11 cases. The outcome was favorable in all cases. Two patients had maintained visual sequelae. Ocular tuberculosis is a rare disease but still remains a diagnostic problem. It should be considered in case of any chronic ocular symptoms, especially in endemic countries. Early management can improve the visual prognosis. Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier SAS. All rights reserved.

    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 The purpose of this study is to describe chiropractic treatment of 14 patients who presented with signs and symptoms of temporomandibular joint dysfunction (TMD). Methods 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. Results 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. Conclusion All patients selected for this case series showed a reduction of temporomandibular dysfunction symptoms. PMID:26793040

    Benchmarking is one of the methods used in business that is applied to hospitals to improve the management of their operations. International comparison between hospitals can explain performance differences. As there is a trend towards specialization of hospitals, this study examines the benchmarking process and the success factors of benchmarking in international specialized cancer centres. Three independent international benchmarking studies on operations management in cancer centres were conducted. The first study included three comprehensive cancer centres (CCC), three chemotherapy day units (CDU) were involved in the second study and four radiotherapy departments were included in the final study. Per multiple case study a research protocol was used to structure the benchmarking process. After reviewing the multiple case studies, the resulting description was used to study the research objectives. We adapted and evaluated existing benchmarking processes through formalizing stakeholder involvement and verifying the comparability of the partners. We also devised a framework to structure the indicators to produce a coherent indicator set and better improvement suggestions. Evaluating the feasibility of benchmarking as a tool to improve hospital processes led to mixed results. Case study 1 resulted in general recommendations for the organizations involved. In case study 2, the combination of benchmarking and lean management led in one CDU to a 24% increase in bed utilization and a 12% increase in productivity. Three radiotherapy departments of case study 3, were considering implementing the recommendations.Additionally, success factors, such as a well-defined and small project scope, partner selection based on clear criteria, stakeholder involvement, simple and well-structured indicators, analysis of both the process and its results and, adapt the identified better working methods to the own setting, were found.

    Schwartz & 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 (2010) as well as a response to the six commentaries by Dell and Schwartz. In this paper, I provide a brief summary of the key points made in Schwartz and Dell (2010) 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.

    This paper proposes the classification method using Bayesian analytical method to classify the time series data in the international emissions trading market depend on the agent-based simulation and compares the case with Discrete Fourier transform analytical method. The purpose demonstrates the analytical methods mapping time series data such as market price. These analytical methods have revealed the following results: (1) the classification methods indicate the distance of mapping from the time series data, it is easier the understanding and inference than time series data; (2) these methods can analyze the uncertain time series data using the distance via agent-based simulation including stationary process and non-stationary process; and (3) Bayesian analytical method can show the 1% difference description of the emission reduction targets of agent.

    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.

    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.

    Phosphorus is an essential substance in our body, and hypophosphataemia (HP) is well-described in rickets, refeeding syndrome, diabetic ketoacidosis (DKA), and in chronic alcohol-abuse. However, to our knowledge, HP among severely-malnourished children has not been studied in detail, and information on prevalence, severity, and treatment is scarce. Currently, there are only a few published case reports of HP. This case series describes three cases of HP that presented to Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b). Our first case required mechanical ventilation for respiratory distress associated with severe hypokalaemia (K 1.1 mmol/L) and moderate hypophosphataemia (P 2.1 mg/dL). The second case presented with severe sepsis which was associated with symptomatic hypocalcaemia (Ca 1.68 mmol/L), hypokalaemia (K 1.82 mmol/L), and severe hypophosphataemia (P 0.9 mg/dL). The third case presented with pneumonia and sepsis which were complicated by hypokalaemia (K 2.05 mmol/L) and severe hypophosphataemia (P 1.1 mg/dL). Marked lethargy and severe hypotonia were associated with HP in all of these cases. Manifestations of HP are diverse and can occur in association with other electrolyte imbalances, especially among malnourished children. Malnutrition, combined with sepsis, is one of the major killers of children younger than 5 years of age, and both malnutrition and sepsis can cause HP. It is concluded that the underlying causes of morbidity, including HP, should be actively sought and treated to reduce the mortality of children aged below five years. PMID:23304916

    The case series model allows for estimation of the relative incidence of events, such as cardiovascular events, within a pre-specified time window after an exposure, such as an infection. The method requires only cases (individuals with events) and controls for all fixed/time-invariant confounders. The measurement error case series model extends the original case series model to handle imperfect data, where the timing of an infection (exposure) is not known precisely. In this work, we propose a method for power/sample size determination for the measurement error case series model. Extensive simulation studies are used to assess the accuracy of the proposed sample size formulas. We also examine the magnitude of the relative loss of power due to exposure onset measurement error, compared with the ideal situation where the time of exposure is measured precisely. To facilitate the design of case series studies, we provide publicly available web-based tools for determining power/sample size for both the measurement error case series model as well as the standard case series model.

    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.

    Vestibular schwannomas (VS) are the most common lesions of cerebellopontine angle (CPA) corresponding to 76-91 % of the cases. Usually, these lesions present typical CT and MRI findings. Non-schwannomatous tumors restricted to the internal auditory meatus (IAM) are rare and their preoperative radiological diagnosis may be difficult. This article describes nine surgically treated intrameatal non-schwannomatous lesions (NSL) and reviews the literature. In the last 16 years, a total of 471 patients with diagnosis of VS were operated on in our department. Preoperatively, 42 patients had diagnosis of intrameatal schwannomas, but surgery revealed in nine cases NSL (3 meningiomas, 3 arachnoiditis/neuritis, 1 cavernoma, 1 vascular loop, and 1 arachnoid cyst). Most frequent symptoms presented by patients with NSL were hearing loss 89 % (8/9) of patients, tinnitus 78 % (7/9), and vertigo 33 % (3/9). Almost all lesions (8/9) presented MRI findings of isointense signal in T1W with contrast enhancement. The only exception was the arachnoid cyst with intracystic bleeding, which was hyperintense in T1W that is not enhanced with contrast. This series shows an occurrence of 21.4 % of non-schwannomatous tumors in 42 cases of lesions restricted to the IAM. Whenever a solely intrameatal enhanced tumor is detected, it is necessary to think about other diagnostic possibilities rather than VS. Therapeutic management may be changed, specially if radiosurgical treatment is considered.

    The diagnosis of crusted scabies is becoming more relevant due to the increase in number of immunocompromised patients. To date, more than 200 cases have been reported in the literature. However, crusted scabies seems to be under-diagnosed because of its unusual presentations. In this case series we present history, clinical manifestations, KOH smear, and histopathological findings of a series of four patients with crusted scabies. Scaly scalp was a prominent feature of the disease in all cases. Examination of and treatment of the scalp of patients with suspected crusted scabies should not be neglected. A KOH smear from the scalp offers a simple and reliable technique for diagnosis.

    Symmetric, bilateral basal ganglia calcification is rare finding that sometimes occurs asymptomatically. Its prevalence increases with age, and the most affected site is the globus pallidus. A series of seven cases with clinical and imaging diagnosis of basal ganglia calcification, recorded during the 2012 to 2016 period at the Department of Internal Medicine of the Hospital Civil de Guadalajara "Fray Antonio Alcalde, is presented. Most common clinical presentation was with altered alertness, headache and seizures. There was one case with movement disorders; there were no cases identified with dementia or tetany. Ganglia calcification can be associated with age-related neurodegenerative changes, but it can be an initial manifestation of a variety of systemic pathologies, including disorders of the calcium metabolism, intoxication by different agents, and autoimmune and genetic diseases. Correlation of typical imaging findings with clinical manifestations and laboratory results should be established to reach a definitive judgment. Copyright: © 2018 SecretarÍa de Salud.

    To assess the effectiveness and feasibility of behavioral sleep intervention for medicated children with ADHD. Six medicated children (five boys, one girl; aged 6-12 years) with ADHD participated in a 4-week sleep intervention program. The main behavioral strategies used were Faded Bedtime With Response Cost (FBRC) and positive reinforcement. Within a case-series design, objective measure (Sleep Disturbance Scale for Children [SDSC]) and subjective measure (sleep diaries) were used to record changes in children's sleep. For all six children, significant decrease was found in the severity of children's sleep problems (based on SDSC data). Bedtime resistance and mean sleep onset latency were reduced following the 4-week intervention program according to sleep diaries data. Gains were generally maintained at the follow-up. Parents perceived the intervention as being helpful. Based on the initial data, this intervention shows promise as an effective and feasible treatment.

    Asperger syndrome (AS) is an autism spectrum disorder with a high rate of psychiatric comorbidity. We describe the clinical profile and psychiatric comorbidity in a series of affected individuals referred to an Indian general hospital psychiatry setting. Gilliam Asperger's disorder scale was used to evaluate the clinical characteristics while Mini-International Neuropsychiatric Interview (MINI)-KID and MINI-PLUS were used to assess psychiatric comorbidity. The profile of subjects with AS in our case-series appears similar to that published elsewhere with high rates of psychiatric comorbidity. Mental health professionals should evaluate for psychiatric comorbidity in individuals with autism spectrum disorders. PMID:25969609

    Background A new class of hallucinogens called NBOMes has emerged. This class includes analogues 25I-NBOMe, 25C-NBOMe and 25B-NBOMe. Case reports and judicial seizures indicate that 25I-NBOMe and 25C-NBOMe are more prevalently abused. There have been a few confirmed reports of 25B-NBOMe use or toxicity. Report Observational case series. This report describes a series of 10 patients who suffered adverse effects from 25B-NBOMe. Hallucinations and violent agitation predominate along with serotonergic/stimulant signs such as mydriasis, tachycardia, hypertension and hyperthermia. The majority (7/10) required sedation with benzodiazepines. Analytical method 25B-NBOMe concentrations in plasma and urine were quantified in all patients using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Peak plasma levels were measured between 0.7-10.1 ng/ml. Discussion The NBOMes are desired by users because of their hallucinogenic and stimulant effects. They are often sold as LSD or synthetic LSD. Reported cases of 25B- NBOMe toxicity are reviewed and compared to our series. Seizures and one pharmacological death have been described but neither were observed in our series. Based on our experience with cases of mild to moderate toxicity, we suggest that management should be supportive and focused on preventing further (self) harm. High doses of benzodiazepines may be required to control agitation. Patients who develop significant hyperthermia need to be actively managed. Conclusions Effects from 25B-NBOMe in our series were similar to previous individual case reports. The clinical features were also similar to effects from other analogues in the class (25I-NBOMe, 25C-NBOMe). Violent agitation frequently present along with signs of serotonergic stimulation. Hyperthermia, rhabdomyolysis and kidney injury were also observed.

  8. Clopidogrel (Plavix) desensitization: a case series.

    Clopidogrel (Plavix) is a thiopyridine that inhibits the ADP-dependent pathway for platelet activation and has been shown in numerous trials to be effective for a wide variety of patients with cardiovascular disease, particularly those who have undergone coronary stent implantation and who present with acute coronary syndromes. Allergic rashes are one of the common side effects of clopidogrel, which leads to its discontinuation. Type I (Gell and Combs classification) allergic reactions to drugs may be amenable to drug desensitization, allowing safe and prolonged use of the drug. This case series describes a protocol for clopidogrel desensitization over an 8-hr period using 15 doubling doses of clopidogrel given by mouth to achieve a maintenance dose of 75 mg a day. This case series suggests that patients who have had type I drug allergy to clopidogrel may be rapidly desensitized using this protocol. Further studies enrolling a larger number of patients are indicated to confirm the safety and efficacy of this regimen.

    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).

  11. On the equivalence of case-crossover and time series methods in environmental epidemiology.

    2007-04-01

    The case-crossover design was introduced in epidemiology 15 years ago as a method for studying the effects of a risk factor on a health event using only cases. The idea is to compare a case's exposure immediately prior to or during the case-defining event with that same person's exposure at otherwise similar "reference" times. An alternative approach to the analysis of daily exposure and case-only data is time series analysis. Here, log-linear regression models express the expected total number of events on each day as a function of the exposure level and potential confounding variables. In time series analyses of air pollution, smooth functions of time and weather are the main confounders. Time series and case-crossover methods are often viewed as competing methods. In this paper, we show that case-crossover using conditional logistic regression is a special case of time series analysis when there is a common exposure such as in air pollution studies. This equivalence provides computational convenience for case-crossover analyses and a better understanding of time series models. Time series log-linear regression accounts for overdispersion of the Poisson variance, while case-crossover analyses typically do not. This equivalence also permits model checking for case-crossover data using standard log-linear model diagnostics.

    During 2004, a case series of decompression sickness (DCS) meeting the definition of epidemic DCS was observed in the Shaw AFB Physiological Training Program. There were 10 cases of chamber-induced altitude DCS observed. Internal and external investigations focused on time, place, person, and environment. No temporal trend was observed. Chamber, masks, regulators, crew positions, and oxygen sources revealed no defects. Among the cases, mean age was 27 yr. Peak altitude in four cases was 35,000 ft and in the other six cases was 25,000 ft. Six had joint pain, one skin symptoms, and three neurological findings. Four were treated with 100% ground-level oxygen and six with hyperbaric oxygen. Four were students and six were inside observers (IO). Four were women and six men. In the IO, where four of the six were women, no gender effect was seen. Examining the IO monthly exposure load (exposures per month) against DCS suggested a dose-response relationship. This relationship held true when 4 yr of Shaw AFB IO data was studied. Indeed, Poisson regression analysis demonstrated a statistically significant 2.1-fold rise in DCS risk with each monthly exposure. Consequently, the number of exposures per month may need to be considered when devising IO schedules.

    The purpose of this study is to demonstrate the importance of knowledge of the internal anatomy of root canals for the success of endodontic treatment. Lack of knowledge of anatomic variations and their characteristics in different teeth has been pointed out as one of the main cause of endodontic therapy failure. Dental operating microscope plays a key role in the identification of canal and success of endodontic treatment. This case series describes the endodontic treatment of mandibular first molars with extra root canals, evaluate the occurrence of this extra canal, and discuss the importance of their identification and treatment.

    Case-crossover designs are widely used to study short-term exposure effects on the risk of acute adverse health events. While the frequentist literature on this topic is vast, there is no Bayesian work in this general area. The contribution of this paper is twofold. First, the paper establishes Bayesian equivalence results that require characterization of the set of priors under which the posterior distributions of the risk ratio parameters based on a case-crossover and time-series analysis are identical. Second, the paper studies inferential issues under case-crossover designs in a Bayesian framework. Traditionally, a conditional logistic regression is used for inference on risk-ratio parameters in case-crossover studies. We consider instead a more general full likelihood-based approach which makes less restrictive assumptions on the risk functions. Formulation of a full likelihood leads to growth in the number of parameters proportional to the sample size. We propose a semi-parametric Bayesian approach using a Dirichlet process prior to handle the random nuisance parameters that appear in a full likelihood formulation. We carry out a simulation study to compare the Bayesian methods based on full and conditional likelihood with the standard frequentist approaches for case-crossover and time-series analysis. The proposed methods are illustrated through the Detroit Asthma Morbidity, Air Quality and Traffic study, which examines the association between acute asthma risk and ambient air pollutant concentrations. © 2013, The International Biometric Society.

    The attention of international agencies and scientific community on mobbing (bullying) and work-related stress is increasing. However, research on gender differences and etiologic agents is still limited. This study describes the gender differences found in victims of mobbing and work-related stress in an Italian case series. Between 2001 and 2009, at the Occupational Medicine Unit of our Institution we examined 345 outpatients (197 women and 148 men) for suspected psychopathological work-related problems. After interdisciplinary diagnostic evaluation, the diagnosis of "mobbing syndrome" was formulated, according to international criteria (ICD-I0 and DSM-IV), in a minority of cases: 35 subjects. In the other workers, we found pre-existing psychiatric conditions (not related to work), or altered relationships dynamics with the colleagues. Significant gender differences emerged among people with "mobbing syndrome": there was a high prevalence of women (65%), with medium to high level of education; the most affected age group was between 34 and 45 years; several occupations were involved, with a clear preponderance of office workers. Women are mostly harassed for personal aspects related to emotional and relational factors; men for the content of their work. The knowledge of the phenomenon is an essential prerogative to contrast mobbing; this can be realized, at a preventive level, only through effective information and training for workers and employers, who have the legal obligation to preserve the integrity of the mental and physical status of their employees during the work.

  17. Successful use of right unilateral ECT for catatonia: a case series.

    Catatonia is a neuropsychiatric syndrome involving motor signs in association with disorders of mood, behavior, or thought. Bitemporal electrode placement electroconvulsive therapy (ECT) is a proven effective treatment for catatonia, and this mode of ECT delivery is the preferred method of treatment in this condition. Studies in major depressive disorder have demonstrated that suprathreshold, nondominant (right) hemisphere, unilateral electrode placement ECT has fewer adverse effects, especially cognitive adverse effects, than bitemporal ECT. This case series describes the use of right unilateral (RUL) ECT in 5 patients with catatonia. Before ECT, all 5 patients in this series initially failed therapy with benzodiazepines and psychotropic medications. Each catatonic patient received a series of 8 to 12 RUL ECT in an every-other-day series. After ECT, 4 of the 5 patients had a full recovery from catatonia. One patient achieved only partial response to RUL ECT, and no additional benefit was obtained with bitemporal ECT. All patients in this case series tolerated RUL ECT without major adverse effects. This case series illustrates successful use of RUL ECT in patients with catatonia and adds to the early literature demonstrating its effective use in treating this complex condition.

    Cervical cancer is one of the most frequent malignancies in women worldwide and is unfortunately diagnosed in advanced stages of the disease. Whenever local invasion is present, neoadjuvant therapy might be needed in order to limit the degree of local invasion. However, in certain cases local invasion persists even after completing the neoadjuvant radiochemotherapy; in these patients more extensive resections might be needed in order to achieve a radical resection. We present a case series of eight patients in whom segmental ureteral or uretero-vesical resections were performed as part of the radical resections for locally advanced cervical tumors. The continuity of the urinary tract was re-established by performing ureteral reimplantation via uretero-neocystostomy, augmentation cystoplasties with ureteral reimplantations. In a single case ureteral reimplantation was not feasible, a definitive cutaneous ureterostomy being performed. The postoperative course was uneventful in seven cases while in a single case urinary leak occurred, necessitating the exteriorization of the ureter in terminal cutaneous ureterostomy. Ureteral resections can be safely performed in patients with locally advanced cervical cancer. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    Osteonecrosis of the jaw (ONJ) is a potentially severe adverse effect of various medications (bisphosphonates, anti-resorptive, and anti-angiogenic drugs). ONJ pathogenesis is still unclear although some risk factors have been recognized. Of these, rheumatoid arthritis (RA) has been hypothesized as a potential risk factor for developing ONJ. This observational study will describe a multicenter case series of patients affected with RA and ONJ, and it will attempt to evaluate the association between features of ONJ and pharmacological, systemic, and site variables. Demographic, pharmacological, and clinical data from 18 RA patients with ONJ were collected and registered from three Italian centers (i.e., Palermo, Verona, and Padua) from 2004 to 2013. Sixteen (88.9%) patients were in therapy for RA: 9 of 18 (50.0%) with systemic steroids, 3 of 18 (16.7%) with methotrexate, and 4 of 18 (22.2%) with both medications. Two patients were not receiving treatment for RA. All patients took NBPs for secondary osteoporosis (average NBP duration of 69 months, range: 20-130): Fifteen (83.3%) patients were treated with single NBPs, while three (16.7%) with different molecules; one patient was also treated with denosumab. Mandible was affected more frequently (66.7%) than maxilla (33.3%); one patient presented multiple ONJ events. This is the first multicenter case series in the international literature regarding our topic. Focusing on our data, it could be hypothesized that patients with RA may be more susceptible to ONJ than the majority of osteometabolic patients. In our opinion, it could be important to monitor also denosumab or other biological drug side effects. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Case series are an important and common study type. No guideline exists for reporting case series and there is evidence of key data being missed from such reports. The first step in the process of developing a methodologically sound reporting guideline is a systematic review of literature relevant to the reporting deficiencies of case series. A systematic review of methodological and reporting quality in surgical case series was performed. The electronic search strategy was developed by an information specialist and included MEDLINE, Embase, Cochrane Methods Register, Science Citation Index and Conference Proceedings Citation index, from the start of indexing to 5 November 2014. Independent screening, eligibility assessments and data extraction were performed. Included articles were then analysed for five areas of deficiency: failure to use standardized definitions, missing or selective data (including the omission of whole cases or important variables), transparency or incomplete reporting, whether alternative study designs were considered, and other issues. Database searching identified 2205 records. Through the process of screening and eligibility assessments, 92 articles met inclusion criteria. Frequencies of methodological and reporting issues identified were: failure to use standardized definitions (57 per cent), missing or selective data (66 per cent), transparency or incomplete reporting (70 per cent), whether alternative study designs were considered (11 per cent) and other issues (52 per cent). The methodological and reporting quality of surgical case series needs improvement. The data indicate that evidence-based guidelines for the conduct and reporting of case series may be useful. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

    The current prescription of clozapine in psychotic women of reproductive age makes it crucial to understand its pharmacokinetics during pregnancy and lactation as well as its risk profile for neonatal outcome. The aim of this case series was to provide new evidence on the pharmacokinetic features of clozapine that determine its passage through the placenta and amniotic fluid, as well as the neonatal clozapine elimination half-life (t1/2). This case series demonstrates for the first time that clozapine might show partial placental passage similar to other atypical antipsychotics. Clozapine levels decreased during the first few days in nursing infants. The half-life of clozapine in neonates was slightly higher than previously estimated. Clozapine use in pregnancy may be associated with diabetes mellitus, especially if there is a family history of this disease. Although no acute toxicological effects were observed in the intrauterine exposed newborn, close follow-up of pregnancy is recommended. However, these results must be taken with caution being a case series with small sample size.

    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.

    In the literature, vitamin B 6 has been linked to the development of polyneuropathy. Most often, these complaints were seen when taking high doses of vitamin B 6 for a long time. Evidence as to whether a lower dosage range of vitamin B 6 (< 50 mg/day) can also induce neuropathy is scarce. We aim to comprehensively describe the cases of neuropathy associated with vitamin B 6 received by the Netherlands Pharmacovigilance Centre Lareb and to assess the case series concerning the use of vitamin B 6 and neuropathic complaints. We describe the number and nature of the reported cases, including suspect product, dosage, duration of use, and vitamin B 6 serum levels. In addition, we describe the causality for the individual cases (Naranjo Probability Scale) and for the entire case series (Bradford Hill criteria). In total, 90 reports on products containing vitamin B 6 included at least one adverse drug reaction in the standardized Medical Dictionary for Regulatory Activities (MedDRA ® ) query (SMQ; broad) 'peripheral neuropathy'. The amount of vitamin B 6 in the products varied between 1.4 and 100 mg per tablet. The serum vitamin B 6 level was known in 36 cases (88-4338 nmol/l), and the mean serum vitamin B 6 level was 907 nmol/l. However, no statistical correlation between dosage and vitamin B 6 blood levels was found. Causality assessment of the case series of 90 reports to Lareb shows it is plausible for the vitamin B 6 supplements to have caused complaints such as neuropathies. This is especially the case with higher dosages and prolonged use, but dosages < 50 mg/day also cannot be excluded.

  8. An approach to checking case-crossover analyses based on equivalence with time-series methods.

    The case-crossover design has been increasingly applied to epidemiologic investigations of acute adverse health effects associated with ambient air pollution. The correspondence of the design to that of matched case-control studies makes it inferentially appealing for epidemiologic studies. Case-crossover analyses generally use conditional logistic regression modeling. This technique is equivalent to time-series log-linear regression models when there is a common exposure across individuals, as in air pollution studies. Previous methods for obtaining unbiased estimates for case-crossover analyses have assumed that time-varying risk factors are constant within reference windows. In this paper, we rely on the connection between case-crossover and time-series methods to illustrate model-checking procedures from log-linear model diagnostics for time-stratified case-crossover analyses. Additionally, we compare the relative performance of the time-stratified case-crossover approach to time-series methods under 3 simulated scenarios representing different temporal patterns of daily mortality associated with air pollution in Chicago, Illinois, during 1995 and 1996. Whenever a model-be it time-series or case-crossover-fails to account appropriately for fluctuations in time that confound the exposure, the effect estimate will be biased. It is therefore important to perform model-checking in time-stratified case-crossover analyses rather than assume the estimator is unbiased.

    Hidradenitis suppurativa (HS) is an overlooked but common disease severely affecting both genders. HS is generally perceived as difficult to treat and although a number of treatments are available, the need for more effective treatment is apparent. Cyclosporine A (CsA) has been suggested as an effective treatment in four smaller case series. It was therefore decided to review a larger series of cases, reporting all outcomes in order to provide a less biased base for evaluating the potential of CsA for use in HS. An exploratory retrospective review of case notes was performed at three departments of dermatology with a special interest in HS, where HS had been treated with CsA in the period 2009-2012. In total, 18 HS patients treated with CsA were identified and analysed and 50% reported some benefit. All patients had previously been treated with multiple various other modalities. This is an exploratory retrospective review with a limited number of patients. This retrospective review found some effect of CsA in the recalcitrant cases studied, mainly reported as "slight improvement". This may be due to a number of factors which may have overestimated (e.g., concommitant therapy) or underestimated (e.g., case selection of recalcitrant cases) the effect, and indicates the need for prospective evaluation of the claims. The present data provide a basis for power calculations in future studies investigating the potential for treating HS with CsA in a randomised controlled trial.

    Fifth metatarsal tuberosity avulsion fractures are common. Despite good outcomes with nonoperative treatment, acute fractures with displacement, intra-articular involvement, comminution, or painful nonunion have been reported to benefit from early open reduction and internal fixation, especially in athletes. No consensus has been reached regarding the best surgical fixation technique. We present a case series of 4 patients with displaced fifth metatarsal tuberosity avulsion fractures and an innovative technique of fixation for the tuberosity avulsion fractures using a suture anchor.

    Left cardiac sympathetic denervation (LCSD) is a surgical procedure that has been shown to have an antiarrhythmic and antifibrillatory effect. Evidence indicating its antiarrhythmic effect has been available for over 100 years. It involves the removal of the lower half of the stellate ganglion and T2-T4 of the sympathetic ganglia and is carried out as either a unilateral or bilateral procedure. With advancements in thoracic surgery, it can be safely performed via a minimally invasive Video-Assisted Thoracoscopic Surgery (VATS) approach resulting in significantly less morbidity and a shortened inpatient stay. LCSD provides a valuable treatment option for patients with life-threatening channelopathies and cardiomyopathies. This case series reports the preliminary paediatric and adult experience in the Republic of Ireland with LCSD and describes five cases recently treated in addition to an outline of the operative procedure employed. Of the five cases included, two were paediatric cases and three were adult cases. One of the paediatric patients had a diagnosis of the rare catecholaminergic polymorphic ventricular tachycardia (CPVT) and the other a diagnosis of long-QT syndrome. Both paediatric patients experienced excellent outcomes. Of the three adult patients, two benefitted greatly and remain well at follow-up (one inappropriate sinus tachycardia and one CPVT). One patient with idiopathic ventricular fibrillation unfortunately passed away from intractable VF despite all attempts at resuscitation. In this case series, we highlight that LCSD provides a critical adjunct to existing medical therapies and should be considered for all patients with life-threatening refractory arrhythmias especially those patients on maximal medical therapy.

    There are few data relating to sirolimus overdose in the medical literature. Our objectives were to describe all cases of overdose with sirolimus reported to Swiss, German and Austrian Poisons Centres between 2002-2013. An observational case-series analysis was performed to determine circumstances, magnitude, management and outcome of sirolimus overdose. Five cases of acute sirolimus overdose were reported--three in young children and two in adults. Four were accidental and one was with suicidal intent. Two patients developed symptoms probably related to sirolimus overdose: mild elevation of alkaline phosphatase, fever and gastroenteritis in a 2.5-year-old male who ingested 3 mg, and mild changes in total cholesterol in an 18-year-old female after ingestion of 103 mg. None of these events were life-threatening. Serial blood concentration measurements were performed starting 24 h after ingestion of 103 mg in a single case, and these followed a similar pharmacokinetic time-course to measurements taken after dosing in the therapeutic range. Acute sirolimus overdose occurred accidentally in the majority of cases. Even large overdoses appeared to be well-tolerated, however children might be at greater risk of developing complications. Further study of sirolimus overdose is needed.

    Asymmetric hypertrophy of the labia minora is a variant of normal anatomy that has not been described in the pediatric dermatology literature. Although often asymptomatic, in some cases, it can cause functional, emotional, and psychological problems. We report the clinical characteristics and outcomes of four children who presented with unilateral labium minus hypertrophy. This case series aims to establish awareness of this condition among pediatric dermatologists and provide recommendations regarding management. © 2018 Wiley Periodicals, Inc.

  19. Urogenital fistula in the UK: a personal case series managed over 25 years.

    Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Whilst several very large series of obstetric fistulae from the developing world have been published, data on fistulae as seen in the developed world are relatively few. Most fistulae in the UK are known to follow hysterectomy, and several risk factors are recognised. We have confirmed the common association with pelvic surgery, and in particular hysterectomy, but also show the broad range of other associated operations, including so called 'minimally invasive' procedures. High rates of both anatomical fistula closure and continence are shown, when a consistent approach to assessment, selection of surgical procedure, and postoperative care are applied. Successful closure is seen more often in women who have not undergone previous attempts at repair before referral, and as a result a pattern of surpra-regional management is proposed. Whilst overall the number of urogenital fistulae seen in the UK appears to be decreasing, there is a suggestion from these data that the rate of fistula formation following hysterectomy may be increasing; we are currently investigating this possibility through detailed interrogation of a national dataset. To review demography, aetiology, surgery and outcomes of women with urogenital fistula seen in one unit over the last 25 years; to provide data for comparison with a parallel study based on Hospital Episode Statistics. This is a prospective case series from a tertiary urogynaecology centre providing a de facto supra-regional fistula service. The women included had confirmed urogenital fistula referred between January 1986 and December 2010. Index cases were identified from a surgical database; data were entered prospectively and updated as appropriate; statistics are largely descriptive. The primary outcome is the patient's report of absence of urinary leakage. Secondary outcomes include operative or postoperative

    This paper describes the new global long-term International Satellite Cloud Climatology Project (ISCCP) H-series climate data record (CDR). The H-series data contain a suite of level 2 and 3 products for monitoring the distribution and variation of cloud and surface properties to better understand the effects of clouds on climate, the radiation budget, and the global hydrologic cycle. This product is currently available for public use and is derived from both geostationary and polar-orbiting satellite imaging radiometers with common visible and infrared (IR) channels. The H-series data currently span July 1983 to December 2009 with plans for continued production to extend the record to the present with regular updates. The H-series data are the longest combined geostationary and polar orbiter satellite-based CDR of cloud properties. Access to the data is provided in network common data form (netCDF) and archived by NOAA's National Centers for Environmental Information (NCEI) under the satellite Climate Data Record Program (https://doi.org/10.7289/V5QZ281S). The basic characteristics, history, and evolution of the dataset are presented herein with particular emphasis on and discussion of product changes between the H-series and the widely used predecessor D-series product which also spans from July 1983 through December 2009. Key refinements included in the ISCCP H-series CDR are based on improved quality control measures, modified ancillary inputs, higher spatial resolution input and output products, calibration refinements, and updated documentation and metadata to bring the H-series product into compliance with existing standards for climate data records.

    The aim of our retrospective study is to report a case series of ocular infections caused by a rare fungus, Scedosporium apiospermum, in a South Indian population. Thirteen cases of culture-positive S. apiospermum infections diagnosed between January 2011 and March 2016 were included in this study. The parameters evaluated were predisposing factors, treatment and final clinical outcome. The most common mode of presentation was keratitis (84.6%) followed by sclerokeratitis (15.3%). The predisposing factors involved were unspecified foreign body injury (30.7%), organic matter injury (15.3%), uncontrolled diabetes (7.6%), and recent manual small-incision cataract surgery (7.6%). Five cases (38.46%) had no predisposing factor. Of the 11 keratitis cases, nine (69.2%) responded well to combination medical therapy while one case (7.6%) required therapeutic keratoplasty. One case was lost to follow-up. Both cases which presented with sclerokeratitis showed no response to medico-surgical treatment progressing to panophthalmitis and evisceration. PMID:29283143

    2018-05-01

    We undertook an analysis of all the reports to the New Zealand Centre for Adverse Reactions Monitoring of a roxithromycin/warfarin interaction after two recent reports described intense rapid warfarin potentiation. The interaction was first published in 1995. Cytochrome P450 3A4 inhibition has been the proposed mechanism but has limited biologic plausibility. There are suggestions that the clinical significance of the interaction may be increased by severe illness, polypharmacy, renal dysfunction, older age and increased warfarin sensitivity. To investigate the potentiating effect of warfarin on roxithromycin in this New Zealand case series, the reports were reviewed to identify patients at risk, compare the reporting pattern with published Australian data and evaluate the appropriateness of current prescribing advice. Thirty patient reports were identified. The age range was 23-88 years, mean 66.8, median 73.0 (standard deviation 17.7) and the international normalised ratios after roxithromycin commencement ranged from 3.6 to 16.7 (mean 7.6, median 7.6, standard deviation 3.6). For eight patients with measurements on day 3, international normalised ratios were 4.3-16.7 (mean 10.4, median 8.8, standard deviation 4.4). Four patients had serious haemorrhage. Indications for roxithromycin were a range of respiratory tract infections. Anticoagulation was stable for most patients prior to acute infection. Serious infection occurred in 54.5% (12 of 22 patients with information). Polypharmacy (five or more medicines daily) was used by 36.7% of patients long term, increasing acutely to 83.3%, including additional potentially interacting medicines. Warfarin daily dose (1.5-13.0 mg, mean 4.4, median 4.0, standard deviation 2.2) was moderate to low. Pre-roxithromycin international normalised ratio values ranged from 1.4 to 3.7, mean and median 2.5, standard deviation 0.5. A high proportion of interactions were observed between warfarin and roxithromycin compared with other

    Gallbladder perforation is a serious complication of acute cholecystitis. Its management has evolved considerably since its classification by Niemeier in 1934. This review summarises the evidence surrounding the natural progression of this condition and potential problems with Niemeier's classification, and proposes a management algorithm for the more complex type II perforation. Data from a retrospective case series and a systematic review were combined. The case series included all patients with gallbladder perforations from 2004 to 2008 at a British teaching hospital. The systematic review searched for gallbladder perforation using the MEDLINE, Embase, Web of Science and Cochrane Library (2011 Issue 4) databases, as well as recent conference abstracts. The outcome data were analysed using SPSS version 15. No adjustments were made for multiple testing. 198 patients (including 19 patients from the present series) with a mean age of 62.1+/-9.7 years and male gender proportion of 55.4% (range 33.3-76.7%) were included. The most common gallbladder perforations were type II (median 46.2%, range 7.4-83.3%), followed by type I (median 40.6%, range 16.7-70.0%) and type III (median 10.1%, range 0-48.1%). Perforation was associated with cholelithiasis in 86.6% (range 78.9-90.6%) of patients, and the overall median mortality rate was 10.8% (range 0-12.5%). Male gender was weakly associated with mortality (p = 0.089) but age (p = 0.877) and cholelithiasis (p = 0.425) were not. Mortality did not vary significantly with perforation type. Gallbladder perforation should be reported according to the original Neimeier's classification to avoid heterogeneity in data (e.g. varying rates of perforation types). The algorithm proposed in this study aims to guide the management of complex type II gallbladder perforations to minimise subsequent morbidity and mortality. Copyright © 2012 Surgical Associates Ltd.

    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.

    Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is a debilitating neuropathic pain condition. A small portion of patients do not respond to any currently available treatment modalities. These patients, often young women, might benefit from targeted spinal cord stimulation of the dorsal root ganglion (DRG). This retrospective case series describes five ACNES patients who were referred from a Dutch dedicated tertiary referral center to collaborating sites with extensive experience in DRG stimulation to be implanted with a DRG Axium System (St. Jude/Abbott, IL, USA) in the period of 2013-2016. Numeric pain rating scores at routine 6- and 12-month follow-up visits were analyzed. Three patients experienced >50% pain reduction at 12 months follow-up. Four patients experienced device-related complications, such as lead dislocation, lead breakage, pain at the battery site, and overstimulation. This case series suggests DRG spinal cord stimulation can be safe and effective for some patients with persistent pain due to ACNES. © 2017 International Neuromodulation Society.

    In keeping with international trends, lung cancer incidence and mortality are increasing among the Irish population with many patients presenting with advanced disease that excludes the potential for curative management. Consequently palliative treatment options for this patient group are being increasingly explored with various degrees of success. Endobronchial stenosis represents a particularly challenging area of management among these patients and a number of techniques have been described without the identification of a single gold standard. We report our experience of the first time use of endobronchial cryotherapy in Ireland with reference to a case series, including an example of its use in the management of benign disease, in order to support patients with borderline lung function and enable definitive palliative treatment.

  10. (Meth)Acrylate Occupational Contact Dermatitis in Nail Salon Workers: A Case Series.

    PubMed

    DeKoven, Samuel; DeKoven, Joel; Holness, D Linn

    Recently, many cases of acrylate-associated allergic contact dermatitis have appeared among nail salon workers. Common acrylate-containing products in nail salons include traditional nail polish, ultraviolet-cured shellac nail polish, ultraviolet-cured gel nails, and press-on acrylic nails. Nail salon technicians seen in the occupational medicine clinic in 2015 and 2016 were identified, and their patch test results and clinical features were summarized. Patch testing was done with the Chemotechnique (Meth)Acrylate nail series, and either the North American Standard series or the North American Contact Dermatitis Group screening series. Six patients were identified, all women, ages 38 to 58. Common presentations included erythematous dermatitis of the dorsa of the hands, palms, and forearms and fissures on the fingertips. Less common sites of eruptions included the periorbital region, cheeks, posterior ears, neck, sacral area, lateral thighs, and dorsa of the feet. All patients reacted to hydroxyethyl methacrylate, and 5 patients reacted to ethyl acrylate. Each patient also reacted to (meth)acrylates that are not found on either standard series, including ethyleneglycol dimethacrylate, 2-hydroxypropyl methacrylate, and 2-hydroxyethyl acrylate. The authors report 6 cases of allergic contact dermatitis to acrylates in nail technicians seen over the past year, representing a new trend in their clinic. These cases are reflective of a growing trend of nail technicians with allergic contact dermatitis associated with occupational (meth)acrylate exposure. Efforts to improve prevention are needed.

    Honey poisoning cases occur in southwestern China. In this case series, we attempted to determine the symptoms and causes of honey poisoning from 2007 to 2012 in southwestern China. We also conducted a quantitative melissopalynological analysis of honey samples. During the study period, 31 honey poisoning cases occurred in the study location, all during July to August. All the cases occurred after consuming at least 100 grams of honey. The most frequent symptoms were nausea and vomiting (100%), abdominal pain (90.3%), diarrhea (74.2%), palpitations (61.3%), dizziness (54.8%), chest congestion (48.4%) and dyspnea (48.4%). Severe cases developed oliguria/anuria, twitch, hematuria, ecchymosis or hematochezia. The median time from ingestion to onset of symptoms was 29 hours. Eight patients died (mortality rate: 25.8%). The pollen of Tripterygium hypoglaucum (a plant with poisonous nectar and pollen) was detected in 22 of 29 honey samples examined (75.9%). The results of pollen analysis were consistent with the clinical findings of previous cases. T. hypoglaucum appears to be the cause of honey poisoning in southwestern China. Honey poisoning should be included in the differential diagnosis of patients who consume honey in this region and develop symptoms of food poisoning.

    The extent to which cognitive-behavioral therapy (CBT) is helpful in treating individuals with bulimic symptoms who do not meet full criteria for bulimia nervosa is unclear. The purpose of this investigation was to examine the potential efficacy of CBT for eating disorder individuals with bulimic symptoms who do not meet full criteria for bulimia nervosa. Twelve participants with subthreshold bulimia nervosa were treated in a case series with 20 sessions of CBT. Ten of the 12 participants (83.3%) completed treatment. Intent-to-treat abstinent percentages were 75.0% for objectively large episodes of binge eating (OBEs), 33.3% for subjectively large episodes of binge eating (SBEs), and 50% for purging at end of treatment. At one year follow-up, 66.7% were abstinent for OBEs, 41.7% for SBEs, and 50.0% for purging. The majority also reported improvements in associated symptoms. This case series provides support for the use of CBT with individuals with subthreshold bulimia nervosa.

    Introduction: This study reports a case series of orthoptic treatment (OT) for convergence insufficiency (CI) in individuals with Parkinson's disease (PD). Method: We are reporting two cases of individuals with PD who completed OT for CI. Both had a confirmed diagnosis of CI, accompanied by CI-type symptomatology. They each underwent an OT program consisting of three office-based visits and 8 weeks of home-based exercises. Treatment outcome was based on the changes measured pre- versus post-OT on the near point of convergence, positive fusional vergences, and symptomatology score. Results: The two participants successfully completed therapy, gained ability to converge, had fewer symptoms, and were satisfied with the OT-induced changes they felt in their day-to-day lives. Conclusion: This case series show that OT for CI in PD is possible. Further research is required as these results demonstrate that OT has the potential to improve symptomatic CI in these patients. In the meantime, the positive results obtained in these two cases should encourage clinicians to consider OT (a therapy with no/minimal risk) for CI in patients with PD whose quality of life is affected by this binocular dysfunction.

    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.

    The objective of this study is to describe a case-series of potassium aluminium tetrafluoride (KAlF(4))-induced occupational asthma (OA) and/or occupational rhinitis (OR). The study involves five patients from a heat-exchanger production line who were examined (including specific inhalation challenge tests) for suspected OA and/or OR caused by a flux containing almost 100% KAlF(4) - with fluorides' workplace air concentrations ranging between 1.7 and 2.8 mg/m(3). No subject had a previous history of asthma. All five patients had a positive specific challenge test (three patients were diagnosed with OA alone, one with OR and one with both OR and OA). At the follow-up visit, after three years on average, all patients needed permanent corticosteroid therapy (four topical, one oral). After elimination from the exposure, only one of the observed subjects gave an indication of an improvement, two subjects stabilized and two worsened. Our case series focuses on the correlation between patients' exposure to fluorides in air-conditioner production and the subsequent occurrence of OR/OA. Currently, it is uncertain whether these OR/OA were caused by hypersensitivity or irritation.

    The Gorlin-Goltz syndrome (GGS) is also known as nevoid basal cell carcinoma syndrome. It is characterized by multiple keratocystic odontogenic tumors (KCOTs) in the jaw, multiple basal cell nevi carcinomas and skeletal abnormities. The syndrome may be diagnosed early by a dentist during the routine radiographic exams in the first decade of life, since the KCOTs are usually one of the first manifestations of the syndrome. This article reports the series of 3 cases, emphasizing its clinical and radiographic manifestations of GGS.

    2017-12-01

    The orthopedic literature has shown an increasing incidence of prosthetic joint infections (PJIs) associated with Propionibacterium acnes (P acnes). These infections present serious diagnostic and management challenges to the treating surgeons. In this review, the authors report on cases of P acnes-related temporomandibular joint (TMJ) PJIs that have been diagnosed and treated at their institution. After approval by the institutional review board, information was obtained through a retrospective chart review. Records were retrieved from clinic visits from January 1, 2010 through January 1, 2015 using appropriate International Classification of Diseases, Ninth Revision codes. Data extracted included patient demographics, prostheses details, prosthetic infection history, interventions, diagnostic procedures, and culture processing methods. Of the 7 patients who met the search criteria, 4 (1 with bilateral prostheses) had cultures positive for P acnes. For the 5 TMJ PJIs with cultures positive for P acnes, tissue cultures were obtained in the operating room and processed using mass spectrometry. Symptoms identified in these 4 patients were vague and included pain and intermittent swelling; clinical and radiographic findings were nonspecific. Treatment regimens included oral and parenteral antibiotics and operative interventions. In this case series, the authors report on the management of 4 cases of P acnes-related TMJ PJI. When patients with TMJ prostheses report vague symptoms of swelling and pain that do not fit the typical infection scenario, the surgeon should consider P acnes as a source of infection. Additional case series and retrospective reviews will be necessary before developing prospective trials that could aid in the prevention and management of this infection.

    2014-01-01

    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

    Developmental defects involving color alteration of enamel frequently compromise the esthetic appearance of the tooth. The resin infiltration technique represents an alternative treatment for color masking of these lesions and uniformization of tooth color. This technique is considered relatively simple and microinvasive, since only a minimal portion of enamel is removed. This article illustrates the color-masking effect with resin infiltration of fluorosis and traumatic hypomineralization lesions with a case series. The final esthetic outcomes demonstrated the ability of the resin infiltrant to mask the color of white developmental defect lesions, resulting in satisfactory clinical esthetic improvements. However, in more severe cases, the color-masking effect was not complete.

    Phenobarbital-responsive sialadenosis (PRS) is a rare idiopathic disease in dogs. Vomiting, retching, and gulping with bilateral enlargement of the submandibular salivary glands are the more frequent clinical signs. A thorough diagnostic examination must be performed to rule out the most important systemic etiologies involved with chronic vomiting, as there is no specific test to diagnose PRS. Diagnosis is confirmed clinically by a rapid and dramatic improvement of clinical signs after instauration of phenobarbital treatment. The aim of this article is to describe the clinical presentation, diagnostic findings, and outcome of a case series of 4 dogs with presumptive PRS. Copyright © 2015 Elsevier Inc.

    Introduction: Solitary fibrous tumor (SFT) is rarely diagnosed in clinical practice. Since its initial descriptions in the central nervous system (CNS) and the orbits, very few case reports and small case series have expanded their clinical and pathological characterization. We sought to describe a cases series of SFT from a single laboratory of neuropathology belonging to a tertiary university hospital. Methods: Retrospective clinical and histopathological description of eight cases of CNS and orbital SFT diagnosed over a 21-year period of time. Results: Median age was 47.3 years and four were males. Clinical presentation was related to local mass effect in all. Tumors occurred in the orbits (5/62.5%), intracranial dura attached (2), and the spinal medulla (1). The neuropathology showed the presence of hemangiopericytoma type (2), classic type (3), and mixed type (3). Histological anaplasia was present in two cases. Widespread/total immunoreactivity for vimentin, CD34, and Bcl-2 was present in all. Gross total removal was conducted in the majority (6/75%) and subtotal removal in 2 (25%). Three patients were submitted to adjuvant treatment (radiosurgery and radiotherapy). Recurrence occurred in four patients, 13–120 months after surgical intervention. Anaplasia was present in one case of recurrence. Conclusion: Our case series confirms the clinical and neuropathological diversity of CNS and orbital SFTs. Studies with longer follow-up periods are necessary to better understand the clinical behavior and prognosis of the SFT in the CNS and orbits. PMID:29682031

    2016-05-01

    Statins are one of the most commonly prescribed drugs in New Zealand, with 525 772 or 16.5% of the adult New Zealand population prescribed a statin between June 2013 and July 2014. While generally well-tolerated, statins are known to cause a range of muscle-related side effects, ranging from myalgia to life-threatening rhabdomyolysis. Recently, it has been recognised that in rare instances, statins can induce an immune-mediated necrotising myositis with antibodies against 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR), the enzymatic target of statins. In 2014, anti-HMGCR antibody testing was introduced to Canterbury Health Laboratories (CHL), with this being the only laboratory in New Zealand performing this test during the period of this case series. This article describes an index case and characterises the clinical features of a subsequent 12-month series. From this series, we estimated the yearly incidence of HMGCR-associated myositis at 1.7/million/year or ~1/90 000 New Zealand statin users. © 2016 Royal Australasian College of Physicians.

    Pain is a common and significant feature of burn injury. The use of intravenous opioids forms the mainstay of procedural burn pain management, but in an outpatient setting, the demand for novel agents that do not require parenteral access, are easy to administer and have a rapid onset are urgently needed. One such agent is the inhaled anaesthetic agent, methoxyflurane (MF). The aim of this study was to conduct a pilot investigation into the clinical effectiveness of MF inhaler on pain and anxiety scores in patients undergoing burn wound care procedures in an outpatient setting. A prospective case series involved recruiting patients undergoing a burn wound care procedure in an ambulatory burn care setting. Pain and anxiety were assessed using numerical rating scales. Overall, median numerical pain rating score was significantly higher post-dressing [pre-dressing: 2; interquartile range (IQR): 1-3 versus post-dressing: 3; IQR 1·5-4; P = 0·01], whereas median numerical anxiety score significantly reduced following the dressing (pre-dressing: 5; IQR 4-7 versus post-dressing: 2; IQR 1-2; P < 0·001). Our study suggests that there is a role for MF in the pain management armamentarium in those undergoing burn care procedures in the ambulatory care setting. However, there is an urgent need for larger case series and randomised controlled trials to determine its overall clinical effectiveness. © 2012 The Authors.

    Hypothalamic-pituitary (HP) neurosarcoidosis (NS) accounts for 0.5 % cases of sarcoidosis and 1 % of HP masses. Correlative data on endocrine and neurological outcomes is lacking. Retrospective case series and literature review of presentation, treatment and outcome of HP NS. Our series includes 4 men, ages 34-59, followed for a median of 7.3 years (range 1.5-17). All had optic neuropathy, multiple pituitary hormone abnormalities (PHAs) and other organ involvement by sarcoidosis (lung, sino-nasal, brain/spine and facial nerve). Two patients had central diabetes insipidus and one impaired thirst with polydipsia. After treatment with high-dose glucocorticoids, optic neuropathy improved in one case and stabilized in the others. After treatment, HP lesions improved radiologically, but PHAs persisted in all cases. Review of four published series on HP NS in addition to ours yielded 46 patients, age 37 ± 11.8 years, 65 % male. PHAs consisted of anterior hypopituitarism (LH/FSH 88.8 %, TSH 67.4 %, GH 50.0 %, ACTH 48.8 %), hyperprolactinemia (48.8 %) and diabetes insipidus (65.2 %). PHAs were the first sign of disease in 54.3 % patients. Vision problems occurred in 28.3 % patients, but optic neuropathy was not well documented in previous series. Most patients (93.5 %) received high-dose glucocorticoids followed by taper; 50 % also received other immunomodulators, including methotrexate, mycophenolate mofetil, cyclosporine, azathioprine, infliximab and hydrochloroquine. Only 13 % patients showed improvement in PHAs. All-cause mortality was 8.7 %. HP NS is a serious disease requiring multidisciplinary treatment and lifelong follow-up. Prospective multicentric studies are needed to determine a more standardized approach to HP NS and outline predictors of disease outcome.

    2015-01-01

    Although the epidemiology of civilian trauma is distinct from that encountered in combat, in both settings, extremity hemorrhage remains a major preventable cause of potential mortality. The current paper describes the largest case series in the literature in which police officers arriving prior to emergency medical services applied commercially available field tourniquets to civilian victims of violent trauma. Although all 3 patients with vascular injury arrived at the receiving emergency department in extremis, they were successfully resuscitated and survived to discharge without major morbidity. While this outcome is likely multifactorial and highlights the exceptional care delivered by the modern trauma system, tourniquet application appears to have kept critically injured patients alive long enough to reach definitive trauma care. No patient had a tourniquet-related complication. This case series suggests that law enforcement officers can effectively identify indications for tourniquets and rapidly apply such life-saving interventions.

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

    Although Streptococcus pneumoniae is an important pathogen of humans, pneumococcal cholangitis is rare because of the rapid autolysis of S. pneumoniae. The aim of this case series was to review patients with bile cultures positive for S. pneumoniae. This study was a single center retrospective case series review of patients with S. pneumoniae in their bile at a tertiary-care cancer center between September 2002 and August 2015. Subjects consisted of all patients in whom S. pneumoniae was isolated in their bile during the study period. Bile specimens for culture were obtained from biliary drainage procedures such as endoscopic retrograde biliary drainage, endoscopic nasobiliary drainage, and percutaneous transhepatic biliary drainage. There were 20 patients with bile cultures positive for S. pneumoniae during the study period. All patients presented with extrahepatic obstructive jaundice due to hepatopancreatobiliary tumors. Nineteen of 20 patients underwent the placement of plastic intrabiliary tubes. The mean time between the first-time drainage and the positive culture was 26 days (range 0-313 days). Although 12 of 20 patients met our definition of cholangitis, 5 were clinically treated with antibiotics based on a physician's assessment of whether there was a true infection. The present study is the largest case series of patients with S. pneumoniae in their bile. Based on our findings, the isolation of S. pneumoniae from bile may be attributed to the placement of biliary drainage devices.

    2013-01-01

    Background Toxic chemical exposures are estimated to account for 1–5% of all olfactory disorders. Both olfactory neurons and taste buds are in direct contact with environmental agents because of their relatively unprotected anatomic locations, thereby making them susceptible to damage from acute and chronic toxic exposures. The aim of this study was to illustrate different aspects of the diagnostic and therapeutic approach to this disorder using a series of case reports and review of the literature. Methods Cases were selected for inclusion based on a retrospective chart review of patients who presented to a university-based nasal dysfunction clinic with toxin-induced olfactory or gustatory dysfunction between January 1985 and December 2008. Workup included complete history, otolaryngologic examination, psychophysical testing, and imaging. Results Patient ages ranged from 31 to 67 years (mean, 49.3 years). Etiology of chemosensory impairment included exposure to ammonia, isodecanes, hairdressing chemicals, chemotherapy, gasoline, and intranasal zinc. Five of the seven patients (71%) presented with olfactory dysfunction alone, one patient (14%) presented with dysgeusia alone, and one patient (14%) presented with both smell and taste loss. Only one patient (14%) reported parosmias. Tests of olfaction revealed normosmia in one patient (14%), mild-to-moderate hyposmia in one patient (14%), and severe hyposmia to anosmia in five patients (72%). Both patients who reported taste disorders had hypogeusia on testing. Conclusion This case series illustrates the wide spectrum of this disorder and provides a framework for the workup and treatment of these patients. PMID:19958605

    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

    Hyponatremia during labor and delivery may result in severe maternal and neonatal sequelae. Our aim was to describe the direct effect of hyponatremia in labor on pregnancy outcome. A case series of parturients diagnosed with hyponatremia during labor and their neonates. Clinical presentation, laboratory workup, and maternal and neonatal outcomes are presented. Four parturients and their corresponding six neonates were diagnosed with hyponatremia. Of these, two cases were caused by water intoxication and two were preeclampsia induced. While two were identified due to maternal or neonatal symptoms, two were diagnosed by routine laboratory testing. In all cases, low maternal sodium resulted in similarly low neonatal sodium. Neonatal symptoms included respiratory distress syndrome (RDS), lethargy, and jaundice. Psychogenic drinking during labor and preeclampsia may predispose to maternal hyponatremia, resulting in neonatal hyponatremia. Early recognition and treatment can prevent further maternal deterioration and adverse neonatal sequelae.

    Purpose: To present various forms of uveitis and/or retinal vasculitis attributed to Bartonella infection and review the impact of this microorganism in patients with uveitis. Methods: Retrospective case series study. Review of clinical records of patients diagnosed with Bartonella henselae and Bartonella quintana intraocular inflammation from 2001 to 2010 in the Ocular Inflammation Department of the University Eye Clinic, Ioannina, Greece. Presentation of epidemiological and clinical data concerning Bartonella infection was provided by the international literature. Results: Eight patients with the diagnosis of Bartonella henselae and two patients with B. quintana intraocular inflammation were identified. Since four patients experienced bilateral involvement, the affected eyes totaled 14. The mean age was 36.6 years (range 12–62). Uveitic clinical entities that we found included intermediate uveitis in seven eyes (50%), vitritis in two eyes (14.2%), neuroretinitis in one eye (7.1%), focal retinochoroiditis in one eye (7.1%), branch retinal vein occlusion (BRVO) due to vasculitis in one eye (7.1%), disc edema with peripapillary serous retinal detachment in one eye (7.1%), and iridocyclitis in one eye (7.1%). Most of the patients (70%) did not experience systemic symptoms preceding the intraocular inflammation. Antimicrobial treatment was efficient in all cases with the exception of the case with neuroretinitis complicated by anterior ischemic optic neuropathy and tubulointerstitial nephritis. Conclusion: Intraocular involvement caused not only by B. henselae but also by B. quintana is being diagnosed with increasing frequency. A high index of suspicion is needed because the spectrum of Bartonella intraocular inflammation is very large. In our study the most common clinical entity was intermediate uveitis. PMID:21750616

    Introduction: The chin (mentum) is vital to the human facial morphology as it contributes to the facial aesthetics and harmony both on frontal and lateral views. Osseous genioplasty, the alteration of the chin through skeletal modification, can lead to significant enhancement of the overall facial profile. Aim and Study Design: A case series was designed to study the long-term results of osseous genioplasty in Indian patients with regard to patient satisfaction, complications, and long-term stability. Materials and Methods: All subjects who underwent osseous genioplasty either alone or as a component of orthognathic surgery between January 1992 and December 2010, with a minimum follow-up of 2 years, were included. The genioplasty was performed using standard protocols of assessment and execution. Post-operative evaluation included patient satisfaction, complications and radiological evidence of long-term stability. A comprehensive score was formulated for the purpose of the study. Results: Thirty-seven subjects underwent osseous genioplasty with at least 2 years of follow-up in the study period. This included 17 male and 20 female subjects, with a mean age of 22.8 years (15-52 years) and a mean follow-up of 3 years 4 months (2 years to 4 years and 11 months). Nineteen subjects underwent isolated genioplasty while 18 underwent genioplasty as a part of orthognathic surgery. The procedures included advancement (22), pushback (9), side-to-side (4) and vertical reduction (2) genioplasty. Thirty-six subjects (97.3%) were extremely pleased with the results with only one subject expressing reservations, without, however, demanding any further procedure. There were no significant complications. The osteotomised segment was well maintained in its new position with good bony union and minimal resorption. Overall, 35 (94.6%) cases had excellent results and 2 (4.4%) cases had good results, according to the comprehensive score. Conclusions: Osseous genioplasty is a safe and

  1. Central neuraxial anaesthesia presenting with spinal myoclonus in the perioperative period: a case series

    PubMed Central

    2009-01-01

    Introduction Perioperative spinal myoclonus is extremely rare. Many anaesthetists and perioperative practitioners may not diagnose or manage this complication appropriately when it occurs. This case report of unusual acute spinal myoclonus following regional anaesthesia highlights certain aspects of this rare complication that have not previously been published. Case presentations A series of four consecutive patients who developed acute lower-limb myoclonus following spinal or epidural anaesthesia are described. The case series occurred at three different hospitals and involved four anaesthetists over a 3-year period. Two Caucasian men, aged 90-years-old and 67-years-old, manifested unilateral myoclonus. Two Caucasian women, aged 64-years-old and 53-years-old, developed bilateral myoclonus. Myoclonus was self-limiting in one patient, treated with further regional anaesthesia in one patient and treated with intravenous midazolam in two patients. The overall outcome was good in all patients, with no recurrence or sequelae in any of the patients. Conclusion This case series emphasizes that spinal myoclonus following regional anaesthesia is rare, has diverse pathophysiology and can have diverse presentations. The treatment of perioperative spinal myoclonus should be directed at the aetiology. Anaesthetists and perioperative practitioners who are unfamiliar with this rare complication should be reassured that it may be treated successfully with midazolam. PMID:19830168

  2. Migraine and tension-type headache treated with stromal vascular fraction: a case series

    2014-01-01

    Introduction Chronic migraines and tension-type headaches are debilitating diseases affecting 1.4 to 2.2% of the population with both quality of life and economic implications. To date, the pain associated with migraine and tension-type headaches has been controlled with a range of medications, with varying levels of success. In addition, the side-effect profile of these medications, as well as their potential for addiction, has been a cause for concern for both patients and physicians. Case presentations Four women with long histories of migraine or frequent tension-type headache that meet the International Classification of Headache Disorders criteria for Chronic Migraine or Tension-type Headaches were given a systemic treatment(s) of autologous stromal vascular fraction or autologous ‘StroMed’ isolated from lipoaspirate. StroMed is stromal vascular fraction cells prepared by ultrasonic cavitation. Two of the four patients, both of whom are Arab women aged 40 and 36 years, ceased having migraines after 1 month, for a period of 12 to 18 months. The third patient, a Slavic woman aged 43 years, had a significant decrease in the frequency and severity of migraines with only seven migraines over 18 months. The fourth patient, an Asian woman aged 44 years, obtained a temporary decrease for a period of a month and was retreated 18 months later and has been free of migraines to date for 1 month. Pain medication was typically reduced from prescribed opioid analgesia to non-steroidal anti-inflammatory drugs and paracetamol. Conclusions This case series is the first to provide evidence of the efficacy of autologous StroMed and stromal vascular fraction in the treatment of migraine and tension-type headache. The treatment of this disease by stromal vascular fraction adds a new dimension to its clinical applicability and suggests a relatively simple treatment that may help address the symptoms of the disease. Given what is known about the components of the stromal

    Occupational therapy practitioners frequently identify opportunities for international practice. The World Health Organization and the World Federation of Occupational Therapists have encouraged occupational therapists to address transnational issues, social inclusion, and equal access to opportunities grounded in meaningful occupation (WFOT, 2012). This case study describes a partnership between two U.S. schools of occupational therapy and a Cuban community based pediatric clinic. It examines the dynamics that have sustained the partnership despite political, economic, and logistical barriers. The literature is scrutinized to show how this case study fits into other accounts of collaborative international partnerships. Particularly, it investigates structural and institutional conditions that shape international sustainable partnerships. In doing so, we answer the following questions: (1) Under which circumstances do international partnerships emerge and flourish? (2) What structural and institutional conditions shape international sustainable partnerships? And (3) How do partners perceive and experience the bilateral international partnership? It also discusses and illustrates the foundations and development of international partnerships that succeed. Through the use of a case study we illustrate the development of this partnership. Finally, we consider the next steps of this particular sustainable and collaborative international partnership. © 2015 John Wiley & Sons, Ltd.

  4. A Method for Comparing Multivariate Time Series with Different Dimensions

    In many situations it is desirable to compare dynamical systems based on their behavior. Similarity of behavior often implies similarity of internal mechanisms or dependency on common extrinsic factors. While there are widely used methods for comparing univariate time series, most dynamical systems are characterized by multivariate time series. Yet, comparison of multivariate time series has been limited to cases where they share a common dimensionality. A semi-metric is a distance function that has the properties of non-negativity, symmetry and reflexivity, but not sub-additivity. Here we develop a semi-metric – SMETS – that can be used for comparing groups of time series that may have different dimensions. To demonstrate its utility, the method is applied to dynamic models of biochemical networks and to portfolios of shares. The former is an example of a case where the dependencies between system variables are known, while in the latter the system is treated (and behaves) as a black box. PMID:23393554

    Background. Malaria still remains a public health problem in developing countries and changing environmental and climatic factors pose the biggest challenge in fighting against the scourge of malaria. Therefore, the study was designed to forecast malaria cases using climatic factors as predictors in Delhi, India. Methods. The total number of monthly cases of malaria slide positives occurring from January 2006 to December 2013 was taken from the register maintained at the malaria clinic at Rural Health Training Centre (RHTC), Najafgarh, Delhi. Climatic data of monthly mean rainfall, relative humidity, and mean maximum temperature were taken from Regional Meteorological Centre, Delhi. Expert modeler of SPSS ver. 21 was used for analyzing the time series data. Results. Autoregressive integrated moving average, ARIMA (0,1,1) (0,1,0)(12), was the best fit model and it could explain 72.5% variability in the time series data. Rainfall (P value = 0.004) and relative humidity (P value = 0.001) were found to be significant predictors for malaria transmission in the study area. Seasonal adjusted factor (SAF) for malaria cases shows peak during the months of August and September. Conclusion. ARIMA models of time series analysis is a simple and reliable tool for producing reliable forecasts for malaria in Delhi, India.

    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.

    The purpose of the study was to describe the main clinical and epidemiologic characteristics, treatment options, and outcome in a large series of patients with periocular and orbital amyloidosis. This is a retrospective, descriptive, observational study of a case series of 14 patients with periocular and orbital amyloidosis and is a review of previously published cases with this diagnosis between September 2004 and January 2015. In this study, we analyzed our 14 patients in conjunction with 69 well-documented cases of orbital and/or periocular amyloidosis previously reported, with a total of 83. Of these, 54 were female (65.1 %), 28 male (33.7 %), and one with unspecified gender. The mean age at diagnosis was 54.9 years (range, 18-87). The localization of the amyloidosis was classified as superficial, deep and combined, with involvement of 53 (63.9 %), 26 (31.3 %), and four cases (4.8 %) in each group, respectively. The main findings in superficial amyloidosis were mass or tissue infiltration (84.9 %) and ptosis (30.2 %) and, in the cases with deep involvement, mass (65.4 %), proptosis (57.7 %), limited ocular movements (34.6 %), ocular displacement (30.8 %), and ptosis (26.9 %). The cases with combined involvement presented with signs and symptoms of the two groups. Regarding the outcome, 43 patients were reported stable after the diagnosis and 21 had recurrence or required new surgical procedures. Periocular and orbital amyloidosis is a rare disease that can present with a variety of symptoms and signs depending on the localization and extension of involvement. Its prompt recognition is important in order to investigate systemic disease, which will affect the prognosis of each case.

    The SonixGPS™ is a novel needle tracking system that has recently been approved in Canada for ultrasound-guided needle interventions. It allows optimization of needle-beam alignment by providing a real-time display of current and predicted needle tip position. Currently, there is limited evidence on the effectiveness of this technique for performance of real-time spinal anesthesia. This case series reports performance of the SonixGPS system for real-time ultrasound-guided spinal anesthesia in elective patients scheduled for joint arthroplasty. In this single-centre case series, 20 American Society of Anesthesiologists' class I-II patients scheduled for lower limb joint arthroplasty were recruited to undergo real-time ultrasound-guided spinal anesthesia with the SonixGPS after written informed consent. The primary outcome for this clinical cases series was the success rate of spinal anesthesia, and the main secondary outcome was time required to perform spinal anesthesia. Successful spinal anesthesia for joint arthroplasty was achieved in 18/20 patients, and 17 of these required only a single skin puncture. In 7/20 (35%) patients, dural puncture was achieved on the first needle pass, and in 11/20 (55%) patients, dural puncture was achieved with two or three needle redirections. Median (range) time taken to perform the block was 8 (5-14) min. The study procedure was aborted in two cases because our clinical protocol dictated using a standard approach if spinal anesthesia was unsuccessful after three ultrasound-guided insertion attempts. These two cases were classified as failures. No complications, including paresthesia, were observed during the procedure. All patients with successful spinal anesthesia found the technique acceptable and were willing to undergo a repeat procedure if deemed necessary. This case series shows that real-time ultrasound-guided spinal anesthesia with the SonixGPS system is possible within an acceptable time frame. It proved effective with

    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.

    Ibogaine is a naturally occurring hallucinogen with postulated anti-addictive qualities. While illegal domestically, a growing number of individuals have sought it out for treatment of opiate dependence, primarily in poorly regulated overseas clinics. Existing serious adverse events include cardiac and vestibular toxicity, though ours is the first report of mania stemming from its use. To report on a case series of psychiatric emergency room patients whose unregulated use of ibogaine resulted in mania in three patients with no prior diagnosis of bipolar illness. Review and summarize charts of three cases. Relevant literature was also reviewed for discussion. Two cases of reported ibogaine ingestion for self-treatment of addictions, and one for psycho-spiritual experimentation resulted in symptoms consistent with mania. No prior reports of mania were found in the literature, and the literature suggests growing popularity of ibogaine's use. The three cases presented demonstrate a temporal association between ibogaine ingestion and subsequent development of mania. In light of these cases, clinicians faced with a new onset mania may benefit from careful substance use and treatment history, specifically regarding opiates. In the vulnerable and often desperate addiction population, in particular, the number of patients seeking this treatment appears to be growing. We advise clinicians to be prepared for discussing the safety, efficacy, and paucity of good data regarding ibogaine with patients who may be considering its use.

    Case series describing the outcomes of individual patients with hip osteoarthritis treated with manual physical therapy and exercise. Seven patients referred to physical therapy with hip osteoarthritis and/or hip pain were included in this case series. All patients were treated with manual physical therapy followed by exercises to maximize strength and range of motion. Six of 7 patients completed a Harris Hip Score at initial examination and discharge from physical therapy, and 1 patient completed a Global Rating of Change Scale at discharge. Three males and 4 females with a median age of 62 years (range, 52-80 years) and median duration of symptoms of 9 months (range, 2-60 months) participated in this case series. The median number of physical therapy sessions attended was 5 (range, 4-12). The median increase in total passive range of motion of the hip was 82 degrees (range, 70 degrees-86 degrees). The median improvement on the Harris Hip Score was 25 points (range, 15-38 points). The single patient who completed the Global Rating of Change Scale at discharge reported being "a great deal better." Numeric pain rating scores decreased by a mean of 5 points (range, 2-7 points) on 0-to-10-point scale. All patients exhibited reductions in pain and increases in passive range of motion, as well as a clinically meaningful improvement in function. Although we can not infer a cause and effect relationship from a case series, the outcomes with these patients are similar to others reported in the literature that have demonstrated superior clinical outcomes associated with manual physical therapy and exercise for hip osteoarthritis compared to exercise alone.

    Acute burns suffered from contact with environmentally heated roadways and walkways are a rare entity. The aim of this report is to assess the information gained from the treatment of a series of patients. A retrospective review of a consecutive series of cases, where operative treatment was necessary, that occurred during July 2010 in southern Arizona. Seven patients were included, with an average total body surface area burn of 10.2%. Direct fascial excision and tangential excision were carried out on three and four patients, respectively. Although tangential excision was carried out to normal endpoints, there was commonly a need for repetitive debridement. The total hospital costs were over $4,400,000 (£2,730,000). Burns suffered from contact with roadways/walkways are often deeper than suggested by their appearance. Direct fascial excision minimises the number of debridement sessions. We hypothesise that the failure to offload pressure on these wounds may be a causative factor in their observed deepening.

    Anophthalmic socket cysts are challenging to remove and incomplete excision has been shown to increase the risk of recurrence. This case series describes a novel technique utilising the fibrin sealant Tisseel (Baxter AG, Vienna, Austria) to retain the socket cyst integrity during surgical removal to facilitate its complete excision. Five patients were included and followed up for a minimum of 1 year, and there were no signs of recurrence in any of the cases. The surgical technique is described and illustrated. This technique is a safe way of simplifying challenging socket cyst surgery.

    2017-07-01

    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

    Shiitake (Lentinula edodes) is an edible mushroom which was initially grown in Japan and China and is now sold on the European market. Flagellate erythema may arise following shiitake consumption and was first described in Japan in 1974. This paper reports a French shiitake dermatitis case series. The findings of retrospective study of shiitake dermatitis cases, reported to French Poison Control Centres (PCC) from January 2000 to December 2013, are reported. Among 32 exposed patients, 15 presented flagellate urticarial lesions after raw shiitake consumption. The first case of this series was reported in 2006 and the last nine cases were reported as of 2012. After shared meals, no symptoms were reported among guests, who preferred cooked shiitake to the raw mushroom. In this series, rashes appeared 12 h to 5 days (median: 24 h) after raw shiitake ingestion. Linear and itchy urticarial lesions formed on the trunk, arms, and legs within a few hours and persisted for 3-21 days. In four cases, rash and pruritus were either triggered or worsened by sun exposure. Eleven patients received corticosteroids, antihistamines, or both. All patients completely recovered. Due to the rapidly increasing consumption of exotic food in Western countries, it is no surprise that cases of shiitake dermatitis are now appearing in Europe. The mechanism of shiitake dermatitis is thought to be toxic and due to lentinan, a polysaccharide component of the mushroom. There is no specific validated treatment for shiitake dermatitis. Health professionals and the general population should be aware of both the risk associated with raw shiitake consumption and of the good prognosis of this very spectacular and uncomfortable toxic dermatitis.

    Recent randomized clinical trials have established the efficacy of Comprehensive Behavioral Intervention for Tics (CBIT) in treating children and adults with Tourette syndrome and persistent tic disorders. However, the standard CBIT protocol uses a weekly outpatient treatment format (i.e., 8 sessions over 10 wk), which may be inconvenient or impractical for some patients, particularly patients, who are required to travel long distances in order to receive care. In contrast, an intensive outpatient program may increase accessibility to evidence-based behavioral treatments for Tourette syndrome and other persistent tic disorders by eliminating the necessity of repeated travel. This case series evaluated the use of an intensive outpatient program CBIT (IOP CBIT) for the treatment of 2 preadolescent males (ages 10 and 14 years) with Tourette syndrome. The IOP CBIT treatment protocol included several hours of daily treatment over a 4-d period. Both children evidenced notable reductions in their tics and maintained treatment gains at follow-up. Moreover, both patients and their parents expressed treatment satisfaction with the IOP CBIT format. This case series addresses an important research gap in the behavioral treatment of tic disorders literature. The patients’ treatment outcomes indicate that IOP CBIT is a promising treatment that warrants more systematic investigation. PMID:25325069

    Dofetilide is a class III antiarrhythmic used for treating atrial dysrhythmias. Though its adverse effects are well described in routine use, very little is known about dofetilide toxicity in overdose. This is a retrospective case series of consecutive patients reported to our poison center after dofetilide overdose. Twenty-seven cases were included. Seventeen patients were treated at a healthcare facility, and of these, eight were admitted. Twenty-one patients took one extra capsule, four took someone else's medication, one took three extra capsules, and one had a large intentional overdose. Ten patients had co-ingestants reported, including three QT-prolonging agents. No one required cardioversion, defibrillation, CPR, or overdrive pacing. The patient who reported taking 90 times his usual dose in suicide attempt was the only patient to have significant clinical effects. He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy. He received magnesium sulfate and potassium chloride supplementation. In this series, unintentional small overdoses did not result in significant clinical effects and were often managed successfully at home, despite the fact that information showing a single capsule can cause torsades. This study is limited by its small sample size, retrospective design, and reliance on incomplete information.

    Cat-scratch disease (CSD) is a systemic infectious disease. The most well-known posterior segment presentation is neuroretinitis with a macular star. In this study, we present a case series emphasising the heterogeneity of the disease and the various posterior segment manifestations. A retrospective case series of consecutive patients presenting with posterior segment CSD, over a 5-year period (2010 to 2015), at two ophthalmological centres in Midi-Pyrénées. Twelve patients (17 eyes) were included, of whom 11 (92%) presented with rapidly decreasing visual acuity, with 6 of these (50%) extremely abrupt. CSD was bilateral in 5 (42% of all patients). Posterior manifestations were: 12 instances of optic nerve edema (100%), 8 of focal chorioretinitis (67%) and only 6 of the classic macular edema with macular star (25% at first examination, but 50% later). Other ophthalmological complications developed in three patients; one developed acute anterior ischemic optic neuropathy, one a retrohyaloid hemorrhage and one a branch retinal artery occlusion, all secondary to occlusive focal vasculitis adjacent to focal chorioretinitis. Classical neuroretinitis with macular star is not the only clinical presentation of CSD. Practitioners should screen for Bartonella henselae in all patients with papillitis or focal chorioretinitis.

    Gender nonconforming youth are at risk for body dissatisfaction and disordered eating. Currently, only a small body of literature addresses this high-risk group. The five cases in this series highlight important themes for this patient population from an interdisciplinary perspective. Identified themes include increased risk for self-harm/suicide, complex psychiatric, and medical implications of delay to treatment for either gender dysphoria or disordered eating, and the importance of collaborative management to maximize care and facilitate healthy development to adulthood. The purpose of this case series is to expand the interdisciplinary discussion regarding the breadth of presentation and management considerations for gender nonconforming adolescents with disordered eating. An interdisciplinary approach to care might enhance access to comprehensive, collaborative treatment for disordered eating, and gender dysphoria in this unique population. © 2018 Wiley Periodicals, Inc.

    Following the International Subarachnoid Aneurysm Trial (ISAT), evolving treatment modalities for acute aneurysmal subarachnoid hemorrhage (aSAH) has changed the case mix of patients undergoing urgent surgical clipping. To update our knowledge on outcome predictors by analyzing admission parameters in a pure surgical series using variable importance ranking and machine learning. We reviewed a single surgeon's case series of 226 patients suffering from aSAH treated with urgent surgical clipping. Predictions were made using logistic regression models, and predictive performance was assessed using areas under the receiver operating curve (AUC). We established variable importance ranking using partial Nagelkerke R2 scores. Probabilistic associations between variables were depicted using Bayesian networks, a method of machine learning. Importance ranking showed that World Federation of Neurosurgical Societies (WFNS) grade and age were the most influential outcome prognosticators. Inclusion of only these 2 predictors was sufficient to maintain model performance compared to when all variables were considered (AUC = 0.8222, 95% confidence interval (CI): 0.7646-0.88 vs 0.8218, 95% CI: 0.7616-0.8821, respectively, DeLong's P = .992). Bayesian networks showed that age and WFNS grade were associated with several variables such as laboratory results and cardiorespiratory parameters. Our study is the first to report early outcomes and formal predictor importance ranking following aSAH in a post-ISAT surgical case series. Models showed good predictive power with fewer relevant predictors than in similar size series. Bayesian networks proved to be a powerful tool in visualizing the widespread association of the 2 key predictors with admission variables, explaining their importance and demonstrating the potential for hypothesis generation.

    Odontogenic cysts and tumors of the maxilla may be amendable to management by endonasal endoscopic techniques, which may reduce the morbidity associated with open procedures and avoid difficult reconstruction. To perform a systematic review that evaluates the feasibility and outcomes of endoscopic techniques in the management of different odontogenic cysts. A case series of our experience with these minimally invasive techniques was assembled for insight into the technical aspects of these procedures. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used to identify English-language studies that reported the use of endoscopic techniques in the management of odontogenic cysts. Several medical literature data bases were searched for all occurrences in the title or abstract of the terms "odontogenic" and "endoscopic" between January 1, 1950, and October 1, 2016. Publications were evaluated for the technique used, histopathology, complications, recurrences, and the follow-up period. A case series of patients who presented to a tertiary rhinology clinic and who underwent treatment of odontogenic cysts by an endoscopic technique was included. A systematic review identified 16 case reports or series that described the use of endoscopic techniques for the treatment of odontogenic cysts, including 45 total patients. Histopathologies encountered were radicular (n = 16) and dentigerous cysts (n = 10), and keratocystic odontogenic tumor (n = 12). There were no reported recurrences or major complications for a mean follow-up of 29 months. A case series of patients in our institution identified seven patients without recurrence for a mean follow-up of 10 months. Endonasal endoscopic treatment of various odontogenic cysts are described in the literature and are associated with effective treatment of these lesions for an average follow-up period of >2 years. These techniques have the potential to reduce morbidity associated with the resection of these

    Pediatric digital necrosis resulting in revision amputation is a devastating outcome following digital dressing application. We report a series of 4 pediatric patients (age: 21 months-11 years) who presented for surgical consultation related to digital ischemia and irreversible necrosis following the application of Coban digital dressings. A review of the literature demonstrated that such injuries had not previously been described. In our case series, Coban dressing was utilized as a deterrent for thumb sucking, fingertip tuft fractures with nail bed lacerations, and a phalanx fracture secondary to crush injury. All 4 children suffered digital necrosis secondary to Coban dressings and ultimately required revision amputation. We discuss risks factors, application practices, and strategies to minimize complications with digital dressings in the pediatric population with the intent of creating awareness among hand surgeons to help promote safe practices and improve patient outcomes.

The emergence of a new hypervirulent variant of Klebsiella pneumoniae, which can cause serious infections in the Asian population, is under investigation. We report a case series of six Asian patients hospitalized at our institution from January 2013 to November 2015 for liver abscess due to Klebsiella pneumoniae. Case Report: Charts of six Asian patients were retrospectively reviewed. Four patients were male and two were female. The mean age was 53 years (range: 35–64 years). All patients had no known past medical history of immunodeficiency. Three patients had multiple liver abscesses at the time of initial presentation. In five patients, the source of entry of the pathogenic microorganism was unknown and in one patient the suspected source of entry was the gastrointestinal tract. In three patients there was also concomitant Klebsiella pneumoniae bacteremia. The mean duration of antibiotic treatment was seven weeks and the mean duration of hospital stay was 13.5 days. Conclusions: Liver abscess should always be included in the differential diagnosis in cases of sepsis without obvious source and/or in the clinical scenarios of fever, abdominal pain, and liver lesions.

    Bleeding frequently occurs in patients undergoing placement of a left ventricular assist device (LVAD). Clinical factors that have been identified as contributing to peri-procedural bleeding include LVAD implantation after an acute myocardial infarction and preoperative use of antiplatelet agents. In this report, we describe the use of cangrelor for preoperative antiplatelet bridging to LVAD in five post myocardial infarction patients with cardiogenic shock that had recently undergone percutaneous coronary intervention. During the cangrelor bridging period, no cases of thrombotic or major bleeding events occurred. During the first week following LVAD implantation, two patients experienced a major bleeding (each case required chest exploration for suspected hemorrhage). To our knowledge, this is the first series describing cangrelor use for antiplatelet bridging in patients undergoing LVAD implantation. While this series suggest cangrelor could possibly be a safe and effective antiplatelet bridging strategy, further research is needed to identify the optimal antithrombotic strategy in cardiogenic shock patients undergoing LVAD implantation who have recently undergoing percutaneous coronary intervention.

    To analyze a case series of patients who underwent injection of industrial liquid silicone in a clandestine manner and by unauthorized persons. We conducted a retrospective analysis of medical records of patients treated between September 2003 and December 2010. Data regarding gender, age, location and volume of silicone injected, time between application and clinical manifestations, complications, treatment and outcome were collected. Early manifestations were defined as occurring within 30 days of injection and late manifestations, the ones arising after this period. We treated 12 patients, eight were male, seven transsexuals. The volume injected ranged from 5 ml to 2000 ml, being unknown in three cases. The most often used injected sites were the thighs and buttocks. Eight patients had early manifestations, with inflammation and/or infection. Surgical debridement was necessary in five cases. Three patients with a history of injection in the breast region underwent adenomastectomy. There was one death due to refractory septic shock. The use of industrial liquid silicone should be completely contraindicated as a filling material and modification of body contouring, and may have serious complications, even death.

    Arterial dissection is a rare complication of pregnancy and puerperium. There have been reports of aortic, coronary and cervical artery dissection in association with preeclampsia, however, vertebral artery dissection is rarely reported particularly in the antenatal setting in the presence of a Hypertensive Disorder of Pregnancy (HDP).The general annual incidence of symptomatic spontaneous cervicocephalic arterial dissection is 0.0026 % and a data registry reported that 2.4 % of these occurred in the post-partum period. The actual incidence of vertebral artery dissection in HDP is unknown as the current literature consists of case series and reports only with most documenting adverse outcomes. Given the presence of collateral circulation, unilateral vertebral artery dissections may go unrecognised and may be more common than suspected. We present a case series of four patients with vertebral artery dissection in association with HDP, two of which occurred in the antenatal setting and two in the post-partum setting. All our patients had favourable outcome with no maternal neurological deficit and live infants. Our discussion covers the proposed pathophysiology of vertebral artery dissection in HDP and the management of it. Our case series highlights the need to consider VAD an important differential diagnosis when assessing pregnant women with headache and neck pain particularly in the context of HDP.

    The research provides an understanding of pandemic information needs and informs professional development initiatives for librarians in disaster medicine. Utilizing a multisite, comparative case series design, the researchers conducted semi-structured interviews and examined supplementary materials in the form of organizational documents, correspondence, and websites to create a complete picture of each case. The rigor of the case series was ensured through data and investigator triangulation. Interview transcripts were coded using NVivo to identify common themes and points of comparison. Comparison of the four cases revealed a distinct difference between "client-initiated" and "librarian-initiated" provision of pandemic information. Librarian-initiated projects utilized social software to "push" information, whereas client-initiated projects operated within patron-determined parameters to deliver information. Health care administrators were identified as a key audience for pandemic information, and news agencies were utilized as essential information sources. Librarians' skills at evaluating available information proved crucial for selecting best-quality evidence to support administrative decision making. Qualitative analysis resulted in increased understanding of pandemic information needs and identified best practices for disseminating information during periods of high organizational stress caused by an influx of new cases of an unknown infectious disease.

    2015-12-01

    Complications related to inflatable penile prosthesis (IPP) and artificial urinary sphincter (AUS) reservoirs are rare, potentially life threatening, and poorly described in the literature. As more devices are implanted, the incidence of reservoir-related complications may increase, and it will be important to recognize the relevant signs and symptoms. We present a case series of reservoir-related complications presenting to our institution for treatment. We also reviewed all accounts of reservoir-related complications within the urologic literature. Three cases of reservoir-related complications are presented. Case 1 involves erosion of an intact AUS reservoir into the cecum of a patient with a history of myelomeningocele and bladder augmentation. Case 2 involves an IPP reservoir causing vascular compression, resulting in open exploration and repositioning of the reservoir. Case 3 involves intraperitoneal migration of a retained IPP reservoir to a subhepatic area, which was then removed laparoscopically. Literature review yielded descriptions of eight cases of intestinal complications, five cases of vascular complications, but zero reports of migration to a subhepatic area. Other notable complications include 20 reported cases of reservoir erosion into the bladder and inguinal herniation of the reservoir. Complications involving urologic prosthesis reservoirs, although rare, can have serious implications for patients. A high index of suspicion and familiarity with treatment options is required in order to allow timely diagnosis and appropriate treatment. Patients with prior major abdominal surgeries seem to be more prone to intestinal complications of reservoirs and warrant special concern. Cui T, Terlecki R, and Mirzazadeh M.

    Distal fibula fractures represent a common problem in orthopaedics. When fibula fractures require operative fixation, implants are typically made from stainless steel or titanium alloys. Carbon fiber implants have been used elsewhere in orthopaedics for years, and their advantages include a modulus of elasticity similar to that of bone, biocompatibility, increased fatigue strength, and radiolucency. This study hypothesized that carbon fiber plates would provide similar outcomes for ankle fracture fixation as titanium and steel implants. A retrospective chart review was performed of 30 patients who underwent fibular open reduction and internal fixation (ORIF). The main outcomes assessed were postoperative union rate and complication rate. The nonunion or failure rate for carbon fiber plates was 4% (1/24), and the union rate was 96% (23/24). The mean follow-up time was 20 months, and the complication rate was 8% (2/24). Carbon fiber plates are a viable alternative to metal plates in ankle fracture fixation, demonstrating union and complication rates comparable to those of traditional fixation techniques. Their theoretical advantages and similar cost make them an attractive implant choice for ORIF of the fibula. However, further studies are needed for extended follow-up and inclusion of larger patient cohorts. Level IV: Retrospective Case series.

    Autologous internal limiting membrane transplantation has allowed some cases of macular holes refractory to conventional surgery techniques to be treated. The purpose of this study is to describe the anatomical and functional outcomes of a modification of this technique in a case series of naïve macular hole patients. A consecutive case series study was performed on patients with naïve macular holes with a diameter greater than 600 μ. Best corrected visual acuity, clinical features of the macular area, and optical coherence tomography were recorded before the operation and at the end of follow-up in all patients studied. All patients underwent 23 Ga core vitrectomy, posterior hyaloid separation, and brilliant-blue assisted internal limiting membrane peeling. A small piece of the internal limiting membrane was peeled off to make a free flap, and this was trasplanted and placed inside the macular hole under perfluorocarbon liquids. Air-fluid exchange was performed and SF6 gas was injected at a non-expansile concentration. The study included 5 eyes of 5 patients who underwent internal limiting membrane autograft. The mean age was 50.6 (SD 12.3) years. Four of the 5 cases had macular hole closure. The case where there was no closure of the macular hole was secondary to trauma. There was an improvement in visual acuity in all patients where the closing of the macular hole was achieved at the end of follow-up. In this cases series of macular hole patients, the autologous internal limiting membrane transplantation was associated with an anatomical closure of the macular hole and functional improvement in most of the patients studied.

  4. KALREF—A Kalman filter and time series approach to the International Terrestrial Reference Frame realization

    The current International Terrestrial Reference Frame is based on a piecewise linear site motion model and realized by reference epoch coordinates and velocities for a global set of stations. Although linear motions due to tectonic plates and glacial isostatic adjustment dominate geodetic signals, at today's millimeter precisions, nonlinear motions due to earthquakes, volcanic activities, ice mass losses, sea level rise, hydrological changes, and other processes become significant. Monitoring these (sometimes rapid) changes desires consistent and precise realization of the terrestrial reference frame (TRF) quasi-instantaneously. Here, we use a Kalman filter and smoother approach to combine time series from four space geodetic techniques to realize an experimental TRF through weekly time series of geocentric coordinates. In addition to secular, periodic, and stochastic components for station coordinates, the Kalman filter state variables also include daily Earth orientation parameters and transformation parameters from input data frames to the combined TRF. Local tie measurements among colocated stations are used at their known or nominal epochs of observation, with comotion constraints applied to almost all colocated stations. The filter/smoother approach unifies different geodetic time series in a single geocentric frame. Fragmented and multitechnique tracking records at colocation sites are bridged together to form longer and coherent motion time series. While the time series approach to TRF reflects the reality of a changing Earth more closely than the linear approximation model, the filter/smoother is computationally powerful and flexible to facilitate incorporation of other data types and more advanced characterization of stochastic behavior of geodetic time series.

    With respect to the unknown aetiology of molar incisor hypomineralisation (MIH), it is unclear whether this phenomenon was overlooked in the last century as a result of a high number of caries in children or if this developmental disorder was not present until then. Therefore, this study determined the presence of MIH in historical dentitions and teeth. Dental remains from late medieval (n = 191, twelfth-sixteenth century, Regensburg, Germany), post-medieval (n = 33, sixteenth-eighteenth century, Passau, Germany) and modern age archaeological skeletal series (n = 99, nineteenth-twentieth century, Altdorf, Germany) were examined for MIH. In addition, linear enamel hypoplasia (LEH), diffuse opacities, hypoplasia and Turner's teeth were documented. MIH-related demarcated opacities or enamel breakdowns were found in only 15 (0.4 %) of the 3891 examined permanent teeth. Ten cases (3.1 %) from a total of 323 dentitions were classified as having MIH. In contrast, 98 individuals (30.3 %) showed LEH. Other enamel disorders were recorded in 64 individuals (19.8 %). With respect to the low number of affected dentitions and teeth, MIH most likely did not exist or was at least rarely present in the investigated archaeological case series. This study supports the hypothesis that MIH may be linked to contemporary living conditions or other health-related factors.

    Autoerythrocyte sensitization syndrome (Gardner Diamond syndrome or GDS) is a rare syndrome characterized by painful and spontaneous purpura commonly affecting adult women, and is mostly associated with psychiatric illness. Diagnosis is mainly based on clinical presentation, exclusion of other simulating diseases, and psychiatric evaluation. Only few cases have been reported till date. We report five cases of spontaneous purpura with a normal investigation profile, except for iron deficiency anemia in 1 patient, of which three had associated underlying psychiatric illness. Autoerythrocyte sensitization test was positive in all our cases. Patients presenting with painful bruises without significant medical history such as underlying bleeding disorder or drug history or history of trauma should be considered for autoerythrocyte sensitization syndrome, and managed accordingly. The present study is a case series of patients with characteristic features of autoerythrocyte sensitization syndrome, considering the rarity of the reports on its clinical spectra. PMID:29644197

    Kabuki syndrome is a rare hereditary disease affecting multiple organs. The causative genes identified to date are KMT2D and KDMA6. The aim of this study is to evaluate the clinical manifestations and the spectrum of mutations of KMT2D. We retrospectively retrieved a series of eight patients from two hospitals in China and conducted Sanger sequencing for all of the patients and their parents if available. We also reviewed the literature and plotted the mutation spectrum of KMT2D. The patients generally presented with typical clinical manifestations as previously reported in other countries. Uncommon symptoms included spinal bifida and Dandy-Walker malformation. With respect to the mutations, five mutations were found in five patients, including two frameshift indels, one nonsense mutation and two missense mutations. This is the first case series on Kabuki syndrome in Mainland China. Unusual symptoms, such as spinal bifida and Dandy-Walker syndrome, suggested that neurological developmental defects may accompany Kabuki syndrome. This case series helps broaden the mutation spectrum of Kabuki syndrome and adds information regarding the manifestations of Kabuki syndrome.

    Despite international notification requirements, the magnitude of disease transmission on board ships remains undetermined. This case series aims to exemplify that varicella aboard ships is a topic of interest for maritime medicine and of public health significance. Systematic presentation of cases of chickenpox reported to the Hamburg Port Health Authority between November 2007 and April 2008. A systematic literature search on 'ships and chickenpox' was performed. Five crew cases of chickenpox were reported from two passenger ships and two cargo ships. The cases originated from Indonesia (2), the Philippines (1), and Sri Lanka (2). Three cases were notified by the shipmaster, one by a general practitioner, and one by the immigration service. Sources of infection were other crewmembers, passengers, and persons in the home countries. This description of five varicella cases aboard ships points to the significance of the disease among seafarers. Many seafarers originate from tropical countries where seroconversion to varicella zoster virus generally occurs in late adolescents and adults. Thus, a substantial portion of the crew may be non-immune and have the potential to introduce the disease from their home country to the ship, or are at risk for infection on the ship. Port health authorities, shipmasters, and doctors need to be well informed about the relevance of chickenpox on ships and the recommended control measures. Travellers should be advised to report to the ship doctor with any signs of infectious disease.

    Review clinical experience with temporal fossa hemangiopericytomas (HPCs). Retrospective case series review. Tertiary referral center. Intracranial HPCs within the temporal fossa. Craniotomy for either subtotal or gross total tumor excision. Determination of clinical outcome (alive with no evidence of disease, alive with disease, and died of disease). Five cases of HPC involving the temporal fossa were treated at our tertiary referral center for the period from 1995 to 2008. All but 1 patient were men. The age of presentation ranged from 31 to 62 years, and duration of follow-up ranged from 8 to 153 months. Clinical presentation was protean; headache was the most common symptom. Gross total tumor excision was achieved in 2 patients, whereas subtotal tumor excision was achieved in 3 patients. Reasons for subtotal resection included excessive intraoperative blood loss and inextricable tumor. Histologically, all tumors were composed of tightly packed, randomly oriented (jumbled-up) tumor cells with little intervening collagen. CD34 staining mostly highlighted the vascular background. One patient died of disease, 2 patients were alive with disease, and 2 patients had no evidence of disease. Management of temporal fossa HPC is challenging because clinical presentation is often late, and extent of tumor excision is constrained by vital structures in the cranial base and intracranial contents. A multidisciplinary approach with neurosurgery and neurotology undertaken to achieve the most complete tumor resection possible, whereas minimizing morbidity are likely to confer a longer period of symptom-free survival and improves curability of these difficult lesions.

    Inflammatory pseudotumor (IP) is an uncommon idiopathic lesion that often imitates malignancy clinically and radiologically. Inflammatory pseudotumors have been found to occur in various sites but rarely in the head and neck. The histopathology, imaging, and treatment of three unique cases of head and neck inflammatory pseudotumors are described in this case series. Patients in Cases 1 and 2 presented with right level II neck mass and left parotid tail mass, respectively. The patient in Case 3 presented with otalgia, jaw pain and trismus, and a left parapharyngeal space mass. The tumors in Cases 1 and 3 significantly decreased in size with tapered courses of oral corticosteroids. The tumor in Case 2 was surgically excised without disease recurrence. Malignancy must be ruled out with incisional or excisional biopsy. Treatment includes surgical excision, oral corticosteroids, or both. The literature shows that radiotherapy and small-molecule inhibitors may be promising alternatives. PMID:27650653

    To determine the feasibility and safety of transverse fundal incision with manual placental removal in women with placenta praevia and possible placenta accreta. Case series. Four level-three Japanese obstetric centres. Thirty-four women with prior caesarean section and placenta praevia that widely covers the anterior uterine wall, in whom placenta accreta cannot be ruled out. A transverse fundal incision was performed at the time of caesarean section and manual placental removal was attempted under direct observation. Operative fluid loss. The total volume of fluid lost during our operative procedure compares favourably with the volume lost during our routine transverse lower-segment caesarean sections performed in patients without placenta praevia or accreta. The average fluid loss was 1370 g. No patients required transfer to intensive care, and there were no cases of fetal anaemia. This procedure has the potential to reduce the heavy bleeding that arises from caesarean deliveries in women with placenta praevia and placenta accreta. © 2013 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2013 RCOG.

    2015-01-01

    Abstract Introduction and Aim Complications related to inflatable penile prosthesis (IPP) and artificial urinary sphincter (AUS) reservoirs are rare, potentially life threatening, and poorly described in the literature. As more devices are implanted, the incidence of reservoir‐related complications may increase, and it will be important to recognize the relevant signs and symptoms. Methods and Main Outcome Measures We present a case series of reservoir‐related complications presenting to our institution for treatment. We also reviewed all accounts of reservoir‐related complications within the urologic literature Results Three cases of reservoir‐related complications are presented. Case 1 involves erosion of an intact AUS reservoir into the cecum of a patient with a history of myelomeningocele and bladder augmentation. Case 2 involves an IPP reservoir causing vascular compression, resulting in open exploration and repositioning of the reservoir. Case 3 involves intraperitoneal migration of a retained IPP reservoir to a subhepatic area, which was then removed laparoscopically. Literature review yielded descriptions of eight cases of intestinal complications, five cases of vascular complications, but zero reports of migration to a subhepatic area. Other notable complications include 20 reported cases of reservoir erosion into the bladder and inguinal herniation of the reservoir. Conclusion Complications involving urologic prosthesis reservoirs, although rare, can have serious implications for patients. A high index of suspicion and familiarity with treatment options is required in order to allow timely diagnosis and appropriate treatment. Patients with prior major abdominal surgeries seem to be more prone to intestinal complications of reservoirs and warrant special concern. Cui T, Terlecki R, and Mirzazadeh M.

    Opioids have narrow therapeutic windows, and errors in ordering or administration can be fatal. The purpose of this study was to describe deaths involving hydromorphone and morphine, which have similar-sounding names, but different potencies. In this case series, we describe deaths of patients admitted to hospital or residents of long-term care facilities that involved hydromorphone and morphine. We searched for deaths referred to the Patient Safety Review Committee of the Office of the Chief Coroner for Ontario between 2007 and 2012, and subsequently reviewed by 2014. We reviewed each case to identify intervention points where errors could have been prevented. We identified 8 cases involving decedents aged 19 to 91 years. The cases involved errors in prescribing, order processing and transcription, dispensing, administration and monitoring. For 7 of the 8 cases, there were multiple (2 or more) possible intervention points. Six cases may have been prevented by additional patient monitoring, and 5 cases involved dispensing errors. Opioid toxicity deaths in patients living in institutions can be prevented at multiple points in the prescribing and dispensing processes. Interventions aimed at preventing errors in hydromorphone and morphine prescribing, administration and patient monitoring should be implemented and rigorously evaluated.

    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 objectives of this report are, first, to describe the clinical behavior of cases of carcinoma metastatic to the uterine cervix treated at our institution in order to carry out a systematic review to establish the behavioral patterns of the most frequent metastases to the cervix and, second, to generate guidelines for their diagnosis and treatment. At the National Institute of Cancer of Mexico (INCan), we performed a review of the clinical files with a diagnosis of malignant neoplasm metastatic to the uterine cervix between 1990 and 2009. For a systematic review, we conducted a PubMed search between the years 1970 and 2009 of case reports and series of cases of patients with metastatic gastric, breast, ovarian and colorectal cancer. We analyzed each report individually and extracted the patients' clinical data from our cases and reports, including the primary tumor, cervical metastases and survival rates. There were 10 cases of tumors metastatic to the uterine cervix. Metastasis was documented in one-half of the patients during follow up, with two of these cases having the cervix as the only site. We included the following reports in the systematic review: 13 reports of gastric-associated cancer, 30 related to breast cancer, nine with ovarian-associated cancer and 10 related to colorectal cancer. Metastatic cervical activity is an infrequent event. The prognosis of survival is poor in the presence of gastric or ovarian cancer and cervical metastases. © 2012 The Authors.

    PubMed Central

    Poceta, J. Steven

    2011-01-01

    Study Objectives: To describe zolpidem-associated complex behaviors, including both daytime automatisms and sleep-related parasomnias. Methods: A case series of eight clinical patients and six legal defendants is presented. Patients presented to the author after an episode of confusion, amnesia, or somnambulism. Legal defendants were being prosecuted for driving under the influence, and the author reviewed the cases as expert witness for the defense. Potential predisposing factors including comorbidities, social situation, physician instruction, concomitant medications, and patterns of medication management were considered. Results: Patients and defendants exhibited abnormal behavior characterized by poor motor control and confusion. Although remaining apparently interactive with the environment, all reported amnesia for 3 to 5 hours. In some cases, the episodes began during daytime wakefulness because of accidental or purposeful ingestion of the zolpidem and are considered automatisms. Other cases began after ingestion of zolpidem at the time of going to bed and are considered parasomnias. Risk factors for both wake and sleep-related automatic complex behaviors include the concomitant ingestion of other sedating drugs, a higher dose of zolpidem, a history of parasomnia, ingestion at times other than bedtime or when sleep is unlikely, poor management of pill bottles, and living alone. In addition, similar size and shape of two medications contributed to accidental ingestion in at least one case. Conclusions: Sleep driving and other complex behaviors can occur after zolpidem ingestion. Physicians should assess patients for potential risk factors and inquire about parasomnias. Serious legal and medical complications can occur as a result of these forms of automatic complex behaviors. Citation: Poceta JS.

  19. Congenital asymptomatic diaphragmatic hernias in adults: a case series

    PubMed Central

    2013-01-01

    Introduction 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. Case presentations 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. Conclusions 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. PMID:23668793

    The coincidental occurrence of a cardiac symptomatology (e.g. an acute coronary syndrome or a myocardial infarction), during an anaphylactic or anaphylactoid episode is known as Kounis Syndrome. A variety of drugs, substances, food and environmental exposures are associated with this reaction. There is an exponential increase in the number of published scientific articles reports on this syndrome, but since it is rare, the largest case series published so far included only 10 and 6 patients. We searched the global World Health Organization database called VigiBase™ to detect all cases of Kounis Syndrome ever reported (last update December 31st 2014). We identified 51 cases of Kounis Syndrome reported to International Pharmacovigilance Agency (VigiBase™). All these cases were reported in the period 2010-2014 and almost half cases (22 reports) belonged to the year 2014. Most cases occurred in the USA and non-steroidal anti-inflammatory drugs were the most frequent trigger drugs. We collected pharmacovigilance international data representing the largest case series ever published on the recently identified Kounis Syndrome. Copyright © 2015 Elsevier Ireland Ltd.

    Neurosurgical disorders are rare during pregnancy and challenge the anesthesiologist with conflicting anesthetic considerations and little evidence to guide decision-making. Our objective was to review the anesthetic management of pregnant patients undergoing intracranial neurosurgery at our institution and to describe the perioperative complications and outcomes. We used our institutional Discharge Abstract Database to identify patients assigned both neurological and obstetrical International Classification of Disease 10-A codes between April 1, 2001 and March 1, 2012. Pregnant patients who underwent intracranial neurosurgical procedures underwent a detailed chart review to extract demographic data and details about their anesthetic management and outcome. Nine patients underwent full chart review with a median age of 28 (range, 17 to 35) years and a gestational age of 23 (range, 7 to 30) weeks. Patients underwent a craniotomy for vascular lesions (4), neoplasms (3), and traumatic brain injuries (2). One patient was hyperventilated (PaCO2 28 mmHg), and mannitol and furosemide were used in 6 and 3 patients, respectively, without complication. Maternal neurological outcomes were good in 5 patients (Glasgow Outcome Scale of >3), poor in 3 patients (Glasgow Outcome Scale 3), and 1 patient died. Fetal outcomes were good in 5 patients and poor in 4 patients (1 therapeutic abortion, 3 intrauterine fetal demises). All cases of fetal distress or demise were either remote or occurred before the anesthetic management. Pregnant patients undergoing neurosurgery experience a high rate of morbidity and mortality. There were no adverse outcomes directly attributed to the use of osmotic diuretics and hyperventilation in our series.

    The purpose of this case series is to describe the use of diagnostic ultrasound (US) in the detection of occult rib and costal cartilage fractures presenting as chest wall pain to a chiropractic clinic. Three patients presented with chest wall pain and tenderness. Two of the patients presented with acute chest wall injury and 1 carried a previous diagnosis of rib fracture after trivial trauma 2 months earlier. Diagnostic US was selected as a non-ionizing imaging tool for these patients after negative digital radiography studies. All fractures were considered isolated as there was no associated injury, such as pneumothorax. Both of the acute cases were followed up to complete healing (evidence of osseous union) using US. All patients eventually achieved pain-free status. In these cases, US was more sensitive than radiography for diagnosing these cases of acute rib and costal cartilage fractures. Early recognition of rib injury could avoid potential complications from local manipulative therapy.

    Masturbation is common in all societies. Despite being common, it is admonished culturally and almost all religions prohibit masturbation and consider it an act of immorality. The prohibition for masturbation leads to a lot of cultural beliefs, including certain myths, which influence sexual behavior of the person. The impact of these common cultural myths associated with masturbation, are clinically understood as Dhat syndrome and masturbatory guilt. Although there is a reasonable literature on Dhat syndrome, there is limited literature with regard to masturbatory guilt especially linking the same with axis-I psychopathology. In this case series, three cases of masturbatory guilt are presented in whom masturbatory guilt was associated with manifestation of severe psychopathology. This report suggests that masturbatory guilt must be enquired for in patients presenting with severe mental disorder. PMID:25722518

    Chronic migraines and tension-type headaches are debilitating diseases affecting 1.4 to 2.2% of the population with both quality of life and economic implications. To date, the pain associated with migraine and tension-type headaches has been controlled with a range of medications, with varying levels of success. In addition, the side-effect profile of these medications, as well as their potential for addiction, has been a cause for concern for both patients and physicians. Four women with long histories of migraine or frequent tension-type headache that meet the International Classification of Headache Disorders criteria for Chronic Migraine or Tension-type Headaches were given a systemic treatment(s) of autologous stromal vascular fraction or autologous 'StroMed' isolated from lipoaspirate. StroMed is stromal vascular fraction cells prepared by ultrasonic cavitation. Two of the four patients, both of whom are Arab women aged 40 and 36 years, ceased having migraines after 1 month, for a period of 12 to 18 months. The third patient, a Slavic woman aged 43 years, had a significant decrease in the frequency and severity of migraines with only seven migraines over 18 months. The fourth patient, an Asian woman aged 44 years, obtained a temporary decrease for a period of a month and was retreated 18 months later and has been free of migraines to date for 1 month. Pain medication was typically reduced from prescribed opioid analgesia to non-steroidal anti-inflammatory drugs and paracetamol. This case series is the first to provide evidence of the efficacy of autologous StroMed and stromal vascular fraction in the treatment of migraine and tension-type headache. The treatment of this disease by stromal vascular fraction adds a new dimension to its clinical applicability and suggests a relatively simple treatment that may help address the symptoms of the disease. Given what is known about the components of the stromal vascular fraction and how they act, the information

    The novel concept explored in this case series is the primacy of headaches in generating seizures in those patients who suffer from migraine-triggered epilepsy. In this series, once the migraine headaches were fully suppressed, via daily scheduled opioid therapy, the seizures also stopped. Seizures returned, however, after the patients stopped the opiate regimen for any reason. The above pharmacological scenario is reminiscent of a similar but naturalistic course of events reported on the salutary effects of ketogenic diet, or changes in life style, in similar cases of migraine-triggered epilepsy. The primacy of migraine in treating what has been named ‘seizure headaches’ is seen in two other scenarios (i.e. the salutary effect of ketogenic diet and lifestyle changes resulting in restoration of one’s sleeping pattern) thus stopping the migraine as well as the seizures associated with the same. This case series recounts the same phenomenon via utilizing around-the-clock maintenance opioid therapy. PMID:28203347

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

    Abstract: With an increasing number of off-pump coronary artery surgery procedures in high-risk patients with coagulopathy, including renal failure, hepatic failure and anticoagulant drug-using patients, the frequency of related complications such as repeated exploration for bleeding is also increasing. The associated co-morbidity and repeated use of electrocautery in postoperative bleeding leaves patients susceptible to electrocautery ulcers. In this case series, rare cases of cautery burn with unique causative mechanisms are described. PMID:23669602

    We describe a family Therapeutic Assessment (TA) case study employing 2 assessors, 2 assessment rooms, and a video link. In the study, we employed a daily measures time-series design with a pretreatment baseline and follow-up period to examine the family TA treatment model. In addition to being an illustrative addition to a number of clinical reports suggesting the efficacy of family TA, this study is the first to apply a case-based time-series design to test whether family TA leads to clinical improvement and also illustrates when that improvement occurs. Results support the trajectory of change proposed by Finn (2007), the TA model's creator, who posits that benefits continue beyond the formal treatment itself.

    To report a case series of ischemic gastritis and discuss its etiology, management, and associated mortality according to our results and the published English literature. Ischemic gastritis is rare, given the rich blood supply of the stomach. It has been reported in isolated case reports and small case series. Most cases are vascular in origin and associated with a high mortality. Pathology databases from 3 hospitals affiliated with the University of Minnesota Medical School were searched for cases of ischemic gastritis in the last 10 years. Patients' demographics, clinical course, and 1-month and 1-year mortalities were collected from electronic medical records. A total of 12 patients were identified (age range, 32.1 to 83.2), the largest series reported to date. The presenting symptom was gastrointestinal bleeding (8), abdominal pain (2), nausea (1), and symptomatic anemia (1). The etiology included postinterventional radiology embolization (2), hemodynamic changes in the setting of celiac axis stenosis (2), vasculitis (1), systemic hypotension (1), and unknown (6). Treatment included steroid therapy, revascularization by interventional radiology, surgery, or supportive treatment. Thirty-day and 1-year mortalities were 33% and 41%, respectively. Ischemic gastritis is rare, but associated with a high mortality. Evaluation for treatable etiologies should be sought and corrected if present.

    Q fever is a global zoonosis that can cause both acute and chronic infections in humans through aerogenic transmission. Although Q fever was discovered already 80 years ago, this infectious disease remains largely unknown. We studied a case series in a Belgian tertiary care hospital. A laboratory and file query at our department was performed to detect patients who were newly diagnosed with Q fever from 01 January 2005 to 01 October 2014. In total, 10 acute Q fever and 5 chronic Q fever infections were identified. An aspecific flu-like illness was the prevailing manifestation of acute Q fever, while this was infective endocarditis in chronic Q fever cases. Noteworthy are the high percentage of myocarditis cases in the acute setting and one case of amyloidosis as a manifestation of chronic Q fever. No evolution from acute to chronic Q fever was noted; overall outcome for both acute and chronic Q fever was favourable with a 94% survival rate. Q fever is an infectious disease characterised by a variable clinical presentation. Detection requires correct assessment of the clinical picture in combination with a laboratory confirmation. Treatment and follow-up are intended to avoid a negative outcome.

  16. Quality in translation: case management in the international marketplace.

    2009-01-01

    This article identifies three categories of case management (CM), in-country, international, and micro, that are poised to serve as the quality proxy for the international medical patient in the rapidly emerging globalized healthcare marketplace. The content concentrates on describing in-country CM and international CM (ICM). Because CM professionals are the providers of patient-centered quality and safety improvements, they are capable of filling the chasm between the travel industry and the regulators who specialize in accrediting hospital systems. In-country and ICM case managers are equipped to perform surveillance and intervention at the level of the international patient's bedside, activate network connections, and use culture-sensitive communication skills to safeguard patients in their individual sojourns abroad. The article discusses useful concepts and sources, including an algorithmic tool under development that is geared to identify and quantify risks for lay and business individuals who seek to engage the global medical market. The article's information is provided for front-line and front-office healthcare practitioners to understand or enter the worldwide medical marketplace. Content is targeted to CM generalists, specialists, and business developers interested in learning about safeguarding the patients who travel internationally to receive medical care. It can also be applied by those within and outside the healthcare practice arena, particularly those interested in the development of quality initiatives. All research and syntheses were executed by the authors. Sources included scholarly treatises, business correspondence, medical tourism literature, corporate Internet profiles, news releases, and healthcare industry investigative and monitoring agencies. International health insurance, economics, and financing expertise stems from one author (L.B.). Clinical competencies stem from the international practice experiences of one author (K.C.). This

    2013-02-01

    Nasopharyngeal branchial cysts (NBCs) have been discussed in the literature in only a limited number of publications. Differing from Tornwaldt cysts, NBCs present laterally and arise from the fossa of Rosenmuller and may track superiorly within the bony confines of the Eustachian tube. Initially patients are asymptomatic but may present with aural fullness, unilateral conductive hearing loss, and serous otitis media as the cyst mass grows. Two of our three patients had the lesion incidentally identified at the time of assessment for another diagnosis. In this case series, imaging characteristics and response to treatment are reviewed. A literature search was performed to summarize the management options for this entity.

    Psychogenic dysphonia is a functional disorder with variable clinical manifestations. To assess the clinical and vocal characteristics of patients with psychogenic dysphonia in a case series. The study included 28 adult patients with psychogenic dysphonia, evaluated at a University hospital in the last ten years. Assessed variables included gender, age, occupation, vocal symptoms, vocal characteristics, and videolaryngostroboscopic findings. 28 patients (26 women and 2 men) were assessed. Their occupations included: housekeeper (n=17), teacher (n=4), salesclerk (n=4), nurse (n=1), retired (n=1), and psychologist (n=1). Sudden symptom onset was reported by 16 patients and progressive symptom onset was reported by 12; intermittent evolution was reported by 15; symptom duration longer than three months was reported by 21 patients. Videolaryngostroboscopy showed only functional disorders; no patient had structural lesions or changes in vocal fold mobility. Conversion aphonia, skeletal muscle tension, and intermittent voicing were the most frequent vocal emission manifestation forms. In this case series of patients with psychogenic dysphonia, the most frequent form of clinical presentation was conversion aphonia, followed by musculoskeletal tension and intermittent voicing. The clinical and vocal aspects of 28 patients with psychogenic dysphonia, as well as the particularities of each case, are discussed.

  19. Internal and External Reconnection Series Homologous Solar Flares

    NASA Technical Reports Server (NTRS)

    Sterling, Alphonse C.; Moore, Ronald L.

    2001-01-01

    Using data from the extreme ultraviolet imaging telescope (EIT) on SOHO and the soft X-ray telescope (SXT) on Yohkoh, we examine a series of morphologically homologous solar flares occurring in National Oceanic and Atmospheric Administration (NOAA) active region 8210 over May 1-2, 1998. An emerging flux region (EFR) impacted against a sunspot to the west and next to a coronal hole to the east is the source of the repeated flaring. An SXT sigmoid parallels the EFR's neutral line at the site of the initial flaring in soft X rays. In EIT each flaring episode begins with the formation of a crinkle pattern external to the EFR. These EIT crinkles move out from, and then in toward, the EFR with velocities approx. 20 km/ s. A shrinking and expansion of the width of the coronal hole coincides with the crinkle activity, and generation and evolution of a postflare loop system begins near the time of crinkle formation. Using a schematic based on magnetograms of the region, we suggest that these observations are consistent with the standard reconnection-based model for solar eruptions but are modified by the presence of the additional magnetic fields of the sunspot and coronal hole. In the schematic, internal reconnection begins inside of the EFR-associated fields, unleashing a flare, postflare loops, and a coronal mass ejection (CME). External reconnection, first occurring between the escaping CME and the coronal hole field and second occurring between fields formed as a result of the first external reconnection, results in the EIT crinkles and changes in the coronal hole boundary. By the end of the second external reconnection, the initial setup is reinstated; thus the sequence can repeat, resulting in morphologically homologous eruptions. Our inferred magnetic topology is similar to that suggested in the "breakout model" of eruptions although we cannot determine if our eruptions are released primarily by the breakout mechanism (external reconnection) or, alternatively

    Lymphogranuloma venereum (LG) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis L serovar. These five consecutive cases aim to highlight the risk of LG misdiagnosis, in case of initial presentation with isolated inguinal adenitis. Five men (mean age: 30±7 years) were seen in an internal medicine department, for inguinal adenopathy. One patient had clinical signs of urethritis. None presented an associated rectitis. Three patients had a history of STI, and two had a discovery of related HIV disease. Urinary polymerase chain reaction (PCR) was positive for the symptomatic patient and negative for the others. Lymph node PCR was positive in all patients within a L2b serotype (searched in 4 out of 5 cases). LG should be evoked in any patient with inguinal adenomegaly, particularly in case of STI history or risk factors. Negativity of urinary PCR should lead to further investigations, essentially a lymph node cytopuncture to evidence C. trachomatis.

    Psychosis in the context of multiple sclerosis (MS) has previously been reported as a rare occurrence. However, recent epidemiological studies have found prevalence rates of psychosis in MS that are two to three times higher than those in the general population. Untreated psychosis in patients with MS can adversely impact on adherence to MS medication, levels of disability, and quality of life. This retrospective case series describes the spectrum of psychotic disorders occurring in association with MS using demographic, clinical, and neuroimaging data. In the discussion, we highlight the particular diagnostic and treatment challenges that such disorders can pose for clinicians and through our case vignettes provide examples of potential interventions for this complex patient population.

    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.

    Although fortunately very rare in countries with a temperate climate, certain factors, such as clinical or pharmacological immunosuppression, may cause Fusarium-related fungal infections to become an emerging problem. Moreover, Fusarium is one of the most important etiological agents in exogenous endophthalmitis, which is often favored by the disruption of the epithelial barriers. The aim of this series of clinical cases is to identify characteristic clinical findings that may allow an early diagnosis and more efficient management of this ophthalmologic emergency. Three cases of endophthalmitis due to Fusarium solani and Fusarium oxysporum, diagnosed in 2009, 2010, and 2014 in patients from two different health regions belonging to the same health system and separated by around 43 miles, are presented. The Fusarium isolates were initially identified microscopically and the species subsequently confirmed by sequencing the elongation factor alpha (EFα) and internal transcribed spacers (ITS). Susceptibility to antifungal agents was determined using the EUCAST broth dilution method. Evolution was poor as two of the three patients progressed to phthisis bulbi despite surgical measures and broad-spectrum antifungal antibiotic therapy. It is essential to rapidly instigate multidisciplinary measures to combat suspected endophthalmitis due to Fusarium given the poor prognosis of this type of infection.

    THE CONCEPT OF FIBROOSSEOUS LESIONS OF BONE HAS EVOLVED OVER THE LAST SEVERAL DECADES AND NOW INCLUDES TWO MAJOR ENTITIES: fibrous dysplasia and ossifying fibroma. Peripheral cemento-ossifying fibroma is a relatively rare tumour classified between fibroosseous lesions. It predominantly affects adolescents and young adults, with peak prevalence between 10 and 19 yrs. The cemento-ossifying fibroma is a central neoplasm of bone as well as periodontium which has caused considerable controversy because of confusion regarding terminology and the criteria for its diagnosis. The cemento-ossifying fibroma is odontogenic in origin, whereas ossifying fibroma is of bony origin. Lesions histologically similar to peripheral ossifying fibroma have been given various names in existing literature. Therefore, we present and discuss in this paper a series of cases of peripheral cemento-ossifying fibroma emphasizing the differential diagnosis.

    Background: Opioids have narrow therapeutic windows, and errors in ordering or administration can be fatal. The purpose of this study was to describe deaths involving hydromorphone and morphine, which have similar-sounding names, but different potencies. Methods: In this case series, we describe deaths of patients admitted to hospital or residents of long-term care facilities that involved hydromorphone and morphine. We searched for deaths referred to the Patient Safety Review Committee of the Office of the Chief Coroner for Ontario between 2007 and 2012, and subsequently reviewed by 2014. We reviewed each case to identify intervention points where errors could have been prevented. Results: We identified 8 cases involving decedents aged 19 to 91 years. The cases involved errors in prescribing, order processing and transcription, dispensing, administration and monitoring. For 7 of the 8 cases, there were multiple (2 or more) possible intervention points. Six cases may have been prevented by additional patient monitoring, and 5 cases involved dispensing errors. Interpretation: Opioid toxicity deaths in patients living in institutions can be prevented at multiple points in the prescribing and dispensing processes. Interventions aimed at preventing errors in hydromorphone and morphine prescribing, administration and patient monitoring should be implemented and rigorously evaluated. PMID:28401133

    The definition of neuropathic pain has recently been revised by an expert committee of the Neuropathic Pain Special Interest Group of the International Association for the Study of Pain (NeuPSIG) as "pain arising as direct consequence of a lesion or disease affecting the somatosensory system," and a grading system of "definite," "probable," and "possible" neuropathic pain has been introduced. This open case series of 5 outpatients (3 men, 2 women; mean age 48 +/- 12 years) demonstrates how the grading system can be applied, in combination with appropriate confirmatory testing, to diagnosis neuropathic conditions in clinical practice. The proposed grading system includes a dynamic algorithm that enhances the physician's ability to determine with a greater level of certainty whether a pain condition is neuropathic. Its clinical use should be further validated in prospective studies.

    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.

    AbstractThe incidence of hepatitis E in Singapore appears to be increasing. A retrospective case-series study of patients diagnosed with hepatitis E in a tertiary hospital from 2009 to 2013 was conducted. Of 16 cases, eight (50%) were solid-organ transplant recipients (SOTRs), and 14 (88%) were found infected by genotype 3 hepatitis E virus (HEV-3). Bayesian inferences based on HEV subgenomic sequences from seven cases suggest that HEV-3 strains were introduced to Singapore as two principal lineages. Within limitations of the study, it can be inferred that one lineage, in the 3efg clade, emerged about 83 years ago, probably originating from Japan, whereas the other, in the 3abchij clade, emerged about 40 years ago, from the United States. Establishment and subsequent transmissions of strains from these two lineages likely contribute to the current endemicity of hepatitis E in Singapore.

    Thorough understanding of the anatomic and internal morphology of a root canal system is absolutely essential for the success of endodontic treatment. Since permanent maxillary first molars have shown variation in internal anatomy, morphology, this tooth has been reviewed extensively. Presence of two canals in a two-rooted maxillary first molar has rarely been reported in studies describing tooth and root canal anatomies. In this report, three cases are presented, which involve the root canal treatment of maxillary first molars with fusion of the two buccal roots.

    Case series. Plantar flexion/inversion ankle sprains are one of the most frequently occurring sports injuries. Cuboid syndrome, which is difficult to diagnose, may result from a plantar flexion/ inversion ankle injury and could become the source of lateral ankle/midfoot pain. The objective of this case series is to describe the examination, evaluation, and treatment of the cuboid syndrome following a lateral ankle sprain. Seven patients were seen in our clinic 1 to 8 weeks following a lateral ankle sprain with a chief complaint of lateral ankle/midfoot pain. In these 7 patients, the presence of cuboid syndrome was identified independently by 2 examiners. Treatment consisted of a cuboid manipulation. All 7 patients returned to sports activities following 1 to 2 treatments consisting of the "cuboid whip" manipulation. No recurrence of symptoms was reported upon immediate return to competition or during the remainder of the season (mean follow-up, 5.7 months; range, 2 to 8 months). Based on those 7 patients, our results suggest that patients who are properly diagnosed with cuboid syndrome and receive the cuboid manipulation can return to competitive activity within 1 or 2 visits without injury recurrence.

    The optimal therapeutic approach for adult craniopharyngioma remains controversial. Some advocate for gross total resection (GTR), while others advocate for subtotal resection followed by adjuvant radiotherapy (STR + XRT). To conduct a systematic review and meta-analysis assessing the rate of recurrence in the follow-up of 3 yr in adult craniopharyngioma stratified by extent of resection and presence of adjuvant radiotherapy. MEDLINE (1946-July 1, 2016) and EMBASE (1980-June 30, 2016) were systematically reviewed. From1975 to 2013, 33 patients were treated with initial surgical resection for adult onset craniopharyngioma at our center and were reviewed for inclusion in this study. Data from 22 patients were available for inclusion as a case series in the systematic review. Eligible studies (n = 21) were identified from the literature in addition to a case series of our institutional experience. Three groups were available for analysis: GTR, STR + XRT, and STR. The rates of recurrence were 17%, 27%, and 45%, respectively. The risk of developing recurrence was significant for GTR vs STR (odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.15-0.38) and STR + XRT vs STR (OR: 0.20, 95% CI: 0.10-0.41). Risk of recurrence after GTR vs STR + XRT did not reach significance (OR: 0.63, 95% CI: 0.33-1.24, P = .18). This is the first and largest systematic review focusing on the rate of recurrence in adult craniopharyngioma. Although the rates of recurrence are favoring GTR, difference in risk of recurrence did not reach significance. This study provides guidance to clinicians and directions for future research with the need to stratify outcomes per treatment modalities. Copyright © 2017 by the Congress of Neurological Surgeons

  17. Epilepsy and violence: case series concerning physical trauma in children of persons with epilepsy

    Gauffin, Helena; Landtblom, Anne-Marie

    2014-01-01

    Historically, epilepsy has been associated with violence, but more recent studies have emphasized genetic and psychosocial factors as more important. The case series presented here aim to highlight the difficult situation the affected children are in. We report on three cases when children have been traumatized and, in one case, even been killed by their parent who was diagnosed with epilepsy. In the first case, we describe a woman with juvenile myoclonic epilepsy who was sentenced to forensic psychiatry care for killing her child. She lived under difficult psychosocial circumstances and a suicide attempt contributed to what happened. The second case describes a man with post-traumatic seizures who was sentenced for child abuse. Ictal or postictal violence was considered in these two cases but a causal link between the violence and epilepsy has not been established. In the third case, we describe a woman with focal epilepsy and psychogenic non-epileptic seizures (PNESs). Her child was hurt and frightened in relation to violent seizures, which were regarded as PNESs. This case series demonstrates that children of parents with epilepsy can be in a vulnerable situation. No causality has been established between the seizures and these events, so consequently other factors such as psychosocial stress, low cognitive function, and a suicide attempt must also be considered as important. When a child is hurt by a parent with epilepsy the patient must be closely examined to determine the role of the seizures. Children can also be affected by PNESs. It is essential to notice especially those children of parents with epilepsy who live under difficult psychosocial circumstances and offer extra support when necessary. PMID:25484586

    2012-01-01

    Cemento-ossifying fibroma is a benign fibro-osseous lesion belonging to the same category as fibrous dysplasia and cementifying dysplasia. These are slow-growing lesions that are seen in the third and fourth decades of life. Both the ossifying fibroma and cemento-ossifying fibroma represent two extremes of the same disease process since histologically both contain bone and cementum. However, the term cemento-ossifying fibroma is justified on the basis of clinical and radiological correlation. Radiographs have become an essential tool in the diagnosis of lesions in the jaw, where the anatomy is complex. Nowadays, CT provides information for diagnosis as well as treatment planning. In this case series, we report three cases of cemento-ossifying fibroma that were histologically confirmed and discuss the imaging findings.

    Study Design Case series. Background Although growing recognition of cervicogenic dizziness (CGD) is emerging, there is still no gold standard for the diagnosis of CGD. The purpose of this case series is to describe the clinical decision making utilized in the management of 7 patients presenting with CGD. Case Description Patients presenting with neck pain and accompanying subjective symptoms, including dizziness, unsteadiness, light-headedness, and visual disturbance, were selected. Clinical evidence of a temporal relationship between neck pain and dizziness, with or without sensorimotor disturbances, was assessed. Clinical decision making followed a 4-step process, informed by the current available best evidence. Outcome measures included the numeric rating scale for dizziness and neck pain, the Dizziness Handicap Inventory, Patient-Specific Functional Scale, and global rating of change. Outcomes Seven patients (mean age, 57 years; range, 31-86 years; 7 female) completed physical therapy management at an average of 13 sessions (range, 8-30 sessions) over a mean of 7 weeks. Clinically meaningful improvements were observed in the numeric rating scale for dizziness (mean difference, 5.7; 95% confidence interval [CI]: 4.0, 7.5), neck pain (mean difference, 5.4; 95% CI: 3.8, 7.1), and the Dizziness Handicap Inventory (mean difference, 32.6; 95% CI: 12.9, 52.2) at discontinuation. Patients also demonstrated overall satisfaction via the Patient-Specific Functional Scale (mean difference, 9) and global rating of change (mean, +6). Discussion This case series describes the physical therapist decision making, management, and outcomes in patients with CGD. Further investigation is warranted to develop a valid clinical decision-making guideline to inform management of patients with CGD. Level of Evidence Diagnosis, therapy, level 4.

    Hindfoot arthroscopic surgery has been described as a minimally invasive surgical treatment for posterior ankle impingement syndrome. The current article describes a systematic approach for identifying relevant hindfoot structures as well as the clinical results of a case series. To present a structured systematic surgical approach for identifying relevant anatomic structures and abnormalities during hindfoot arthroscopic surgery. In addition, we report the clinical results of a case series. Case series; Level of evidence, 4. The systematic surgical approach divides the extra-articular structures of the hindfoot into quadrants as defined by the intermalleolar ligament. Twenty-two patients underwent hindfoot arthroscopic surgery for the treatment of posterior ankle impingement syndrome. The mean follow-up time was 25 months (range, 14-35 months). Standard patient-reported outcome questionnaires of the foot and ankle outcome score (FAOS) and Short Form-12 (SF-12) general health survey were administered at standard time points after surgery. Return to sporting activities was also calculated as the time period from the date of surgery until the patient was able to participate at their previous level of activity. The mean FAOS score improved from 59 (range, 22-94) preoperatively to 86 (range, 47-100) postoperatively (P < .01). The mean SF-12 score showed similar improvement with a mean of 66 (range, 42-96) preoperatively to 86 (range, 56-98) postoperatively (P < .01). Nineteen patients reported competing at some level of athletic sport before surgery. All patients returned to their previous level of competition after surgery. The mean time to return to sporting activities was 12 weeks (range, 6-16 weeks). Two complications were reported postoperatively: 1 wound infection and 1 case of dysesthesia of the deep peroneal nerve. Hindfoot arthroscopic surgery is a safe and effective treatment strategy for posterior ankle impingement syndrome. In addition, it allows the

    The aim of this small case series is to describe four cases of severe mania, where ultrabrief pulse electroconvulsive therapy (ECT) was used as a primary mode of treatment. A retrospective file review was undertaken of four patients identified as having received ultrabrief pulse ECT for severe mania. The outcome measures for treatment efficacy were the Young Mania Rating Scale (YMRS) and Clinical Global Impression (CGI). All the patients showed significant clinical improvement. A comparison of pre- and post-treatment YMRS and CGI scores showed a dramatic decrease in all four cases. However, one patient was shifted to brief pulse ECT due to inadequate response. Ultrabrief pulse ECT may be an effective treatment in cases of severe mania. Due to the very small number of cases in the current case series, no specific conclusions regarding efficacy may be drawn; however, larger, controlled studies would be indicated.

    Marine carbonate system monitoring programs often consist of multiple observational methods that include underway cruise data, moored autonomous time series, and discrete water bottle samples. Monitored parameters include all, or some of the following: partial pressure of CO2 of the water (pCO2w) and air, dissolved inorganic carbon (DIC), total alkalinity (TA), and pH. Any combination of at least two of the aforementioned parameters can be used to calculate the others. In this study at the Gray's Reef (GR) mooring in the South Atlantic Bight (SAB) we: examine the internal consistency of pCO2w from underway cruise, moored autonomous time series, and calculated from bottle samples (DIC-TA pairing); describe the seasonal to interannual pCO2w time series variability and air-sea flux (FCO2), as well as describe the potential sources of pCO2w variability; and determine the source/sink for atmospheric pCO2. Over the 8.5 years of GR mooring time series, mooring-underway and mooring-bottle calculated-pCO2w strongly correlate with r-values > 0.90. pCO2w and FCO2 time series follow seasonal thermal patterns; however, seasonal non-thermal processes, such as terrestrial export, net biological production, and air-sea exchange also influence variability. The linear slope of time series pCO2w increases by 5.2 ± 1.4 μatm y-1 with FCO2 increasing 51-70 mmol m-2 y-1. The net FCO2 sign can switch interannually with the magnitude varying greatly. Non-thermal pCO2w is also increasing over the time series, likely indicating that terrestrial export and net biological processes drive the long term pCO2w increase.

    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.

    OASIS Ultra (Smith and Nephew, St. Petersburg, FL) is an extracellular, collagen-rich matrix derived from submucosa of porcine intestine. It is composed of collagen type I, glycosaminoglycan, and proteoglycans. This extracellular matrix (ECM) differs from the single layer in thickness and offers ease of handling and application. It also stimulates cell migration and structural support, provides moisture environment, decreases inflammation, and induces cell proliferation and cellular attachments. In this case series, the authors present their experience with this product in various clinical scenarios. The authors used the product in a variety of wounds with different etiologies to test the clinical outcome of the ECM. This was an observational case series with prospective review of 6 different patients with different types of wounds who received treatment with the ECM during their treatment. The product was applied on the following types of wounds: chronic venous ulcer, nonhealing Achilles tendon vasculitic wound, Marjolin's ulcer, posttraumatic wound, stage IV sacral-coccygeal pressure wound, and complicated transmetatarsal amputation of gangrenous left forefoot diabetic wound. All of these wounds healed within the expected time periods and without complications. In general, healing was achieved in 4-16 weeks using 1-12 applications of the ECM. Wounds with different etiologies were successfully treated with an extracellular, collagen-rich matrix. By replacing the lost ECM to guide cellular growth and migration, this product did ultimately hasten the healing process.

    This is the second of a 2-part primer on the genetics of the epilepsies within the Genetic Literacy Series of the Genetics Commission of the International League Against Epilepsy. In Part 1, we covered types of genetic variation, inheritance patterns, and their relationship to disease. In Part 2, we apply these basic principles to the case of a young boy with epileptic encephalopathy and ask 3 important questions: (1) Is the gene in question an established genetic etiology for epilepsy? (2) Is the variant in this particular gene pathogenic by established variant interpretation criteria? (3) Is the variant considered causative in the clinical context? These questions are considered and then answered for the clinical case in question. Wiley Periodicals, Inc. © 2018 International League Against Epilepsy.

    Tubal sterilisation using Essure is a minimally invasive technique for permanent contraception, with high rates of patient satisfaction. However, some women subsequently choose removal of the inserts, due to side effects such as pelvic pain, abnormal bleeding, dyspareunia or allergic dermatitis. This case series presents the management of eight women who underwent laparoscopic removal of Essure inserts in conjunction with salpingectomy. We describe our surgical technique, its underlying principles and immediate surgical outcomes. Eight patients were identified as having undergone removal of Essure inserts, via an electronic search of the surgical procedures database. A retrospective review of case records was undertaken. The primary outcome was safety and feasibility of the laparoscopic salpingectomy approach. Secondary outcome measures included implant fracture rate, operative time, blood loss and length of patient stay. All eight women were able to undergo laparoscopic salpingectomy and removal of the Essure inserts without the need for laparotomy or hysterectomy. There were no incidences of fracture or incomplete removal of the insert. Immediate postoperative recovery was uncomplicated in all eight women; the mean length of stay was 17 h. One patient had a small bowel serosal tear attributed to laparoscopic entry. This case series suggests that laparoscopic salpingectomy for removal of Essure inserts is safe and feasible. We acknowledge that the numbers were small. However, consistent use of a laparoscopic approach in these eight patients indicates that this procedure is a feasible and suitable alternative to hysterectomy.

    The concept of fibroosseous lesions of bone has evolved over the last several decades and now includes two major entities: fibrous dysplasia and ossifying fibroma. Peripheral cemento-ossifying fibroma is a relatively rare tumour classified between fibroosseous lesions. It predominantly affects adolescents and young adults, with peak prevalence between 10 and 19 yrs. The cemento-ossifying fibroma is a central neoplasm of bone as well as periodontium which has caused considerable controversy because of confusion regarding terminology and the criteria for its diagnosis. The cemento-ossifying fibroma is odontogenic in origin, whereas ossifying fibroma is of bony origin. Lesions histologically similar to peripheral ossifying fibroma have been given various names in existing literature. Therefore, we present and discuss in this paper a series of cases of peripheral cemento-ossifying fibroma emphasizing the differential diagnosis. PMID:23365762

    The most feared bleeding complication in fetal and neonatal alloimmune thrombocytopenia (FNAIT) is an intracranial hemorrhage (ICH). However, FNAIT may also lead to other severe bleeding problems. The aim was to analyze this spectrum and evaluate the occurrence of severe hemorrhages other than ICH in fetuses or neonates with FNAIT. A retrospective chart analysis of cases of FNAIT presenting with severe bleeding complications other than ICH at our institution from 1990 to 2015 was conducted. Additionally, a review of the literature was performed to identify case reports and case series on FNAIT presenting with extracranial hemorrhage. Of 25 fetuses or neonates with severe bleeding due to FNAIT, three had isolated severe internal organ hemorrhage other than ICH, two pulmonary hemorrhages and one gastrointestinal hemorrhage. Two of these three neonates died due to this bleeding. Eighteen cases of extracranial bleeding complications as a first presentation of FNAIT were found in the literature, including ocular, gastrointestinal, spinal cord, pulmonary, renal, subgaleal, and genitourinary hemorrhages. Bleeding complications other than ICH may be more extensive, and the presentation of FNAIT may have a greater spectrum than previously described. A high index of suspicion on the possible diagnosis of FNAIT with any bleeding complication in a fetus or neonate may enable adequate diagnostics, adequate treatment, and appropriate follow-up in future pregnancies, as is especially relevant for FNAIT. © 2016 AABB.

    Prospective case series. The purpose of this case series was to describe the criteria used to determine if patients were to receive slump stretch treatment within a treatment-based classification system and to describe selected symptom characteristics associated with these patients. Previous reports from the literature suggest that the slump test position may be a useful treatment and evaluation technique. However, little information has been presented regarding how to identify patients who are appropriate to treat with slump stretching and the symptom characteristics associated with these patients. Prior to recruitment, criteria were established to identify patients who would be considered appropriate to treat with slump stretching. Consecutive patients referred with low back diagnosis or low-back-related diagnoses were then evaluated using a treatment-based classification system. Selected symptom characteristics were collected from patients treated with slump stretching. Out of 88 consecutive patients with low back diagnoses or low-back-related diagnoses, 6 met the study's inclusion criteria and were treated with slump stretching. All pain diagrams were classified as "organic" or "possibly organic," and the most common symptom descriptor was "deep ache." At the discharge session of physical therapy, 5 of 6 patients had symptoms that were more proximally located and all patients reported a decrease in symptom intensity. Favorable changes in symptom intensity and location were observed for this case series, but definitive conclusions cannot be drawn from this study design. Additional research needs to be completed to determine if the slump test position is an effective evaluation and treatment technique.

    Reporting a special clinical finding after intravitreal bevacizumab monotherapy for retinopathy of prematurity. In a retrospective case series, the clinical courses of five premature infants with similar vitreous changes after a single dose of intravitreal bevacizumab (IVB) injection without additional laser therapy were reported. The mean post-conceptional age at IVB injection was 39.8 ± 2.2 (range 37-43) weeks. Localized vitreous syneresis and linear fibrotic vitreous condensation occurred 8.2 ± 2.3 weeks after IVB monotherapy in our patients (15.5% of injections). The mean last post injection visit was 61.6 ± 5.3 weeks (post-conceptional age). Further regression and complete retinal vascularization occurred in all patients. Thread-like vitreous condensation with localized vitreous liquefaction may be related to involutional ROP disease itself, combined to anti VEGF therapy and may be a predictor factor for further regression and retinal vascularization. The case series describes a successful response to anti-VEGF monotherapy with no further complications.

    Neuroendocrine tumors (NET) of the cervix are rare tumors with a very aggressive course. The human papillomavirus (HPV) has been linked to its etiology. The objective of this study is to describe HPV prevalence and genotype distribution of NET. Forty-nine tumors with histological neuroendocrine features were identified among 10,575 invasive cervical cancer (ICC) cases from an international study. HPV DNA detection was done using SPF10/DEIA /LiPA 25 system. Immunohistochemical (IHC) staining for neuroendocrine markers (chromogranin A, synaptophysin, CD56) and for p16 INK4a as a surrogate for HPV transforming infection was performed. In 13 samples with negative IHC for all 3 neuroendocrine markers studied, it was possible to conduct electron microscopy (EM). NET represented 0.5% of the total ICC series and HPV was detected in 42 out of 49 samples (85.7%, 95%CI:72.8%,94.1%). HPV16 was the predominant type (54.8%), followed by HPV18 (40.5%). p16 INK4a overexpression was observed in 38/44 cases (86.4%). Neuroendocrine IHC markers could be demonstrated in 24/37 (64.9%) cases. EM identified neuroendocrine granules in 8 samples with negative IHC markers. Our data confirms the association of cervical NET with HPV and p16 INK4a overexpression. Specifically, HPV16 and 18 accounted together for over 95% of the HPV positive cases. Current HPV vaccines could largely prevent these aggressive tumors. Copyright © 2018 The Authors. Published by Elsevier B.V. All rights reserved.

    Dengue virus infection is an emerging global threat caused by Arbovirus, a virus from Flaviridiae family, which is transmitted by mosquitoes, Aedes aegypti and Aedes albopictus. Renal transplant recipients who live in the endemic zones of dengue infection or who travel to an endemic zone could be at risk of this infection. Despite multiple epidemics and a high case fatality rate in the Southeast Asian region, only a few cases of dengue infection in renal transplant recipients have been reported. Here, we report a case series of 8 dengue viral infection in renal transplant recipients. Of the 8 patients, 3 developed dengue hemorrhagic shock syndrome and died. © 2011 John Wiley & Sons A/S.

    Gastric heterotopia of the intestinal tract can have a diverse clinicopathologic presentation, resulting in a diagnostic dilemma. We present a series of four cases, two male and two female patients with age range of 31-82 years, found in the duodenum, jejunum, and transverse colon. The most common and rather unusual clinical presentation was iron deficiency anemia, seen in three cases, while one patient presented with abdominal pain. Endoscopically, two cases were visualized as pedunculated polyps and two as sessile/plaque-like lesions. Polypectomy was performed in three patients, and one patient underwent biopsy followed by resection. Two cases showed oxyntic-type epithelium, and two cases exhibited pyloric-type gastric epithelium. Three patients were relieved of their presenting symptoms after therapeutic procedures with no evidence of recurrence noted on follow-up. Follow-up was not available on one patient. This case series highlights a diverse clinicopathologic spectrum of gastric heterotopia. Accurate diagnosis is essential for proper management. Copyright © 2018. Published by Elsevier Inc.

    Athletes experiencing hip, groin, and low back pain often exhibit similar clinical characteristics. Individuals with hip, groin and low back pain may have the presence of multiple concurrent pathoanatomical diagnoses. Regardless, similar regional characteristics and dysfunction may contribute to the patient's chief complaint, potentially creating a sub-group of individuals that may be defined by lumbopelvic and hip mobility limitations, motor control impairments, and other shared clinical findings. The purpose of this case series is to describe the conservative management of elite athletes, within the identified aforementioned sub-group, that emphasized regional manual therapy interventions, and therapeutic exercise designed to improve lumbopelvic and hip mobility, stability and motor control. Five elite athletes were clinically diagnosed by a physical therapist with primary pathologies including adductor-related groin pain (ARGP), femoral acetabular impingement (FAI) with acetabular labral lesion and acute, mechanical low back pain (LBP). Similar subjective, objective findings and overall clinical profiles were identified among all subjects. Common findings aside from the chief complaint included, but were not limited to, decreased hip range of motion (ROM), impaired lumbopelvic motor control and strength, lumbar hypomobility in at least one segment, and a positive hip flexion-adduction-internal rotation (FADIR) special test. A three-phase impairment-based physical therapy program was implemented to resolve the primary complaints and return the subjects to their desired level of function. Acute phase rehabilitation consisted of manual therapy and fundamental motor control exercises. Progression to the sub-acute and terminal phases was based on improved subjective pain reports and progress with functional impairments. As the subjects progress through the rehabilitation phases, the delivery of physical therapy interventions were defined by decreased manual therapies

    2016-01-01

    Diabetic Charcot neuroarthropathy is a complex, limb-threatening disease process with major lifestyle-altering repercussions for patients. When Charcot neuroarthropathy leads to unstable deformity, ulceration, and potential infection despite conservative therapies, foot and ankle surgeons often consider reconstructive limb salvage procedures to restore function. The purpose of the present study was to evaluate the clinical and radiographic outcomes of diabetic Charcot reconstruction using combined internal and external fixation. A total of 22 patients were reviewed; 16 (72.73%) midfoot and 6 (27.27%) tibiotalocalcaneal arthrodesis procedures were consecutively performed from March 2009 to May 2013. All surgical procedures were performed in nonacute phases of the Charcot process in patients with diagnosed diabetes mellitus and documented peripheral neuropathy. Patients were excluded from the study if they were not diabetic despite having undergone Charcot reconstruction, regardless of the fixation method, or if they did not complete radiographic imaging. During a mean follow-up period of 58.60 ± 42.37 (range 16 to 164) weeks, limb salvage was achieved in 20 patients (90.91%), and 2 (9.09%) required below-the-knee amputation at a mean of 42 ± 14.14 weeks. Wound dehiscence occurred in 8 (36.36%), pin tract infection in 10 (45.45%), and superficial wound infection in 9 (40.91%) and peaked in bimodal fashion at 4 and 8 weeks postoperatively. Radiographic analysis of the pre- versus postoperative alignment showed statistically significant changes in the lateral talo-first metatarsal angle (p = .02) and lateral talar declination angle (p = .01). The limb salvage rates with diabetic Charcot reconstruction are improving in part because of the continued development of increasingly superior modalities for both internal and external fixation.

    Background: Genital tuberculosis is a chorionic disease and mostly occurs by haematogenous spread from extra genital source like lungs, peritoneum, lymph nodes and bones. Transmission through a sexual intercourse is also possible. Since the majority of patients are in reproductive ages, involvement of fallopian tubes and endometrium cause infertility in patients. Cases: Reviewing 4 cases of female genital tuberculosis, which referred to an infertility treatment center with various symptoms, we encountered various appearances on hysterosalpingography (HSG). Conclusion: The genitourinary tract is the most common site of extra pulmonary TB. The primary focus of genital tuberculosis is fallopian tubes, which are almost always affected bilaterally but not symmetrically. Because of common involvement of fallopian tubes and endometrial cavity, disease causes infertility. Diagnosis is not easy because genital tuberculosis has a wide range of clinical and radiological manifestations with slow growing symptoms. Detailed hysterosalpingography finding may be helpful in better diagnosis of the disease. This case series aims to depict the various hystrosalpingographic appearances and pathology produced by tuberculosis and related literatures are reviewed in order to establish a better diagnostic evaluation of genital tuberculosis.

    North America is home to 2 families of venomous snakes, Crotalinae (pit viper family) and Elapidae (coral snake family). Although there are several published reports describing and reviewing the management of pit viper snakebites in children, there are no recent similar publications detailing the clinical course and management of coral snake envenomation. Our case series describes the hospital course of children with coral snake bites admitted to our regional pediatric intensive care. We also reviewed prior published case reports of coral snake bites in the United States. We identified 4 patients with either confirmed or suspected coral snake envenomation from our hospital's records. In 2 cases, the snakebite occurred after apparent provocation. Antivenom was administered to 3 patients. The regional venom response team was consulted for management advice and supplied the antivenom. One patient had a prolonged hospital course, which was complicated by respiratory failure, bulbar palsy, and ataxia. All survived to discharge. Admission to pediatric intensive care is warranted after all Eastern coral snake bites. A specialized regional or national venom response team can be a useful resource for management advice and as a source of antivenom.

  3. Medical evacuation for unrecognized abdominal wall pain: a case series.

    Chronic abdominal pain is a frequently encountered complaint in the primary care setting. The abdominal wall is the etiology of this pain in 10 to 30% of all cases of chronic abdominal pain. Abdominal cutaneous nerve entrapment at the lateral border of the rectus abdominis muscle has been attributed as a cause of this pain. In the military health care system, patients with unexplained abdominal pain are often transferred to military treatment facilities via the Military Medical Evacuation (MEDEVAC) system. We present two cases of patients who transferred via MEDEVAC to our facility for evaluation and treatment of chronic abdominal pain. Both patients had previously undergone extensive laboratory evaluation, imaging, and invasive procedures, such as esophagogastroduodenoscopy before transfer. Upon arrival, history and physical examinations suggested an abdominal wall source to their pain, and both patients experienced alleviation of their abdominal wall pain with lidocaine and corticosteroid injection. This case series highlights the need for military physicians to be aware of abdominal wall pain. Early diagnosis of abdominal cutaneous nerve entrapment syndrome by eliciting Carnett's sign will limit symptom chronicity, avoid unnecessary testing, and even prevent medical evacuation.

    2012-01-01

    Cemento-ossifying fibroma is a benign fibro-osseous lesion belonging to the same category as fibrous dysplasia and cementifying dysplasia. These are slow-growing lesions that are seen in the third and fourth decades of life. Both the ossifying fibroma and cemento-ossifying fibroma represent two extremes of the same disease process since histologically both contain bone and cementum. However, the term cemento-ossifying fibroma is justified on the basis of clinical and radiological correlation. Radiographs have become an essential tool in the diagnosis of lesions in the jaw, where the anatomy is complex. Nowadays, CT provides information for diagnosis as well as treatment planning. In this case series, we report three cases of cemento-ossifying fibroma that were histologically confirmed and discuss the imaging findings. PMID:23029635

    In a series of nine patients with histopathological diagnosis of hypersensitivity pneumonitis, we retrospectively evaluated clinical data, exposure related factors, pulmonary function tests and chest computed tomography scans. A restrictive abnormality with reduction of diffusion capacity for carbon monoxide was mainly found. Chest scans showed fibrotic patterns in most cases; ground glass attenuation areas with mosaic pattern and consolidation in the rest. Exposure to avian antigens, cereal grains and air conditioners contaminated with fungi yeasts and bacteria, were suspected from clinical data in two-thirds of the cases. Since there are no unique features that allow differentiation from other interstitial lung diseases, a high clinical suspicion is required and a careful search of environmental exposure to possible antigens is needed that, together with clinical, radiological and pathological data, may lead to diagnosis.

    One of the major challenges in the medical domain today is how to exploit the huge amount of data that this field generates. To do this, approaches are required that are capable of discovering knowledge that is useful for decision making in the medical field. Time series are data types that are common in the medical domain and require specialized analysis techniques and tools, especially if the information of interest to specialists is concentrated within particular time series regions, known as events. This research followed the steps specified by the so-called knowledge discovery in databases (KDD) process to discover knowledge from medical time series derived from stabilometric (396 series) and electroencephalographic (200) patient electronic health records (EHR). The view offered in the paper is based on the experience gathered as part of the VIIP project. Knowledge discovery in medical time series has a number of difficulties and implications that are highlighted by illustrating the application of several techniques that cover the entire KDD process through two case studies. This paper illustrates the application of different knowledge discovery techniques for the purposes of classification within the above domains. The accuracy of this application for the two classes considered in each case is 99.86% and 98.11% for epilepsy diagnosis in the electroencephalography (EEG) domain and 99.4% and 99.1% for early-age sports talent classification in the stabilometry domain. The KDD techniques achieve better results than other traditional neural network-based classification techniques.

  7. Headache attributed to airplane travel ('airplane headache'): clinical profile based on a large case series.

    2012-06-01

    The 'headache attributed to airplane travel', also named 'airplane headache' (AH), is a recently described headache disorder that appears exclusively in relation to airplane flights, in particular during the landing phase. Based on the stereotypical nature of the attacks in all reported cases, we proposed provisional diagnostic criteria for AH in a previously published paper. Up to now 37 cases have been described in the literature. After our paper was disseminated via the Internet, we received several email messages from subjects around the world who had experienced such a peculiar headache. Their cooperation, by completing a structured questionnaire and allowing the direct observation of three subjects, enabled us to carry out a study on a total of 75 patients suffering from AH. Our survey confirmed the stereotypical nature of the attacks, in particular with regard to the short duration of the pain (lasting less than 30 minutes in up to 95% of the cases), the clear relationship with the landing phase, the unilateral pain, the male preponderance, and the absence of accompanying signs and/or symptoms. It is conceivable to consider barotrauma as one of the main mechanisms involved in the pathophysiology of AH. The observation that the pain appears inconstantly in the majority of cases, without any evident disorder affecting the paranasal sinuses, could be consistent with a multimodal pathogenesis underlying this condition, possibly resulting in the interaction between anatomic, environmental and temporary concurrent factors. This is by far the largest AH case series ever reported in the literature. The diagnostic criteria that we previously proposed proved to be valid when applied to a large number of patients suffering from this condition. We support its recognition as a new form of headache, to be included in the forthcoming update of the International Headache Society Classification, within '10. Headache attributed to disorder of homoeostasis'. Its formal

    2017-01-01

    Background and Purpose Most rehabilitation interventions after total hip arthroplasty (THA) are not designed to return patients to high-levels of physical activity and, thus, low levels of physical activity and residual weakness are common. The purpose of this case series was to describe the feasibility and preliminary efficacy of an exercise and education intervention for patients after THA who have already completed formal outpatient physical therapy. Study Design Case series Case Description Two participants underwent unilateral THA seven (case A) or eight (case B) months prior to the intervention. Individuals participated in 18 treatment sessions that included progressive aerobic and strengthening exercises and meetings with a health coach. Change in function, strength, and self-reported physical activity were measured. Outcomes 12 months after surgery were compared to a historical cohort of patients after THA. Outcome There were no adverse events during the intervention. At the end of the intervention, hip and knee strength on the surgical side increased approximately 30% compared to baseline in both cases. Activity level, and recreational performance, including walking up stairs and hiking uphill (case A), and running and golfing (case B), improved by the end of the intervention. Most changes were maintained at follow-up, although hip strength for case B decreased 27% after discharge from the intervention. Outcomes for both cases exceeded historical averages for patients 12 months after THA, with the exception of strength in case B. Discussion The exercise intervention was well tolerated and without negative effects in two participants. Both participants increased their ability to complete demanding recreational and sports-related activities, physical activity, and demonstrated improved hip abductor and knee extensor strength. Further research is needed to evaluate the implementation and effectiveness of similar interventions after THA. Level of Evidence

  9. Serious adverse events after HPV vaccination: a critical review of randomized trials and post-marketing case series.

    This article critically reviews HPV vaccine serious adverse events described in pre-licensure randomized trials and in post-marketing case series. HPV vaccine randomized trials were identified in PubMed. Safety data were extracted. Post-marketing case series describing HPV immunization adverse events were reviewed. Most HPV vaccine randomized trials did not use inert placebo in the control group. Two of the largest randomized trials found significantly more severe adverse events in the tested HPV vaccine arm of the study. Compared to 2871 women receiving aluminum placebo, the group of 2881 women injected with the bivalent HPV vaccine had more deaths on follow-up (14 vs. 3, p = 0.012). Compared to 7078 girls injected with the 4-valent HPV vaccine, 7071 girls receiving the 9-valent dose had more serious systemic adverse events (3.3 vs. 2.6%, p = 0.01). For the 9-valent dose, our calculated number needed to seriously harm is 140 (95% CI, 79–653) [DOSAGE ERROR CORRECTED] . The number needed to vaccinate is 1757 (95% CI, 131 to infinity). Practically, none of the serious adverse events occurring in any arm of both studies were judged to be vaccine-related. Pre-clinical trials, post-marketing case series, and the global drug adverse reaction database (VigiBase) describe similar post-HPV immunization symptom clusters. Two of the largest randomized HPV vaccine trials unveiled more severe adverse events in the tested HPV vaccine arm of the study. Nine-valent HPV vaccine has a worrisome number needed to vaccinate/number needed to harm quotient. Pre-clinical trials and post-marketing case series describe similar post-HPV immunization symptoms.

    Tube exposure remains one of the most common complications after glaucoma drainage device (GDD) implantation, despite various types of patch grafts available today. We present a 4 patient case series following the effectivity of the keratolimbal allograft (KLAL) as a patch graft for cases of tube exposure. Given its inherent population of stem cells, our hypothesis was that this highly replicative, biological tissue would provide an adequate means of glaucoma tube coverage. The subset of patients chosen for the KLAL patch graft all had a history of abnormally scarred conjunctiva or thin sclera. The aim of utilizing the KLAL patch with its associated donor conjunctival and scleral ring was also to provide additional reinforcement and adequate tube coverage in the setting of compromised native tissue. Four patients comprised of 2 males and 2 females with a minimum postoperative period of 12 months. All GDDs were initially implanted with a limbal-based incision using either Ahmed glaucoma valve or Baerveldt drainage implant. Three of the 4 patients received the KLAL patch graft after tube exposure with scleral patch graft and 1 patient received KLAL as the primary graft during initial tube placement. Two of the 4 eyes experienced tube re-exposure postoperatively at 2 and 3 months, respectively. Both of these cases had a history of prior tube exposure after scleral patch graft and both were tubes placed in the pars plana. Interestingly, the patients with failed grafts were younger with a history of more ocular surgeries as compared with the patients with graft viable eyes. Through our case series, we found that the KLAL utilized as a patch graft over GDD tubes has the potential for favorable outcomes in certain subtypes of eyes. Although further large scale investigation will be necessary to better define the risk factors associated with graft failure, proving the graft's viability is a crucial first step.

    There are many reports on variations in the inferior vena cava (IVC), particularly double IVC (DIVC) and left IVC (LIVC). However, no systematic report has recorded iliac vein (IV) flow patterns in the DIVC and LIVC. In this study, we examined IV flow patterns in both DIVC and LIVC observed during gross anatomy courses conducted for medical students and in previously reported cases. During the gross anatomy courses, three cases of DIVC and one case of LIVC were found in 618 cadavers. The IV flow pattern from these four cases and all other previously reported cases can be classified into one of the following three types according to the vein into which the internal iliac vein drained: the ipsilateral external IV; confluence of the ipsilateral external IV and IVC; and the communicating vein, which connects the IVC and the contralateral IVC or its iliac branch. This classification, which is based on the internal IV course, is considered to be useful because IV variations have the potential to cause clinical problems during related retroperitoneal surgery, venous interventional radiology, and diagnostic procedures for pelvic cancer.

    To suggest a new surgical approach for posterior opacities or persistent Descemet membrane (DM) detachment in failed deep anterior lamellar keratoplasty (DALK) and to report the outcome of Descemet membrane endothelial keratoplasty (DMEK) in a series of patients with DALK failure. In this retrospective case series of patients who underwent DMEK for failed DALK at Toronto Western Hospital, 4 patients with failed DALK who underwent DMEK surgery were included. In all 4 cases, big bubble formation during initial DALK surgery had failed and the surgical technique was converted to manual dissection using the Melles technique. In 2 cases, the descemetorhexis in DMEK surgery was performed manually, and in 2 cases, the descemetorhexis was performed with the assistance of the femtosecond laser. Four eyes of 4 patients aged 70 ± 4 years were included. Average follow-up time was 9 ± 5 months. Indications for DALK surgery were corneal dystrophy in 2 patients and corneal scars in the other 2. DALK failure was due to persistent DM detachment that created a double chamber in 2 patients and due to posterior lamellar haze in the other 2. After DMEK surgery, 2 patients had graft detachment and required rebubbling. In 1 patient, the DMEK scroll was attached after 1 rebubble attempt, and in the other patient, a second rebubble attempt was needed. The final visual acuities were 20/40, 20/50, 20/70, and 20/200 (because of dense cataract). All procedures were uneventful. DMEK surgery may be effective in managing DALK failure.

    Background/Purpose: Athletes experiencing hip, groin, and low back pain often exhibit similar clinical characteristics. Individuals with hip, groin and low back pain may have the presence of multiple concurrent pathoanatomical diagnoses. Regardless, similar regional characteristics and dysfunction may contribute to the patient's chief complaint, potentially creating a sub-group of individuals that may be defined by lumbopelvic and hip mobility limitations, motor control impairments, and other shared clinical findings. The purpose of this case series is to describe the conservative management of elite athletes, within the identified aforementioned sub-group, that emphasized regional manual therapy interventions, and therapeutic exercise designed to improve lumbopelvic and hip mobility, stability and motor control. Case Descriptions: Five elite athletes were clinically diagnosed by a physical therapist with primary pathologies including adductor-related groin pain (ARGP), femoral acetabular impingement (FAI) with acetabular labral lesion and acute, mechanical low back pain (LBP). Similar subjective, objective findings and overall clinical profiles were identified among all subjects. Common findings aside from the chief complaint included, but were not limited to, decreased hip range of motion (ROM), impaired lumbopelvic motor control and strength, lumbar hypomobility in at least one segment, and a positive hip flexion-adduction-internal rotation (FADIR) special test. A three-phase impairment-based physical therapy program was implemented to resolve the primary complaints and return the subjects to their desired level of function. Acute phase rehabilitation consisted of manual therapy and fundamental motor control exercises. Progression to the sub-acute and terminal phases was based on improved subjective pain reports and progress with functional impairments. As the subjects progress through the rehabilitation phases, the delivery of physical therapy interventions

    Objective. To determine any changes in tuberculosis epidemiology in the last 15 years in Benin, seasonal variations, and forecasted numbers of tuberculosis cases in the next five years. Materials and Methods. Retrospective cohort and time series study of all tuberculosis cases notified between 2000 and 2014. The “R” software version 3.2.1 (Institute for Statistics and Mathematics Vienna Austria) and the Box-Jenkins 1976 modeling approach were used for time series analysis. Results. Of 246943 presumptive cases, 54303 (22%) were diagnosed with tuberculosis. Annual notified case numbers increased, with the highest reported in 2011. New pulmonary bacteriologically confirmed tuberculosis (NPBCT) represented 78%  ± SD 2%. Retreatment cases decreased from 10% to 6% and new pulmonary clinically diagnosed cases increased from 2% to 8%. NPBCT notification rates decreased in males from 2012, in young people aged 15–34 years and in Borgou-Alibori region. There was a seasonal pattern in tuberculosis cases. Over 90% of NPBCT were HIV-tested with a stable HIV prevalence of 13%. The ARIMA best fit model predicted a decrease in tuberculosis cases finding in the next five years. Conclusion. Tuberculosis case notifications are predicted to decrease in the next five years if current passive case finding is used. Additional strategies are needed in the country. PMID:27293887

    Poor cognitive health a major concern of aging individuals, can compromise independent living. More than 16 million people in the United States are affected by cognitive impairment. We have studied the effects of the Feldenkrais Method(®) on cognitive function. In this case series with three participants cognitive function was assessed with the Trail Making Test A and B at baseline and after the Feldenkrais intervention. All participants improved performance on Trail Making Test A and B after completing the Feldenkrais intervention indicating that Feldenkrais lessons may offset age-related decline in cognitive function. The results of this case series warrant larger scale studies on cognitive outcomes of Feldenkrais interventions in clinical and non-clinical populations. Copyright © 2015 Elsevier Ltd.

    2014-09-01

    Background and objectives Metastasis to the breast from extra mammary sites is uncommon with an incidence ranging from 1.2 to 2 % in clinical reports. Approximately 300 cases of breast metastasis from extra mammary sites have been reported, mostly in small series or as a single case report. Gastrointestinal adenocarcinoma metastasising to the breast is also very rare and only 30 cases have been reported in the literature. Metastatic deposits within the breast may be difficult to distinguish from primary breast carcinoma. Radiological features and immunohistochemistry especially for steroid hormone receptors (ER/PR) and expression of gross cystic disease fluid protein (GCDFP) and presence of other immunohistochemistry protein factors in breast metastasis which are specific to primary site may be helpful in differentiating these two conditions. Materials and methods In this series of 3 cases of breast as an unusual site of metastasis, we present different cases of adenocarcinoma of stomach, sigmoid colon and kidney with metastasis to the breast and discuss the differential diagnosis and management plans. Conclusion In conclusion, secondary tumors to the breast are rare and thus differentiating primary tumors from metastatic breast carcinoma is important for rational and optimum therapy and avoidance of unnecessary radical surgery. Palpable breast lump without typical radiological signs of primary breast carcinoma in patients with known primary should be suspected of representing metastasis.

    Internal pancreatic fistulas are a well-known complication of chronic pancreatitis and should be added to the classic complications of malabsorption, diabetes, pain and pseudocyst. The fact that it is an infrequent complication (Bradley compiled about 200 reported cases in 1982) motivated us to make this clinical report. The importance of total parenteral nutrition (NPT), which leads to cure in 50% of these patients, and the usefulness of endoscopic retrograde cholangiopancreatography (ERCP) are evaluated in the cases in which surgery is contemplated.

    Poppers are a recreational substance of abuse belonging to the alkyl nitrite family of compounds. In the United Kingdom, where they are legal to purchase but illegal to sell for human consumption, 10% of the general population have tried them. They are considered low risk to physical and mental health. Two recent case series from France demonstrated foveal pathology in individuals associated with poppers use. A case series of seven patients presenting to four hospitals in the United Kingdom with visual impairment and maculopathy associated with inhalation of poppers. All patients experienced visual symptoms associated with poppers use. The majority had impaired visual acuity, central scotomata, distortion, or phosphenes. Clinical signs on fundoscopy ranged from normal foveal appearance to yellow, dome-shaped lesions at the foveola. Spectral domain optical coherence tomography (SD-OCT) showed varying degrees of disruption of the presumed inner segment/outer segment (IS/OS) junction. Although poppers have been in use for several decades, in 2007, following legislative changes, there was a change in the most commonly used compound from isobutyl nitrite to isopropyl nitrite. There were no reports of 'poppers maculopathy' before this. Poppers maculopathy may be missed if patients are not directly questioned about their use. The disruption or loss of the presumed IS/OS junction on SD-OCT are a characteristic feature. Further study of maculopathy in poppers users is now needed. Raising public awareness of the ocular risks associated with their use may be necessary.

    2012-01-01

    Background In November 2008, a surgical team from the Red Cross Hospital Beverwijk, the Netherlands, was deployed in Afghanistan for three months to attend in the army hospital of Kandahar. During their stay, four incidents of armored personnel carriers encountering an improvised explosive device were assessed. In each incident, two soldiers were involved, whose injuries were strikingly similar. Case presentation The described cases comprise paired thoracic vertebral fractures, radial neck fractures, calcaneal fractures and talar fractures. Moreover, the different types of blast injury are mentioned and related to the injuries described in our series. Acknowledging the different blast mechanisms is important for understanding possible injury patterns. Conclusion From this case series, as well as the existing literature on injury patterns caused by blast injuries, it seems appropriate to pay extra attention to bodily areas that were injured in other occupants of the same vehicle. Obviously, the additional surveillance for specific injuries should be complementary to the regular trauma work-up (e.g., ATLS). PMID:23051981

    A high prevalence of cholestatic disease, including gallbladder mucocele (GBM), has been reported in dogs with naturally occurring pituitary-dependent hyperadrenocorticism (PDH). Differences exist in the clinical features of dogs with PDH and concurrent cholestatic disease, and also is the management of these dogs with trilostane. Sixty-five client-owned dogs with naturally occurring PDH. This was a retrospective, observational case series. Each dog was treated with trilostane for at least 3 months before the study, and had a good clinical response, as determined by owners. Statistical comparisons of clinical signs, results of routine blood tests, basal and post-ACTH cortisol concentration, and optimal trilostane dosage were made after dogs were separated into the following 3 groups by ultrasonographic imaging: normal on ultrasound (NOU) group, cholestasis group, and GBM group. The GBM group had more severe clinical signs and significantly different total serum cholesterol concentration and post-ACTH stimulation cortisol concentration at the time of diagnosis. Dogs that weighed <6 kg had a significantly higher prevalence of cholestatic disease than did the other dogs (P = .003). The optimal trilostane dosages for the GBM and cholestasis groups were 2.5 and 1.5 times the dosage of the NOU group, respectively (P < .001). Gallbladder disease associated with cholestatic disease is correlated with PDH in dogs, in both its clinical features and drug management. These findings may be associated with hypercholesterolemia, unidentified genetic factors, and the hydrophobic nature of trilostane. Copyright © 2017 The Authors.

    The concept of socket preservation by placing a particulate bone allograft or xenograft into a tooth socket or on the alveolar ridge after tooth removal remains a somewhat controversial topic. The concept is that it will preserve the ridge from resorption and such that subsequent implant insertion will be easier, with fewer complications. However, one particular issue is that these materials, although not directly neurotoxic, appear to be an irritant to the nerves if they come in contact with them. We present a case series demonstrating this complication. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.

    Penicillins and cephalosporins are the most widely used antibiotics for the treatment of common infections, and they are the two main classes of β-lactams. On the basis of the time of appearance of the reaction after drug intake and for diagnostic purposes, hypersensitivity reactions to β-lactams have been classified as immediate or non-immediate. The diagnostic evaluation of allergic reactions to β-lactams has changed over the last decade, for several reasons. In many countries, major and minor determinants for skin testing are not available. In immediate allergic reactions, the sensitivity of skin testing is decreasing. For non-immediate reactions, skin testing appears to be less sensitive than previously reported. The drug provocation test is still necessary for diagnosis. In this education review series, we described three cases of β-lactam allergy: first, a child with an IgE-mediated allergy to benzyl-penicillin; second, a child with a non-allergic hypersensitivity to amoxicillin; and in the third patient, we will discuss about cross-reactivity between penicillins and cephalosporins. These cases are correlated with the practical management of evaluating β-lactam allergy. © 2011 John Wiley & Sons A/S.

    Ksharasutra (parasurgical procedure using a thread treated by alkalies) is being practiced in Indian system of medicine since ancient time for management of ano-rectal disorders; particularly for Bhagandara, (fistula in ano), and generally difficult to treat. In this case series, standard Ksharasutra was prepared as per the Ayurvedic Pharmacopeia of India and used to treat the different cases of Bhagandara. In this case series total 6 patients of Bhagandara were treated with Ksharasutra and partial fistulectomy. The average Unit Cutting Time and healing (UCTH) was observed 7.86 days/cm. During treatment Panchawalkala Kwatha (decoction of five medicinal plant's bark), Shatdhautaghrita, Jatyaditaila and Erandabhrishtaharitaki Churna were used as adjuvant drugs. To generate quality evidence Transrectal Ultra Sonography (TRUS) was used in pre as well as post-treatment and showed remarkable tool to assess effect of treatment. Substantial clinical result was observed at the end of treatment and all the patients were free of fistula. No recurrence was observed in any case during the 12 follow up of 12 months. The treatment was reported safe and well tolerated in all the patients. Copyright © 2017 Transdisciplinary University, Bangalore and World Ayurveda Foundation. Published by Elsevier B.V.

    Teratoma is a common form of germ cell tumors composed of multiple tissues foreign to the site in which arise with a histological representation of all three germ cell layers. Intracranial teratomas are very rare. In this study, we report three cases of intracranial teratomas with an interesting clinical course, neuroradiology, and outcome. In addition, we review the literature and convey important messages to the neuroscience community regarding issues related to the management of these rare tumors. The present cases are interesting examples of intracranial teratoma in terms of location of the tumor and neuroimaging findings. Delay in surgical intervention may complicate the course of the disease with progressive enlargement of tumors and development of complication including hydrocephalus. Using endoscopic surgical techniques may emerge as the preferred intervention option as compared to other traditional methods. We recommend the establishment of a national and international registry for intracranial tumors. Copyright © 2017 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

    The etiology of internal root resorption is not fully understandable, trauma and chronic pulpitis are considered the main risk factors. Usually the process is asymptomatic and diagnosed upon routine radiographic examination. This case report presents a rapid progression of internal resorption related directly to traumatic injury. A 16-year-old female arrived at the emergency room after a mild extrusion of the mandibular incisors. The initial treatment included repositioning and splinting of the teeth. Radiographs performed at repositioning and splinting demonstrated normal configuration of the incisor's roots. Ten months later progressive internal resorption of the left mandibular first incisor was diagnosed. While treating this tooth similar process was detected in the right mandibular second incisor and in the mandibular left second incisor. The lower right first incisor reacted inconsistently to vitality test. As a result of the severe and rapidly progressive nature of the process, root canal treatments were performed in all lower incisors. The follow-up radiographs demonstrate arrest of the internal resorption process.

    Young children with neurodevelopmental conditions are often limited in their ability to explore and learn from their environment. The purposes of this case series were to (1) describe the outcomes of using an alternative power mobility device with young children who had multiple, severe impairments; (2) develop power mobility training methods for use with these children; and (3) determine the feasibility of using various outcome measures. Three children with cerebral palsy (Gross Motor Function Classification System Levels IV, V, and V) ages 17 months to 3.5 years participated in the case series. Examination included the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) and the Dimensions of Mastery Questionnaire (DMQ). An individualized, engaging power mobility training environment was created for each participant. Intervention was provided for 60 minutes per week over 12 weeks. All participants exhibited improvements in power mobility skills. Post-intervention PEDI-CAT scores increased in various domains for all participants. Post-intervention DMQ scores improved in Participants 1 and 2. The participants appeared to make improvements in their beginning power mobility skills. Additional research is planned to further explore the impact of power mobility training in this unique population.

    Motor neuron hyperexcitability (MNH) indicates a disorder characterized by an ectopic motor nerve discharge on electromyogram (EMG). Here, we present a series of three cases of subacute MNH with mercury poisoning. The first case showed hyperhidrosis, insomnia, generalied myokymia, cramps, tremor, weight loss, and myokymic and neuromyotonic discharges, followed by encephalopathy with confusion, hallucinations, and memory decrease. The second case was similar to the former but without encephalopathic features. The third case showed widespread fasciculation, fatigue, insomnia, weight loss, and autonomic dysfunction, including constipation, micturition difficulty, and impotence, with multiple fibrillation, unstable fasciculation, widened motor neuron potential, and an incremental response at high-rate stimulation in repetitive nerve stimulation. Based on the symptoms, the three cases were diagnosed as Morvan's syndrome, Isaacs' syndrome, and Lambert-Eaton myasthenic syndrome with ALS-like syndrome, respectively. Mercury poisoning in the three cases was confirmed by analysis of blood and urine samples. All cases recovered several months after chelation therapy and were in good condition at follow-up. Very few cases of MNH linked with mercury exposure have been reported in the literature. The mechanism of mercury-induced MNH may be associated with ion channel dysfunction. © 2014 S.

    Infectious keratitis after PRK remains a rare but potentially devastating complication. Medical records of 3 male patients with infectious keratitis after uneventful PRK for myopia and astigmatism were reviewed retrospectively. PRK was performed using the Wavelight Allegretto excimer laser. Postoperative care included a bandage contact lens (BCL) for 5 days, topical antibiotics, ketorolac, and artificial tears. Keratitis presented 2 - 4 days postoperatively. In one case, each culture was negative (case 1), and was positive for Streptococcus pneumoniae (case 2) and Staphylococcus aureus (case 3). Final BSCVA (best spectacle corrected visual acuity) after intensive antibiotic treatment and removal of BCL were 1.0 (case 1), 0.9 (case 2) and 0.3 correctable to 0.8 with pinhole (case 3). Postoperative broad-spectrum antibiotics are mandatory after PRK to prevent infectious keratitis. However, resistant organisms are more and more common. The presence of a bandage soft contact lens after surgery is an unfavourable element that may increase risk of infection. Based on our case series, we suggest limiting soft contact lens wear during the two postoperative days even if the corneal ulceration is not healed. Copyright Georg Thieme Verlag KG Stuttgart .

    Crimean-Congo hemorrhagic fever (CCHF) is acute viral infection and a major emerging infectious diseases threat, affecting a large geographical area. There is no proven antiviral therapy and it has a case fatality rate of 4-30%. The natural history of disease and outcomes of CCHF in pregnant women is poorly understood. To systematically review the characteristics of CCHF in pregnancy, and report a case series of 8 CCHF cases in pregnant women from Russia, Kazakhstan and Turkey. A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement protocol. PubMed, SCOPUS, Science Citation Index (SCI) were searched for reports published between January 1960 and June 2016. Two independent reviewers selected and reviewed studies and extracted data. Thirty-four cases of CCHF in pregnancy were identified, and combined with the case series data, 42 cases were analyzed. The majority of cases originated in Turkey (14), Iran (10) and Russia (6). There was a maternal mortality of 14/41(34%) and fetal/neonatal mortality of in 24/41 cases (58.5%). Hemorrhage was associated with maternal (p=0.009) and fetal/neonatal death (p<0.0001). There was nosocomial transmission to 38 cases from 6/37 index pregnant cases. Cases of CCHF in pregnancy are rare, but associated with high rates of maternal and fetal mortality, and nosocomial transmission. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    Background and Aim Diagnosis of typhoid is challenging when blood cultures fail to isolate Salmonella species. We report our experience with interpreting computed tomography (CT) abdomen findings in a case series of typhoid fever. Methods The case series consisted of patients who had a CT abdomen done as part of their investigations and a final diagnosis of typhoid fever. The CT films were reviewed and findings evaluated for distinctive features. Results During 2011-2017, 11 patients met the inclusion criteria. Indication for CT was pyrexia of unknown origin in the majority of patients. Review of CT films revealed mesenteric lymphadenopathy (100%), terminal ileum thickening (85%), hepatosplenomegaly (45%), retroperitoneal lymphadenopathy (18%) and ascites (9%). Conclusions Enhancing discrete mesenteric lymphadenopathy and terminal ileum thickening are non-specific findings noted in typhoid fever. Absence of matted necrotic nodes and peritoneal thickening rule out tuberculosis and raise suspicion of typhoid fever in endemic regions.

  13. Bronchiolitis obliterans and consumer exposure to butter-flavored microwave popcorn: a case series.

    2012-01-01

    Respiratory exposure to diacetyl and diacetyl-containing flavorings used in butter-flavored microwave popcorn (BFMP) causes lung disease, including bronchiolitis obliterans (BO), in flavorings and popcorn manufacturing workers. However, there are no published reports of lung disease among BFMP consumers. We present a case series of three BFMP consumers with biopsy-confirmed BO. We review data relating to consumer exposures, estimate case exposures, and compare them to diacetyl-containing flavoring-exposed manufacturing workers with lung disease. These consumer cases' exposure levels are comparable to those that caused disease in workers. We were unable to identify any other exposures or diseases known or suspected to cause BO in these cases. BFMP poses a significant respiratory risk to consumers. Some manufacturers have substituted diacetyl with other alpha-diketones that are likely to pose a similar risk. Simple consumer practices such as cooling the popcorn bag would eliminate the risk of severe lung disease.

    2017-01-01

    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.

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

    The therapeutic effects of written shared case formulations are underexplored and have not been examined in anorexia nervosa. This study explored the relationship between (a) the delivery (b) the quality of a shared written case formulation and weight in outpatient psychological therapy for anorexia nervosa. A naturalistic single case series approach was used to examine the case notes of women who had attended a specialist eating disorders service over a 2-year period. The case notes of 15 adult women who had undergone outpatient psychological therapy for anorexia nervosa with a shared written case formulation component were reviewed. The impact of the quality of the case formulation on weekly weight was examined for 14 of the clients where the case formulation was available. The nature of the relationship between the delivery of the written shared case formulation and weight was examined for all 15 clients. There was some evidence to support an association between delivery of the shared written case formulation and weight changes (both weight gain [five out of 15 clients] and weight loss [three out of 15 clients]) in individual cases. Higher case formulation quality was related to cases where weight change did not occur. The delivery of case formulations can be associated with important therapeutic change (both beneficial and potentially harmful) in anorexia nervosa. Future research into the causal mechanisms associated with sharing formulations will face the challenge of adopting strategies that allow for an in-depth exploration of complex therapy variables whilst overcoming methodological challenges.

    2013-01-01

    The study objective is to evaluate the clinical features and outcomes of patients treated for head and neck malignant fibrous histiocytoma at a tertiary care medical facility. This is a retrospective case series of 17 adult subjects with malignant fibrous histiocytoma of the head and neck who were treated between January 1, 1965, and December 31, 2010. This study was conducted using patient charts at a tertiary medical center. Subject selection was conducted using Current Procedural Terminology numbers; International Classification of Diseases, Ninth Revision, codes; and a search of the tumor registry. Chart review of the 17 identified subjects revealed an overwhelming male predominance (88%) with an overall mean age of 69 years(52-87 years). Thirteen patients (78%) underwent some form of surgical resection, 6 patients (35%) received radiation therapy, and 6 (35%) were given chemotherapy over the course of treatment. Nine tumors (53%) had a cutaneous origin, whereas 8 lesions (47.1%) were found in the soft tissue of the head and neck region. The local recurrence rate following a single resection was 46%. Overall median survival following diagnosis was found to be 65 months, with a 5-year survival rate of 52%. Median disease-free survival was 20 months, with a 5-year disease-free survival rate of 37%. Overall median and 5-year survival rates were found to increase with clear surgical margins, as was 5-year survival. Aggressive surgical management to achieve clear margins is central to the effective treatment of malignant fibrous histiocytoma of the head and neck. Metastatic disease portends a dismal prognosis.

    Aconite poisoning is a severe, life-threatening poisoning related to the use of traditional Chinese medicine (TCM). Despite current legislation, repeated poisoning cases are steadily encountered. The aim of the study was to summarize the clinical features and to elucidate the causative and contributory factors leading to aconite poisoning. This study was conducted within the Hospital Authority Toxicology Reference Laboratory, which is the sole tertiary referral clinical toxicology laboratory in Hong Kong. This retrospective study reviewed all confirmed aconite poisoning cases handled by a clinical toxicology laboratory between April 2004 and July 2009. The diagnosis in all cases was confirmed biochemically by detecting aconitum alkaloids in urine specimens. Additionally, herbal specimens were morphologically identified and herbal formulae were studied and transcribed. The cause of poisoning for each case was determined whenever possible. Fifty-two cases were examined in this aconite poisoning case series. Neurological, cardiovascular and gastrointestinal toxicities were encountered in 49 (94.2%), 46 (88.5%) and 31 (59.6%) patients, respectively. The poisoning was severe in 6 (11.5%) patients, moderate in 17 (32.7%) patients and mild in 29 (55.8%) patients. Amongst 44 patients (84.6%) in whom the underlying reasons of poisoning could be determined, four major causes were found. These included overdose - prescription of a higher than recommended dosage of aconite herbs in 17 (32.7%) cases; 'hidden' poisoning (the aconite herb was not prescribed but dispensed inadvertently) in 17 (32.7%) cases; usage of inadequately processed herbs in 7 (13.5%) cases; and dispensary error in 2 (3.9%) cases. No case fatality was recorded. In the majority of cases in this series, the causes of poisoning can be traced to poor-quality herbs, poor quality of prescription practice, or dispensary errors. The quality issues of TCM practice should be critically addressed to minimize this

    Posterior epidural migrated lumbar disc fragments is an extremely rare disorder. Surgical treatment was performed in all reported cases. To the best of our knowledge, there are no reported cases of the use of conservative treatment for posterior epidural migrated lumbar disc fragments. To report the possibility of a spontaneous regression of posterior epidural migrated lumbar disc fragments. Case series. Four patients with posterior epidural migrated lumbar disc fragments were treated at Karatsu Red Cross Hospital between April 2008 and August 2010. Spontaneous regression of the posterior epidural migrated lumbar disc fragments with relief of symptoms was observed on magnetic resonance imaging (MRI) in three cases. Another patient underwent surgical treatment. The present and previously reported cases of posterior epidural migrated lumbar disc fragments were analyzed with respect to patient age, imaging features on MRI, the level of the lesion, clinical symptoms, treatment, and outcomes. Conservative treatment was successful, and spontaneous lesion regression was seen on MRI with symptom relief in three cases. Although posterior epidural migrated lumbar disc fragment cases are generally treated surgically, the condition can regress spontaneously over time, as do sequestrated disc fragments. Spontaneous regression of lumbar disc herniations is a widely accepted observation at present. Posterior epidural migrated lumbar disc fragments fall under the sequestrated type of disc herniation. In fact, the course of treatment for posterior epidural migrated lumbar disc fragments should be determined based on the symptoms and examination findings, as in cases of ordinary herniation. However, providing early surgical treatment is important if the patient has acute cauda equina syndrome or the neurologic symptoms worsen over time. Copyright © 2015 Elsevier Inc.

    On the basis of a homogeneous series of 412 cases of type IIb primary hyperlipoproteinaemia, the authors compare their experience with findings in the literature. The prevalence of this type of hyperlipoproteinaemia in the general population has been underestimated at 3%. Biological diagnosis remains simple (identification of a double and distinct excess in beta and pre beta lipoproteins). Extravascular lipid deposits (gerontoxon, xanthelasma, tendon xanthomata) are not type specific. Hyperlipidaemic syndrome is rare. Above all, the importance of type IIb in atheromatous disease in the young subject now seems obvious. The mode of hereditary transmission of the familial anomaly is not certain but would appear to be often associated with a double heterozygote condition.

    Cognitive therapy for affective disorders has been recently adapted and developed for the treatment of personality disorders. In the present study, a specific and detailed cognitive therapy treatment manual for borderline and antisocial personality disorders was evaluated in a pilot study. The results of a single case series demonstrate that important clinical changes in dysfunctional behaviour and attitudes can be achieved with short-term cognitive therapy in patients with antisocial and borderline personality disorders, although these were not, on the whole, statistically significant.

    The aim of this 12-year case series was to review the drugs used during anesthetic management of patients with diagnosis of or risk criteria for Brugada syndrome (BrS), and to document any possible association between these drugs and arrhythmogenic activity or unexplained hemodynamic instability. A retrospective clinical observational study. Tertiary hospital. Thirty-one patients met our inclusion criteria: 20 belonging to group D (diagnosed BrS) and 11 to group R (risk of BrS). They underwent a total of 43 anesthetic interventions (28 in group D and 15 in group R). Records from patients with or at risk of BrS who underwent anesthetic intervention at our hospital between May 2003 and May 2015 were retrospectively reviewed. Drugs used were compared with those recommended to be avoided or preferably avoided, published by specialists in the field at brugadadrugs.org. Hemodynamic and cardiac complications during anesthesia were assessed for hypothetical association with these drugs. From the list of drugs available in medical literature recommended to avoid in BrS patients the following were used in our series: propofol (n = 8 in group D, n = 8 in group R), local anesthetics (n = 15 in group D, n = 8 in group R), tramadol (n = 1 in group D), and metoclopramide (n = 1 in group D). Hemodynamic complications occurred in 5 procedures, but no direct association was found between these events and the use of the drugs listed above. Major adverse events related to the deleterious effects of drugs recommended to be avoided were not detected in our series of patients with or at risk of BrS. Although authors cannot refute the theoretical risk of major adverse advents when using known or potential BrS triggers, the true clinical risk of these drugs is unknown, and recommendations to avoid their use should be better supported.

    Marijuana is the most widely abused "recreational" substance in the United States, with highest prevalence in young adults. It is reported to cause ischemic strokes, hepatitis, anxiety, and psychosis. Although it is associated with dose dependent tachycardia and can lead to coronary vasospasm, it has not been directly related to acute myocardial infarction (AMI). Marijuana induced coronary vasospasm can result in endothelial denudation at the site of a vulnerable atherosclerotic plaque in response to hemodynamic stressors, potentially causing an AMI. Spice refers to herbal mixture with composition and effects similar to that of marijuana and therefore is referred to as "synthetic marijuana." Herein, we report 3 cases of spice induced ST-segment elevation myocardial infarction. All patients were relatively young and had few or absolutely no risk factors for cardiovascular disease. All patients underwent emergent coronary angiography, with two needing stent placement and the third requiring only aspiration thrombectomy. Our case series emphasizes the importance of suspecting and investigating synthetic marijuana use in low risk young adults presenting with AMI.

    Demographic and clinical characteristics associated with nonarteritic anterior ischemic optic neuropathy (NAION) are well described. Patients with hematologic neoplasms may share some of these characteristics, and it may be useful clinically to better understand this set of patients. Our objective is to review systematically the characteristics of patients with both hematologic malignancies and NAION. Systematic review. Patients with NAION diagnosis related in time to a hematologic neoplasm. Data sources for the study included MEDLINE, Web of Science, LILACS, SciELO, and OpenGrey. The study eligibility criteria included case reports and case series. We found 261 records, with 15 studies included plus our case report. A total of 19 patients (8 female) with mean age of 54.6 years (range, 12-87) were analyzed: 37% (7) non-Hodgkin lymphoma; 26% (5) myeloproliferative neoplasms; 21% (4) myelodysplasia; 16% (3) leukemias. The limitations included verification bias, inability to test statistical association between NAION and hematologic neoplasms, the small number of cases, and confounding factors related to medical history and specific interventions in each case limited the robustness of our conclusions. Our results identified the characteristics of patients with NAION and hematologic neoplasms related in time. Additional observational studies may enlighten the importance of looking for evidence of an occult neoplastic disorder in patients presenting with NAION. A prompt diagnosis would be of invaluable significance for the best management, in terms of follow-up and therapeutics. Copyright © 2016 Canadian Ophthalmological Society. Published by Elsevier Inc.

    Few studies have compared different methods when exploring the short-term effects of air pollutants on respiratory disease mortality in Wuhan, China. This study assesses the association between air pollutants and respiratory disease mortality with both time-series and time-stratified-case-crossover designs. The generalized additive model (GAM) and the conditional logistic regression model were used to assess the short-term effects of air pollutants on respiratory disease mortality. Stratified analyses were performed by age, sex, and diseases. A 10 μg/m 3 increment in SO 2 level was associated with an increase in relative risk for all respiratory disease mortality of 2.4% and 1.9% in the case-crossover and time-series analyses in single pollutant models, respectively. Strong evidence of an association between NO 2 and daily respiratory disease mortality among men or people older than 65 years was found in the case-crossover study. There was a positive association between air pollutants and respiratory disease mortality in Wuhan, China. Both time-series and case-crossover analyses consistently reveal the association between three air pollutants and respiratory disease mortality. The estimates of association between air pollution and respiratory disease mortality from the case-crossover analysis displayed greater variation than that from the time-series analysis.

    Obstruction of the hepatic hilum in patients without prior surgery is generally due to hilar adenocarcinoma (Klatskin tumor). However, not all the hilar strictures are malignant. Although uncommon, benign strictures of the proximal bile duct should be taken into consideration in differential diagnosis of Klatskin tumors, since the incidence could reach up to 25% of patients with presumed Klatskin tumor diagnosis. This group of benign proximal bile duct strictures (Klatskin-mimicking lesions) is usually represented by segmental fibrosis and non-specific chronic inflammation. The clinical and imaging features can not differentiate between benign and malignant strictures. Herein, we present a case series of three patients with benign proximal bile duct strictures (representing 4.1% of 73 patients resected with presumptive preoperative diagnosis of Klatskin tumor) and literature review. There are presented the clinical and biochemical features, imaging preoperative workup, surgical treatment and histological analysis of the specimen, along with postoperative outcome. For benign strictures of the hilum limited resections are curative. However, despite new diagnosis tools developed in the last years, patients with hilar obstructions still require unnecessary extensive resections due to impossibility of excluding the malignancy. In all cases of proximal bile duct obstruction presumed malignant, they should be managed accordingly, even with the risk of over-treatment for some benign lesions.

    Background Post-intubation tracheoesophageal fistula (PITEF) is an often mistreated, severe condition. This case series reviewed for both the choice and timing of surgical technique and outcome PITEF patients. Methods This case series reviewed ten consecutive patients who had undergone esophageal defect repair and airway resection/reconstruction between 2000 and 2014. All cases were examined for patients: general condition, medical history, preparation to surgery, diagnostic work-up, timing of surgery and procedure, fistula size and site, ventilation type, nutrition, post-operative course and complications. Results All patients were treated according to Grillo’s technique. Overall, 6/10 patients had undergone a preliminary period of medical preparation. Additionally, 3 patients had already had a tracheostomy, one had had a gastrostomy and 4 had both. One patient had a Dumon stent with enlargement of the fistula. Concomitant tracheal stenosis had been found in 7 patients. The mean length of the fistulas was 20.5 mm (median 17.5 mm; range, 8–45 mm), at a median distance from the glottis of 43 mm (range, 20–68 mm). Tracheal resection was performed in all ten cases. The fistula was included in the resection in 6 patients, while it was excluded in the remaining 4 due to their distance. Post-repair tracheotomy was performed in 3 patients. The procedure was performed in 2 ventilated patients. Morbidity related to fistula and anastomosis was recorded in 3 patients (30%), with one postoperative death (10%); T-Tube placement was necessary in 3 patients, with 2/3 decannulations after long-stenting. Definitive PITEF closure was obtained for all patients. At 5-year follow-up, the 9 surviving patients had no fistula-related morbidity. Conclusions Primary esophageal closure with tracheal resection/reconstruction seemed to be effective treatment both short and long-term.

    This paper examines the experiences of nursing students undertaking an international placement during their pre-registration education. The study took place in two schools--one in the United Kingdom, and one in Sweden. The move of nursing education into higher education enabled students to participate in international exchange programmes. Previous research demonstrates that students participating in such programmes may gain enhanced cultural awareness and experience personal and professional growth. The study comprised a multiple case study, utilising semi-structured individual and group interviews and documentary analysis. Eighteen students from the UK and 14 from Sweden participated. Participants described an increase in confidence, self-reliance and professional knowledge and skills resulting from their international placement. There was an awareness of how healthcare roles differ between countries and a change in attitudes to others from different backgrounds and cultures. The differences between the two cases were marginal. Whilst there was support from both home and host universities this varied between the international placement providers. The international placements were beneficial; however, there is a need for change in the preparation, support and monitoring of students, greater engagement with the partner institutions, and more effective mentoring of staff.

    To better characterize the clinical features, electrophysiologic features, and treatment outcomes of painful legs and moving toes (PLMT) syndrome. Large case series. Neurology outpatient clinic at a tertiary referral center, 1983-2011. All cases of PLMT seen at our institution during an 18-year period were identified using our medical record linkage system. Key demographic, clinical, imaging, and electrophysiologic features of PLMT. Treatment outcomes and long-term follow-up are also reported. Of 76 cases identified (including 50 women [66%]), the mean age at onset was 58 years (range, 24-86 years) and at neurologic evaluation was 63 years (range, 26-88 years). Pure lower limb involvement was most common (69 patients [91%]), and 44 cases (58%) were bilateral. The most frequently diagnosed causes were peripheral neuropathy (21 cases [28%]), previous trauma (8 [11%]), and radiculopathy (7 [9%]); 32 cases (42%) were cryptogenic. Electromyography consistently showed irregular 50-millisecond to 1-second bursts of normal motor unit potential firing at 2 to 200 Hz accompanying the movements. Pain occurred first in nearly all cases and was more distressing to patients than the movements. Both components were difficult to treat, with no consistent benefit from a variety of drugs and therapeutic modalities. The syndrome persisted in most patients (83%) during the mean follow-up of 4.6 years, suggesting low likelihood of spontaneous resolution. Painful legs and moving toes syndrome is a debilitating clinical syndrome, not because of the movements but rather because of the pain, which often is refractory to treatment. Segmental lower limb involvement is most common, and neurophysiologic findings support a pathophysiologic process localizing to a central generator at the spinal cord or brainstem level.

  14. EFFECTS OF FOREFOOT RUNNING ON CHRONIC EXERTIONAL COMPARTMENT SYNDROME: A CASE SERIES

    2011-01-01

    Introduction: Chronic exertional compartment syndrome (CECS) is a condition that occurs almost exclusively with running whereby exercise increases intramuscular pressure compromising circulation, prohibiting muscular function, and causing pain in the lower leg. Currently, a lack of evidence exists for the effective conservative management of CECS. Altering running mechanics by adopting forefoot running as opposed to heel striking may assist in the treatment of CECS, specifically with anterior compartment symptoms. Case Description: The purpose of this case series is to describe the outcomes for subjects with CECS through a systematic conservative treatment model focused on forefoot running. Subject one was a 21 y/o female with a 4 year history of CECS and subject two was a 21 y/o male, 7 months status-post two-compartment right leg fasciotomy with a return of symptoms and a new onset of symptoms on the contralateral side. Outcome: Both subjects modified their running technique over a period of six weeks. Kinematic and kinetic analysis revealed increased step rate while step length, impulse, and peak vertical ground reaction forces decreased. In addition, leg intracompartmental pressures decreased from pre-training to post-training. Within 6 weeks of intervention subjects increased their running distance and speed absent of symptoms of CECS. Follow-up questionnaires were completed by the subjects at 7 months following intervention; subject one reported running distances up to 12.87 km pain-free and subject two reported running 6.44 km pain-free consistently 3 times a week. Discussion: This case series describes a potentially beneficial conservative management approach to CECS in the form of forefoot running instruction. Further research in this area is warranted to further explore the benefits of adopting a forefoot running technique for CECS as well as other musculoskeletal overuse complaints. PMID:22163093

    The co-occurrence of pheochromocytoma (PC) and renal tumors was linked to the inherited familial cancer syndrome von Hippel-Lindau (VHL) disease more than six decades ago. Subsequently, other shared genetic causes of predisposition to renal tumors and to PC, paraganglioma (PGL), or head and neck paraganglioma (HNPGL) have been described, but case series of non-VHL-related cases of renal tumor and pheochromocytoma/paraganglioma tumor association syndrome (RAPTAS) are rare. To determine the clinical and molecular features of non-VHL RAPTAS by literature review and characterization of a case series. A review of the literature was performed and a retrospective study of referrals for investigation of genetic causes of RAPTAS. Literature review revealed evidence of an association, in addition to VHL disease, between germline mutations in SDHB, SDHC, SDHD, TMEM127, and MAX genes and RAPTAS [defined here as the co-occurrence of tumors from both classes (PC/PGL/HNPGL and renal tumors) in the same individual or in first-degree relatives]. In both the literature review and our case series of 22 probands with non-VHL RAPTAS, SDHB mutations were the most frequent cause of non-VHL RAPTAS. A genetic cause was identified in 36.3% (8/22) of kindreds. Renal tumors and PC/PGL/HNPGL tumors share common molecular features and their co-occurrence in an individual or family should prompt genetic investigations. We report a case of MAX-associated renal cell carcinoma and confirm the role of TMEM127 mutations with renal cell carcinoma predisposition. Copyright © 2017 Endocrine Society

    2000-07-01

    In the present study, a modification has been proposed of the Blauth and Gekeler classification, aimed at a more accurate definition of appropriate surgical treatment. An analysis was made of a series of 120 cases of symbrachydactyly (117 patients); however, surgery was only performed in 86 cases (51 toe transfers in 49 patients; mean age at surgery 12 months). Type I included the separation of short and sometimes stiff fingers; type II, the 'pseudo-cleft', could be subdivided into three groups. Type IIA included those hands with more than two long and frequently hypoplastic digits, regarding which a decision had to be made between removal of rudimentary fingers or their stabilization. In type IIB, hand function was good and surgery was rarely needed. Type III (monodactylous) could also be subdivided into two categories, i.e., normal thumb in type IIIA and hypoplasia in IIIB. Finally, in type IVA, toe transfer surgery was performed on condition that wrist mobility was sufficient to compensate for the insufficient mobility of the artificial thumb on the anterior aspect of the radius. In all cases, a weak but useful pincer movement was obtained, with poor cosmetic results. In the case of toe transfers, surgery was advocated before the age of one year; and although mobility was disappointing (35 degrees active motion), good growth and excellent discrimination (5 mm on average) was observed. Symbrachydactyly is a fairly frequent congenital malformation; its diverse clinical features require a precise classification to better determine adequate treatment management.

We report on a series of patients with congenital anosmia to analyze its clinical characteristics and present illustrative cases. retrospective chart review. tertiary care centre. thirty-five patients with congenital anosmia were reviewed. A thorough medical history taking, physical examination, and nasal endoscopy were performed in all patients. T&T olfactory testing (n = 33), olfactory event-related potentials (OERPs) (n = 33), and sinonasal computed tomography (CT) (n = 35) were carried out. Magnetic resonance images (MRIs) of the olfactory pathway (n = 34) were available. Serum sex hormones were tested (n = 33). physical examination, olfactory testing, MRI of the olfactory pathway, and serum sex hormones. twenty cases were isolated congenital anosmia (ICA). Fifteen cases were congenital anosmia with other anomalies, including 12 cases with Kallmann syndrome (KS), two with CHARGE syndrome, and one with hypoplasia of the nasal cavity and nasal sinus. T&T olfactory testing indicated anosmia (n = 33). No OERP was obtained (n = 33). CT scans indicated three abnormal patients, including two with unilateral choanal atresia and one with hypoplasia of the nasal cavity and sinus. MRI demonstrated aplasia or hypoplasia of the olfactory bulbs, tracts, and olfactory sulci (n = 34). Serum sex hormones were low in 12 patients with KS. early diagnosis of congenital anosmia on the basis of olfactory symptoms is difficult. MRI of the olfactory pathway plays an important role in anatomic location. ICA is the most common congenital anosmia. KS is the primary presentation of congenital anosmia with other anomalies.

    The cumulative effect of repeated traumatic experiences in early childhood incrementally increases the risk of adjustment problems later in life. Surviving traumatic environments can lead to the development of an interrelated constellation of emotional and interpersonal symptoms termed complex posttraumatic stress disorder (CPTSD). Effective treatment of trauma begins with a multimethod psychological assessment and requires the use of several evidence-based therapeutic processes, including establishing a safe therapeutic environment, reprocessing the trauma, constructing a new narrative, and managing emotional dysregulation. Therapeutic Assessment (TA) is a semistructured, brief intervention that uses psychological testing to promote positive change. The case study of Kelly, a middle-aged woman with a history of repeated interpersonal trauma, illustrates delivery of the TA model for CPTSD. Results of this single-case time-series experiment indicate statistically significant symptom improvement as a result of participating in TA. We discuss the implications of these findings for assessing and treating trauma-related concerns, such as CPTSD.

    Gastrointestinal (GI) motility disorders are common in children. Treatment is challenging with limited medical and surgical options. Pyridostigmine, an acetyl cholinesterase inhibitor, increases acetylcholine at the neuromuscular junction promoting intestinal contractions. Little is known about the role and dosing of pyridostigmine in pediatric GI motility disorders. We present a case series of children with GI dysmotility managed with oral pyridostigmine. Patients' diagnoses include chronic intestinal pseudo-obstruction, gastroparesis with delayed small bowel transit, chronic constipation with failure to thrive, and prolonged ileus after pelvic surgery with chronic opioid use. Pyridostigmine was effective and safe in all cases. Pyridostigmine decreased abdominal distention, increased bowel movement frequency, and improved enteral feeding tolerance. Effective dosing ranged between 0.25-2.0 mg/kg/day. One patient experienced cramping abdominal pain while on pyridostigmine, but pain resolved after medication was discontinued. We found oral pyridostigmine to be helpful in children with different GI motility problems. Pyridostigmine should be considered in such patients when other treatment interventions have not been beneficial.

    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.

    Chronic hypopituitarism following Russell viper envenomation (RVE) is a rare but well-recognized syndrome. The clinical features, associations, management and outcomes of RVE associated-acute hypopituitarism (AHP) are not well described. To describe the clinical features, intensive care unit (ICU) management and outcomes of a series of patients with RVE-AHP and identify the clinical associations of RVE-AHP. We describe a series of patients with prospectively identified AHP related to RVE and describe our findings comparing RVE with and without AHP and a systematic search of literature on AHP related to RVE. We identified nine cases of AHP related to RVE. Unexplained hypoglycemia (100%) and hypotension (66.7%) were the most common findings at presentation. AHP occurred after a median of 9 (range, 2-14) days after severe envenomation and was associated with multi-organ dysfunction, lower platelet counts, more bleeding and transfusions when compared to patients with RVE alone. The presence of clinically defined capillary leak syndrome, disseminated intravascular coagulation and mortality were not different from those without AHP. Our systematic search yielded 12 cases of AHP related to RVE; data on associated clinical manifestations, therapy and ASV administration were not available in most reports. AHP is a very rare complication of RVE. Unexplained hypoglycemia and hypotension should prompt evaluation for AHP in RVE. AHP is associated with severe RVE, multi-organ dysfunction, bleeding and need for transfusion. Prompt treatment with steroids may reduce mortality related to AHP in RVE. © The Author 2015.

    Objective: The research provides an understanding of pandemic information needs and informs professional development initiatives for librarians in disaster medicine. Methods: Utilizing a multisite, comparative case series design, the researchers conducted semi-structured interviews and examined supplementary materials in the form of organizational documents, correspondence, and websites to create a complete picture of each case. The rigor of the case series was ensured through data and investigator triangulation. Interview transcripts were coded using NVivo to identify common themes and points of comparison. Results: Comparison of the four cases revealed a distinct difference between “client-initiated” and “librarian-initiated” provision of pandemic information. Librarian-initiated projects utilized social software to “push” information, whereas client-initiated projects operated within patron-determined parameters to deliver information. Health care administrators were identified as a key audience for pandemic information, and news agencies were utilized as essential information sources. Librarians' skills at evaluating available information proved crucial for selecting best-quality evidence to support administrative decision making. Conclusions: Qualitative analysis resulted in increased understanding of pandemic information needs and identified best practices for disseminating information during periods of high organizational stress caused by an influx of new cases of an unknown infectious disease.

    Cognitive remediation therapy (CRT) is a treatment targeting cognitive difficulties in psychiatric disorders. CRT has been used with patients with severe anorexia nervosa (AN) in individual and group formats. Research of group CRT in AN is limited. Evaluation of a series of CRT groups delivered in inpatient and intensive daycare services was performed. Participants' self-reported cognitive flexibility and central coherence, as well as motivation to change were assessed pre- and post-group. Additionally, patients' evaluative feedback was collected after completion of the group. There was a significant improvement in the patients' self-reported cognitive flexibility and bigger picture thinking, as well as in their self-efficacy to change. The feedback questionnaires highlighted that patients found the sessions useful and reported confidence in using some of the skills and strategies they learnt in the group. In line with evidence from small-scale reports, this larger scale case series study indicates that group CRT leads to increased flexibility and bigger picture thinking, as well as improved confidence in the ability to change for participants. CRT in a group format seems to be a practical and helpful intervention for patients with AN in intensive treatment programmes.

    Piezoelectric surgery is a novel surgical approach used in orthodontic treatment for rapid tooth movement. This paper presents a case series wherein osseous outgrowths were observed in response to piezosurgery-assisted en-masse retraction. Sixteen patients requiring upper premolar extractions were treated with miniscrew-supported en-masse retraction and received minimally invasive decortication via piezosurgery. Computed tomography (CT) of the maxillary anterior region was performed to investigate the nature of the outgrowths. In 8 of the 16 patients, hemispheric or disc-shaped osseous outgrowths were observed on the sites where piezosurgery was performed during retraction. CT images revealed that these outgrowths were alveolar bone. This case series presents a previously unreported osseous response to piezosurgery-assisted tooth movement during orthodontic treatment. The response is mostly transient and is observed in 50% of the treated patients, suggesting a bone turnover that can be assessed clinically and radiographically.

    Cases of rare-earth magnet ingestions have been increasingly reported in the literature. However, these descriptions have focused on the severity of the injuries, rather than the clinical presentation and/or therapeutic approach. We report a series of eight children, ranging in age from 2 to 10 years, who ingested powerful rare-earth magnets. The rare-earth magnets were marketed in 2009 under the trade name Buckyballs(®) (Maxfield & Oberton, New York, NY). They are about 5 mm in size, spherical, and brightly colored, making them appealing for young children to play with and place in their mouths. Three children presented within hours of ingestion, and the magnets were successfully removed via endoscopy in two, whereas the third child required laparoscopy. No fistulas were found in these children. A fourth child presented 2 days after ingestion with evidence of bowel wall erosion, but without fistula formation; the magnets were removed via laparoscopy. A fifth child ingested nine magnets in a ring formation, which were removed via colonoscopy without evidence of injury or fistula formation. The three remaining children presented late (5-8 days after ingestion) and were found to have associated fistulas. They were treated successfully with a combination of endoscopy and laparoscopy with fluoroscopy. None of the children in our series required an open surgical procedure. All children were discharged home without complications. This case series highlights the potential dangers of rare-earth magnet ingestion in children. Our experience suggests that prompt intervention using minimally invasive approaches can lead to successful outcomes.

    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.

    Intraosseous vascular access is a time-tested procedure that is reemerging in popularity. This is primarily a result of the emphasis on intraosseous access in the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Advanced Cardiac Life Support. Modern intraosseous insertion devices are easy to learn and use, suggesting the possibility of use beyond the resuscitation setting. We present a case series of recent intraosseous insertions for a variety of indications by anesthesiologists at our institution to demonstrate the potential utility of this alternative access technique.

    The field of periodontal plastic surgery is always a subject of fascination for periodontists, and the importance of pink esthetics is gaining its pace. Preservation of what is existing is more important than its replacement. The same principle also applies to soft-tissue esthetic procedures thereby the concept of minimal surgical invasion came into existence. This article presents a series of five cases with 18 recession sites which were treated with a minimally invasive Pinhole Surgical Technique which resulted in overall root coverage of 96.7% after 6-month follow-up with minimal complications.

    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.

  16. Serous endometrial intraepithelial carcinoma: a case series and literature review.

    2013-01-01

    Minimal uterine serous cancer (MUSC) or serous endometrial intraepithelial carcinoma (EIC) has been described by many different names since 1998. There have been very few cases reported in literature since EIC/MUSC was recognized as a separate entity. The World health Organization (WHO) Classification favors the term serous EIC. Although serous EIC is confined to the uterine endometrium at initial histology diagnosis, a significant number of patients could have distal metastasis at diagnosis, without symptoms. Serous EIC is considered as being the precursor of uterine serous cancer (USC), but pure serous EIC also has an aggressive behavior similar to USC. It is therefore prudent to have an accurate diagnosis and appropriate surgical staging. There are very few published articles in literature that discuss the pure form of serous EIC. The aim of this series is to share our experience and review evidence for optimum management of serous EIC. We report a series of five women treated in our institute in the last 3 years. We reviewed the relevant literature on serous EIC and various management strategies, to recommend best clinical practice. Pure serous EIC is a difficult histopathological diagnosis, which requires ancillary immunohistochemical staining. It can have an aggressive clinical behavior with early recurrence and poor survival. Optimum surgical staging, with appropriate adjuvant treatment, should be discussed when treating these patients.

  17. The international performance of healthcare systems in population health: capabilities of pooled cross-sectional time series methods.

    This paper outlines the capabilities of pooled cross-sectional time series methodology for the international comparison of health system performance in population health. It shows how common model specifications can be improved so that they not only better address the specific nature of time series data on population health but are also more closely aligned with our theoretical expectations of the effect of healthcare systems. Three methodological innovations for this field of applied research are discussed: (1) how dynamic models help us understand the timing of effects, (2) how parameter heterogeneity can be used to compare performance across countries, and (3) how multiple imputation can be used to deal with incomplete data. We illustrate these methodological strategies with an analysis of infant mortality rates in 21 OECD countries between 1960 and 2008 using OECD Health Data. Copyright © 2013 The Author.

    Paget-Schroetter syndrome (PSS) in the context of upper extremity deep venous thrombosis (DVT) is an uncommon but potentially very serious condition affecting young, healthy adults, in which secondary post-thrombotic syndrome (PTS) can be a complication with major implications. The best treatment option remains controversial, with current guidelines recommending anticoagulation for at least 3 months. However, an incidence of PTS of approximately 50% after 6 months, 30% after 1 year and 25% after 2 years has been found using this therapeutic approach. Consequently, specialized units recommend local thrombolysis and early decompressive surgery. We describe a series of eight cases treated in this way. None of the patients showed signs of complications, and an early return to regular activities with no PTS was observed in 90% of cases. Copyright © 2014 SEPAR. Published by Elsevier Espana.

    Sport-related concussion is a topic of increasing public and media attention; the medical literature on this topic is growing rapidly. However, to our knowledge no published papers have described concussion specifically in the dancer. This case series involved a retrospective chart review at a large teaching hospital over a 5.5-year period. Eleven dancers (10 female, 1 male) were identified who experienced concussions while in dance class, rehearsal, or performance: 2 in classical ballet, 2 in modern dance, 2 in acro dance, 1 in hip hop, 1 in musical theater, and 3 were unspecified. Dancers were between 12 and 20 years old at the time of presentation. Three concussions occurred during stunting, diving, or flipping. Three resulted from unintentional drops while partnering. Two followed slips and falls. Two were due to direct blows to the head, and one dancer developed symptoms after repeatedly whipping her head and neck in a choreographed movement. Time to presentation in the sports medicine clinic ranged from the day of injury to 3 months. Duration of symptoms ranged from less than 3 weeks to greater than 2 years at last documented follow-up appointment. It is concluded that dancers do suffer dance-related concussions that can result in severe symptoms, limitations in dance participation, and difficulty with activities of daily living. Future studies are needed to evaluate dancers' recognition of concussion symptoms and care-seeking behaviors. Additional work is also necessary to tailor existing guidelines for gradual, progressive, safe return to dance.

    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.

    Acute and chronic wounds afflict a multitude of patients to varying degrees. Wound care treatment modalities span the spectrum of technological advancement and with that differ greatly in cost. Negative pressure wound therapy (NPWT) can now be combined with instillation and dwell time (NPWTi-d). This case review series of 11 patients in a community hospital setting provides support for the utilization of NPWTi-d. Additionally, current literature on the use of NPWTi-d in comparison to NPWT will be reviewed.  We highlight three specific cases. The first case is a 16-year-old male who was shot in the left leg. He suffered a pseudoaneurysm and resultant compartment syndrome. This required a fasciotomy and delayed primary closure. To facilitate this, NPWTi-d was employed and resulted in a total of four operative procedures before closure 13 days after admission. Next, a 61-year-old uncontrolled diabetic female presented with necrotizing fasciitis of the lower abdomen and pelvis. She underwent extensive debridement and placement of NPWTi-d with Dakin's solution. A total of four operative procedures were performed including delayed primary closure six days after admission. Finally, a 48-year-old female suffered a crush injury with internal degloving. NPWTi-d with saline was utilized until discharge home on postoperative day 12. NPWTi-d, when compared to NPWT, has been reported to lead to a decrease in time to operative closure, hospital length of stay, as well as operative procedures required. The cost-benefit analysis in one retrospective review noted a $1,400 savings when these factors were taken into account. This mode of wound care therapy has significant benefits that warrant the development of a prospective randomized controlled trial to further define the improvement in quality-of-life provided to the patient and the reduction of potential overall healthcare costs.

  3. Increased internal higher-order aberrations as a useful parameter for indication of vitrectomy in three asteroid hyalosis cases

    We report three asteroid hyalosis cases in which internal higher-order aberrations (HOAs) were improved concomitant with improved visual symptoms after vitrectomy. Cases 1 and 2 reported severe floaters and glare disability, although their visual acuities were fairly good. Case 3 showed poor visual acuity since this patient also suffered from mild macular degeneration. For these three asteroid hyalosis cases, we were unsure if treatment with vitrectomy could improve visual symptoms. Therefore, we measured internal HOAs with an aberrometer, and found that the internal HOA values in these cases were high. We suspected that internal high HOAs values were associated with visual disturbance, and performed vitrectomy. After the vitrectomy, the internal HOA values in these three asteroid hyalosis cases markedly decreased, and visual symptoms improved. These observations suggested that measurement of internal HOAs may be useful to determine the indication for vitrectomy. PMID:26698200

    IMPORTANCE Cutaneous Rosai-Dorfman disease (CRDD), a variant of Rosai-Dorfman disease limited to the skin, has a wide range of clinical presentations. Rosai-Dorfman disease is believed to result from an aberrant response to antigens, caused by immunosuppressive macrophages. Macrophage-mediated immunosuppression is also implicated in the pathogenesis of Crohn disease, linking these otherwise unrelated entities. To our knowledge, the coexistence of these disorders has been described in only 2 cases, 1 of them confined to the skin and soft tissue. OBSERVATIONS We present a series of 3 patients who developed purely CRDD in the context of long-standing Crohn disease. Statistical estimates suggested that the association of these 2 disorders is not due to chance (P<.001). CONCLUSIONS AND RELEVANCE Our case series provides the clinical correlate to the pathogenetic parallels between CRDD and Crohn disease. Crohn disease is frequently complicated by various skin manifestations, which may be mimicked by CRDD. Therefore, it may be prudent for clinicians to include CRDD in the list of differential diagnoses when examining skin lesions in patients with Crohn disease.

    Treatment innovation for bipolar disorder has been hampered by a lack of techniques to capture a hallmark symptom: ongoing mood instability. Mood swings persist during remission from acute mood episodes and impair daily functioning. The last significant treatment advance remains Lithium (in the 1970s), which aids only the minority of patients. There is no accepted way to establish proof of concept for a new mood-stabilizing treatment. We suggest that combining insights from mood measurement with applied mathematics may provide a step change: repeated daily mood measurement (depression) over a short time frame (1 month) can create individual bipolar mood instability profiles. A time-series approach allows comparison of mood instability pre- and post-treatment. We test a new imagery-focused cognitive therapy treatment approach (MAPP; Mood Action Psychology Programme) targeting a driver of mood instability, and apply these measurement methods in a non-concurrent multiple baseline design case series of 14 patients with bipolar disorder. Weekly mood monitoring and treatment target data improved for the whole sample combined. Time-series analyses of daily mood data, sampled remotely (mobile phone/Internet) for 28 days pre- and post-treatment, demonstrated improvements in individuals' mood stability for 11 of 14 patients. Thus the findings offer preliminary support for a new imagery-focused treatment approach. They also indicate a step in treatment innovation without the requirement for trials in illness episodes or relapse prevention. Importantly, daily measurement offers a description of mood instability at the individual patient level in a clinically meaningful time frame. This costly, chronic and disabling mental illness demands innovation in both treatment approaches (whether pharmacological or psychological) and measurement tool: this work indicates that daily measurements can be used to detect improvement in individual mood stability for treatment innovation (MAPP).

    2017-03-27

    Septic shock, defined as life-threatening organ dysfunction caused by a dysregulated host response to infection, is a highly lethal condition that causes substantial morbidity and mortality among critically ill patients. One of the hallmarks of sepsis is the excessive release of cytokines and other inflammatory mediators causing refractory hypotension, tissue damage, metabolic acidosis and ultimately multiple organ failure. In this context, cytokine reduction by hemoadsorption represents a new concept for blood purification, developed to attenuate the overwhelming systemic levels of pro-inflammatory and anti-inflammatory mediators released in the early phase of sepsis. In the present case series, we evaluated the impact of a new hemoadsorption device (CytoSorb) used as adjunctive therapy, on hemodynamics and clinically relevant outcome parameters in 26 critically ill patients with septic shock and in need of renal replacement therapy. We found that treatment of these patients with septic shock was associated with hemodynamic stabilization and a reduction in blood lactate levels. Actual mortality in the overall patient population was lower than mortality predicted by acute physiology and chronic health evaluation II (APACHE II). These effects seem to be more pronounced in patients in whom therapy started within 24 h of sepsis diagnosis, whereas a delay in the start of therapy was associated with a poor response to therapy in terms of reduction of catecholamine demand and survival. Moreover, from our patient population, medical patients seemed to benefit more than post-surgical patients in terms of survival. Treatment using the CytoSorb device was safe and well-tolerated with no device-related adverse events during or after the treatment sessions. Hemoadsorption using CytoSorb resulted in rapid hemodynamic stabilization and increased survival, particularly in patients in whom therapy was started early.

    Intrathoracic pressure regulation (IPR) is a novel, noninvasive therapy intended to increase cardiac output and blood pressure in hypotensive states by generating a negative end expiratory pressure of -12 cm H2O between positive pressure ventilations. In this first feasibility case-series, we tested the hypothesis that IPR improves End tidal (ET) CO2 during cardiopulmonary resuscitation (CPR). ETCO2 was used as a surrogate measure for circulation. All patients were treated initially with manual CPR and an impedance threshold device (ITD). When IPR-trained medics arrived on scene the ITD was removed and an IPR device (CirQLATOR™) was attached to the patient's advanced airway (intervention group). The IPR device lowered airway pressures to -9 mmHg after each positive pressure ventilation for the duration of the expiratory phase. ETCO2, was measured using a capnometer incorporated into the defibrillator system (LifePak™). Values are expressed as mean ± SEM. Results were compared using paired and unpaired Student's t test. p values of <0.05 were considered statistically significant. ETCO2 values in 11 patients in the case series were compared pre and during IPR therapy and also compared to 74 patients in the control group not treated with the new IPR device. ETCO2 values increased from an average of 21 ± 1 mmHg immediately before IPR application to an average value of 32 ± 5 mmHg and to a maximum value of 45 ± 5mmHg during IPR treatment (p<0.001). In the control group ETCO2 values did not change significantly. Return of spontaneous circulation (ROSC) rates were 46% (34/74) with standard CPR and ITD versus 73% (8/11) with standard CPR and the IPR device (p<0.001). ETCO2 levels and ROSC rates were significantly higher in the study intervention group. These findings demonstrate that during CPR circulation may be significantly augmented by generation of a negative end expiratory pressure between each breath. Copyright © 2012 Elsevier Ireland Ltd.

    To assess the efficacy and safety of porous and nonporous implants for management of the anophthalmic socket. Case series meta-analysis was conducted with no language restriction, including studies from: PUBMED, EMBASE and LILACS. Study eligibility criteria were case series design with more than 20 cases reported, use of porous and/or nonporous orbital implants, anophthalmic socket and, treatment success defined as no implant exposure or extrusion. Complications rates from each included study were quantified. Proportional meta-analysis was performed on both outcomes with a random-effects model and the 95% confidential intervals were calculated. A total of 35 case series studies with a total of 3,805 patients were included in the meta-analysis. There are no studies comparing porous and nonporous implants in the anophthalmic socket treatment. There was no statistically significant difference between porous polyethylene (PP) and hydroxyapatite (HA) on implant exposure: 0.026 (0.012-0.045) vs 0.054 (0.041-0.070), respectively and, neither on implant extrusion: 0.0042 (0.0008-0.010) vs. 0.018 (0.004-0.042), respectively. However, there was a significant difference supporting the use of PP when compared to bioceramic implant: 0.026 (0.012 -0.045) vs. 0.12 (0.06-0.20), respectively, on implant exposure. PP implants showed lower chance of exposure than bioceramic implant for anophthalmic socket reconstruction, although we cannot rule out the possibility of heterogeneity bias due to the nature and level of evidence of the included studies. Clinical trials are necessary to expand the knowledge of porous and nonporous orbital implants in the anophthalmic socket management.

    A xenogeneic collagen matrix recently has been suggested as an alternative to connective tissue graft for the treatment of gingival recession. The matrix avoids the second surgical site, and as a consequence could decrease surgical morbidity. This new matrix was used in various clinical situations and compared to connective tissue graft (CTG) in a split-mouth design case series. A total of 17 recessions were treated with a coronally advanced flap, 9 with CTG, and 8 with the matrix. Mean recession reduction was 2.00 mm with the CTG and 2.00 mm with the matrix. No significant statistical differences between the techniques were observed in this case report.

    Few studies have compared different methods when exploring the short-term effects of air pollutants on respiratory disease mortality in Wuhan, China. This study assesses the association between air pollutants and respiratory disease mortality with both time-series and time-stratified–case-crossover designs. The generalized additive model (GAM) and the conditional logistic regression model were used to assess the short-term effects of air pollutants on respiratory disease mortality. Stratified analyses were performed by age, sex, and diseases. A 10 μg/m3 increment in SO2 level was associated with an increase in relative risk for all respiratory disease mortality of 2.4% and 1.9% in the case-crossover and time-series analyses in single pollutant models, respectively. Strong evidence of an association between NO2 and daily respiratory disease mortality among men or people older than 65 years was found in the case-crossover study. There was a positive association between air pollutants and respiratory disease mortality in Wuhan, China. Both time-series and case-crossover analyses consistently reveal the association between three air pollutants and respiratory disease mortality. The estimates of association between air pollution and respiratory disease mortality from the case–crossover analysis displayed greater variation than that from the time-series analysis.

    Pediatric patients account for 35% of all cases that present after ocular trauma and 20.9% of those result in a ruptured globe. When repairing the globe, the removal of the natural lens results in a significant change in refractive error and loss of accommodation. In addition, the eye can have scarring, irregular astigmatism, and changes to the ocular surface. Treatment and vision rehabilitation should be aggressive and done quickly to prevent amblyopia. Advanced lens designs are often needed to treat both the irregular ocular surface and the aphakia. Treatment options are often confounded with the usual issues of contact lens compliance, intolerance, and complications. This case series follows three aphakic pediatric patients through the contact lens fitting process after sustaining a ruptured globe that left them aphakic with residual irregular astigmatism and corneal scarring. Patient 1 is a 3-year-old Hispanic male fit with a bitoric gas permeable contact lens with irregular astigmatism and an elevated central corneal scarring. Patient 2 is a 12-year-old Caucasian male with minimal residual astigmatism fit in a multifocal soft contact lens. Patient 3 is an 8-year-old African American male fit with a hybrid contact lens that was needed to vault the irregular astigmatism and central corneal scarring. Treating patients with irregular corneas or aphakia can be challenging in their own right, but in combination are some of the most advanced specialty contact lens fittings. This case series followed three pediatric patients through the fitting process and demonstrated the options and challenges when fitting this unique patient population.

    Retinopathy of prematurity (ROP) is an eye disease caused by an alteration in retinal vasculogenesis that may lead to partial or complete vision loss with a harmful impact in terms of neurodevelopment. The purpose of the present study was to determine the neurodevelopment in patients with type i retinopathy of prematurity treated with intravitreal bevacizumab. Case series. The inclusion criteria were: patients with type I ROP treated with a dose of 0.625mg/0.025ml of intravitreal bevacizumab. Demographic data and comorbidities were documented. Neurodevelopment was evaluated with the screening test of the Bayley Scale of Infant Development (BSID) in all patients between 11 and 28 weeks of age. Seven patients were included in the study. Four patients showed normal neurodevelopment according to the overall scores of the BSID scale. The distribution of high risk for neurodevelopmental delay in the different areas evaluated were as follows: 3 patients presented it in the cognitive area, one in the receptive communication area, one in the expressive area, one in the fine motor skills and 3 patients in the gross motor skills area. In these case series, the majority of patients treated with intravitreal bevacizumab for ROP showed normal neurodevelopment scores. Copyright © 2016 Academia Mexicana de Cirugía A.C.

    OBJECTIVE The goal of this study was to provide insight into the influence of gliomas on gestational outcomes, the impact of pregnancy on gliomas, and the identification of patients at risk. METHODS In this multiinstitutional retrospective study, the authors identified 52 pregnancies in 50 women diagnosed with a glioma. RESULTS For gliomas known prior to pregnancy (n = 24), we found the following: 1) An increase in the quantified imaging growth rates occurred during pregnancy in 87% of cases. 2) Clinical deterioration occurred in 38% of cases, with seizures alone resolving after delivery in 57.2% of cases. 3) Oncological treatments were immediately performed after delivery in 25% of cases. For gliomas diagnosed during pregnancy (n = 28), we demonstrated the following: 1) The tumor was discovered during the second and third trimesters in 29% and 54% of cases, respectively, with seizures being the presenting symptom in 68% of cases. 2) The quantified imaging growth rates did not significantly decrease after delivery and before oncological treatment. 3) Clinical deterioration resolved after delivery in 21.4% of cases. 4) Oncological treatments were immediately performed after delivery in 70% of cases. Gliomas with a high grade of malignancy, negative immunoexpression of alpha-internexin, or positive immunoexpression for p53 were more likely to be associated with tumor progression during pregnancy. Deliveries were all uneventful (cesarean section in 54.5% of cases and vaginal delivery in 45.5%), and the infants were developmentally normal. CONCLUSIONS When a woman harboring a glioma envisions a pregnancy, or when a glioma is discovered in a pregnant patient, the authors suggest informing her and her partner that pregnancy may impact the evolution of the glioma clinically and radiologically. They strongly advise a multidisciplinary approach to management. ■ CLASSIFICATION OF EVIDENCE Type of question: association; study design: case series; evidence: Class IV.

    The Therapeutic Assessment (TA) model is a relatively new treatment approach that fuses assessment and psychotherapy. The study examines the efficacy of this model with preadolescent boys with oppositional defiant disorder and their families. A replicated single-case time-series design with daily measures is used to assess the effects of TA and to track the process of change as it unfolds. All 3 families benefitted from participation in TA across multiple domains of functioning, but the way in which change unfolded was unique for each family. These findings are substantiated by the Behavior Assessment System for Children (Reynolds & Kamphaus, 2004). The TA model is shown to be an effective treatment for preadolescent boys with oppositional defiant disorder and their families. Further, the time-series design of this study illustrated how this empirically grounded case-based methodology reveals when and how change unfolds during treatment in a way that is usually not possible with other research designs.

    To illustrate ways in which clinical decision support systems (CDSSs) malfunction and identify patterns of such malfunctions. We identified and investigated several CDSS malfunctions at Brigham and Women's Hospital and present them as a case series. We also conducted a preliminary survey of Chief Medical Information Officers to assess the frequency of such malfunctions. We identified four CDSS malfunctions at Brigham and Women's Hospital: (1) an alert for monitoring thyroid function in patients receiving amiodarone stopped working when an internal identifier for amiodarone was changed in another system; (2) an alert for lead screening for children stopped working when the rule was inadvertently edited; (3) a software upgrade of the electronic health record software caused numerous spurious alerts to fire; and (4) a malfunction in an external drug classification system caused an alert to inappropriately suggest antiplatelet drugs, such as aspirin, for patients already taking one. We found that 93% of the Chief Medical Information Officers who responded to our survey had experienced at least one CDSS malfunction, and two-thirds experienced malfunctions at least annually. CDSS malfunctions are widespread and often persist for long periods. The failure of alerts to fire is particularly difficult to detect. A range of causes, including changes in codes and fields, software upgrades, inadvertent disabling or editing of rules, and malfunctions of external systems commonly contribute to CDSS malfunctions, and current approaches for preventing and detecting such malfunctions are inadequate. CDSS malfunctions occur commonly and often go undetected. Better methods are needed to prevent and detect these malfunctions. © The Author 2016.

    BACKGROUND Liver abscesses represent a serious infection of hepatic parenchyma and are associated with significant morbidity and mortality. The emergence of a new hypervirulent variant of Klebsiella pneumoniae, which can cause serious infections in the Asian population, is under investigation. We report a case series of six Asian patients hospitalized at our institution from January 2013 to November 2015 for liver abscess due to Klebsiella pneumoniae. CASE REPORT Charts of six Asian patients were retrospectively reviewed. Four patients were male and two were female. The mean age was 53 years (range: 35-64 years). All patients had no known past medical history of immunodeficiency. Three patients had multiple liver abscesses at the time of initial presentation. In five patients, the source of entry of the pathogenic microorganism was unknown and in one patient the suspected source of entry was the gastrointestinal tract. In three patients there was also concomitant Klebsiella pneumoniae bacteremia. The mean duration of antibiotic treatment was seven weeks and the mean duration of hospital stay was 13.5 days. CONCLUSIONS Liver abscess should always be included in the differential diagnosis in cases of sepsis without obvious source and/or in the clinical scenarios of fever, abdominal pain, and liver lesions.

    Although substitution therapy with opiate agonist treatments such as methadone and buprenorphine has resulted in a reduction of illicit drug use related harm, such treatment has also resulted in severe problems in some countries where opioid-dependent individuals now inject illicitly sold buprenorphine or buprenorphine-naloxone instead of heroin. There is no approved treatment for buprenorphine dependence. Naltrexone is an opioid antagonist which has been used for the treatment of both alcohol and opioid dependencies. Although both buprenorphine and heroin resemble each other concerning their effects, buprenorphine has a higher affinity to opioid receptors than heroin. Therefore, it is not known if naltrexone can block the psychoactive effects of buprenorphine as it does for heroin. This paper presents observational case series data on the use of a sustained-release naltrexone implant for the treatment of buprenorphine dependence. To the authors' knowledge this is the first use of sustained-release naltrexone for this indication. © The Author(s) 2014.

    We investigated the association between particulate matter less than 10 µm in aerodynamic diameter (PM₁₀) exposure and non-accidental mortality in Asian populations by meta-analysis, using both time-series and case-crossover analysis. Among the 819 published studies searched from PubMed and EMBASE using key words related to PM₁₀ exposure and non-accidental mortality in Asian countries, 8 time-series and 4 case-crossover studies were selected for meta-analysis after exclusion by selection criteria. We obtained the relative risk (RR) and 95% confidence intervals (CI) of non-accidental mortality per 10 µg/m³ increase of daily PM₁₀ from each study. We used Q statistics to test the heterogeneity of the results among the different studies and evaluated for publication bias using Begg funnel plot and Egger test. Testing for heterogeneity showed significance (p<0.001); thus, we applied a random-effects model. RR (95% CI) per 10 µg/m³ increase of daily PM₁₀ for both the time-series and case-crossover studies combined, time-series studies relative risk only, and case-crossover studies only, were 1.0047 (1.0033 to 1.0062), 1.0057 (1.0029 to 1.0086), and 1.0027 (1.0010 to 1.0043), respectively. The non-significant Egger test suggested that this analysis was not likely to have a publication bias. We found a significant positive association between PM₁₀ exposure and non-accidental mortality among Asian populations. Continued investigations are encouraged to contribute to the health impact assessment and public health management of air pollution in Asian countries.

    46,XX male sex reversal syndrome is one of the rarest sex chromosomal aberrations. The presence of SRY gene on one of the X chromosomes is the most frequent cause of this syndrome. Based on Y chromosome profile, there are SRY-positive and SRY-negative forms. The purpose of our study was to report first case series of Iranian patients and describe the different clinical appearances based on their genetic component. From the 8,114 azoospermic and severe oligozoospermic patients referred to Royan institute, we diagnosed 57 cases as sex reversal patients. Based on the endocrinological history, we performed karyotyping, SRY and AZF microdeletion screening. Patients had a female karyotype. According to available hormonal reports of 37 patients, 16 cases had low levels of testosterone (43.2%). On the other hand, 15 males were SRY positive (90.2%), while they lacked the spermatogenic factors encoding genes on Yq. Commencing the testicular differentiation in males, the SRY gene is considered to be very important in this process. Due to homogeneous results of karyotyping and AZF deletion, there are both positive and negative SRY cases that show similar sex reversal phenotypes. Evidences show that there could be diverse phenotypic differences that could be raised from various reasons. © 2016 Blackwell Verlag GmbH.

    The purpose was to illustrate the variability of hormonal contraception of patients that presented with membranous dysmenorrheal. A case analysis chart review was completed on six patients referred to a Pediatric Gynecologist in an academic setting. In each case the patient underwent a thorough pelvic and bimanual exam. Following the initial presentation, each patient continued to be followed on a regular visits. Cases: Two were using the transdermal contraceptive patch and oral contraceptive, but following the expulsion of decidual cast, they were both placed on depot medroxyprogesterone acetate (DMPA) without further complications. Three of the six cases were on DMPA prior to the similar occurrence of membranous dysmenorrheal and following this incident, continued on DMPA without further problems. The final case was on the transdermal patch prior to decidual cast expulsion and remained on this form of hormonal contraception without further complications. These cases indicate that membranous dysmenorrheal is not limited to the use of DMPA. PMID:18060329

    Background Poppers are a recreational substance of abuse belonging to the alkyl nitrite family of compounds. In the United Kingdom, where they are legal to purchase but illegal to sell for human consumption, 10% of the general population have tried them. They are considered low risk to physical and mental health. Two recent case series from France demonstrated foveal pathology in individuals associated with poppers use. Method A case series of seven patients presenting to four hospitals in the United Kingdom with visual impairment and maculopathy associated with inhalation of poppers. Results All patients experienced visual symptoms associated with poppers use. The majority had impaired visual acuity, central scotomata, distortion, or phosphenes. Clinical signs on fundoscopy ranged from normal foveal appearance to yellow, dome-shaped lesions at the foveola. Spectral domain optical coherence tomography (SD-OCT) showed varying degrees of disruption of the presumed inner segment/outer segment (IS/OS) junction. Discussion Although poppers have been in use for several decades, in 2007, following legislative changes, there was a change in the most commonly used compound from isobutyl nitrite to isopropyl nitrite. There were no reports of ‘poppers maculopathy' before this. Poppers maculopathy may be missed if patients are not directly questioned about their use. The disruption or loss of the presumed IS/OS junction on SD-OCT are a characteristic feature. Further study of maculopathy in poppers users is now needed. Raising public awareness of the ocular risks associated with their use may be necessary. PMID:23079752

  12. Diagnostic challenges of early Lyme disease: Lessons from a community case series

    PubMed Central

    2009-01-01

    Background Lyme disease, the most common vector-borne infection in North America, is increasingly reported. When the characteristic rash, erythema migrans, is not recognized and treated, delayed manifestations of disseminated infection may occur. The accuracy of diagnosis and treatment of early Lyme disease in the community is unknown. Methods A retrospective, consecutive case series of 165 patients presenting for possible early Lyme disease between August 1, 2002 and August 1, 2007 to a community-based Lyme referral practice in Maryland. All patients had acute symptoms of less than or equal to 12 weeks duration. Patients were categorized according to the Centers for Disease Control and Prevention criteria and data were collected on presenting history, physical findings, laboratory serology, prior diagnoses and prior treatments. Results The majority (61%) of patients in this case series were diagnosed with early Lyme disease. Of those diagnosed with early Lyme disease, 13% did not present with erythema migrans; of those not presenting with a rash, 54% had been previously misdiagnosed. Among those with a rash, the diagnosis of erythema migrans was initially missed in 23% of patients whose rash was subsequently confirmed. Of all patients previously misdiagnosed, 41% had received initial antibiotics likely to be ineffective against Lyme disease. Conclusion For community physicians practicing in high-risk geographic areas, the diagnosis of Lyme disease remains a challenge. Failure to recognize erythema migrans or alternatively, viral-like presentations without a rash, can lead to missed or delayed diagnosis of Lyme disease, ineffective antibiotic treatment, and the potential for late manifestations.

    Williams, Adam David; Osborn, Douglas; Jones, Katherine A.

    To support more rigorous analysis on global security issues at Sandia National Laboratories (SNL), there is a need to develop realistic data sets without using "real" data or identifying "real" vulnerabilities, hazards or geopolitically embarrassing shortcomings. In response, an interdisciplinary team led by subject matter experts in SNL's Center for Global Security and Cooperation (CGSC) developed a hypothetical case description. This hypothetical case description assigns various attributes related to international SNF transportation that are representative, illustrative and indicative of "real" characteristics of "real" countries. There is no intent to identify any particular country and any similarity with specific real-world eventsmore » is purely coincidental. To support the goal of this report to provide a case description (and set of scenarios of concern) for international SNF transportation inclusive of as much "real-world" complexity as possible -- without crossing over into politically sensitive or classified information -- this SAND report provides a subject matter expert-validated (and detailed) description of both technical and political influences on the international transportation of spent nuclear fuel.

    2013-01-01

    The McKenzie method, also known as Mechanical Diagnosis and Therapy (MDT), is primarily recognized as an evaluation and treatment method for the spine. However, McKenzie suggested that this method could also be applied to the extremities. Derangement is an MDT classification defined as an anatomical disturbance in the normal resting position of the joint, and McKenzie proposed that repeated movements could be applied to reduce internal joint displacement and rapidly reduce derangement symptoms. However, the current literature on MDT application to shoulder disorders is limited. Here, we present a case series involving four patients with chronic shoulder pain from a duration of 2–18 months classified as derangement and treated using MDT principles. Each patient underwent mechanical assessment and was treated with repeated movements based on their directional preference. All patients demonstrated rapid and clinically significant improvement in baseline measures and the disabilities of the arm, shoulder, and hand (QuickDASH) scores from an average of 38% at initial evaluation to 5% at discharge within 3–5 visits. Our findings suggest that MDT may be an effective treatment approach for shoulder pain. PMID:24421633

    To report 45 cases of late traumatic flap complications after laser-assisted in situ keratomileusis (LASIK) and discuss the continually increasing number of cases in China. A multicentre retrospective survey of eye injuries was carried in 31 military hospitals from January 2006 to December 2011. Detailed information from the medical records of all 92 cases with a history of prior LASIK treatment were collected and summarised, with respect to visual acuity (VA), flap condition, treatment and final outcome. All Chinese publications relevant to late traumatic flap complications in Chinese patients were retrieved and summarised. 92 inpatients (92 eyes) underwent LASIK surgery; 45 of these had traumatic LASIK flap complications. Flap dislocation was the commonest and most needed surgical repair. VA after treatment was good and no statistically significant difference was observed when compared with the 47 cases without flap complications. 109 articles related to late traumatic flap complications after LASIK were retrieved from four Chinese document databases. There were 550 cases of late traumatic flap complications. From 2004, case reports became more common; 10 or more cases were reported in some case series. VA of most cases was good and there was no remarkable vision loss after treatment. Late traumatic flap complications after LASIK have become more frequent in China, although the prognosis of most cases is good. Published by the BMJ Publishing Group Limited.

    The objective of this study was to analyze a series of traumatic spinal cord injury (SCI) patients with a diagnosis of syrinx who had recurrence of symptomatic syrinx following surgical intervention. This is a patient series. The study was conducted in an acute inpatient rehabilitation facility. Participants included patients ( N =6) with post-traumatic syringomyelia (PTS) who had recurrent syrinx despite surgical repair. Not applicable. The main outcome measures were time period between injury and clinical manifestations of syringomyelia, time to recurrence and presenting symptoms. Among the six patients, there is great variability between time of the initial SCI and the development of syrinx. In terms of time periods between diagnosis of syrinx and recurrence of syrinx, there is also some variability (ranging from 6 to 936 weeks). The median length of time to recurrence was 104 weeks. In all cases, the presenting symptom was ultimately weakness, and in most cases it was associated with rising sensory deficits. Notably, all patients were male, aged 31-55 years, had suffered diffuse traumatic SCI and four of six patients lost the ability to ambulate because of syrinx formation. This series suggests that there may be risk factors for developing post-traumatic syringomyelia. We question whether there is a relationship between American Spinal Injury Association Impairment Scale grade and recurrence of PTS. We need to look closely at these patients to see whether there are modifiable risk factors that may minimize their chance of developing PTS. Once these are identified, there may be a role in routine screening of all patients and particularly those who may be at an increased risk for PTS to avoid loss of ambulatory function.

    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. 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. 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 vitamin D supplementation for reducing breast

Although with warfarin the rate of stroke reduced notably, the major concern is the risk of serious bleeding and difficulty of establishing and maintaining the international normalised ratio (INR) within the therapeutic range. With the development of the novel anticoagulants we now have for the first time since the innovation of Warfarin feasible alternatives to it to decrease stroke rates in high risk patients with NVAF. To diminish adverse bleeding events with the novel anticoagulant proper selection of patients prior starting treatment is essential. Crown Copyright © 2013. Published by Elsevier B.V.

    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.

    To describe the biopsychosocial characteristics of a series of Pacific men living in South Auckland with a history of boxing presenting with early onset dementia. We discuss the history of boxing in Pacific people and the possibility of increased risk of early onset dementia in New Zealand Pacific men compared to their European counterparts. We reviewed the files of Pacific men with a history of amateur or professional boxing who presented to our memory and older adult mental health services with early onset dementia over a 45-month period. We gathered relevant information to construct a biopsychosocial paradigm as possible explanation of this phenomenon. We identified a series of eight New Zealand Pacific men with early onset dementia and with a history of boxing. Alcohol was a contributing factor in seven of the eight cases, and vascular risk factors in five. Historical, cultural and socio-economic factors underpin the attraction of some Pacific men to boxing as a sport. Given that New Zealand Pacific peoples may have an earlier onset of dementia than their European counterparts, further research is required to establish whether boxing is a contributory factor. Sports physicians should advise young New Zealand Pacific boxers about the long-term risks associated with their sport.

    The mortality of pregnant women with idiopathic pulmonary arterial hypertension (PAH) is very high. There are limited data on the management of idiopathic PAH during pregnancy. The authors aimed to examine systematically the characteristics of parturient women with idiopathic PAH, to explore the adverse effects of idiopathic PAH on pregnancy outcomes, and to report the multidisciplinary perioperative management strategy from the largest comprehensive cardiac hospital in China. Observational case series study. Tertiary referral acute care hospital in Beijing, China. The cases of 17 consecutive pregnant idiopathic PAH patients undergoing abortion or parturition at Anzhen Hospital were reviewed retrospectively. Preoperative characteristics, anesthesia method, intensive care management, PAH-specific therapy, and maternal and neonatal outcomes were analyzed in this case series study. Maternal and neonatal outcomes were the main measures. The mean ages of the 17 parturient women with idiopathic PAH were 28.3 ± 5.4 years, and the mean systolic pulmonary arterial pressure was 97.9 ± 18.6 mmHg. Fifteen patients (88.2%) received PAH-specific therapy before delivery, including sildenafil, iloprost, and treprostinil. All except 1 parturient received epidural anesthesia for surgery due to an emergency Caesarean section. Three patients experienced pulmonary hypertension crisis that necessitated conversion to general anesthesia. Ten parturients underwent Caesarean delivery at a median gestational age of 31 weeks. Three patients developed acute pulmonary hypertensive crisis intraoperatively. Two patients underwent cardiopulmonary resuscitation and extracorporeal membrane oxygenation support. The maternal mortality was 17.6% (3/17). Of the 10 delivered neonates, 9 (90.0%) survived. The maternal mortality of the idiopathic PAH parturient was high in this case series from China.

    Nonobstructive hydrocephalus in patients with craniopharyngiomas is uncommon. We describe our surgical series of 25 consecutive patients with craniopharyngioma who presented with hydrocephalus. Obstructive hydrocephalus was evident in most cases, and nonobstructive hydrocephalus was revealed in three cases. Even after improvement of cerebrospinal fluid (CSF) pathway obstruction by tumor removal, 10 patients (40%) required CSF diversion. Preoperative imaging study revealed thin intraventricular hemorrhage or superficial siderosis in five cases, and CSF examination revealed hemosiderin-laden phagocytes in one case. These findings indicate continuous bleeding into the CSF that might be associated with CSF malabsorption. We also describe a representative case of craniopharyngioma associated with nonobstructive hydrocephalus due to continuous minor bleeding from the tumor surface in a 62-year-old man with a complaint of disorientation and a decline in daily living activity.Our study demonstrated that minor bleeding into the CSF is a possible mechanism of the development of nonobstructive hydrocephalus in patients with craniopharyngiomas.

    Severe pelvic trauma remains associated with elevated mortality, largely due to hemorrhagic shock. The main study objective was to test for correlation between fracture type and mortality. The secondary objective was to assess the efficacy in terms of mortality of multidisciplinary management following a decision-tree in multiple trauma victims admitted to a level 1 trauma center. Between July 2011 and July 2013, 534 severe trauma patients were included in a single-center continuous prospective observational study. All patients with hemorrhagic shock received early treatment by pelvic binder. Patients with active bleeding on full-body CT or persisting hemorrhagic shock underwent arteriography with or without embolization. Pelvic trauma was graded on the Tile classification. The principle end-point was mortality. Median age was 40 years (range, 26-48 years), with a 79% male/female sex ratio. Thirty-two of the 67 patients with pelvic trauma (48%) were in hemorrhagic shock at admission. Median injury severity score (ISS) was 36 (range, 24-43). On the Tile classification, 22 patients (33%) were grade A, 33 (49%) grade B and 12 (18%) grade C. Overall mortality was 19%, and 42% in case of hemorrhagic shock. Mortality was significantly higher with Tile C than A or B (58% vs. 9.1% and 12.1%, respectively; P=0.001). Vertical shear fracture (Tile C) was associated with greater mortality from hemorrhagic shock. IV, case series. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Left-sided and duplicate inferior vena cava (IVC) are two major anatomical variants within the spectrum of IVC malformations, both of which are developmental abnormalities of the supracardinal veins. Four clinical cases are described to highlight the computed tomographic appearances of these vascular malformations and provide novel data on venous dimensions. A systematic review of the recent literature (2000-2011) was conducted focusing on the anatomy, demographics, and associated pathology (congenital and acquired) of isolated left-sided and duplicate IVC. A total of 73 relevant articles were retrieved, consisting of case reports and small case series. The prevalence of left-sided IVC is about 0.1-0.4% and that for duplicate IVC about 0.3-0.4%; both anomalies show a slight male preponderance. In each condition, there are documented variations in the course and tributaries of the IVC. The clinical importance of these anomalies lies in three principal areas: the potential for misdiagnosis on imaging; technical difficulties during retroperitoneal surgery (particularly abdominal aortic aneurysm repair and live donor nephrectomy); and their significance in relation to the etiology and management of venous thromboembolism.

    An estimated 3700 individuals are seen annually in US emergency departments for nail gun-related injuries. Approximately 45 cases have been reported in the literature concerning nail gun injuries penetrating the cranium. These cases pose a challenge for the neurosurgeon because of the uniqueness of each case, the dynamics of high pressure nail gun injuries, and the surgical planning to remove the foreign body without further vascular injury or uncontrolled intracranial hemorrhage. Here we present four cases of penetrating nail gun injuries with variable presentations. Case 1 is of a 33-year-old white man who sustained 10 nail gunshot injuries to his head. Case 2 is of a 51-year-old white man who sustained bi-temporal nail gun injuries to his head. Cases 3 and 4 are of two white men aged 22 years and 49 years with a single nail gun injury to the head. In the context of these individual cases and a review of similar cases in the literature we present surgical approaches and considerations in the management of nail gun injuries to the cranium. Case 1 presented with cranial nerve deficits, Case 2 required intubation for low Glasgow Coma Scale, while Cases 3 and 4 were neurologically intact on presentation. Three patients underwent angiography for assessment of vascular injury and all patients underwent surgical removal of foreign objects using a vice-grip. No neurological deficits were found in these patients on follow-up. Nail gun injuries can present with variable clinical status; mortality and morbidity is low for surgically managed isolated nail gun-related injuries to the head. The current case series describes the surgical use of a vice-grip for a good grip of the nail head and controlled extraction, and these patients appear to have a good postoperative prognosis with minimal neurological deficits postoperatively and on follow-up.

  10. Generalized seasonal autoregressive integrated moving average models for count data with application to malaria time series with low case numbers.

    With the renewed drive towards malaria elimination, there is a need for improved surveillance tools. While time series analysis is an important tool for surveillance, prediction and for measuring interventions' impact, approximations by commonly used Gaussian methods are prone to inaccuracies when case counts are low. Therefore, statistical methods appropriate for count data are required, especially during "consolidation" and "pre-elimination" phases. Generalized autoregressive moving average (GARMA) models were extended to generalized seasonal autoregressive integrated moving average (GSARIMA) models for parsimonious observation-driven modelling of non Gaussian, non stationary and/or seasonal time series of count data. The models were applied to monthly malaria case time series in a district in Sri Lanka, where malaria has decreased dramatically in recent years. The malaria series showed long-term changes in the mean, unstable variance and seasonality. After fitting negative-binomial Bayesian models, both a GSARIMA and a GARIMA deterministic seasonality model were selected based on different criteria. Posterior predictive distributions indicated that negative-binomial models provided better predictions than Gaussian models, especially when counts were low. The G(S)ARIMA models were able to capture the autocorrelation in the series. G(S)ARIMA models may be particularly useful in the drive towards malaria elimination, since episode count series are often seasonal and non-stationary, especially when control is increased. Although building and fitting GSARIMA models is laborious, they may provide more realistic prediction distributions than do Gaussian methods and may be more suitable when counts are low.

    Moyamoya disease is a cerebral vasculopathy characterized by stenosis of the terminal internal carotid artery, proximal middle cerebral artery, and anterior cerebral artery. There is an association between moyamoya vasculopathy and Graves disease, primarily in Asian populations. Here, we present the largest series of non-Asian, predominantly Latino patients with moyamoya vasculopathy in the setting of Graves thyrotoxicosis, as well as the largest review of the literature to date. We retrospectively analyzed patients presenting with stroke in the setting of clinical Graves disease to our institution from 2004 to 2014. Moyamoya vasculopathy was diagnosed by magnetic resonance angiography in all patients. Eight patients with Graves disease thyrotoxicosis and moyamoya vasculopathy were identified. Six patients were effectively managed with aggressive medical management using antithyroid and antiplatelet medications. No recurrent strokes were noted once thyrotoxicosis was controlled. Intracranial bypass was necessary in 2 patients who failed medical management. Seventy-nine additional cases were reported from the literature. There was no significant difference in clinical improvement between medical therapy alone and medical therapy with neurosurgical prophylaxis (87.0% vs. 88.0%, respectively; P = 0.94). Moyamoya vasculopathy associated with Graves disease thyrotoxicosis in non-Asian women may be more common than previously thought. In addition, our series suggests that thyrotoxicosis promotes the progression of vasculopathy. Based on our review, there is no significant difference in clinical improvement between proper medical and surgical therapies. Aggressive medical therapy should be considered first-line treatment for moyamoya vasculopathy with Graves thyrotoxicosis, with neurosurgical rescue reserved for medically refractory cases.

    Recent advances in multimedia and mobile technologies have facilitated large volumes of travel photos to be created and shared online. Although previous studies have utilized geotagged photos to model travel patterns at individual locations, there is limited research on how these datasets can model international travel behavior and inter-country travel flows—a crucial indicator to quantify the interactions between countries in tourism economics. Realizing the necessity to investigate the potential of geotagged photos in tourism geography, this research investigates international travel patterns from two perspectives: 1) We apply a series of indicators (radius of gyration (ROG), number of countries visited, and entropy) to measure the descriptive characteristics of international travel in different countries; 2) By constructing a gravity model of trade, we investigate how distance decay influences the magnitude of international travel flow between geographic entities, and whether (or how much) the popularity of a given destination (defined as the percentage of tourist income in national gross domestic product (GDP)) affects travel choices in different countries. The results provide valuable input to various commercial applications such as individual travel planning and destination suggestions. PMID:27159195

    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.

     Hydrocephalus can be progressive or spontaneously arrested. In arrested hydrocephalus, the balance between production and absorption of the cerebrospinal fluid is restored. Patients are mostly asymptomatic, and no surgical treatment is necessary for them.  We performed a two-center consecutive case series study, aimed at investigating the safety of nonsurgical management of hydrocephalus in selected pediatric patients. We retrospectively selected all consecutive patients, suspected to suffer from arrested hydrocephalus and referred to our two institutions between January 2011 and December 2013. Data on clinical and radiological follow-up were collected until June 2017.  Five children diagnosed with arrested hydrocephalus were included in the study. All patients presented macrocephaly as the main presenting sign. Associated mild-to-moderate stable motor disorders were assessed in four out of five cases. Typical symptoms and signs associated with acute raised intracranial pressure were absent in all patients. Magnetic resonance imaging studies showed ventriculomegaly in all patients. A diagnosis of arrested hydrocephalus was made in all five cases based on stable clinical and radiological findings during the initial observation. Conservative management based on active surveillance was, therefore, proposed. During the follow-up period, we observed stable or improved conditions in four out of five patients, while the remaining patient presented progressive hydrocephalus.  Making a distinction between arrested and progressive hydrocephalus is fundamental, because of the opposed appropriate management. Any newly discovered case of hydrocephalus, not characterized by clear signs of progressive hydrocephalus, should benefit from active surveillance before any definitive decision is taken.

    Case series. Ankle fractures commonly result in persistent pain, stiffness, and functional impairments. There is insufficient evidence to favor any particular rehabilitation approach after ankle fracture. The purpose of this case series was to describe an impairment-based manual physical therapy approach to treating patients with conservatively managed ankle fractures. Patients with stable ankle fractures postimmobilization were treated with manual physical therapy and exercise targeted at associated impairments in the lower limb. The primary outcome measure was the Lower Extremity Functional Scale. Secondary outcome measures included the ankle lunge test, numeric pain-rating scale, and global rating of change. Outcome measures were collected at baseline (performed within 7 days of immobilization removal) and at 4 and 12 weeks postbaseline. Eleven patients (mean age, 39.6 years; range, 18-64 years; 2 male), after ankle fracture-related immobilization (mean duration, 48 days; range, 21-75 days), were treated for an average of 6.6 sessions (range, 3-10 sessions) over a mean of 46.1 days (range, 13-81 days). Compared to baseline, statistically significant and clinically meaningful improvements were observed in Lower Extremity Functional Scale score (P = .001; mean change, 21.9 points; 95% confidence interval: 10.4, 33.4) and in the ankle lunge test (P = .001; mean change, 7.8 cm; 95% confidence interval: 3.9, 11.7) at 4 weeks. These changes persisted at 12 weeks. Statistically significant and clinically meaningful improvements in self-reported function and ankle range of motion were observed at 4 and 12 weeks following treatment with impairment-based manual physical therapy. All patients tolerated treatment well. Results suggest that this approach may have efficacy in this population. Therapy, level 4.

    To evaluate the efficacy and safety of a novel surgical approach, ab interno trabeculectomy, in a combined procedure (clear corneal phacoemulsification + ab interno trabeculectomy) for the management of concurrent cataract and glaucoma with prognostic factors for filtration failure. Department of Ophthalmology, Palmanova Hospital, Udine, Italy. A prospective noncomparative case series of 11 eyes of 11 consecutive cataract patients with medically uncontrolled primary open-angle glaucoma or pseudoexfoliation glaucoma was performed. Each patient had phacoemulsification + intraocular lens implantation + ab interno trabeculectomy, which consisted of a gonioscopically controlled ab interno removal of a quadrant (3 clock hours) of the trabecular meshwork. The main outcome measures were intraocular pressure (IOP), the number of antiglaucomatous medications used, and complications. Ten patients completed a 3-year follow-up. One patient had further surgery because of poor IOP control; in this case, the last valid observation was carried forward for IOP calculation. Mean preoperative IOP and IOPs measured 1, 3, 6, 12, 24, and 36 months after surgery were 25.0, 15.8, 15.4, 15.4, 15.2, 15.0, and 15.3 (-38.56%) mm Hg respectively. The number of medications averaged 2.4 before surgery and dropped to 0.8 at the end of follow-up. No major complications occurred during the follow-up period. The new surgical procedure combining phacoemulsification with ab interno trabeculectomy can induce a clinically relevant decrease in IOP in eyes with cataract and glaucoma with poor prognosis for filtering surgery. However, a randomized controlled clinical trial with a more extended follow-up and a larger series of patients is needed to ascertain the actual effectiveness and safety of this procedure.

    Vancomycin-resistant enterococci are a leading cause of hospital-acquired urinary tract infection and a growing concern for the clinician. The aim of this study was to evaluate the effectiveness of daptomycin in the treatment of patients with vancomycin-resistant enterococcal urinary tract infection treated in our 200-bed community-based institution. Patients with confirmed symptomatic vancomycin-resistant enterococcal urinary tract infection identified by infectious disease consultation between January 1, 2007, and December 8, 2009, vancomycin-resistant enterococci-positive urine culture, and urinary symptoms and/or pyuria on urinalysis, and treated with daptomycin, were included in this case series. Daptomycin was generally administered at a planned dosage regimen of ≥ 5 mg/kg every 24 hours in patients with normal to moderately impaired kidney function or every 48 hours in patients with severe kidney disease. Microbiologic cure was defined as eradication of vancomycin-resistant enterococci in urine cultures taken after the completion of daptomycin treatment. Clinical cure was defined by symptom resolution, as assessed by the infectious disease clinician caring for the patient. Included in this case series are 10 patients who received daptomycin for confirmed vancomycin-resistant enterococcal urinary tract infection. Patients had a history of extensive hospital stays. Chart review revealed that all levels of kidney function (3, 2, 3, and 2 patients with kidney disease classified as normal, mild, moderate, and severe/kidney failure, respectively) were represented in the sample and that patients with (n = 5) or without (n = 5) previous urinary tract infection and with (n = 3) or without (n = 7) Foley catheters were included. Treatment with daptomycin achieved clinical cure and vancomycin-resistant enterococcal eradication in all cases in this series. Treatment with daptomycin was well tolerated and effective in all patients in this series, regardless of renal

    Acute kidney injury is rarely the presenting feature of sarcoidosis. We present a case series of patients whose diagnosis of sarcoidosis was only brought to light by the development of renal impairment. Concurrent hypercalcaemia was noted, prompting further investigation. The patients discussed experienced a significant and rapid improvement in both renal function and hypercalcaemia in response to therapy with prednisolone. This is out of keeping with previous reports of sarcoidosis-induced renal impairment. Our case series highlights the importance of testing for hypercalcaemia in the context of acute kidney injury. Sarcoidosis is primarily a disease of the lungs and reticuloendothelial system; however, the prevalence of renal involvement with sarcoidosis may be under-recognized. The renal manifestations of sarcoidosis are discussed in the context of the current literature. Furthermore, from our experience, we postulate that in the context of sarcoidosis-induced renal injury, concurrent hypercalcaemia may present prior to the development of chronic renal injury and therefore these patients may be more likely to recover renal function. © 2017 Asian Pacific Society of Nephrology.

    Strongyloidiasis infects hundreds of millions of people worldwide and is an important cause of mortality from intestinal helminth infection in developed countries. The persistence of infection, increasing international travel, lack of familiarity by health care providers, and potential for iatrogenic hyperinfection all make strongyloidiasis an important emerging infection. Two studies were performed. A retrospective chart review of Strongyloides stercoralis cases identified through microbiology laboratory records from 1993-2002 was conducted. Subsequently, 363 resident physicians in 15 training programs worldwide were queried with a case scenario of strongyloidiasis, presenting an immigrant with wheezing and eosinophilia. The evaluation focused on resident recognition and diagnostic recommendations. In 151 strongyloidiasis cases, stool ova and parasite sensitivity is poor (51%), and eosinophilia (>5% or >400 cells/microL) commonly present (84%). Diagnosis averaged 56 months (intra-quartile range: 4-72 months) after immigration. Presenting complaints were nonspecific, although 10% presented with wheezing. Hyperinfection occurred in 5 patients prescribed corticosteroids, with 2 deaths. Treatment errors occurred more often among providers unfamiliar with immigrant health (relative risk of error: 8.4; 95% confidence interval, 3.4-21.0; P <.001). When presented with a hypothetical case scenario, US physicians-in-training had poor recognition (9%) of the need for parasite screening and frequently advocated empiric corticosteroids (23%). International trainees had superior recognition at 56% (P <.001). Among US trainees, 41% were unable to choose any parasite causing pulmonary symptoms. Strongyloidiasis is present in US patients. Diagnostic consideration should occur with appropriate exposure, nonspecific symptoms including wheezing, or eosinophilia (>5% relative or >400 eosinophils/microL).

    The aim of this study is to assess the outcome of conservative management of infected mesh grafts following abdominal wall hernia repair. This study retrospectively examined the charts of patients who developed mesh-site infection following surgery for abdominal hernia repair to determine how effective conservative management in the form of antibiotics and wound management was on the resolution of infection and wound healing. Over a period of 30 months, 13 patients developed infected mesh grafts post-hernia repair surgery. Twelve patients were successfully treated conservatively with local wound care and antibiotics if clinically indicated. One patient returned to theatre to have the infected mesh removed. Of the patients that healed eleven were treated with negative pressure wound therapy (VAC(®)). This series of case studies indicate that conservative management of abdominal wall-infected hernia mesh cases is likely to be successful.

    To present a mucopolysaccharidosis (MPS) case series evaluating oral manifestations (clinical and radiographic), oral health status and discussing its implications. All patients with MPS attending the Genetics clinic/Brazil were evaluated by means of anamnesis, clinical and radiographic examinations. The final sample consisted of 12 subjects (nine males and three females), with ages ranging from 3-31 years old. Concerning oral health, it was observed high levels of caries and periodontal problems. About oral manifestations, this study clinically observed more cases of delayed tooth eruption, thickness of alveolar process and thick lips. Radiographically, it was observed alterations on condyle, mandibular ramus and joint fossa. The dental changes in MPS population are high and consequently it is important to know them for differential diagnoses, early treatment intervention, prevention and education of both patients and parents/caregivers about oral health.

    Discolouration of teeth, especially the anteriores, can result in considerably cosmetic impairment in person. Combine effects of intrinsic and extrinsic colour determines the appearance of teeth. Whitening of teeth with bleaching is a more conservative therapeutic method than full crowns, veneers or composite restorations which is more invasive and expensive. Among bleaching techniques, in office bleaching with carbamide peroxide provide superior aesthetic result in short period of time with no adverse effects. This paper presents case series of tooth discolouration in non-vital tooth which was successfully bleached using 35 % carbamide peroxide. After 1 year follow up the prognosis was good with no reversal of tooth discolouration. This case report allows the better understanding of the concept of nonvital tooth bleaching with carbamide peroxide which gives a non-invasive alternative for aesthetic purpose in preserving the natural tooth structure.

    Brazilian spotted fever (BSF) is the most important tick-borne disease in Brazil and is caused by Rickettsia rickettsii and transmitted by the Ixodid tick Amblyomma cajennense, its main vector. We present epidemiologic aspects of a case series of patients admitted to the Hospital das Clínicas da UNICAMP from 1985 to 2003 with a confirmed diagnosis of BSF either by a fourfold rise in indirect immunofluorescence (IFA) titers of IgG antibodies reactive with R. rickettsii or isolation of R. rickettsii from blood or skin specimens. Seasonal variation of case occurrence seems to be associated with the life cycle of the tick. The recent reemergence of cases seems to be associated with the growing numbers of the capybara (Hydrochaeris hydrochaeris) and their expansion into urban areas.

    We present a series of 146 cases of hepatic trauma (HT) treated in our hospital over a period of 8 yearsm (2001-2008), and comparing it with a previous series of 92 cases (1977-1984). The mean age in the current series was 28.6 years and the majority were male. The closed traumas were mainly penetrating, with the most frequent cause being road traffic accidents. The American Association for the Surgery of Trauma (AAST) classification was used to evaluate the grade of the hepatic injury. Associated abdominal and /or extra-abdominal injuries were seen in 79.5% of the patients, with the most frequent being chest trauma, compared to bone fractures in the previous series. The most common associated intra-abdominal injury was the spleen in both series. The most used diagnostic technique in the current series was abdominal CT. Simple peritoneal puncture and lavage (PLP) were the most used examinations used in the previous series. Non-surgical treatment (NST) was given in 98 cases and the surgery was indicated in the remaining 48. In the previous series, 97.8% of patients were operated on. In the current series, on the 15 patients with severe liver injuries, 5 right hepatectomies, 2 segmentectomies and 6 packing compressions were performed, with the remaining two dying during surgery due to hepatic avulsion. The overall mortality was 3.4%, being 1% in the NST group and 8.3% in the surgical patients. In the previous series, the overall mortality was 29.3%. The key factor for using NST is to control haemodynamic stability, leaving surgical treatment for haemodynamically unstable patients. Copyright © 2011 AEC. Published by Elsevier Espana.

    (68)Ga-DOTATATE PET-CT is widely used for the evaluation of neuroendocrine tumours. Knowledge of the physiological distribution of the radiotracer is of critical importance in characterizing focal areas of uptake. In this case series, we report three paediatric cases (average age 4.7 years ± 0.6 SD) with diagnosed advanced stage IV Neuroblastoma. Two had (68)Ga-DOTATATE PET-CT scans and one underwent (68)Ga-DOTATATE PET-MRI scan to assess for suitability of molecular therapy. Focal increased tracer uptake in the pineal gland was noted in all cases with no morphological abnormality on the corresponding CT and MRI scans. The uptake within the gland was thought to be a physiological variant rather than metastases owing to the heterogeneity of somatostatin receptors expression. The pineal gland has been reported to express somatostatin receptors. The physiological distribution of (68)Ga-DOTATATE uptake in the pineal gland is not routinely seen. Furthermore, the possibility of pineal meningioma is very unlikely as pineal meningiomas are very rare and there was no convincing morphological evidence of meningiomas on CT/MRI scan.

Case series of patients with Behçet's Disease who presented to a clinical practice devoted to Pain Medicine and Neurology between 2000 and 2009 for treatment of myalgia. All patients were treated with prednisone 60 mg by mouth daily for exacerbations of their disease. When this failed, eleven patients received intravenous administration of amino acids (Procalamine). Ten of eleven patients had a complete resolution of their Behçet's exacerbation, including myalgia; their painful ulcers became painless and began to heal with the infusion of amino acids for 2-5 days. Physicians treating myalgia should observe for signs of Behçet's disease, such as oral and genital ulcerations, and consider intravenous amino acids if steroids are not effective.

    This retrospective case series analyzed 45 malpractice claims for delayed detection of esophageal intubation from the Anesthesia Closed Claims Project. Inclusion criteria were cases from 1995 to 2013, after adoption of identification of CO2 in expired gas to verify correct endotracheal tube position as a monitoring standard by the American Society of Anesthesiologists. Forty-nine percent (95% confidence interval 34%-64%) occurred in the operating room or other anesthesia location where CO2 detection equipment should have been available. The most common factors contributing to delayed detection were not using, ignoring, or misinterpreting CO2 readings. Misdiagnosis, as with bronchospasm, occurred in 33% (95% confidence interval 20%).

    Mutations in the mitochondrial genome can impair normal metabolic function in the central nervous system (CNS) where cellular energy demand is high. Primary mitochondrial DNA (mtDNA) mutations have been linked to several mitochondrial disorders that have comorbid psychiatric, neurologic, and cognitive sequelae. Here, we present a series of cases with primary mtDNA mutations who were genotyped and evaluated across a common neuropsychological battery. Nineteen patients with mtDNA mutations were genotyped and clinically and cognitively evaluated. Pronounced deficits in nonverbal/visuoperceptual reasoning, verbal recall, semantic word generativity, and processing speed were evident and consistent with a "mitochondrial dementia" that has been posited. However, variation in cognitive performance was noteworthy, suggesting that the phenotypic landscape of cognition linked to primary mtDNA mutations is heterogeneous. Our patients with mtDNA mutations evidenced cognitive deficits quite similar to those commonly seen in Alzheimer's disease and could have clinical relevance to the evaluation of dementia. © The Author 2014.

    Cannabis and its principal active constituent, Δ9-tetrahydrocannabinol (THC), are increasingly available as edibles resembling commercially available food products. In this case series, we describe a population of predominantly pediatric patients who were inadvertently exposed to a THC-containing product in San Francisco. Twelve children and 9 adults were identified, with 16 patients having detectable serum THC and THC metabolites. All patients presented to hospitals with a variety of constitutional symptoms and all were discharged home within 12 hours. In general, pediatric patients had more severe symptoms and longer hospital length of stay, and, uniquely, a majority presented with leukocytosis and elevated lactic acid levels. We recommend that efforts be made to increase general public awareness in regard to the potential hazards of THC-containing edibles resembling commercially available food products.

  16. Generalized Seasonal Autoregressive Integrated Moving Average Models for Count Data with Application to Malaria Time Series with Low Case Numbers

    Introduction With the renewed drive towards malaria elimination, there is a need for improved surveillance tools. While time series analysis is an important tool for surveillance, prediction and for measuring interventions’ impact, approximations by commonly used Gaussian methods are prone to inaccuracies when case counts are low. Therefore, statistical methods appropriate for count data are required, especially during “consolidation” and “pre-elimination” phases. Methods Generalized autoregressive moving average (GARMA) models were extended to generalized seasonal autoregressive integrated moving average (GSARIMA) models for parsimonious observation-driven modelling of non Gaussian, non stationary and/or seasonal time series of count data. The models were applied to monthly malaria case time series in a district in Sri Lanka, where malaria has decreased dramatically in recent years. Results The malaria series showed long-term changes in the mean, unstable variance and seasonality. After fitting negative-binomial Bayesian models, both a GSARIMA and a GARIMA deterministic seasonality model were selected based on different criteria. Posterior predictive distributions indicated that negative-binomial models provided better predictions than Gaussian models, especially when counts were low. The G(S)ARIMA models were able to capture the autocorrelation in the series. Conclusions G(S)ARIMA models may be particularly useful in the drive towards malaria elimination, since episode count series are often seasonal and non-stationary, especially when control is increased. Although building and fitting GSARIMA models is laborious, they may provide more realistic prediction distributions than do Gaussian methods and may be more suitable when counts are low.

    Though neurofibromatosis type I (NFI) is a fairly common condition, it has a variable expressivity and penetrance. Here we present a series of cases with striking differences in the presentation especially in the oral cavity. NFI, also known as von Recklinghausen's neurofibromatosis, is an autosomal dominantly inherited neurogenetic disorder affecting 1:3000 newborn (Bongiorno et al., Oral Dis 12:125-129, 2006). About 50 % of NFI patients have no family history of the disease. There is no prevalence for gender or race in NFI. Expressivity in NFI is tremendously variable, but subtle phenotypic patterns may exist within subgroups of affected patients. Furthermore, 50 % of cases are sporadic and arise from germ cell mutation (Bongiorno et al., Oral Dis 12:125-129, 2006). The precise constellation of findings in any one individual is extremely variable, both within a family and between different families (Batsakis, Tumors of the head and neck: clinical and pathological considerations, 2nd edn. Williams and Wilkins, Baltimore, pp 313-333, 1979). Only 4-7 % of patients affected by neurofibromatosis exhibit oral manifestations (Güneri et al., Turk J Pediatr 48(2):155-158, 2006).

  1. Zolpidem ingestion, automatisms, and sleep driving: a clinical and legal case series.

    2011-12-15

    To describe zolpidem-associated complex behaviors, including both daytime automatisms and sleep-related parasomnias. A case series of eight clinical patients and six legal defendants is presented. Patients presented to the author after an episode of confusion, amnesia, or somnambulism. Legal defendants were being prosecuted for driving under the influence, and the author reviewed the cases as expert witness for the defense. Potential predisposing factors including comorbidities, social situation, physician instruction, concomitant medications, and patterns of medication management were considered. Patients and defendants exhibited abnormal behavior characterized by poor motor control and confusion. Although remaining apparently interactive with the environment, all reported amnesia for 3 to 5 hours. In some cases, the episodes began during daytime wakefulness because of accidental or purposeful ingestion of the zolpidem and are considered automatisms. Other cases began after ingestion of zolpidem at the time of going to bed and are considered parasomnias. Risk factors for both wake and sleep-related automatic complex behaviors include the concomitant ingestion of other sedating drugs, a higher dose of zolpidem, a history of parasomnia, ingestion at times other than bedtime or when sleep is unlikely, poor management of pill bottles, and living alone. In addition, similar size and shape of two medications contributed to accidental ingestion in at least one case. Sleep driving and other complex behaviors can occur after zolpidem ingestion. Physicians should assess patients for potential risk factors and inquire about parasomnias. Serious legal and medical complications can occur as a result of these forms of automatic complex behaviors.

  2. Assessments of higher-order ionospheric effects on GPS coordinate time series: A case study of CMONOC with longer time series

    2014-05-01

    Higher-order ionospheric (HIO) corrections are proposed to become a standard part for precise GPS data analysis. For this study, we deeply investigate the impacts of the HIO corrections on the coordinate time series by implementing re-processing of the GPS data from Crustal Movement Observation Network of China (CMONOC). Nearly 13 year data are used in our three processing runs: (a) run NO, without HOI corrections, (b) run IG, both second- and third-order corrections are modeled using the International Geomagnetic Reference Field 11 (IGRF11) to model the magnetic field, (c) run ID, the same with IG but dipole magnetic model are applied. Both spectral analysis and noise analysis are adopted to investigate these effects. Results show that for CMONOC stations, HIO corrections are found to have brought an overall improvement. After the corrections are applied, the noise amplitudes decrease, with the white noise amplitudes showing a more remarkable variation. Low-latitude sites are more affected. For different coordinate components, the impacts vary. The results of an analysis of stacked periodograms show that there is a good match between the seasonal amplitudes and the HOI corrections, and the observed variations in the coordinate time series are related to HOI effects. HOI delays partially explain the seasonal amplitudes in the coordinate time series, especially for the U component. The annual amplitudes for all components are decreased for over one-half of the selected CMONOC sites. Additionally, the semi-annual amplitudes for the sites are much more strongly affected by the corrections. However, when diplole model is used, the results are not as optimistic as IGRF model. Analysis of dipole model indicate that HIO delay lead to the increase of noise amplitudes, and that HIO delays with dipole model can generate false periodic signals. When dipole model are used in modeling HIO terms, larger residual and noise are brought in rather than the effective improvements.

    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

    Psychosis can be associated with acute recreational drug and novel psychoactive substance (NPS) toxicity. However, there is limited data available on how common this is and which drugs are most frequently implicated. We describe a European case series of psychosis associated with acute recreational drug toxicity, and estimate the frequency of psychosis for different recreational drugs. The European Drug Emergencies Network (Euro-DEN) collects data on presentations to Emergency Departments (EDs) with acute recreational drug and NPS toxicity at 16 centres in ten countries. Euro-DEN data from October 2013 through September 2014 was retrospectively searched, and cases with psychosis were included. The proportion of cases with psychosis per drug was calculated in the searched Euro-DEN dataset. Psychosis was present in 348 (6.3 %) of 5529 cases. The median (interquartile range) age was 29 (24-38) years, 276 (79.3 %) were male and 114 (32.8 %) were admitted to psychiatric ward. The drugs most commonly reported were cannabis in 90 (25.9 %) cases, amphetamine in 87 (25.0 %) and cocaine in 56 (16.1 %). More than one drug was taken in 189 (54.3 %) cases. Psychosis was frequent in those ED presentations involving tryptamines (4/7; 57.1 %), methylenedioxypyrovalerone (MDPV) (6/22; 27.3 %), methylphenidate (6/26; 23.1 %), lysergic acid diethylamide (LSD) (18/86; 20.9 %), psilocybe mushrooms (3/16; 18.8 %), synthetic cannabinoid receptor agonists (4/26; 15.4 %) and amphetamine (87/593; 14.7 %), but less common in those involving mephedrone (14/245; 5.7 %), methylenedioxymethamphetamine (MDMA) (20/461; 4.3 %) and methedrone (3/92; 3.3 %). Amphetamine was the most frequent drug associated with psychosis when only one agent was reported, with psychosis occurring in 32.4 % of these presentations. The frequency of psychosis in acute recreational drug toxicity varies considerably between drugs, but is a major problem in amphetamine poisoning. In rapidly changing drug markets and

    Let Phi be a reduced root system of rank r . A Weyl group multiple Dirichlet series for Phi is a Dirichlet series in r complex variables s_1,dots,s_r , initially converging for {Re}(s_i) sufficiently large, that has meromorphic continuation to {{C}}^r and satisfies functional equations under the transformations of {{C}}^r corresponding to the Weyl group of Phi . A heuristic definition of such a series was given by Brubaker, Bump, Chinta, Friedberg, and Hoffstein, and they have been investigated in certain special cases by others. In this paper we generalize results by Chinta and Gunnells to construct Weyl group multiple Dirichlet series by a uniform method and show in all cases that they have the expected properties.

    Turkana is the largest district in Kenya, situated in the Northwest of the country. It features a semi-nomadic population of 850,000. Around 60% of population lives below the poverty threshold. 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.

    Reconstruction of large diaphyseal bone defect is complex and the complications rate is high. This study aimed to assess a simplified technique of segmental bone transport by monorail external fixator over an intramedullary nail.A prospective study included 7 patients: 2 femoral and 5 tibial defects. Mean age was 31years (range: 16-61years). Mean follow-up was 62 months (range: 46-84months). Defects were post-traumatic, with a mean length of 7.2cm (range: 4 to 9.5cm). For 3 patients, reconstruction followed primary failure. In 4 cases, a covering flap was necessary. Transport used an external fixator guided by an intramedullary nail, at a rate of 1mm per day. One pin was implanted on either side of the distraction zone. The external fixator was removed 1 month after bone contact at the docking site. Mean bone transport time was 11 weeks (range: 7-15 weeks). Mean external fixation time was 5.1months (range: 3.5 to 8months). Full weight-bearing was allowed 5.7months (range: 3.5-13months) after initiation of transport. In one patient, a pin had to be repositioned. In 3 patients, the transported segment re-ascended after external fixatorablation, requiring repeat external fixation and resumption of transport. There was just 1 case of superficial pin infection. Reconstruction quality was considered "excellent" on the Paley-Marr criteria in 6 cases. The present technique provided excellent reconstruction quality in 6 of the 7 cases. External fixation time was shorter and resumption of weight-bearing earlier than with other reconstruction techniques, notably including bone autograft, vascularized bone graft or the induced membrane technique. Nailing facilitated control of limb axis and length. The complications rate was 50%, comparable to other techniques. This study raises the question of systematic internal fixation of the docking site, to avoid any mobilization of the transported segment. The bone quality, axial control and rapidity shown by the present technique make

    Given the burdens of early-onset obsessive-compulsive disorder (OCD), limitations in the broad availability and accessibility of evidence-based care for affected youth present serious public health concerns. The growing potential for technological innovations to transform care for the most traditionally remote and underserved families holds enormous promise. This article presents the rationale, key considerations, and a preliminary case series for a promising behavioral telehealth innovation in the evidence-based treatment of early-onset OCD. We developed an Internet-based format for the delivery of family-based treatment for early-onset OCD directly to families in their homes, regardless of their geographic proximity to a mental health facility. Videoteleconferencing (VTC) methods were used to deliver real-time cognitive-behavioral therapy centering on exposure and response prevention to affected families. Participants in the preliminary case series included 5 children between the ages of 4 and 8 (MAge = 6.5) who received the Internet-delivered treatment format. All youth completed a full treatment course, all showed OCD symptom improvements and global severity improvements from pre- to posttreatment, all showed at least partial diagnostic response, and 60% no longer met diagnostic criteria for OCD at posttreatment. No participants got worse, and all mothers characterized the quality of services received as “excellent.” The present work adds to a growing literature supporting the potential of VTC and related computer technology for meaningfully expanding the reach of supported treatments for OCD and lays the foundation for subsequent controlled evaluations to evaluate matters of efficacy and engagement relative to standard in-office evidence-based care.

    2015-05-01

    This study concerns a case series of 23 infants with a diagnosis of severe-to-profound hearing loss at 3 months old, who significantly improved (even reaching a normal auditory threshold) within their first year of life. All infants were routinely followed up with audiological tests every 2 months after being fitted with hearing aids as necessary. A reliable consistency between the various test findings (DPOAE, ABR, behavioral responses, CAEP and ECoG) clearly emerged in most cases during the follow-up, albeit at different times after birth. The series of infants included 7 cases of severe prematurity, 6 of cerebral or complex syndromic malformations, 5 healthy infants, 2 with asymptomatic congenital CMV infection, and 1 case each of hyperbilirubinemia, hypoxia, and sepsis. All term-born infants showed a significant improvement over their initial hearing threshold by 6 months of age, while in most of those born prematurely the first signs of threshold amelioration occurred beyond 70 weeks of gestational age, and even beyond 85 weeks in one case. Cochlear implantation (CI) should only be considered after a period of auditory stimulation and follow-up with electrophysiological and behavioral tests, and an accurate analysis of their correlation. In our opinion, CI can be performed after a period of 8 months in all term-born infants with persistent severe-to-profound hearing loss without risk of diagnostic error, whereas the follow-up for severely preterm infants should extend to at least 80 weeks of gestational age.

    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. PMID:25630329

    The aim of the study was to create a hybrid forecasting method that could produce higher accuracy forecasts than previously used 'pure' time series methods. Mentioned methods were already tested with total automotive waste, hazardous automotive waste, and total medical waste generation, but demonstrated at least a 6% error rate in different cases and efforts were made to decrease it even more. Newly developed hybrid models used a random start generation method to incorporate different time-series advantages and it helped to increase the accuracy of forecasts by 3%-4% in hazardous automotive waste and total medical waste generation cases; the new model did not increase the accuracy of total automotive waste generation forecasts. Developed models' abilities to forecast short- and mid-term forecasts were tested using prediction horizon.

  13. Effects of forefoot running on chronic exertional compartment syndrome: a case series.

    2011-12-01

    Chronic exertional compartment syndrome (CECS) is a condition that occurs almost exclusively with running whereby exercise increases intramuscular pressure compromising circulation, prohibiting muscular function, and causing pain in the lower leg. Currently, a lack of evidence exists for the effective conservative management of CECS. Altering running mechanics by adopting forefoot running as opposed to heel striking may assist in the treatment of CECS, specifically with anterior compartment symptoms. The purpose of this case series is to describe the outcomes for subjects with CECS through a systematic conservative treatment model focused on forefoot running. Subject one was a 21 y/o female with a 4 year history of CECS and subject two was a 21 y/o male, 7 months status-post two-compartment right leg fasciotomy with a return of symptoms and a new onset of symptoms on the contralateral side. Both subjects modified their running technique over a period of six weeks. Kinematic and kinetic analysis revealed increased step rate while step length, impulse, and peak vertical ground reaction forces decreased. In addition, leg intracompartmental pressures decreased from pre-training to post-training. Within 6 weeks of intervention subjects increased their running distance and speed absent of symptoms of CECS. Follow-up questionnaires were completed by the subjects at 7 months following intervention; subject one reported running distances up to 12.87 km pain-free and subject two reported running 6.44 km pain-free consistently 3 times a week. This case series describes a potentially beneficial conservative management approach to CECS in the form of forefoot running instruction. Further research in this area is warranted to further explore the benefits of adopting a forefoot running technique for CECS as well as other musculoskeletal overuse complaints.

    The objective of this proof-of-principle multicenter case series was to examine the bone regenerative potential of a newly introduced equine-derived bone mineral matrix (Equimatrix) to provide human sinus augmentation for the purpose of implant placement in the posterior maxilla. There were 10 patients requiring 12 maxillary sinus augmentations enrolled in this study. Histologic results at 6 months demonstrated abundant amounts of vital new bone in intimate contact with residual graft particles. Active bridging between residual graft particles with newly regenerated bone was routinely observed in intact core specimens. A mean value of 23.4% vital bone formation was observed at 6 months. This compared favorably with previous results using xenografts to produce bone in the maxillary sinus for the purpose of dental implant placement. Both the qualitative and quantitative results of this case series suggest comparable bone regenerative results at 6 months to bovine-derived xenografts.

    The current paper describes a case series using a new strategy for facilitating change based on Augmentation of Psychotherapy through Alternative Preconscious Priming (APAP) (1) in the treatment of eight treatment-resistant patients suffering from social phobia or generalized anxiety disorder. The patients had previously only shown a partial response to cognitive behavioral therapy (CBT) despite good treatment adherence. The patients completed APAP using a computerized program, which consisted of three steps during which alternative, more functional thoughts and beliefs relevant to the idiosyncratic difficulties experienced by the patients were formulated. Subsequently, these formulations were recorded and mixed with masking relaxing music, which the patient listened to in a passive state twice daily for 20 min for a period of 8 weeks. This case series aimed to assess the effect and acceptability of APAP using quantitative and qualitative measures administered before, after, and 16 weeks’ posttreatment. Results showed a reduction in dysfunctional idiosyncratic thoughts reported by most patients, as well as mild improvements in anxiety and important improvements in quality of life. APAP could be a valuable addition to CBT by facilitating or enhancing cognitive and symptom change. Further studies are needed to confirm these promising results. PMID:28197107

    Individuals with Huntington disease (HD), a rare neurological disease, experience impairments in mobility and cognition throughout their disease course. The Medical Research Council framework provides a schema that can be applied to the development and evaluation of complex interventions, such as those provided by physical therapists. Treatment-based classifications, based on expert consensus and available literature, are helpful in guiding physical therapy management across the stages of HD. Such classifications also contribute to the development and further evaluation of well-defined complex interventions in this highly variable and complex neurodegenerative disease. The purpose of this case series was to illustrate the use of these classifications in the management of 2 individuals with late-stage HD. Two females, 40 and 55 years of age, with late-stage HD participated in this case series. Both experienced progressive declines in ambulatory function and balance as well as falls or fear of falling. Both individuals received daily care in the home for activities of daily living. Physical therapy Treatment-Based Classifications for HD guided the interventions and outcomes. Eight weeks of in-home balance training, strength training, task-specific practice of functional activities including transfers and walking tasks, and family/carer education were provided. Both individuals demonstrated improvements that met or exceeded the established minimal detectible change values for gait speed and Timed Up and Go performance. Both also demonstrated improvements on Berg Balance Scale and Physical Performance Test performance, with 1 of the 2 individuals exceeding the established minimal detectible changes for both tests. Reductions in fall risk were evident in both cases. These cases provide proof-of-principle to support use of treatment-based classifications for physical therapy management in individuals with HD.

    This case series evaluated the use of a collagen matrix with a coronally advanced flap procedure for the treatment of multiple recession defects. Fifteen patients with a total of 80 recession defects were included. Root coverage was 85% ± 13% at 6 months and 81% ± 22% at 12 months. Complete root coverage was achieved in 60% of the sites after 6 months and in 56% after 12 months. The percentage of sites with thick gingival morphotype increased significantly. The results indicated that the collagen matrix may be a useful alternative to the connective tissue graft in the treatment of multiple recession defects.

  1. Internal and External reconnection in a Series of Homologous Solar Flares

    2000-01-01

    Using data from the Extreme Ultraviolet Telescope (EIT) on SOHO and the Soft X-ray Telescope (SXT) on Yohkoh, we examine a series of morphologically homologous solar flares occurring in NOAA AR 8210 over May 1-2, 1998. An emerging flux region (EFR) impacted against a sunspot to the west and next to a coronal hole to the east is the source of the repeated flaring. An SXT sigmoid parallels the EFR's neutral line at the site of the initial flaring in soft X-rays. In EIT, each flaring episode begins with the formation of a crinkle pattern external to the EFR. These EIT crinkles move out from, and then in toward, the EFR with velocities approximately 20 km/s. A shrinking and expansion of the width of the coronal hole coincides with the crinkle activity, and generation and evolution of a postflare loop system begins near the. time of crinkle formation. Using a schematic based on magnetograms of the region, we suggest that these observations are consistent with the standard reconnection-based model for solar eruptions, but modified by the presence of the additional magnetic fields of the sunspot and coronal hole. In the schematic, internal reconnection begins inside of the EFR-associated fields, unleashing a flare, postflare loops, and a CME. External reconnection, first occurring between the escaping CME and the coronal hole field, and second occurring between fields formed as a result of the first external reconnection, results in the EIT crinkles and changes in the coronal hole boundary. By the end of the second external reconnection, the initial setup is reinstated; thus the sequence can repeat, resulting in morphologically homologous eruptions. Our inferred magnetic topology is similar to that suggested in the "breakout model" of eruptions [Antiochos, 1998], although we cannot determine if our eruptions are released primarily by the breakout mechanism (external reconnection) or, alternatively, are released primarily by the internal reconnection.

    Induction of tolerance protocols have been applied successfully to manage allergic reactions to many medications. Hypersensitivity reactions to natalizumab (TYSABRI®) have been recognized as a growing problem. In circumstances where a hypersensitivity reaction to a medication has occurred, but no suitable alternative exists, drug induction of tolerance protocols may be considered. Drug induction of tolerance protocols were performed in three patients with prior hypersensitivity reactions to natalizumab. All three patients tolerated the protocol without adverse reactions, allowing for the safe reintroduction of natalizumab. To conclude, this case series demonstrates success with an induction of tolerance procedure to a highly effective biological agent for multiple sclerosis, in patients with allergic reactions to natalizumab.

    Myoelectric prostheses currently used by amputees can be difficult to control. Machine learning, and in particular learned predictions about user intent, could help to reduce the time and cognitive load required by amputees while operating their prosthetic device. The goal of this study was to compare two switching-based methods of controlling a myoelectric arm: non-adaptive (or conventional) control and adaptive control (involving real-time prediction learning). Case series study. We compared non-adaptive and adaptive control in two different experiments. In the first, one amputee and one non-amputee subject controlled a robotic arm to perform a simple task; in the second, three able-bodied subjects controlled a robotic arm to perform a more complex task. For both tasks, we calculated the mean time and total number of switches between robotic arm functions over three trials. Adaptive control significantly decreased the number of switches and total switching time for both tasks compared with the conventional control method. Real-time prediction learning was successfully used to improve the control interface of a myoelectric robotic arm during uninterrupted use by an amputee subject and able-bodied subjects. Adaptive control using real-time prediction learning has the potential to help decrease both the time and the cognitive load required by amputees in real-world functional situations when using myoelectric prostheses. © The International Society for Prosthetics and Orthotics 2015.

    Temporal bone fractures are relatively common findings in patients with head trauma. The aim of this study was to evaluate the characteristics of temporal bone fractures in the pediatric population. Retrospective case series. Tertiary care pediatric academic medical center. The medical records of patients aged 18 years or less diagnosed with a temporal bone fracture at the Montreal Children's Hospital from January 2000 to August 2014 were reviewed. Patient demographics, clinical presentation, mechanism of injury and complications were analyzed. Imaging studies and audiograms were also evaluated. Out of 323 patients presenting to the emergency department with a skull fracture, 61 presented with a temporal bone fracture. Of these, 5 presented with bilateral fractures. 47 patients had associated fractures, and 3 patients deceased. We observed a male to female ratio of 2.8:1, and the average age was 9.5 years. Motor vehicle accidents were the primary mechanism of injury (53%), followed by falls (21%) and bicycle or skateboard accidents (10%). The most common presenting signs included hemotympanum, decreased or loss of consciousness, facial swelling and nausea and vomiting. 8 patients had otic involvement on computed tomography scans, and 30 patients had documented hearing loss near the time of accident with a majority being conductive hearing loss. 17 patients underwent surgical management of intracranial pressure. In children, fractures of the temporal bone were most often caused by motor vehicle accidents and falls. It is common for these patients to have associated fractures.

    The 2014 report by European Medicines Agency (EMA) restricted the use of thiocolchicoside for all reproductive-age women. In this study, we aim to expand the systematically-collected human data and discuss it within the frame provided by this report. We identified and evaluated the outcomes of 48 prospectively recorded pregnancies referred to Terafar (Teratology Information Service, Izmir, Turkey). Of 42 pregnancies with first-trimester exposure and known outcomes, 31 resulted in live births, four in miscarriage and seven ended with elective terminations. There were 26 normal outcomes, two major and three minor congenital malformations among the live births. Despite a number of limitations, our results and previous case series collectively strengthen the view that thiocolchicoside is unlikely to be a major teratogen. EMA's 2014 report should be revised to reflect this finding, while current restrictions on use should continue until more detailed safety information is available. Copyright © 2018 Elsevier Inc.

    It is difficult to engage clinicians in continuing medical education that does not focus on clinical expertise. Evolving online technologies (e.g., massive open online courses [MOOCs]) are disrupting and transforming medical education, but few online nonclinical professional development resources exist. In August 2013, the Academic Life in Emergency Medicine Web site launched the Medical Education in Cases (MEdIC) series to engage clinicians in an online professional development exercise. Each month, a complex, realistic scenario featuring a nonclinical medical education dilemma is published with accompanying discussion questions. A weeklong discussion is moderated on Twitter and the Web site. This discussion is curated to create a community commentary, which is published alongside presolicited expert responses. Case resources are available for download. The first six MEdIC cases (published August 2013-January 2014) emphasized different CanMEDS and/or Accreditation Council on Graduate Medical Education competencies. Median reader engagement metrics (interquartile range 25%-75%) in the first week following publication were 861 (634-1,114) pageviews, 767 (518-953) unique visitors from 326 (218-405) cities in 45 (32-50) countries, 30 (24-39) comments, 52 (40-56) tweets, 17 (13-30) Facebook Likes, and 5 (5-7) Google Plus +1s. The MEdIC series is proof of concept that online activities can engage clinicians in nonclinical professional development. The early experience suggests the connectivist nature of MEdIC allows for crowdsourcing solutions to ill-defined problems via the wisdom of readers. This methodology may also be effective for other nonclinical and medical education topics.

    We review a consecutive case series of elders presenting to a regional psychogeriatric service in Hong Kong in 1996–2001. Eighteen elders (aged 65 and over) fulfilled the classical symptoms of Diogenes syndrome (extreme squalor, neglected physical state, unhygienic condition & social isolation with or without hoarding). A diverse clinical and socio-demographic profile was observed. Most of our clients suffered from different stages of dementia. Other diagnoses such as schizophrenia and alcohol abuse were diagnosed in this cohort as comorbid or independent conditions. Neither psychopathology nor social situations could adequately account for the initiation and perpetuation of Diogenes syndrome in some cases. The plausible psychological etiologies are discussed in the context of existential values in Chinese culture and changes in traditional family dynamics as the society modernizes. PMID:19300588

    Vitamin D is increasingly recognized to have several beneficial effects. Its toxicity, causing hypercalcemia, is considered as extremely rare. We report case series of 15 patients (most of them being elderly subjects) with iatrogenic symptomatic hypercalcemia in whom toxicity occurred due to empirical excessive administration of vitamin D by oral and parenteral route.

    To-determine the feasibility of a single paracostal abdominal approach for thoracic duct ligation (TDL) and cisterna chyli ablation (CCA) in dogs with chylothorax. Observational study and prospective case series. Normal dogs (n = 5) and dogs with chylothorax (n = 8). A single paracostal approach with transdiaphragmatic extension for TDL and CCA was developed experimentally (n = 5) and used in 8 clinical cases with subtotal pericardectomy (SPE) performed in 4 dogs. Surgery time, complications, hospitalization time, outcome, and follow-up of clinical cases were recorded. Exposure of relevant anatomy was excellent; vital lymphatic staining facilitated identification of lymphatic structures. In clinical cases, mean surgery time for TDL + CCA was 136 minutes. Mean hospitalization time was 3.1 days. Seven of 8 cases survived, with 1 dog dying of heart failure shortly after discharge. One dog required a second (left) paracostal approach to ligate 2 more lymphatic vessels. On follow-up (median, 7 months; range, 2-20 months), there was complete resolution of chylothorax in 6 dogs. A single paracostal approach provides excellent exposure of cisterna chyli, caudal thoracic duct, and intestinal lymphatics. This approach eliminates the need for repositioning during combined TDL + CCA procedures and avoids an intercostal thoracotomy. © Copyright 2011 by The American College of Veterinary Surgeons.

    OBJECTIVE: Neuroendocrine cell hyperplasia of infancy (NEHI) is a form of childhood interstitial lung disease characterized by tachypnea, retractions, crackles, and hypoxia. The aim of this study was to report and discuss the clinical, imaging, and histopathological findings in a series of NEHI cases at a tertiary pediatric hospital, with an emphasis on diagnostic criteria and clinical outcomes. METHODS: Between 2003 and 2011, 12 full-term infants were diagnosed with NEHI, based on clinical and tomographic findings. Those infants were followed for 1-91 months. Four infants were biopsied, and the histopathological specimens were stained with bombesin antibody. RESULTS: In this case series, symptoms appeared at birth in 6 infants and by 3 months of age in the remaining 6. In all of the cases, NEHI was associated with acute respiratory infection. The most common initial chest HRCT findings were ground-glass opacities that were in the middle lobe/lingula in 12 patients and in other medullary areas in 10. Air trapping was the second most common finding, being observed in 7 patients. Follow-up HRCT scans (performed in 10 patients) revealed normal results in 1 patient and improvement in 9. The biopsy findings were nonspecific, and the staining was positive for bombesin in all samples. Confirmation of NEHI was primarily based on clinical and tomographic findings. Symptoms improved during the follow-up period (mean, 41 months). A clinical cure was achieved in 4 patients. CONCLUSIONS: In this sample of patients, the diagnosis of NEHI was made on the basis of the clinical and tomographic findings, independent of the lung biopsy results. Most of the patients showed clinical improvement and persistent tomographic changes during the follow-up period, regardless of the initial severity of the disease or type of treatment. PMID:24310630

    Sebaceous gland hyperplasia is a common skin condition, very rarely reported in the female genital region. We present 13 cases from 12 patients, the first case series of sebaceous gland hyperplasia of the vulva. Differences in age at presentation and clinical presentation compared with classic sebaceous gland hyperplasia from the head and neck region were noted. Also, it was rarely included in the clinical differential diagnosis. Immunohistochemical studies to determine any possible association with the Muir-Torre syndrome were performed and mismatch repair protein loss was not identified.

    Inflammatory myoglandular polyp is an unusual but distinct, non-neoplastic type of colorectal polyp, commonly with a distal localization at the recto-sigmoidian level. It was first described in 1992 by Nakamura and his colleagues and it is considered to have few particular histological features. We report a series of seven cases (two male and five female patients) of myoglandular polyps with different localization from 15 to 40 cm from anus. Only four out of seven cases presented with rectal bleeding, the others polyps we incidentally discovered. The polyps varied between 4 and 30 mm in the maximum diameter. Grossly, they had firm consistency and smooth reddish surface. Histological examination of the specimens revealed hyperplastic glands with occasional cystic dilatation, proliferation of smooth muscle with no regular distribution, a variable amount of granulation tissue (usually minimal) and no evidence of epithelial dysplasia. All the lesions were removed endoscopically without any complications. Inflammatory myoglandular polyps are distinct histopathological entities, with insufficiently investigated pathogenesis that can include local trauma, mucosal prolapse or ischemia. Being benign they can be removed endoscopically, surgical treatment being reserved in selected cases.

    Although there is a growing body of evidence to document the safety and efficacy of operative treatment of carotid stenosis, surgical indications for elongation and kinking of the internal carotid artery remain controversial. The goal of this study was to evaluate the efficacy of surgical correction of internal carotid artery kinking in patients with persistent hemispheric symptoms despite antiplatelet therapy. A consecutive series of 81 patients (mean age, 64 years) underwent 83 surgical procedures to correct kinking of the internal carotid artery either by shortening and reimplanting the vessel on the common carotid artery, inserting a bypass graft, or transposing the vessel onto the external carotid artery. Mean follow-up was 56 months (range, 15-135 months). Study endpoints were 30-day mortality and any stroke occurring during follow-up. No postoperative death was observed. The postoperative stroke rate was 1%. Primary patency, freedom from neurologic symptoms, and late survival at 5 years (x +/- standard deviation) were 89 +/- 4.1%, 92 +/- 4%, and 71 +/- 6%, respectively. The findings of this study indicate that surgical correction for symptomatic stenotic kinking of the internal carotid artery is safe and effective in relieving symptoms and preventing stroke. Operative correction should be considered as the standard treatment for patients with symptomatic carotid kinking that does not respond to antiplatelet therapy.

    Non-infectious uveitis represents one of the most common causes of blindness, even at pediatric age; in particular, idiopathic chronic uveitis can pose significant difficulties during treatment, due to a partial response to TNF-α antagonists. To date, very few case series exist describing the treatment of idiopathic uveitis not adequately controlled by TNF-α antagonists. The aim of our study is to describe the role of abatacept in achieving remission in patients with idiopathic uveitis previously treated with TNF-α antagonists, and to assess how long abatacept efficacy is maintained during follow-up. The treatment's safety profile and tolerability were also specifically investigated. Three patients affected with chronic idiopathic uveitis, who have been treated with abatacept due to loss of efficacy of TNF-α antagonists, were reviewed. Details of the demographic and clinical characteristics were recorded, and a summary of the medical history was obtained. Patients were regularly reviewed in the ophthalmology and rheumatology clinics. Assessment of their ocular condition was characterized according to the Standardization of Uveitis Nomenclature (SUN) group. In our patients, abatacept was able to induce remission and to discontinue systemic corticosteroids after a mean of 30 weeks; the drug maintained its efficacy through a long follow-up period (42, 33, and 18 months respectively), with an excellent safety profile. Our small case series seems to suggest abatacept to be a promising therapy in children affected with chronic idiopathic uveitis not adequately controlled by TNF-α antagonists.

    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.

    The basic function of an international airport is an aerodrome, provides not only the facilities for flights management, but also for customs and passport control. Nowadays, most of the international airports have established commercial outlets for food, products and services. As such, these airports are built with larger scale and more sophisticated on both infrastructure and infostructure which aim to be the most extensive air-travel service providers that connect the nations to the international gateways. Looking at the daily operations of an international airport, the energy consumption is apprehended to be enormous. Besides, knowing the fact that reliance on fossil fuels to power the airport buildings and to run the operations daily, this has led to many negative socioenvironmental implications. To date, some of the world major international airports have begun in renewable energy adoption-which mainly focused on solar energy as a way to reduce fossil energy consumption and towards greenhouse gases reduction. Inspired by thinking differently since solar energy has been adopted in Kuala Lumpur International Airport (KLIA) in 2014, through this study we proposed another form of renewable energy-piezoelectric technology adoption into our KLIA as a feasibility study. We believe that piezoelectric technology could complement the renewable energy mix, by tapping the crowd kinetic energy gathered internally in the airport buildings particularly at a few main entrances. Hence, the objectives of this study are (a) to examine the potential factors that will foster piezoelectric tiles adoption at KLIA and (b) to propose the ways for KLIA in speeding up piezoelectric tiles adoption within the airport terminals. The case study on the Malaysia Airports Holding Berhad (MAHB which manages the KLIA) was based on primary data collected through a series of qualitative focus group conducted on 14 (8 senior managers and 6 technical professionals) who were interested and supportive

    Third ventricular cerebrospinal fluid (CSF) cysts of thalamic origin are rare. The objective of this study is to review their possible pathogenesis, clinical presentation, and management strategies with a case series describing management via an endoscopic approach with fenestration using a single burr-hole technique. A systematic literature review of reported cases of thalamic cysts was conducted with further meta-analysis of CSF cysts that involve the third ventricle. The mode of presentation, pathologic analysis, surgical management, and outcomes were analyzed. Twenty-two studies reported between 1990 and 2013 described 42 cases of thalamic cyst. Of those cases, 13 were consistent with CSF cyst that originated in the thalamus and involved the third ventricle. Eight cases (61.5%) were treated via endoscopic fenestration, 2 cases (15.4%) were surgically drained, 2 cases (15.4%) were stereotactically aspirated, and 1 case (7.69%) was observed. The most common presenting symptoms were gait disturbance (26.3%) and headaches (26.3%) followed by tremors (15.8%) and weakness (15.8%). In our series, a single burr-hole technique was a successful definitive treatment, with an average period of 23 months. Third ventricular CSF cysts of thalamic origin most commonly present with hydrocephalus. They can be safely definitively treated via endoscopic fenestration to the CSF circulation using a single burr-hole technique. Long-term follow-up shows lasting improvement in symptoms without reaccumulation of the cyst. Copyright © 2017 Elsevier Inc. All rights reserved.

    Recent evidence suggests that, for some, leaking urine may be a barrier to physical activity. Although important from a lifestyle point of view, bladder problems and incontinence also affect both men and women socially, psychologically and economically. For example, it can be particularly distressing when incontinence occurs post-prostate surgery, especially if these patients were continent before surgery. This case series outlines an aggressive, innovative, exercise-based approach to the management of stress incontinence post-prostatectomy. The program attempts to enhance neuromuscular and vascular systems associated with continence, with emphasis placed on the abdominal and pelvic floor muscles. The program was undertaken by 14 incontinent post-prostatectomy patients (mean age 63.5 y, using a mean of 3.5 sanitary pads per day). The program was initiated a mean of two months post-op and had a mean duration of six months. Upon completion of the program. 10 patients were found to be completely dry with three retaining a small leakage (a few drops). The 14th could not comply with the program because of illness. The results of this study appear promising in this patient population. There are indications for further research.

    This case series study is based on a retrospective review of medical records and case notification files of patients admitted to The Hospital das Clínicas da UNICAMP from 1985 to 2003 with a confirmed diagnosis of BSF either by fourfold rise in indirect immunofluorescence assay (IFA) titers of IgG antibodies reactive with R. rickettsii or isolation of R. rickettsii from blood or skin specimens. A median lethality of 41.9 % was observed between 1985 and 2004. The case-fatality ratio of 30 % in our study, lower than the overall São Paulo state ratio, could be explained by a higher index of suspicion and a larger experience in our hospital, a regional referral center for BSF. The presence of the classical triad of fever, rash, and headache as described in RMSF was observed in fever than half (35.2%) of our patients.

    Lewis-Sumner syndrome (LSS) is considered a variant of chronic inflammatory demyelinating polyneuropathy (CIDP), which is more frequently described with exclusive upper limb involvement. The diagnosis of LSS is clinical and electrophysiological. However, these are not always obvious and in view of its rarity, the diagnosis may be missed and patients denied effective immunomodulatory therapy. We herein describe the magnetic resonance imaging (MRI) findings in a series of five consecutive patients with a clinical diagnosis of LSS, using T2 STIR (Short Tau Inversion recovery) images without contrast. We demonstrated hyperintensity with or without hypertrophy of cervical roots and/or brachial plexus on the affected side and/or controlaterally which aided diagnostic confirmation. This helped therapeutic decision making regarding immunotherapy in all cases. MR imaging of the cervical spine/brachial plexus with T2 STIR may be helpful in suspected cases of LSS as it represents a very useful additional diagnostic tool. Copyright © 2014 Elsevier B.V.

    This document provides brief reports, or case studies, on a number of investigations sponsored by the Calibration and Validation Team (CVT) within the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Project. Chapter I describes a comparison of the irradiance immersion coefficients determined for several different marine environmental radiometers (MERs). Chapter 2 presents an analysis of how light absorption by atmospheric oxygen will influence the radiance measurements in band 7 of the SeaWiFS instrument. Chapter 3 gives the results of the second ground-based solar calibration of the instrument, which was undertaken after the sensor was modified to reduce the effects of internal stray light. (The first ground-based solar calibration of SeaWiFS is described in Volume 19 in the SeaWiFS Technical Report Series.) Chapter 4 evaluates the effects of ship shadow on subsurface irradiance and radiance measurements deployed from the deck of the R/V Weatherbird 11 in the Atlantic Ocean near Bermuda. Chapter 5 illustrates the various ways in which a single data day of SeaWiFS observations can be defined, and why the spatial definition is superior to the temporal definition for operational usage.

    Background Delayed posthypoxic leukoencephalopathy (DPHL) is a rare and underrecognized entity where patients manifest a neurological relapse after initial recovery from an acute hypoxic episode. We sought to describe the magnetic resonance imaging (MRI) findings in a group of patients with DPHL and review the available literature. Methods Retrospective case series including patients who presented with neurological and/or psychiatric symptoms after recovery from an acute hypoxic episode. The history and clinical presentation were reviewed from the electronic medical records. MRI scans were evaluated from the picture archiving and communication system. We performed a comprehensive review of the English medical literature for prior published cases of DPHL and describe the key imaging findings that have been reported related to this condition. Results A total of five patients were identified, including four patients with respiratory failure due to drug overdoses from benzodiazepines, opioids, and/or barbiturates, and one patient who presented after cardiopulmonary arrest due to pulmonary embolism. All patients showed diffuse, extensive, and confluent white matter signal abnormalities including prominent restricted diffusion, extending to the subcortical white matter and respecting the U-fibers. There was no gyral edema or contrast enhancement. In one case histopathology was available, which highlighted patchy subcortical myelin loss with sparing of U-fibers and demonstrated prominent macrophage/microglial inflammation with extensive axonal damage. Of the other four patients, two were at their neurological baselines and two had persistent neurological deficits at the time of discharge. Conclusions The described constellation of MRI findings is highly suggestive of DPHL in the appropriate clinical setting. PMID:26357591

    Peripheral neuropathy is a common cause of pain, and it is increasing in prevalence. Peripheral neuropathic pain is very hard to treat and can be resistant to multiple pain management modalities. Our series aimed at testing the efficacy of spinal cord stimulators (SCSs) in treating resistant painful peripheral neuropathy. Case 1: A 79-year-old man presented to our clinic with long-standing history of painful peripheral diabetic neuropathy resistant to conservative management. After failure of all possible modalities, we offered the patient an SCS trial that was very successful, and we proceeded with the permanent implant that continued to help with his pain and allowed the patient to wean down his medications. Case 2: A 60-year-old man presented with chronic peripheral neuropathy secondary to HIV, patient failed all conservative and procedural management. Patient then had an SCS trial that relieved his pain significantly. Unfortunately, we did not proceed with the implant due to deterioration of the patient general health. Case 3: A 39-year-old woman presented with painful peripheral neuropathy secondary to chemotherapy for breast cancer. After failure of medication management and procedures, patient had a SCS trial that improved her pain and we then proceeded with performing the permanent implant that controlled her pain. We presented 3 cases with chronic painful peripheral neuropathy secondary to HIV, diabetes mellitus, and chemotherapy that was resistant to conservative pain management and procedures that was successfully treated with neurostimulation.

    The 80-hour work-week limit for all residents was instituted in 2003 and studies looking at its effect have been mixed. Since the advent of the 16-hour mandate for postgraduate year 1 residents in July 2011, no data have been published regarding the effect of this additional work-hour restriction. To determine whether the 16-hour intern work limit, implemented in July 2011, has adversely affected operative experience. A retrospective review of categorical postgraduate year 1 Accreditation Council for Graduate Medical Education case logs from the intern class (N = 52) (with 16-hour work limit) compared with the 4 preceding years (2007-2010; N = 197) (without 16-hour work limit). A total of 249 categorical general surgery interns from 10 general surgery residency programs in the western United States were included. Total, major, first-assistant, and defined-category case totals. As compared with the preceding 4 years, the 2011-2012 interns recorded a 25.8% decrease in total operative cases (65.9 vs 88.8, P = .005), a 31.8% decrease in major cases (54.9 vs 80.5, P < .001), and a 46.3% decrease in first-assistant cases (11.1 vs 20.7, P = .008). There were statistically significant decreases in cases within the defined categories of abdomen, endocrine, head and neck, basic laparoscopy, complex laparoscopy, pediatrics, thoracic, and soft tissue/breast surgery in the 16-hour shift intern era, whereas there was no decrease in trauma, vascular, alimentary, endoscopy, liver, and pancreas cases. The 16-hour work limit for interns, implemented in July 2011, is associated with a significant decrease in categorical intern operative experience. If the 16-hour shift were to be extended to all postgraduate year levels, one can anticipate that additional years of training will be needed to maintain the same operative volume.

    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.

  10. Deformation of Cases in High Capacitance Value Wet Tantalum Capacitors under Environmental Stresses

    Teverovsky, Alexander

    2016-01-01

    Internal gas pressure in hermetic wet tantalum capacitors is created by air, electrolyte vapor, and gas generated by electrochemical reactions at the electrodes. This pressure increases substantially with temperature and time of operation due to excessive leakage currents. Deformation of the case occurs when the internal pressure exceeds pressure of the environments and can raise significantly when a part operates in space. Contrary to the cylinder case wet tantalum capacitors that have external sealing by welding and internal sealing provided by the Teflon bushing and crimping of the case, no reliable internal sealing exists in the button case capacitors. Single seal design capacitors are used for high capacitance value wet tantalum capacitors manufactured per DLA L&M drawings #04003, 04005, and 10011, and require additional analysis to assure their reliable application in space systems. In this work, leakage currents and case deformation of button case capacitors were measured during different environmental test conditions. Recommendations for derating, screening and qualification testing are given. This work is a continuation of a series of NEPP reports related to quality and reliability of wet tantalum capacitors.

    This case series describes and examines the outcomes of a remote culinary coaching program aimed at improving nutrition through home cooking. Participants (n = 4) improved attitudes about the perceived ease of home cooking (p < 0.01) and self-efficacy to perform various culinary skills (p = 0.02); and also improved in confidence to continue online learning of culinary skills and consume healthier food. We believe this program might be a viable response to the need for effective and scalable health-related culinary interventions.

    Recently, it has been reported that impairment by an 8th cervical nerve root lesion can cause drop finger, namely C8 drop finger. Here, we report a clinical case series of C8 drop finger to reveal the clinical outcome of surgical treatments to allow for a better choice of treatment. The present study included 17 consecutive patients who were diagnosed as having C8 drop finger, in which muscle strength of the extensor digitorum communis (EDC) showed a manual muscle testing (MMT) grade of 3 or less. We retrospectively investigated the clinical characteristics of C8 drop finger and recovery of muscle power was measured by subtraction of preoperative MMT of the EDC from the final follow-up values. Nine cases showed recovery of muscle power of EDC, whereas the remaining eight cases did not show any recovery including two cases of deterioration. None of the conservatively treated patients showed any recovery. Surgically treated cases included two cases of deterioration. In the cases showing recovery, recovery began 9.9 months after surgery on average and recovery took 13.8 months after surgery on average. There was a significant difference in the recovery of MMT grade between the groups treated conservatively and surgically (p = 0.049). Preoperative MMT grade of EDC showed a moderate correlation with postoperative recovery (r 2  = 0.45, p = 0.003). In other words, the severity of preoperative muscular weakness correlated negatively with postoperative recovery. C8 drop finger is better treated by surgery than conservative therapy.

    The current reference standard for unstable ankle fractures is open reduction and internal fixation using a plate and lag screws. This approach requires extensive dissection and wound complications are not uncommon. The use of intramedullary screw fixation might overcome these issues. The aim of our study was to provide an overview of the published data regarding intramedullary screw fixation of fibula fractures combined with a small consecutive case series. We performed a search of published studies to identify the studies in which fibula fractures were treated with percutaneous intramedullary screw fixation. Additionally, all consecutive patients treated for an unstable ankle fracture in a level 1 trauma center using an intramedullary screw were retrospectively included. The literature search identified 6 studies with a total of 180 patients. Wound infection was seen in 1 patient (0.6%), anatomic reduction was achieved in 168 patients (93.3%), and a loss of reduction was seen in 2 patients (1.1%). Implant removal was deemed necessary in 3 patients (1.7%) and nonunion was seen is 2 patients (1.1%). A total of 11 patients, in whom no wound complications occurred, were included in our study. The follow-up duration was a minimum of 12 months. A secondary dislocation was seen in 1 patient, and delayed union was observed after 7.5 months in 1 other patient. In conclusion, intramedullary screw fixation is a safe and adequate method to use for fibula fractures, with a low risk of wound complications. Additional research regarding functional outcome is warranted. Copyright © 2017 American College of Foot and Ankle Surgeons. Published by Elsevier Inc. All rights reserved.

    Studying the interaction between a system's components and the temporal evolution of the system are two common ways to uncover and characterize its internal workings. Recently, several maps from a time series to a network have been proposed with the intent of using network metrics to characterize time series. Although these maps demonstrate that different time series result in networks with distinct topological properties, it remains unclear how these topological properties relate to the original time series. Here, we propose a map from a time series to a network with an approximate inverse operation, making it possible to use network statistics to characterize time series and time series statistics to characterize networks. As a proof of concept, we generate an ensemble of time series ranging from periodic to random and confirm that application of the proposed map retains much of the information encoded in the original time series (or networks) after application of the map (or its inverse). Our results suggest that network analysis can be used to distinguish different dynamic regimes in time series and, perhaps more importantly, time series analysis can provide a powerful set of tools that augment the traditional network analysis toolkit to quantify networks in new and useful ways.

    2012-01-01

    This article presents the therapeutic assessment (TA; Finn, 2007) of a traumatized young woman named Claire. Claire reported feeling debilitated by academic demands and the expectations of her parents, and was finding it nearly impossible to progress in her studies. She was also finding it difficult to develop and sustain intimate relationships. The emotional aspects of close relationships were extremely difficult for her and she routinely blamed herself for her struggles in this arena. The assessor utilized the TA model for adults, with the exception of not including an optional intervention session. The steps of TA, particularly the extended inquiry and the discussion of test findings along the way, cultivated a supportive and empathic atmosphere with Claire. By employing the single-case time-series experimental design used in previous TA studies (e.g., Smith, Handler, & Nash, 2010; Smith, Wolf, Handler, & Nash, 2009), the authors demonstrated that Claire experienced statistically significant improvement correlated with the onset of TA. Results indicated that participation in TA coincided with a positive shift in the trajectory of her reported symptoms and with recognizing the affection she held for others in her life. This case illustrates the successful application of case-based time-series methodology in the evaluation of an adult TA. The potential implications for future study are discussed.

    To assess the efficacy of low-volume powder polyethylene glycol (PEG)-3350 as a sole bowel preparation for colonoscopy. This case series examined 245 consecutive patients (a mixture of inpatients and outpatients undergoing screening colonoscopy) at a hospital endoscopy center over a 2-year period. The patients received powder PEG-3350 in the amount of 204 g dissolved in 32 oz of water and taken in 3 divided doses 1 hour apart with 8 oz of water in between each dose. Colon preparation scores (CPS) were used to assess the quality of colon cleansing. The results obtained from the 245 patients were collated and compared to those of patients receiving sodium phosphate, the historical control. The mean CPS was calculated to be 3.43, with a standard deviation of 1.12. Of the 245 patients, 92 were scored with a grade of 4, and 5 patients had incomplete colonoscopies secondary to failure of bowel preparation (CPS=0). Among the remaining patients, 22 and 26 were graded as poor (CPS=1) or fair (CPS=2) bowel preparations, respectively. The low-volume powder PEG-3350 formula used in our case series showed effective colon cleansing and may be considered for use as a sole bowel preparation.

    2015-01-01

    Background Recently a preoperative pain neuroscience education (NE) program was developed for lumbar surgery (LS) for radiculopathy as a means to decrease postoperative pain and disability. This study attempts to determine the short term effects, if any, of providing NE before surgery on patient outcomes. Methods A case series of 10 patients (female = 7) received preoperative one-on-one educational session by a physical therapist on the neuroscience of pain, accompanied by an evidence-based booklet, prior to LS for radiculopathy. Post-intervention data was gathered immediately after NE, as well as 1, 3 and 6 months following LS. Primary outcome measures were Pain Catastrophization Scale (PCS), forward flexion, straight leg raise (SLR) and beliefs regarding LS. Results Immediately following NE for LS for radiculopathy, all patients had lower PCS scores, with 5 patients exceeding the MDC score of 9.1 and 8 of the patients had PCS change scores exceeding the MDC by the 1, 3 and 6 month follow ups. Physical changes showed that fingertip-to-floor test in 6 patients had changes in beyond the MDC of 4.5 cm and 6 patients had changes in SLR beyond the MDC of 5.7°. The main finding, however, indicated a positive and more realistic shift in expectations regarding pain after the impending LS by all patients. Conclusions The results of the case series suggest that immediately after NE, patients scheduled for LS for radiculopathy had meaningful detectable changes in pain catastrophizing, fingertip-to-floor test, passive SLR and positive shifts in their beliefs about LS.

    Pasteurella multocida is a well-recognized zoonotic agent following dog or cat bites or scratches. Nevertheless, prosthetic joint infection caused by P. multocida are rarely reported. We report here a series of six cases of prosthetic joint infection caused by P. multocida managed at a referral centre for the treatment of bone and joint infection in southern France. We also reviewed the 26 cases reported in literature. The mean age of our cases was 74 years [±8.2, range 63-85]. In majority of our cases (5 cases) were associated with knee prostheses and one case with a hip prosthesis. Most of cases occurred after cat or dog scratches or licks or contact. Diagnoses of prosthetic joint infection caused by P. multocida were made by positive cultures of surgical biopsies or needle aspiration. Mean time delay between prosthetic joint implantation and infection onset was 7.6 years (±5.12 years, range 2-17). Local inflammation, which occurred in all six cases, was the most frequent clinical symptom, followed by pain in five cases, fever and swollen joints in four cases, and a fistula with purulent discharge inside the wound in two cases. The mean time of antibiotic therapy was 8 months. Surgical treatment with prosthesis removal was performed in three cases. Six of our cases were in remission without apparent relapse at 3 years after end of treatment. Prosthetic joint infections caused by P. multocida usually occur after animal scratches or bites, but can occasionally occur after a short animal lick. These infections are usually resulting from a contiguous infection and localized in the knee. An early antibiotic therapy after surgical debridement could avoid prosthetic withdrawal, notably in elderly patients. Patients with prosthetic joints should be warned that animals are potential sources of serious infection and urgent medical advice should be sought if they are bitten or scratched.

    1999-03-01

    In breast reconstruction with free TRAM flaps, the thoracodorsal vessels are most commonly used as recipient vessels. In case of an irradiated and scarred axillary region, the internal thoracic vessels may be an alternative. In the pertinent literature it has been pointed out that the veins may be fragile and thin and, thus, not suitable for microvascular anastomosis. In a series of 31 breast reconstructions with free TRAM flaps, the internal thoracic vessels were dissected and evaluated in 24 cases in order to assess the value of this vascular system as a recipient site for free flap transplantation. In four cases, the veins were too small for anastomosis, and in one case the artery was severed during dissection. End-to-end anastomoses were performed in 19 cases (79%). The following complications were recorded: One marginal necrosis; one venous thrombosis, which was detected and salvaged by revision; one recurrent arterial thrombosis, resulting in flap loss; one pleural lesion healed uneventfully.

    Objectives To review the presentation, treatment and response of those runners from the London Marathon who presented to St Thomas' Hospital with exercise induced hyponatraemia. Design Observational case series. Setting St Thomas' Hospital, a tertiary hospital situated near the finish line of the 2003 London Marathon. Participants All runners who presented to St Thomas' Hospital on the day of the 2003 London Marathon with altered mental state whose serum sodium concentration was less than 135 mmol/L. Main outcome measures Presenting symptoms, volume and type of fluids administered and response to treatment (biochemical and clinical). Results Fourteen patients were diagnosed with exercise associated hyponatraemia with serum sodium concentrations ranging from 116 to 133 mmol/L. Eleven presented with confusion. There were long delays between the finish time and presentation time for some runners. Anecdotal descriptions suggested some runners finished the race with normal mental state then became confused. There was no correlation between running time and serum sodium level. All patients received 0.9% saline and six received 1.8% saline. Despite this, some patients demonstrated falls in serum sodium concentrations. Thirteen to fourteen patients were symptomatically well the following morning, with the remaining patient significantly improved. Conclusion Presentation of exercise associated hyponatraemia may be delayed. Optimal treatment is controversial, but the use of isotonic saline may not result in rises of serum sodium and we would suggest the early use of hypertonic fluids in symptomatic patients.

    Although the shoulder is known to move together with the scapula and other upper quarter joints, the current frozen shoulder clinical practice guidelines describe only physical therapy study treatments directed to the shoulder. None received a strong recommendation, highlighting the need for alternate interventions. This retrospective case series describes a pragmatic regional interdependence approach to frozen shoulder with impairment and functional outcomes, noting whether final ROM approached normal. Five consecutive patients referred with frozen shoulder diagnoses attended 11-21 sessions over 5-10 weeks with one physical therapist. Treatment addressed inter-related regions (shoulder, shoulder girdle, scapulothoracic/humerothoracic, and spine) following a pragmatic approach using impairment-based interventions (joint/soft tissue mobilization, muscle stretching/strengthening) as well as patient education, modalities and warm up that addressed individual presentations. All patients improved on all outcomes. Mean shoulder ROM at discharge, the impairment outcome, demonstrated large effect size increases: flexion (117 ± 10-179 ± 12, d  = 5.9), abduction (74 ± 8-175 ± 9, d  = 9.3), external rotation (23 ± 7-89 ± 2, d  = 12.0). The Disability of Arm Shoulder Hand functional outcome score upon follow up demonstrated a large effect size improvement ( d  = 1.5) from 40.0 ± 19.4-6.2 ± 3.7. Final ROM approached normal. This case series utilized a regional interdependence approach to frozen shoulder that included manual therapy interventions directed to consistent upper quarter body segments. Shoulder ROM was returned to near normal with functional improvements evident months after discharge. A pragmatic regional interdependence approach addressing multiple joints related to shoulder function may benefit other people with frozen shoulder. 4.

    This case-series describes the 6 human infections with Onchocerca lupi, a parasite known to infect cats and dogs, that have been identified in the United States since 2013. Unlike cases reported outside the country, the American patients have not had subconjunctival nodules but have manifested more invasive disease (eg, spinal, orbital, and subdermal nodules). Diagnosis remains challenging in the absence of a serologic test. Treatment should be guided by what is done for Onchocerca volvulus as there are no data for O. lupi. Available evidence suggests that there may be transmission in southwestern United States, but the risk of transmission to humans is not known. Research is needed to better define the burden of disease in the United States and develop appropriately-targeted prevention strategies. PMID:26611778

    2015-01-01

    Objective Social Security beneficiaries’ liberty is constrained if they are judged incapable of managing their disability payments and are assigned a fiduciary to manage benefit payments on their behalf. Conversely, beneficiaries’ well-being may be compromised if they misspend money that they need to survive. Several studies have shown that determinations of financial capability are made inconsistently and capability guidelines appear to be applied inconsistently in practice. This case series describes the ambiguities remaining for a small number of individuals even after published criteria for capability— failing to meet basic needs and/or harmful spending on drugs— are applied. Methods Trained, experienced assessors rated the financial capability of 119 individuals in intensive outpatient or inpatient psychiatric facilities who received SSI or SSDI payments. Ten individuals’ cases were determined difficult to judge. Results Six sources of ambiguity were identified by case review: distinguishing incapability from the challenges of navigating poverty, the amount of nonessential spending needed to be considered incapable, the amount of spending on harmful things needed to be considered incapable, how intermittent periods of capability and incapability should be considered, the relative weighting of past behavior and future plans to change, and discrepancies between different sources of information. Conclusion The cases raise fundamental questions about what financial incapability is, but also illustrate how detailed consideration of beneficiaries’ living situations and decision making can inform the difficult dichotomous decision about capability.

    Contemporary approaches to the treatment of cerebral palsy (CP) advocate a task-specific approach that emphasizes repetition and practice of specific tasks. Recent studies suggest that body-weight-supported treadmill training (BWSTT) programs may be beneficial in clinical settings. The purposes of this case series were to explore the outcomes and feasibility of a home-based BWSTT program for three children with CP. Three children with CP at Gross Motor Function Classification System (GMFCS) Levels III or IV participated in this case series. Examination included the Functional Assessment Questionnaire (FAQ), the 10-meter walk test, the Gross Motor Function Measure (GMFM-66), and the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT). A harness system was used to conduct the BWSTT program over an 8-12 week period. All of the families reported enjoying the BWSTT program and found the harness easy to use. Participant 2 increased from a 2 to a 4 on the FAQ, while Participant 3 increased from a 6 to a 7. Two of the participants demonstrated post-intervention improvements in functional mobility. In addition to mobility outcomes, future research should explore the potential health benefits of a home-based BWSTT program.

    Stridor in paediatric age group is not an uncommon presentation to the ENT emergency. The range of differential diagnosis is vast. The presentation may vary from noisy breathing to severe respiratory distress and apnea. Early and meticulous diagnosis is crucial for the management as the condition may be life threatening. We report a rare case series of 3 infants with Arnold Chiari Malformation who presented to the hospital with stridor and were diagnosed with bilateral vocal cord palsy. These 3 infants had similar underlying neurological condition with hydrocephalus and raised intracranial pressure. Chiari malformation is the one of the most common congenital central nervous system anomaly associated with bilateral vocal cord paralysis. However, the presentation is rare. This article, thus, emphasizes the significance of early diagnosis and immediate management of this condition. PMID:27790480

    To describe the use of a re-entry catheter in the endovascular treatment of left subclavian stenosis. We present three patients where initial attempts at re-vascularisation using standard techniques were unsuccessful. An OUTBACK catheter was employed to facilitate re-entry in these patients. True lumen re-entry was achieved in all patients, leading to successful treatment of all stenoses. There was a lack of filling of the left vertebral artery post-angioplasty in one patient; this was not clinically significant. The case series presented is encouraging for the use of a re-entry catheter in the treatment of subclavian occlusion. In our limited experience this has proved to be a safe technique for use in patients who fail re-vascularisation by standard methods; a larger study is required to confirm this.

    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.

    2009-01-01

    Purpose: To report a case series of conjunctival lymphangiectasia treated with liquid nitrogen cryotherapy. Methods: A 1.5-mm Brymill cryoprobe was applied in a double freeze-thaw method after an incisional biopsy of a portion of the conjunctiva in patients with conjunctival lymphangiectasia. Freeze times were 1 to 2 seconds with thawing of 5 to 10 seconds between treatments. Patients were reexamined at 1 day, 2 weeks, 3 months, 6 months, and yearly following cryotherapy. Results: Five eyes of 4 patients (3 male and 1 female) with biopsy-proven conjunctival lymphangiectasia underwent liquid nitrogen cryotherapy. The average patient age was 53 years. Ocular examination revealed large lymphatic vessels that were translucent and without conjunctival injection. Subjective symptoms included epiphora, ocular irritation, eye redness, and occasional blurred vision. After treatment with liquid nitrogen cryotherapy, the patients’ symptoms and signs resolved within 2 weeks. Lymphangiectasia recurred twice in one patient, at 1 and 3 years postoperatively. In another patient, lymphangiectasia recurred at 6 months. The average time to recurrence in these 3 eyes was 18 months. Average length of follow-up was 24.5 months for all subjects. Conclusion: Liquid nitrogen cryotherapy may be an effective surgical alternative in the treatment of conjunctival lymphangiectasia. Cryotherapy may need to be repeated in some instances.

    2011-04-27

    We report a long-term series of nine workers suffering from vibration-induced neuropathy, after many years of exposure to hand-held vibrating tools at high or low frequency. They were treated with temporary selective cutaneous anaesthesia (EMLA® cream) of the forearm repeatedly for a period up to one year (in two cases four years). The aim was to improve their capacity to perceive touch and thereby improve hand function and diminish disability. The treatment principle is based on current concepts of brain plasticity, where a deafferentation of a skin area results in improved sensory function in adjacent skin areas. All participants had sensory hand problems in terms of numbness (median touch thresholds > 70 mg) and impaired hand function influencing ADL (mean DASH score 22).After an initial identical self-administered treatment period of 8 weeks (12-15 treatments with increasing intervals) they did one treatment every 2-3 month. After one year sensibility (touch thresholds and tactile discrimination) as well as hand function (mean DASH score 13) were improved in a majority of the cases. Seven of the participants choose to continue the treatment after the first year and two of them have continued at a regular basis for up to four years. A surprising, secondary finding was diminishing nocturnal numbness of the hand and arm in eight of the nine subjects from "frequently" to "hardly ever or never". Our observations open new perspectives for treatment of impaired sensibility and hand function in a group of patients with vibration induced hand problems where we have no treatment to offer today.

    The Zika virus (ZIKV) is an emerging arthropod-borne virus related to the dengue virus (DENV), and shows a similar clinical profile as other arboviral diseases, such as dengue and chikungunya virus (CHIKV). Historically, ZIKV has been associated with sporadic cases of human infection, but is now responsible for outbreaks worldwide. In Brazil, cases have been reported since 2015, with some cases causing severe disease. To identify clinical symptoms of Zika in patients in Dengue suspected patients. Description of a series of cases, wherein we analyzed 100 clinical samples collected from patients who exhibited acute febrile disease for ≤5days, from January to February 2016. In this study, we report 13 cases of ZIKV infection in adults presenting dengue-like symptoms in a DENV endemic area. All patients presented with fever, with myalgia being the second most frequently observed symptom. Two patients had rashes, but none of them had conjunctivitis. Other less frequent manifestations included headache, arthralgia, diarrhea, and nausea. The co-circulation of ZIKV and DENV is a serious public health concern, since it represents both a clinical and diagnostic challenge in endemic areas, as well as in the field of travel medicine.

    Necrotising fasciitis (NF) is a severe infection of deep subcutaneous soft tissues with high morbidity and mortality. Periocular necrotising fasciitis (PONF) is a very rare condition with many unanswered questions about the presentation and management. We present a retrospective case series of patients with PONF from three centres in Australia and two in the UK to investigate the clinical and microbiological characteristics and outcomes and report on patients treated with antibiotics alone. Twenty-nine patients (20 men; 69%) with PONF were identified and followed up for between 2 months and 10 years (median 57, mean 52.6 months) between 1990 and 2013. Conditions associated with chronic immunocompromise were present in 16/29 (55%). Twenty-one (75%) recalled minor periocular trauma or an infected lesion, two having been assaulted by the same assailant. Systemic shock occurred in 6/29 (21%) patients and 1 died. Group A, β-haemolytic Streptococcus was the most common bacterium identified (25/29, 86%). Intravenous antibiotics were used in all patients, and up to five tissue debridements were required to control the disease in 23/29 (74%); reconstructive surgery was required in 12/29 (41%) patients. One patient died from the disease and visual loss occurred in four eyes of four patients (14%). PONF has a better prognosis than disease elsewhere in the body, but is still associated with significant risk of visual loss and a small risk of death. Intravenous antibiotic treatment with cautious observation may be reasonable in selected patients with a low threshold for debridement. Published by the BMJ Publishing Group Limited.

    In recent years, a new technology for autologous epidermal harvesting has been developed to produce epidermal skin grafts (ESGs) for use over wounds. This technology employs negative pressure and heat to raise the epidermal skin layer, allowing for consistent and reproducible epidermal harvesting. The aim of this case series is to present the authors' experience using an automated, epidermal harvesting system to produce ESGs to treat wounds of patients with multiple comorbidities. This case series was conducted between January 1, 2013 and December 31, 2014. Patients with wounds (≤ 25 cm2) that failed to heal were treated with ESGs by a group of 3 wound care physicians in 2 outpatient wound care centers in a community health center setting. A total of 94 patients with 102 wounds were identified. Of the 94 patients, 3 were noncompliant and 9 were lost to follow-up. Therefore, 82 patients with 90 wounds were included in the analysis. The majority of wounds demonstrated epithelialization (83/90, 92.2%). Of the 90 wounds, 75 (83.3%) healed following epidermal grafting, 4 (4.4%) wounds displayed improvement, and 11 (12.2%) did not heal. Minimal or no pain at the donor site was reported by the patients, and all donor sites healed without complications. This case series provides additional evidence for the use of ESGs for the treatment of wounds that fail to heal.

    Current recommendations for the anesthetic management of placenta accreta support a conservative approach with neuraxial anesthesia and uterine artery embolization. These are based on case series from experienced centers in developed countries. The aim of this study was to describe the anesthetic management of placenta accreta in a low-resource setting. A retrospective case note review was performed. From 1 August 2006 to 31 July 2011 placentas from cases of suspected placenta accreta were reassessed histologically to confirm the diagnosis. Patient charts were reviewed and information on anesthetic technique, monitoring, blood transfusion, maternal and fetal outcomes was extracted. Thirty-nine cases were identified. Mean (± SD) maternal age was 33 ± 5.4 years. Hysterectomy was performed at the time of cesarean section in all cases. Thirty-four patients received neuraxial anesthesia, of whom 15 required conversion to general anesthesia. Invasive blood pressure monitoring was used in all patients and a central venous catheter was inserted in 33 cases. Complications associated with monitoring occurred in five patients. Median [IQR] blood loss was 2000 [1100-2700] mL and the median [IQR] number of units of red blood cell transfused was 2 [0-6]. Vasoactive medication was used in 14 patients and 15 patients were transferred to the intensive care unit postoperatively. No maternal or newborn deaths occurred. A multidisciplinary approach can prove valuable when placenta accreta is suspected before delivery. In low-resource settings, lack of interventional radiology services and prenatal diagnostic capability may have an impact on anesthetic management in patients with placenta accreta. However, other than greater blood loss, our study demonstrated that good maternal and neonatal outcomes are possible in spite of limited resources. Copyright © 2015 Elsevier Ltd.

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). 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. 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 < 0.0001]. A non-significant increase in overall mortality risk was found among dialysed animals relative to those managed with conservative treatment, independent of animal type and the etiology of their AKI. The pooled proportions for overall mortality according to etiology, regardless of treatment type, were: AKI due infectious etiology for cats and 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]. 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.

    Sino-nasal cancer (SNC) are rare tumours with an elevated occupational etiological fraction, due both to well-established risk factors (wood and leather) and to more rare carcinogens. We evaluated the assessment for workers' compensation performed by the Italian Authority (INAL) in a case-series of occupational SNC (N = 45). We observed an elevated proportion of cases that were recognised as occupational, overall (36 on 39) and for any histotype. INAIL tended to recognize as professional not only patients with exposure to wood and leather but also cases with a documented exposure to formaldehyde, metal, polycyclic hydrocarbons. Significant differences across Italian macro-regions appeared, when the amount of worker compensation was investigated.

    Patients who have undergone unicompartmental knee arthroplasty (UKA) have been reported to exhibit altered gait 19-25 months post-surgery. The most common gait impairment in this population is inadequate knee flexion and a corresponding decrease in the knee extensor moment during loading response (i.e., quadriceps avoidance). The purpose of this case series was to determine whether incorporation of antigravity treadmill training into a standard physical therapy program can eliminate quadriceps avoidance gait during the early rehabilitation phase following UKA. Four females who underwent UKA were recruited for this study. Participants completed antigravity treadmill training three times per week for 12 weeks in addition to their standard physical therapy program. Instrumented gait analysis was performed at baseline (pre-intervention), week 6 (mid-intervention), and week 12 (post-intervention). We found that peak knee flexion and the peak knee extensor moment during the weight acceptance phase of gait increased to normal values following the 12-week intervention period (14.1 ± 6.5° to 20.6 ± 1.5° and 0.4 ± 0.3 to 0.7 ± 0.2 Nm/kg respectively). The findings of this case series suggest that a standard physical therapy program that incorporates early gait training using an antigravity treadmill may be beneficial in eliminating "quadriceps avoidance" during the early rehabilitation phase following UKA.

    Minimally invasive techniques are becoming increasingly popular in thoracic surgery. Although median sternotomy is the traditional approach for thymectomy, video-assisted thoracoscopic surgery (VATS) approaches now predominate. This study reports a case series of the novel uniportal subxiphoid-VATS approach to extended thymectomy. Over the period of study (October 2014-January 2017) 17 patients underwent uniportal subxiphoid-VATS extended thymectomy for a thymic nodule at the Shanghai Pulmonary Centre. Ten patients were female, and the mean age of the cohort was 55 years. The mean size of nodule was 23.6 mm. The mean operative duration was 2.5 hours, with one conversion to thoracotomy for bleeding. The mean operative blood loss was 115 mL. The median length of hospital stay was 4 days. There were no episodes of phrenic nerve palsies. The 30-day survival was 100%. Uniportal subxiphoid-VATS is a feasible and safe surgical approach to extended thymectomy in selected patients, with good post-operative outcomes.

    The prevalence of hMPV infections in Sri Lanka has not been reported and here we report a case series of hMPV infection in children less than 5 years. Patients with ARTI were included from Teaching Hospital, Anuradhapura from March 2013 to August 2014. Indirect fluorescence assay was performed on nasopharyngeal aspirates for the identification of respiratory viruses [respiratory syncytial virus (RSV), parainfluenza virus 1, 2 and 3, influenza A and B and hMPV]. Moreover, reverse transcriptase-polymerase chain reaction was done to further confirm the hMPV infection. In this case series, hMPV infection showed a range of respiratory symptoms from common cold to life threatening lower respiratory tract infections with varying severity. In some cases, the clinical presentation of hMPV infection was similar to the ARTI caused by RSV. hMPV co-infections with of RSV have also been seen in some cases of ARTI. A child delivered through cesarean section and birth order > 3 has an Odds ratio of 3.5 and 4.3 (95% CI) for developing co-infection with RSV compared to hMPV mono-infections. Lack of diagnostic facilities to identify the viral aetiology has contributed to the use of antibiotics indicating the need for establishing viral diagnostic facilities in the country.

Seven children with arthrogryposis and a diagnosis of congenital infection presumably caused by Zika virus during the Brazilian microcephaly epidemic. Main clinical, radiological, and electromyographic findings, and likely correlation between clinical and primary neurological abnormalities. The brain images of all seven children were characteristic of congenital infection and arthrogryposis. Two children tested positive for IgM to Zika virus in the cerebrospinal fluid. Arthrogryposis was present in the arms and legs of six children (86%) and the legs of one child (14%). Hip radiographs showed bilateral dislocation in seven children, subluxation of the knee associated with genu valgus in three children (43%), which was bilateral in two (29%). All the children underwent high definition ultrasonography of the joints, and there was no evidence of abnormalities. Moderate signs of remodeling of the motor units and a reduced recruitment pattern were found on needle electromyography (monopolar). Five of the children underwent brain computed tomography (CT) and magnetic resonance imaging (MRI) and the remaining two CT only. All presented malformations of cortical development, calcifications predominantly in the cortex and subcortical white matter (especially in the junction between the cortex and white matter), reduction in brain volume, ventriculomegaly, and hypoplasia of the brainstem and cerebellum. MRI of the spine in four children showed apparent thinning of the cord and reduced ventral roots. Congenital Zika syndrome should be added to the differential diagnosis of congenital infections and arthrogryposis. The arthrogryposis was unrelated to the abnormalities

    32 consecutive total gastrectomies for cancer (20 extended total gastrectomies) were carried out through an abdominal approach. Reconstruction using a Rouxen-Y loop (28 cases) or an interposed jejunal loop (four cases) was done with an EEA stapled oesophago jejunostomy: 25 end to side and 5 end to end anastomosis were performed and two technical failures led to complete manual anastomosis. All patients have had post-operative X-ray examination: there was no anastomotic leakage in this series, even in the 3 patients (10%) who have died during the post-operative course. A critical study of this series and eight others one from elsewhere is presented: it is concluded that the stapling device allows an easier and safer oesophagojejunostomy than manual procedure, when great care is taken of technical details.

    Gorlin-Goltz syndrome (GGS) seems to be unusual in black persons. The authors present an Afro-Brazilian family case report of GGS. The main complaint of the index case was a painless swelling of the left mandible, which was diagnosed as an odontogenic keratocyst. Further classical features of the Syndrome were present in this patient. Other two family members were diagnosed as cases of GGS and one of them presented 11 clinical findings characteristic of the syndrome. From the three cases reported, two of them presented five major diagnostic criteria for the GGS, and the diagnosis was only made because of an oral complaint. This case series emphasizes the importance of carefully examining the patient and close relatives for signs of GGS, even if they belong to an ethnic group in which this diagnosis is unusual. © 2014 Special Care Dentistry Association and Wiley Periodicals, Inc.

    We present a case series of snow crab-induced occupational asthma (OA) from a fishing and processing vessel, followed by a review of OA in the commercial fishing industry. OA is typically caused from an IgE-mediated hypersensitivity reaction after respiratory exposure to aerosolized fish and shellfish proteins. It more commonly occurs due to crustaceans, but molluscs and fin fish are implicated as well. Standard medical therapy for asthma may be used acutely; however, steps to reduce atmospheric allergen concentrations in the workplace have proven to be preventive for this disease.

    Infective endocarditis is associated with not only cardiac complications but also neurologic, renal, musculoskeletal, and systemic complications related to the infection, such as embolization, metastatic infection, and mycotic aneurysm. We report three cases (the first patient is Chinese and the other two are Koreans) of complicated infective endocarditis; two of the cases were associated with a mycotic aneurysm, and one case was associated with a splenic abscess. One case of a patient with prosthetic valve endocarditis was complicated by intracerebral hemorrhage caused by mycotic aneurysm rupture. A second case of a patient with right-sided valve endocarditis associated with a central catheter was complicated by an abdominal aortic mycotic aneurysm. The third patient had a splenic infarction and abscess associated with infected cardiac thrombi. Complicated infective endocarditis is rare and is associated with cardiac, neurologic, renal, musculoskeletal, and systemic complications related to infection, such as embolization, metastatic infection, and mycotic aneurysm. Infective endocarditis caused by Staphylococcus aureus is more frequently associated with complications. Because the mortality rate increases when complications develop, aggressive antibiotic therapy and surgery, combined with specific treatments for the complications, are necessary.

  17. Clustering Financial Time Series by Network Community Analysis

    NASA Astrophysics Data System (ADS)

    Piccardi, Carlo; Calatroni, Lisa; Bertoni, Fabio

    In this paper, we describe a method for clustering financial time series which is based on community analysis, a recently developed approach for partitioning the nodes of a network (graph). A network with N nodes is associated to the set of N time series. The weight of the link (i, j), which quantifies the similarity between the two corresponding time series, is defined according to a metric based on symbolic time series analysis, which has recently proved effective in the context of financial time series. Then, searching for network communities allows one to identify groups of nodes (and then time series) with strong similarity. A quantitative assessment of the significance of the obtained partition is also provided. The method is applied to two distinct case-studies concerning the US and Italy Stock Exchange, respectively. In the US case, the stability of the partitions over time is also thoroughly investigated. The results favorably compare with those obtained with the standard tools typically used for clustering financial time series, such as the minimal spanning tree and the hierarchical tree.

This raises concerns regarding hermeticity of the single seal parts and their capability to withstand high internal gas pressures that might develop during operation in space. To address these issues, T22 series capacitors rated to 50 V and 125 V were subjected to highly accelerated life testing (HALT) at 125 C and rated voltage and step stress random vibration testing (RVT). To simulate conditions of storage or operation under increased internal gas pressure, the parts were stored at temperature of 150 C for 2500 hr (HTS150). Electrical characteristics of the parts were measured through the storage testing and the hermeticity leak rate was tested before and after HTS150. To assess thermo-mechanical robustness of the part, capacitors were manually soldered onto printed wired boards (PWB) and stressed by 1000 temperature cycles between -55 C and +125 C. The effect of temperature cycling was assessed by additional HALT at different temperatures. Results show that T22 series capacitors have robust design and can satisfy requirements for space applications.

    Myasthenia gravis is an autoimmune neuromuscular disease, usually affecting women in the second and third decades. The course is unpredictable during pregnancy and puerperium. Myasthenia gravis can cause major interference in labour and partum and exacerbations of the disease frequently occur. The aim of this series of cases is to analyse retrospectively the anaesthetic management of myasthenia gravis patients and complications during the peripartum period. Retrospective, single centre study from clinical files of female myasthenia gravis patients who delivered between 1985 and 2007 at Hospital de Santo António, Porto, Portugal. Seventeen myasthenia gravis patients delivered between 1985 and 2007 in Hospital Santo António. Two women were not included in the study as they had a spontaneous abortion in the first trimester. Four patients presented exacerbations of the disease during pregnancy, no exacerbation occurred in eight patients and three patients presented their first symptoms of myasthenia gravis during pregnancy (without diagnosis at time of delivery). Concerning the eight patients without exacerbations of the disease during pregnancy, pregnancy was brought to term in 87.5% of the cases; five women were submitted to nonurgent caesarean section (62.5%); and epidural block was performed in six patients (75%). No complications related to anaesthesia occurred in the peripartum period. Concerning the four patients with exacerbations of the disease, pregnancy was brought to term in three cases (75%); three women were submitted to nonurgent caesarean section (75%); and epidural block was performed in three patients (75%). One patient underwent an uncomplicated thymectomy under general anaesthesia during pregnancy and, in the postpartum period, there was a myasthenic crisis in another patient. Concerning the three patients without a myasthenia gravis diagnosis at partum, one woman already being followed for presenting muscular weakness had a vaginal delivery under

    2013-05-01

    This paper addresses the topic of classifying financial time series in a fuzzy framework proposing two fuzzy clustering models both based on GARCH models. In general clustering of financial time series, due to their peculiar features, needs the definition of suitable distance measures. At this aim, the first fuzzy clustering model exploits the autoregressive representation of GARCH models and employs, in the framework of a partitioning around medoids algorithm, the classical autoregressive metric. The second fuzzy clustering model, also based on partitioning around medoids algorithm, uses the Caiado distance, a Mahalanobis-like distance, based on estimated GARCH parameters and covariances that takes into account the information about the volatility structure of time series. In order to illustrate the merits of the proposed fuzzy approaches an application to the problem of classifying 29 time series of Euro exchange rates against international currencies is presented and discussed, also comparing the fuzzy models with their crisp version.

    Traumatic injury to the popliteal vascular zone remains a challenging problem on the modern battlefield and is frequently associated with more complications than other vascular injuries. Limb salvage and morbidity (graft infection, thrombosis and delayed haemorrhage) were studied. All popliteal vascular injuries over an 8 month period admitted to the Military Base Hospital were analyzed. Local limb evaluation included confirmation of the presence of ischaemia, extent of soft tissue damage, muscle viability after calf fasciotomy, and neurological injury. Ischaemic time was recorded from the time of injury to definitive revascularization. If there was a prior attempt at reconstruction, the amputation was considered delayed. For a series of 44 patients with popliteal vascular injury average time to presentation was 390min, 46% were completely ischaemic. Of those 39 (89%) had popliteal artery injuries. There were 24 (62%) complete popliteal artery transections and associated venous (69%) and osseous (46%) injuries. The preferred technique of repair was inter-position venous graft (IPVG) (54%). Eleven immediate amputations were performed (28%). There were 13 wound infections (33%), 5 early graft thromboses (5 of 21 IPVG, 238%), 2 anastomotic disruptions (2 of 21 IPVG, 9%), which resulted in 4 delayed amputations. Mortality was 5% (2 patients). In this case series of popliteal artery injury early identification of limbs at risk, early four compartment fasciotomy, temporary intra-luminal shunting, definitive repair of concomitant venous injuries and aggressive treatment of haemodynamic instability were shown to be beneficial in achieving reasonable outcome in an austere environment with limited recourses.

    Most patients with pulmonary atelectasis have complete resolution with medical therapy. In patients with persistent atelectasis, endoscopic treatment has proven to be an effective therapy. To describe our experience using flexible fiberoptic bronchoscopy in children with persistent atelectasis. This is a case series report of children treated with flexible bronchoscopy between January 2005 and December 2013, at the Pediatric Pulmonology Section of the Hospital Italiano de Buenos Aires. From a total of 106 bronchoscopies performed, 32 of the patients had a diagnosis of persistent atelectasis. Mean age, 5 years. Laryngeal mask airway was the most common route for flexible bronchoscopy. In 28/32 patients, the procedure was therapeutically useful (complete or partial re-expansion). The procedure was well tolerated and presented only mild complications. Flexible bronchoscopy proved to be a safe and effective tool for the treatment of children with persistent atelectasis.

    2015-01-01

    Laparoscopic bariatric surgery requires retraction of the left lobe of the liver to provide adequate operative view and working space. Conventional approaches utilize a mechanical retractor and require additional incision(s), and at times an assistant. This study evaluated the safety and efficacy of a suture-based method of liver retraction in a large series of patients undergoing laparoscopic bariatric surgery. This method eliminates the need for a subxiphoid incision for mechanical retraction of the liver. Two hospitals in the Midwest with a high volume of laparoscopic bariatric cases. Retrospective chart review identified all patients undergoing bariatric surgery for whom suture-based liver retraction was selected. The left lobe of the liver is lifted, and sutures are placed across the right crus of the diaphragm and were either anchored on the abdominal wall or intraperitoneally to provide static retraction of the left lobe of the liver. In all, 487 cases were identified. Patients had a high rate of morbid obesity (83% with body mass index >40 kg/m(2)) and diabetes (34.3%). The most common bariatric procedures were Roux-en-Y gastric banding (39%) and sleeve gastrectomy (24.6%). Overall, 6 injuries to the liver were noted, only 2 of which were related to the suture-based retraction technique. Both injuries involved minor bleeding and were successfully managed during the procedure. The mean number of incisions required was 4.6. Suture-based liver retraction was found to be safe and effective in this large case series of morbidly obese patients. The rate of complications involving the technique was extremely low (.4%).

    INTRODUCTION Inflammatory pseudotumor (IPT) is a rare lesion consisted of inflammatory and myofibroblastic cells. These lesions may be found in different organs. There are less than 300 described cases. PRESENTATION OF CASE Case 1. 64-year-old cirrhotic male with a palpable epigastric mass. CT showed a lesion in liver segments 2 and 3 and left hepatic artery aneurism. Percutaneous embolization and wide spectrum antibiotics were tried, however the lesion grew. Left lateral hepatectomy was performed, and HIPT diagnosed. The patient died due to multiple organ dysfunction. Case 2. 30-year-old male with abdominal pain and fever. CT showed a hepatic hilar lesion. Surgical resection was performed after an ineffectual antibiotic trial, and HIPT was confirmed. The patient is doing well. Case 3. 73-year-old female with abdominal pain and fever. CT showed a 7 cm lesion in the left liver lobe. Unrewarding cancerous screening was performed, and unsuccessful antibiotic course was tried. Resection was performed, and HIPT diagnosed. The patient is doing well. Case 4. 50-year-old cirrhotic male with abdominal pain. CT showed a segment 6 lesion and portal vein thrombosis. Considering cancer as the first hypothesis and the MELD score of 9, segmentectomy was performed. HIPT was the final diagnosis. The patient died due to abdominal sepsis. DISCUSSION HIPT is a lesion with a vast list of differential diagnosis. Antibiotics are the first line of therapy, although surgery is often necessary. Overall prognosis is good, although comorbidities may worsen it. CONCLUSION HIPT is a rare and misleading entity. PMID:23399515

    Sovereign citizens hold a variety of beliefs that challenge the legitimacy of the United States government and criminal justice system. In criminal cases, sovereign citizens typically raise a variety of seemingly strange objections to the proceedings that can cause court participants to believe the defendant is not competent to stand trial. The author's case files were reviewed to identify all defendants who espoused sovereign citizen beliefs during a court-ordered competence-to-stand-trial evaluation. This case series consisted of nine evaluations completed between 2003 and 2012. A review of the outcomes in these cases showed that sovereign citizens typically have the capacity to understand criminal proceedings and assist an attorney. © 2014 American Academy of Psychiatry and the Law.

    Extrarenal pseudoaneurysms of transplanted kidneys are very rare but can have devastating consequences. In the past, these extrarenal pseudoaneurysms have often led to graft loss as well as significant morbidity and mortality. The role of advanced diagnostic imaging studies and of modern radiologic interventional management has not been studied. In this case series, we present four cases of extrarenal pseudoaneurysms of transplanted kidneys, describe the clinical scenarios and imaging that led to the angiographic diagnosis, and discuss the various endovascular and surgical approaches to management.

    To provide an insight into the presentation, diagnosis and management of paediatric abdominal tuberculosis (TB) in developed countries. The records of all children at the Montreal Children's Hospital (MCH) admitted with abdominal TB between 1990 and 2014 were reviewed. An automated and manual literature search from 1946 to 2014 was performed. (1) CASE SERIES: six cases were identified at the MCH. All were male between 5 and 17 years of age. All were from populations known to have high rates of TB (aboriginal, immigrant). Three underwent major surgical interventions and three underwent ultrasound (US) or CT aspiration or biopsy for diagnosis. (2) LITERATURE REVIEW: 29 male (64%) and 16 female subjects (36%) aged between 14 months and 18 years were identified, including the MCH patients. All patients except one were from populations with a high incidence of TB. Most presented with a positive tuberculin skin test (90%), abdominal pain (76%), fever (71%) and weight loss (68%). On imaging, 22 (49%) were classified with gastrointestinal TB with colonic wall irregularity (41%) and 19 (42%) with peritoneal TB with ascites (68%). A positive culture was obtained in 33 (73%) patients. Three cases used CT- or US-guided aspiration or biopsy to obtain tissue samples. A surgical intervention was performed in 34 (76%) children; 13 (38%) of these were for diagnosis. Diagnosis based on clinical features (abdominal pain, fever and weight loss) and CT- or US-guided aspiration or biopsy may encourage physicians to adopt a more conservative approach to abdominal TB.

    Chlorpromazine is a low potency "typical" antipsychotic agent used to treat schizophrenia. It continues to be prescribed frequently in India owing to its lower cost. There have been previous reports of ocular adverse effects with prolonged use of chlorpromazine. We report three patients who developed corneal and lenticular opacities secondary to prolonged chlorpromazine use leading to visual impairment. Early detection of ocular deposits and switching over to risperidone from chlorpromazine helped in the reversal of chlorpromazine- induced ocular side effects in one of them. The case series further adds evidence to the causative relationship between chlorpromazine and ocular side effects. Copyright © 2016 Elsevier B.V. All rights reserved.

  10. Modeling Non-Gaussian Time Series with Nonparametric Bayesian Model.

    PubMed

    Xu, Zhiguang; MacEachern, Steven; Xu, Xinyi

    2015-02-01

    We present a class of Bayesian copula models whose major components are the marginal (limiting) distribution of a stationary time series and the internal dynamics of the series. We argue that these are the two features with which an analyst is typically most familiar, and hence that these are natural components with which to work. For the marginal distribution, we use a nonparametric Bayesian prior distribution along with a cdf-inverse cdf transformation to obtain large support. For the internal dynamics, we rely on the traditionally successful techniques of normal-theory time series. Coupling the two components gives us a family of (Gaussian) copula transformed autoregressive models. The models provide coherent adjustments of time scales and are compatible with many extensions, including changes in volatility of the series. We describe basic properties of the models, show their ability to recover non-Gaussian marginal distributions, and use a GARCH modification of the basic model to analyze stock index return series. The models are found to provide better fit and improved short-range and long-range predictions than Gaussian competitors. The models are extensible to a large variety of fields, including continuous time models, spatial models, models for multiple series, models driven by external covariate streams, and non-stationary models.

    2017-06-01

    The purpose of this case series was to describe the short-term and long-term clinical effects of a manual technique for treating osteoarthritis (OA) knee pain. This study measured of the immediate effect and long-term effect by using a case series of different groups of subjects. Knee OA and activity restriction in patients were evaluated by using the Kellgren-Lawrence (K/L) Grading Scale and the Japanese Knee Osteoarthritis Measure (JKOM) index. In the intervention, lower limb muscles were squeezed by hand for 20 seconds. Each squeeze was performed for both lower limbs. Passive range-of-motion (ROM) exercise was performed on the knee joint. In one set of cases, immediate effects were measured after a one-time treatment with pretreatment and posttreatment outcome measures. Eleven people with knee OA participated in the study. On a visual analogue scale (VAS) for pain, muscle stiffness, and muscular hemodynamics for estimation of muscle blood flow were recorded before and after the squeeze-hold treatment. In another set of cases, the treatment was given to all patients once a week for 6 months, and long-term effects were measured. Data on 5 subjects with knee OA were collected for 6 months after initial treatment. The VAS for pain and JKOM were recorded every month for 6 months. For immediate effects, the VAS was 69 ± 21 mm before treatment and 26 ± 22 mm after treatment. Muscle stiffness was 8.8 ± 3.6 (absolute number) before treatment and 3.5 ± 2.1 after treatment. Tissue (muscle) oxygen saturation was 60.1 ± 5.7% before treatment and 65.3 ± 4.8% after treatment. Total hemoglobin was 24.3 ± 3.3 (absolute number) before treatment and 25 ± 2.3 after treatment. A tendency for reduction in OA knee pain and muscle stiffness was observed, and a tendency for increase was observed in the blood flow in the muscle. For long-term effects in all 5 participants (any K/L grade, any JKOM score), OA knee pain and JKOM score improved gradually through 6 months. The

    Introduction This study is a prospective case series analyzing the effects of a comprehensive lifestyle intervention program in three patients with chronic paraplegia having major risks for the cardiometabolic syndrome (CMS). Case presentation: Individuals underwent an intense 6-month program of circuit resistance exercise, nutrition using a Mediterranean diet and behavioral support, followed by a 6-month extension (maintenance) phase involving minimal support. The primary goal was a 7% reduction of body mass. Other outcomes analyzed insulin resistance using the HOMA-IR model, and plasma levels of fasting triglycerides and high-density lipoprotein cholesterol. All participants achieved the goal for 7% reduction of body mass and maintained the loss after the MP. Improvements were observed in 2/3 subjects for HOMA-IR and high-density lipoprotein cholesterol. All participants improved their risk for plasma triglycerides. Discussion: We conclude, in a three-person case series of persons with chronic paraplegia, a lifestyle intervention program involving circuit resistance training, a calorie-restrictive Mediterranean-style diet and behavioral support, results in clinically significant loss of body mass and effectively reduced component risks for CMS and diabetes. These results were for the most part maintained after a 6-month MP involving minimal supervision. PMID:28382218

    There is mixed evidence that older people bereaved of a spouse or partner are at risk of adverse outcomes. The main difficulty is to take account of other explanatory factors. We tested for an association between a patient's death and the timing of any bereavement of a cohabitee. Self-controlled case series study in which each case serves as his or her own control and which thereby accounts for all fixed measurable and unmeasurable confounders. We used the Health Improvement Network (THIN) primary care database to identify patients who died aged 50-99 years during the period 2003 to 2014. We used the household identifier in the database to determine whether they had an opposite sex cohabitee at the start of the observation period. 38,773 men and 23,396 women who had died and who had a cohabitee at the start of the observation period, were identified and included in male and female cohorts respectively. A higher risk of death was found in the 24 months after the death of the cohabitee than in the time classified as unexposed. The greatest risk was during the first 3 months after the death of the cohabitee (age-adjusted incidence rate ratio [IRR] 1.63, 95% CI 1.45-1.83 in the male cohort, and IRR 1.70, 95% CI 1.52-1.90 in the female cohort). Risk of death in men or women was significantly higher after the death of a cohabitee and this was greatest in the first three months of bereavement. We need more evidence on the effectiveness of interventions to reduce this increased mortality.

  14. Improving hand sensibility in vibration induced neuropathy: A case-series

    PubMed Central

    2011-01-01

    Objectives We report a long-term series of nine workers suffering from vibration-induced neuropathy, after many years of exposure to hand-held vibrating tools at high or low frequency. They were treated with temporary selective cutaneous anaesthesia (EMLA® cream) of the forearm repeatedly for a period up to one year (in two cases four years). The aim was to improve their capacity to perceive touch and thereby improve hand function and diminish disability. The treatment principle is based on current concepts of brain plasticity, where a deafferentation of a skin area results in improved sensory function in adjacent skin areas. Methods All participants had sensory hand problems in terms of numbness (median touch thresholds > 70 mg) and impaired hand function influencing ADL (mean DASH score 22). After an initial identical self-administered treatment period of 8 weeks (12-15 treatments with increasing intervals) they did one treatment every 2-3 month. Results After one year sensibility (touch thresholds and tactile discrimination) as well as hand function (mean DASH score 13) were improved in a majority of the cases. Seven of the participants choose to continue the treatment after the first year and two of them have continued at a regular basis for up to four years. A surprising, secondary finding was diminishing nocturnal numbness of the hand and arm in eight of the nine subjects from "frequently" to "hardly ever or never". Conclusions Our observations open new perspectives for treatment of impaired sensibility and hand function in a group of patients with vibration induced hand problems where we have no treatment to offer today.

    Congenital shunts of the portal venous system are rare entities that can present in children with clinical heterogeneity. To evaluate the clinical course of children with uncommon shunts presenting to our institution and examine the available literature on this topic. Medical records of children with rare forms of congenital shunts were retrospectively reviewed for demographics, symptoms, management, and outcome between 2003 and 2016. Three female patients with congenital shunts, including a congenital mesenterico-portal Rex shunt (n = 1) and congenital portosystemic shunts (CPSS) (n = 2), were referred for surgical evaluation between ages 4 and 9. Median follow-up was 8 years (range, 6-13 years). One asymptomatic patient did not require treatment and remained disease-free during long-term follow-up. The other 2 patients with CPSS and unusual symptoms, including liver focal nodular hyperplasia (FNH) in infancy (n = 1) and bleeding from esophageal varices (n = 1), showed subsequent progression to liver nodules that were managed by endovascular shunt occlusion. One patient showed symptom resolution and the other showed stable lesions at last follow-up. Literature yielded descriptions of two cases of congenital mesenterico-portal Rex shunt, one case of coincident CPSS and FNH in infancy, but zero reports of bleeding from esophageal varices. This case series examines each distinct patient's presentation, discusses the diagnosis, management and outcome and compares findings while discussing literature on this topic. A high index of suspicion and familiarity with unusual forms and treatment options is required to allow timely diagnosis and appropriate treatment.

    2014-09-01

    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.

    2017-05-01

    Status migrainosus (SM) is defined as a severe migraine attack, usually poorly responsive to treatments, lasting more than 72 h. Recurrent SM predicts chronic migraine (CM) development in 83.7% of cases. There is evidence that in most unresponsive CM patients a sinus stenosis-associated raised intracranial pressure is causatively involved in migraine chronification. To test the hypothesis that SM may reflect a sustained rise in intracranial pressure, we tested the efficacy of a 3-day treatment with intravenous mannitol 18% 250 ml b.i.d. in seven subjects presenting with a SM unresponsive to common treatments, showing unilateral or bilateral sinus stenosis at magnetic resonance venography. Mannitol infusion induced the abrupt reduction or the disappearance of pain in all patients, at least along the 3 days of treatment. While the benefit was only observed during the days of treatment in two subjects, in the remaining five patients the time to the next headache was delayed between 20 days to 5 weeks after mannitol infusion. Due to the lack of any analgesic property of mannitol, our data indicate that in this series a rise in intracranial pressure was involved in SM causative mechanisms.

    Preterm, critically ill neonates represent a challenge in wound healing. Many factors predispose infants to skin injuries, including decreased epidermal-dermal cohesion, deficient stratum corneum, relatively alkaline pH of skin surface, impaired nutrition and presence of multiple devices on the skin. We present a case series describing the use of medical-grade honey-Leptospermum honey (Medihoney), for successful treatment of slowly healing neonatal wounds, specifically stage 3 pressure ulcer, dehiscent and infected sternal wound, and full-thickness wound from an extravasation injury.

    2010-01-01

    According to the DSM-IV, Mental Retardation is significantly sub-average general intellectual functioning accompanied by significant limitations in adaptive functioning in at least two of the following skill areas: communication, self-care, home living, social/interpersonal skills, use of community resources, self-direction, functional academic skills, work, leisure, health and safety. In pilot work, we have seen positive clinical effects of Neurofeedback (NF) applied to children with Trisomy 21 (Down Syndrome) and other forms of mental retardation. Given that many clinicians use NF in Attention Deficit Hyperactivity Disorder and Generalized Learning Disability cases, we studied the outcomes of a clinical case series using Quantitative EEG (QEEG) guided NF in the treatment of mental retardation. All 23 subjects received NF training. The QEEG data for most subjects had increased theta, alpha, and coherence abnormalities. A few showed increased delta over the cortex. Some of the subjects were very poor in reading and some had illegible handwriting, and most subjects had academic failures, impulsive behavior, and very poor attention, concentration, memory problems, and social skills.
