A case report is a narrative that describes, for medical, scientific, or educational purposes, a medical problem experienced by one or more patients. Case reports written without guidance from reporting standards are insufficiently rigorous to guide clinical practice or to inform clinical study design. Develop, disseminate, and implement systematic reporting guidelines for case reports. We used a three-phase consensus process consisting of (1) pre-meeting literature review and interviews to generate items for the reporting guidelines, (2) a face-to-face consensus meeting to draft the reporting guidelines, and (3) post-meeting feedback, review, and pilot testing, followed by finalization of the case report guidelines. This consensus process involved 27 participants and resulted in a 13-item checklist-a reporting guideline for case reports. The primary items of the checklist are title, key words, abstract, introduction, patient information, clinical findings, timeline, diagnostic assessment, therapeutic interventions, follow-up and outcomes, discussion, patient perspective, and informed consent. We believe the implementation of the CARE (CAse REport) guidelines by medical journals will improve the completeness and transparency of published case reports and that the systematic aggregation of information from case reports will inform clinical study design, provide early signals of effectiveness and harms, and improve healthcare delivery.

Controversy exists about residual symptoms after pharmacological treatment of Lyme neuroborreliosis. Reports of disabling long-term sequels lead to concerns in patients and health care providers. We systematically reviewed the available evidence from studies reporting treatment of Lyme neuroborreliosis to assess the prevalence and spectrum of residual symptoms after treatment. A literature search was performed in three databases and three clinical trial registers to find eligible studies reporting on residual symptoms in patients after pharmacological treatment of LNB. Diagnosis must have been performed according to consensus-derived case definitions. No restrictions regarding study design or language were set. Symptom prevalence was pooled using a random-effects model. Forty-four eligible clinical trials and studies were found: 8 RCTs, 17 cohort studies, 2 case-control studies, and 17 case series. The follow-up period in the eligible studies ranged from 7 days to 20 years. The weighted mean proportion of residual symptoms was 28 % (95 % CI 23-34 %, n = 34 studies) for the latest reported time point. Prevalence of residual symptoms was statistically significantly higher in studies using the "possible" case definition (p = 0.0048). Cranial neuropathy, pain, paresis, cognitive disturbances, headache, and fatigue were statistically significantly lower in studies using the "probable/definite" case definition. LNB patients may experience residual symptoms after treatment with a prevalence of approximately 28 %. The prevalence and spectrum of residual symptoms differ according to the applied case definition. Symptoms like fatigue are not reported in studies using the "probable/definite" case definition. As the "possible" case definition is more unspecific, patients with other conditions may be included. Reports of debilitating fatigue and cognitive impairment after LNB, a "post-Lyme syndrome", could therefore be an artifact of unspecific case definitions in single studies.

Randomized clinical trial (RCT) can fail to demonstrate the richness of individual patient characteristics. Given the unpredictable nature of medicine, a patient may present in an unusual way, have a strange new pathology, or react to a medical intervention in a manner not seen before. The publication of these novelties as case reports is a fundamental way of conveying medical knowledge. Throughout history there have been famous case studies that shaped the way we view health and disease. Case reports can have the following functions: (I) descriptions of new diseases; (II) study of mechanisms; (III) discovery new therapies; (IV) recognition of side effects; and (V) education. Before submitting a case report, it is worthwhile to refer to the Case Report Check Sheet described by Green and Johnson [2006].

Police Officer Schema of Sexual Assault Reports: Real Rape, Ambiguous Cases, and False Reports.

PubMed

Venema, Rachel M

2016-03-01

While extensive research has studied sexual assault reporting behaviors and described negative experiences with the criminal justice system among victim-survivors, fewer studies have explored police officer attitudes, knowledge, and thought processes that may affect victims' perceptions of negative interactions and unsatisfactory outcomes within reported sexual assault cases. This study explores police officer understanding of the definition of sexual assault and characteristics that influence their perceptions and response. Ten police officers were interviewed within one police department in a midsized city in the Great Lakes region. The study uses a modified grounded theory approach. Findings suggest that officers employ distinct schema of reported sexual assaults. Case characteristics, perceived credibility of the victim, and types of evidence formed categorizations of false reports, ambiguous cases, and legitimate sexual assaults. Police officers describe the ways in which perceptions of the case may or may not influence the response and point to areas for improvement within police procedure. The study findings provide insight into recommendations for improved police interviewing and response to reported sexual assaults. © The Author(s) 2014.

2014-01-01

The case-cohort study design combines the advantages of a cohort study with the efficiency of a nested case-control study. However, unlike more standard observational study designs, there are currently no guidelines for reporting results from case-cohort studies. Our aim was to review recent practice in reporting these studies, and develop recommendations for the future. By searching papers published in 24 major medical and epidemiological journals between January 2010 and March 2013 using PubMed, Scopus and Web of Knowledge, we identified 32 papers reporting case-cohort studies. The median subcohort sampling fraction was 4.1% (interquartile range 3.7% to 9.1%). The papers varied in their approaches to describing the numbers of individuals in the original cohort and the subcohort, presenting descriptive data, and in the level of detail provided about the statistical methods used, so it was not always possible to be sure that appropriate analyses had been conducted. Based on the findings of our review, we make recommendations about reporting of the study design, subcohort definition, numbers of participants, descriptive information and statistical methods, which could be used alongside existing STROBE guidelines for reporting observational studies.

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.

Delineation of an endemic tick paralysis zone in southeastern Australia.

Whitfield, Zoe; Kelman, Mark; Ward, Michael P

2017-11-30

Tick paralysis has a major impact on pet dog and cat populations in southeastern Australia. It results from envenomation by Ixodes holocyclus and Ixodes cornuatus ticks, the role of Ixodes cornuatus in the epidemiology of this disease in Australia being unclear. The aim of this study was to describe the geographical distribution of tick paralysis cases in southeastern Australia using data from a national disease surveillance system and to compare characteristics of "endemic" cases with those reported outside this endemic zone ("sporadic" cases). Data were collated and a proportional symbol map of all cases by postcode was created. A 15-case isopleth was developed based on descriptive spatial statistics (directional ellipses) and then kernel smoothing to distinguish endemic from sporadic cases. During the study period (January 2010-December 2015) 12,421 cases were reported, and 10,839 of these reported by clinics located in 434 postcodes were included in the study. Endemic cases were predominantly reported from postcodes in coastal southeastern Australia, from southern Queensland to eastern Victoria. Of those cases meeting selection criteria, within the endemic zone 10,767 cases were reported from 351 (88%) postcodes and outside this zone 72 cases were reported from 48 (12%) postcodes. Of these latter 48 postcodes, 18 were in Victoria (26 cases), 16 in New South Wales (28 cases), 7 in Tasmania (9 cases), 5 in South Australia (7 cases) and 2 in Queensland (2 cases). Seasonal distribution in reporting was found: 62% of endemic and 52% of sporadic cases were reported in spring. The number of both endemic and sporadic cases reported peaked in October and November, but importantly a secondary peak in reporting of sporadic cases in April was found. In non-endemic areas, summer was the lowest risk season whilst in endemic areas, autumn was the lowest risk season. Two clusters of sporadic cases were identified, one in South Australia (P=0.022) during the period 22 May to 2 June 2012 and another in New South Wales (P=0.059) during the period 9 October to 29 November 2012. Endemic and sporadic cases did not differ with respect to neuter status (P=0.188), sex (P=0.205), case outcome (P=0.367) or method of diagnosis (P=0.413). However, sporadic cases were 4.2-times more likely to be dogs than cats (P<0.001). The endemic tick paralysis zone described is consistent with previous anecdotal reports. Sporadic cases reported outside this zone might be due to a history of pet travel to endemic areas, small foci of I. holocyclus outside of the endemic zone, or in the case of southern areas, tick paralysis caused by I. cornuatus.

Exploring the interpersonal-, organization-, and system-level factors that influence the implementation and use of an innovation-synoptic reporting-in cancer care.

2012-03-01

The dominant method of reporting findings from diagnostic and surgical procedures is the narrative report. In cancer care, this report inconsistently provides the information required to understand the cancer and make informed patient care decisions. Another method of reporting, the synoptic report, captures specific data items in a structured manner and contains only items critical for patient care. Research demonstrates that synoptic reports vastly improve the quality of reporting. However, synoptic reporting represents a complex innovation in cancer care, with implementation and use requiring fundamental shifts in physician behaviour and practice, and support from the organization and larger system. The objective of this study is to examine the key interpersonal, organizational, and system-level factors that influence the implementation and use of synoptic reporting in cancer care. This study involves three initiatives in Nova Scotia, Canada, that have implemented synoptic reporting within their departments/programs. Case study methodology will be used to study these initiatives (the cases) in-depth, explore which factors were barriers or facilitators of implementation and use, examine relationships amongst factors, and uncover which factors appear to be similar and distinct across cases. The cases were selected as they converge and differ with respect to factors that are likely to influence the implementation and use of an innovation in practice. Data will be collected through in-depth interviews, document analysis, observation of training sessions, and examination/use of the synoptic reporting tools. An audit will be performed to determine/quantify use. Analysis will involve production of a case record/history for each case, in-depth analysis of each case, and cross-case analysis, where findings will be compared and contrasted across cases to develop theoretically informed, generalisable knowledge that can be applied to other settings/contexts. Ethical approval was granted for this study. This study will contribute to our knowledge base on the multi-level factors, and the relationships amongst factors in specific contexts, that influence implementation and use of innovations such as synoptic reporting in healthcare. Such knowledge is critical to improving our understanding of implementation processes in clinical settings, and to helping researchers, clinicians, and managers/administrators develop and implement ways to more effectively integrate innovations into routine clinical care.

Pathology analysis for mesothelioma study in the United Kingdom: Current practice and historical development.

Case, B W

2016-01-01

Following up on the largest case-control study of malignant mesothelioma yet performed, investigators at the London School of Hygiene and Tropical Medicine assessed 1732 male and 670 female cases as of May 2013. Epidemiological findings of a subset of these were published previously, excluding patients who died or who refused to be interviewed. Pathology reports were collected for subjects, including those both eligible and ineligible for epidemiology study based on vital status. The current investigation examined 860 cases having pathology reports available. Sixty-one cases were diagnosed using cytology only, often with equivocal diagnoses, while 799 reported at least a biopsy of the tumor. Of these, 748 had pathology sufficiently detailed for evaluation. These reports were examined for basis of diagnosis, differences between study cases and ineligible cases, pathology characteristics, and immunohistochemical and other tests used. The most prominent subtype was epithelioid (64% of study cases but only 49% of ineligible cases). Biphasic subtype was present in 10% of study cases and 16% of those ineligible. Sarcomatoid subtype was present in 7% of study cases and 19% of ineligible cases, most of whom died. Twelve percent of study cases displayed no specified subtype, versus 7% of ineligible cases. Of recorded immunohistochemical stains specific for mesothelial cell origin, calretinin (95%) and CK 5/6 or CK5 alone (84%) were by far the most common. Calretinin and CK 5/6 or CK 5 alone were also most sensitive and positive in 92% of cases presenting with surgical pathology report. Ninety percent of cases had at least one immunohistochemical marker for possible lung carcinoma applied, with BER-Ep4 and TTF-1 the most frequent at 68% and CEA at 58%. TTF-1 and CEA were positive in 1% or less of cases. Patterns of use and positive and negative results for each of these as well as other immunohistochemical stains are presented and discussed, along with a brief historical description of their development and use. Possible effects of the pathologic analysis on the results of previously published and future epidemiological studies are discussed.

Although an estimated three million tuberculosis (TB) cases worldwide are missed by national TB programs annually, the level of under-reporting of diagnosed cases in high TB burden settings is largely unknown. To quantify and describe under-reporting of sputum smear-positive TB cases in Kenya. A national-level retrospective TB inventory study was conducted. All sputum smear-positive TB cases diagnosed by public or private laboratories during 1 April-30 June 2013 were extracted from laboratory registers in 73 randomly sampled subcounties and matched to TB cases in the national TB surveillance system (TIBU). Bivariate and multivariate analyses were conducted. In the subcounties sampled, 715 of 3409 smear-positive TB cases in laboratory registers were not found in TIBU. The estimated level of under-reporting of smear-positive TB cases in Kenya was 20.7% (95%CI 18.4-23.0). Under-reporting was greatest in subcounties with a high TB burden. Unreported cases were more likely to be patients aged ⩾55 years, have scanty smear results, and be diagnosed at large facilities, private facilities, and facilities in high TB burden regions. In Kenya, one fifth of smear-positive TB cases diagnosed during the study period went unreported, suggesting that the true TB burden is higher than reported. TB surveillance in Kenya should be strengthened to ensure all diagnosed TB cases are reported.

We conducted the first pilot Italian study to assess the preventability of adverse drug reactions involving psychotropic drugs reported through spontaneous reporting system from 01/07/2012 to 31/12/2014 in Campania Region. Preventability was assessed, case-by-case, using an adapted version of the P-method. The evaluation was performed only for those reports that had, as suspected drug, antipsychotics, mood stabilizers, antidepressants, anxiolytic and/or sedative-hypnotic. Eighty-one cases (19.2%) out of 421 reported during the study period were preventable. In seventy-seven (95.1%) out of 81 preventable cases, the underlying mechanism of the adverse drug reactions was dose-related, in four (4.9%) preventable cases the underlying mechanism of the adverse drug reactions was respectively susceptibility- (1; 1.2%), unknown- (1; 1.2%) and time-related (2; 2.5%). In the 81 preventable cases, 97 critical criteria were detected of which 29/97 (29.9%) related to healthcare professionals' practices, 0/97 (0.0%) to drug quality and 68/97 (70.1%) to patient behaviour. We proved that it was possible to apply and adapt the P-Method to assess the preventability of the adverse drug reactions involving psychotropic drugs, analysing individual case safety report sent through Campania Region spontaneous reporting system. Information acquired will be used to organize educational activities for both physicians and patients to promote a more appropriate drug use.

In the United Kingdom, pertussis guidance recommends prophylaxis for household contacts within 21 days of case symptom onset if the household includes a vulnerable contact. The aim of our study was to identify characteristics associated with cases reported late for public health action. We reviewed the epidemiology of cases reported in London and South East England for the period 2010 to 2015. We characterised risk factors associated with late reporting of cases and described public health actions taken on timely reported cases. From 2010 to 2015, 9,163 cases of pertussis were reported to health protection teams. Only 11% of cases were reported within 21 days of onset, limiting opportunities for secondary prevention. Timely reporting was associated with younger age groups, pregnancy, being a healthcare worker and being reported by schools or hospital clinicians. Late reporting was associated with older age groups and general practitioner or laboratory reporting. Delays, such as those due to insidious onset and late presentation to healthcare, may be unavoidable; however, delay in reporting once a patient presents can be reduced since cases can be reported before laboratory confirmation. Thus we recommend working with clinicians and laboratories to determine causes and improve early reporting to public health. PMID:28749334

Developing the DESCARTE Model: The Design of Case Study Research in Health Care.

PubMed

Carolan, Clare M; Forbat, Liz; Smith, Annetta

2016-04-01

Case study is a long-established research tradition which predates the recent surge in mixed-methods research. Although a myriad of nuanced definitions of case study exist, seminal case study authors agree that the use of multiple data sources typify this research approach. The expansive case study literature demonstrates a lack of clarity and guidance in designing and reporting this approach to research. Informed by two reviews of the current health care literature, we posit that methodological description in case studies principally focuses on description of case study typology, which impedes the construction of methodologically clear and rigorous case studies. We draw from the case study and mixed-methods literature to develop the DESCARTE model as an innovative approach to the design, conduct, and reporting of case studies in health care. We examine how case study fits within the overall enterprise of qualitatively driven mixed-methods research, and the potential strengths of the model are considered. © The Author(s) 2015.

To identify errors in forensic reports and to describe the characteristics of traumatic medico-legal cases presenting to the emergency department (ED) at a tertiary care hospital. This study is a retrospective cross-sectional study. The study includes cases resulting in a forensic report among all traumatic patients presenting to the ED of Adiyaman University Training and Research Hospital, Adiyaman, Turkey during a 1-year period. We recorded the demographic characteristics of all the cases, time of presentation to the ED, traumatic characteristics of medico-legal cases, forms of suicide attempt, suspected poisonous substance exposure, the result of follow-up and the type of forensic report. A total of 4300 traumatic medico-legal cases were included in the study and 72% of these cases were male. Traumatic medico-legal cases occurred at the greatest frequency in July (10.1%) and 28.9% of all cases occurred in summer. The most frequent causes of traumatic medico-legal cases in the ED were traffic accidents (43.4%), violent crime (30.5%), and suicide attempt (7.2%). The most common method of attempted suicide was drug intake (86.4%). 12.3% of traumatic medico-legal cases were hospitalized and 24.2% of those hospitalized were admitted to the orthopedics service. The most common error in forensic reports was the incomplete recording of the patient's "cooperation" status (82.7%). Additionally, external traumatic lesions were not defined in 62.4% of forensic reports. The majority of traumatic medico-legal cases were male age 18-44 years, the most common source of trauma was traffic accidents and in the summer months. When writing a forensic report, emergency physicians made mistakes in noting physical examination findings and identifying external traumatic lesions. Physicians should make sure that the traumatic medico-legal patients they treat have adequate documentation for reference during legal proceedings. The legal duties and responsibilities of physicians should be emphasized with in-service training.

Anti-tumour necrosis factor (TNF) agents, through their intense immunoregulatory effect, have been suspected to increase the risk of malignant lymphoma. However, the classical epidemiological approaches conducted over about the last 10 years have not totally succeeded in addressing the question of a causal or artifactual association. Therefore, the analysis of a substantial set of case reports, although usually considered as poorly generalizable to the general population, could be particularly informative. Two main sources of case reports in postmarketing settings are available; publications in medical journals and reports to pharmacovigilance systems. The aim of the study was to compare the characteristics of case reports from both these sources in order to understand whether they provided the same information for the investigation of the causal link between lymphoma and anti-TNF agents. All case reports of malignant lymphoma in patients treated with an anti-TNF agent published in MEDLINE and all reports to the French pharmacovigilance system up to 1 February 2010 were identified. Cases of malignant lymphoma identified in postmarketing surveillance from both sources were compared regarding the following variables: age, sex, anti-TNF agent involved, indication for use, type of lymphoma, prior or concomitant immunosuppressive drugs and time to onset of lymphoma. A total of 81 published case reports and 61 cases reported to the French pharmacovigilance system were compared. In published reports, patients were younger (p = 0.03) and more frequently receiving a first anti-TNF treatment (p = 0.03), particularly infliximab (p = 0.03). Conversely, in the pharmacovigilance system reports, a succession of different anti-TNFs (p = 0.03) and adalimumab (p < 0.0001) were more frequently reported. Lymphomas in patients treated with anti-TNF agents for Crohn's disease were more prevalent in published cases than in pharmacovigilance reports (p < 0.0001), and in particular involved hepatosplenic T-cell lymphoma. Conversely, rheumatoid arthritis was the main indication for anti-TNF agents in pharmacovigilance reports (p = 0.01). Time to onset was markedly shorter in published cases (median 12 months) than in pharmacovigilance reports (median 30 months; p = 0.0001). Characteristics of published cases and those reported to the French pharmacovigilance system differed markedly for all characteristics tested, except sex and the use of prior or concomitant immunosuppressive drugs. Published case reports favoured convincing arguments for drug causation whereas cases reported to the pharmacovigilance system were more disparate but could describe more accurately the reality of lymphoma occurrence in this particular population. These results argue for the use of the pharmacovigilance reports when case reports are used to investigate the causal link between lymphoma and anti-TNF agents at the population level. Data from cases notified to the French pharmacovigilance system did not indicate an increased risk of lymphoma during the early phase of anti-TNF treatment. To confirm this hypothesis, a study combining pharmacovigilance reports from several countries, or, if feasible, a cohort study both with a large sample size and a long duration of follow-up would be required.

The case-control design in veterinary sciences: A survey.

The case-control study design is deceptively simple. However, many design considerations influence the estimated effect measure. An investigation of case-control studies in the human health literature suggested that some of these considerations are not described in reports of case-control studies. Our hypothesis was that the majority of veterinary studies labeled as case-controls would be incident density designs, and many would not interpret the effect measure obtained from those studies as the rate ratio rather than the odds ratio. Reference databases were searched for author-designated case-control studies. A survey of 100 randomly selected studies was conducted to examine the different design options described and estimated effect measures. Of the 100 author-identified case-control studies, 83 assessed an exposure-outcome association and, of those, only 54 (65.1%) sampled the study population based on an outcome and would thus be considered case-control designs. Twelve studies were incidence density designs but none used this terminology. Of the studies that reported an odds ratio as the effect measure, none reported on additional considerations that would have enabled a more interpretable result. This survey indicated many case-control-labeled studies were not case-control designs and among case-control studies, key design aspects were not often described. The absence of information about study design elements and underlying assumptions in case-control studies limits the ability to establish the effect measured by the study and the evidentiary value of the study might be underestimated.

Background: Malaria elimination requires infection detection using quality assured diagnostics and appropriate treatment regimens. Although Botswana is moving towards malaria elimination, reports of unconfirmed cases may jeopardise this effort. This study aimed to determine the proportion of cases treated for malaria that were confirmed by rapid diagnostic testing (RDT) and/or microscopy. Methods: This was a retrospective descriptive study using routine national data from the integrated disease surveillance and case-based surveillance systems from 2008 to 2014. The data were categorised into clinical and confirmed cases each year. An analysis of the data on cases registered in three districts that reported approximately 70% of all malaria cases was performed, stratified by year, type of reporting health facilities and diagnostic method. Results: During 2008–2014, 50 487 cases of malaria were reported in Botswana, and the proportion of RDT and/or blood microscopy confirmed cases improved from 6% in 2008 to 89% in 2013. The total number of malaria cases decreased by 97% in the same period, then increased by 41% in 2013. Conclusion: This study shows that malaria diagnostic tests dramatically improved malaria diagnosis and consequently reduced the malaria burden in Botswana. The study identified a need to build capacity on microscopy for species identification, parasite quantification and guiding treatment choices. PMID:29713592

Validation of self-reported start year of mobile phone use in a Swedish case-control study on radiofrequency fields and acoustic neuroma risk.

The possible effect of radiofrequency exposure from mobile phones on tumor risk has been studied since the late 1990s. Yet, empirical information about recall of the start of mobile phone use among adult cases and controls has never been reported. Limited knowledge about recall errors hampers interpretations of the epidemiological evidence. We used network operator data to validate the self-reported start year of mobile phone use in a case-control study of mobile phone use and acoustic neuroma risk. The answers of 96 (29%) cases and 111 (22%) controls could be included in the validation. The larger proportion of cases reflects a more complete and detailed reporting of subscription history. Misclassification was substantial, with large random errors, small systematic errors, and no significant differences between cases and controls. The average difference between self-reported and operator start year was -0.62 (95% confidence interval: -1.42, 0.17) years for cases and -0.71 (-1.50, 0.07) years for controls, standard deviations were 3.92 and 4.17 years, respectively. Agreement between self-reported and operator-recorded data categorized into short, intermediate and long-term use was moderate (kappa statistic: 0.42). Should an association exist, dilution of risk estimates and distortion of exposure-response patterns for time since first mobile phone use could result from the large random errors in self-reported start year. Retrospective collection of operator data likely leads to a selection of "good reporters", with a higher proportion of cases. Thus, differential recall cannot be entirely excluded.

Case Report: Severe Imported Influenza Infections Developed during Travel in Reunion Island.

We report two cases of severe influenza infection imported by tourist patients from their country of origin and developed during travel. While studies have reported cases of influenza infections acquired during travel, here we examine two cases of severe influenza infection contracted in the country of origin that led to diagnosis and therapeutic problems in the destination country. No international recommendation exists concerning influenza vaccination before travel, and few countries recommend it for all travelers. Our study suggests that travel should be canceled when infectious signs are observed before departure. Influenza is a very common infection that is often benign, but sometimes very severe. The most severe cases include shock, acute respiratory distress syndrome (ARDS), myocarditis, rhabdomyolysis, and multiple organ failure. Management can require exceptional therapies, such as extracorporeal membrane oxygenation. A number of studies have focused on influenza infection in travelers. Cases of influenza acquired during travel have been reported in this literature, but no study has examined cases of influenza imported from the country of origin and developed while abroad. The latter situation may lead to 1) diagnostic problems during the nonepidemic season or in places where diagnostic techniques are lacking and 2) therapeutic difficulties resulting from the unavailability of techniques for the management of severe influenza infection in tourist areas. Here, we report two cases of extremely severe influenza infection imported by tourists from their country of origin and developed during travel.

2009-01-01

Since 1995 more than 1000 cases of hantavirus pulmonary syndrome (HPS) were reported in Argentina, a severe disease and often fatal to humans. Most cases were associated with Andes virus (AND) that caused few events of person-to-person transmission. Several lineages of pathogenic AND viruses have been described, including AND South, hosted by the rodent Oligoryzomys longicaudatus which affects the Patagonian region of Argentina and Chile. We studied the clinical and epidemiological characteristics of a HPS case. The objective was to describe the clinical presentation of the case, its epidemiology, the likely site of infection, the viral variant implicated and its relationship with the closest reported cases. We carried out the clinical follow up, serological and molecular diagnosis and the epidemiological research, including a rodent reservoir study. The clinical presentation of the case was the classical and moderate, caused by AND South virus. Its viral nucleotide sequence was compared with cases from Southern Argentina and Chile. This case was found to be the most Southern (48 degrees 46' 1.2'' S; 70 degrees 15' O) case reported and involved a new Argentinean province.

2014-08-29

The aim of this study was to describe the association between landscape and climate factors and the occurrence of tick paralysis cases in dogs and cats reported by veterinarians in Australia. Data were collated based on postcode of residence of the animal and the corresponding landscape (landcover and elevation) and climate (precipitation, temperature) information was derived. During the study period (October 2010-December 2012), a total of 5560 cases (4235 [76%] canine and 1325 [24%] feline cases) were reported from 341 postcodes, mostly along the eastern seaboard of Australia and from the states of New South Wales and Queensland. Significantly more cases were reported from postcodes which contained areas of broadleaved, evergreen tree coverage (P=0.0019); broadleaved, deciduous open tree coverage (P=0.0416); and water bodies (P=0.0394). Significantly fewer tick paralysis cases were reported from postcodes which contained areas of sparse herbaceous or sparse shrub coverage (P=0.0297) and areas that were cultivated and managed (P=0.0005). No significant (P=0.6998) correlation between number of tick paralysis cases reported per postcode and elevation was found. Strong positive correlations were found between number of cases reported per postcode and the annual minimum (rSP=0.9552, P<0.0001) and maximum (rSP=0.9075; P=0.0001) precipitation. Correlations between reported tick paralysis cases and temperature variables were much weaker than for precipitation, rSP<0.23. For maximum temperature, the strongest correlation between cases was found in winter (rSP=0.1877; P=0.0005) and for minimum temperature in autumn (rSP=0.2289: P<0.0001). Study findings suggest that tick paralysis cases are more likely to occur and be reported in certain eco-climatic zones, such as those with higher rainfall and containing tree cover and areas of water. Veterinarians and pet owners in these zones should be particularly alert for tick paralysis cases to maximize the benefits of early treatment, and to be vigilant to use chemical prophylaxis to reduce the risk of tick parasitism.

From diagnosis to case investigation for malaria elimination in Swaziland: is reporting and response timely?

PubMed

Dlamini, N; Zulu, Z; Kunene, S; Geoffroy, E; Ntshalintshali, N; Owiti, P; Sikhondze, W; Makadzange, K; Zachariah, R

2018-04-25

Background: Swaziland is one of the southern African countries that aim to eliminate malaria by 2020. In 2010, the country introduced an Immediate Disease Notification System (IDNS) for immediate reporting of notifiable diseases, including malaria. Health facilities are to report malaria cases within 24 h through a toll-free telephone number (977), triggering an alert for case investigation at the patient's household within 48 h. We assessed the completeness of reporting in the IDNS, the subsequent case investigation, and whether it was done within the stipulated timelines. Methods: A cross-sectional study using routine country-wide data. Results: Of 1991 malaria cases notified between July 2011 and June 2015, 76% were reported in the IDNS, of which 68% were investigated-a shortfall of 24% in reporting and 32% in case investigations. Of the 76% of cases reported through the IDNS, 62% were reported within 24 h and 20% were investigated within 48 h. These shortcomings were most pronounced in hospitals and private facilities. Investigated cases ( n = 1346) were classified as follows: 60% imported, 35% local and 5% undetermined. Conclusion: The utilisation of the IDNS for case reporting to trigger investigation is crucial for active surveillance. There is a need to address the reporting and investigation gaps identified to ensure that malaria cases receive appropriate interventions.

Case-control studies in neurosurgery.

PubMed

Nesvick, Cody L; Thompson, Clinton J; Boop, Frederick A; Klimo, Paul

2014-08-01

Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting. The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as "case-control" and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52-51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69-28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13-0.998) and use of the word "outcome" in the Results section (OR 0.23, 95% CI 0.082-0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure/intervention and true case-control studies was strengthened (OR 0.053, 95% CI 0.0064-0.44). There was a trend toward a negative association between the use of survival analysis or Kaplan-Meier curves and true case-control studies (OR 0.13, 95% CI 0.015-1.12). True case-control studies were no more likely than their counterparts to use a potential study design "expert" (OR 1.50, 95% CI 0.57-3.95). The overall average STROBE score was 72% (range 50-86%). Examples of reporting deficiencies were reporting of bias (28%), missing data (55%), and funding (44%). The results of this analysis show that the majority of studies in the neurosurgical literature that identify themselves as "case-control" studies are, in fact, labeled incorrectly. Positive and negative predictors were identified. The authors provide several recommendations that may reverse the incorrect and inappropriate use of the term "case-control" and improve the quality of design and reporting of true case-control studies in neurosurgery.

Poison control center experience with tianeptine: an unregulated pharmaceutical product with potential for abuse.

2018-05-25

Interest in tianeptine as a potential drug of abuse is increasing in the United States. We performed a retrospective study of calls to the New York State Poison Control Centers (PCCs) designed to characterize one state's experience with tianeptine. Data were gathered from existing records utilizing the poison center data collection system, Toxicall® entered between 1 January 2000 through 1 April 2017. Information regarding patient demographics, reported dose and formulation of tianeptine, reported coingestants, brief narrative description of the case, disposition, and case outcome was collected. There were nine reported cases of tianeptine exposure. Seven were male with a mean age of 27. Three reported therapeutic use of tianeptine and five reported intentional abuse. One case was an unintentional pediatric exposure. Doses were reported in three cases; 12.5 mg in a pediatric unintentional exposure, and 5 and 10 g daily in the two reports of intentional abuse. Of note, five patients complained of symptoms consistent with opioid withdrawal. In one of two cases in which naloxone was administered, an improvement in mental status and the respiratory drive was noted. Outcomes reported in Toxicall® were minor in two cases, moderate in five cases, major in one case, and not reported in one case. These cases, reported to the New York State PCCs should alert readers to the potential for tianeptine abuse, dependence, and withdrawal.

Abstract Objective: This was a systematic review and meta-analysis to determine the proportion of Escherichia coli O157 cases that develop chronic sequelae. Data Sources: We conducted a systematic review of articles published prior to July 2011 in Pubmed, Agricola, CabDirect, or Food Safety and Technology Abstracts. Study Selection: Studies were selected that reported the number of E. coli O157 cases that developed reactive arthritis (ReA), hemolytic uremic syndrome (HUS), irritable bowel syndrome, inflammatory bowel disease, or Guillain Barré syndrome. Methods: Three levels of screening and data extraction of articles were conducted using predefined data fields. Meta-analysis was performed on unique outcome measures using a random-effects model, and heterogeneity was assessed using the I2 value. Meta-regression was used to explore the influence of nine study-level variables on heterogeneity. Results: A total of 82 studies were identified reporting 141 different outcome measures; 81 reported on HUS and one reported on ReA. Depending on the number of cases of E. coli O157, the estimate for the proportion of E. coli O157 cases that develop HUS ranged from 17.2% in extra-small studies (<50 cases) to 4.2% in extra-large studies (>1000 cases). Heterogeneity was significantly associated with group size (p<0.0001); however, the majority of the heterogeneity was unexplained. Conclusions: High unexplained heterogeneity indicated that the study-level factors examined had a minimal influence on the variation of estimates reported. PMID:24404780

Imported malaria cases continue to occur and are often underreported. This study assessed reporting of malaria cases and their characteristics in Scotland. Cases were identified at the study sites of Aberdeen, Edinburgh, Glasgow and Inverness. The number of cases identified in the period 2003-2008 was compared to surveillance databases from Health Protection Scotland (HPS) and the Malaria Reference Laboratory (MRL). Case characteristics were recorded and analysed. Of 252 cases of malaria diagnosed and treated, an estimated 235 (93.3%) were reported to the MRL. Between 2006 and 2008, 114 of 126 cases (90.5%) were reported to HPS. Plasmodium falciparum caused 173 cases (68.7%). Business and professional travel accounted for 35.3% of cases (higher in Aberdeen), followed by visiting friends and relatives (33.1%) and holiday makers (25.5%). The majority of infections were imported from West Africa and 65.7% of patients for whom data on prophylaxis was available had taken no or inappropriate prophylaxis. Reporting of malaria in Scotland can be improved. There is a continued need to optimise preventive measures and adherence to chemoprophylaxis amongst business travellers, those visiting friends and relatives, and holiday makers in endemic countries in order to reduce imported malaria cases.

Unlike previous annual WHO tuberculosis reports that reported case detection rate for only smear-positive tuberculosis cases, the 2010 report presented case detection rate for all tuberculosis cases notified in line with the current Stop TB strategy. To help us understand how tuberculosis control programmes performed in terms of detecting tuberculosis, there is need to document the trend in case detection rate for all tuberculosis cases notified in high burden countries. This evidence is currently lacking from Nigeria. Therefore, this study aimed to assess the trend in case detection rate for all tuberculosis cases notified from Ebonyi state compared to Nigeria national figures. Reports of tuberculosis cases notified between 1999 and 2009 were reviewed from the Ebonyi State Ministry of Health tuberculosis quarterly reports. Tuberculosis case detection rates were computed according to WHO guidelines. 22, 508 patients with all forms of tuberculosis were notified during the study. Case detection rate for all tuberculosis rose from 27% in 1999 to gradually reach a peak of 40% during 2007 to 2008 before a slight decline in 2009 to 38%. However, the national case detection rate for all tuberculosis cases in Nigeria rose from 7% in 1999 and progressively increased to reach a peak of 19% during 2008 and 2009. Since the introduction of DOTS in Ebonyi, the programme has achieved 40% case detection rate for all tuberculosis cases - about 20% better than national figures. However, with the current low case detection rates, alternative mechanisms are needed to achieve the current global stop- TB targets in Nigeria.

Driving towards malaria elimination in Botswana by 2018: progress on case-based surveillance, 2013–2014

Background: Reliable information reporting systems ensure that all malaria cases are tested, treated and tracked to avoid further transmission. Botswana aimed to eliminate malaria by 2018, and surveillance is key. This study focused on assessing the uptake of the new malaria case-based surveillance (CBS) system introduced in 2012, which captures information on malaria cases reported in the Integrated Disease Surveillance and Response (IDSR) system. Methods: This was a retrospective descriptive study based on routine data focusing on Ngami, Chobe and Okavango, three high-risk districts in Botswana. Aggregated data variables were extracted from the IDSR and compared with data from the CBS. Results: The IDSR reported 456 malaria cases in 2013 and 1346 in 2014, of which respectively only 305 and 884 were reported by the CBS. The CBS reported 34% fewer cases than the IDSR system, indicating substantial differences between the two systems. The key malaria indicators with the greatest variability among the districts included in the study were case identification number and date of diagnosis. Conclusion: The IDSR and CBS systems are essential for malaria elimination, as shown by the significant gaps in reporting between the two systems. These findings highlight the need for further investigation into these discrepancies. Strengthening the CBS system will help to reach the objective of malaria elimination in Botswana. PMID:29713590

Background: Reliable information reporting systems ensure that all malaria cases are tested, treated and tracked to avoid further transmission. Botswana aimed to eliminate malaria by 2018, and surveillance is key. This study focused on assessing the uptake of the new malaria case-based surveillance (CBS) system introduced in 2012, which captures information on malaria cases reported in the Integrated Disease Surveillance and Response (IDSR) system. Methods: This was a retrospective descriptive study based on routine data focusing on Ngami, Chobe and Okavango, three high-risk districts in Botswana. Aggregated data variables were extracted from the IDSR and compared with data from the CBS. Results: The IDSR reported 456 malaria cases in 2013 and 1346 in 2014, of which respectively only 305 and 884 were reported by the CBS. The CBS reported 34% fewer cases than the IDSR system, indicating substantial differences between the two systems. The key malaria indicators with the greatest variability among the districts included in the study were case identification number and date of diagnosis. Conclusion: The IDSR and CBS systems are essential for malaria elimination, as shown by the significant gaps in reporting between the two systems. These findings highlight the need for further investigation into these discrepancies. Strengthening the CBS system will help to reach the objective of malaria elimination in Botswana.

The U.K.'s "Dash for Gas".

PubMed

Watterson, Andrew; Dinan, William

2017-05-01

The evidence on public health regulation of the unconventional gas extraction (fracking) industry was examined using a rapid evidence assessment of fifteen case studies from multiple countries. They included scientific and academic papers, professional reports, government agency reports, industry and industry-funded reports, and a nongovernment organization report. Each case study review was structured to address strengths and weaknesses of the publication in relation to our research questions. Some case studies emphasized inherent industry short-, medium-, and long-term dangers to public health directly and through global climate change impacts. Other case studies argued that fracking could be conducted safely assuming industry best practice, "robust" regulation, and mitigation, but the evidence base for such statements proved generally sparse. U.K. regulators' own assessments on fracking regulation are also evaluated. The existing evidence points to the necessity of a precautionary approach to protect public health from unconventional gas extraction development.

This study aims to evaluate the effectiveness of pre-travel counselling carried out in Travel Clinics. This is a retrospective cohort. Three hundred international travellers were enrolled; 150 people were from users of Bari Travel Clinic, 150 were users of a travel agency. Enrolled subjects were interviewed using a questionnaire. The average age of the enrolled subjects was 37.5 ± 13.9, without statistically significant differences between the two groups. 86% of cases and 19.3% of the controls reported the use of anti-malaria prophylaxis (p < 0.0001). Vaccination against cholera was given to 62% of cases and 7.3% of the controls (p < 0.001). Travel Clinic users, 6% reported diarrhoea and these figures were 27% in the control group (p < 0.0001). The proportion of those interviewed who reported fever (3.7) or insomnia (1.3) did not differ between the two groups. Mosquito bites were reported by 8% of cases and 20% of the controls (p = 0.003). Three cases of malaria were reported among the controls but no cases were detected among the cases (chi-square = 3.03; p = 0.08). Our study demonstrated the effectiveness of pre-travel counselling; in the future, new studies must investigate the cost-effectiveness of pre-travel prevention measures.

Multi-level factors influence the implementation and use of complex innovations in cancer care: a multiple case study of synoptic reporting.

Urquhart, Robin; Porter, Geoffrey A; Sargeant, Joan; Jackson, Lois; Grunfeld, Eva

2014-09-16

The implementation of innovations (i.e., new tools and practices) in healthcare organizations remains a significant challenge. The objective of this study was to examine the key interpersonal, organizational, and system level factors that influenced the implementation and use of synoptic reporting tools in three specific areas of cancer care. Using case study methodology, we studied three cases in Nova Scotia, Canada, wherein synoptic reporting tools were implemented within clinical departments/programs. Synoptic reporting tools capture and present information about a medical or surgical procedure in a structured, checklist-like format and typically report only items critical for understanding the disease and subsequent impacts on patient care. Data were collected through semi-structured interviews with key informants, document analysis, nonparticipant observation, and tool use/examination. Analysis involved production of case histories, in-depth analysis of each case, and a cross-case analysis. Numerous techniques were used during the research design, data collection, and data analysis stages to increase the rigour of this study. The analysis revealed five common factors that were particularly influential to implementation and use of synoptic reporting tools across the three cases: stakeholder involvement, managing the change process (e.g., building demand, communication, training and support), champions and respected colleagues, administrative and managerial support, and innovation attributes (e.g., complexity, compatibility with interests and values). The direction of influence (facilitating or impeding) of each of these factors differed across and within cases. The findings demonstrate the importance of a multi-level contextual analysis to gaining both breadth and depth to our understanding of innovation implementation and use in health care. They also provide new insights into several important issues under-reported in the literature on moving innovations into healthcare practice, including the role of middle managers in implementation efforts and the importance of attending to the interpersonal aspects of implementation.

2017-10-31

Case-non case studies belongs to the methods assessing drug safety by analyzing the disproportionality of notifications of adverse drug reactions in pharmacovigilance databases. Used for the first time in the 1980s, the last few decades have seen a significant increase in the use of this design. The principle of the case-non case study is to compare drug exposure in cases of a studied adverse reaction with that of cases of other reported adverse reactions and called "non cases". Results are presented in the form of a reporting odds ratio (ROR), the interpretation of which makes it possible to identify drug safety signals. This article describes the principle of the case-non case study, the method of calculating the ROR and its confidence interval, the different modalities of analysis and how to interpret its results with regard to the advantages and limitations of this design.

Pollard, D; Wylie, C E; Verheyen, K L P; Newton, J R

2017-11-01

Use of owner-reported data could further epidemiological knowledge of equine laminitis. However, owner recognition of laminitis has not previously been assessed. The primary objective was to establish whether cases of owner-suspected laminitis would be confirmed as laminitis by the attending veterinary surgeon. Secondary objectives were to compare owner- and veterinary-reported information from veterinary-confirmed cases of equine laminitis. Cross-sectional study. Twenty-five British veterinary practices were invited to submit laminitis reporting forms (LRFs) for active laminitis cases attended between January 2014 and October 2015; detailing 27 clinical signs, 5 underlying conditions and 7 risk factors associated with laminitis. Owners were invited to independently complete a modified LRF if reason for the veterinary visit was suspicion of laminitis. Differences between paired veterinary and owner LRFs, and between cases where owners did and did not recognise laminitis, were assessed using McNemar's and Fisher's Exact tests, respectively. Veterinary LRFs were received for 93 veterinary-diagnosed laminitis cases. All 51 owner-suspected cases were confirmed by veterinary diagnosis, with the remaining 42 (45.2%) not recognised as laminitis by owners. Undefined lameness, foot abscesses, colic and stiffness were common reasons for owner-requested veterinary visits in owner-unrecognised cases. 'Divergent growth rings' (prevalence difference: +27.3%, P = 0.01) and 'breed type' (prevalence difference: +21.2%, P = 0.04) were more commonly reported by veterinary surgeons in owner-recognised compared to owner-unrecognised cases. 'Difficulty turning', 'shifting weight' and risk factor 'body condition' were more frequently reported by veterinary surgeons whilst 'increased hoof temperature' was reported more frequently by owners. The limited clinical data restricted statistical inferences regarding the secondary objectives. All owner-suspected laminitis cases were confirmed upon veterinary examination, showing validity for the inclusion of owner-reported cases in future epidemiological studies. However, failure of laminitis recognition by owners highlights further need for evidence-based education to ensure early disease detection. © 2017 EVJ Ltd.

Consummated mother-son incest in latency: a case report of an adult analysis.

2002-01-01

Reported cases of mother-son incest are very rare in the psychoanalytic literature; the fact of such incest, however, may not be so rare as has generally been believed. A detailed case report of the analysis of an adult with a history of severe physical, sexual, and verbal abuse, including consummated incest with his mother during latency, is considered in the context of other reported studies. The author raises some issues of resistance and countertransference that may influence the reporting, treatment, and perhaps even recognition of cases of mother-son incest.

The objective of this study was to determine factors associated with syphilis among men who report sex with other men in New York City. DESIGN, SETTING AND STUDY SUBJECTS: We conducted a case-control study among 88 men who reported sex with men in the previous year, 18 to 55 years old and diagnosed with primary or secondary syphilis during 2001; and 176 control subjects frequently matched by age and type of health provider. HIV prevalence among syphilis cases was 48% compared with 15% among control subjects (P <0.001). Variables associated with syphilis in a multivariate model were HIV infection (odds ratio [OR], 7.3; 95% confidence interval [CI], 3.5-15.4), income >$30,000 per year (OR, 2.7; CI, 1.4-5.2), and barebacking (OR, 2.6; CI, 1.4-4.8). The median time since HIV diagnosis for HIV-positive was 6 years for cases and 7 years for control subjects (P = 0.70). Among HIV-infected participants, syphilis cases were more likely than control subjects to report being on antiretroviral therapy (69% vs. 44%, P = 0.05) and to report having undetectable viral load (58% vs. 24%, P = 0.02). HIV infection was strongly associated with syphilis in this study. High-risk behavior reported by both cases and control subjects indicates the potential for increased HIV transmission.

Background: Swaziland is one of the southern African countries that aim to eliminate malaria by 2020. In 2010, the country introduced an Immediate Disease Notification System (IDNS) for immediate reporting of notifiable diseases, including malaria. Health facilities are to report malaria cases within 24 h through a toll-free telephone number (977), triggering an alert for case investigation at the patient's household within 48 h. We assessed the completeness of reporting in the IDNS, the subsequent case investigation, and whether it was done within the stipulated timelines. Methods: A cross-sectional study using routine country-wide data. Results: Of 1991 malaria cases notified between July 2011 and June 2015, 76% were reported in the IDNS, of which 68% were investigated—a shortfall of 24% in reporting and 32% in case investigations. Of the 76% of cases reported through the IDNS, 62% were reported within 24 h and 20% were investigated within 48 h. These shortcomings were most pronounced in hospitals and private facilities. Investigated cases (n = 1346) were classified as follows: 60% imported, 35% local and 5% undetermined. Conclusion: The utilisation of the IDNS for case reporting to trigger investigation is crucial for active surveillance. There is a need to address the reporting and investigation gaps identified to ensure that malaria cases receive appropriate interventions. PMID:29713587

2014-06-15

Purpose: This work offers as a teaching example a reported high dose fluoroscopy case and the workflow the institution followed to self-report a radiation overdose sentinel event to the Joint Commission. Methods: Following the completion of a clinical case in a hybrid OR room with a reported air kerma of >18 Gy at the Interventional Reference Point (IRP) the physicians involved in the case referred study to the institution's Radiation Safety Committee (RSC) for review. The RSC assigned a Diagnostic Medical Physicist (DMP) to estimate the patient's Peak Skin Dose (PSD) and analyze the case. Following the DMP's analysis andmore » estimate of a PSD of >15 Gy the institution's adverse event committee was convened to discuss the case and to self-report the case as a radiation overdose sentinel event to the Joint Commission. The committee assigned a subgroup to perform the root cause analysis and develop institutional responses to the event. Results: The self-reporting of the sentinel event and the associated root cause analysis resulted in several institutional action items that are designed to improve process and safety. A formal reporting and analysis mechanism was adopted to review fluoroscopy cases with air kerma greater than 6 Gy at the IRP. An improved and formalized radiation safety training program for physicians using fluoroscopy equipment was implemented. Additionally efforts already under way to monitor radiation exposure in the Radiology department were expanded to include all fluoroscopy equipment capable of automated dose reporting. Conclusion: The adverse event review process and the root cause analysis following the self-reporting of the sentinel event resulted in policies and procedures that are expected to improve the quality and safe usage of fluoroscopy throughout the institution.« less

In 1984 the Venezuelan Work Groups in Mycology (VWGM) were created introducing an innovative approach to the study of the mycoses in Venezuela. To study the occurrence of the mycoses in Venezuela. Review the reported cases of mycoses by the newsletter Boletín Informativo Las Micosis en Venezuela (VWGM) from 1984 to 2010. The data collected showed 36,968 reported cases of superficial mycoses, 1,989 of deep systemic cases, and 822 of localized mycoses. Pityriasis dermatophytosis was the most common superficial infection, and paracoccidioidomycosis and histoplasmosis the most frequent deep systemic infection. Chromoblastomycosis was the most frequently diagnosed subcutaneous infection. The data provided showed the distribution by geographical area for each of the fungal infections studied, which may help to establish the endemic areas. Superficial mycosis is a public health problem due to its high morbidity and is probably responsible for some of the outbreaks in high-risk groups. Paracoccidioidomycosis and histoplasmosis were reported more often, which agrees with earlier reports prior to the formation of the VWGM. Cases of sporotrichosis and chromoblastomycosis in Venezuela can be considered unique due to the high number of cases. This study highlights the contribution of the VWGM to the behavior of the mycoses in Venezuela, its incidence, prevalence, and the recognition of these infections as a problem of public health importance. The VWGM should keep working in this endeavor, not only reporting new cases, but also unifying the clinical and epidemiological criteria, in order to properly monitor the evolving epidemiological changes reported in these types of infections.

Case Reports, Case Series - From Clinical Practice to Evidence-Based Medicine in Graduate Medical Education.

PubMed

Sayre, Jerry W; Toklu, Hale Z; Ye, Fan; Mazza, Joseph; Yale, Steven

2017-08-07

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.

Selective reporting of antibiotic susceptibility test (AST) results is a potential intervention for laboratory-based antibiotic stewardship. The aim of this study was to assess the impact of AST reporting on the appropriateness of antibiotics selected by French general practitioners for urinary tract infections (UTIs). A randomised controlled case-vignette study in a region of northeast France surveyed general practitioners between July and October 2015 on treatment of four clinical cases of community-acquired Escherichia coli UTIs (two cases of complicated cystitis, one of acute pyelonephritis and one male UTI). In Group A, selective reporting of AST results was used for the first two cases and complete reporting for the other two cases; these were reversed in Group B. The overall participation rate was 131/198 (66.2%). Provision of selective AST results significantly increased the rate of adherence to national guidelines for first-line antibiotic treatment in Cases 1, 3 and 4 by 22.4% (55.2% vs. 32.8%, P = 0.01), 67.5% (75.0% vs. 7.5%, P <0.001) and 36.3% (45.3% vs. 9.0%, P <0.001), respectively. The improvement in compliance was not significant for Case 2. Prescriptions of amoxicillin-clavulanic acid, fluoroquinolones and cephalosporins decreased by 25.0% to 45.0%, depending on the clinical vignette. Most (106/131, 81.0%) participants favoured the routine use of selective reporting of AST results. In conclusion, selective reporting of AST results seems to improve antibiotic prescribing practices in primary care, and may be considered a key element of antimicrobial stewardship programmes.

The use of Latin terminology in medical case reports: quantitative, structural, and thematic analysis.

PubMed

Lysanets, Yuliia V; Bieliaieva, Olena M

2018-02-23

This paper focuses on the prevalence of Latin terms and terminological collocations in the issues of Journal of Medical Case Reports (February 2007-August 2017) and discusses the role of Latin terminology in the contemporary process of writing medical case reports. The objective of the research is to study the frequency of using Latin terminology in English-language medical case reports, thus providing relevant guidelines for medical professionals who deal with this genre and drawing their attention to the peculiarities of using Latin in case reports. The selected medical case reports are considered, using methods of quantitative examination and structural, narrative, and contextual analyses. We developed structural and thematic typologies of Latin terms and expressions, and we conducted a quantitative analysis that enabled us to observe the tendencies in using these lexical units in medical case reports. The research revealed that the use of Latin fully complies with the communicative strategies of medical case reports as a genre. Owing to the fact that Latin medical lexis is internationally adopted and understood worldwide, it promotes the conciseness of medical case reports, as well as contributes to their narrative style and educational intentions. The adequate use of Latin terms in medical case reports is an essential prerequisite of effective sharing of one's clinical findings with fellow researchers from all over the world. Therefore, it is highly important to draw students' attention to Latin terms and expressions that are used in medical case reports most frequently. Hence, the analysis of structural, thematic, and contextual features of Latin terms in case reports should be an integral part of curricula at medical universities.

Study Design Case report. Objective Incidental durotomy (IDT) is a common complication of spinal surgery. The use of collagen matrix graft along with hydrogel dural sealant is a common method of IDT repair. With this method, there have been several reported cases of detrimental dural sealant expansion in the literature. One case study reported an expansion rate greater than 300%; many report neurologic damage. This article reports the clinical course of two patients who developed postoperative transcutaneous drainage of a gel-like substance after the use of a dural sealant, which is a previously unreported complication. Methods The clinical course and treatment outcome of two patients is presented. Results Both patients experienced postoperative transcutaneous drainage of a gel-like substance at the surgical site. Case one began draining this substance on postoperative day 14. This patient required no further intervention, and the drainage ended after 3 mL of a gel-like substance was expressed from his incision while in the clinic. Case two began draining the gel on postoperative day 16. This patient underwent two washout procedures and resolution of the drainage. No infection was ever detected. Conclusions To our knowledge, our patients are the first reported cases of transcutaneous drainage of expanded dural sealant. It is important to take into consideration the unexpected expansion of a dural sealant when using it for the repair of IDT.

Case reports are often regarded as second-class research, but are an important part of medical science as they often present first evidence of new discoveries. We here describe the type of case reports published in a Danish general medical journal. We included all case reports published in Ugeskrift for Laeger in 2009. For each report, two authors extracted information on study characteristics and classified the relevance and the role of the report. We included 139 case reports written in Danish. Thirty-nine (28%) were of general relevance and 100 (72%) of speciality relevance. The median number of authors was three (range: 1-7). The first author was a non-specialist physician in 119 (86%) of the reports and the last author a specialist in 103 (78%). A total of 124 (89%) reports had an educational role, six (4%) dealt with new diseases, two (1%) with new side effects, three (2%) with new mechanisms and four (3%) were curiosities. A total of 59 (42%) reports were surgical, 64 (46%) non-surgical and 16 (12%) paraclinical. We found that most case reports published in Ugeskrift for Laeger were of speciality relevance and had an educational perspective. The journal may consider focusing on cases of more general educational relevance and should also consider whether the current form and language suit the aim and role of the various types of case reports.

A third of the world population is infected with tuberculosis (TB) bacilli. TB accounts for 25% of all avoidable deaths in developing countries. The objective of the study was to assess impact of directly observed treatment short-course (DOTS) strategy on new tuberculosis case finding and treatment outcomes in Somali Regional State, Ethiopia from 2003 up to 2012 and from 2004 up to 2013, respectively. A health facility based retrospective study was employed. Quarterly reports were collected using World Health Organization (WHO) reporting format for TB case finding and treatment outcome from all zones in the region to the Federal Ministry of Health. A total of 31, 198 all types of new TB cases were registered and reported during the period from 2003 up to 2012, in the region. Out of these, smear positive pulmonary TB cases were 12,466 (40%), and 10,537 (33.8%) and 8195 (26.2%) for smear negative pulmonary TB and extra-pulmonary TB cases, respectively. An average case detection rate (CDR) of 19.1% (SD 3.6) and treatment success rate (TSR) of 85.5% (SD 5.0) for smear positive pulmonary TB were reported for the specified years period. For the overall study period, trend chi-squire analysis for CDR was X(2) = 2.1; P > 0.05 and X(2) = 5.64; P < 0.05 for TSR. The recommended TSR set by WHO was achieved (85.5%) and the CDR reported was far below (19.1%) from the recommended target. Extensive efforts should be established to maintain the achieved TSR and to increase the low CDR for the smear positive pulmonary TB cases through implementing alternative case finding strategies.

The 3-M syndrome is a rare autosomal recessive disorder. It is characterized by prenatal and postnatal growth retardation associated with characteristic features. In this study, we report on three patients from two unrelated families, including two male sibs, with the characteristic features and radiological findings of the 3-M syndrome. The main features in our cases were low birth weight, short stature, malar hypoplasia, anteverted nostrils with a fleshy nasal tip, long philtrum, pointed full chin, short broad neck, broad chest with transverse grooves of anterior thorax and hyperlordosis. An orodental examination revealed characteristic findings, some of which were not reported before. Prominent premaxilla, hypoplastic maxilla, thick patulous lips, high-arched palate, median fissured tongue, delayed eruption of teeth with enamel hypocalcification and malocclusion were present in our three studied cases. Radiographic studies showed slender long bones and ribs, a narrow pelvis and foreshortened vertebral bodies. Our reported cases are the offspring of healthy consanguineous parents, confirming the autosomal recessive pattern of inheritance in the syndrome. Cases were reported from different countries all over the world. To our knowledge, these are the first reported Egyptian patients with this rare disorder. This syndrome may be underreported because of the phenotypic overlap with other low birth dwarfism syndromes. Recent identification of a gene mutated in some cases of 3-M syndrome will aid diagnosis.

Case-control studies are important in developing clinical and public health knowledge. The STROBE statement (STrengthening the Reporting of OBservational Studies in Epidemiology) was developed to establish a checklist of items that should be included in articles reporting observational studies. Our aim was to analyze whether the psychiatric case-control articles published in Brazilian journals with CAPES Qualis rating B1/B2 in 2009 conformed with the STROBE statement. Descriptive study on psychiatric papers published in Brazilian journals, within the Postgraduate Medical Program on Psychiatry, at Universidade Federal do Rio Grande do Sul. All psychiatric case-control studies from Brazilian Qualis B1/B2 journals of psychiatry, neurology and public health in 2009 were analyzed. The four most specific items of the STROBE statement were used to evaluate whether these studies fitted within the case-control parameters: 1) selection of cases and controls; 2) controlling for bias; 3) statistical analysis; and 4) presentation of results. Sixteen case-control studies were identified, of which eleven (68.75%) were in psychiatry-focused journals. From analysis using the STROBE statement, all of the articles conformed with item 1; two (12.5%) completely conformed with item 2; none completely conformed with item 3; and only three (18.8%) conformed with item 4. The case-control studies analyzed here did not completely conform with the four STROBE statement items for case-control design. In view of the inadequate methodology of the published studies, these findings justify focusing on research and methodology and expanding the investigations on adherence of studies to their designs.

Case-control studies (CCS) and cohort studies (CS) are common research designs in neurosurgery. But the term case-control study is frequently misused in the neurosurgical literature, with many articles reported as CCS, even although their methodology does not respect the basic components of a CCS. We sought to estimate the extent of these discrepancies in neurosurgical literature, explore factors contributing to mislabeling, and shed some light on study design reporting. We identified 31 top-ranking pure neurosurgical journals and searched them for articles reported as CCS, either in the title or in the abstract. The articles were read to determine if they really were CCS according to STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. Article assessment was conducted in duplicate (agreement [κ statistics] = 99.82%). Two hundred and twenty-four articles met our inclusion criteria, 133 of which (59.38%) correctly labeled the case-control design, whereas 91 (40.62%) misclassified this study design. Cohort studies (CS) were the most common design mislabeled as case-control studies in 76 articles (33.93%), 57 of which (25.45%) were retrospective CS. The mislabeling of CCS impairs the appropriate indexing, classification, and sorting of evidence. Mislabeling CS for CCS leads to a downgrading of evidence as CS represent the highest level of evidence for observational studies. Odds ratios instead of relative risk are reported for these studies, resulting in a distortion of the measurement of the effect size, compounded when these are summarized in systematic reviews and pooled in meta-analyses. Many studies reported as CCS are not true CCS. Reporting guidelines should include items that ensure that studies are labeled correctly. STROBE guidelines should be implemented in assessment of observational studies. Researchers in neurosurgery need better training in research methods and terminology. We also recommend accrued vigilance from reviewers and editors. Copyright © 2018 Elsevier Inc. All rights reserved.

Park, S H; Chung, H S; Song, S H

2015-10-01

This study aimed to analyze the clinical features of lumbar hernia reported in South Korea and compare these features with those reported in foreign literature. From January 1968 through December 2013, 13 cases reported in South Korea were included in the study. The variables compared were age, sex, main symptoms at hospital visit, etiology, location, herniated contents, lateralization, defect size, diagnostic methods, surgical methods, surgical opinions, and recurrence. In the South Korean cases, women outnumbered men (3.3:1) and no significant differences were found in the herniated side (left:right, 1.1:1). In contrast, in the foreign cases, men outnumbered women (3:1) and left-sided hernia was dominant (2:1). Moreover, in most of the foreign cases, patients were aged 50-70 years, whereas in the South Korean cases, none of the patients were in their 50 s. However, no substantial differences were found in etiology, anatomical locations, symptoms, and herniated contents. This research revealed that few clinical features of lumbar hernias in South Korea differ from those reported in foreign literature. Thirteen cases were analyzed in the present study, and results obtained from such a small sample size cannot be generalized with certainty. Therefore, more cases should be collected for a definitive analysis. Despite this limitation, this study is important because it is the first attempt to collect and analyze the clinical features of lumbar hernia in South Korea. This study will serve as a basis for future studies investigating the clinical features of lumbar hernia cases in South Korea.

Unintentional Epinephrine Auto-injector Injuries: A National Poison Center Observational Study.

Epinephrine is the only first-line therapeutic agent used to treat life-threatening anaphylaxis. Epinephrine auto-injectors are commonly carried by patients at risk for anaphylaxis, and reported cases of unintentional auto-injector injury have increased over the last decade. Modifications of existing designs and release of a new style of auto-injector are intended to reduce epinephrine auto-injector misuse. The aim of the study was to characterize reported cases of unintentional epinephrine auto-injector exposures from 2013 to 2014 and compare demographics, auto-injector model, and anatomical site of such exposures. The American Association of Poison Control Center's National Poison Data System was searched from January 1, 2013, to December 31, 2014, for cases of unintentional epinephrine auto-injector exposures. Anatomical site data were obtained from all cases reported to the Virginia Poison Center and participating regional poison center for Auvi-Q cases. A total of 6806 cases of unintentional epinephrine auto-injector exposures were reported to US Poison Centers in 2013 and 2014. Of these cases, 3933 occurred with EpiPen, 2829 with EpiPen Jr, 44 with Auvi-Q, and no case reported of Adrenaclick. The most common site of unintentional injection for traditional epinephrine auto-injectors was the digit or thumb, with 58% of cases for EpiPen and 39% of cases with EpiPen Jr. With Auvi-Q, the most common site was the leg (78% of cases). The number of unintentional epinephrine auto-injector cases reported to American Poison Centers in 2013-2014 has increased compared with previous data. Most EpiPen exposures were in the digits, whereas Auvi-Q was most frequently in the leg. Because of the limitations of Poison Center data, more research is needed to identify incidence of unintentional exposures and the effectiveness of epinephrine auto-injector redesign.

Electronic reporting of Influenza-like illness (eILI) from primary care was implemented and evaluated in three general medical practices in New Zealand during May to September 2015. To measure the uptake of eILI and to identify the system's strength and limitations. Analysis of transactional data from the eILI system; comparative study of influenza-like illness cases reported using manual methods and eILI; questionnaire administered to clinical and operational stakeholders. Over the study period 66% of total ILI cases were reported using eILI. Reporting timeliness improved significantly compared to manual reporting with an average of 24 minutes from submission by the clinician to processing in the national database. Users found the system to be user-friendly. eILI assists clinicians to report ILI cases to public health authorities within a stipulated time period and is associated with faster, more reliable and improved information transfer.

Gestational diabetes insipidus (GDI) refers to the state of excessive water intake and hypotonic polyuria. Those cases manifesting in pregnancy and referred to as GDI may persist thereafter or may be a transient latent form that resolves after delivery. Microscopic examination of affected subjects has not been previously reported. In the literature, there are various case reports and case series on diabetes insipidus in pregnancy. In this study, we present a case that had transient diabetes insipidus during pregnancy in which the placenta was examined.

Under-reporting of tuberculosis in Praia, Cape Verde, from 2006 to 2012.

According to World Health Organization (WHO) estimates, the under-reporting rate for tuberculosis (TB) in Cape Verde between 2006 and 2012 was 49%. However, the WHO recognises the challenges associated with this estimation process and recommends implementing other methods, such as record linkage, to combat TB under-reporting. To estimate and analyse under-reporting of cases by TB surveillance health units and to evaluate TB cases retrieved from other TB diagnostic sources in Praia, Cape Verde, from 2006 to 2012. This cross-sectional study evaluated under-reporting using the following data: 1) the under-reporting index from TB reporting health units (RHUs), where the number of validated TB cases from RHUs was compared with data from the National Programme for the Fight against Tuberculosis and Leprosy (NPFTL); and 2) the under-reporting index among overall data sources, or a comparison of the number of all validated TB cases from all sources with NPFTL data. The TB under-reporting rate was 40% in Praia during the study period, and results were influenced by laboratory findings. The TB under-reporting rate was very similar to the rate estimated by the WHO. TB surveillance must be improved to reduce under-reporting.

This study aimed to determine the incidence, clinical features and management of cicatrising conjunctivitis in Australia and New Zealand, also enabling comparison with data from the United Kingdom. A prospective surveillance study was conducted over 17 months via the Australian and New Zealand Ophthalmic Surveillance Unit with a one-year follow-up period. Practicing ophthalmologists on the Surveillance Unit's database were asked to report recently diagnosed cases of cicatrising conjunctivitis on a monthly basis. Initial and follow-up questionnaires were sent to ophthalmologists who had reported positive cases to obtain demographic and clinical data. The minimum incidence of cicatrising conjunctivitis was calculated based on cases reported during the study period and from population data. During the 17-month study period (December 2011-April 2013), 56 cases of cicatrising conjunctivitis were reported. Data was obtained for 35 cases (62%) with a mean age of 74 years (range, 28-94 years). The most common aetiologies were ocular mucus membrane pemphigoid (n = 18 cases, 51.4%), Stevens-Johnson Syndrome (n = 3, 8.6%) and graft versus host disease (n = 3, 8.6%). The minimum incidence of cicatrising conjunctivitis in Australia and New Zealand was 1.5 per million, comparable to incidence data from the United Kingdom. This study is the first to prospectively record the incidence of cicatrising conjunctivitis in Australia and New Zealand and the second worldwide. It provides novel data on demographics and management of cicatrising conjunctivitis, as reported by treating ophthalmologists.

To evaluate the quality of reporting in the neovascular age-related macular degeneration (nvAMD) literature by applying the Consolidated Standards for Reporting Trials (CONSORT) and Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement writing standards. CONSORT and STROBE impact analysis; literature review. Phase III randomized controlled trials (RCTs) of verteporfin photodynamic therapy, pegaptanib, and ranibizumab, and interventional case studies of bevacizumab for nvAMD. A literature search identified eligible articles published before October 31, 2007. We assessed the report quality of Phase III RCTs using the CONSORT statement and case series publications using the STROBE statement, both with indicators relevant to nvAMD. Presence or absence of CONSORT or STROBE statement indicators. Seven publications of Phase III RCTs and 29 publications on bevacizumab interventional case studies for nvAMD met our inclusion criteria. Of 37 possible CONSORT writing guideline items, the mean report quality for RCTs was 30.6 (83%), with a range from 23 to 35 (65%-95%). Of 35 possible STROBE writing guideline items, the mean report quality grade for intravitreal bevacizumab case series was 23 (70%), with a range from 16 to 31 (46%-94%). Among the bevacizumab studies, more than 90% reported scientific background, drug dose and administration, baseline characteristics, unadjusted results, and adverse events. Fewer than 20% reported study size calculations, handling of missing data, or a discussion of bias. Since the adoption of the CONSORT standards by Ophthalmology and other journals in 1996, the reporting quality for RCTs has further improved among this cohort of nvAMD articles. On the other hand, no reporting standards for case series have existed until the recent publication of the STROBE statement. In this first application of the STROBE standards to ophthalmology, we found that the small interventional studies in our series had an average reporting score lower than the RCTs, but also that some individual scores were higher than the RCTs. This outcome demonstrates that good, useful articles can be written about small studies. Although not a direct measure of the quality of a study, good reporting allows a reader to assess the validity and applicability of the study's findings.

Sialolipoma is a rare neoplasm of salivary glands, described as a distinct entity by Nagao et al. in 2001. Thirty-six cases of sialolipoma in minor and major salivary glands have been reported thus far in addition to the two new cases of sialolipoma arising in the major salivary glands in this study. Thirty-six cases of sialolipoma published in English language reports were analyzed considering gender, age, location, size, duration of symptoms, treatment mode, follow-up, and histologic findings. Congenital sialolipomas were considered in this study. The first case occurred in a 45-year-old female and presented as a localized swelling in right parotid area. The second case occurred in an 18-year-old female as a swelling in the left parotid region. On histopathological examination, these lesions were diagnosed as sialolipoma. PMID:23878570

Information about ADRs explored by pharmacovigilance approaches: a qualitative review of studies on antibiotics, SSRIs and NSAIDs

Background Despite surveillance efforts, unexpected and serious adverse drug reactions (ADRs) repeatedly occur after marketing. The aim of this article is to analyse ADRs reported by available ADR signal detection approaches and to explore which information about new and unexpected ADRs these approaches have detected. Methods We selected three therapeutic cases for the review: antibiotics for systemic use, non-steroidal anti-inflammatory medicines (NSAID) and selective serotonin re-uptake inhibitors (SSRI). These groups are widely used and represent different therapeutic classes of medicines. The ADR studies were identified through literature search in Medline and Embase. The search was conducted in July 2007. For each therapeutic case, we analysed the time of publication, the strengths of the evidence of safety in the different approaches, reported ADRs and whether the studies have produced new information about ADRs compared to the information available at the time of marketing. Results 79 studies were eligible for inclusion in the analysis: 23 antibiotics studies, 35 NSAID studies, 20 SSRI studies. Studies were mainly published from the end of the 1990s and onwards. Although the drugs were launched in different decades, both analytical and observational approaches to ADR studies were similar for all three therapeutic cases: antibiotics, NSAIDs and SSRIs. The studies primarily dealt with analyses of ADRs of the type A and B and to a lesser extent C and D, cf. Rawlins' classification system. The therapeutic cases provided similar results with regard to detecting information about new ADRs despite different time periods and organs attacked. Approaches ranging higher in the evidence hierarchy provided information about risks of already known or expected ADRs, while information about new and previously unknown ADRs was only detected by case reports, the lowest ranking approach in the evidence hierarchy. Conclusion Although the medicines were launched in different decades, approaches to the ADR studies were similar for all three therapeutic cases: antibiotics, NSAIDs and SSRIs. Both descriptive and analytical designs were applied. Despite the fact that analytical studies rank higher in the evidence hierarchy, only the lower ranking descriptive case reports/spontaneous reports provided information about new and previously undetected ADRs. This review underscores the importance of systems for spontaneous reporting of ADRs. Therefore, spontaneous reporting should be encouraged further and the information in ADR databases should continuously be subjected to systematic analysis. PMID:19254390

This study aims to describe the frequency and quality of spontaneous narcolepsy case reports following administration of pandemic influenza vaccine as captured in the Eudravigilance database. We conducted a retrospective descriptive study of spontaneous Individual Case Safety Reports (ICSRs), reporting narcolepsy following administration of pandemic influenza vaccine as received by Eudravigilance until July 2014. De-duplication was carried out by Eudravigilance. Frequency of reporting is described as number of ICSRs received per month over time. The quality of the ICSRs was evaluated by completeness of information and diagnostic certainty using the Automated Brighton Collaboration case definition tool (ABC-tool) for narcolepsy. After de-duplication, a total of 1333 ICSRs of narcolepsy and/or cataplexy following pandemic influenza vaccine were identified, originating from 18 countries worldwide. Most of the ICSRs (61.9%) originated from the signaling countries, Sweden and Finland. Although de-duplication of case reports was carried out, it is suspected that many duplicates exist, in particular from Sweden. The majority of the ICSRs (95.3%), reported exposure to Pandemrix®. Only few reports were received for Arepanrix® (1.6%) or Focetria® (0.5%), and Celvapan® (0.1%). Of those ICSRs reporting age, 73.1% concerned persons below age of 20years. When using the ABC-tool, all ICSRs were classified as having insufficient information to meet the Brighton Collaboration case definition of narcolepsy. An increase in reporting of narcolepsy appeared in Eudravigilance only after awareness was raised by the national authorities. Most narcolepsy reports were received from countries where the signal initially occurred, and were related to Pandemrix® in children/adolescents. Basic information about the patient and the exposure was present in most of the ICSRs. The ICSRs captured by Eudravigilance however, do not collect enough information to assess the diagnostic certainty according to the Brighton Collaboration case definition.

AIMS The aim of this study was to investigate the incidence and reporting rate of drug-induced long-QT syndrome (LQTS) in France [defined by evidence of torsades de pointes (TdP), QT prolongation and exposure to a relevant drug] and to assess feasibility of case collection for drug-induced LQTS. METHODS A retrospective population-based study was carried out in Southwest France in five institutions: three main hospitals, one private clinic and one cardiac emergency unit, searched from 1 January 1999 to 1 January 2005 (population coverage of 614 000). The study population consisted of 861 cases with International Classification of Diseases-10 diagnostic codes for ventricular tachycardia (I147.2), ventricular fibrillation (I149.0) and sudden cardiac death (I146.1) from hospital discharge summaries, supplemented by cases reported to national or regional pharmacovigilance systems, and voluntary reporting by physicians, validated according to internationally defined criteria for drug-induced LQTS. RESULTS Of 861 patients coded with arrhythmias or sudden cardiac death, there were 40 confirmed surviving acquired cases of drug-induced LQTS. We estimated that the incidence of those who survive to reach hospital drug-induced LQTS is approximately 10.9 per million annually in France (95% confidence interval 7.8, 14.8). CONCLUSIONS Many cases of drug-induced LQTS may not survive before they reach hospital, as the reporting rate for drug-induced LQTS identified through the cardiology records and also reported to pharmacovigilance systems for the Midi-Pyrenees area is 3/40 (7.5%). Using the methods outlined it is possible to assemble cases to study genetic susceptibility to drug-induced LQTS and adapt these methods more widely. WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Drug-induced long-QT syndrome (LQTS) is a potentially fatal condition that has led to a number of postmarketing withdrawals in recent years. However, many cases may not survive long enough to reach hospital, and only a small proportion are reported to pharmacovigilance agencies. The extent to which genetic determinants of susceptibility to LQTS are specific to particular drugs, or common to several classes of drug, remains to be determined. WHAT THIS STUDY ADDS We estimated population prevalence of drug-induced LQTS in the Midi-Pyrenees region, southwest France, using five different institutions and assessed feasibility of tracing potential cases (in addition to pharmacovigilance data), using hospital data and rigorous case definition.These methods can be adapted to a wider region, used to augment pharmacovigilance reporting, and offer researchers the opportunity to study genetic susceptibility to drug-induced LQTS.

Metastatic breast cancer affecting the gastrointestinal tract except from the liver is very rare, however, some case reports can be found in literature, autopsy series and several retrospective studies focusing on this issue. In our surgery department we have also documented a case report of metastatic breast cancer manifesting as an obstructive tumor of small intestine.

There is no place for the psychoanalytic case report in the British Journal of Psychiatry.

Wolpert, Lewis; Fonagy, Peter

2009-12-01

As evidence-based mental health and the randomised controlled trial come to dominate the content of major psychiatric journals, the status and clinical utility of single case reports have been increasingly questioned. Arguably, owing to their subjective, anecdotal nature and unsuitability for rigorous scientific testing, this is particularly true of psychoanalytic case studies. Professor Peter Fonagy and Professor Lewis Wolpert debate here whether or not there is a place for such case reports in the British Journal of Psychiatry.

[A case report of infant botulism without a history of honey ingestion].

A 66-day-old female with infant botulism is reported. She was admitted to our hospital with respiratory failure. Laboratory examinations detected botulinal toxin type A in her feces. This was the first case with no history of honey ingestion among the 13 cases of infant botulism reported in Japan. It is possible that other cases, in which honey had not been consumed, remain undiagnosed. Further studies may be needed to clarify the factors necessary to cause infant botulism.

Renal cell carcinomas with sporadic Xp11.2 translocations are uncommon malignancies in children and young adults associated with several different reciprocal translocations involving the TFE3 gene located on chromosome Xp11.2. Placental metastases are extremely rare, with only a handful of cases reported. This study reports the case of a 20-year-old woman with an Xp11.2 translocation renal carcinoma that metastasized to the placenta. This is the first reported case of a renal cell carcinoma metastatic to the placenta and highlights the aggressive behavior of Xp11 translocation renal cell carcinomas.

[The importance of case reports in current pediatric endocrinology and metabolism literature--the analysis of publications indexed in Medline in the years 2004-2009].

Case reports have been used as an educational tool in medicine for a long time, as they are usually the first kind of publications prepared by new authors. In compliance with the rules of the EBM, the evidence-based medicine, a clinical case report (which describes and analyses the manner of diagnosis and treatment) appears at the bottom of the hierarchy of scientific evidences. As a result, medical periodicals limit the publishing of case reports. The aim of the study is to assess how important case reports are in the modern pediatric literature, with special interests in endocrine and metabolic disorders. Searching Medline over the last 5 years (October 2004-October 2009) using key words "case report" was performed. The limitations: "human", age "all children: 0-18 years" and the kind of publication: "case report" were used. For the huge number of publications found, the number and language of the publication was analyzed, and the first 100 free full-text publications in field of endocrine and metabolic disorders in English (from 2007-2009) were rated depending on the kind of case and aim of the publication. A total of 55379 publications classified by Pubmed as case reports were found, including 48805 English, 1592 Spanish, 1538 French, 794 German, 370 Polish, 356 Chinese, 265 Russian and 135 Italian. The published case reports were more often informative than educational in character. The content of the published case reports deals more often with the notification of a new mutation, less frequently presentation of an interesting, rare, unusual case or a new illness or the description of a novel therapy. Less often the published case reports appear to be of educational character or those concerning diagnostic problems or treatment failure. Case reports remain an important contribution to the pediatric literature, mainly fulfilling an essential role in providing information about new medical problems. Medical literature published in Polish is relatively rich in clinical case reports. Publishing a case report in field of endocrinology and metabolism in Pubmed indexed journal is considered reasonable in situations where a new medical condition is being presented (most often a new mutation), a novel therapy has been discovered, the case is interesting or where the publishing of such reports fulfils didactic/educational needs.

Accurately distinguishing non-traumatic intracerebral hemorrhage (ICH) subtypes is important since they may have different risk factors, causal pathways, management, and prognosis. We systematically assessed the inter- and intra-rater reliability of ICH classification systems. We sought all available reliability assessments of anatomical and mechanistic ICH classification systems from electronic databases and personal contacts until October 2014. We assessed included studies' characteristics, reporting quality and potential for bias; summarized reliability with kappa value forest plots; and performed meta-analyses of the proportion of cases classified into each subtype. We included 8 of 2152 studies identified. Inter- and intra-rater reliabilities were substantial to perfect for anatomical and mechanistic systems (inter-rater kappa values: anatomical 0.78-0.97 [six studies, 518 cases], mechanistic 0.89-0.93 [three studies, 510 cases]; intra-rater kappas: anatomical 0.80-1 [three studies, 137 cases], mechanistic 0.92-0.93 [two studies, 368 cases]). Reporting quality varied but no study fulfilled all criteria and none was free from potential bias. All reliability studies were performed with experienced raters in specialist centers. Proportions of ICH subtypes were largely consistent with previous reports suggesting that included studies are appropriately representative. Reliability of existing classification systems appears excellent but is unknown outside specialist centers with experienced raters. Future reliability comparisons should be facilitated by studies following recently published reporting guidelines. © 2016 World Stroke Organization.

[Occupational asthma in Hungary].

PubMed

Endre, László

2015-05-10

Occupational asthma belongs to communicable diseases, which should be reported in Hungary. During a 24-year period between January 1990 and December 2013, 180 occupational asthma cases were reported in Hungary (52 cases between 1990 and 1995, 83 cases between 1996 and 2000, 40 cases between 2001 and 2006, and 5 cases between 2007 and 2013). These data are unusual, because according to the official report of the National Korányi Pulmonology Institute in Budapest, at least 14,000 new adult asthma cases were reported in every year between 2000 and 2012 in Hungary. Also, international data indicate that at least 2% of adult patients with asthma have occupational asthma and at least 50 out of 1 million employees develop occupational asthma in each year. In 2003, 631 new occupational asthma patients were reported in the United Kingdom, but only 7 cases in Hungary. Because it is unlikely that the occupational environment in Hungary is much better than anywhere else in the world, it seems that not all new occupational asthma cases are reported in Hungary. Of the 180 reported cases in Hungary, 55 were bakers or other workers in flour mills. There were 11 metal-workers, 10 health care assistants, 9 workers dealing with textiles (tailors, dressmakers, workers in textile industry) and 9 employees worked upon leather and animal fur. According to international data, the most unsafe profession is the animal keeper in scientific laboratories, but only 4 of them were reported as having occupational asthma during the studied 24 years in Hungary. Interestingly, 3 museologists with newly-diagnosed occupational asthma were reported in 2003, but not such cases occurred before or after that year. In this paper the Hungarian literature of occupational asthma is summarized, followed by a review on the classification, pathomechanism, clinical presentation, predisposing factors, diagnostics and therapeutic aspects of the disease. Epidemiological data of adult asthma in Hungary and data from international studies on the occurrence of occupational asthma are also presented. Finally, the author draws attention to the low reporting activity of occupational asthma in Hungary and discusses the possible causes why this communicable disease is rarely reported.

[Tonsillectomy for PANDAS?].

PubMed

Windfuhr, J P

2016-04-01

Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) is a disease attributed to children with obsessive compulsive or tic disorders associated with streptococcal infections. Because otolaryngologists evaluate a large number of pediatric patients with recurrent streptococcal infections, tonsillectomy (TE) is a common option of therapy. This study was undertaken to evaluate the efficacy of tonsillectomy in patients presenting with a verified PANDAS. A PubMed research was performed using search terms "tonsillectomy" and "PANDAS", "OCD", "compulsive", "pediatric autoimmune", "Chorea" and "Tic" limited by publication date January 1, 1995 to July 31, 2015. Reviews without patients were not included in the review. Nine papers matched our search terms, including 6 case reports with 8 patients and 3 case series. Most case reports were in favor for TE, but this was by far not supported by the findings in the case series. The follow-up ranged form 2-36 months (case reports) and 24-36 months (case series). establishing the diagnosis of PANDAS is complicated by underlying co-morbidities in the field of neurology-psychiatry and the lack of a reliable biomarker. The positive outcome after TE as reported in case studies may be influenced by the postoperative medication and is not supported by the results of large-scale studies. In the light of the considerable postoperative morbidity and unavoidable mortality rate it appears wise to indicate TE only in clinical studies with standardized inclusion criteria. © Georg Thieme Verlag KG Stuttgart · New York.

Chronic myelogenous leukemia (CML) has been reportable to the Pennsylvania Cancer Registry (PCR) since the 1980s, but the completeness of reporting is unknown. This study assessed CML reporting in eastern Pennsylvania where a cluster of another myeloproliferative neoplasm was previously identified. Cases were identified from 2 sources: 1) PCR case reports for residents of Carbon, Luzerne, or Schuylkill County with International Classification of Diseases for Oncology, Third Edition (ICD-O-3) codes 9875 (CML, BCR-ABL+), 9863 (CML, NOS), and 9860 (myeloid leukemia) and date of diagnosis 2001-2009, and 2) review of billing records at hematology practices. Participants were interviewed and their medical records were reviewed by board-certified hematologists. PCR reports included 99 cases coded 9875 or 9863 and 9 cases coded 9860; 2 additional cases were identified by review of billing records. Of the 110 identified cases, 93 were mailed consent forms, 23 consented, and 12 medical records were reviewed. Hematologists confirmed 11 of 12 reviewed cases as CML cases; all 11 confirmed cases were BCR/ABL positive, but only 1 was coded as positive (code 9875). Very few unreported CML cases were identified, suggesting relatively complete reporting to the PCR. Cases reviewed were accurately diagnosed, but ICD-0-3 coding often did not reflect BCR-ABL-positive tests. Cancer registry abstracters should look for these test results and code accordingly.

A systematic review of occupational safety and health business cases.

2009-12-01

Business cases are commonly developed as means to rationalize investment. We systematically reviewed 26 reported cases on occupational safety and health (OSH) interventions to assess if health and productivity arguments make a good business case. To be included in the review, studies had to analyze the costs and benefits, including productivity, of an OSH intervention at the enterprise level. We searched Medline and Embase for studies and used Google search in addition. Two reviewers independently selected studies and extracted data. The intervention profitability was calculated in euros (euro in 2008) as the first year's benefits minus the total intervention costs per worker. The payback period was calculated as the intervention costs divided by the first year's benefits. We found three ex-ante and 23 ex-post cases. In 20 cases, the study design was a before-after comparison without a control group. Generally a 100% reduction of injuries or sickness absence was assumed. In two cases, productivity and quality increases were very large. The main benefit was avoided sick leave. Depreciation or discounting was applied only in a minority of cases. The intervention profitability was negative in seven studies, up to euro 500 per employee in 12 studies and more than euro 500 per employee in seven studies. The payback period was less than half a year for 19 studies. Only a few studies included sensitivity analyses. Few ex-ante business cases for management decisions on OSH are reported. Guidelines for reporting and evaluation are needed. Business cases need more sound assumptions on the effectiveness of interventions and should incorporate greater uncertainty into their design. Ex-post evaluation should be based preferably on study designs that control for trends at a time different from that of the intervention.

Intradiscal injection of triamcinolone hexacetonide for acute, subacute, and chronic sciatica. Results at 3 months an open-prospectus study of 30 cases and review of the literature.

1990-09-01

The authors report an open study of 30 cases of intradiscal injection of triamcinolone hexacetonide in the treatment of sciatica. The patients were monitored at months 1 and 3. The results were judged to be good in 36.6% of the cases, moderate in 36.6% and poor in 26.7% of the cases. Two adverse effects were reported: 1 case of reversible urinary retention and 1 case of deficiency of the dorsiflexor muscles of the foot. The good results reported in previous series were only found in this study when the indications were restricted to certain favourable prognostic factors: duration of sciatica less than 6 months and CAT-scan appearance of discal hernia. This technique has the advantage of being simple, economical and nonallergic. On the basis of the encouraging results of the initial series, this technique should be considered as an interesting therapeutic alternative in sciatica. Larger series and double-blind studies, however, are necessary to confirm the initial results.

Clinical reliability of self-reported data for alcohol, caffeine, and nicotine consumptions is lacking, particularly in adolescents. To compare a self-report questionnaire and hair analysis to assess the reliability and effectiveness of the self-report. A cross-sectional study on 14-15-year-old Italian students (n = 874, 38% males, 62% females) was performed comparing self-reported data to hair analysis. The latter quantified hair concentrations of caffeine, nicotine, cotinine, ethyl glucuronide (EtG), and fatty acid ethyl esters (FAEEs) using mass spectrometry. Concordance between self-report and hair testing ranged from good to poor across substances and levels of use: poor for heavy alcohol intake (EtG: k = 0.36, 20 positive cases by hair analysis, false negative by self-report, 2.3% of total sample; FAEE k = 0.31, 25 positive cases, 2.9% of total sample); fair to poor for active smokers (k = 0.40, 125 positive cases, 14.3% of total sample); and moderate for caffeine (k = 0.57, 56 positive cases, 6.4% of total sample). Epidemiological studies on alcohol, caffeine, and nicotine consumption in adolescents may benefit from the inclusion of toxicological analysis on hair samples to overcome the under-reporting phenomenon of questionnaires and detect more cases of problematic substance use.

Gender bias in clinical case reports: A cross-sectional study of the "big five" medical journals.

PubMed

Allotey, Pascale; Allotey-Reidpath, Caitlin; Reidpath, Daniel D

2017-01-01

Gender bias in medical journals can affect the science and the benefit to patients. It has never been investigated in clinical case reports. The oversight is important because of the role clinical case reports play in hypothesis generation and medical education. We investigated contemporary gender bias in case reports for the highest ranked journals in general and internal medicine. PubMed case reports data from 2011 to 2016 were extracted for the Annals of Internal Medicine, British Medical Journal, the Journal of the American Medical Association, The Lancet, and New England Journal of Medicine. The gender of the patients were identified and a text analysis of the Medical Subject Headings conducted. A total of 2,742 case reports were downloaded and 2,582 (95.6%) reports contributed to the final analysis. A pooled analysis showed a statistically significant gender bias against female case reports (0.45; 95%CI: 0.43-0.47). The Annals of Internal Medicine was the only journal with a point estimate (non significant) in the direction of a bias against male patients. The text analysis identified no substantive difference in the focus of the case reports and no obvious explanation for the bias. Gender bias, previously identified in clinical research and in clinical authorship, extends into the patients presented in clinical case reports. Whether it is driven by authors or editors is not clear, but it likely contributes to and supports an overall male bias of clinical medicine.

Acute respiratory infection case definitions for young children: a systematic review of community-based epidemiologic studies in South Asia.

To explore the variability in childhood acute respiratory infection case definitions for research in low-income settings where there is limited access to laboratory or radiologic investigations. We conducted a systematic review of community-based, longitudinal studies in South Asia published from January 1990 to August 2013, in which childhood acute respiratory infection outcomes were reported. Case definitions were classified by their label (e.g. pneumonia, acute lower respiratory infection) and clinical content 'signatures' (array of clinical features that would be always present, conditionally present or always absent among cases). Case definition heterogeneity was primarily assessed by the number of unique case definitions overall and by label. We also compared case definition-specific acute respiratory infection incidence rates for studies reporting incidence rates for multiple case definitions. In 56 eligible studies, we found 124 acute respiratory infection case definitions. Of 90 case definitions for which clinical content was explicitly defined, 66 (73%) were unique. There was a high degree of content heterogeneity among case definitions with the same label, and some content signatures were assigned multiple labels. Within studies for which incidence rates were reported for multiple case definitions, variation in content was always associated with a change in incidence rate, even when the content differed by a single clinical feature. There has been a wide variability in case definition label and content combinations to define acute upper and lower respiratory infections in children in community-based studies in South Asia over the past two decades. These inconsistencies have important implications for the synthesis and translation of knowledge regarding the prevention and treatment of childhood acute respiratory infection. © 2015 John Wiley & Sons Ltd.

Euthanasia for people with psychiatric disorders or dementia in Belgium: analysis of officially reported cases.

2017-06-23

Euthanasia for people who are not terminally ill, such as those suffering from psychiatric disorders or dementia, is legal in Belgium under strict conditions but remains a controversial practice. As yet, the prevalence of euthanasia for people with psychiatric disorders or dementia has not been studied and little is known about the characteristics of the practice. This study aims to report on the trends in prevalence and number of euthanasia cases with a psychiatric disorder or dementia diagnosis in Belgium and demographic, clinical and decision-making characteristics of these cases. We analysed the anonymous databases of euthanasia cases reported to the Federal Control and Evaluation Committee Euthanasia from the implementation of the euthanasia law in Belgium in 2002 until the end of 2013. The databases we received provided the information on all euthanasia cases as registered by the Committee from the official registration forms. Only those with one or more psychiatric disorders or dementia and no physical disease were included in the analysis. We identified 179 reported euthanasia cases with a psychiatric disorder or dementia as the sole diagnosis. These consisted of mood disorders (N = 83), dementia (N = 62), other psychiatric disorders (N = 22) and mood disorders accompanied by another psychiatric disorder (N = 12). The proportion of euthanasia cases with a psychiatric disorder or dementia diagnosis was 0.5% of all cases reported in the period 2002-2007, increasing from 2008 onwards to 3.0% of all cases reported in 2013. The increase in the absolute number of cases is particularly evident in cases with a mood disorder diagnosis. The majority of cases concerned women (58.1% in dementia to 77.1% in mood disorders). All cases were judged to have met the legal requirements by the Committee. While euthanasia on the grounds of unbearable suffering caused by a psychiatric disorder or dementia remains a comparatively limited practice in Belgium, its prevalence has risen since 2008. If, as this study suggests, people with psychiatric conditions or dementia are increasingly seeking access to euthanasia, the development of practice guidelines is all the more desirable if physicians are to respond adequately to these highly delicate requests.

Malaria is a major health problem in many developing countries including Indonesia. The purpose of this study was to investigate the socio-demographic characteristics and geographic distribution of malaria cases in Bangka District, Bangka-Belitung Island Province, Indonesia. Bangka District is a malaria endemic area of Indonesia. We analyzed the epidemiological data of all reported malaria cases during 2008-2012 in Bangka District. Of the 4,756 malaria-confirmed cases reported during the study period, 3,234 (68. 0%) were among persons aged ≥ 15 years, 1,024 (21.5%) were among persons aged 5-14 years and 498 (10.5%) were among persons aged < 5 years. Malaria cases were primarily located along the sea coast and less frequently in inland. Malaria cases were found not only among the local population but also among migrant workers. The monthly incidence of reported malaria cases in the study population ranged from 0.06 to 1.06 per 1,000 person-months. The cases were mostly due to Plasmodium vivax (57.1%) followed by Plasmodiumfalciparum (40.2%). Plasmodiumfalciparum was more common among migrant workers while Plasmodium vivax was more common among the local population (Odds ratio 1.2; p = 0.03). The main transmission vector found in the coastal area was Anopheles sundaicus. An. letifer and An. barbirostris were found inland. We identified "malaria hot-spots" in the study area using a Geographic Information System. The results of this study will contribute to the malaria control program.

Are dietary reports in a case-control study on thyroid cancer biased by risk perception of Chernobyl fallout?

In retrospective case-control studies performed following nuclear tests or nuclear accidents, individual thyroid radiation dose reconstructions are based on fallout and meteorological data from the residential area, demographic characteristics, and lifestyle as well as dietary information. Collecting the latter is a controversial step, as dietary declarations may be affected by the subjects' beliefs about their risk behavior. This report analyses the potential for such bias in a case-control study performed in eastern France. The study included 765 cases of differentiated thyroid carcinoma matched with 831 controls. Risk perceptions and beliefs of cases and controls were compared using Chi 2 tests and differences in dietary reports were analyzed using a two-way ANOVA. In general, atmospheric pollution and living near a nuclear power plant were the two major risks that may influence thyroid cancer occurrence cited by cases and controls. When focusing in particular on the consequences of the Chernobyl accident, cases were more likely to think that the consequences were responsible for thyroid cancer occurrence than controls. Vegetable consumption during the two months after the Chernobyl accident was correlated with the status of subjects, but not to their beliefs. Conversely, consumption of fresh dairy products was not correlated with the status or beliefs of subjects. We found no evidence of systematic bias in dietary reports according to the status or beliefs held by subjects about the link between thyroid cancer occurrence and Chernobyl fallout. As such, these dietary reports may be used in further studies involving individual dosimetric reconstructions. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Why mistreatment of medical students is not reported in clinical settings: perspectives of trainees.

PubMed

Mistreatment of medical students is a major source of stress for them. Studies indicate a high incidence of such mistreatment, especially in clinical settings. In most cases, students who have been mistreated do not report it to the authorities. This study investigated factors related to the failure to report mistreatment. This was a cross-sectional study carried out in Kerman Medical School, Iran. All students in the internship and clerkship stages, as well as residents, were selected through the census method. Experiences of mistreatment and the reasons for not reporting them were evaluated using a questionnaire. The data were analysed with SPSS 19. Ninety-three per cent of the participants experienced mistreatment, but less than half of them reported it. Residents and interns reported emotional and academic mistreatment, respectively, more than other groups. The most common reason for not reporting mistreatment was that the students did not think reporting would accomplish anything. Our study showed that the experience of mistreatment in the clinical setting is common, but the cases reported to the authorities are far fewer than the actual number of cases. Educational systems should make extensive efforts to detect and prevent mistreatment to improve the teaching-learning environment.

Music therapy in the treatment of multiple sclerosis: a comprehensive literature review.

PubMed

Ostermann, Thomas; Schmid, Wolfgang

2006-04-01

Coping with multiple sclerosis symptoms still remains a challenge for each patient suffering from this chronic inflammatory disease. Therefore, patients often turn to using complementary and alternative medicine (CAM). In this review, the authors aimed to investigate the current state of literature of music therapy in the treatment of multiple sclerosis (MS). Medline, PubMed, Embase, AMED, CAMbase and the Music Therapy World Journal Index were searched for the terms MS and 'music therapy'. In addition, an internet search using Google Scholar was performed. The authors found seven case-reports/series and seven studies on music therapy for MS-patients. Both the case reports and studies presented here are pioneer work. Most of the studies are naturally predominated by the use of qualitative and uncontrolled research designs. Nevertheless, the results of the studies as well as the case reports demonstrate patients' improvement in the domains of self-acceptance, anxiety and depression. The results of the studies as well as the case reports define a sufficient basis for further music therapeutical work as they show a variety of psychosocial and emotional benefits for MS patients.

To assess reported cases of bisphosphonate-related osteonecrosis of the jaw (BONJ) to Medicines Agencies (MAs) in four Nordic countries and to compare the Norwegian MA data with BONJ cases retrieved through an e-mail survey to Oral and Maxillofacial Surgeons (OMS) in Norway. BONJ cases reported to the national MAs in each country from January 1st 2003 to September 30th 2010 were collected. An e-mail survey was sent to all active members of the Norwegian Association of Oral and Maxillofacial Surgeons (n = 54) included questions on total BONJ cases seen in practice and route of drug administration during January 1st 2003 to December 31st 2009. In total, 253 BONJ cases were reported to the MAs; 39 in Denmark, 44 in Finland, 51 in Norway and 119 in Sweden. These figures result in cumulative incidences (multiplied by 100,000) of 0.7, 0.8, 1.1 and 1.3, respectively. Intravenous administration was reported in 169 of the cases. The e-mail survey resulted in 35 responses reporting 214 BONJ cases, 4-times more cases than reported to the MA. Cumulative incidence of cases reported in this study differs to some degree in the four Nordic countries (Denmark < Finland < Norway < Sweden). In Norway, almost the same number of BONJ cases were reported through the questionnaire by OMS as in all four countries together (214 by OMSs vs 254 to MAs) and included a high number after per oral administration. The present results indicate a notable under-reporting in Norway and most likely in other Nordic countries.

The purpose of this study was to investigate the utility and clinical impact of second-opinion interpretations of outside neuroimaging studies by oncologic neuroradiologists at a National Cancer Institute-designated cancer center. We performed a retrospective analysis of initial outside and second-opinion radiology reports from 300 computed tomography and magnetic resonance imaging studies and identified cases with discrepancies between the two reports. An adult neuro-oncologist, pediatric neuro-oncologist, and head and neck surgeon reviewed each pair of discrepant reports based on their area of expertise, patient age, and the type of study performed. The clinicians were blinded to the origin of each report and recorded whether the differences in the reports would have led to a change in patient management and/or disease staging. Histopathologic analysis, clinical assessment, and/or minimum 3-month imaging follow-up served as the reference standards to establish which of the 2 reports was correct. Among the 283 cases that met our study criteria, there were 55 neuroimaging studies with disagreements (19%) between the initial outside report and second-opinion interpretation. Patient management and/or disease stage would have been altered in 42 of 283 cases (15%) based on report differences as determined by the 2 neuro-oncologists and the surgeon participating in the study. Sufficient follow-up was available in 35 of 42 cases (83%). The second-opinion interpretation was correct 100% of the time (35/35). Second-opinion interpretations of neuroimaging studies by subspecialized oncologic neuroradiologists provide added value by reducing error and optimizing the care of cancer patients.

Changes to Hospital Inpatient Volume After Newspaper Reporting of Medical Errors.

PubMed

Fukuda, Haruhisa

2017-06-30

The aim of this study was to investigate the influence of medical error case reporting by national newspapers on inpatient volume at acute care hospitals. A case-control study was conducted using the article databases of 3 major Japanese newspapers with nationwide circulation between fiscal years 2012 and 2013. Data on inpatient volume at acute care hospitals were obtained from a Japanese government survey between fiscal years 2011 and 2014. Panel data were constructed and analyzed using a difference-in-differences design. Acute care hospitals in Japan. Hospitals named in articles that included the terms "medical error" and "hospital" were designated case hospitals, which were matched with control hospitals using corresponding locations, nurse-to-patient ratios, and bed numbers. Medical error case reporting in newspapers. Changes to hospital inpatient volume after error reports. The sample comprised 40 case hospitals and 40 control hospitals. Difference-in-differences analyses indicated that newspaper reporting of medical errors was not significantly associated (P = 0.122) with overall inpatient volume. Medical error case reporting by newspapers showed no influence on inpatient volume. Hospitals therefore have little incentive to respond adequately and proactively to medical errors. There may be a need for government intervention to improve the posterror response and encourage better health care safety.

To analyze the characteristics of tuberculosis outbreaks declared under vigilance programs in Catalonia. Descriptive study of outbreaks from 1998 through 2002 for which reports were available. An outbreak was defined as 3 or more associated cases appearing within a year. For 2 health care regions, outbreaks for which there were full surveillance reports with contact tracing were compared to outbreaks identified but which had not been fully reported. Twenty-seven outbreaks were analyzed. Nineteen (70%) occurred within families. A total of 22 outbreaks were declared upon identification of the true index case and 5 upon detection of secondary cases. The mean annual incidence of outbreaks was 0.40/100,100 inhabitants. Most cases were in males 16 to 40 years of age and involved cavitary lesions and a clinically significant diagnostic delay. Twenty-seven outbreaks caused 69 secondary cases. A longer diagnostic delay was seen to correspond to a larger number of secondary cases (P=.08). In the 2 health care regions analyzed, full surveillance reports with contact tracing were issued for 2 of the 14 outbreaks detected (14.4%). Tuberculosis outbreaks are common but investigative follow-up is scarce. The size of the outbreak is related to the length of diagnostic delay. Rapid diagnosis, contact tracing, and the issuance of a public health report should be priorities in all outbreaks detected.

The present study used data from an ongoing longitudinal study of the effects of maltreatment on adolescent development to (1) describe rates of maltreatment experiences obtained from retrospective self-report versus case record review for adolescents with child welfare-documented maltreatment histories, (2) examine self-reported versus child welfare-identified maltreatment in relation to mental health and risk behavior outcomes by maltreatment type, and (3) examine the association between the number of different types of maltreatment and mental health and risk behavior outcomes. Maltreatment was coded from case records using the Maltreatment Case Record Abstraction Instrument (MCRAI) and participants were asked at mean age = 18.49 about childhood maltreatment experiences using the Comprehensive Trauma Interview (CTI). Results showed that an average of 48% of maltreatment found by the MCRAI for each type of maltreatment were unique cases not captured by the CTI, whereas an average of 40% self-reported maltreatment (CTI) was not indicated by the MCRAI. Analyses with outcomes showed generally, self-reported maltreatment, regardless of concordance with MCRAI, was related to the poorest outcomes. The difference in associations with the outcomes indicates both self-report and case record review data may have utility depending on the outcomes being assessed.

The authors report two cases of extra skeletal Ewing's sarcoma. The first case concerns a 26 years old woman presenting a tumor at the level of the sacrum area, locally recurrent, metastazing to the lungs and the lumbar column, despite of radiotherapy and chemotherapy and leading to death after a course of 18 months. The second one is that of a 30 years old man bearing a tumor of the shoulder area probably already metastazed to bones, rapidly recurrent and metastazing to the lungs and cause of death after 9 months in spite of intensive therapy. About these 2 observations a review of the literature of the cases of extra skeletal Ewing's sarcoma is done. Whatever nosologic discussion it seems that Ewing's sarcoma may present essentially as a tumor of soft tissues. An ultrastructural study has been performed in the second case. The findings are similar to those reported in Ewing's sarcoma.

Objectives To analyze the trend of dextromethorphan abuse in California and to compare these findings with national trends. Design A 6-year retrospective review. Setting California Poison Control System (CPCS), American Association of Poison Control Centers (AAPCC), and Drug Abuse Warning Network (DAWN) databases from January 1, 1999, to December 31, 2004. Participants All dextromethorphan abuse cases reported to the CPCS, AAPCC, and DAWN. The main exposures of dextromethorphan abuse cases included date of exposure, age, acute vs long-term use, coingestants, product formulation, and clinical outcome. Main Outcome Measure The annual proportion of dextromethorphan abuse cases among all exposures reported to the CPCS, AAPCC, and DAWN databases. Results A total of 1382 CPCS cases were included in the study. A 10-fold increase in CPCS dextromethorphan abuse cases from 1999 (0.23 cases per 1000 calls) to 2004 (2.15 cases per 1000 calls) (odds ratio, 1.48; 95% confidence interval, 1.43–1.54) was identified. Of all CPCS dextromethorphan abuse cases, 74.5% were aged 9 to 17 years; the frequency of cases among this age group increased more than 15-fold during the study (from 0.11 to 1.68 cases per 1000 calls). Similar trends were seen in the AAPCC and DAWN databases. The highest frequency of dextromethorphan abuse occurred among adolescents aged 15 and 16 years. The most commonly abused product was Coricidin HBP Cough & Cold Tablets. Conclusions Our study revealed an increasing trend of dextromethorphan abuse cases reported to the CPCS that is paralleled nationally as reported to the AAPCC and DAWN. This increase was most evident in the adolescent population. PMID:17146018

Differential reporting of mixed DNA profiles and its impact on jurists' evaluation of evidence. An international analysis.

While DNA analysis is considered by many the gold standard in forensic science, there is ample room for variation in interpretation and reporting. This seems especially the case when working with (complex) mixed DNA profiles. Two consecutive studies on differential DNA reporting were conducted. In Study 1, we first examined type and magnitude of differences when forensic DNA experts across institutes and jurisdictions are handed an identical forensic case with mixed profiles. In Study 2, we explore the impact of the observed differential reporting on jurists' evaluation of the DNA evidence. 19 DNA expert reports from forensic institutes across Western jurisdictions were obtained. Differences between the reports were many and include extensiveness of the reports, explanations of technical issues, use of explanatory appendices, level of reporting, use of context information, and, most markedly, type and substantive content of the conclusions. In Study 2, a group of criminal law students judged a selection of these reports in a quasi experimental study design. Findings show that these differing reports have quite different evidentiary value for jurists, depending on which expert authored the report. It is argued that the impact of differential reporting on jurists' evaluation was so fundamental and substantive that it is seems reasonable to claim that in an actual court case it could make the difference between acquittal and conviction.

Structure-Specific Movement Patterns in Patients With Chronic Low Back Dysfunction Using Lumbar Combined Movement Examination.

PubMed

Monie, Aubrey P; Price, Roger I; Lind, Christopher R P; Singer, Kevin P

2017-06-01

A test-retest cohort study was conducted to assess the use of a novel computer-aided, combined movement examination (CME) to measure change in low back movement after pain management intervention in 17 cases of lumbar spondylosis. Additionally we desired to use a CME normal reference range (NRR) to compare and contrast movement patterns identified from 3 specific structural pathologic conditions: intervertebral disc, facet joint, and nerve root compression. Computer-aided CME was used before and after intervention, in a cohort study design, to record lumbar range of movement along with pain, disability, and health self-report questionnaires in 17 participants who received image-guided facet, epidural, and/or rhizotomy intervention. In the majority of cases, CME was reassessed after injection together with 2 serial self-reports after an average of 2 and 14 weeks. A minimal clinically important difference of 30% was used to interpret meaningful change in self-reports. A CME NRR (n = 159) was used for comparison with the 17 cases. Post hoc observation included subgrouping cases into 3 discrete pathologic conditions, intervertebral disc, facet dysfunction, and nerve root compression, in order to report intergroup differences in CME movement. Seven of the 17 participants stated that a "combined" movement was their most painful CME direction. Self-report outcome data indicated that 4 participants experienced significant improvement in health survey, 5 improved by ≥30% on low back function, and 8 reported that low back pain was more bothersome than stiffness, 6 of whom achieved the minimal clinically important difference for self-reported pain. Subgrouping of cases into structure-specific groups provided insight to different CME movement patterns. The use of CME assists in identifying atypical lumbar movement relative to an age and sex NRR. Data from this study, exemplified by representative case studies, provide preliminary evidence for distinct intervertebral disc, facet joint, and nerve root compression CME movement patterns in cases of chronic lumbar spondylosis.

Objective Studies to determine the incidence and prevalence of amyotrophic lateral sclerosis (ALS) in defined geographic areas in the USA are needed. The Florida Department of Health received funding from the federal Agency for Toxic Substances and Disease Registry to implement a state-wide ALS Surveillance Project. The objectives of the project were to describe the demographic characteristics of ALS cases and to calculate the incidence and prevalence of ALS in Florida. Setting/participants All neurologists were asked to submit case reports for persons with ALS diagnosed and/or under their care during 1 January 2009 through 31 December 2011. A medical record verification form and an electromyogram (EMG) report were requested for a sample of cases and reviewed by an independent consulting neurologist to confirm ALS diagnosis. Death data were used to aid with case report collection. Primary and secondary outcome measures Demographics, relevant history and clinical characteristics, El Escorial classifications, time from symptom onset to diagnosis, crude annual incidence rates and 2009 period prevalence are presented. Results The 1450 reported ALS cases were more likely to be older, male, white and non-Hispanic. Slightly more than 4% of cases were reported as also having dementia, and 4.8% were reported to have an immediate family member diagnosed with ALS. Incidence rates ranged from 1.7 to 1.9 per 100 000 person-years during the project period and the 2009 period prevalence was 4.0 per 100 000 persons. Conclusions Project findings are generally consistent with findings of population-based studies in Europe, as well as geographically limited studies in the USA. Our findings add to the growing body of epidemiological literature about ALS in the USA. Future epidemiological studies in the USA should focus on identifying cases from minority groups and those that may have limited access to healthcare, and should consider conducting capture–recapture analysis to assess case ascertainment.

Background Ukraine developed Europe's most severe HIV epidemic due to widespread transmission among persons who inject drugs (PWID). Since 2004, prevention has focused on key populations; antiretroviral therapy (ART) coverage has increased. Recent data show increases in reported HIV cases through 2011, especially attributed to sexual transmission, but also signs of potential epidemic slowing. We conducted a data triangulation exercise to better analyze available data and inform program implementation. Methods and Findings We reviewed data for 2005 to 2012 from multiple sources, primarily national HIV case reporting and integrated biobehavioral surveillance (IBBS) studies among key populations. Annually reported HIV cases increased at a progressively slower rate through 2011 with recent increases only among older, more immunosuppressed individuals; cases decreased 2.7% in 2012. Among women <25 years of age, cases attributed to heterosexual transmission and HIV prevalence in antenatal screening declined after 2008. Reported cases among young PWID declined by three-fourths. In 2011, integrated biobehavioral surveillance demonstrated decreased HIV prevalence among young members of key populations compared with 2009. HIV infection among female sex workers (FSW) remains strongly associated with a personal history of injecting drug use (IDU). Conclusions This analysis suggests that Ukraine's HIV epidemic has slowed, with decreasing reported cases and older cases predominating among those diagnosed. Recent decreases in cases and in prevalence support decreased incidence among young PWID and women. Trends among heterosexual men and men who have sex with men (MSM) are less clear; further study and enhanced MSM prevention are needed. FSW appear to have stable prevalence with risk strongly associated with IDU. Current trends suggest the Ukrainian epidemic can be contained with enhanced prevention among key populations and increased treatment access. PMID:25251080

Schematic representation of case study research designs.

Rosenberg, John P; Yates, Patsy M

2007-11-01

The paper is a report of a study to demonstrate how the use of schematics can provide procedural clarity and promote rigour in the conduct of case study research. Case study research is a methodologically flexible approach to research design that focuses on a particular case - whether an individual, a collective or a phenomenon of interest. It is known as the 'study of the particular' for its thorough investigation of particular, real-life situations and is gaining increased attention in nursing and social research. However, the methodological flexibility it offers can leave the novice researcher uncertain of suitable procedural steps required to ensure methodological rigour. This article provides a real example of a case study research design that utilizes schematic representation drawn from a doctoral study of the integration of health promotion principles and practices into a palliative care organization. The issues discussed are: (1) the definition and application of case study research design; (2) the application of schematics in research; (3) the procedural steps and their contribution to the maintenance of rigour; and (4) the benefits and risks of schematics in case study research. The inclusion of visual representations of design with accompanying explanatory text is recommended in reporting case study research methods.

There has been a noted increase in the diagnosis and reporting of sporting hip injuries and conditions in the medical literature but reporting at the minor hockey level is unknown. The purpose of this study is to investigate the trend of reporting hip injuries in amateur ice hockey players in Canada with a focus on injury type and mechanism. A retrospective review of the Hockey Canada insurance database was performed and data on ice hockey hip injuries reported between January 2005 and June 2011 were collected. The study population included all male hockey players from Peewee (aged 11-12 years) to Senior (aged 20+ years) participating in amateur level competition sanctioned by Hockey Canada. Reported cases of ice hockey hip injuries were analyzed according to age, mechanism of injury, and injury subtype. Annual injury reporting rates were determined and using a linear regression analysis trended to determine the change in ice hockey hip injury reporting rate over time. One hundred and six cases of ice hockey-related hip injuries were reported in total. The majority of injuries (75.5%) occurred in players aged 15-20 years playing at the Junior level. Most injuries were caused by a noncontact mechanism (40.6%) and strains were the most common subtype (50.0%). From 2005 to 2010, the number of reported hip injuries increased by 5.31 cases per year and the rate of reported hip injury per 1,000 registered players increased by 0.02 cases annually. Reporting of hip injuries in amateur ice hockey players is increasing. A more accurate injury reporting system is critical for future epidemiologic studies to accurately document the rate and mechanism of hip injury in amateur ice hockey players.

Childhood herpes zoster: a clustering of ten cases.

PubMed

Prabhu, Smitha; Sripathi, H; Gupta, Sanjeev; Prabhu, Mukyaprana

2009-01-01

Herpes zoster occurs due to reactivation of the latent varicella zoster virus and is usually a disease of the elderly. Childhood herpes zoster is believed to be rare, though recent studies suggest increasing incidence in children. Here we report ten cases of childhood herpes zoster, seven of which occurred within a short span of six months, at a tertiary care level hospital in Pokhara, Nepal. Only three of the ten children reported previous history of varicella infection and none was immunized against varicella. Though childhood herpes zoster accounted for less than 1% of the total zoster cases in the past, recent reports show an increase in the number of cases in apparently healthy children. So far, no studies have been done linking childhood herpes zoster with HIV, though there are many studies linking it with other immunocompromised conditions.

Dengue fever has emerged as a major public health problem globally in the past three decades. A 13-year national surveillance data analysis was done to describe the epidemiology and its trend of dengue disease in Oman reported between 2001 and 2013. Laboratory-confirmed dengue virus infections reported were studied retrospectively during the study period. A total of 64 laboratory confirmed cases were reported. All the patients contracted the disease during their visit to South-East Asian countries, hence classified as imported cases. The majority of the cases were reported in the year 2012 (23.4%). The most important clinical characteristics were fever (90.6%), myalgia (35.9%) and rash/petechial rash (20.3%). Thrombocytopenia was seen in 31.2% of the study subjects. The mortality was nearly 4.6% and all other patients made a full recovery. The most effective measure for travellers is taking precautions to avoid mosquito bites. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

To report three cases of patients with Systemic Sclerosis (SSc) and retrocochlear impairments. This is a case report of three individuals with SSc and retrocochlear impairments assisted at a rheumatology outpatient clinic. All individuals underwent Brainstem Auditory Evoked Potential (BAEP) and, when necessary, audiometry. All three individuals presented sensorineural hearing loss. Although no retrocochlear impairment was identified in the basic audiologic evaluation, the BAEP results were altered. Retrocochlear impairments were present in the individuals under study, both in the absolute latencies and interpeak interval, thereby demanding the attention of rheumatologists and speech-language pathologists to such changes during the monitoring of SSc patients. The results also show a need for epidemiological studies on the theme.

We classified discharges as 1) "coded sepsis discharges"-a diagnosis code for severe sepsis or septic shock and 2) "possible sepsis discharges," using Dombrovskiy and Angus criteria. Of 111,816 sepsis cases reported to the New York State Department of Health Sepsis Clinical Database, 105,722 (94.5%) were matched to discharge records in Statewide Planning and Research Cooperative System. The percentage of coded sepsis discharges reported increased from 67.5% in the first quarter to 81.3% in the final quarter of the study period (mean, 77.7%). Accounting for unmatched cases, as many as 82.7% of coded sepsis discharges were potentially reported, whereas at least 17.3% were unreported. Compared with unreported discharges, reported discharges had higher rates of acute organ dysfunction (e.g., cardiovascular dysfunction 63.0% vs 51.8%; p < 0.001) and higher in-hospital mortality (30.2% vs 26.1%; p < 0.001). Hospital characteristics (e.g., number of beds, teaching status, volume of sepsis cases) were similar between hospitals with a higher versus lower percent of discharges reported, p values greater than 0.05 for all. Hospitals' percent of discharges reported was not correlated with risk-adjusted mortality of their submitted cases (Pearson correlation coefficient 0.11; p = 0.17). Approximately four of five discharges with a diagnosis code of severe sepsis or septic shock in the Statewide Planning and Research Cooperative System data were reported in the New York State Department of Health Sepsis Clinical Database. Incomplete reporting appears to be driven more by underrecognition than attempts to game the system, with minimal bias to risk-adjusted hospital performance measurement.

Introduction The increasing incidences of violence against doctors in their workplaces are an important reason for stress among these healthcare workers. Many incidences of workplace violence against doctors have been reported in the past and are also being continuously reported from different parts of the country as well as the world. Aim To determine the prevalence of workplace violence among doctors and to study the associated risk factors in a tertiary care hospital of Delhi, India. Material and Methods A cross-sectional study was conducted using a self-administered semi-structured questionnaire. The contents were: data related to the workplace, incidences at work, violence prevention policy of the institution, reporting of incidences and follow-up, education and training for violence management. A total of 151 doctors participated in the study. Results Total participants in the study were 151. The mean age of study participants was 26.73±4.24 years. Almost half (47.02%; 44.56% of males and 50.84% of females) of the doctors reported having an experience of violence during work hours in past 12 months. Among the cases, 39.4% were reported from Department of Obstetrics and Gynaecology while Surgery, Medicine and other departments reported 29.6%, 26.8% and 4.2% respectively. Patients or their relatives were perpetrators in most of the cases. Maximum (87.3%) of the reported cases were of verbal violence while 8.6% of the cases were of physical violence. Younger doctors with less work experience were more prone to physical violence. Regarding the time of violence, 35.1% of such cases occurred during afternoon while 30.1% of them took place at night. Conclusion A large number of doctors had experienced violence in past 12 months in a tertiary care hospital of South Delhi, India. Verbal violence came out to be most common form of violence experienced by the doctors. Afternoon or night hours were the timings when majority of such cases were reported. PMID:28050406

Objectives To know the prevalence of leptospirosis cases reported in private clinics among fever cases in Villupuram District, Tamil Nadu, India to know its real magnitude of the problem and to diagnose Leptospirosis among fever cases from differential diagnosis. Methods 1502 Blood serum samples collected from three urban towns namely Kallakurichi (Latitude: 11° 73′ N; Longitude: 78° 97′ E), Villupuram (Latitude: 11° 75′ N; Longitude: 79° 92′ E) and Thindivanam (Latitude: 12° 25′ N; Longitude: 79° 65′ E) in fifteen clinics based on case definition of leptospirosis delineated by the National Vector Borne Disease Control Programme (NVBDCP), Government of India. Samples were tested in the laboratory of the Zonal Entomological Team (ZET), Cuddalore with Macroscopic Slide Agglutination Test (MSAT) and Ig-M ELISA. Result There were 65 positive cases detected from 1502 blood serum samples in both MSAT and Ig-M ELISA. It could be known that there was 4% cases contributed from private clinics among fever cases. From this study, further it was known that all age groups of people affected irrespective of sexes based on their living condition associated with the environment prevailed of the disease. Conclusion From this study, it was quantified that 4% of cases reported in private clinics among fever cases and its findings ascertained both the importance of differential diagnosis as well as reports that should be included to the Government for knowing its real magnitude for planning.

Neurological involvement is one of the most important clinical manifestations of syphilis and neurological disease occurs in both early and late syphilis. The impact of HIV co-infection on clinical neurosyphilis remains unclear. The highest prevalence of both syphilis and HIV is in Africa. Therefore it might be expected that neurosyphilis would be an important and not uncommon manifestation of syphilis in Africa and frequently occur in association with HIV co-infection; yet few data are available on neurosyphilis in Africa. The aim of this study is to review data on neurosyphilis in Africa since the onset of the HIV epidemic. We searched the literature for references on neurosyphilis in Africa for studies published between the 1st of January 1990 and 15th February 2017. We included case reports, case series, and retrospective and prospective cohort and case-control studies. We did not limit inclusion based on the diagnostic criteria used for neurosyphilis. For retrospective and prospective cohorts, we calculated the proportion of study participants who were diagnosed with neurosyphilis according to the individual study criteria. Depending on the study, we assessed the proportion of patients with syphilis found to have neurosyphilis, and the proportion of patients with neurological syndromes who had neurosyphilis. Due to heterogeneity of data no formal pooling of the data or meta-analysis was undertaken. Amongst patients presenting with a neurological syndrome, three studies of patients with meningitis were identified; neurosyphilis was consistently reported to cause approximately 3% of all cases. Three studies on stroke reported mixed findings but were limited due to the small number of patients undergoing CSF examination, whilst neurosyphilis continued to be reported as a common cause of dementia in studies from North Africa. Ten studies reported on cases of neurosyphilis amongst patients known to have syphilis. Studies from both North and Southern Africa continue to report cases of late stage syphilis, including tabes dorsalis and neurosyphilis, in association with ocular disease. This is the first systematic review of the literature on neurosyphilis in Africa since the beginning of the HIV epidemic. Neurosyphilis continues to be reported as a manifestation of both early and late syphilis, but the methodological quality of the majority of the included studies was poor. Future well-designed prospective studies are needed to better delineate the incidence and clinical spectrum of neurosyphilis in Africa and to better define interactions with HIV in this setting.

Objective To estimate the reported incidence of occupational hypersensitivity pneumonitis (OHP) in the UK and to consider whether the pattern of attributed causation has changed over time. Methods All cases of OHP reported to the SWORD scheme between January 1996 and December 2015 were classified into 1 of 10 categories of the suspected agent. Cases were grouped into four 5-year time periods to examine any changing pattern in incidence or suspected causation. For each time period, the annual incidence was calculated using the estimated number of reported cases and the working population of the UK. Results Between 1996 and 2015, there were 202 actual cases of OHP reported to SWORD, equating to an estimated 818 cases, when adjusting for the sampling ratio. Over this period, the annual UK incidence was 1.4 per million workers. The mean (SD) age of reported cases was 52 (13) years, and cases were four-times more likely to be men than women. Over the study period, there was a fall in the proportion of cases reported to be due to agricultural exposures (44–12%), and an increase in cases due to metalworking fluids (MWFs, 2–45%). Conclusions Over the last 20 years, the incidence of OHP in the UK has been ∼1–2 cases per million workers per year. Working with water-based MWFs is now the most commonly suspected causative exposure for OHP cases reported to the SWORD scheme in the UK. PMID:27919062

Objectives The objective of this study was to describe factors that influence the ability of state Medicaid agencies to report the Centers for Medicare & Medicaid Services' (CMS) core set of children's health care quality measures (Child Core Set). Methods We conducted a multiple-case study of four high-performing states participating in the Children's Health Insurance Program Reauthorization Act (CHIPRA) Quality Demonstration Grant Program: Illinois, Maine, Pennsylvania, and Oregon. Cases were purposively selected for their diverse measurement approaches and used data from 2010 to 2015, including 154 interviews, semiannual grant progress reports, and annual public reports on Child Core Set measures. We followed Yin's multiple-case study methodology to describe how and why each state increased the number of measures reported to CMS. Results All four states increased the number of Child Core Set measures reported to CMS during the grant period. Each took a different approach to reporting, depending on the available technical, organizational, and behavioral inputs in the state. Reporting capacity was influenced by a state's Medicaid data availability, ability to link to other state data systems, past experience with quality measurement, staff time and technical expertise, and demand for the measures. These factors were enhanced by CHIPRA Quality Demonstration grant funding and other federal capacity building activities, as hypothesized in our conceptual framework. These and other states have made progress reporting the Child Core Set since 2010. Conclusion With financial support and investment in state data systems and organizational factors, states can overcome challenges to reporting most of the Child Core Set measures.

Forensic reports on traumatic peripheral nerve injuries include dysfunction degrees of extremities, which are arranged according to the Turkish Penalty Code. The aim of this study is to discuss the role and importance of electromyography while preparing forensic reports in the cases of traumatic peripheral nerve injuries and the usefulness of scoring systems. A modified global scale, recommended by Mondelli et al., was used to assess the electrophysiological impairment of each peripheral nerve. Forensic reports of 106 patients, reported between 2002 and 2004, were evaluated. Thirty-four percent of the cases were reported as "total loss of function," 41.5% were reported as "functional disability," and there were no dysfunctions in the other cases in forensic reports that were prepared based on Council of Social Insurance Regulations of Health Processes and Guide prepared by the Council of Forensic Medicine and profession associations of forensic medicine. When we rearranged these forensic reports based on the electrophysiological severity scale (ESS), it was clearly found that all of the score 2 cases and 86.7% of the score 3 cases corresponded to "functional disability" and 91.4% of the score 4 cases correspond to "total loss of function." We found a significant correlation between the ESS and functional evaluation in peripheral nerve injury cases. Evaluation of functional disabilities in peripheral nerve injuries with the ESS represents a standardized and objective method used for forensic reports.

The International Circumpolar Surveillance (ICS) project is a population-based surveillance network. Since 2000, Canada has participated in the ICS Invasive Bacterial Disease Working Group's surveillance of invasive disease due to Haemophilus influenzae (Hi). A standardized case report form containing demographic and clinical information was completed for all reported Hi cases in the study regions. Isolates were sent to a reference laboratory for confirmation and serotyping. Analysis was conducted on all Hi serotype a (Hia) cases reported from 2000 to 2010. The northern Canadian population was estimated using Statistics Canada information. Of the 130 Hi cases reported from 2000 to 2010, 72 (56% of cases with serotype information) were due to Hia. The number of Hia cases reported each year ranged from 2 in 2008 to 13 in 2010. The average Hia incidence over the 11 years was 4.6 cases per 100,000 population per year. The majority of Hia occurred in infants less than 2 years of age (73% of cases). This age group had an average annual incidence of 87.5 cases per 100,000 population. Among cases for which ethnicity was indicated, 91% of Hia cases reported Aboriginal status with the average incidence being 6.9 cases per 100,000 population per year. The most common clinical presentation was meningitis (reported in 37% of cases), followed by bacteraemia (34%) and pneumonia (27%). More than 90% of cases were hospitalized, and there were 4 deaths, resulting in a case fatality ratio of 5.6%. In the last decade, Hia has become an important cause of morbidity and mortality in the Canadian North. More detailed surveillance information from a national perspective is needed. Further work on vaccine development should be encouraged.

Lost in laterality: interpreting ''preferred side of the head during mobile phone use and risk of brain tumour'' associations.

PubMed

Schüz, Joachim

2009-08-01

Due to the highly localized exposure from mobile phones, the preferred side of the head during their use is important information when investigating a possible link with brain tumour risk, but at the same time, error and bias hamper the assessment of this information in case-control studies. Current studies provide evidence of reporting bias insofar as cases appear to over-report the side of the head where the tumour occurred as the one that they preferred in the past when using mobile phones. More refined methods of analysis among only cases or prospective studies with an assessment of the laterality of mobile phone use before the diagnosis of disease are needed to evaluate whether associations seen in some studies are entirely due to reporting bias or a mixture of reporting bias and a causal effect.

Serial killers have always fascinated society. A serial killer is typically defined as a perpetrator who murders three or more people over a period of time. Most reported cases of serial killers come from the United States and Canada. In India, there are few reported cases. We present, to the best of our knowledge, the first Indian case in the literature. The present case is of a 28-year-old man, Surinder Koli. The Department of Forensic Medicine & Toxicology, All India Institute of Medical Sciences, New Delphi handled the forensic study. We present a most unique psychological investigation into the mind of a serial killer.

We describe here an approach for estimating the probability that study subjects were exposed to metalworking fluids (MWFs) in a population-based case-control study of bladder cancer. Study subject reports on the frequency of machining and use of specific MWFs (straight, soluble, and synthetic/semi-synthetic) were used to estimate exposure probability when available. Those reports also were used to develop estimates for job groups, which were then applied to jobs without MWF reports. Estimates using both cases and controls and controls only were developed. The prevalence of machining varied substantially across job groups (10-90%), with the greatest percentage of jobs that machined being reported by machinists and tool and die workers. Reports of straight and soluble MWF use were fairly consistent across job groups (generally, 50-70%). Synthetic MWF use was lower (13-45%). There was little difference in reports by cases and controls vs. controls only. Approximately, 1% of the entire study population was assessed as definitely exposed to straight or soluble fluids in contrast to 0.2% definitely exposed to synthetic/semi-synthetics. A comparison between the reported use of the MWFs and the US production levels by decade found high correlations (r generally >0.7). Overall, the method described here is likely to have provided a systematic and reliable ranking that better reflects the variability of exposure to three types of MWFs than approaches applied in the past.

Tonsillectomy remains a questionable option for pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS).

PubMed

Windfuhr, Jochen P

2016-01-01

Background: Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) is a disease attributed to children with obsessive compulsive disorders (OCD) or tic disorders associated with streptococcal infections. Because otolaryngologists examine a large number of pediatric patients with recurrent streptococcal infections, tonsillectomy (TE) is a common option of therapy. This study was conducted to evaluate the efficacy of TE in patients presenting with verified PANDAS. Material and methods: A PubMed review was performed using search terms "tonsillectomy" and "PANDAS", "OCD", "compulsive" "pediatric autoimmune", "chorea" and "tic" limited by publication date of January 1, 1995, to July 31, 2015. Reviews without patients were not included in the review. Results: Nine papers matched our search criteria, including 6 case reports with 8 patients and 3 case series. Most case reports were in favor of TE, but this was by far not supported by the findings in the case series. The follow-up ranged from 2 to 36 months in case reports and from 24 to 36 in case series. Conclusion: Establishing the diagnosis of PANDAS is complicated because of underlying comorbidities in the field of neurology-psychiatry and the lack of a reliable biomarker. The positive outcome after TE as reported in case studies may be influenced by the postoperative medication and is not supported by the results of large-scale studies. In the light of the considerable postoperative morbidity rate, it appears wise to indicate TE for PANDAS only in supervised clinical studies.

Confirmed and probable cases of invasive Neisseria meningitidis (Nm) infection are reportable in New York City. We conducted a study to identify Nm among culture-negative reports of bacterial and viral meningitis. During the study period, 262 reports of suspected meningitis were eligible. Cerebrospinal fluid (CSF) specimens from 138 patients were obtained for testing. No Nm cases were detected. Results from real-time polymerase chain reaction and 16S on CSF specimens were concordant with hospital microbiology findings in 80%; however, other pathogenic organisms were detected in 14 culture-negative specimens. New York City's surveillance system appears to be effective at capturing cases of Nm meningitis. Nucleic acid testing is useful for detecting the presence of bacterial DNA when antibiotic therapy precedes lumbar puncture or bacterial cultures are negative. It remains unanswered whether culture-negative cases of Nm bacteremia are being missed by reportable disease surveillance. Copyright © 2015 Elsevier Inc. All rights reserved.

Measles is a major cause of childhood morbidity and mortality, accounting for nearly half of the morbidity associated with global vaccine preventable diseases. Regular outbreaks of Measles are reported in India, of which only a few are investigated. This study was conducted in the Shivpuri District of Madhya Pradesh (India) to investigate and asses various epidemiological factors associated with measles outbreak. A cross-sectional study was carried out in 30 randomly selected sub-centers in 8 blocks of the Shivpuri District of Madhya Pradesh, covering 212 villages, selected by cluster sampling. The villages, which had reported measles cases, were extensively investigated by the field teams through extensive house-to-house surveys during 12-19 May 2004. A total of 1204 cases with 14 deaths were reported with an attack rate of 6.2% and a case fatality rate of 1.2%. In this study, 17.7% of the cases reported post-measles complications with diarrhea as the most common post measles complication. The routine measles vaccine and Vitamin A supplementation in the area was also less than 30%. The majority of the cases had occurred in the unvaccinated children and in under 5 year old population. There are repeated outbreaks and a long delay in reporting of the cases. The occurrence of cases, in a reasonable proportion of the vaccinated population, points toward the fact that there is a possibility of a vaccine failure in older children. This study calls for an improved surveillance system, an improvement in the cold chain, and enhancements for measles vaccination if India is to achieve the goal of measles elimination.

The objectives of this study were to describe in detail the ascertainment and verification of prevalent and incident diabetes in the Dutch contributor to the European Prospective Investigation into Cancer and Nutrition (EPIC-NL cohort) and to examine to what extent ascertained diabetes agreed with general practitioner (GP) and pharmacy records. In total, 40,011 adults, aged 21 to 70 years at baseline, were included. Diabetes was ascertained via self-report, linkage to registers of hospital discharge diagnoses (HDD) and a urinary glucose strip test. Ascertained diabetes cases were verified against GP or pharmacist information using mailed questionnaires. At baseline, 795 (2.0%) diabetes cases were ascertained, and 1494 (3.7%) during a mean follow-up of ten years. The majority was ascertained via self-report only (56.7%), or self-report in combination with HDD (18.0%). After verification of ascertained diabetes cases, 1532 (66.9%) [corrected] were defined as having diabetes , 495 (21.6%) as non-diabetic individuals, and 262 (11.5%) as uncertain. Of the 1538 cases ascertained by self-report, 1350 (positive predictive value: 87.8%) were confirmed by GP or pharmacist. Cases ascertained via self-report in combination with HDD were most often confirmed (334 (positive predictive value: 96.0%)). Two out of three ascertained diabetes cases were confirmed to have been diagnosed with diabetes by their GP or pharmacist. Diabetes cases ascertained via self-report in combination with HDD had the highest confirmation.

To determine risk factors for progressive multifocal leukoencephalopathy (PML) in systemic lupus erythematosus (SLE) patients, and understand how underlying disease or treatment for SLE may be associated with PML in this population. Studies published in English between January 1, 1984 and October 31, 2014 that reported PML in adult SLE patients were included. Immunosuppression was defined as exposure to ≥1 immunosuppressant drug of interest at PML diagnosis: belimumab, rituximab, mycophenolate mofetil, azathioprine, cyclophosphamide, methotrexate and high-dose corticosteroids (>15 mg/day). Minimal immunosuppression was defined as low-dose corticosteroids (≤15 mg/day) and/or anti-malarials. Thirty-five publications met our inclusion criteria: four observational studies, two large case series, and 29 case reports that described 35 cases. Reported PML incidence rates among SLE patients based on observational studies ranged from 1.0 to 2.4 cases/100,000 person-years. Of the 35 case reports, three cases were exposed to no immunosuppressant drugs at PML diagnosis, five cases had minimal immunosuppression, 23 cases had immunosuppression, and four cases were indeterminate. The evidence from this literature review suggests that, while PML is a very rare disease in SLE patients, there does appear to be an increased risk of PML associated with SLE compared to the general population, potentially due to immunosuppression, other contributing factors in their underlying disease, treatments prescribed to manage disease, or some combination of these factors. Additional large observational studies, designed to assess exposure to drugs of interest and complicated treatment histories, are needed to provide further evidence about potential mechanisms contributing to the onset of PML in SLE patients. © The Author(s) 2016.

To give an overview of disciplinary cases regarding action taken by paediatricians and paediatric residents in cases of (suspected) child abuse and to discuss the considerations of the disciplinary board in these cases. Retrospective, descriptive study. We considered all disciplinary cases instigated from 2001 to 2013 against paediatricians or paediatric residents and selected complaints regarding action taken in cases of (suspected) child abuse. We divided these complaints into six categories and studied the considerations of the disciplinary board in these cases. From 33 disciplinary cases instigated from 2001 to 2013, we selected 76 complaints regarding action taken by paediatricians or paediatric residents in cases of (suspected) child abuse. The majority of these complaints concerned the reporting or requesting of information in the context of (suspected) child abuse. All of the complaints in the category 'unwarranted reporting of child abuse' were declared unfounded by the disciplinary judge. The disciplinary board declared all complaints unfounded in cases where the paediatrician or paediatric resident had followed the Dutch national protocol regarding reporting of child abuse and domestic violence. The disciplinary board examines whether action was taken in accordance with reasonable standards of professional competence and considers that paediatricians have an important role in identifying child abuse.

The efficiency of utilization of potential donors for organ transplantation in Saudi Arabia: a pilot study.

Organ shortage has been the main obstacle in the progress of organ transplantation in Saudi Arabia. The aim of this pilot study was to determine the percentage of potential donors among all deaths in Riyadh hospital intensive care units (ICUs). Mortality data were collected by a medical professional in each ICU and analyzed on weekly basis for 1 year (June 2001 through May 2002): The final analysis at the end of the year showed the number of brain death cases in all hospitals to be 114 out of 542 deaths. Fifty-four percent occurred in one hospital. Thirty-eight cases were reported to the Saudi Center for Organ Transplantation (33%). Documentation was completed in only 23 cases (60%). Only four cases became actual donors. In conclusion, there is underreporting of brain death cases. Dealing with the reported cases is inefficient since only four cases became actual donors out of 38. Improving the efficiency of ICUs in dealing with brain death cases (reporting, documentation, maintenance and consent) will require solving several problems at the medical, administrative, religious, and mass media levels.

Chronic mastitis is a prolonged inflammatory breast disease, and little is known about its etiology. We identified 85 cases and 112 controls from 5 hospitals in Morocco and Egypt. Cases were women with chronic mastitis (including periductal, lobular, granulomatous, lymphocytic, and duct ectasia with mastitis). Controls had benign breast disease, including fibroadenoma, benign phyllodes, and adenosis. Both groups were identified from histopathologically diagnosed patients from 2008 to 2011, frequency-matched on age. Patient interviews elicited demographic, reproductive, breastfeeding, and clinical histories. Cases had higher parity than controls (OR = 1.75, 1.62-1.90) and more reported history of contraception use (OR = 2.73, 2.07-3.61). Cases were less likely to report wearing a bra (OR = 0.56, 0.47-0.67) and less often used both breasts for breastfeeding (OR = 4.40, 3.39-5.72). Chronic mastitis cases were significantly less likely to be employed outside home (OR = 0.71, 0.60-0.84) and more likely to report mice in their households (OR = 1.63, 1.36-1.97). This is the largest case-control study reported to date on risk factors for chronic mastitis. Our study highlights distinct reproductive risk factors for the disease. Future studies should further explore these factors and the possible immunological and susceptibility predisposing conditions.

Behavioral Problems and Childhood Epilepsy: Parent vs Child Perspectives.

PubMed

Eom, Soyong; Caplan, Rochelle; Berg, Anne T

2016-12-01

To test whether the reported association between pediatric epilepsy and behavioral problems may be distorted by the use of parental proxy report instruments. Children in the Connecticut Study of Epilepsy were assessed 8-9 years after their epilepsy diagnosis (time-1) with the parent-proxy Child Behavior Check List (CBCL) (ages 6-18 years) or the Young Adult Self-Report (≥18 years of age). For children <18 years of age, parents also completed the Child Health Questionnaire, which contains scales for impact of child's illness on the parents. The same study subjects completed the Adult Self-Report 6-8 years later (time-2). Sibling controls were also tested. Case-control differences were examined for evidence suggesting more behavioral problems in cases with epilepsy than in controls based on proxy- vs self-report measures. At time-1, parent-proxy CBCL scores were significantly higher (worse) for cases than controls (n = 140 matched pairs). After adjustment for Child Health Questionnaire scales reflecting parent emotional and time impact, only 1 case-control difference on the CBCL remained significant. Self-reported Young Adult Self-Report scores did not differ between cases and controls (n = 42 pairs). At time-2, there were no significant self-reported case-control differences on the Adult Self-Report (n = 105 pairs). Parent-proxy behavior measures appear to be influenced by the emotional impact of epilepsy on parents. This may contribute to apparent associations between behavioral problems and childhood epilepsy. Self-report measures in older adolescents (>18 years of age) and young adults do not confirm parental perceptions. Evidence suggesting more behavioral problems in children with epilepsy should be interpreted in light of the source of information. Copyright © 2016 Elsevier Inc. All rights reserved.

If a case of physical child abuse is suspected in Germany, the general feeling is often that "it does not matter whether you make a report or not" because, generally, no conviction is made anyway. This study investigates the juridical analysis of complaint cases of physical child abuse [criminal complaint parag. 225 StGB (German penal code) with filial victim]. It focuses on the doctor's role and the impact of their practice in relation to a later conviction. It is based on the analysis of 302 files of the enquiry from 2004-2009 from the department of public prosecution in Cologne, Germany. Besides general epidemiological data on the reporting person, the affected child and the presumed offender, the documents were reassessed for the relevance of medical reports for successful convictions. Only 7% (n = 21) of 302 complaints led to a conviction. In 38.1% (n = 8) of those cases, a medical report was mentioned as a piece of evidence, and just in two cases a (legal) medical report was quoted and mentioned as relevant for the conviction. 50% of the complaint cases with legal medical expertise led to a trial. In contrast, only 30.2% with a common medical report and 7.3% without a report led to a trial. The results show how a medical report existed in only a few cases. In those cases, the rate of performed trials was higher than for those without a medical report, but the report played a minor part when reasoning a verdict.

Scrub typhus is a vector-borne disease, which has recently reemerged in China. In this study, we describe the distribution and incidence of scrub typhus cases in China from 2006 to 2014 and quantify differences in scrub typhus cases with respect to sex, age, and occupation. The results of our study indicate that the annual incidence of scrub typhus has increased during the study period. The number of cases peaked in 2014, which was 12.8 times greater than the number of cases reported in 2006. Most (77.97%) of the cases were reported in five provinces (Guangdong, Yunnan, Anhui, Fujian, and Shandong). Our study also demonstrates that the incidence rate of scrub typhus was significantly higher in females compared to males (P < 0.001) and was highest in the 60-69 year age group, and that farmers had a higher incidence rate than nonfarmers (P < 0.001). Different seasonal trends were identified in the number of reported cases between the northern and southern provinces of China. These findings not only demonstrate that China has experienced a large increase in scrub typhus incidence, but also document an expansion in the geographic distribution throughout the country. © The American Society of Tropical Medicine and Hygiene.

Cases reported in the period of 2001-2011 from 14/18 CL endemic countries were included in this study by using two spreadsheet to collect the data. Two indicators were analyzed: CL cases and incidence rate. The local regression method was used to analyze case trends and incidence rates for all the studied period, and for 2011 the spatial distribution of each indicator was analyzed by quartile and stratified into four groups. From 2001-2011, 636,683 CL cases were reported by 14 countries and with an increase of 30% of the reported cases. The average incidence rate in the Americas was 15.89/100,000 inhabitants. In 2011, 15 countries reported cases in 180 from a total of 292 units of first subnational level. The global incidence rate for all countries was 17.42 cases per 100,000 inhabitants; while in 180 administrative units at the first subnational level, the average incidence rate was 57.52/100,000 inhabitants. Nicaragua and Panama had the highest incidence but more cases occurred in Brazil and Colombia. Spatial distribution was heterogeneous for each indicator, and when analyzed in different administrative level. The results showed different distribution patterns, illustrating the limitation of the use of individual indicators and the need to classify higher-risk areas in order to prioritize the actions. This study shows the epidemiological patterns using secondary data and the importance of using multiple indicators to define and characterize smaller territorial units for surveillance and control of leishmaniasis.

To review studies on structural pulmonary and cardiac changes in SUDEP cases as well as studies showing pulmonary or cardiac structural changes in living epilepsy patients. We conducted electronic literature searches using the PubMed database for articles published in English, regardless of publication year, that included data on cardiac and/or pulmonary structural abnormalities in SUDEP cases or in living epilepsy patients during the postictal period. Fourteen postmortem studies reported pulmonary findings in SUDEP cases. Two focused mainly on assessing lung weights in SUDEP cases versus controls; no group difference was found. The other 12 reported descriptive autopsy findings. Among all SUDEP cases with available descriptive postmortem pulmonary examination, 72% had pulmonary changes, most often pulmonary edema/congestion, and, less frequently, intraalveolar hemorrhage. Eleven studies reported on cardiac pathology in SUDEP. Cardiac abnormalities were found in approximately one-fourth of cases. The most common findings were myocyte hypertrophy and myocardial fibrosis of various degrees. Among living epilepsy patients, postictal pulmonary pathology was the most commonly reported pulmonary abnormality and the most common postictal cardiac abnormality was transient left ventricular dysfunction - Takotsubo or neurogenic stunned myocardium. Cardiac and pulmonary pathological abnormalities are frequent among SUDEP cases, most commonly pulmonary edema/congestion and focal interstitial myocardial fibrosis. Most findings are not quantified, with subjective elements and undefined interobserver reliability, and lack of controls such as matched epilepsy patients who died from other causes. Further, studies have not systematically evaluated potential confounding factors, including postmortem interval to autopsy, paramedic resuscitation and IV fluids administration, underlying heart/lung disease, and risk factors for cardiac or pulmonary disease. Prospective studies with controls are needed to define the heart and lung changes in SUDEP and understand their potential relationship to mechanisms of death in SUDEP. Copyright © 2017 Elsevier Inc.

OBJECTIVE: The objective of the present study was to describe the epidemiology of reportable enteric illness in Ontario’s Waterloo region, including comparing calculated incidence rates with published rates, and adjusting for under-reporting to determine the number of community cases, where published data were available. METHODS: Descriptive analyses were performed on reportable disease data for 13 enteric diseases collected in the Waterloo region from 1990 to 2004. Poisson and negative binomial regression analyses were used to investigate differences in incidence rates among age, sex, the 15 years of data and seasons. Disease-specific incidence rates were calculated and compared with the literature, where possible. Under-reporting ratios from the literature were applied to estimate the number of cases of campylobacteriosis, nontyphoidal salmonellosis and verotoxigenic Escherichia coli infection at the community level. RESULTS: Over the study period, the average annual age- and sex-adjusted incidence rates per 100,000 population were highest for campylobacteriosis (49.69 cases), followed by giardiasis (31.87 cases) and nontyphoidal salmonellosis (25.97 cases). The incidence of most enteric illnesses peaked in the summer. The highest incidence occurred in young children, followed by adults in their 20s. Diarrhea (85.4%) was the most frequently reported symptom, food (57.4%) was the most commonly reported probable source, and home (41.7%) and travel (37.0%) were the two most frequently reported risk settings. CONCLUSIONS: Enteric illness was a significant health burden in the Waterloo region from 1990 to 2004. Because reportable disease data are subject to under-reporting, it is likely that the true burden is greater than estimated in the present study. PMID:20808465

This study aims to discuss the correlation between daily reported H7N9 cases and stock price indices in China. Information on daily reported H7N9 cases and stock market sectors indices between February 19, 2013 and March 31, 2014 were collected. A distributed lag non-linear model was used to describe the variation trend for the stock indices. The daily reported number of H7N9 cases was associated with the closing price of the Avian Influenza Sector Index (P < 0.05) and the opening price of the Shanghai Composite Index (P = 0.029). The Avian Influenza Sector Index decreased with increasing of daily reported case number when daily reported cases ≤ 4. Case number was associated with the opening/closing price of the Chinese Traditional Medicine Sector Index, the Biological Product Sector Index, and the Biomedicine Sector Index (P < 0.05). New or reemerging infectious diseases epidemic cause economic loss which is reflected in movements in stock prices.

Few cases of psoas abscesses (PA) during chronic Q fever have been reported, and the route of transmission remains unknown. Here, we report a new case and have performed a systematic literature review to determinate the spreading route of this complication. Medline, EMBASE and Web of Science were searched. Local spreading was supported by endocarditis exclusion, evidence of vascular infection and absence of distantly infected sites. Among 275 retrieved references, 179 were initially rejected, and 85 additional references were rejected after full-text review. A total of 11 studies, reporting 13 cases, were included. Additionally, we reported one new case. A total of 14/14 cases reached Q fever vascular infection diagnostic criteria, and 7/14 provided adequate evidence supporting a causal relationship between Q fever vascular infection and PA. All patients presented aorta defects. In conclusion, Q fever PA results from the spreading of a local infection and occurs specifically in patients presenting a vascular graft or an abdominal aortic aneurysm.

To characterize maternal Zika virus (ZIKV) infection and complement the evidence base for the WHO interim guidance on pregnancy management in the context of ZIKV infection. We searched the relevant database from inception until March 2016. Two review authors independently screened and assessed full texts of eligible reports and extracted data from relevant studies. The quality of studies was assessed using the Newcastle-Ottawa Scale (NOS) and the National Institute of Health (NIH) tool for observational studies and case series/reports, respectively. Among 142 eligible full-text articles, 18 met the inclusion criteria (13 case series/reports and five cohort studies). Common symptoms among pregnant women with suspected/confirmed ZIKV infection were fever, rash, and arthralgia. One case of Guillain-Barré syndrome was reported among ZIKV-infected mothers, no other case of severe maternal morbidity or mortality reported. Complications reported in association with maternal ZIKV infection included a broad range of fetal and newborn neurological and ocular abnormalities; fetal growth restriction, stillbirth, and perinatal death. Microcephaly was the primary neurological complication reported in eight studies, with an incidence of about 1% among newborns of ZIKV infected women in one study. Given the extensive and variable fetal and newborn presentations/complications associated with prenatal ZIKV infection, and the dearth of information provided, knowledge gaps are evident. Further research and comprehensive reporting may provide a better understanding of ZIKV infection in pregnancy and attendant maternal/fetal complications. This knowledge could inform the creation of effective and evidence-based strategies, guidelines and recommendations aimed at the management of maternal ZIKV infection. Adherence to current best practice guidelines for prenatal care among health providers is encouraged, in the context of maternal ZIKV infection.

2016-01-01

Objective The study updates and enhances clinicians' knowledge about clinical case reports (CCRs) and encourages publication of such articles. Methods The author developed and offered a session about BMJ Case Reports to medical and surgical departments in the University Hospital of Móstoles. The session reviewed the contents and add-on services of the journal, conventional and alternative indicators of journal quality, use of CCRs to share valuable clinical lessons, and manuscript preparation and submission. Results The main result of these sessions was submission of eight CCRs to BMJ Case Reports, of which four were accepted. One submitting author was invited to serve as peer reviewer for the journal. Other clinicians are preparing five new CCRs for submission to BMJ Case Reports or other journals. Conclusions The learning sessions were successful in promoting writing and publication of CCRs. Young staff and postgraduate residents seemed especially encouraged to publish CCRs that had already been presented in their departmental sessions. As a librarian, I gained experience in CCR publication and reinforced my position as an essential supporter of the hospital's teaching and publishing activity. PMID:27822158

Comparison of victims' reports and court records of intimate partner violence perpetrators' criminal case outcomes.

Bell, Margret E; Larsen, Sadie E; Goodman, Lisa A; Dutton, Mary Ann

2013-09-01

Intimate partner violence (IPV) victims often report feeling confused and uninformed about court proceedings, including even about the final disposition of the case against their partner. This is problematic because victims' decisions in responding to subsequent abuse may be significantly influenced by their beliefs about the outcomes of prior court experiences. Also, researchers often rely on victim report of court case outcomes; discrepancies between women's reports and official records may account for some of the conflicting findings in the empirical literature. In the current study, we compared the reports of case outcome given by 81 women recruited immediately after the final hearing of an IPV-related criminal case against their perpetrator with court records of case outcome. Findings revealed a fair level of agreement between women's reports and court files that was significantly different from the level of agreement expected by chance, but far from perfect. Level of agreement increased substantially when cases involving suspended sentences were removed. In reviewing these findings, we discuss the extent to which results can or cannot be interpreted as reflecting the accuracy of women's knowledge and review their implications for IPV researchers and court systems.

Leishmaniasis is an important health problem in several countries in the Americas and cases notification is limited and underreported. In 2008, the Pan American Health Organization (PAHO/WHO) met with endemic countries to discuss the status and need of improvement of systems region-wide. The objective is to describe the temporal and spatial distribution of cutaneous leishmaniasis (CL) cases reported to PAHO/WHO by the endemic countries between 2001 and 2011 in the Americas. Methods Cases reported in the period of 2001–2011 from 14/18 CL endemic countries were included in this study by using two spreadsheet to collect the data.

Most studies of mobile phone use are case-control studies that rely on participants' reports of past phone use for their exposure assessment. Differential errors in recalled phone use are a major concern in such studies. INTERPHONE, a multinational case-control study of brain tumour risk and mobile phone use, included validation studies to quantify such errors and evaluate the potential for recall bias. Mobile phone records of 212 cases and 296 controls were collected from network operators in three INTERPHONE countries over an average of 2 years, and compared with mobile phone use reported at interview. The ratio of reported to recorded phone use was analysed as measure of agreement. Mean ratios were virtually the same for cases and controls: both underestimated number of calls by a factor of 0.81 and overestimated call duration by a factor of 1.4. For cases, but not controls, ratios increased with increasing time before the interview; however, these trends were based on few subjects with long-term data. Ratios increased by level of use. Random recall errors were large. In conclusion, there was little evidence for differential recall errors overall or in recent time periods. However, apparent overestimation by cases in more distant time periods could cause positive bias in estimates of disease risk associated with mobile phone use.

Boric acid for recurrent vulvovaginal candidiasis: the clinical evidence.

2011-08-01

Recurrent vulvovaginal candidiasis (VVC) remains a challenge to manage in clinical practice. Recent epidemiologic studies indicate that non-albicans Candida spp. are more resistant to conventional antifungal treatment with azoles and are considered as causative pathogens of vulvovaginal candidiasis. We searched PubMed and Scopus for studies that reported clinical evidence on the intravaginal use of boric acid for vulvovaginal candidiasis. We identified 14 studies (2 randomized clinical trials [RCTs], 9 case series, and 4 case reports) as eligible for inclusion in this review. Boric acid was compared with nystatin, terconazole, flucytosine, itraconazole, clotrimazole, ketoconazole, fluconazole, buconazole, and miconazole; as monotherapy, boric acid was studied in 7 studies. The mycologic cure rates varied from 40% to 100% in patients treated with boric acid; 4 of the 9 included case series reported statistically significant outcomes regarding cure (both mycologic and clinical) rates. None of the included studies reported statistically significant differences in recurrence rates. Regarding the adverse effects caused by boric acid use, vaginal burning sensation (<10% of cases), water discharge during treatment, and vaginal erythema were identified in 7 studies. Our findings suggest that boric acid is a safe, alternative, economic option for women with recurrent and chronic symptoms of vaginitis when conventional treatment fails because of the involvement of non-albicans Candida spp. or azole-resistant strains.

To estimate the reported incidence of occupational hypersensitivity pneumonitis (OHP) in the UK and to consider whether the pattern of attributed causation has changed over time. All cases of OHP reported to the SWORD scheme between January 1996 and December 2015 were classified into 1 of 10 categories of the suspected agent. Cases were grouped into four 5-year time periods to examine any changing pattern in incidence or suspected causation. For each time period, the annual incidence was calculated using the estimated number of reported cases and the working population of the UK. Between 1996 and 2015, there were 202 actual cases of OHP reported to SWORD, equating to an estimated 818 cases, when adjusting for the sampling ratio. Over this period, the annual UK incidence was 1.4 per million workers. The mean (SD) age of reported cases was 52 (13) years, and cases were four-times more likely to be men than women. Over the study period, there was a fall in the proportion of cases reported to be due to agricultural exposures (44-12%), and an increase in cases due to metalworking fluids (MWFs, 2-45%). Over the last 20 years, the incidence of OHP in the UK has been ∼1-2 cases per million workers per year. Working with water-based MWFs is now the most commonly suspected causative exposure for OHP cases reported to the SWORD scheme in the UK. Published by the BMJ Publishing Group Limited.

2012-10-01

Permanent nerve involvement has been reported following inferior alveolar nerve blocks. This study provides an update on cases reported to one unit in the preceding six years. Lidocaine was associated with 25 percent of cases, articaine with 33 percent of cases, and prilocaine with 34 percent of cases. It does appear that inferior alveolar nerve blocks can cause permanent nerve damage with any local anesthetic, but the incidences may vary.

Work related asthma (WRA) is one of the most frequently reported occupational lung diseases in a number of industrialised countries. A better understanding of work aggravated asthma (WAA), as well as work related new onset asthma (NOA), is needed to aid in prevention efforts. WAA and NOA in the United States were compared using cases reported to the National Institute for Occupational Safety and Health (NIOSH) from four state Sentinel Event Notification Systems for Occupational Risks (SENSOR) surveillance programmes for 1993-95. A total of 210 WAA cases and 891 NOA cases were reported. WAA cases reported mineral and inorganic dusts as the most common exposure agent, as opposed to NOA cases, in which diisocyanates were reported most frequently. A similar percentage of WAA and NOA cases still experienced breathing problems at the time of the interview or had visited a hospital or emergency room for work related breathing problems. NOA cases were twice as likely to have applied for workers' compensation compared with WAA cases. However, among those who had applied for worker compensation, approximately three-fourths of both WAA and NOA cases had received awards. The services and manufacturing industrial categories together accounted for the majority of both WAA (62%) and NOA (75%) cases. The risk of WAA, measured by average annual rate, was clearly the highest in the public administration (14.2 cases/10(5)) industrial category, while the risk of NOA was increased in both the manufacturing (3.2 cases/10(5)) and public administration (2.9 cases/10(5)) categories. WAA cases reported many of the same adverse consequences as NOA cases. Certain industries were identified as potential targets for prevention efforts based on either the number of cases or the risk of WAA and NOA.

Andrographis paniculata (andrographis) is one of the herbal products that are widely used for various indications. Hypersensitivity reactions have been reported among subjects receiving Andrographis paniculata in Thailand. Understanding of characteristics of patients, adverse events, and clinical outcomes is essential for ensuring population safety.This study aimed to describe the characteristics of hypersensitivity reactions reported in patients receiving andrographis containing products in Thailand using national pharmacovigilance database. Thai Vigibase data from February 2001 to December 2012 involving andrographis products were used. This database includes the reports submitted through the spontaneous reporting system and intensive monitoring programmes. The database contained patient characteristic, adverse events associated with andrographis products, and details on seriousness, causality, and clinical outcomes. Case reports were included for final analysis if they met the inclusion criteria; 1) reports with andrographis being the only suspected cause, 2) reports with terms consistent with the constellation of hypersensitivity reactions, and 3) reports with terms considered critical terms according to WHO criteria. Descriptive statistics were used. A total of 248 case reports of andrographis-associated adverse events were identified. Only 106 case reports specified andrographis herbal product as the only suspected drug and reported at least one term consistent with constellation of hypersensitivity reactions. Most case reports (89%) came from spontaneous reporting system with no previously documented history of drug allergy (88%). Of these, 18 case reports were classified as serious with 16 cases requiring hospitalization. For final assessment, the case reports with terms consistent with constellation of hypersensitivity reactions and critical terms were included. Thirteen case reports met such criteria including anaphylactic shock (n = 5), anaphylactic reaction (n = 4) and angioedema (n = 4). Time to development of symptoms ranged from 5 minutes to 1 day. The doses of andrographis used varied from 352 mg to 1,750 mg. Causality assessment of 13 case reports were certain (n = 3), probable (n = 8) and possible (n = 2). Our findings suggested that hypersensitivity reactions have been reported among patients receiving Andrographis paniculata. Healthcare professionals should be aware of this potential risk. Further investigation of the causal relationship is needed; meanwhile including hypersensitivity reactions for andrographis product labeling should be considered.

OBJECTIVE Uterine leiomyomata represent a major public health problem for black women in the United States, but limited data are available on age–incidence curves in this high-risk population. We estimated overall and age-specific incidence rates for self-reported uterine leiomyomata in a large cohort of African-American women in the United States. METHODS Data were derived from the Black Women’s Health Study, an ongoing prospective cohort study of 59,000 black women from across the United States who were aged 21–69 years at baseline (ie, 1995). From March 1997 through March 2001, we followed up 22,895 premenopausal women with no prior diagnosis of uterine leiomyoma. Poisson regression was used to estimate overall and age-specific incidence rates and 95% confidence intervals (CIs) for self-reported uterine leiomyoma. In a subset of 248 patients who were selected randomly from the total case group, the self-reported diagnosis was verified in 96% of cases who released their medical records. RESULTS During 76,711 woman-years of follow-up, 2,637 incident cases of uterine leiomyomata reported as confirmed by pelvic examination (n = 358), ultrasonography (n = 2,006), or hysterectomy (n = 273) were observed. Incidence rates per 1,000 woman-years were 34.4 (95% CI 33.1–35.7) for all cases combined, 29.7 (95% CI 28.5–30.9) for cases confirmed by ultrasonography or hysterectomy, and 3.6 (95% CI 3.2–4.0) for cases confirmed by hysterectomy. The incidence rate peaked at ages 40–44 years for all cases combined (incidence rate 45.6, 95% CI 42.0–49.5) and for cases confirmed by ultrasonography or hysterectomy (incidence rate 39.8, 95% CI 36.5–43.4), and peaked at ages 45–49 years for cases confirmed by hysterectomy (incidence rate 8.3, 95% CI 6.4–10.7). CONCLUSION Overall incidence rates for self-reported uterine leiomyomata were consistent with other U.S studies in black women and confirmed a high burden of disease in this population. Age-specific incidence rates showed a later peak incidence than that observed among U.S. black women in previous studies. LEVEL OF EVIDENCE II-2 PMID:15738025

High Dengue Case Capture Rate in Four Years of a Cohort Study in Nicaragua Compared to National Surveillance Data

Dengue is a major public health problem in tropical and subtropical regions; however, under-reporting of cases to national surveillance systems hinders accurate knowledge of disease burden and costs. Laboratory-confirmed dengue cases identified through the Nicaraguan Pediatric Dengue Cohort Study (PDCS) were compared to those reported from other health facilities in Managua to the National Epidemiologic Surveillance (NES) program of the Nicaraguan Ministry of Health. Compared to reporting among similar pediatric populations in Managua, the PDCS identified 14 to 28 (average 21.3) times more dengue cases each year per 100,000 persons than were reported to the NES. Applying these annual expansion factors to national-level data, we estimate that the incidence of confirmed pediatric dengue throughout Nicaragua ranged from 300 to 1000 cases per 100,000 persons. We have estimated a much higher incidence of dengue than reported by the Ministry of Health. A country-specific expansion factor for dengue that allows for a more accurate estimate of incidence may aid governments and other institutions calculating disease burden, costs, resource needs for prevention and treatment, and the economic benefits of drug and vaccine development.

Clinical case report. Symptoms in the face and jaw are common after whiplash. Few studies have reported cervicogenic headache in a trigeminal nerve distribution, and no published studies could be found describing such symptoms experienced bilaterally after whiplash. The objective of the current case report was to detail the clinical reasoning and management of an uncommon patient presentation. The 41-year-old female patient of the current case complained of shooting pain in the jaw, cheek and forehead beginning 7 days after her accident. No imaging was performed, and examination ruled out serious pathology. The patient was treated primarily with deep neck flexor (DNF) and proprioceptive training for 10 visits over an 8-week period. The Numeric Pain Rating Scale improved from 2/10 to 0/10, the Neck Disability Index improved from 17/50 to 1/50, and the Neck Flexor Muscle Endurance Test improved from 13 to 30 s. The patient remained symptom-free at 4-month follow-up. The current case report describes a patient presentation unique to the literature. Significant changes were seen by week 3 with DNF and proprioceptive training. Additional research is required to determine the effectiveness of this intervention in similar presentations.

Background Asthma and obliterative bronchiolitis (OB) cases have occurred among styrene-exposed workers. We aimed to investigate styrene as a risk factor for non-malignant respiratory disease (NMRD). Methods From a literature review, we identified case reports and assessed cross-sectional and mortality studies for strength of evidence of positive association (i.e., strong, intermediate, suggestive, none) between styrene exposure and NMRD-related morbidity and mortality. Results We analyzed 55 articles and two unpublished case reports. Ten OB cases and eight asthma cases were identified. Six (75%) asthma cases had abnormal styrene inhalation challenges. Thirteen (87%) of 15 cross-sectional studies and 12 (50%) of 24 mortality studies provided at least suggestive evidence that styrene was associated with NMRD-related morbidity or mortality. Six (66%) of nine mortality studies assessing chronic obstructive pulmonary disease-related mortality indicated excess mortality. Conclusions Available evidence suggests styrene exposure is a potential risk factor for NMRD. Additional studies of styrene-exposed workers are warranted. PMID:28079275

Potential effect of CAD systems on the detection of actionable nodules in chest CT scans during routine reporting

The purpose of the presented study was to determine the impact of two different CAD systems used as concur-rent reader for detection of actionable nodules (>4 mm) on the interpretation of chest CT scans during routine reporting. Fifty consecutive MDCT scans (1 mm or 1.25 mm slice thickness, 0.8 mm reconstruction increment) were se-lected from clinical routine. All cases were read by a resident and a staff radiologist, and a written report was available in the radiology information system (RIS). The RIS report mentioned at least one actionable pulmonary nodule in 18 cases (50%) and did not report any pulmonary nodule in the remaining 32 cases. Two different recent CAD systems were independently applied to the 50 CT scans as concurrent reader with two radiologists: Siemens LungCare NEV and MEDIAN CAD-Lung. Two radiologists independently reviewed the CAD results and determined if a CAD result was a true positive or a false positive finding. Patients were classified into two groups: in group A if at least one actionable nodule was detected and in group B if no actionable nodules were found. The effect of CAD on routine reporting was simulated as set union of the findings of routine reporting and CAD thus applying CAD as concurrent reader. According to the RIS report group A (patients with at least one actionable nodule) contained 18 cases (36% of all 50 cases), and group B contained 32 cases. Application of a CAD system as concurrent reader resulted in detec-tion of additional CT scans with actionable nodules and reclassification into group A in 16 resp. 18 cases (radi-ologist 1 resp. radiologist 2) with Siemens NEV and in 19 resp. 18 cases with MEDIAN CAD-Lung. In seven cases MEDIAN CAD-Lung and in four cases Siemens NEV reclassified a case into group A while the other CAD system missed the relevant finding. Sensitivity on a nodule (>4 mm) base was .45 for Siemens NEV and .55 for MEDIAN CAD-Lung; the difference was not yet significant (p=.077). In our study use of CAD as second reader in routine reporting doubled the percentage of patients with actionable nodules larger than 4 mm.

Undereporting of acute pesticide poisoning in Tanzania: modelling results from two cross-sectional studies.

Acute pesticide poisoning (APP) is known to cause serious injuries to end users globally but the magnitude of this problem in Tanzania is not well known. This study aimed to determine the extent and pattern of underreporting of APP in Tanzania to inform the development of a surveillance system and appropriate interventions. This study integrates findings from two recent Tanzanian studies. A household survey established the proportion of poisoned farmers in a typical rural area who reported to hospital for a pesticide poisoning. Only 5 of the 112 farmers who reported attending hospital due to poisonings could be traced in medical records at the facilities they claimed to have attended. The 95% confidence interval for this ratio (5/112) was used to generate a high and low boundary for the estimates. Three under-estimation factors were generated for sensitivity analysis to adjust for under-reporting. A review of health facilities in three regions of Tanzania collected prospective data on admissions for APP in 2006 to generate population-based APP incidence rates stratified by circumstances of poisoning (occupational, accidental, suicide, and unknown). Sensitivity analysis was conducted involving adjustment for high and low boundaries of the under-reporting of occupational APP and an adjustment for different scenario allocations of cases with 'unknown' circumstances to different combinations of known circumstances. The study estimated the rate of occupational poisoning as ranging from 11.3-37.7 cases/million to 84.3-279.9 cases per million. The rate of all poisonings (occupational and non-occupational) ranged from 24.45-48.01 cases per million to 97.37-290.29 cases per million. Depending on the choice of scenario and under-reporting correction factor used, occupational APP could comprise from 52.2 to 96% of all APP cases. The study confirms that data on APP in Tanzanian hospitals are poorly reported and that occupational circumstances are particularly overlooked in routine facility-based surveillance. Occupational APP needs to be taken more seriously in addressing prevention measures. A comprehensive surveillance system for APP should consider multiple data sources including community self-reporting in order to achieve better coverage.

Countries in the different stages of pre-elimination, elimination, and prevention of reintroduction are required to report the number of indigenous and imported malaria cases to the World Health Organization (WHO). However, these data have not been systematically analysed at the global level. For the period 2007 to 2013, we aimed to report on 1) the proportion of countries providing data on the origin of malaria cases and 2) the origin of malaria cases in countries classified as being in the stages of pre-elimination, elimination and prevention of reintroduction. An observational study using annual data reported through routine health information systems to the WHO Global Malaria Programme between 2007 and 2013. For all countries classified as being in pre-elimination, elimination, and prevention of reintroduction in the year 2013, there has been a substantial decrease in the total number of indigenous malaria cases, from more than 15,000 cases reported in 2007 to less than 4,000 cases reported in 2013. However, the total number of imported malaria cases has increased over that time period, from 5,600 imported cases in 2007 to approximately 6,800 in 2013. Vigilant monitoring of the numbers of imported and indigenous malaria cases at national and global levels as well as appropriate strategies to target these cases will be critical to achieve malaria eradication.

This study summarizes the outcome of all investigations of elder abuse conducted in Forsyth County, North Carolina, during a 3-year period ending December 1991. Of the 123 cases investigated, 23 were confirmed as elder abuse. There were no statistically significant differences in age, sex, race, living arrangements, mental status, mobility, or source of report between confirmed and unconfirmed cases. Unconfirmed compared to confirmed cases were more likely to reside in a nursing home and/or to be ill. The most frequently substantiated charge was exploitation of resources (46%). Only 3% of charges of physical abuse were substantiated. Among confirmed cases, 70% were offered and accepted protective services.

To survey the reporting quality of traditional Chinese medicine (TCM) case reports published in recent years and understand the common problems. The assessment results would lay the foundation for the development of recommendations for case report in Chinese medicine. This survey determined the reporting quality of cases with Chinese herbal decoction, Chinese proprietary medicine, acupuncture, moxibustion and other traditional therapies published in 20 core medical journals of China by searching the China Academic Journals Full-text Database from 2006 to 2010. Fifty survey items in 16 domains were used to determine the reporting quality. One point was assigned to each item (Yes=1 point; No=0 point), and total score was 50 points. The domain of treatment was assessed independently, ranging from 2 to 9 items for different TCM interventions. The total of 1,858 case reports, covering 3,417 cases were included to analyze from 13 out of 20 core medical journals of China. There were 74.8% of them did not identify the nature of study in title, while 73.9% did not comprise an abstract. Incomplete reporting was found in discussions/ comment, and only 38.9% had made recommendations or take-away messages. Figures and tables were infrequently used. Three cases cited the full names of patients, but without declaring that any consent was obtained. Over 90% reported the symptoms and signs of TCM, and characteristics on tongue and pulse, but less than 50% did mention other medical history and diagnostic rationale. More than 90% treatments of the included cases were herbal decoction, with clear reporting on the ingredients and dosages. However, the reporting rate of the dosages of each ingredient was just 48.4%. Almost none reported the quality control of crude herbs, manufacturers and lot numbers of herbal proprietary medicine. Besides, advices and precautions on diet, emotions and living were rare to be illustrated. Systematic reporting recommendations are urged to develop for improving the contents and format of case reports in TCM.

Congenital cytomegalovirus (cCMV) infection can result in poor outcomes including cerebral palsy (CP). The aim of this study was to describe the incidence and comorbidities of CP reported to the Australian Cerebral Palsy Register (ACPR) as attributed to cCMV infection. This was a retrospective population-based study. Cases were drawn from Australian state CP registers with population level ascertainment, 1993 to 2003 (n=2265; 56.4% males, Gross Motor Function Classification System [GMFCS] ratings available for Victorian cases only: 70% GMFCS levels I to III and 30% GMFCS levels IV to V). Clinical data were extracted and cases with cCMV reported as a known cause were compared with cases where cCMV was not reported. Children with cCMV (n=34; 12 males, 22 females; mean [SD] gestational age, 36.4 wk [4.4], range 24-41 wk) accounted for 1.5% of CP cases; 2.9 per 100,000 live births, (95% confidence intervals 1.9-3.9). When compared with CP cases where cCMV was not reported, proportionally, more CP cases with cCMV were born to younger mothers (p<0.001), were female (64% vs 43%, p=0.014), had spastic quadriplegia (73% vs 21%, p<0.001), required wheeled mobility i.e. GMFCS IV or V (78% vs 28%, p<0.001), had epilepsy (70% vs 30%, p<0.001), deafness (40% vs 2%, p<0.001), functional blindness (20% vs 5%, p<0.001), and severe communication impairment (71% vs 25%, p<0.001). cCMV is an important potentially preventable cause of CP and is associated with severe disability and female sex in cases reported to the ACPR. Future studies utilising prospective sample collection for cCMV testing are needed to confirm these findings. © 2014 Mac Keith Press.

Observational evidence and strength of evidence domains: case examples

PubMed Central

2014-01-01

Background Systematic reviews of healthcare interventions most often focus on randomized controlled trials (RCTs). However, certain circumstances warrant consideration of observational evidence, and such studies are increasingly being included as evidence in systematic reviews. Methods To illustrate the use of observational evidence, we present case examples of systematic reviews in which observational evidence was considered as well as case examples of individual observational studies, and how they demonstrate various strength of evidence domains in accordance with current Agency for Healthcare Research and Quality (AHRQ) Evidence-based Practice Center (EPC) methods guidance. Results In the presented examples, observational evidence is used when RCTs are infeasible or raise ethical concerns, lack generalizability, or provide insufficient data. Individual study case examples highlight how observational evidence may fulfill required strength of evidence domains, such as study limitations (reduced risk of selection, detection, performance, and attrition); directness; consistency; precision; and reporting bias (publication, selective outcome reporting, and selective analysis reporting), as well as additional domains of dose-response association, plausible confounding that would decrease the observed effect, and strength of association (magnitude of effect). Conclusions The cases highlighted in this paper demonstrate how observational studies may provide moderate to (rarely) high strength evidence in systematic reviews. PMID:24758494

The purpose of this study was to describe time trends in response rates in case-control studies of cancer and identify study design factors that influence response rate. We reviewed 370 case-control studies of cancer published in 12 journals during indicator years in each of the last four decades. We estimated time trends of response rates and reasons for nonresponse in each of the following types of study subjects: cases, medical source controls, and population controls. We also estimated response rates according to characteristics of study context. Median response rates among cases and population controls were between 75% and 80% in the 1970s. Between 1971 and 2010, study response rates declined by 0.31% per year for cases and 0.78% for population controls. Only a minority of studies reported reasons for nonparticipation; subject refusal was the most common reported reason. Studies conducted in North America had lower median response rates than studies conducted in Europe. In-person and telephone interviews elicited higher response rates than mail questionnaires. Response rates from case-control studies of cancer have declined, and this could threaten the validity of results derived from these studies. Copyright © 2018 Elsevier Inc. All rights reserved.

Child sexual abuse (CSA) is a global problem that affects children of all ages, and the evaluation of these victims by psychologic and gynecologic experts in pediatric emergency departments is an important issue. Few data are available on the characteristics of children admitted to pediatric emergency department with recurrent CSA and delayed reported CSA. The aim of the present study was to describe the clinical features of, and risk factors for, recurrent CSA and delayed reported CSA. The study retrospectively analyzed victims of CSA who were admitted to a pediatric emergency department. Chi-square tests and univariate analyses were performed to assess the risk factors of recurrent or delayed reported CSA. Of the 91 CSA cases, 32 (35.2%) were recurrent assaults. Of the 70 cases recorded the duration of the event, 22 (31.4%) were delayed report cases. Comparisons of the non-recurrent and recurrent CSA assault groups revealed a significant increase in comorbidities (odds ratio [OR]: 4.46, 95% confidence interval [CI]: 1.54-12.93), acute psychiatric problems (OR: 3.18, CI: 1.26-8.06), attempted suicide (OR: 4.23, CI: 1.28-13.99), and the need for treatment with antipsychotic medications (OR: 5.57, CI: 1.37-22.65). Compared with non-delayed reported cases, the delay reported cases of CSA were significantly more likely to have anxiety (P < .05). The CSA victims in the present study exhibited acute medical and/or psychosocial problems, which indicate that pediatric emergency professionals have a responsibility to look for and recognize particular characteristics in these victims.

Improper prescribing of controlled substances contributes to opioid addictions and deaths by overdose. Studies conducted to-date have largely lacked a theoretical framework and ignored the interaction of individual with environmental factors. We conducted a mixed-method analysis of published reports on 100 cases that occurred in the United States. An average of 17 reports (e.g., from medical boards) per case were coded for 38 dichotomous variables describing the physician, setting, patients, and investigation. A theory on how the case occurred was developed for each case. Explanatory typologies were developed and then validated through hierarchical cluster analysis. Most cases involved physicians who were male (88%), >40 years old (90%), non-board certified (63%), and in small private practices (97%); 54% of cases reported facts about the physician indicative of self-centered personality traits. Three explanatory typologies were validated. Increasing oversight provided by peers and trainees may help prevent improper prescribing of controlled substances. PMID:28663601

Tonsillectomy remains a questionable option for pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS)

PubMed Central

Windfuhr, Jochen P.

2016-01-01

Background: Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) is a disease attributed to children with obsessive compulsive disorders (OCD) or tic disorders associated with streptococcal infections. Because otolaryngologists examine a large number of pediatric patients with recurrent streptococcal infections, tonsillectomy (TE) is a common option of therapy. This study was conducted to evaluate the efficacy of TE in patients presenting with verified PANDAS. Material and methods: A PubMed review was performed using search terms “tonsillectomy” and “PANDAS”, “OCD”, “compulsive” “pediatric autoimmune”, “chorea” and “tic” limited by publication date of January 1, 1995, to July 31, 2015. Reviews without patients were not included in the review. Results: Nine papers matched our search criteria, including 6 case reports with 8 patients and 3 case series. Most case reports were in favor of TE, but this was by far not supported by the findings in the case series. The follow-up ranged from 2 to 36 months in case reports and from 24 to 36 in case series. Conclusion: Establishing the diagnosis of PANDAS is complicated because of underlying comorbidities in the field of neurology-psychiatry and the lack of a reliable biomarker. The positive outcome after TE as reported in case studies may be influenced by the postoperative medication and is not supported by the results of large-scale studies. In the light of the considerable postoperative morbidity rate, it appears wise to indicate TE for PANDAS only in supervised clinical studies. PMID:28025607

Mitochondrial trifunctional protein (TFP) deficiency is an inherited metabolic disorder of mitochondrial fatty-acid oxidation. Isolated long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency is often reported in Caucasian countries due to a common mutation. However, the molecular and clinical basis of complete TFP deficiency has not been extensively reported. In this study, 14 Japanese cases (13 families) with complete TFP deficiency, including 9 previously reported cases, were analyzed to clarify the clinical and molecular characteristics of TFP deficiency. The clinical types of the 14 patients were as follows: 12 cases of neonatal (n=7) or myopathic (n=5) types and 2 cases of intermediate type. Peripheral neuropathy was found in four cases and hypocalcemia due to hypoparathyroidism, which is rarely reported in Caucasian patients, had developed in four cases. Maternal hemolysis, elevated liver enzymes and low platelet count syndrome and acute fatty liver of pregnancy were noted in two and one mothers, respectively. Fourteen mutations were identified in 26 alleles in Japanese patients, including two novel mutations (HADHA: c.361C>T, and HADHA-HADHB: g.26233880_ 26248855del), although no common mutations were found. This study suggests that the molecular and clinical aspects of Japanese patients with TFP deficiencies differ from those of Caucasian patients.

Until the 1980s, chrysotile asbestos was a component of automotive brakes manufactured in the US. The current OSHA Bulletin (2006) for brake repair cites a single study (Lemen, 2004) which concluded that the number of mesothelioma cases reported in the literature in "end-product users of friction materials" indicated an asbestos-related risk for auto mechanics. However, Lemen (2004) did not compare the reported number of cases to an "expected" value, even though pleural mesothelioma occurs in the general population in the absence of asbestos exposure. We compare the number of malignant pleural mesothelioma (MPM) cases reported in the US literature among auto mechanics between 1975-2007 to an expected value derived from estimated numbers of current and former auto mechanics. A total of 106 cases categorized as mesothelioma or malignant neoplasm of the pleura were found in the literature. Using background incidence rates for MPM of two and three cases per million individuals per year, we estimated that a range of 278-515 cases of non-asbestos-related MPM, respectively, would have occurred in current or former auto mechanics from 1975-2007. Our findings are consistent with the numerous epidemiology studies that have found no increased risk of MPM in auto mechanics. Copyright © 2012 Elsevier Inc. All rights reserved.

Estimating the extent of reporting to FDA: a case study of statin-associated rhabdomyolysis.

2008-03-01

To estimate the extent of reporting to FDA through statin-associated rhabdomyolysis data. Data included incidence rates (IRs) of hospitalized rhabdomyolysis among statin users from a population-based study, and comparable reported AERS cases and national estimates of statin use from an AERS analysis. Using IRs, national estimates of statin use and average days supply per prescription, we estimated the number of US statin-associated cases of hospitalized rhabdomyolysis. We compared this estimate to the observed number of cases reported to FDA to evaluate the extent of reporting. We repeated this method for atorvastatin, cerivastatin, pravastatin, and simvastatin and statin combinations. We performed sensitivity analyses to check for biases such as misclassification of statin use and cohort selection bias. We evaluated potential time-dependent cerivastatin reporting by a "Dear Health Care Provider (DHCP)" letter. The estimated extent of reporting to FDA varied by statin (atorvastatin, 5.0%; cerivastatin, 31.2%; simvastatin, 14.2%; all four combined, 17.7%; and non-cerivastatin statins combined, 9.9%). No pravastatin-associated cohort cases occurred. Across a reasonable value range, sensitivity analyses did not significantly alter the results; overall the cohort was similar to national statin-users. There was a large increase in AERS reports after the cerivastatin DHCP letter and the estimated extent of reporting increased from 14.8 to 35.0%. The extent of reporting of adverse events to FDA varied by statin and may be influenced by publicity. For statins-associated rhabdomyolysis, the estimated extent of reporting appears to range from 5 to 30% but in the absence of stimulated reporting appears to be 5-15%.

The chromosomal translocation t(14;18)(q32;q21) is commonly associated with neoplasms of follicular center cell origin and has also been reported in cases of chronic lymphocytic leukemia. However, T cell acute lymphoblastic (or lymphocytic) leukemia (T-ALL) with t(14;18)(q32;q21) has been rarely reported. Here, we report a case of myeloid antigen-positive T-ALL (My+T-ALL) with t(14;18)(q32;q21) and trisomy 10. This is the first reported case of My+T-ALL (L2) with such chromosomal abnormalities. Other published de novo ALL cases, with t(14;18)(q32;q21) and without a documented history of lymphoma, are summarized and reviewed in this report. The patient in this study was treated with remission induction therapy and intensive chemotherapy, followed by maintenance therapy. As of this writing, he has remained in remission for more than 3 years and has presented a better clinical outcome compared with other reported adult ALL patients with t(14;18)(q32;q21).

Excision of an enlarging vaginal epidermal inclusion cyst during pregnancy: a case report.

PubMed

Pereira, Nigel; Guilfoil, Daniel S

2012-07-01

The study aimed to report the case of a patient with an enlarging and symptomatic epidermal inclusion cyst during pregnancy that required surgical excision. This study was a case report of a 28-year-old woman (gravida 8, para 5, aborta 2) at a gestational age of 18 weeks 5 days who reported a tender vaginal mass that had grown larger for more than a week. An enlarging symptomatic cystic mass was surgically excised. Histopathologic findings of the excised mass were consistent with an epidermal inclusion cyst with surrounding moderate chronic inflammation and cyst rupture. The patient's symptoms resolved completely by her postoperative visit. Although most epithelial inclusion cysts are asymptomatic and can be managed expectantly, cysts that enlarge or become symptomatic should be excised surgically.

Murine or endemic typhus, caused by Rickettsia typhi, has been reported in all continents. In the 1970s, no cases of murine typhus were diagnosed in Tunisia. The clinico-epidemiological characteristics of seven cases of murine typhus diagnosed at our hospitals since 1993 are reported. Diagnosis was confirmed by indirect fluorescence assay detecting specific R. typhi antibodies. Murine typhus occurred in all ages from 18-80 years during the hot season in rural areas. Clinical features were: sudden onset of fever and absence of eschar in all cases, with maculo-papular rash (five cases), prostration (four cases), meningism (three cases) and pneumonia (four cases). Frequent laboratory findings were moderate thrombopenia (four cases) and elevated transaminases (four cases). Before the results of serology, clinical diagnoses were Mediterranean Spotted Fever (four cases), Q fever (one case), pneumonia (one case), and lymphocytic meningitis (one case). Serology confirmed all diagnoses with cross-reactivity with Rickettsia conorii. Murine typhus exists in Tunisia and its prevalence is underestimated. Further, more specific studies are needed to evaluate the true prevalence.

Case reports: Publication standards in forensic psychiatry.

PubMed

Hanson, Annette; Martinez, Richard; Candilis, Philip J

2014-01-01

Psychiatrists who publish case reports are required to seek informed consent from their subjects on the basis of the ethics-related obligation to maintain patient confidentiality. Academic journals have developed editorial standards to fulfill this obligation. Forensic evaluations do not create a doctor-patient relationship in the traditional sense, and information obtained through a forensic evaluation may also be found in the public domain. This public exposure is particularly likely, given the development of open access publishing standards, online journals, and increasing professional involvement in social media. This article outlines the ethics of informed consent in published case reports for general and forensic psychiatry and offers recommendations for forensic case study publishing. The authors suggest changes in the current requirements stated in The Journal for publication of case reports. © 2014 American Academy of Psychiatry and the Law.

Background Between April and June 2012, a reactive cholera vaccination campaign was conducted in Haiti using an oral inactivated bivalent whole-cell vaccine (BivWC). Methods We conducted a case-control study to estimate field effectiveness of the vaccine. Cases had acute watery diarrhea, sought treatment at one of three participating cholera treatment units from October 24, 2012 through March 9, 2014, and had a stool sample positive for cholera by culture. For each case, four controls (individuals who did not seek treatment for acute watery diarrhea) were matched by location of residence, calendar time, and age. We also conducted a bias-indicator case-control study to assess the likelihood of bias in the vaccine effectiveness (VE) study. Findings During the study period, 114 eligible individuals presented with acute watery diarrhea and were enrolled. 47 were analyzed as cases in the VE case-control study and 42 as cases in the bias-indicator study. In multivariable analyses, VE was 63% [95% confidence interval (CI): 8%–85%] by self-reported vaccination and 58% [95% CI: 13%–80%] for verified vaccination. Neither self-reported nor verified vaccination was significantly associated with non-cholera diarrhea (VE: 18% [95% CI: −208%–−78%] by self-report and −21% [95%CI: −238%–57%] for verified vaccination). Interpretation BivWC oral cholera vaccine was effective in protecting against cholera in Haiti during the study period –from 4 through 24 months after vaccination. Vaccination is an important component of epidemic cholera control efforts.

A critical assessment of the association between postnatal toxoplasmosis and epilepsy in immune-competent patients.

PubMed

Uzorka, J W; Arend, S M

2017-07-01

While postnatal toxoplasmosis in immune-competent patients is generally considered a self-limiting and mild illness, it has been associated with a variety of more severe clinical manifestations. The causal relation with some manifestations, e.g. myocarditis, has been microbiologically proven, but this is not unequivocally so for other reported associations, such as with epilepsy. We aimed to systematically assess causality between postnatal toxoplasmosis and epilepsy in immune-competent patients. A literature search was performed. The Bradford Hill criteria for causality were used to score selected articles for each component of causality. Using an arbitrary but defined scoring system, the maximal score was 15 points (13 for case reports). Of 704 articles, five case reports or series and five case-control studies were selected. The strongest evidence for a causal relation was provided by two case reports and one case-control study, with a maximal causality score of, respectively, 9/13, 10/13 and 10/15. The remaining studies had a median causality score of 7 (range 5-9). No selection bias was identified, but 6/10 studies contained potential confounders (it was unsure whether the infection was pre- or postnatal acquired, or immunodeficiency was not specifically excluded). Based on the evaluation of the available literature, although scanty and of limited quality, a causal relationship between postnatal toxoplasmosis and epilepsy seems possible. More definite proof requires further research, e.g. by performing Toxoplasma serology in all de novo epilepsy cases.

A researcher's review of adherence to forensic examination principles in homicide cases in Poland.

PubMed

Juszka, K; Juszka, K

The purpose of this paper is to verify adherence to forensic examination principles in homicide cases by analyzing the results of the author's own study of 90 court and prosecution cases from the period 2000-2010. The analyzed cases were sampled using the so-called multi-stage cluster sampling method, commonly used in social sciences in Poland. The cases were held in 17 organizational judiciary and prosecution units reporting to the Court of Appeal in Krakow and Appellate Prosecutor's Office in Krakow, respectively. The research tool was a questionnaire containing 40 relevant guidelines, covering both qualitative and quantitative features. In the 90 analyzed cases, a total of 251 forensic examination reports were prepared, including 110 site examination reports, 20 separate corpse examination reports, 29 personal examination reports and 92 object examination reports. The research aspects of forensic examinations will be analyzed from the perspective of adherence to the principles of conducting the same. As regards postulates de lege ferenda with respect to the implementation of forensic examination principles one should emphasize the need for using the appropriate form of description of corpse examination; the need for a more responsible attitude towards sealing off crime scenes and for recording information on sealing-off procedures in the examination report; the need for clear distinction of examination stages in drafting the examination report; the need for a detailed analysis of the examination carried out at its final stage at all times; the need for using professional vocabulary in all descriptions of examination activities in each case and the need for regular monitoring (by the person in charge of examination) also with regard to the tactical requirement to sign each sheet of the examination report. The tactical and procedural development of forensic examination principles, taking into account also the postulates de lege ferenda presented herein, will contribute to further development of forensic examination studies and will thus make examination a more common practice in criminal procedures.

Cotard's Syndrome is rare and no cases have been reported in pregnancy. We describe a case of a woman in the third trimester who attempted suicide by jumping out of a window, sustaining multiple fractures. Delivery of her baby by Caesarean section and orthopaedic intervention was necessary before electroconvulsive therapy (ECT) could be administered, resulting in a successful outcome for both mother and child.

To present a case of severe interstitial nephritis with proteinuria in primary Sjögren's syndrome (pSS) and review the literature regarding renal disease and its management in pSS, aiming to suggest recommendations for treatment. A search of MEDLINE (PubMed) was performed for review articles and case reports using the MESH terms: Sjögren syndrome; renal disease; interstitial nephritis (IN); glomerulonephritis (GN). We describe a rare case of pSS presenting with hypokalaemic tetraparesis and proteinuria due to severe IN, successfully treated with high-dose steroids and azathioprine. Reviewing the literature, we identified 180 reported cases of renal involvement in pSS (selected based on the European criteria for pSS), 89 of which underwent renal biopsies revealing IN in 49 cases, GN in 33 samples, and both IN and GN in seven. Eighteen studies reported treatment experience of renal disease in 32 pSS cases. Seventeen patients were treated with corticosteroids and cyclophosphamide, and 15 patients received only steroids with improvement in the majority of cases. The present case, as well as the limited number of reports in the literature, suggest that renal involvement, including IN, in pSS may improve with immunosuppressive therapy. Further studies are required to determine indications for and dosages of immunosuppressive treatment in patients with renal involvement of pSS.

Lupus anticoagulant, also known as lupus antibody, is generally associated with thrombosis rather than bleeding events. Lupus anticoagulant-hypoprothrombinemia syndrome in children is rather rare but can lead to mild to life-threatening bleeding. Here, we report 3 cases of lupus anticoagulant-hypoprothrombinemia syndrome associated with systemic lupus erythematosus. They initially presented with mucocutaneous bleedings, and subsequently developed other symptoms fulfilling the laboratory criteria for systemic lupus erythematosus. Case 2 and 3 had significant epistaxis and intracerebral hemorrhage responded to systemic corticosteroid along with fresh frozen plasma. Three cases demonstrated acquired hypoprothrombinemia with no correction of mixing studies. Case 1 had low factor X level, which has never been reported previously. In all 3 cases, their coagulogram returned to normal level after corticosteroid treatment.

Neurosyphilis in Africa: A systematic review

PubMed Central

Jarvis, Joseph N.; Howlett, William; Mabey, David C. W.

2017-01-01

Introduction Neurological involvement is one of the most important clinical manifestations of syphilis and neurological disease occurs in both early and late syphilis. The impact of HIV co-infection on clinical neurosyphilis remains unclear. The highest prevalence of both syphilis and HIV is in Africa. Therefore it might be expected that neurosyphilis would be an important and not uncommon manifestation of syphilis in Africa and frequently occur in association with HIV co-infection; yet few data are available on neurosyphilis in Africa. The aim of this study is to review data on neurosyphilis in Africa since the onset of the HIV epidemic. Methods We searched the literature for references on neurosyphilis in Africa for studies published between the 1st of January 1990 and 15th February 2017. We included case reports, case series, and retrospective and prospective cohort and case-control studies. We did not limit inclusion based on the diagnostic criteria used for neurosyphilis. For retrospective and prospective cohorts, we calculated the proportion of study participants who were diagnosed with neurosyphilis according to the individual study criteria. Depending on the study, we assessed the proportion of patients with syphilis found to have neurosyphilis, and the proportion of patients with neurological syndromes who had neurosyphilis. Due to heterogeneity of data no formal pooling of the data or meta-analysis was undertaken. Results Amongst patients presenting with a neurological syndrome, three studies of patients with meningitis were identified; neurosyphilis was consistently reported to cause approximately 3% of all cases. Three studies on stroke reported mixed findings but were limited due to the small number of patients undergoing CSF examination, whilst neurosyphilis continued to be reported as a common cause of dementia in studies from North Africa. Ten studies reported on cases of neurosyphilis amongst patients known to have syphilis. Studies from both North and Southern Africa continue to report cases of late stage syphilis, including tabes dorsalis and neurosyphilis, in association with ocular disease. Discussion This is the first systematic review of the literature on neurosyphilis in Africa since the beginning of the HIV epidemic. Neurosyphilis continues to be reported as a manifestation of both early and late syphilis, but the methodological quality of the majority of the included studies was poor. Future well-designed prospective studies are needed to better delineate the incidence and clinical spectrum of neurosyphilis in Africa and to better define interactions with HIV in this setting.

2005-01-01

BACKGROUND Ginkgo biloba (ginkgo) is a herbal remedy used by over 2% of the adult population in the United States. Several review articles have suggested that ginkgo may increase the risk of bleeding. OBJECTIVE To report a case of bleeding associated with using ginkgo, to systematically review the literature for similar case reports, and to evaluate whether using ginkgo is causally related to bleeding. DATA SOURCES We searched MEDLINE, EMBASE, IBIDS, and the Cochrane Collaboration Database from 1966 to October 2004 with no language restrictions. REVIEW METHODS Published case reports of bleeding events in persons using ginkgo were selected. Two reviewers independently abstracted a standard set of information to assess whether ginkgo caused the bleeding event. RESULTS Fifteen published case reports described a temporal association between using ginkgo and a bleeding event. Most cases involved serious medical conditions, including 8 episodes of intracranial bleeding. However, 13 of the case reports identified other risk factors for bleeding. Only 6 reports clearly described that ginkgo was stopped and that bleeding did not recur. Bleeding times, measured in 3 reports, were elevated when patients were taking ginkgo. CONCLUSION A structured assessment of published case reports suggests a possible causal association between using ginkgo and bleeding events. Given the widespread use of this herb and the serious nature of the reported events, further studies are needed. Patients using ginkgo, particularly those with known bleeding risks, should be counseled about a possible increase in bleeding risk. PMID:16050865

Chronic mastitis is a prolonged inflammatory breast disease, and little is known about its etiology. We identified 85 cases and 112 controls from 5 hospitals in Morocco and Egypt. Cases were women with chronic mastitis (including periductal, lobular, granulomatous, lymphocytic, and duct ectasia with mastitis). Controls had benign breast disease, including fibroadenoma, benign phyllodes, and adenosis. Both groups were identified from histopathologically diagnosed patients from 2008 to 2011, frequency-matched on age. Patient interviews elicited demographic, reproductive, breastfeeding, and clinical histories. Cases had higher parity than controls (OR = 1.75, 1.62–1.90) and more reported history of contraception use (OR = 2.73, 2.07–3.61). Cases were less likely to report wearing a bra (OR = 0.56, 0.47–0.67) and less often used both breasts for breastfeeding (OR = 4.40, 3.39–5.72). Chronic mastitis cases were significantly less likely to be employed outside home (OR = 0.71, 0.60–0.84) and more likely to report mice in their households (OR = 1.63, 1.36–1.97). This is the largest case-control study reported to date on risk factors for chronic mastitis. Our study highlights distinct reproductive risk factors for the disease. Future studies should further explore these factors and the possible immunological and susceptibility predisposing conditions. PMID:24327928

Use of Evidence-Based Decision-Making in Comprehensive Dental Treatment of a Patient with Meth Mouth-A Case Report.

This case report illustrates the use of evidence-based practice in formulating a comprehensive dental treatment plan for a patient who presented himself with signs of oral health debilitation accompanying methamphetamine (MA) abuse called "meth mouth" with the goal of providing dental care practitioners in Saudi Arabia with an insight into the global problem of MA abuse and its impact on oral health. This report documents the case of a 22-year-old male patient who reported to the clinic with rampant caries caused due to MA abuse exacerbated by poor oral hygiene and smoking habit. The treatment plan of this present case was formulated on the lines of the evidence-based dentistry approach. A clinical question was composed based on the Problem, Intervention, Comparison, and Outcome format to identify past studies and case reports on meth mouth. A standard search was conducted on PubMed Central. Standard guidelines on the treatment of meth mouth were extracted from the Web site of the American Dental Association. A total of 2 systematic reviews, 7 review articles, 4 epidemiologic studies, 5 case reports, and 1 American Dental Association guideline were found. Accelerated dental decay leading to rampant caries in young and middle-aged adults is a characteristic oral finding in MA abusers. The most important factor that affects the prognosis of dental care is complete cessation of MA use by the patient. Copyright © 2017 Elsevier Inc. All rights reserved.

Dental movement acceleration: Literature review by an alternative scientific evidence method

The aim of this study was to analyze the majority of publications using effective methods to speed up orthodontic treatment and determine which publications carry high evidence-based value. The literature published in Pubmed from 1984 to 2013 was reviewed, in addition to well-known reports that were not classified under this database. To facilitate evidence-based decision making, guidelines such as the Consolidation Standards of Reporting Trials, Preferred Reporting items for systematic Reviews and Meta-analyses, and Transparent Reporting of Evaluations with Non-randomized Designs check list were used. The studies were initially divided into three groups: local application of cell mediators, physical stimuli, and techniques that took advantage of the regional acceleration phenomena. The articles were classified according to their level of evidence using an alternative method for orthodontic scientific article classification. 1a: Systematic Reviews (SR) of randomized clinical trials (RCTs), 1b: Individual RCT, 2a: SR of cohort studies, 2b: Individual cohort study, controlled clinical trials and low quality RCT, 3a: SR of case-control studies, 3b: Individual case-control study, low quality cohort study and short time following split mouth designs. 4: Case-series, low quality case-control study and non-systematic review, and 5: Expert opinion. The highest level of evidence for each group was: (1) local application of cell mediators: the highest level of evidence corresponds to a 3B level in Prostaglandins and Vitamin D; (2) physical stimuli: vibratory forces and low level laser irradiation have evidence level 2b, Electrical current is classified as 3b evidence-based level, Pulsed Electromagnetic Field is placed on the 4th level on the evidence scale; and (3) regional acceleration phenomena related techniques: for corticotomy the majority of the reports belong to level 4. Piezocision, dentoalveolar distraction, alveocentesis, monocortical tooth dislocation and ligament distraction technique, only had case series or single report cases (4th level of evidence). Surgery first and periodontal distraction have 1 study at level 2b and corticision one report at level 5. Multiple orthodontic acceleration reports on humans were identified by an alternative evidence level scale, which is a simple and accurate way of determining which techniques are better and have a higher rate of effectiveness. The highest level of evidence for a specific procedure to accelerate orthodontic dental movement up to October 2013 was surgery first followed by low level laser application, corticotomy and periodontal distraction located on level 2, recommendation grade b from this proposed scientific evidence-based scale.

Between April and June, 2012, a reactive cholera vaccination campaign was done in Haiti with an oral inactivated bivalent whole-cell vaccine. We aimed to assess the effectiveness of the vaccine in a case-control study and to assess the likelihood of bias in that study in a bias-indicator study. Residents of Bocozel or Grand Saline who were eligible for the vaccination campaign (ie, age ≥12 months, not pregnant, and living in the region at the time of the vaccine campaign) were included. In the primary case-control study, cases had acute watery diarrhoea, sought treatment at one of three participating cholera treatment units, and had a stool sample positive for cholera by culture. For each case, four control individuals who did not seek treatment for acute watery diarrhoea were matched by location of residence, enrolment time (within 2 weeks of the case), and age (1-4 years, 5-15 years, and >15 years). Cases in the bias-indicator study were individuals with acute watery diarrhoea with a negative stool sample for cholera. Controls were selected in the same manner as in the primary case-control study. Trained staff used standard laboratory procedures to do rapid tests and stool cultures from study cases. Participants were interviewed to collect data on sociodemographic characteristics, risk factors for cholera, and self-reported vaccination. Data were analysed by conditional logistic regression, adjusting for matching factors. From Oct 24, 2012, to March 9, 2014, 114 eligible individuals presented with acute watery diarrhoea and were enrolled, 25 of whom were subsequently excluded. 47 participants were analysed as cases in the vaccine effectiveness case-control study and 42 as cases in the bias-indicator study. 33 (70%) of 47 cholera cases self-reported vaccination versus 167 (89%) of 188 controls (vaccine effectiveness 63%, 95% CI 8-85). 27 (57%) of 47 cases had certified vaccination versus 147 (78%) of 188 controls (vaccine effectiveness 58%, 13-80). Neither self-reported nor verified vaccination was significantly associated with non-cholera diarrhoea (vaccine effectiveness 18%, 95% CI -208 to 78 by self-report and -21%, -238 to 57 by verified vaccination). Bivalent whole-cell oral cholera vaccine effectively protected against cholera in Haiti from 4 months to 24 months after vaccination. Vaccination is an important component of efforts to control cholera epidemics.

To study the doping substances used in sport and their toxicity. Retrospective analysis from January 1992 to December 2000 of the cases of use of doping substances in sport reported by telephone to the anti-poison center in Marseilles. Fifty-one cases were reported concerning 48 men and 3 women with a mean age of 30, ranging from 10 to 55 years. Sixty-three percent of cases were reported over the last four years. The sport practiced was bodybuilding, except in 2 cases (cycling in one case and running in the other). The products used were mainly anabolizing hormones (15 times), clenbuterol (14 times) and creatine (7 times). A third of cases concerned associations of substances and 19 cases presented with symptomatology. The diversity in nature and status of the substances mentioned and their association requires enhanced vigilance with regard to the use of drugs in sport. The recent measures voted within the framework of the anti-doping law dated 23/3/99 are aimed at increasing surveillance with the development of anti-doping antennae.

Self versus proxy perspectives may produce different results that are important for clinical decision-making and for assessing outcomes in research studies. We examined differences in child versus parent report of the child's health-related quality of life (HRQOL) in a large prospective, community-based study of newly diagnosed childhood epilepsy that included children with epilepsy (case) and sibling controls. HRQOL was assessed 8 to 9 years after initial diagnosis of epilepsy in a subset of 143 case-control matched pairs using the Child Health Questionnaire (CHQ), a generic HRQOL measure with child (CHQ-CF87), and parent (CHQ-PF50) versions. There were no significant differences between self-reported case and sibling control HRQOL scores on 9 of 11 scales or 2 global items. Nevertheless, parent ratings were significantly better (higher HRQOL) for sibling controls compared with epilepsy cases on 10 of 12 scales, global behavior and general health items, and the physical and psychosocial summary scores (P≤0.05). Parent-child agreement was low for cases and controls (kappa 0.27-0.33) for three single-item questions with the same wording on parent and child versions. Parent ratings of the case's HRQOL were often significantly associated with 5-year remission status and current antiepileptic drug use, but the case's self-reported HRQOL scores were not. In contrast, current pharmacoresistance was often associated with the child and parent ratings of the child's HRQOL. Children with epilepsy report HRQOL that is comparable to that of sibling controls, while parents rate children with epilepsy as having lower HRQOL than sibling controls. Measuring outcomes in studies of this population should incorporate both perspectives. © 2010, International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

The objective of this retrospective study was to examine the discrepancy between information derived from written medical reports and the results of forensic DNA analyses on swabs collected from the victims in 122 cases of alleged sexual assault treated at the Emergency Department of Padua Hospital. The examination of discrepant results has proved useful to support a broader application of sexual assault management, particularly during the taking of case history. The Laboratory of Forensic Genetics of Padua University have processed samples from 122 sexual assault cases over a period of 5 years. Of the 103 cases in which the victim reported a penetration and ejaculation, only 67 (55% of all the samples) correlated with positive feedback match from the laboratory. In 36 cases in which the patient reported penetration with ejaculation, no male DNA was found in the samples collected. Therefore, there was a total of 41 cases in which the patient's report were not supported by laboratory data. In the remaining ten cases, which had an ambiguous history, 3 tested positively for the presence of male DNA. To avoid discrepancies between the medical reporting and reconstruction of sex crimes, it is crucial to deploy strategies which focus not only on the technical aspects of evidence collection, but also on how the victim's story is recorded; such efforts could lead to better management of sexual assault victims, and to a strengthened legal impact of forensic evidence and of crime reconstruction.

A new, recently issued national law and regulation in China conferred the responsibility of healthcare professionals in child maltreatment intervention. However, few studies have reported on the recognition and reporting of child maltreatment by healthcare professionals in China. The aim of this study was to assess healthcare professionals' knowledge, attitudes, and self-perceived behaviour in terms of identifying, assessing, and reporting child maltreatment cases in China. A cross-sectional survey of 877 healthcare professionals from four provinces was conducted using a structured questionnaire. The respondents demonstrated insufficient knowledge on identifying potential child maltreatment cases. Over 30% of them were less than confident in the medical examination, evaluation, and treatment of child maltreatment cases, especially with regard to cases involving sexual abuse. Only 3.19% of respondents had ever received training on child maltreatment intervention, and as a result, lack of knowledge with regard to dealing with child maltreatment cases, referral procedures, and regulations was indicated to be the main cause of underreporting. Healthcare professionals in China have insufficient knowledge, skills, and confidence when it comes to dealing with all aspects of child maltreatment. Although participants reported a positive attitude towards their role in detecting and reporting child maltreatment cases, there are obstacles that hinder them from doing so. Appropriate training courses should be developed to empower professionals with knowledge and skills, as well as increase their confidence in dealing with suspected child maltreatment cases. © 2017 John Wiley & Sons Ltd.

Adefovir dipivoxil (ADV) is one of the commonly used antiviral agents in the treatment of chronic hepatitis B (CHB) infection. Safety of a daily dose of 10 mg ADV is advocated by the registration trials. We report a case of severe hypophosphatemic osteomalacia and renal Fanconi syndrome induced by low-dose ADV in a CHB-related cirrhosis patient, and discuss the case through a thorough review of other cases reported in the literature. A 48-yr-old Chinese man with CHB-related cirrhosis developed severe progressive generalized bone pain and muscle weakness after receiving ADV 10 mg daily for 54 months. The laboratory results showed severe hypophosphatemia and features of proximal renal tubule dysfunction. Imaging studies were consistent with osteomalacia. After discontinuation of ADV, his symptoms resolved, laboratory abnormalities normalized and imaging studies showed improvement. In addition to our case, 12 other patients have been reported to have developed hypophosphatemic osteomalacia induced by low-dose ADV. Most of the reported cases were of subjects of East-Asian ethnicity. After discontinuation or reduction of ADV, serum phosphate level increased and clinical symptoms significantly improved in all cases. Hypophosphatemic osteomalacia and renal Fanconi syndrome can be associated with low-dose ADV. Clinicians treating CHB patients with ADV 10 mg daily over long periods of time should be aware of this infrequent but serious complication. © 2013 John Wiley & Sons Ltd.

Case reports: Should we do away with them?

There has been a gradual decline in the number of case reports published in leading medical journals in recent years. Since case reports are not highly cited they have an adverse effect on the journal impact factor. On the other hand sharing new experiences, challenges, or discoveries with colleagues is essential for medical community. Should case reports be eliminated from the journals or published only in journals devoted to case reports? Observational study. Web of Science database was searched, between 2005 and 2009, with terms: "anesthesia", "anesthesiology" and "case report" yielding 25 969, 9532, and 661 publications, respectively. Since some reports contained large number of cases, only those involving up to three cases (n = 425) were evaluated by the authors with respect to their type, contribution to knowledge and/or practice (Likert scale) and times they were cited. Distribution of answers to the statement "Case has added to my knowledge and/or improved my practice" was; 3% (strongly disagree), 10.5% (disagree), 33.2% (neither agree nor disagree), 39.3% (agree) and 13.7% (strongly agree). Average citations per item was 4.43 (1883/425), 7.32 (4838/661), and 7.82 (74 529/9532). As to the types of the reports; 50% unexpected event in the course of anesthesia, 31% unusual and instructive cases, 9.6% novel/unique anesthetic techniques, 6% novel use of equipment, 1.6% new information on diseases of importance to anesthesiology and 1% scientific observations. Case reports have been an important source of clinical guidance and scientific insight, and play an important role in medical education. They can be published quickly, providing publication opportunity for juniors and for clinicians who may not have the time or finance to conduct large-scale research. On the other hand some argue, that case reports are irrelevant in current medical practice and education, being at the bottom of the hierarchical ladder of medical evidence. We conclude that case reports should not be done away with but be published in websites and journals like the venue to be launched in 2013 by the International Anesthesia Research Society, devoted entirely to them to meet the need for the publication of interesting cases.

Background The use of a statistical approach to analyze cumulative adverse event (AE) reports has been encouraged by regulatory authorities. However, data variations affect statistical analyses (eg, signal detection). Further, differences in regulations, social issues, and health care systems can cause variations in AE data. The present study examined similarities and differences between two publicly available databases, ie, the Japanese Adverse Drug Event Report (JADER) database and the US Food and Drug Administration Adverse Event Reporting System (FAERS), and how they affect signal detection. Methods Two AE data sources from 2010 were examined, ie, JADER cases (JP) and Japanese cases extracted from the FAERS (FAERS-JP). Three methods for signals of disproportionate reporting, ie, the reporting odds ratio, Bayesian confidence propagation neural network, and Gamma Poisson Shrinker (GPS), were used on drug-event combinations for three substances frequently recorded in both systems. Results The two databases showed similar elements of AE reports, but no option was provided for a shareable case identifier. The average number of AEs per case was 1.6±1.3 (maximum 37) in the JP and 3.3±3.5 (maximum 62) in the FAERS-JP. Between 5% and 57% of all AEs were signaled by three quantitative methods for etanercept, infliximab, and paroxetine. Signals identified by GPS for the JP and FAERS-JP, as referenced by Japanese labeling, showed higher positive sensitivity than was expected. Conclusion The FAERS-JP was different from the JADER. Signals derived from both datasets identified different results, but shared certain signals. Discrepancies in type of AEs, drugs reported, and average number of AEs per case were potential contributing factors. This study will help those concerned with pharmacovigilance better understand the use and pitfalls of using spontaneous AE data. PMID:26109846

Abstract The aim of the study was to compare self-reported and analytically confirmed substance use in cases of acute recreational drug toxicity. We performed a retrospective analysis of emergency department presentations of acute recreational drug toxicity over 2 years (October 2013 to September 2015) within the European Drug Emergencies Network Plus project. Among the 10,956 cases of acute recreational drug toxicity during the study period, 831 could be included. Between the self-reported substance use and the toxicological results, the highest agreement was found for heroin (86.1%) and cocaine (74.1%), whereas inhalants, poppers, and magic mushrooms were self-reported but not analytically detected. Cathinones and other new psychoactive substances (NPS) could be detected using additional analytical methods. Among cases with both immunoassay (IA) and confirmation with mass spectrometry (MS), the results were consistent for methadone (100%) and cocaine (95.5%) and less consistent for amphetamines (81.8%). In cases with a positive IA for amphetamines (n = 54), MS confirmed the presence of 3,4-methylenedioxymethamphetamine (MDMA), amphetamine, methamphetamine, and NPS in 37, 20, 10, and 6 cases, respectively, also revealing use of more than 1 substance in some cases. MS yielded positive results in 21 cases with a negative IA for amphetamines, including amphetamine, MDMA, methamphetamine, and NPS, in 14, 7, 2, and 2 cases, respectively. In conclusion, the highest agreement was found between self-reports and analytical findings for heroin and cocaine. The diagnosis of NPS use was mainly based on self-report. The IAs accurately identified methadone and cocaine, and MS had advantages for the detection of NPS and amphetamine derivatives. PMID:29384873

Femoral neuropathy due to patellar dislocation in a theatrical and jazz dancer: a case report.

PubMed

Shin, Chris S; Davis, Brian A

2005-06-01

This case report describes a teenage female, high-level modern dancer who suffered multiple left patellar dislocations. Her history is atypical in that after her fifth dislocation, her recovery was hindered secondary to persistent weakness and atrophy of her quadriceps out of proportion to disuse alone. Electrodiagnostic studies and magnetic resonance imaging showed evidence of a subacute femoral neuropathy correlating chronologically with her most recent patellar dislocation. This case suggests that further diagnostic study may be warranted in patients with persistent quadriceps weakness or atrophy after a patellar dislocation, because this may suggest the presence of a femoral neuropathy. This is important because the strength training goals and precautions differ in disuse atrophy and a neuropathy. We believe this is the first reported case of a femoral neuropathy associated with the mechanism of a patellar dislocation.

In 1992 surveillance of acute flaccid paralysis (AFP) cases was introduced in Malaysia along with the establishment of a national referral laboratory at the Institute for Medical Research. The objective of this study was to determine the incidence, viral etiology and clinical picture of AFP cases below 15 years of age, reported from 2002 to 2007. Six hundred seventy-eight of 688 reported cases were confirmed as AFP by expert review. The clinical presentation of acute flaccid paralysis in these cases was diverse, the most commonly reported being Guillian-Barre syndrome (32.3%). Sixty-nine viruses were isolated in this study. They were Sabin poliovirus (25), Echovirus (22), Cocksackie B (11), EV71 (5), Cocksackie A (1), and untypable (5). Malaysia has been confirmed as free from wild polio since the surveillance was established.

Neuraxial blocks and spinal haematoma: Review of 166 case reports published 1994-2015. Part 1: Demographics and risk-factors.

PubMed

Lagerkranser, Michael

2017-04-01

Bleeding into the vertebral canal causing a spinal haematoma (SH) is a rare but serious complication to central neuraxial blocks (CNB). Of all serious complications to CNBs such as meningitis, abscess, cardiovascular collapse, and nerve injury, neurological injury associated with SH has the worst prognosis for permanent harm. Around the turn of the millennium, the first guidelines were published that aimed to reduce the risk of this complication. These guidelines are based on known risk factors for SH, rather than evidence from randomised, controlled trials (RCTs). RCTs, and therefore meta-analysis of RCTs, are not appropriate for identifying rare events. Analysing published case reports of rare complications may at least reveal risk factors and can thereby improve management of CNBs. The aims of the present review were to analyse case reports of SH after CNBs published between 1994 and 2015, and compare these with previous reviews of case reports. MEDLINE and EMBASE were used for identifying case reports published in English, German, or Scandinavian languages, using appropriate search terms. Reference lists were also scrutinised for case reports. Twenty different variables from each case were specifically searched for and filled out on an Excel spreadsheet, and incidences were calculated using the number of informative reports as denominator for each variable. Altogether 166 case reports on spinal haematoma after CNB published during the years between 1994 and 2015 were collected. The annual number of case reports published during this period almost trebled compared with the two preceding decades. This trend continued even after the first guidelines on safe practice of CNBs appeared around year 2000, although more cases complied with such guidelines during the second half of the observation period (2005-2015) than during the first half. Three types of risk factors dominated: (1) Patient-related risk factors such as haemostatic and spinal disorders, (2) CNB-procedure-related risks such as complicated block, (3) Drug-related risks, i.e. medication with antihaemostatic drugs. The annual number of published cases of spinal haematoma after central neuraxial blocks increased during the last two decades (1994-2015) compared to previous decades. Case reports on elderly women account for this increase. Antihaemostatic drugs, heparins in particular, are still major risk factors for developing post-CNB spinal bleedings. Other risk factors are haemostatic and spinal disorders and complicated blocks, especially "bloody taps", whereas multiple attempts do not seem to increase the risk of bleeding. In a large number of cases, no risk factor was reported. Guidelines issued around the turn of the century do not seem to have affected the number of published reports. In most cases, guidelines were followed, especially during the second half of the study period. Thus, although guidelines reduce the risk of a post-CNB spinal haematoma, and should be strictly adhered to in every single case, they are no guarantee against such bleedings to occur.

Summary Hypothyroidism is a wide clinical spectrum disorder and only a few cases in literature show this. Rhabdomyolysis and acute renal impairment can be seen concurrently in a hypothyroid state. We report a case of severe hypothyroidism with poor drug compliance leading to rhabdomyolysis and acute kidney injury. Learning points: Hypothyroidism is a rare cause of acute kidney injury. In this case report, we studied a rare occurrence of acute renal impairment due to hypothyroidism with poor drug compliance, which induced rhabdomyolysis. Our report emphasized that thyroid status should be evaluated in patients with unexplained acute renal impairment or presenting with the symptoms of muscle involvement. PMID:27855234

Lyme disease (LD) is the most common vector-borne disease in Ontario, Canada. We describe the epidemiology and clinical manifestations of LD in Ontario and examine trends in the incidence of non-disseminated and disseminated LD. LD surveillance data from the integrated Public Health Information System (iPHIS) from 2005–2014 were mapped to symptoms according to syndrome groups (erythema migrans (EM), flu-like, cardiac, neurologic or arthritic) and disease stages (early localized, early disseminated or late disseminated). During the study period, 1,230 cases due to Borrelia burgdoferi were reported in Ontario with annual incidence rates ranging from 0.32 (2006) to 2.16 (2013) cases per 100,000 population. Seventy percent of cases had EM and the proportion of cases with EM increased over time. Other clinical manifestations included flu-like (75%), arthritic (42%), neurologic (41%) and cardiac (6%) symptoms. Early localized disease (n = 415) manifested with EM (87%) and flu-like (57%) symptoms; early disseminated disease (n = 216) manifested with neurologic (94%), cardiac (10%) and EM (63%) symptoms; and late disseminated disease (n = 475) manifested with EM (62%), neurologic (55%), cardiac (9%), and arthritic symptoms (i.e., arthralgia (93%) and arthritis (7%)). Early localized and early disseminated cases (88% each) occurred primarily from May through September, compared to late disseminated cases (81%). The proportion of cases reported to public health within 30 days of illness onset increased during the study period, while the proportion of cases reported within 1–3 months and >3 months decreased. Geographical variations characterized by higher incidence of early localized disease and earlier public health notification (within 30 days of illness onset) occurred in regions with established or recently established LD risk areas, while later public health notification (>3 months after illness onset) was reported more frequently in regions with recently established or no identified risk areas. This is the first study to describe the clinical manifestations of LD in Ontario, Canada. The observed geographical variations in the epidemiology of LD in Ontario reinforce the need for regionally focused public health strategies aimed at increasing awareness, promoting earlier recognition and reporting, and encouraging greater uptake of preventive measures.

Port-site metastases (PSMs) are well-known potential complications of laparoscopic surgery for gynaecologic malignancies. The present case study reports PSM following laparoscopic surgery for Stage IA Grade 1 endometrioid endometrial cancer (EEC). The recurrence developed within 7 months following primary surgery and required surgical excision followed by adjuvant chemo-radio therapy. After 9 months, the patient remains disease-free. PSMs are rare complications following laparoscopic surgery. Amongst the 23 cases of endometrial cancer PSMs reported so far, only 4 followed EEC Stage IA Grade 1-2. The present study reports a rare case of PSM after Stage IA Grade 1 EEC. The clinical and prognostic relevance of PSMs has not been identified so far; and it is not known whether PSMs represent a local recurrence or a systemic recurrence. Surgeons should be aware that even low-risk EEC may be followed by PSMs and should take steps to prevent these rare recurrences.

During the past 33 months, thrombolysis of 79 clotted hemodialysis shunts was attempted by injecting small quantities of dilute streptokinase solution directly into the clotted shunt, followed by massage of the clot. Embolization of clot fragments in six of 79 cases (7.6%) was demonstrated angiographically. In four of the six cases embolization involved the brachial artery or its branches. In one case embolization involved an arm vein, and in one case embolization involved both the bracial artery and axillary vein. All patients remained asymptomatic, and repeat angiographic study, usually performed the following day, showed resolution of the emboli in fourmore » of five cases. The incidence of embolization in direct-injection thrombolysis reported in this study appears to be comparable to that reported in studies using the streptokinase infusion technique.« less

Parent-child incest that extends into adulthood: a survey of international press reports, 2007-2011.

PubMed

Middleton, Warwick

2013-01-01

Although the subject of ongoing incestuous abuse during adulthood has never been addressed in a systematic way in the professional literature, accounts of such cases have been appearing for many years. The Josef Fritzl case added a new impetus to reporting such abuses in the popular press. The current study presents 44 such cases from 24 countries that appeared in English-language press accounts over 5 years commencing January 2007. These cases are discussed in light of the minimal coverage of such issues in the professional literature. The results of this study suggest that cases of enduring incest are not rare and typically incorporate decades of sexual abuse, frequently result in pregnancies, and commonly incorporate ongoing violence and death threats.

Lipomatous hemangiopericytoma in a child: A case report with immunohistochemical evaluation

Madala, Jayakiran; Guttikonda, Venkateswara Rao; Korlepara, Rajani

2015-01-01

Lipomatous hemangiopericytomas are rare soft-tissue tumors that show areas of hemangiopericytoma like vascular pattern admixed with lipid containing cells. It is now considered a subtype of solitary fibrous tumor due to histopathological and immunohistochemical similarities. To date, only a few cases have been adequately reported in the medical literature. A case of lipomatous hemangiopericytoma in an 11-year-old female patient is presented and the clinical, histopathological and immunohistochemical features are discussed, along with a literature review. To the best of our knowledge, this is the first known case of a lipomatous hemangiopericytoma in a pediatric patient. Our case report further emphasizes that a number of studies should be evaluated to delineate hemangiopericytomas from solitary fibrous tumors. PMID:26097315

Self-reported shift work, recall bias, and belief about disease causation in a case-control study of breast cancer.

2017-10-01

Recall bias is a potential source of misclassification in case-control studies. Studies have shown that the association between exposure and disease can differ according to participants' beliefs or knowledge about the effect of that exposure on disease. We investigated the association between belief about breast cancer causation and self-reported shift work exposure in a case-control study. Women completed a questionnaire asking whether they believed that shift work caused cancer either before or after reporting their history of shift work. We measured: whether belief modified the association between reported shift work and disease; whether belief was associated with reported shift work exposure; and whether being prompted to recall shift work exposure was associated with an increased likelihood of believing that shift work increased breast cancer risk. There was a significant association between believing shift work increased breast cancer risk and reporting exposure to shift work. Being prompted to recall shift work was not associated with a belief that shift work increased risk. The association between pre-existing belief about breast cancer risk and reported shift work is likely to be due to exposed individuals believing that exposure increases risk, rather than resulting from recall bias.

Local brain herniation after removal of chronic subdural haematoma is extremely rare, especially in adult patients. This study reports a case of local brain herniation after partial membranectomy for organized chronic subdural haematoma. A 77-year-old man presented with dysarthria and dysphasia caused by local brain herniation of the right frontal lobe through a defect of the inner membrane. The herniated brain was detected by magnetic resonance (MR) imaging. The patient underwent a craniotomy to release the herniated and strangulated brain, which were consistent with the MR imaging findings. The patient recovered fully within 1 month after surgery. To date, five cases of brain herniation through the internal subdural membrane have been reported as complications of chronic subdural haematomas. All but one case occurred in the paediatric population. Urgent surgery should be performed, even if an adult patient suffers from local brain herniation, for preservation of brain function. This is the sixth reported case of brain herniation through a defect of the inner membrane and the second reported case in the adult population.

Background Countries in the different stages of pre-elimination, elimination, and prevention of reintroduction are required to report the number of indigenous and imported malaria cases to the World Health Organization (WHO). However, these data have not been systematically analysed at the global level. Objective For the period 2007 to 2013, we aimed to report on 1) the proportion of countries providing data on the origin of malaria cases and 2) the origin of malaria cases in countries classified as being in the stages of pre-elimination, elimination and prevention of reintroduction. Design An observational study using annual data reported through routine health information systems to the WHO Global Malaria Programme between 2007 and 2013. Results For all countries classified as being in pre-elimination, elimination, and prevention of reintroduction in the year 2013, there has been a substantial decrease in the total number of indigenous malaria cases, from more than 15,000 cases reported in 2007 to less than 4,000 cases reported in 2013. However, the total number of imported malaria cases has increased over that time period, from 5,600 imported cases in 2007 to approximately 6,800 in 2013. Conclusions Vigilant monitoring of the numbers of imported and indigenous malaria cases at national and global levels as well as appropriate strategies to target these cases will be critical to achieve malaria eradication.

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

Adherence undeniably impacts product effectiveness in microbicide trials, but the connection has proven challenging to quantify using routinely collected behavioral data. We explored this relationship using a nested case-control study in the CAPRISA 004 Tenofovir (TFV) gel HIV prevention trial. Detailed 3-month recall data on sex events, condom and gel use were collected from 72 incident cases and 205 uninfected controls. We then assessed how the relationship between self-reported adherence and HIV acquisition differed between the TFV and placebo gel groups, an interaction effect that should exist if effectiveness increases with adherence. The CAPRISA 004 trial determined that randomization to TFV gel was associated with a significant reduction in risk of HIV acquisition. In our nested case-control study, however, we did not observe a meaningful decrease in the relative odds of infection-TFV versus placebo-as self-reported adherence increased. To the contrary, exploratory sub-group analysis of the case-control data identified greater evidence for a protective effect of TFV gel among participants reporting less than 80 % adherence to the protocol-defined regimen (odds ratio (OR) 0.30; 95 % CI 0.11-0.78) than among those reporting ≥ 80 % adherence (Odds Ratio 0.81; 95 % CI 0.34-1.92). The small number of cases may have inhibited our ability to detect the hypothesized interaction between adherence and effectiveness. Nonetheless, our results re-emphasize the challenges faced by investigators when adherence may be miss-measured, miss-reported, or confounded with the risk of HIV.

The estimated incidence of acute promyelocytic leukemia (APL) is approximately 6 cases per 10 million people per year with no apparent differences between sexes. The age of APL cases is younger than that of other acute myeloid leukemias (AML). Spatial and temporal clusters of APL have been reported. These observations suggest a possible selective role for environmental and/or occupational factors in APL development. A multicenter case-control study was carried out on risk factors for acute leukemias and preleukemias. In this report data related to APL are selectively analyzed from the larger study to identify specific risk factors. The case-control study on 38 cases of APL showed a strong association with shoemaking (odds ration 6.3, 95% confidence interval 1.3-31.1). A moderate leukemogenic effect from living in houses built with tuff, a polous building material containing gamma-emitting radionuclides and having a high radon concentration, and from using hair dyes was also suggested. These data, together with the reported spatial and temporal clustering of APL, support the hypothesis of specific environmental and/or occupational risk factors for APL among other AML subtypes and indicate the need for additional ad hoc multicenter studies.

The current study aims to assess the preventability of the contrast media adverse drug reactions reported through the Campania spontaneous reporting system, identifying the possible limitations emerged in this type of evaluation. All the individual case safety reports validated by the Campania Pharmacovigilance Regional Centre from July 2012 to September 2015 were screened to select those that reported contrast media as suspected drug. Campania Preventability Assessment Committee, in collaboration with clinicians specialized in Radiology, assessed the preventability according to the P-Method, through a case-by-case approach. From July 2012 to September 2015, 13798 cases were inserted by pharmacovigilance managers in the Italian Pharmacovigilance Network database (in the geographical contest of the Campania Region), of which 67 reported contrast media as suspected drug. Five preventable cases were found. The most reported causes for preventability were the inappropriate drug use for the case clinical conditions and the absence of the preventive measure administrated prior to the contrast media administration. Several limitations were found in the evaluation of the critical criteria for the preventability assessment. Educational initiatives will be organized directly to the healthcare professionals involved in the contrast media administration, to promote an appropriate use of the contrast media.

Neurological complications of scrub typhus are reported to be rare. Peripheral nervous system involvement has been reported in only one case. We present two cases of Guillan-Barré syndrome (GBS) associated with scrub typhus. In both cases, the findings of an elevated indirect immunofluorescent antibody titer for Orientia tsutsugamushi and nerve conduction study showing sensory-motor polyneuropathy, have led us to believe that scrub typhus could be one of the antecedent illnesses associated with GBS.

Neonaticides following "secret" pregnancies: seven case reports.

PubMed Central

Saunders, E

1989-01-01

Seven neonaticides were reported during a 14-month period in the State of Iowa. This is an alarming number considering that only one such case was reported in the previous year. The majority of cases involved the birth of a live infant to an adolescent who had reportedly kept her pregnancy secret from family and friends. The death of the infants resulted from exposure or drowning. Efforts were made by the mother to hide or dispose of her infant's body. Basic information about each of the reported cases is presented, as well as the sentences given the adult mothers charged with the crime of child endangerment. The dynamics of these cases are reviewed in the context of earlier studies dealing with the phenomenon of neonaticide. Infanticide has deep roots in several cultures. It was practiced in some primitive societies and was decreed a capital offense as early as 1643. Its occurrence recently prompts suggestions for activities by professionals to prevent these tragedies. More research and further attention to this problem is warranted. PMID:2502808

A case of misdiagnosis of mild cognitive impairment: The utility of symptom validity testing in an outpatient memory clinic.

PubMed

Roor, Jeroen J; Dandachi-FitzGerald, Brechje; Ponds, Rudolf W H M

2016-01-01

Noncredible symptom reports hinder the diagnostic process. This fact is especially the case for medical conditions that rely on subjective report of symptoms instead of objective measures. Mild cognitive impairment (MCI) primarily relies on subjective report, which makes it potentially susceptible to erroneous diagnosis. In this case report, we describe a 59-year-old female patient diagnosed with MCI 10 years previously. The patient was referred to the neurology department for reexamination by her general practitioner because of cognitive complaints and persistent fatigue. This case study used information from the medical file, a new magnetic resonance imaging brain scan, and neuropsychological assessment. Current neuropsychological assessment, including symptom validity tests, clearly indicated noncredible test performance, thereby invalidating the obtained neuropsychological test data. We conclude that a blind spot for noncredible symptom reports existed in the previous diagnostic assessments. This case highlights the usefulness of formal symptom validity testing in the diagnostic assessment of MCI.

Hearing impairment associated with oral terbinafine use: a case series and case/non-case analysis in the Netherlands Pharmacovigilance Centre Lareb database and VigiBase™.

2012-08-01

The Netherlands Pharmacovigilance Centre Lareb received reports of six cases of hearing impairment in association with oral terbinafine use. This study describes these cases and provides support for this association from the Lareb database for spontaneous adverse drug reaction (ADR) reporting and from Vigibase™, the ADR database of the WHO Collaborating Centre for International Drug Monitoring, the Uppsala Monitoring Centre. The objective of the current study was to identify whether the observed association between oral terbinafine use and hearing impairment, based on cases received by Lareb, constitutes a safety signal. Cases of hearing impairment in oral terbinafine users are described. In a case/non-case analysis, the strength of the association in Vigibase™ and the Lareb database was determined (date of analysis August 2011) by calculating the reporting odds ratios (RORs), adjusted for possible confounding by age, sex and ototoxic concomitant medication. For the purpose of this study, RORs were calculated for deafness, hypoacusis and the combination of both, defined as hearing impairment. In the Lareb database, six reports concerning individuals aged 31-82 years, who developed hearing impairment after starting oral terbinafine, were present. The use of oral terbinafine was disproportionally associated with hypoacusis in both the Lareb database (adjusted ROR 3.9; 95% CI 1.7, 9.0) and in Vigibase™ (adjusted ROR 1.7; 95% CI 1.0, 2.8). Deafness was not disproportionally present in either of the databases. Based on the described cases and the statistical analyses from both databases, a causal relationship between the use of oral terbinafine and hearing impairment is possible. The mechanism by which terbinafine could cause hearing impairment has not been elucidated yet. The pharmacological action of terbinafine is based on the inhibition of squalene epoxidase, an enzyme present in both fungal and human cells. This inhibition might result in a decrease in cholesterol levels in human cells, among which are the outer hair cells of the cochlea. It may be possible that the reduction in cochlear cholesterol levels leads to impaired cochlear function and possibly hearing impairment. In this study we describe hearing impairment as a possible ADR of oral terbinafine, based on six case reports and statistical support from Vigibase™ and the Lareb database. To our knowledge this association has not been described before.

The lethality of malaria in the extra-Amazonian region is more than 70 times higher than in Amazonia itself. Recently, several studies have shown that autochthonous malaria is not a rare event in the Brazilian southeastern states in the Atlantic Forest biome. Information about autochthonous malaria in the state of Rio de Janeiro (RJ) is scarce. This study aims to assess malaria cases reported to the Health Surveillance System of the State of Rio de Janeiro between 2000-2010. An average of 90 cases per year had parasitological malaria confirmation by thick smear. The number of malaria notifications due to Plasmodium falciparum increased over time. Imported cases reported during the period studied were spread among 51% of the municipalities (counties) of the state. Only 35 cases (4.3%) were autochthonous, which represents an average of 3.8 new cases per year. Eleven municipalities reported autochthonous cases; within these, six could be characterised as areas of residual or new foci of malaria from the Atlantic Forest system. The other 28 municipalities could become receptive for transmission reintroduction. Cases occurred during all periods of the year, but 62.9% of cases were in the first semester of each year. Assessing vulnerability and receptivity conditions and vector ecology is imperative to establish the real risk of malaria reintroduction in RJ. PMID:25185004

To describe the socio-demographic along with the medico-legal characteristics of rape victims reporting to a female police station of Lahore. Observational study. Female Police Station in Shadman, Lahore, from, June 1995 to January 2009. A total of 74 cases of alleged rape victims were identified while reviewing all available police files concerning reported rapes and attempted rapes from 1995 to 2008. The data was gathered on preformed questionnaires after conducting the pilot study. All information about victims and alleged offenders were extracted from the police files including socio-demographic profile of the accused and victim both. Use of weapon, evidence of physical and genital trauma, assailant identification and his relationship with the victim, number of accused persons and location of rape was noted in each case. Examination by doctor and obtaining the specimens were also identified and was related to the outcome of the court case. Chi-square test was applied to determine the association of rape with age and educational status of the victim and the accused. A total of 74 cases of alleged rape were reported in the study period at Shadman Female Police Station. Maximum number of victims was reported in the age group 10-19 years (n=46, 62.2%). Majority of the accused belonged to 20-39 years' age group constituting 64.8% of the total. Regarding educational status 45 (60.8%) of the victims and 51 (68.9%) of the accused were illiterate. Significant association was found between the educational status of rape victims and accused (p = 0.016) but not between their ages (p = 0.862). The maximum incidence of rape was reported in unmarried (n = 55, 74.3%) and unemployed (n =61, 82.4%) women. In 14 cases (19%) use of weapon was reported. Physical trauma was reported in 29 (39%) and genital trauma in 14 (19%) cases. The accused were identified as family friends (25%) and neighbours (23%) respectively. Only 21% of the victims were examined by doctor and specimens were obtained in only 14.9% of the cases. Acquittal of the accused was observed in 43% of the cases while 34% cases were still pending; conviction of the accused was observed in only 5% of the cases. Rape victims usually belong to young age group between 10-19 years majority of being unmarried and unemployed. Only a smaller fraction of the victims were examined by doctor and specimens were obtained in only few of the cases.

2012-01-01

Background A prospective study of diet and cancer has not been conducted in India; consequently, little is known regarding follow-up rates or the completeness and accuracy of cancer case ascertainment. Methods We assessed follow-up in the India Health Study (IHS; 4,671 participants aged 35–69 residing in New Delhi, Mumbai, or Trivandrum). We evaluated the impact of medical care access and relocation, re-contacted the IHS participants to estimate follow-up rates, and conducted separate studies of cancer cases to evaluate registry coverage (604 cases in Trivandrum) and the accuracy of self- and proxy-reporting (1600 cases in New Delhi and Trivandrum). Results Over 97% of people reported seeing a doctor and 85% had lived in their current residence for over six years. The 2-year follow-up rate was 91% for Trivandrum and 53% for New Delhi. No cancer cases were missed among public institutions participating in the surveillance program in Trivandrum during 2003–04; but there are likely to be unmatched cases (ranging from 5 to13% of total cases) from private hospitals in the Trivandrum registry, as there are no mandatory reporting requirements. Vital status was obtained for 36% of cancer cases in New Delhi as compared to 78% in Trivandrum after a period of 4 years. Conclusions A prospective cohort study of cancer may be feasible in some centers in India with active follow-up to supplement registry data. Inclusion of cancers diagnosed at private institutions, unique identifiers for individuals, and computerized medical information would likely improve cancer registries. PMID:21621499

Most Common Publication Types in Radiology Journals:: What is the Level of Evidence?

PubMed

Rosenkrantz, Andrew B; Pinnamaneni, Niveditha; Babb, James S; Doshi, Ankur M

2016-05-01

This study aimed to assess the most common publication types in radiology journals, as well as temporal trends and association with citation frequency. PubMed was searched to extract all published articles having the following "Publication Type" indices: "validation studies," "meta-analysis," "clinical trial," "comparative study," "evaluation study," "guideline," "multicenter study," "randomized study," "review," "editorial," "case report," and "technical report." The percentage of articles within each category published within clinical radiology journals was computed. Normalized percentages for each category were also computed on an annual basis. Citation counts within a 2-year window following publication were obtained using Web of Science. Overall trends were assessed. Publication types with the highest fraction in radiology journals were technical reports, evaluation studies, and case reports (4.8% to 5.8%). Publication types with the lowest fraction in radiology journals were randomized trials, multicenter studies, and meta-analyses (0.8% to 1.5%). Case reports showed a significant decrease since 1999, with accelerating decline since 2007 (P = 0.002). Publication types with highest citation counts were meta-analyses, guidelines, and multicenter studies (8.1 ± 10.7 to 12.9 ± 5.1). Publication types with lowest citation counts were case reports, editorials, and technical reports (1.4 ± 2.4 to 2.9 ± 4.3). The representation in radiology journals and citation frequency of the publication types showed weak inverse correlation (r = -0.372). Radiology journals have historically had relatively greater representation of less frequently cited publication types. Various strategies, including methodological training, multidisciplinary collaboration, national support networks, as well as encouragement of higher level of evidence by funding agencies and radiology journals themselves, are warranted to improve the impact of radiological research.

This study was aimed to evaluate the possible alert signals of paraesthesia by local anaesthetics, focusing on those used in dentistry. A case/non-case study of spontaneous adverse events recorded in FAERS (FDA Adverse Event Reporting System) between 2004 and 2011 was performed. Cases were represented by the reports of reactions grouped under the term 'Paraesthesias and dysaesthesias' involving local anaesthetics (ATC: N01B*); non-cases were all other reports of the same drugs. Reporting odds ratios (ROR) with the relevant 95% confidence intervals (95CI) were calculated. Alert signal was considered when number of cases >3 and lower limit of ROR 95CI > 1. To estimate the specificity of signals for dentistry, the analysis was restricted to the specific term "Oral Paraesthesia" and to reports concerning dental practice. Overall, 528 reports of 'Paraesthesias and dysaesthesias' were retrieved, corresponding to 573 drug-reaction pairs (247 lidocaine, 99 bupivacaine, 85 articaine, 30 prilocaine, 112 others). The signal was significant only for articaine (ROR=18.38; 95CI = 13.95-24.21) and prilocaine (2.66; 1.82-3.90). The analysis of the specific term "Oral Paraesthesia" retrieved 82 reports corresponding to 90 drug-reaction pairs (37 articaine, 19 lidocaine, 14 prilocaine, 7 bupivacaine, 13 others) and confirmed the signal for articaine (58.77; 37.82-91.31) and prilocaine (8.73; 4.89-15.57). The analysis of reports concerning dental procedures retrieved a signal for articaine, both for any procedures (8.84; 2.79-27.97) and for non-surgical ones (15.79; 1.87-133.46). In conclusion, among local anaesthetics, only articaine and prilocaine generated a signal of paraesthesia, especially when used in dentistry. © 2015 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

Public health significance of zoonotic tapeworms in Korea.

PubMed

Moon, J R

1976-06-01

Through an epidemiological review on the zoonotic tapeworms in Korea, the frequency and severity of the zoonoses have been recognized. Taeniasis and human cysticercosis are of importance to the public health in Korea. The frequency of taeniasis is 0.3% to 12.7% discovered by stool examination and 4.5% to 38.0% discovered by questionaire survey. Taeniasis occurs more frequently in males than in females and, especially, in both sexes in the age-group of 20 to 49. T. saginata is more common that T. solium. No case of human cysticercosis caused by T.saginata has been reported in Korea. To the contrary, human cysticercosis caused by T. solium has been reported frequently during the 1960's. The severity of human cysticercosis is a significant problem of public health in Korea. Old data on bovine cysticercosis in the 1920's and 1930's are not useful for present control measures. Systematic surveys on bovine and swine cysticercosis as well as taeniasis and human cysticercosis are needed in Korea. Cases of sparganosis have been reported frequently during the past 15 years. Most of the 34 cases of sparganosis reported involved the eating of raw snakes and frogs. Most of the cases occurred in older males. Sparganosis in snakes, frogs, chickens, and swine has been reported in Korea. Human infection of Hymenolepis nana ranged from 0.2% to 1.4% discovered by stool examination. A few cases of adult worm collections of Diphyllobothrium latum and Hymenolepis diminuta have been reported in Korea. Two cases of human hydatid disease have been reported in Korea. No study on the disease in domestic animals is available. No case of human infection with dog tapeworm has been reported, even though it is highly prevalent in the indigenous dogs in Korea. I recommend that further study on the zoonotic tapeworms be conducted epidemiologically in Korea to get basic data for the public health programming.

Familial Aggregation of Chiari Malformation: Presentation, Pedigree, and Review of the Literature.

This article reports the largest familial aggregation of Chiari malformation in a single family to date as reported in the literature. This study is a retrospective case series of a family of whom five individuals have a confirmed case of Chiari malformation and three additional individuals have Chiari signs and symptoms. This contribution further supports the implication of genetics in the transmission of Chiari malformation. The family reported in this study also has a significant incidence of Ehlers-Danlos. Three sisters, including a set of twins, presented with confirmed cases of Chiari malformation and four of the five children of the twin sisters presented with confirmed or suspected Chiari malformation. Of note, the non-twin sister has three children who are unaffected. This report provides further evidence for a shared loci between the Chiari malformation and Ehlers-Danlos.

Abstract Child sexual abuse (CSA) is a global problem that affects children of all ages, and the evaluation of these victims by psychologic and gynecologic experts in pediatric emergency departments is an important issue. Few data are available on the characteristics of children admitted to pediatric emergency department with recurrent CSA and delayed reported CSA. The aim of the present study was to describe the clinical features of, and risk factors for, recurrent CSA and delayed reported CSA. The study retrospectively analyzed victims of CSA who were admitted to a pediatric emergency department. Chi-square tests and univariate analyses were performed to assess the risk factors of recurrent or delayed reported CSA. Of the 91 CSA cases, 32 (35.2%) were recurrent assaults. Of the 70 cases recorded the duration of the event, 22 (31.4%) were delayed report cases. Comparisons of the non-recurrent and recurrent CSA assault groups revealed a significant increase in comorbidities (odds ratio [OR]: 4.46, 95% confidence interval [CI]: 1.54–12.93), acute psychiatric problems (OR: 3.18, CI: 1.26–8.06), attempted suicide (OR: 4.23, CI: 1.28–13.99), and the need for treatment with antipsychotic medications (OR: 5.57, CI: 1.37–22.65). Compared with non-delayed reported cases, the delay reported cases of CSA were significantly more likely to have anxiety (P < .05). The CSA victims in the present study exhibited acute medical and/or psychosocial problems, which indicate that pediatric emergency professionals have a responsibility to look for and recognize particular characteristics in these victims.

Between 2006 and 2012 India reported an annual average of 20,474 dengue cases. Although dengue has been notifiable since 1996, regional comparisons suggest that reported numbers substantially underrepresent the full impact of the disease. Adjustment for underreporting from a case study in Madurai district and an expert Delphi panel yielded an annual average of 5,778,406 clinically diagnosed dengue cases between 2006 and 2012, or 282 times the reported number per year. The total direct annual medical cost was US$548 million. Ambulatory settings treated 67% of cases representing 18% of costs, whereas 33% of cases were hospitalized, comprising 82% of costs. Eighty percent of expenditures went to private facilities. Including non-medical and indirect costs based on other dengue-endemic countries raises the economic cost to $1.11 billion, or $0.88 per capita. The economic and disease burden of dengue in India is substantially more than captured by officially reported cases, and increased control measures merit serious consideration. PMID:25294616

High-energy injuries can result in complete or partial loss of the talus. Ipsilateral fractures to the lower limb increase the complexity of surgical management, and treatment is guided by previous case reports of similar injuries. A case of complex lower-extremity trauma with extruded and missing talar body and ipsilateral type IIIB open tibia fracture is presented. Surgical limb reconstruction and salvage was performed successfully with a single orthopaedic implant in a manner not described previously in the literature. The purpose of this case report is to present the novel use of a single orthopaedic implant for treatment of a complex, open traumatic injury. Previous case reports in the literature have described the management of complete or partial talar loss. We describe the novel use of a long hindfoot fusion nail and staged bone grafting to achieve tibiocalcaneal arthrodesis for the treatment of complex lower-extremity trauma.

2011-01-01

Background. The risks of occupational asthma (OA) from antibiotics are uncertain. We report 4 new cases and a systematic review of the literature. Methods. Cases were identified through a specialist clinic, each underwent specific provocation testing (SPT). We subsequently reviewed the published literature. Results. The patients were employed in the manufacture of antibiotics; penicillins were implicated in three cases, in the fourth erythromycin, not previously reported to cause OA. In two, there was evidence of specific IgE sensitisation. At SPT each developed a late asthmatic reaction and increased bronchial hyperresponsiveness. 36 case reports have been previously published, 26 (citing penicillins or cephalosporins). Seven cross-sectional workplace-based surveys found prevalences of 5–8%. Conclusions. OA in antibiotic manufacturers may be more common than is generally recognised. Its pathogenesis remains unclear; immunological tests are of uncertain value and potential cases require confirmation with SPT. Further study of its frequency, mechanisms, and diagnosis is required.

Capsule endoscopy (CE) has an excellent safety profile. Although retention is the most cited complication, capsule aspiration is less frequent and is often reported only as isolated cases. This study represents a systematic effort to compile and scrutinize the available data on capsule aspiration to provide comprehensive and conclusive information on this CE complication. A systematic literature search was performed in PubMed, Embase and Chinese National Knowledge Infrastructure. The search terms used were 'capsule endoscopy' AND 'aspiration' (both terms searched as keyword and MeSH). We included case reports and/or series on capsule aspiration, as well as observational cohort studies that reported capsule aspiration among their complications/outcomes. Thirty-four case reports with 37 cases of capsule aspiration were identified. A further four observational studies reported aspiration as part of a cohort of patients undergoing CE. 94.6% of aspirations occurred in elderly men. 87.1% had significant comorbidities. 59.5% had symptoms on aspiration, with cough reported most frequently. The most common location of aspiration was the right main bronchus. Half of the patients required intervention for capsule retrieval; bronchoscopy was the most common management, with good effect. There was a single fatality following capsule aspiration, not directly related to the procedure, and one case of aspiration pneumonia. Outcomes were good for all other patients. The estimated overall aspiration rate is 0.1%. Although very rare and generally safely managed, capsule aspiration should be anticipated in certain patient groups and capsule administration should be approached with necessary precautions.

To investigate putative associations of reports of memory disorders and suspected drugs. We used the case/noncase method in the French PharmacoVigilance Database (FPVD). Cases were reports of memory loss in the FPVD between January 2000 and December 2009. Noncases were all other reports during the same period. To assess the association between memory impairment and drug intake, we calculated an odds ratio with its 95% confidence interval. Among the 188,284 adverse drug reactions recorded, we identified 519 cases of memory loss. The sex ratio was 0.6 and the median age was 54 years (range 4-93). The maximal number of cases occurred between 40-49 and 50-59 years. Evolution was favourable in 63% of the cases. We found significant odds ratios for benzodiazepines (alprazolam, bromazepam, prazepam, clonazepam etc.), benzodiazepine-like hypnotics (zolpidem and zopiclone), antidepressants (fluoxetine, paroxetine and venlafaxine), analgesics (morphine, nefopam and tramadol), anticonvulsants (topiramate, pregabalin, levetiracetam etc.), antipsychotics (aripiprazole and lithium) and other drugs, such as trihexyphenidyl, ciclosporin and isotretinoin. Our study confirmed an association between memory disorders and some drugs, such as benzodiazepines and anticonvulsants. However, other drugs, such as benzodiazepine-like hypnotics, newer anticonvulsants, serotonin reuptake inhibitor antidepressants, isotretinoin and ciclosporin were significantly associated with memory disorders, although this was not described or poorly described in the literature. Taking account of the limits of this study in the FPVD (under-reporting, notoriety bias etc.), the case/noncase method allows assessment and detection of associations between exposure to drugs and a specific adverse drug reaction, such as memory disorders, and could thus generate signals and orientate us to further prospective studies to confirm such associations. © 2011 The Authors.

2016-01-01

Between December 2010 and July 2011, 252 cases of STEC O157 PT8 stx1 + 2 infection were reported in England, Scotland and Wales. This was the largest outbreak of STEC reported in England and the second largest in the UK to date. Eighty cases were hospitalized, with two cases of haemolytic uraemic syndrome and one death reported. Routine investigative data were used to generate a hypothesis but the subsequent case-control study was inconclusive. A second, more detailed, hypothesis generation exercise identified consumption or handling of vegetables as a potential mode of transmission. A second case-control study demonstrated that cases were more likely than controls to live in households whose members handled or prepared leeks bought unwrapped [odds ratio (OR) 40, 95% confidence interval (CI) 2·08-769·4], and potatoes bought in sacks (OR 13·13, 95% CI 1·19-145·3). This appears to be the first outbreak of STEC O157 infection linked to the handling of leeks.

Gastric adenocarcinoma concurrent with paravertebral plasmacytoma: A case report

2016-01-01

Here, we report the case of a 77-year-old male patient who was revealed to have an unsuspected case of gastric adenocarcinoma with paravertebral plasmacytoma following biopsy. Plasmacytoma may be classified into two main groups: Multiple myeloma and plasmacytoma without marrow involvement. It comprises isolated plasmacytoma of the bone and extramedullary plasmacytoma. Extramedullary plasmacytoma (EMP) accounts for 3% of all plasmacytomas; however, ~80% are located in the upper respiratory tract and upper gastrointestinal tract. It occurs extremely rarely in paravertebral areas. Case reports of EMP and other types of malignant tumor occurring at the same time have not been identified in searches of the literature. In the present study, we describe the diagnosis and treatment process of a case of gastric adenocarcinoma concurrent with paravertebral plasmacytoma. It may be helpful for early clinical diagnosis and treatment of such cases. PMID:27446469

Vocal cord dysfunction (VCD) or paradoxical vocal-fold motion (PVFM) is a functional disorder of the vocal cords that requires multidisciplinary treatment. Besides relaxation techniques, the use of psychological interventions can help treat the underlying psychological co-morbidities. There is currently no literature that examines the effectiveness of psychological interventions for VCD/PVFM. To review the evidence for psychological interventions used for the treatment of patients with VCD/PVFM. We searched electronic databases for English medical literature using Pubmed (Medline), PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Registry of Controlled Trials, and Clinicaltrials.gov. The date range for our search is from June 1964 to June 2014. We included studies that reported the use of psychological interventions in both adults and children diagnosed with VCD/PVFM. We included randomized controlled trials, case-control studies, retrospective chart reviews, prospective case series, and individual case reports. Most reported studies are small case series or individual case reports that have described the use of interventions such as psychotherapy, behavioral therapy, use of anti-anxiety and anti-depressant medications, and hypnotherapy in conjunction with breathing exercises taught by speech therapists for symptomatic relief. Among the various psychological interventions that have been reported, there is no data regarding effectiveness and/or superiority of one approach over another in either adult or pediatric patients. Psychological interventions have a role to play in the management of adult and pediatric patients with VCD/PVFM. Future prospective studies using uniform approaches for treatment of associated psychopathology may help address this question.

Low-Pressure Hydrocephalus: A Case Report and Review of the Literature.

Strand, Adam; Balise, Stephen; Leung, Lawrence Jun; Durham, Susan

2018-01-01

The entity of low-pressure hydrocephalus remains poorly understood and thoroughly debated. Symptomatic improvement accompanied by decrease in ventricular size after prolonged subatmospheric drainage has been well documented, and this method has been considered the criterion standard of management. Few studies have examined alternative treatment options, either to avoid the risks associated with prolonged external ventricular drainage or because of the failure of traditional methods. This study compiled and examined reported cases of low-pressure hydrocephalus in an attempt to provide an up-to-date summary of the condition. A literature search was conducted by use of Ovid Medline and PubMed filtered for the past 25 years with specific key terms, inclusion criteria, and exclusion criteria. Selected case studies and case series were then compared, and statistical analysis was performed where appropriate. Over 25 years, 17 articles met our criteria. In addition to our case, 90 cases of LPH were reported. Magnetic resonance elastography (MRE) has proved to be an effective means of studying the viscoelastic properties of the brain. Endoscopic third ventriculostomy (ETV) appears to be a strong alternative, or additional, treatment. MRE may prove to be effective in studying LPH because of its ability to quantify viscoelastic properties in response to therapy. Additionally, ETV should be considered in cases of LPH, although there is little evidence in the current literature to support its use. There are suggestions that it may lead to fewer shunt-dependent patients. Future studies are needed because there are few documented examples. Copyright © 2017 Elsevier Inc. All rights reserved.

Dedifferentiated liposarcoma (DDLS) has a relatively poor prognosis, however this neoplasm rarely occurs in the head and neck. To date, no definite protocol has been established for the diagnosis and treatment of head and neck DDLS. The present study reports the case of a 69-year-old male patient with DDLS of the oral floor. To the best of our knowledge, this is the first documented case of oral floor DDLS. In addition, this is the first reported case with the development of a second primary malignancy following the treatment of head and neck DDLS. A literature review of 50 cases of head and neck DDLS revealed that preoperative biopsy is not reliable for the diagnosis of these tumors and an accurate pathological diagnosis with total resection is preferred.

The categorization of disorders of gender differentiation is based on chromosome analysis, physical examination, gonadal histology, and endocrine evaluation. In most cases of hermaphroditism, radiologic studies have been limited to assessment of associated urinary tract anomalies before surgical revconstruction. Noninvasive evaluation with computed tomography (CT) or sonography is potentially useful for investigation of internal pelvic anatomy in these cases. A case report of a 65-year-old man is reported.

Wittayanukorn, Saranrat; Qian, Jingjing; Johnson, Brandon S; Hansen, Richard A

2017-03-01

Purpose Cancer chemotherapy-induced cardiotoxicity is concerning. Certain anthracyclines and targeted therapies are known to have potential for cardiotoxicity, but existing trial evidence is inadequate to understand real-world patterns of cardiotoxicity with newer targeted therapies and their common combinations with older agents. This study evaluated chemotherapy-related cardiotoxicity reports for targeted therapies and their combinations in breast cancer patients. Methods The US Food and Drug Administration Adverse Event Reporting System (FAERS) database from January 2004 through September 2012 was used to summarize characteristics of reported cardiotoxicity events and their health outcomes. Disproportionality analyses with reporting odds ratios (ROR) and 95% confidence intervals (95% CI) were conducted to detect event signals using a case/non-case method for each targeted therapy and combination. Results A total of 59,739 cases of cardiotoxicity reports were identified; 937 cases identified targeted therapy as the suspect drug. Trastuzumab had the highest number of reports followed by bevacizumab and lapatinib. Proportions of reports of death and disability outcomes for each targeted therapy were approximately 20-25% of the total reports of serious events. Trastuzumab had the highest ROR as a single agent (ROR = 5.74; 95% CI = 5.29-6.23) or combination use of cyclophosphamide (ROR = 16.83; 95% CI = 13.32-21.26) or doxorubicin (ROR = 17.84; 95% CI = 13.77-23.11). Relatively low cardiotoxicity reporting rates were found with lapatinib, regardless of use with combination therapy. Conclusions Analysis of FAERS data identified signals for adverse cardiotoxicity events with targeted therapies and their combinations. Practitioners should consider factors that may increase the likelihood of cardiotoxicity when assessing treatment. Findings support continued surveillance, risk factor identification, and comparative studies.

Parasystole due to re-entry as the possible mechanism of ventricular parasystole with second-degree entrance block.

PubMed

Kinoshita, Shinji; Katoh, Takakazu; Yoshida, Hiroshi

2010-05-01

In 1974, Kinoshita reported a case of 'irregular parasystole' due to type I second-degree entrance block. Since then, many cases of such 'irregular' parasystole have been reported by us. To explain the mechanism of 'irregular' parasystole, two theories have been suggested, namely, 'electrotonic modulation' by Jalife and Moe, and 'type I second-degree entrance block' by us. On the contrary, in 1960, Kinoshita et al. reported a case of concealed bigeminy for the first time. The electrocardiographic findings in concealed bigeminy have suggested that there are dual re-entrant pathways with markedly long effective refractory periods in the re-entrant pathway. We have suggested that parasystole may be caused by re-entry in such re-entrant pathways. In this article, attempts are made to explain the mechanism of all the electrocardiographic findings in our cases of parasystole by 'parasystole due to re-entry'. Using 24 studies on parasystole and 21 studies on concealed extrasystoles that we have reported over 50 years, as well as three exemplary cases in this article, attempts are made to explain all electrocardiographic findings in parasystole by 'parasystole due to re-entry'. The electrocardiographic findings in our previous clinical cases of parasystole and concealed extrasystoles, as well as exemplary cases and diagrams in the present article, strongly suggest 'parasystole due to re-entry' as the mechanism of ventricular parasystole with second-degree entrance block.

This analysis estimates the economic impacts of a wide variety of ecosystem restoration projects associated with U.S. Department of the Interior (DOI) lands and programs. Specifically, the report provides estimated economic impacts for 21 DOI restoration projects associated with Natural Resource Damage Assessment and Restoration cases and Bureau of Land Management lands. The study indicates that ecosystem restoration projects provide meaningful economic contributions to local economies and to broader regional and national economies, and, based on the case studies, we estimate that between 13 and 32 job-years4 and between $2.2 and $3.4 million in total economic output5 are contributed to the U.S. economy for every $1 million invested in ecosystem restoration. These results highlight the magnitude and variability in the economic impacts associated with ecosystem restoration projects and demonstrate how investments in ecosystem restoration support jobs and livelihoods, small businesses, and rural economies. In addition to providing improved information on the economic impacts of restoration, the case studies included with this report highlight DOI restoration efforts and tell personalized stories about each project and the communities that are positively affected by restoration activities. Individual case studies are provided in appendix 1 of this report and are available from an online database at https://www.fort.usgs.gov/economic-impacts-restoration.

Comparing habitual nutrient intakes in persons with a history of acute myocardial infarction (AMI), and age-matched controls. Design. Cross-sectional study. Subjects. Men and women (525 cases and 1890 matched controls), aged 47-73 years, of the population-based Malmö Diet and Cancer cohort. Nutrient intakes were assessed by a validated modified diet history method. Body fatness was assessed by bioimpedance analysis. Case ascertainment was provided by national and regional registries. Men and women were analysed separately. Median time since AMI was 5.5 years in men and 3.8 years in women. Cases reported lower energy intakes (EIs) than controls, despite having similar basal metabolic rates. After adjustment for total EI, both male and female cases had lower fat intake and higher intake of several micronutrients, such as ascorbic acid, folate, and vitamin E, than controls, the difference being largest in men. Most of the cases reporting dietary change quoted 'disease' as their main reason for change. They had lower EI and lower energy-adjusted intake of fat than other cases. Survivors of AMI reported dietary habits more in line with current recommendations, particularly those who afterwards reported having changed their dietary habits. The possible bias introduced by social desirability is discussed.

Antiphospholipid syndrome is revealed by Budd Chiari syndrome in 5% of the cases. Antiphospholipid syndrome is characterized by venous or arterial thrombosis, foetal loss and positivity of antiphospholipid antibodies, namely lupus anticoagulant, anticardiolipin antibodies and anti-beta2-glycoprotein I. Anticardiolipin antibodies was reported in auto-immune thyroid disorders, particularly in Grave's disease. Antiphospholipid syndrome associated to Grave's disease was reported in only three cases. To describe a case report of association of Grave's disease and antiphospholipid syndrome. We report the first case of Grave's disease associated with antiphospholipid syndrome, revealed by Budd Chiari syndrome. Our observation is particular by the fact that it is about a patient presenting a Grave's disease associated with antiphospholipid syndrome revealed by Budd Chiari syndrome. This triple association has never been reported in literature. Although association between antiphospholipid syndrome and Grave's disease was previously described, further studies evaluating the coexistence of these two affections in the same patient would be useful.

To report four additional cases of secondary amyloidosis of the bladder, an extremely rare condition, as shown by the cases reported in the literature. Four clinical cases are reported, all of them occurring as hematuria, which was massive and fulminant and resulted in death in three patients. Secondary amyloidosis of the bladder is of the AA type, which is more common in females and mainly secondary to rheumatoid arthritis, but also to ankylosing spondylitis and long-standing chronic inflammatory conditions. Hematuria is the main and virtually only symptom. A pathological and immunohistochemical study confirmed diagnosis. All three patients who experienced massive, fatal hematuria had an intercurrent condition requiring urethral catheterization, which was the triggering factor. Despite its rarity, as shown by the few cases reported, secondary amyloidosis of the bladder should be considered in patients already diagnosed with systemic amyloidosis and/or the conditions reported who require simple urethral catheterization.

Report writing is an important employability skill for Engineers and Technologists, and this case study describes how a Technology degree module took a novel approach to developing students' report writing skills. Students learned how to use a criterion-referenced critical evaluation framework for reports and other technological documents. They were given opportunities to practise using the framework both through exemplars and through evaluating the work of their peers. They also carried out self-assessment. The authors' analysis of this novel approach shows that most students responded well to it and benefited from it. Lessons are drawn from this work for others who wish to improve their students' report writing skills.

Case investigation and reactive case detection (RACD) activities are widely-used in low transmission settings to determine the suspected origin of infection and identify and treat malaria infections nearby to the index patient household. Case investigation and RACD activities are time and resource intensive, include methodologies that vary across eliminating settings, and have no standardized metrics or tools available to monitor and evaluate them. In response to this gap, a simple programme tool was developed for monitoring and evaluating (M&E) RACD activities and piloted by national malaria programmes. During the development phase, four modules of the RACD M&E tool were created to assess and evaluate key case investigation and RACD activities and costs. A pilot phase was then carried out by programme implementers between 2013 and 2015, during which malaria surveillance teams in three different settings (China, Indonesia, Thailand) piloted the tool over a period of 3 months each. This study describes summary results of the pilots and feasibility and impact of the tool on programmes. All three study areas implemented the RACD M&E tool modules, and pilot users reported the tool and evaluation process were helpful to identify gaps in RACD programme activities. In the 45 health facilities evaluated, 71.8% (97/135; min 35.3-max 100.0%) of the proper notification and reporting forms and 20.0% (27/135; min 0.0-max 100.0%) of standard operating procedures (SOPs) were available to support malaria elimination activities. The tool highlighted gaps in reporting key data indicators on the completeness for malaria case reporting (98.8%; min 93.3-max 100.0%), case investigations (65.6%; min 61.8-max 78.4%) and RACD activities (70.0%; min 64.7-max 100.0%). Evaluation of the SOPs showed that knowledge and practices of malaria personnel varied within and between study areas. Average monthly costs for conducting case investigation and RACD activities showed variation between study areas (min USD $844.80-max USD $2038.00) for the malaria personnel, commodities, services and other costs required to carry out the activities. The RACD M&E tool was implemented in the three pilot areas, identifying key gaps that led to impacts on programme decision making. Study findings support the need for routine M&E of malaria case reporting, case investigation and RACD activities. Scale-up of the RACD M&E tool in malaria-eliminating settings will contribute to improved programme performance to the high level that is required to reach elimination.

We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study, an alternative account in the framework of (non abstractive) episodic models of memory.

The efficiency in the utilization of potential donors for organ transplantation in Riyadh, Saudi Arabia.

Organ transplantation programs have been successful in the Kingdom of Saudi Arabia. This success is limited by organ shortage. The aim of this study is to find out the percentage of actual donors out of all potential donors in intensive care units (ICU), and to look at problems related to the donation process, particularly from the logistical point of view. The study was conducted prospectively for a one year period, June 2001 through to May 2002, in 4 main Riyadh hospitals. Mortality data was collected by a medical professional in each ICU and analyzed on a weekly basis. Final analysis was made at the end of the year. Five hundred and forty-two deaths occurred in these ICUs. Fifty-four percent occurred in one hospital. The number of brain death cases in all hospitals was 114 cases. Thirty-eight cases were reported to the Saudi Center for Organ Transplantation (33%). Documentation was completed in only 23 cases (60%). In these, there was a significant delay in documentation (second test was carried out in 6-12 hours in 4 cases only). We have found that the reporting of brain death cases was low (33%). Dealing with the reported cases is inefficient since only 4 cases were able to become the actual donor out of 38 cases. We found also that there is a gross difference in the number of brain death cases among different hospitals. To improve the efficiency of ICUs in dealing with brain death cases (reporting, documentation, maintenance and consent) will require solving several problems at the medical, administrative, and religious and mass media levels.

Gastrointestinal illnesses (GI) continue to pose a substantial burden in terms of morbidity and economic impact in Canada. We describe the epidemiology of reportable GI in Ontario by characterizing the incidence of each reportable GI, as well as associated demographics, clinical outcomes, seasonality, risk settings, and likely sources of infection. Reports on laboratory confirmed cases of amebiasis, botulism, campylobacteriosis, cryptosporidiosis, cyclosporiasis, giardiasis, hepatitis A, listeriosis, paratyphoid fever, salmonellosis, shigellosis, typhoid fever, illness due to verotoxin-producing Escherichia coli (VTEC-illness), and yersiniosis, from January 1, 2007 to December 31, 2009 were obtained from Ontario's passive reportable disease surveillance system. Cases were classified by history of relevant travel, association with outbreaks, and likely source of infection, obtained through follow-up of reported cases by local health authorities. There were 29,897 GI reported by health authorities in Ontario from 2007 to 2009. The most frequently reported diseases were campylobacteriosis (10,916 cases or 36.5% of all GI illnesses) and salmonellosis (7,514 cases, 25.1%). Overall, 26.9% of GI cases reported travel outside of Ontario during the relevant incubation period. Children four years of age and younger had the highest incidence rate for most GI, and significantly more (54.8%, p<0.001) cases occurred among males than females. The most commonly reported sources of infections were food (54.2%), animals (19.8%), and contact with ill persons (16.9%). Private homes (45.5%) and food premises (29.7%) were the most commonly reported exposure settings. Domestic cases of campylobacteriosis, cryptosporidiosis, giardiasis, salmonellosis, and VTEC-illness showed seasonal patterns with incidence peaking in the summer months. Reportable GI continues to be a burden in Ontario. Since more than one in four GI cases experienced in Ontario were acquired outside of the province, international travel is an important risk factor for most GI. Because private homes are the most commonly reported risk settings and the main suspect sources of infection are food, animal contact and ill persons, these findings support the continued need for public health food safety programs, public education on safe handling of food and animals, and proper hand hygiene practices.

2018-01-01

ABSTRACT Angioedema has recently been reported as a side effect associated with the antipsychotic risperidone. We report a case of dystonia with concurrent angioedema due to risperidone. A 40-year-old male with a history of schizophrenia was started on 3 mg of risperidone BID and developed perioral and periorbital edema along with increased muscle rigidity and hand tremor within 24 h of initial administration. His symptoms abated after cessation of risperidone and intravenous administration of corticosteroids and antihistamine. This case study adds to the current literature, which has already established angioedema as a dose-dependent side effect of risperidone. Moreover, this case study aims to increase awareness about the potential for the simultaneous occurrence of angioedema and extrapyramidal symptoms, and promotes vigilance among prescribers so that the life-threatening consequences of such effects can be avoided.

Childhood tuberculosis (TB) has been neglected in the fight against TB. Despite implementation of Directly Observed Treatment Shortcourse (DOTS) program in public and private hospitals in Indonesia since 2000, the burden of childhood TB in hospitals was largely unknown. The goals of this study were to document the caseload and types of childhood TB in the 0-4 and 5-14 year age groups diagnosed in DOTS hospitals on Java Island, Indonesia. Cross-sectional study of TB cases recorded in inpatient and outpatient registers of 32 hospitals. Cases were analyzed by hospital characteristics, age groups, and types of TB. The number of cases reported in the outpatient unit was compared with that recorded in the TB register. Of 5,877 TB cases in the inpatient unit and 15,694 in the outpatient unit, 11% (648) and 27% (4,173) respectively were children. Most of the childhood TB cases were under five years old (56% and 53% in the inpatient and outpatient clinics respectively). The proportion of smear positive TB was twice as high in the inpatient compared to the outpatient units (15.6% vs 8.1%). Extra-pulmonary TB accounted for 15% and 6% of TB cases in inpatient and outpatient clinics respectively. Among children recorded in hospitals only 1.6% were reported to the National TB Program. In response to the high caseload and gross under-reporting of childhood TB cases, the National TB Program should give higher priority for childhood TB case management in designated DOTS hospitals. In addition, an international guidance on childhood TB recording and reporting and improved diagnostics and standardized classification is required.

The purpose of this institutional review board-approved, cross-sectional study was to identify residual symptoms and signs of envenomation reported by snakebite survivors via a telephone survey. Victims of rattlesnake bite who were treated at a single hospital center during a 10-year period were contacted through a telephone survey. Study subjects were included through a diagnosis-based retrospective chart review of snakebite victims, and excluded if they did not receive rattlesnake antivenom. Data collection was done using a standardized form that included sections about residual, recurrent, or new pain, weakness, paresthesias, or other limitations of the bitten limb. We identified 46 snakebite cases including 5 of 46 "dry" bites. The remaining cases (41 of 46) all received Crofab. Interviews were completed for 31% of these patients (13 of 41), and the remainder were lost to follow-up. Most bites occurred in men (12 cases, 92% males) and on the arms (9 cases, 69%). Six of the 13 respondents (46%) reported residual symptoms from the bite. Persistent symptoms described included localized pain at the bite site (3 cases), numbness or paresthesias (2 cases), abnormal skin peeling and discoloration at the bite site (2 cases), and persistent weakness of the bitten extremity (1 case). Among patients reporting persistent symptoms, the bite-to-survey interval ranged from 7 months to 12 years, with a median interval of 4 years. Our study population demonstrated a notable incidence (43%) of self-reported persistent symptoms related to their rattlesnake bites, although the overall level of disability from these injuries seems low.

Dermatoglyphics in kidney diseases: a review.

2016-01-01

Kidney diseases are becoming a major cause of global burden with high mortality and morbidity. The origins of most kidney diseases are known, but for some the exact aetiology is not yet understood. Dermatoglyphics is the scientific study of epidermal ridge patterns and it has been used as a non-invasive diagnostic tool to detect or predict different medical conditions that have foetal origin. However, there have been a limited number of studies that have evaluated a dermatoglyphic relationship in different kidney diseases. The aim of this review was to systematically identify, review and appraise available literature that evaluated an association of different dermatoglyphic variables with kidney diseases. This review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. The PubMed(®) (Medline), POPLINE, Cochrane Library and Trip Database and grey literature sources such as OpenGrey, Google Scholar, and Google were searched to earliest date to 17 April 2014. Of the 36 relevant publications, 15 were included in the review. Of these studies, there are five case reports, seven case series and three comparative studies. Possible association of dermatoglyphics with Wilms tumor (WT) had been evaluated in two comparative studies and one case series that found fewer whorls and a lower mean total ridge count (TRC). Another study evaluated adult polycystic kidney disease (APCD) type III that revealed lower TRC means in all cases. All other case series and case reports describe dermatoglyphics in various kidney disease such as acro-renal-ocular syndrome, potter syndrome, kabuki makeup syndrome, neurofaciodigitorenal syndrome, syndactyly type V, ring chromosome 13 syndrome, trisomy 13 syndrome and sirenomelia. It is evident that whorl pattern frequency and TRC have been used widely to investigate the uncertainty related to the origin of several kidney diseases such as WT and APCD type III. However, small sample sizes, possibly methodological issues, and discrepancy in the make up between cases and control groups limits interpretation of any significant findings. Future studies with proper protocol, adequate cases, and control groups may provide stronger evidence to resolve uncertainty related to the aetiology of kidney diseases.

Epidemiological Profile of Wild Rabies in Brazil (2002-2012).

PubMed

Rocha, S M; de Oliveira, S V; Heinemann, M B; Gonçalves, V S P

2017-04-01

Rabies is one of the most important zoonosis in the world with high impact on public health. Studies report the presence of Lyssavirus in reservoirs of the wild cycle, highlighting the role of wild canines, marmosets, and vampire and non-vampire bats as potential vectors of the disease to domestic animals and human beings. Therefore, the reintroduction of rabies in urban environments from reservoirs of the wild cycle is a matter of concern. This study describes the profile of rabies cases documented in Brazil from 2002 to 2012, with emphasis on the wild transmission cycle of the disease. We carried out a descriptive study using records with information on the time of infection, persons with infection and location of confirmed cases of rabies in humans and animals, as well as data on anti-rabies treatments obtained from the Information System of Notifiable Diseases (Sinan) database. Within the study period, 82 cases of rabies transmitted by wild animals to humans were reported, predominantly in rural areas of the northern and north-eastern regions. Of the cases in humans, 72% did not receive post-exposure prophylaxis. Among wild mammals, vampire bats were the most frequent vectors of the disease. In the north-east region, 460 terrestrial wild mammals were reported with confirmed rabies. Over the study period, 1703 bats were reported to carry the rabies virus. In the south-east region, the most frequently reported carriers of the virus were non-vampire bats. The midwest and northern regions presented a lower number of records of rabies cases among terrestrial wild mammals. However, the high number of rabies cases among bovines reflects the role of the vampire bat as a maintainer of the rabies virus in the rural cycle. The present results are key to adjust the planning of rabies control in Brazil to the current epidemiological trends. © 2015 Blackwell Verlag GmbH.

Euthanasia in patients dying at home in Belgium: interview study on adherence to legal safeguards

2010-01-01

Background Euthanasia became legal in Belgium in 2002. Physicians must adhere to legal due care requirements when performing euthanasia; for example, consulting a second physician and reporting each euthanasia case to the Federal Review Committee. Aim To study the adherence and non-adherence of GPs to legal due care requirements for euthanasia among patients dying at home in Belgium and to explore possible reasons for non-adherence. Design of study Large scale, retrospective study. Setting General practice in Belgium. Method A retrospective mortality study was performed in 2005–2006 using the nationwide Belgian Sentinel Network of General Practitioners. Each week GPs reported medical end-of-life decisions taken in all non-sudden deaths of patients in their practice. GP interviews were conducted for each euthanasia case occurring at home. Results Interviews were conducted for nine of the 11 identified euthanasia cases. Requirements concerning the patient's medical condition were met in all cases. Procedural requirements such as consultation of a second physician were sometimes ignored. Euthanasia cases were least often reported (n = 4) when the physician did not regard the decision as euthanasia, when only opioids were used to perform euthanasia, or when no second physician was consulted. Factors that may contribute to explaining non-adherence to the euthanasia law included: being unaware of which practices are considered to be euthanasia; insufficient knowledge of the euthanasia law; and the fact that certain procedures are deemed burdensome. Conclusion Substantive legal due care requirements for euthanasia concerning the patient's request for euthanasia and medical situation were almost always met by GPs in euthanasia cases. Procedural consultation and reporting requirements were not always met. PMID:20353662

News media reports of patient deaths following 'medical tourism' for cosmetic surgery and bariatric surgery.

PubMed

Turner, Leigh

2012-04-01

Contemporary scholarship examining clinical outcomes in medical travel for cosmetic surgery identifies cases in which patients traveled abroad for medical procedures and subsequently returned home with infections and other surgical complications. Though there are peer-reviewed articles identifying patient deaths in cases where patients traveled abroad for commercial kidney transplantation or stem cell injections, no scholarly publications document deaths of patients who traveled abroad for cosmetic surgery or bariatric surgery. Drawing upon news media reports extending from 1993 to 2011, this article identifies and describes twenty-six reported cases of deaths of individuals who traveled abroad for cosmetic surgery or bariatric surgery. Over half of the reported deaths occurred in two countries. Analysis of these news reports cannot be used to make causal claims about why the patients died. In addition, cases identified in news media accounts do not provide a basis for establishing the relative risk of traveling abroad for care instead of seeking elective cosmetic surgery at domestic health care facilities. Acknowledging these limitations, the case reports suggest the possibility that contemporary peer-reviewed scholarship is underreporting patient mortality in medical travel. The paper makes a strong case for promoting normative analyses and empirical studies of medical travel. In particular, the paper argues that empirically informed ethical analysis of 'medical tourism' will benefit from rigorous studies tracking global flows of medical travelers and the clinical outcomes they experience. The paper contains practical recommendations intended to promote debate concerning how to promote patient safety and quality of care in medical travel. © 2012 Blackwell Publishing Ltd.

Waardenburg syndrome (WS) is a genetic disorder characterized primarily by depigmentation of the skin and hair, heterochromia of the irides, sensorineural deafness, and sometimes by dystopia canthorum, and Hirschsprung disease. WS presents a large clinical and genetic heterogeneity. Four different types have been individualized and linked to 5 different genes. We report 2 cases of WS type II and 1 case of WS type IV from Lebanon and Syria. The genetic studies revealed 2 novel mutations in the MITF gene of the WS type II cases and 1 novel homozygous mutation in the EDNRB gene of the WS type IV case. This is the first molecular study of patients from the Arab world. Additional cases will enable a more detailed description of the clinical spectrum of Waardenburg syndrome in this region.

Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

In nocturnal frontal lobe epilepsy (NFLE), seizures occur almost exclusively during NREM sleep. Why precisely these seizures are sleep-bound remains unknown. Studies of patients with nonlesional familial forms of NFLE have suggested the arousal system may play a major role in their pathogenesis. We report the case of a patient with pharmaco-resistant, probably cryptogenic form of non-familial NFLE and strictly sleep-bound seizures that could be elicited by alerting stimuli and were associated with ictal bilateral thalamic and right orbital-insular hyperperfusion on SPECT imaging. Case report. University Hospital Zurich. One patient with pharmaco-resistant epilepsy. This case shows that the arousal system plays a fundamental role also in cryptogenic non-familial forms of NFLE.

Little is known about the characteristics of acute viral hepatitis cases in the United States (US)-Mexico border region. We analyzed characteristics of acute viral hepatitis cases collected from the Border Infectious Disease Surveillance Project from January 2000-December 2009. Over the study period, 1,437 acute hepatitis A, 311 acute hepatitis B, and 362 acute hepatitis C cases were reported from 5 Mexico and 2 US sites. Mexican hepatitis A cases most frequently reported close personal contact with a known case, whereas, US cases most often reported cross-border travel. Injection drug use was common among Mexican and US acute hepatitis B and C cases. Cross-border travel during the incubation period was common among acute viral hepatitis cases in both countries. Assiduous adherence to vaccination and prevention guidelines in the US is needed and strategic implementation of hepatitis vaccination and prevention programs south of the border should be considered.

Pelvic Actinomycosis

2017-01-01

Introduction Actinomycosis is a chronic bacterial infection caused by Actinomyces, Gram-positive anaerobic bacteria. Its symptomatology imitates some malignant pelvic tumours, tuberculosis, or nocardiosis, causing abscesses and fistulas. Actinomycoses are opportunistic infections and require normal mucous barriers to be altered. No epidemiological studies have been conducted to determine prevalence or incidence of such infections. Objective To analyse the clinical cases of pelvic actinomycosis reported worldwide, to update the information about the disease. Methods A systematic review of worldwide pelvic actinomycosis cases between 1980 and 2014 was performed, utilising the PubMed, Scopus, and Google Scholar databases. The following information was analysed: year, country, type of study, number of cases, use of intrauterine device (IUD), final and initial diagnosis, and method of diagnosis. Results 63 articles met the search criteria, of which 55 reported clinical cases and 8 reported cross-sectional studies. Conclusions Pelvic actinomycosis is confusing to diagnose and should be considered in the differential diagnosis of pelvic chronic inflammatory lesions. It is commonly diagnosed through a histological report, obtained after a surgery subsequent to an erroneous initial diagnosis. A bacterial culture in anaerobic medium could be useful for the diagnosis but requires a controlled technique and should be performed using specialised equipment. PMID:28684963

Summary The Middle East respiratory syndrome coronavirus (MERS-CoV) was first described in September 2012 and to date 86 deaths from a total of 206 cases of MERS-CoV infection have been reported to the WHO. Camels have been implicated as the reservoir of MERS-CoV, but the exact source and mode of transmission for most patients remain unknown. During a 3 month period, June to August 2013, there were 12 positive MERS-CoV cases reported from the Hafr Al-Batin region district in the north east region of the Kingdom of Saudi Arabia. In addition to the different regional camel festivals in neighboring countries, Hafr Al-Batin has the biggest camel market in the entire Kingdom and hosts an annual camel festival. Thus, we conducted a detailed epidemiological, clinical and genomic study to ascertain common exposure and transmission patterns of all cases of MERS-CoV reported from Hafr Al-Batin. Analysis of previously reported genetic data indicated that at least two of the infected contacts could not have been directly infected from the index patient and alternate source should be considered. While camels appear as the likely source, other sources have not been ruled out. More detailed case control studies with detailed case histories, epidemiological information and genomic analysis are being conducted to delineate the missing pieces in the transmission dynamics of MERS-CoV outbreak.

Previous studies on breast cancer (BC), underarm cosmetic products (UCP) and aluminum salts have shown conflicting results. We conducted a 1:1 age-matched case-control study to investigate the risk for BC in relation to self-reported UCP application. Self-reported history of UCP use was compared between 209 female BC patients (cases) and 209 healthy controls. Aluminum concentration in breast tissue was measured in 100 cases and 52 controls. Multivariable conditional logistic regression analysis was performed to estimate odds ratios (ORs) with 95% confidence intervals (CIs), adjusting for established BC risk factors. Use of UCP was significantly associated with risk of BC (p=0.036). The risk for BC increased by an OR of 3.88 (95% CI 1.03-14.66) in women who reported using UCP's several times daily starting at an age earlier than 30years. Aluminum in breast tissue was found in both cases and controls and was significantly associated to self-reported UCP use (p=0.009). Median (interquartile) aluminum concentrations were significantly higher (p=0.001) in cases than in controls (5.8, 2.3-12.9 versus 3.8, 2.5-5.8nmol/g). Frequent use of UCPs may lead to an accumulation of aluminum in breast tissue. More than daily use of UCPs at younger ages may increase the risk of BC. Copyright © 2017 The Authors.

Escitalopram (ESC) is considered one of the most effective selective serotonin reuptake inhibitors (SSRI) for the treatment of major depression disorder. However, little is known on its potential risk of inducing major malformations (MM) and/or perinatal complications (PC). Aim of the present study is to provide a review of the available literature on the safety profile of ESC during pregnancy and breastfeeding and to compare data with the maternal and neonatal outcomes of 8 cases of the DEGRA Center. MEDLINE and PubMed databases were searched for English language articles by using the following keywords: "escitalopram", "selective serotonin reuptake inhibitors", "major malformations", "perinatal complications", "pregnancy", "breastfeeding". We also reported 8 cases of women treated with ESC during their pregnancy and breastfeeding at the Clinic of Affective Disorders in Pregnancy and Postpartum of the United Hospital of Ancona (DEGRA Center). Although some cases of MM have been reported in the literature after maternal exposure to ESC during early pregnancy, the rate of MM is substantially in the range of those reported in unexposed women. ESC exposure seems to be significantly associated with some PC such as lower rates of live births and higher rates of newborns with low birth weight. On the contrary, no short-term adverse effects in newborns were reported in the 5 studies evaluating the safety of ESC during breastfeeding. Data coming from DEGRA Center are consistent with the literature: all pregnancy were full term, all newborns were healthy and obtained normal APGAR score; no MM or miscarriage were reported. Only one case of mild withdrawal syndrome was reported in a newborn who was also exposed to benzodiazepines and paroxetine late in pregnancy. Two infants exposed to ESC also during the lactation did not reported any adverse effects at short-term. Data coming from published studies and from our cases seem to support the notion that ESC might be considered safe during pregnancy and breastfeeding, particularly as far as MM is concerned. As well as other SSRI it could be associated with an increased risk of PC. Nevertheless, given the few cases here analysed and the paucity of the studies so far published, no definitive conclusions should be drawn.

Finger drop sign-Characteristic pattern of distal weakness in Guillain-Barré Syndrome: A case report and review of the literature.

PubMed

Chee, Yong Chuan; Ong, Beng Hooi

2018-01-01

Guillain-Barré Syndrome is an acquired acute autoimmune polyradiculoneuropathy that commonly presents with limb weakness and occasional cranial nerve, respiratory and autonomic involvement. Although the classic description of Guillain-Barré Syndrome is that of a demyelinating neuropathy with ascending weakness, predominant bilateral finger drop as presenting feature has rarely been reported. A characteristic pattern of weakness involving the extensor components of the fingers known as "finger drop sign" has been first described to be specific in acute motor axonal neuropathy form of Guillain-Barré Syndrome in the literature. We report a case of acute motor-sensory axonal neuropathy, which showed characteristic pattern of predominant finger extensor weakness, and provide a summary of all reported cases to date. While previous reports suggested that this is a sign that carries good prognosis, our case report suggested otherwise as the patient succumbed to respiratory and autonomic complications. Further studies are needed to evaluate the clinical significance of this peculiar sign.

Radionuclide demonstration of urinary extravasation with ureteral obstruction

DOE Office of Scientific and Technical Information (OSTI.GOV)

Yeh, V.A.; Chiang, L.C.; Meade, R.C.

Two cases of urinary extravasation with ureteral obstruction demonstrated by the radionuclide studies are reported. The value of radionuclide studies in patients with renal transplantation has been reported previously, but studies in patients without transplantation have rarely been described in the literature. Ureteral obstruction may cause urinary extravasation, which may be demonstrated by radionuclide studies even when radiologic studies are inconclusive. In one case, urinary extravasation was detected in the sitting position but not in the supine position. Renal imaging should probably be performed not only with multiple projections but also in different positions.

This study reports the epidemiological characteristics of hospitalized cases of influenza A(H1N1)pdm09 infection analyzed on the basis of surveillance data collected from July 24, 2009, the date on which the hospital-based surveillance of influenza cases was implemented in Japan, to September 5, 2010. During the study period, 13,581 confirmed cases were reported. Among those cases with information regarding the reason for hospitalization, 39% were admitted to hospitals for non-therapeutic purposes such as medical observation and laboratory testing. The overall hospitalization rate was 5.8 cases per 100,000 population when cases hospitalized for non-therapeutic purposes were excluded. While those aged under 20 years accounted for over 85% of hospitalized cases, the largest proportion of fatal cases was observed in those aged over 65 years. The overall case fatality rate for all hospitalized cases was 1.5%. The year-round surveillance for hospitalized influenza-like illness cases was launched in 2011, and it was expected that this surveillance system could add value by monitoring changes in the epidemiological characteristics of hospitalized cases of seasonal influenza.

An interpretation report, generated with an electronic viewbox, is affected by two factors: image quality, which encompasses what can be seen on the display, and computer human interaction (CHI), which accounts for the cognitive load effect of locating, moving, and manipulating images with the workstation controls. While a number of subject experiments have considered image quality, only recently has the affect of CHI on total interpretation quality been measured. This paper presents the results of a pilot study conducted to evaluate the total interpretation quality of the FilmPlane2.2 radiology workstation for patient folders containing single forty-slice CT studies. First, radiologists interpreted cases and dictated reports using FilmPlane2.2. Requisition forms were provided. Film interpretation was provided by the original clinical report and interpretation forms generated from a previous experiment. Second, an evaluator developed a list of findings for each case based on those listed in all the reports for each case and then evaluated each report for its response on each finding. Third, the reports were compared to determine how well they agreed with one another. Interpretation speed and observation data was also gathered.

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.

Syphilis cases have risen in many parts of China, with developed regions reporting the greatest share of cases. Since syphilis increases in these areas are likely driven by both increased screening and changes in sexual behaviours, distinguishing between these two factors is important. Examining municipal-level primary syphilis cases with spatial analysis allows a more direct understanding of changing sexual behaviours at a more policy-relevant level. In this study we examined all reported primary syphilis cases from Guangdong Province, a southern province in China, since the disease was first incorporated into the mandatory reporting system in 1995. Spatial autocorrelation statistics were used to correlate municipal-level clustering of reported primary syphilis cases and gross domestic product (GDP). A total of 52,036 primary syphilis cases were reported over the period 1995-2008, and the primary syphilis cases increased from 0.88 per 100,000 population in 1995 to 7.61 per 100,000 in 2008. The Pearl River Delta region has a disproportionate share (44.7%) of syphilis cases compared to other regions. Syphilis cases were spatially clustered (p = 0.01) and Moran's I analysis found that syphilis cases were clustered in municipalities with higher GDP (p = 0.004). Primary syphilis cases continue to increase in Guangdong Province, especially in the Pearl River Delta region. Considering the economic impact of syphilis and its tendency to spatially cluster, expanded syphilis testing in specific municipalities and further investigating the costs and benefits of syphilis screening are critical next steps.

Case report. Little evidence exists about impairments and perceived disability following eversion injury to the deltoid ligament. This case study prospectively examined the neuromuscular, biomechanical, and psychological consequences of a case of a medial ankle sprain. A recreationally active man with a history of a lateral ankle sprain (grade I) was participating in a university Institutional Review Board-approved research study examining the neuromuscular and mechanical characteristics associated with chronic ankle instability. Twenty-two days after the testing session, the participant sustained an eversion injury to his left ankle while playing basketball. Outcomes The outcomes of this case are presented using the International Classification of Functioning, Disability and Health model. Outcome variables were assessed at preinjury (medial ankle sprain), 3 months postinjury, and 5 months postinjury. Measurements included neural excitability of the soleus, balance assessment, joint stability, and psychological assessments. Data from this case study revealed that a medial ankle sprain reduces joint mobility and alters neural excitability of the soleus, with concurrent deficits in balance and self-reported function. These impairments forced the participant to downgrade his physical activity lifestyle up to 5 months postinjury. These data suggest the need for the development of intervention strategies to address impairments in neural excitability and joint mobility at the ankle to help patients meet the goal of maintaining long-term joint health.

To describe a series of extrarectal lymphogranuloma venereum (LGV) cases diagnosed in France. Consecutive LGV cases confirmed at the French Reference Centre for chlamydiae with an extrarectal sample from January 2010 to December 2015 were included. The first part of the study consisted of a retrospective case note review and analysis. In a second part, the complete omp A gene sequence of our samples was determined. There were 56 cases overall: 50 cases of genital LGV and six cases of pharyngeal LGV. Subjects were all men, median age 39 years, 27/53 were HIV-positive, 47/51 reported having sex with other men, 43/49 reported multiple sexual partners (a mean 25 in the last 6 months). Median time from symptom onset to diagnosis was 21 days. Subjects most commonly presented with inguinal adenopathy alone (19 of 50 genital cases) and adenopathy with genital ulcer (17 of 50). Three pharyngeal cases were symptomatic. Fever was reported in 11 cases. Inguinal abscess was reported in 22 of 42 cases presenting with lymphadenopathy. Co-infections were frequent: eight cases of syphilis, four non-LGV Chlamydia trachomatis infections, one case of gonorrhoea. Cure was always achieved with doxycycline therapy but prolonged treatment was necessary in eight cases with inguinal abscess. Genotyping according to omp A sequencing showed the co-circulation of genovars L2 (16 of 42 strains successfully typed) and L2b (24 of 42). There was no association between HIV status and disease severity or genovar distribution. In the span of 6 years, 56 extrarectal LGV cases were confirmed through genotyping in France. Extrarectal LGV seemed to share a common epidemiological background with rectal disease in terms of affected population and genovar distribution. HIV prevalence was lower than expected. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

SU-E-T-511: Inter-Rater Variability in Classification of Incidents in a New Incident Reporting System

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pappas, D; Reis, S; Ali, A

Purpose To determine how consistent the results of different raters are when reviewing the same cases within the Radiation Oncology Incident Learning System (ROILS). Methods Three second-year medical physics graduate students filled out incident reports in spreadsheets set up to mimic ROILS. All students studied the same 33 cases and independently entered their assessments, for a total of 99 reviewed cases. The narratives for these cases were obtained from a published International Commission on Radiological Protection (ICRP) report which included shorter narratives selected from the Radiation Oncology Safety Information System (ROSIS) database. Each category of questions was reviewed to seemore » how consistent the results were by utilizing free-marginal multirater kappa analysis. The percentage of cases where all raters shared full agreement or full disagreement was recorded to show which questions were answered consistently by multiple raters for a given case. The consistency among the raters was analyzed between ICRP and ROSIS cases to see if either group led to more reliable results. Results The categories where all raters agreed 100 percent in their choices were the event type (93.94 percent of cases 0.946 kappa) and the likelihood of the event being harmful to the patient (42.42 percent of cases 0.409 kappa). The categories where all raters disagreed 100 percent in their choices were the dosimetric severity scale (39.39 percent of cases 0.139 kappa) and the potential future toxicity (48.48 percent of cases 0.205 kappa). ROSIS had more cases where all raters disagreed than ICRP (23.06 percent of cases compared to 15.58 percent, respectively). Conclusion Despite reviewing the same cases, the results among the three raters was widespread. ROSIS narratives were shorter than ICRP, which suggests that longer narratives lead to more consistent results. This study shows that the incident reporting system can be optimized to yield more consistent results.« less

Background Zoonoses are common causes of human and livestock illness in Tanzania. Previous studies have shown that brucellosis, leptospirosis, and Q fever account for a large proportion of human febrile illness in northern Tanzania, yet they are infrequently diagnosed. We conducted this study to assess awareness and knowledge regarding selected zoonoses among healthcare providers in Moshi, Tanzania; to determine what diagnostic and treatment protocols are utilized; and obtain insights into contextual factors contributing to the apparent under-diagnosis of zoonoses. Methodology/Results We conducted a questionnaire about zoonoses knowledge, case reporting, and testing with 52 human health practitioners and 10 livestock health providers. Immediately following questionnaire administration, we conducted semi-structured interviews with 60 of these respondents, using the findings of a previous fever etiology study to prompt conversation. Sixty respondents (97%) had heard of brucellosis, 26 (42%) leptospirosis, and 20 (32%) Q fever. Animal sector respondents reported seeing cases of animal brucellosis (4), rabies (4), and anthrax (3) in the previous 12 months. Human sector respondents reported cases of human brucellosis (15, 29%), rabies (9, 18%) and anthrax (6, 12%). None reported leptospirosis or Q fever cases. Nineteen respondents were aware of a local diagnostic test for human brucellosis. Reports of tests for human leptospirosis or Q fever, or for any of the study pathogens in animals, were rare. Many respondents expressed awareness of malaria over-diagnosis and zoonoses under-diagnosis, and many identified low knowledge and testing capacity as reasons for zoonoses under-diagnosis. Conclusions This study revealed differences in knowledge of different zoonoses and low case report frequencies of brucellosis, leptospirosis, and Q fever. There was a lack of known diagnostic services for leptospirosis and Q fever. These findings emphasize a need for improved diagnostic capacity alongside healthcare provider education and improved clinical guidelines for syndrome-based disease management to provoke diagnostic consideration of locally relevant zoonoses in the absence of laboratory confirmation.

Efficient communication of a clinical study protocol and case report forms during all stages of a human clinical study is important for many stakeholders. An electronic and structured study representation format that can be used throughout the whole study life-span can improve such communication and potentially lower total study costs. The most relevant standard for representing clinical study data, applicable to unregulated as well as regulated studies, is the Operational Data Model (ODM) in development since 1999 by the Clinical Data Interchange Standards Consortium (CDISC). ODM's initial objective was exchange of case report forms data but it is increasingly utilized in other contexts. An ODM extension called Study Design Model, introduced in 2011, provides additional protocol representation elements. Using a case study approach, we evaluated ODM's ability to capture all necessary protocol elements during a complete clinical study lifecycle in the Intramural Research Program of the National Institutes of Health. ODM offers the advantage of a single format for institutions that deal with hundreds or thousands of concurrent clinical studies and maintain a data warehouse for these studies. For each study stage, we present a list of gaps in the ODM standard and identify necessary vendor or institutional extensions that can compensate for such gaps. The current version of ODM (1.3.2) has only partial support for study protocol and study registration data mainly because it is outside the original development goal. ODM provides comprehensive support for representation of case report forms (in both the design stage and with patient level data). Inclusion of requirements of observational, non-regulated or investigator-initiated studies (outside Food and Drug Administration (FDA) regulation) can further improve future revisions of the standard.

Rheumatoid arthritis (RA) research using large databases is limited by insufficient case validity. Of 161,808 postmenopausal women in the Women's Health Initiative, 15,691 (10.2%) reported having RA, far higher than the expected 1% population prevalence. Since chart review for confirmation of an RA diagnosis is impractical in large cohort studies, the current study (2009-2011) tested the ability of baseline serum measurements of rheumatoid factor and anti-cyclic citrullinated peptide antibodies, second-generation assay (anti-CCP2), to identify physician-validated RA among the chart-review study participants with self-reported RA (n = 286). Anti-CCP2 positivity had the highest positive predictive value (PPV) (80.0%), and rheumatoid factor positivity the lowest (44.6%). Together, use of disease-modifying antirheumatic drugs and anti-CCP2 positivity increased PPV to 100% but excluded all seronegative cases (approximately 15% of all RA cases). Case definitions inclusive of seronegative cases had PPVs between 59.6% and 63.6%. False-negative results were minimized in these test definitions, as evidenced by negative predictive values of approximately 90%. Serological measurements, particularly measurement of anti-CCP2, improved the test characteristics of RA case definitions in the Women's Health Initiative.

A guide to writing case reports for the Journal of Medical Case Reports and BioMed Central Research Notes

PubMed Central

2013-01-01

Case reports are a time-honored, important, integral, and accepted part of the medical literature. Both the Journal of Medical Case Reports and the Case Report section of BioMed Central Research Notes are committed to case report publication, and each have different criteria. Journal of Medical Case Reports was the world’s first international, PubMed-listed medical journal devoted to publishing case reports from all clinical disciplines and was launched in 2007. The Case Report section of BioMed Central Research Notes was created and began publishing case reports in 2012. Between the two of them, thousands of peer-reviewed case reports have now been published with a worldwide audience. Authors now also have Cases Database, a continually updated, freely accessible database of thousands of medical case reports from multiple publishers. This informal editorial outlines the process and mechanics of how and when to write a case report, and provides a brief look into the editorial process behind each of these complementary journals along with the author’s anecdotes in the hope of inspiring all authors (both novice and experienced) to write and continue writing case reports of all specialties. Useful hyperlinks are embedded throughout for easy and quick reference to style guidelines for both journals. PMID:24283456

Validity of using linked hospital and police traffic crash records to analyse motorcycle injury crash characteristics.

Wilson, Suzanne J; Begg, Dorothy J; Samaranayaka, Ari

2012-11-01

Linking hospital discharge and police traffic crash records has been used to provide information on causes and outcomes for hospitalised traffic crash cases. Motorcyclists are particularly vulnerable to injury in a traffic crash, but no published linkage studies have reported in detail on this road user group. The present study examined motorcycle traffic crash injury cases in New Zealand in 2000-2004 by probabilistically linking national hospital discharge records with police traffic crash reports. Injury cases had to have spent at least one night in hospital before being discharged and were defined as serious or moderate based on their International Classification of Disease Injury Severity Scores (ICISS). Despite a robust linkage process, only 46% of cases could be linked to a police record; 60% of the serious injuries and 41% of the moderate. The low linkage was most likely due to under-reporting of crashes to or by the police. While moderate injury cases were expected to be under-reported, the level of under-reporting of cases with serious threat-to-life injuries is concerning. To assess whether the linked dataset could provide valid information on the crash circumstances and injury outcomes of hospitalised motorcycle crash cases, the characteristics of the linked and unlinked hospital discharge cases were compared using chi-square tests and multivariate logistic regression. Serious injury cases were less likely to be linked if only one vehicle was involved, or the injured riders and passengers were younger than 20 years or spent less than one week in hospital. For moderate injury cases, there were also differences in linkage by injured body region and crash month. While these discrepancies need to taken into consideration when interpreting results, the linked hospital-police dataset has the potential to provide insights into motorcycle crash circumstances and outcomes not otherwise obtainable.

Toxic epidermal necrolysis (TEN) and Stevens-Johnson Syndrome (SJS) are rare, acute, life-threatening dermatologic disorders involving the skin and mucous membranes. Research into these conditions is hampered by a lack of standardization of case reporting and data collection. To establish a standardized case report form to facilitate comparisons and maintain data quality based on an international panel of SJS/TEN experts who performed a Delphi consensus-building exercise. The elements presented for committee scrutiny were adapted from previous case report forms and from PubMed literature searches of highly cited manuscripts pertaining to SJS/TEN. The expert opinions and experience of the members of the consensus group were included in the discussion. Overall, 21 out of 29 experts who were invited to participate in the online Delphi exercise agreed to participate. Surveys at each stage were administered via an online survery software tool. For the first 2 Delphi rounds, results were analyzed using the Interpercentile Range Adjusted for Symmetry method and statements that passed consensus formulated a new case report form. For the third Delphi round, the case report form was presented to the committee, who agreed that it was "appropriate and useful" for documenting cases of SJS/TEN, making it more reliable and valuable for future research endeavors. With the consensus of international experts, a case report form for SJS/TEN has been created to help standardize the collection of patient information in future studies and the documentation of individual cases.

Abstract BACKGROUND: There is little detailed epidemiologic and clinical data about tuberculosis (TB) disease in children in Canada. OBJECTIVES: This study characterizes the epidemiologic, clinical, and treatment data for all cases of TB in children under age 15 in Canada surveyed through the Canadian Pediatric Surveillance Program’s (CPSP) Childhood Tuberculosis Study. Preliminary results from the study from October 2013 to September 2016 are presented here, as data collection from reported cases is still ongoing. DESIGN/METHODS: New active TB cases were identified through a monthly form sent by the CPSP to approximately 2500 active pediatricians, pediatric subspecialists, and select non-pediatricians who manage childhood TB. For cases meeting inclusion criteria, a detailed questionnaire was sent to the treating physician to collect clinical, epidemiological, and treatment data, followed by 6-month follow-up surveys until 6 months after treatment completion. RESULTS: Of 248 unique incident cases reported, 142 cases both met inclusion criteria and returned a detailed questionnaire. Selected demographic data are shown here: Intrathoracic TB was reported in 129/142 (91%) of cases of which 111 had pulmonary disease. Of 104 patients who underwent investigations for pulmonary disease (sputum in 60, brochoalveolar lavage in 6, and gastric aspirates in 56), one or more positive cultures were obtained in 42 (40%). Within age groups, the proportion of cases who underwent investigation for pulmonary disease and were culture positive was: 3/11 (27%) under 1 year of age, 14/40 (35%) 1-4 years old, 8/23 (35%) 5-9 years old, and 17/30 (57%) 10 years or older. Extrathoracic TB was reported in 35 (25%), including 16 (42%) patients 10+ years old. There was one case of multi-drug resistant TB. CONCLUSION: Preliminary results from this study suggests a high incidence of TB in Inuit and First Nations children, as well as a higher proportion of extrathoracic TB and greater success in culture positivity in children aged 10+. At completion, this study will provide the most complete picture of childhood TB in Canada and will serve to refine practice in monitoring, detecting, and treating this infection.

Background Scrub typhus is endemic in the Asia-Pacific region including China, and the number of reported cases has increased dramatically in the past decade. However, the spatial-temporal dynamics and the potential risk factors in transmission of scrub typhus in mainland China have yet to be characterized. Objective This study aims to explore the spatiotemporal dynamics of reported scrub typhus cases in mainland China between January 2006 and December 2014, to detect the location of high risk spatiotemporal clusters of scrub typhus cases, and identify the potential risk factors affecting the re-emergence of the disease. Method Monthly cases of scrub typhus reported at the county level between 2006 and 2014 were obtained from the Chinese Center for Diseases Control and Prevention. Time-series analyses, spatiotemporal cluster analyses, and spatial scan statistics were used to explore the characteristics of the scrub typhus incidence. To explore the association between scrub typhus incidence and environmental variables panel Poisson regression analysis was conducted. Results During the time period between 2006 and 2014 a total of 54,558 scrub typhus cases were reported in mainland China, which grew exponentially. The majority of cases were reported each year between July and November, with peak incidence during October every year. The spatiotemporal dynamics of scrub typhus varied over the study period with high-risk clusters identified in southwest, southern, and middle-eastern part of China. Scrub typhus incidence was positively correlated with the percentage of shrub and meteorological variables including temperature and precipitation. Conclusions The results of this study demonstrate areas in China that could be targeted with public health interventions to mitigate the growing threat of scrub typhus in the country. PMID:27479297

The 2007 report “Toxicity Testing in the 21st Century: A Vision and A Strategy” argued for a change in toxicity testing for environmental agents and discussed federal funding mechanisms that could be used to support this transformation within the USA. The new approach would test for in vitro perturbations of toxicity pathways using human cells with high throughput testing platforms. The NRC report proposed a deliberate timeline, spanning about 20 years, to implement a wholesale replacement of current in-life toxicity test approaches focused on apical responses with in vitro assays. One approach to accelerating implementation is to focus on well-studied prototype compounds with known toxicity pathway targets. Through a series of carefully executed case studies with four or five pathway prototypes, the various steps required for implementation of an in vitro toxicity pathway approach to risk assessment could be developed and refined. In this article, we discuss alternative approaches for implementation and also outline advantages of a case study approach and the manner in which the cases studies could be pursued using current methodologies. A case study approach would be complementary to recently proposed efforts to map the human toxome, while representing a significant extension toward more formal risk assessment compared to the profiling and prioritization approaches offered by programs such as the EPA’s ToxCast effort.

2017-10-01

Transsphenoidal surgery is the gold standard for pituitary adenoma resection. However, despite advances in microsurgical and endoscopic techniques, some pituitary adenomas can be challenging to cure. We sought to determine whether, in patients undergoing transsphenoidal surgery for pituitary adenoma, intraoperative ultrasound is a safe and effective technologic adjunct. The PubMed database was searched between January 1996 and January 2016 to identify relevant publications that 1) featured patients undergoing transsphenoidal surgery for pituitary adenoma, 2) used intraoperative ultrasound, and 3) reported on safety or effectiveness. Reference lists were also checked, and expert opinions were sought to identify further publications. Ultimately, 10 studies were included, comprising 1 cohort study, 7 case series, and 2 case reports. One study reported their prototype probe malfunctioned, leading to false-positive results in 2 cases, and another study' prototype probe was too large to safely enter the sphenoid sinus in 2 cases. Otherwise, no safety issues directly related to use of intraoperative ultrasound were reported. In the only comparative study, remission occurred in 89.7% (61/68) of patients with Cushing disease in whom intraoperative ultrasound was used, compared with 83.8% (57/68) in whom it was not. All studies reported that surgeons anecdotally found intraoperative ultrasound helpful. Although there is limited and low-quality evidence available, the use of intraoperative ultrasound appears to be a safe and effective technologic adjunct to transsphenoidal surgery for pituitary adenoma. Advances in ultrasound technology may allow for more widespread use of such devices. Copyright © 2017 Elsevier Inc. All rights reserved.

Extracting information from the text of electronic medical records to improve case detection: a systematic review

2016-01-01

Background Electronic medical records (EMRs) are revolutionizing health-related research. One key issue for study quality is the accurate identification of patients with the condition of interest. Information in EMRs can be entered as structured codes or unstructured free text. The majority of research studies have used only coded parts of EMRs for case-detection, which may bias findings, miss cases, and reduce study quality. This review examines whether incorporating information from text into case-detection algorithms can improve research quality. Methods A systematic search returned 9659 papers, 67 of which reported on the extraction of information from free text of EMRs with the stated purpose of detecting cases of a named clinical condition. Methods for extracting information from text and the technical accuracy of case-detection algorithms were reviewed. Results Studies mainly used US hospital-based EMRs, and extracted information from text for 41 conditions using keyword searches, rule-based algorithms, and machine learning methods. There was no clear difference in case-detection algorithm accuracy between rule-based and machine learning methods of extraction. Inclusion of information from text resulted in a significant improvement in algorithm sensitivity and area under the receiver operating characteristic in comparison to codes alone (median sensitivity 78% (codes + text) vs 62% (codes), P = .03; median area under the receiver operating characteristic 95% (codes + text) vs 88% (codes), P = .025). Conclusions Text in EMRs is accessible, especially with open source information extraction algorithms, and significantly improves case detection when combined with codes. More harmonization of reporting within EMR studies is needed, particularly standardized reporting of algorithm accuracy metrics like positive predictive value (precision) and sensitivity (recall).

Clinical rickets has not been reported previously in Embu district, Kenya. Baseline clinical assessments performed for a nutrition intervention study in preschool children (n=324) identified 28 cases of rickets (8.6% of study sample). Clinical characteristics included: delays of sitting, walking, and teething; bone and chest deformities; widened wrists and ankles; and bowed lower extremities. Risk factors identified were short duration of breastfeeding with feeding of cereal-based supplements with little or no milk, low calcium intake, limited sunlight exposure. Vitamin D and calcium deficiencies likely contributed to these cases. Treatment with Vitamin D3 and milk resulted in clinical improvement.

Study Design Case report and literature review. Objective Spinal subdural hematomas are rare events that often progress with severe neurologic deficits. Although there have been several case reports in the literature of spontaneous spinal subdural hematomas in the setting of anticoagulation, antiplatelet therapy, or coagulation disorders, the exact pathophysiology of such phenomena remains obscure. Methods We present the first report of a subdural hematoma after a percutaneous vertebroplasty and provide a comprehensive review on the anatomy of venous drainage of the vertebral bodies with emphasis on the possible effects of venous congestion caused by cement obstruction. Results Because the subdural hematoma occurred in the absence of major cement extravasation to the spinal canal and two levels above the site of the vertebroplasty, we discuss the possible role of venous congestion as the main etiologic factor leading to rupture of the fragile, valveless radiculomedullary veins into the subdural space. Conclusions The reported case supports a possible new pathophysiological scheme for the development of spinal subdural hematoma in which venous congestion plays a pivotal etiologic role. The reported findings suggests that future anatomical and histologic studies investigating the response of the radiculomedullary veins to congestive venous hypertension may shed new light into the pathophysiology of spinal subdural hematomas.

Introduction Under-reporting of pertussis cases is a longstanding challenge. We estimated the true number of pertussis cases in Ontario using multiple data sources, and evaluated the completeness of each source. Methods We linked data from multiple sources for the period 2009 to 2015: public health reportable disease surveillance data, public health laboratory data, and health administrative data (hospitalizations, emergency department visits, and physician office visits). To estimate the total number of pertussis cases in Ontario, we used a three-source capture-recapture analysis stratified by age (infants, or aged one year and older) and adjusting for dependency between sources. We used the Bayesian Information Criterion to compare models. Results Using probable and confirmed reported cases, laboratory data, and combined hospitalizations/emergency department visits, the estimated total number of cases during the six-year period amongst infants was 924, compared with 545 unique observed cases from all sources. Using the same sources, the estimated total for those aged 1 year and older was 12,883, compared with 3,304 observed cases from all sources. Only 37% of infants and 11% for those aged 1 year and over admitted to hospital or seen in an emergency department for pertussis were reported to public health. Public health reporting sensitivity varied from 2% to 68% depending on age group and the combination of data sources included. Sensitivity of combined hospitalizations and emergency department visits varied from 37% to 49% and of laboratory data from 1% to 50%. Conclusions All data sources contribute cases and are complementary, suggesting that the incidence of pertussis is substantially higher than suggested by routine reports. The sensitivity of different data sources varies. Better case identification is required to improve pertussis control in Ontario. PMID:29718945

Intestinal stomas have a major impact on Cases' lives. It is essential to better understand the areas in which interventions may help to minimize the negative consequences. This was a case-control survey study using validated instruments (City of Hope Quality of Life-Ostomy and Short Form 36 for Veterans). Cases were accrued from Veterans Affairs Medical Centers in Tucson, Indianapolis, and Los Angeles. Eligibility included a major intra-abdominal surgical procedure that led to an ostomy (cases), or a similar procedure that did not mandate a stoma (controls). Analysis included quantitative and qualitative responses. The response rate was 48 percent (511/1,063). Cases and controls had relatively similar demographic characteristics. Because of low numbers of female respondents (13 cases and 11 controls), only results for males are reported. Based on both the City of Hope Quality of Life-Ostomy and Short Form 36 for Veterans, cases reported significantly poorer scores on scales/domains reflecting psychologic and social functioning and well being. Additionally, cases reported poorer scores on Short Form 36 for Veterans scales reflecting physical functioning and significantly lower scores on multiple items in the social domain of the City of Hope Quality of Life-Ostomy compared with controls. Two-thirds of cases replied to an open-ended question on their "greatest challenge" related to their ostomy, which led to further clarification of major issues. Multiple health-related quality of life problems were reported by male veterans with intestinal stomas. The greatest differences between cases and controls were observed in the social and psychologic domains/scales. Findings from this study provide a greater understanding of the challenges faced by ostomates and will inform the development and evaluation of urgently needed intervention strategies.

Purpose The aim of this study was to evaluate the added utility of embedding images for findings described in radiology text reports to referring clinicians. Methods Thirty-five cases referred for abdominal CT scans in 2007 and 2008 were included. Referring physicians were asked to view text-only reports, followed by the same reports with pertinent images embedded. For each pair of reports, a questionnaire was administered. A 5-point, Likert-type scale was used to assess if the clinical query was satisfactorily answered by the text-only report. A “yes-or-no” question was used to assess whether the report with images answered the clinical query better; a positive answer to this question generated “yes-or-no” queries to examine whether the report with images helped in making a more confident decision on management, whether it reduced time spent in forming the plan, and whether it altered management. The questionnaire asked whether a radiologist would be contacted with queries on reading the text-only report and the report with images. Results In 32 of 35 cases, the text-only reports satisfactorily answered the clinical queries. In these 32 cases, the reports with attached images helped in making more confident management decisions and reduced time in planning management. Attached images altered management in 2 cases. Radiologists would have been consulted for clarifications in 21 and 10 cases on reading the text-only reports and the reports with embedded images, respectively. Conclusions Providing relevant images with reports saves time, increases physicians' confidence in deciding treatment plans, and can alter management. PMID:20193926

Ciguatera fish poisoning is a potentially life-threatening disease caused by eating coral reef fish contaminated with ciguatoxins and is the most common marine poisoning. However, existing surveillance systems capture few cases. To improve regional ciguatera surveillance in South Florida, this study compared ciguatera illnesses in the Florida Poison Information Center-Miami (FPICM) call database to ciguatera cases in the Florida Department of Health (FDOH) disease surveillance systems. Univariate and multivariate logistic regression were used to identify predictors of when FPICM reported ciguatera illnesses to FDOH and whether FDOH confirmed reported ciguatera cases. FPICM staff preferentially reported ciguatera illnesses that were of shorter duration (adjusted odds ratio [AOR] = 0.84 per additional illness day; 95% confidence interval [CI] 0.74, 0.97); outbreak-associated (AOR = 7.0; 95% CI 2.5, 19.5); and clinically more severe (AOR = 21.6; 95% CI 2.3, 198.5). Among ciguatera illnesses reported to FDOH, outbreak-associated illnesses were more likely than single, sporadic illnesses to become confirmed surveillance cases (crude OR = 11.1; 95% CI 2.0, 62.5). The over-representation of outbreak-associated ciguatera cases underestimates the true contribution of sporadic illnesses to ciguatera disease burden. This bias should be considered when evaluating surveillance systems that include both outbreak-associated and sporadic illness reports.

The aim of this study was to report the findings of a qualitative case study that investigated abused women's experiences of an identification and referral intervention and to discuss the implications for nurses, specifically those working in primary and community care. Domestic violence and abuse is a significant public health issue globally but it is a hidden problem that is under-reported. In the UK, Identification and Referral to Improve Safety is a primary care-based intervention that has been found to increase referral rates of abused women to support and safety services. This paper reports on the findings of an evaluation study of two sites in England. Qualitative study with a case study design. In line with case study design, the entire evaluation study employed multiple data collection methods. We report on the qualitative interviews with women referred through the programme. The aim was to elicit their experiences of the three aspects of the intervention: identification; referral; safety. Data collection took place March 2016. Ten women took part. Eight had exited the abusive relationship but two remained with the partner who had perpetrated the abuse. Women were overwhelmingly positive about the programme and irrespective of whether they had remained or exited the relationship all reported perceptions of increased safety and improved health. Nurses have an important role to play in identifying domestic violence and abuse and in referral and safety planning. As part of a portfolio of domestic violence and abuse interventions, those that empower women to take control of their safety (such as Identification and Referral to Improve Safety) are important. © 2017 John Wiley & Sons Ltd.

Child maltreatment is a costly social issue, both financially and in terms of children's well-being. All 50 states and many countries have enacted mandatory reporting laws, but not all of them require mandated reporter training. A multitude of studies have shown that many mandated reporters do not report all of the cases of suspected child abuse…

Several studies have suggested that the likelihood of paresthesia may depend on the local anesthetic used. The purpose of this study was to determine if the type of local anesthetic administered had any effect on reports of paresthesia in dentistry in the United States. The authors obtained reports of paresthesia involving dental local anesthetics during the period from November 1997 through August 2008 from the U.S. Food and Drug Administration Adverse Event Reporting System. They used chi(2) analysis to compare expected frequencies, on the basis of U.S. local anesthetic sales data, with observed reports of oral paresthesia. During the study period, 248 cases of paresthesia occurring after dental procedures were reported. Most cases (94.5 percent) involved mandibular nerve block. The lingual nerve was affected in 89.0 percent of cases. Reports involving 4 percent prilocaine and 4 percent articaine were 7.3 and 3.6 times, respectively, greater than expected (chi(2), P < .0001) on the basis of local anesthetic use by U.S. dentists. These data suggest that paresthesia occurs more commonly after use of 4 percent local anesthetic formulations. These findings are consistent with those reported in a number of studies from other countries. Until further research indicates otherwise, dentists should consider these results when assessing the risks and benefits of using 4 percent local anesthetics for mandibular block anesthesia.

PFS is often used as a surrogate endpoint for OS in metastatic breast cancer studies. We have evaluated the association of treatment effect on PFS with significant HR OS (and how this association is affected by other factors) in published prospective metastatic breast cancer studies. A systematic literature search in PubMed identified prospective metastatic breast cancer studies. Treatment effects on PFS were determined using hazard ratio (HR PFS ), increase in median PFS (ΔMED PFS ) and % increase in median PFS (%ΔMED PFS ). Diagnostic accuracy of PFS measures (HR PFS , ΔMED PFS and %ΔMED PFS ) in predicting significant HR OS was assessed using receiver operating characteristic (ROC) curves and classification tree approach (CART). Seventy-four cases (i.e., treatment to control comparisons) from 65 individual publications were identified for the analyses. Of these, 16 cases reported significant treatment effect on HR OS at 5% level of significance. Median number of deaths reported in these cases were 153. Area under the ROC curve (AUC) for diagnostic measures as HR PFS , ΔMED PFS and %ΔMED PFS were 0.69, 0.70 and 0.75, respectively. Classification tree results identified %ΔMED PFS and number of deaths as diagnostic measure for significant HR OS . Only 7.9% (3/39) cases with ΔMED PFS shorter than 48.27% reported significant HR OS . There were 7 cases with ΔMED PFS of 48.27% or more and number of deaths reported as 227 or more - of these 5 cases reported significant HR OS . %ΔMED PFS was found to be a better diagnostic measure for predicting significant HR OS . Our analysis results also suggest that consideration of total number of deaths may further improve its diagnostic performance. Based on our study results, the studies with 50% improvement in median PFS are more likely to produce significant HR OS if the total number of OS events at the time of analysis is 227 or more.

Can cognitive exercises help treat anorexia nervosa?

PubMed

Tchanturia, K; Whitney, J; Treasure, J

2006-12-01

Cognitive remediation therapy (CRT) is used as an intervention for people with brain lesions and psychosis. This case report demonstrates the possible benefits of introducing CRT into treatment packages for anorexia nervosa (AN). In our previous work, we reported that people with AN demonstrate inflexibility in cognitive set-shifting tasks. Weight gain alone does not improve the neuropsychological profile in set-shifting tasks. This case report illustrates how training programmes can address problems in cognitive rigidity. We acknowledge the limitations of case studies, however, this is a starting point in exploring the possibilities of introducing CRT as part of the treatment of AN.

Most reported sporotrichosis cases came from South American countries, the USA, India and Japan. This mycosis is also endemic in Northeast China. However, the situation is not clear for international researchers due to lack of large series reported in English. To report and analyse 457 sporotrichosis cases. Retrospective study of 457 cases of sporotrichosis diagnosed by fungal culture at the First Hospital of Jilin University from 1 January 2007 to 31 December 2009. In this series, the male: female ratio was 1:1.42. Mean age was 41.2 years. Cases from age group 51-60 years accounted for most of the cases (22.54%). A total of 434 patients lived in rural areas (94.97%). The onset of symptoms in 67.61% cases happened in cold seasons (winter and spring). History of trauma presented in 133 cases (29.1%). The mean duration of the symptoms before the presentation was 6.41 months. A total of 190 (41.58%) showed lymphocutaneous form, 252 patients (55.14%) showed fixed form, 8 patients (1.75%) showed disseminated cutaneous sporotrichosis and the clinical form of 7 patients (1.53%) could not be defined. Extremities and nodules were the most frequently involved sites and founded manifestation. Main histopathology findings were suppurative granuloma, tuberculoid granuloma and mixed inflammatory granuloma. A total of 75 cases (19.74%) had fungal elements revealed by Periodic Acid-Schiff staining. Patients responded well to potassium iodide (KI), itraconazole, terbinafine and combinations of these agents with a mean course of 2.17 months to resolve. As the first report of a large series of sporotrichosis cases from China to be published in English literature, our study indicated a serious sporotrichosis endemic situation in Jilin province, Northeast China, with epidemiological and clinical characteristics similar to those of previous Chinese reports, but different from those in other countries. KI, itraconazole and terbinafine are effective for the treatment. © 2011 The Authors.

Studies have demonstrated an association between congenital heart disease (CHD) and neurodevelopmental delay. Neuroimaging studies have also demonstrated a high incidence of preoperative brain abnormalities. The aim of this study was to perform a systematic review to quantify the non-surgical risk of brain abnormalities and of neurodevelopmental delay in infants with CHD. MEDLINE, EMBASE and The Cochrane Library were searched electronically without language restrictions, utilizing combinations of the terms congenital heart, cardiac, neurologic, neurodevelopment, magnetic resonance imaging, ultrasound, neuroimaging, autopsy, preoperative and outcome. Reference lists of relevant articles and reviews were hand-searched for additional reports. Cohort and case-control studies were included. Studies reporting neurodevelopmental outcomes and/or brain lesions on neuroimaging in infants with CHD before heart surgery were included. Cases of chromosomal or genetic abnormalities, case reports and editorials were excluded. Between-study heterogeneity was assessed using the I(2) test. The search yielded 9129 citations. Full text was retrieved for 119 and the following were included in the review: 13 studies (n = 425 cases) reporting on brain abnormalities either preoperatively or in those who did not undergo congenital cardiac surgery and nine (n = 512 cases) reporting preoperative data on neurodevelopmental assessment. The prevalence of brain lesions on neuroimaging was 34% (95% CI, 24-46; I(2) = 0%) in transposition of the great arteries, 49% (95% CI, 25-72; I(2) = 65%) in left-sided heart lesions and 46% (95% CI, 40-52; I(2) =18.1%) in mixed/unspecified cardiac lesions, while the prevalence of neurodevelopmental delay was 42% (95% CI, 34-51; I(2) = 68.9). In the absence of chromosomal or genetic abnormalities, infants with CHD are at increased risk of brain lesions as revealed by neuroimaging and of neurodevelopmental delay. These findings are independent of the surgical risk, but it is unclear whether the time of onset is fetal or postnatal. Copyright © 2013 ISUOG. Published by John Wiley & Sons Ltd.

Lymphoedema and hydrocoele are the two most common clinical manifestations of lymphatic filariasis (LF). In order to effectively target morbidity management strategies, more information is rapidly needed on morbidity burden across all endemic countries. The purpose of this study was to develop and test an SMS tool (MeasureSMS) which enables trained community-based health workers to report basic information on all cases they identified. The tool was trialled in Chikwawa district, Malawi and Ahanta West district, Ghana in 2014. Salaried health surveillance assistants (HSAs) identified and reported cases in Malawi whereas volunteer community health workers (CHWs) were used in Ghana. Health workers were trained in recognising lymphoedema and hydrocoeles and submitting individual case data using MeasureSMS, after which they undertook a LF morbidity survey. After the reporting period, a random sample of reported cases was visited by a physician to verify the health workers' diagnoses. The proportion of correctly diagnosed cases i.e. the positive predictive value (PPV) was then calculated. HSAs in Malawi successfully reported 256 unique cases by SMS from 107 communities (166 hydrocoele, 88 lymphoedema, 2 with both), resulting in an estimated adult prevalence of 17.7 per 10,000 and 33.0 per 10,000 for lymphoedema and hydrocoele respectively. In Ghana, despite being less experienced in using SMS, CHWs successfully reported 360 unique cases by SMS from 33 communities (169 hydrocoele, 185 lymphoedema, 6 with both), resulting in an estimated adult prevalence of 76.9 per 10,000 and 70.5 per 10,000 adults for lymphoedema and hydrocoele respectively. The verification exercise resulted in a PPV for lymphoedema and hydrocoele diagnosis of 90 % (n = 42, 95 % CI 76.5 - 96.9) and 92 % (n = 49, 95 % CI 79.5 - 97.4) in Malawi and 94 % (n = 34, 95 % CI 78.9 %-99.0 %) and 47 % (n = 59, 35.1 %-61.7 %) in Ghana, indicating that non-invasive methods for diagnosing hydrocoeles needed to be further emphasised. The study concludes that given the appropriate education and tools, community-based health workers are exceptionally well-placed to participate in quantifying LF morbidity burden, and other NTDs with observable symptoms. This concept has the potential to enable national programmes to more effectively monitor their community impact in an efficient, timely and cost-effective way.

Concept Test of a Smoking Cessation Smart Case.

PubMed

Comello, Maria Leonora G; Porter, Jeannette H

2018-04-05

Wearable/portable devices that unobtrusively detect smoking and contextual data offer the potential to provide Just-In-Time Adaptive Intervention (JITAI) support for mobile cessation programs. Little has been reported on the development of these technologies. To address this gap, we offer a case report of users' experiences with a prototype "smart" cigarette case that automatically tracks time and location of smoking. Small-scale user-experience studies are typical of iterative product design and are especially helpful when proposing novel ideas. The purpose of the study was to assess concept acceptability and potential for further development. We tested the prototype case with a small sample of potential users (n = 7). Participants used the hardware/software for 2 weeks and reconvened for a 90-min focus group to discuss experiences and provide feedback. Participants liked the smart case in principle but found the prototype too bulky for easy portability. The potential for the case to convey positive messages about self also emerged as a finding. Participants indicated willingness to pay for improved technology (USD $15-$60 on a one-time basis). The smart case is a viable concept, but design detail is critical to user acceptance. Future research should examine designs that maximize convenience and that explore the device's ability to cue intentions and other cognitions that would support cessation. This study is the first to our knowledge to report formative research on the smart case concept. This initial exploration provides insights that may be helpful to other developers of JITAI-support technology.

Hepatoblastoma is a malignancy of young children. Low birth weight is associated with significantly increased risk of hepatoblastoma and neonatal medical exposures are hypothesized as contributors. This study represents the largest case-control study of hepatoblastoma to date and aimed to define the role of neonatal exposures in hepatoblastoma risk among low birth weight children. Incident hepatoblastoma cases who were born <2,500 g (N = 60), diagnosed between 2000 and 2008, were identified through the Children's Oncology Group. Controls were recruited through state birth registries (N = 51). Neonatal medical exposures were abstracted from medical records. Subjects from the Vermont Oxford Network were used for further comparisons, as were existing reports on neonatal medical exposures. Case-control comparisons were hindered by poor matching within birth weight strata. Cases were smaller and received more aggressive neonatal treatment compared to controls, and reflected high correlation levels between birth weight and treatments. Similar difficulty was encountered when comparing cases to Vermont Oxford Network subjects; cases were smaller and required more aggressive neonatal therapy. Furthermore, it appears hepatoblastoma cases were exposed to a greater number of diagnostic X-rays than in case series previously reported in the neonatal literature. This study presents the largest case series of hepatoblastoma in <2,500 g birth weight infants with accompanying neonatal medical exposure data. Findings confirm that birth weight is highly correlated with exposure intensity, and neonatal exposures are themselves highly correlated, which hampers the identification of a causal exposure among hepatoblastoma cases. Experimental models or genetic susceptibility testing may be more revealing of etiology. © 2014 Wiley Periodicals, Inc.

Increased capture of pediatric surgical complications utilizing a novel case-log web application to enhance quality improvement.

Documenting surgical complications is limited by multiple barriers and is not fostered in the electronic health record. Tracking complications is essential for quality improvement (QI) and required for board certification. Current registry platforms do not facilitate meaningful complication reporting. We developed a novel web application that improves accuracy and reduces barriers to documenting complications. We deployed a custom web application that allows pediatric surgeons to maintain case logs. The program includes a module for entering complication data in real time. Reminders to enter outcome data occur at key postoperative intervals to optimize recall of events. Between October 1, 2014, and March 31, 2015, frequencies of surgical complications captured by the existing hospital reporting system were compared with data aggregated by our application. 780 cases were captured by the web application, compared with 276 cases registered by the hospital system. We observed an increase in the capture of major complications when compared to the hospital dataset (14 events vs. 4 events). This web application improved real-time reporting of surgical complications, exceeding the accuracy of administrative datasets. Custom informatics solutions may help reduce barriers to self-reporting of adverse events and improve the data that presently inform pediatric surgical QI. Diagnostic study/Retrospective study.

Histological analysis on the medieval mummy in Korea.

PubMed

Shin, Dong Hoon; Youn, Minyoung; Chang, Byung Soo

2003-11-26

Recently, there have been some reports on the mummies from the medieval tombs in Korea, which were not made on purpose. Although these mummies could be an invaluable source for the studies on the physical state of medieval Koreans, there were not any reports on this subject until now. In this study, we first tried to investigate the various tissues using light- and electron-microscopic techniques. In the organs we have examined, even though the collagen fibers were profusely found within all of them, some types of cells, such as red blood cells, chondrocytes, hepatocyte and muscle cells, were also visible in various tissues. The histological characteristics of the current case seemed to be well matched with the previous study in general even though there were also somewhat different findings from the previous reports on the mummies. Although the cause of the mummification in Korea was not completely explained, we think that the cause in this case could be correlated with cultural aspects--not with natural conditions--because the mummies were only found in cases where the lime-soil barrier was maintained until their discovery, and which separated the inner space of the coffins from the outer space. As similar cases are frequently reported nowadays, invaluable data on the physical status of the medieval Koreans could be attainable if systemic investigation could be performed on similar cases which are found in the future.

Interpretation of blood concentrations of new psychoactive substances (NPS) requires comparison of the results to previously published case reports; as only a few experimental studies for these substances exist. A large number of articles representing single or multiple cases have been published for a great number of substances, making a unified overview difficult. In this review we have collected all published blood concentrations from the NPS groups classified as phenethylamines, aminoindanes, arylalkylamines, arylcyclohexylamines, and indolalkylamines, and also included unpublished results for MPA, MXE, 4-FMA, 4-FA and 4-MA analyzed in our laboratory. In total, 71 publications on 35 different drugs were summarized. For most of the drugs, the total number of reported cases was very low (≤5). For some of the synthetic drugs, however, a higher number of blood concentrations are now available; especially for 5-IT (32 reported cases in total), MPA (31 reported cases in total) and MXE (36 reported cases in total), thus the published results are more substantial. The present compilation could be a helpful tool for forensic toxicologists when blood concentrations of NPS are assessed. Copyright © 2017. Published by Elsevier B.V.

Makris, Gregory C., E-mail: g.makris09@doctors.org.uk; Patel, Rafiuddin; Little, Mark

IntroductionThe unintentional arterial placement of a central venous line can have catastrophic complications. The purpose of this systematic review is to assess and analyse the available evidence regarding the use of the various vascular closure devices (VCDs) for the management of iatrogenic thoraco-cervical arterial injuries (ITCAI).MethodsA systematic review was performed according to PRISMA guidelines.ResultsThirty-two relevant case series and case reports were identified with a total of 69 patients having being studied. In the majority of the studies, plug-based VCDs were used (81%) followed by suture-based devices (19%). The majority of studies reported successful outcomes from the use of VCDs inmore » terms of achieving immediate haemostasis without any acute complications. Long-term follow-up data were only available in nine studies with only one case of carotid pseudoaneurysm being reported after 1-month post-procedure. All other cases had no reported long-term complications. Five studies performed direct or indirect comparisons between VCDs and other treatments (open surgery or stent grafting) suggesting no significant differences in safety or effectiveness.ConclusionAlthough there is limited evidence, VCDs appear to be safe and effective for the management of ITCAIs. Further research is warranted regarding the effectiveness of this approach in comparison to surgery and in order to identify those patients who are more likely to benefit from this minimally invasive approach.« less

Neuroradiologic characteristics of astroblastoma and systematic review of the literature: 2 new cases and 125 cases reported in 59 publications.

Astroblastoma is a rare tumor of uncertain origin most commonly presenting in the cerebrum of children and young adults. The literature contains only case reports and small series regarding its radiologic features. This systematic review is the largest study of imaging findings of astroblastoma to date and serves to identify features that might differentiate it from other neoplasms. This study describes the imaging features of astroblastoma based on a systematic review of the literature and two new cases. We conducted a PubMed and Google Scholar database search that identified 59 publications containing 125 cases of pathology-confirmed astroblastoma, and we also added two new cases from our own institution. Data collected include patient age, gender, tumor location, morphology, calcifications and calvarial changes. We recorded findings on CT, MRI, diffusion-weighted imaging (DWI), MR spectroscopy, positron emission tomography (PET) and catheter angiography. Age at diagnosis ranged 0-70 years (mean 18 years; median 14 years). Female-to-male ratio was 8:1. Of 127 cases, 66 reported CT, 78 reported MRI and 47 reported both findings. Not all authors reported all features, but the tumor features reported included supratentorial in 96% (122/127), superficial in 72% (48/67), well-demarcated in 96% (79/82), mixed cystic-solid in 93% (79/85), and enhancing in 99% (78/79). On CT, 84% (26/31) of astroblastomas were hyperattenuated, 73% (27/37) had calcifications and 7 cases reported adjacent calvarial erosion. Astroblastomas were hypointense on T1-W in 58% (26/45) and on T2-W in 50% (23/46) of MRI sequences. Peritumoral edema was present in 80% (40/50) of cases but was typically described as slight. Six cases included DWI findings, with 100% showing restricted diffusion. On MR spectroscopy, 100% (5/5) showed nonspecific tumor spectra with elevated choline and decreased N-acetylaspartate (NAA). PET revealed nonspecific reduced uptake of [F-18] 2-fluoro-2-deoxyglucose ((18)F-FDG) and increased uptake of [11C]-Methionine in 100% (3/3) of cases. Catheter angiography findings (n=12) were variable, including hypervascularity in 67%, arteriovenous shunting in 33% and avascular areas in 25%. Astroblastomas occur most often in adolescent girls. Imaging often shows a supratentorial, superficial, well-defined, cystic-solid enhancing mass. On CT, most are hyperattenuated, have calcifications, and may remodel adjacent bone if superficial. MRI characteristically reveals a hypointense mass on T1-W and T2-W sequences with restricted diffusion. MR spectroscopy, PET and catheter angiography findings are nonspecific.

Objective: The aim of this study was to develop a new reporting format for endometrial cytology that would standardize the diagnostic criteria and the terminology used for reporting. Methods: In previous studies, cytoarchitectural criteria were found to be useful for the cytological assessment of endometrial lesions. To apply these criteria, an appropriate cytological specimen is imperative. In this article, the requirements of an adequate endometrial cytological specimen for the new diagnostic criteria are first discussed. Then, the diagnostic criteria, standardized on a combination of conventional and cytoarchitectural criteria, are presented. Third, terminology that could be used, not only for reporting the histopathological diagnosis, but also for providing better guidance for the gynaecologist to determine further clinical action, is introduced. The proposed reporting format was investigated using endometrial cytology of 58 cases that were cytologically underestimated or overestimated compared to the histopathological diagnosis made on the subsequent endometrial biopsy or surgical specimens. Results: Of the 58 cases, 12 were reassessed as being unsatisfactory for evaluation. Among the remaining 46 cases, 25 of the 27 cases, which had been underestimated and subsequently diagnosed as having endometrial carcinoma or a precursor stage on histopathological examination,were reassessed as recommended for endometrial biopsy. On the other hand, 19 cases overestimated by cytology were all reassessed as not requiring biopsy. Conclusions: The reporting format for endometrial cytology proposed in this article may improve diagnostic accuracy and reduce the number of patients managed inappropriately. PMID:18657157

Medico legal cases are essential component of medical practice and comprise most important constituent of emergencies. The reporting of such cases is imperative to recognize theirsocioeconomic burden on any country. The present study was conducted to scrutinize different categories of medico legal cases and characteristics of the victims at casualty department oftertiary care hospital Rawalpindi. The objective of the study was to find out the frequency ofvarious categories of medico legal cases and major characteristics ofvictims at tertiary care hospital, Rawalpindi. This was a cross-sectional study on 3105 registered cases in medico legal record of the casualty department of Benazir Bhutto hospital, Rawalpindi from January 2015 to December 2015. The hospital is located on the main road in densely populated central area of the city. The data wascollected on age, sex, month-wise distribution of various medico legal cases, weapon inflicting the injury, blunt trauma or physical assault, firearm injuries and road traffic accidents. The data thus obtained was analyzed using SPSS; observations were presented in tables and graphs. Out of all 3105 registered medico legal cases, reported cases caused by Road Traffic Accident 1230 (40%) followed by blunt injury or physical assault 966 (32%) cases, 19% by sharp weapons, 5% by poisoning, and 4% by firearm injuries. In our study out of 3105 cases, almost three quarter of victims (73%) were below 30 years of age, with a decreasing frequency beyond this age, males were predominantly inflicted 2516(81%) as compared to females 589 (19%). The reported road traffic accidents cases from urban areas were high (74%) as compared to those from rural locality (37%). In cases of blunt trauma, sharp weapon injuries and firearm injuries, there was a huge preponderance of victims from rural areas (65%), (62%) and 61% respectively, with urban cases constituting less. Road traffic injuries are one of the foremost causes of medico legal cases followed by blunt trauma and sharp weapon injuries. The emerging medico legal cases are neglected epidemic in most of the developing countries comprising a considerable public health problem.

Breast cancer metastasis to the stomach is relatively rare. Unlike infiltrating ductal carcinoma, invasive lobular carcinoma (ILC) has a high tendency to metastasize to the stomach. The present study reports a case of a 53-year-old female who had undergone a modified radical mastectomy of the left breast for ILC eight years previously and presented at the clinic seeking treatment for epigastric discomfort from sour regurgitation and belching that had persisted for one month. Gastroscopy revealed multiple apophysis lesions in the stomach, which were diagnosed as metastatic tumors to the stomach. The diagnosis was further established using histological and immunohistochemical analyses for gross cystic disease fluid protein-15, cytokeratin (CK) 7 and CK20. The patient was treated with systemic chemotherapy without surgery. During the treatment, two gastroscopy procedures revealed that the apophysis lesions in the gastric body had narrowed significantly. Few cases of breast cancer metastasizing to the stomach have been reported, particularly those that have been confirmed using gastroscopy. The present study reports a case of breast cancer metastasis to the stomach to raise awareness of the condition.

Study Design Case report. Objective The objective of this study is to report the occurrence of tophaceous gout in the lumbar spine. Methods Using a case report to illustrate the key points of gout in the spine, we provide a brief review of gout in the literature as it relates to its orthopedic and spinal manifestations as well as guidelines for management. Results This case report details the occurrence of a large and clinically significant finding of tophaceous gout in the lumbar spine in a 24-year-old man with a known history of gout and a 3-year history of progressive back pain. Conclusion A high index of suspicion can assist in diagnosis of patients presenting with back pain or neurologic findings with a history of gout. A previous history of gout (especially the presence of tophi), hyperuricemia, and the radiological characteristics presented here should aid the clinician in making the diagnosis of spinal gout. Early diagnosis has the potential to prevent the need for surgical intervention.

Guidelines about palliative sedation typically include recommendations to protect the well-being of relatives. The aim of this study was to systematically review evidence on the experiences of relatives with the practice of palliative sedation. PubMed, Embase, Web of Science, PsycINFO, and CINAHL were searched for empirical studies on relatives' experiences with palliative sedation. We investigated relatives' involvement in the decision-making and sedation processes, whether they received adequate information and support, and relatives' emotions. Of the 564 studies identified, 39 were included. The studies (30 quantitative, six qualitative, and three mixed methods) were conducted in 16 countries; three studies were based on relatives' reports, 26 on physicians' and nurses' proxy reports, seven on medical records, and three combined different sources. The 39 studies yielded a combined total of 8791 respondents or studied cases. Caregivers involved relatives in the decision making in 69%-100% of all cases (19 quantitative studies), and in 60%-100% of all cases, relatives were reported to have received adequate information (five quantitative studies). Only two quantitative studies reported on relatives' involvement in the provision of sedation. Despite the fact that the majority of relatives were reported to be comfortable with the use of palliative sedation (seven quantitative studies, four qualitative studies), several studies found that relatives were distressed by the use of sedation (five quantitative studies, five qualitative studies). No studies reported specifically about the support provided to the relatives. Relatives' experiences with palliative sedation are mainly studied from the perspective of proxies, mostly professional caregivers. The majority of relatives seems to be comfortable with the use of palliative sedation; however, they may experience substantial distress by the use of sedation.

The validity of tooth grinding measures: etiology of pain dysfunction syndrome revisited.

PubMed

Marbach, J J; Raphael, K G; Dohrenwend, B P; Lennon, M C

1990-03-01

The current study explores the proposition that a treating clinician's etiologic model influences patients' reports of tooth grinding, the validity of, and subsequent research findings relying on these measures. The investigation compares self-reports of tooth grinding and related clinical variables for 151 cases of temporomandibular pain and dysfunction syndrome (TMPDS) treated by a clinician who does not explicitly support the grinding theory of the etiology of TMPDS, and 139 healthy controls. Cases were no more likely than well controls to report ever-grinding, but were actually significantly less likely than well controls to report current grinding. They were also significantly more likely to report that a dentist had told them they ground. Findings suggest that studies using self-report, clinician-report of tooth grinding (or both) are methodologically inadequate for addressing the relationship between tooth grinding and TMPDS.

Objectives To estimate, overall and by organism, the incidence of infectious intestinal disease (IID) in the community, presenting to general practice (GP) and reported to national surveillance. Design Prospective, community cohort study and prospective study of GP presentation conducted between April 2008 and August 2009. Setting Eighty-eight GPs across the UK recruited from the Medical Research Council General Practice Research Framework and the Primary Care Research Networks. Participants 6836 participants registered with the 88 participating practices in the community study; 991 patients with UK-acquired IID presenting to one of 37 practices taking part in the GP presentation study. Main outcome measures IID rates in the community, presenting to GP and reported to national surveillance, overall and by organism; annual IID cases and GP consultations by organism. Results The overall rate of IID in the community was 274 cases per 1000 person-years (95% CI 254 to 296); the rate of GP consultations was 17.7 per 1000 person-years (95% CI 14.4 to 21.8). There were 147 community cases and 10 GP consultations for every case reported to national surveillance. Norovirus was the most common organism, with incidence rates of 47 community cases per 1000 person-years and 2.1 GP consultations per 1000 person-years. Campylobacter was the most common bacterial pathogen, with a rate of 9.3 cases per 1000 person-years in the community, and 1.3 GP consultations per 1000 person-years. We estimate that there are up to 17 million sporadic, community cases of IID and 1 million GP consultations annually in the UK. Of these, norovirus accounts for 3 million cases and 130 000 GP consultations, and Campylobacter is responsible for 500 000 cases and 80 000 GP consultations. Conclusions IID poses a substantial community and healthcare burden in the UK. Control efforts must focus particularly on reducing the burden due to Campylobacter and enteric viruses. PMID:21708822

Snippets from the past: is Flint, Michigan, the birthplace of the case-control study?

PubMed

Morabia, Alfredo

2013-12-15

In the summer of 1924, an outbreak of scarlet fever occurred in Flint, Michigan. Unable to trace it to the usual causes, particularly fresh milk, the Michigan Department of Health used a novel approach to disentangle the enigma: The 116 cases of scarlet fever were compared with 117 "controls" selected from neighbors of the quarantined cases and from patients at the City Health Center who had been treated for ailments unrelated to scarlet fever. The extraordinary culprit was ice cream, which had a frequent/occasional/none consumption prevalence of 60%, 34%, and 6% among the cases and 24%, 51%, and 25% among the controls, respectively. The 1925 report reads, "Detailed epidemiological investigation, by means of case histories and control histories on well persons, confirmed early suspicions and established the fact that the epidemic was spread by ice cream" (Am J Hyg. 1925;5(5):669-681). This forgotten epidemiologic study is the oldest study using the case-control design to have been resurrected thus far. The case-control study design may have been conceived simultaneously, but independently and for different purposes, in England (Janet Lane-Claypon's 1926 report on the determinants of breast cancer) and the United States.

Traumatic Buccal Fat Pad Herniation in Young Children: A Systematic Review and Case Report.

2017-09-01

Traumatic herniation of a buccal fat pad, predominantly seen in young children, is a rare condition. Because of its rarity and clinical features that resemble tumors, clinicians are faced with challenges at the initial diagnosis. This report describes a case of buccal fat pad herniation with excellent long-term prognosis after surgical relocation and conservative treatment and presents a systematic review of the literature on its management. Through a PubMed search, 811 articles were initially identified. Case series, case reports, technical notes, case and review reports, and retrospective case series were included. After screening and manual review, the sample was narrowed to 35 reports (41 patients) based on eligibility criteria. Articles were included if the standard criteria for traumatic intraoral herniation of buccal fat pad were met. Patients' ages ranged from 4 months to 12 years, with no specific gender predilection. Management consisted of excision (82.9%), relocation (14.6%), and observation (2.4%). Follow-up ranged from 1 week to 4 months. No reports presented a follow-up longer than 4 months; hence, data on long-term prognosis were not reported. For the present case report, a 19-month-old boy diagnosed with traumatic buccal fat pad herniation was successfully treated with surgical relocation and antibiotic support. Twelve-month follow-up showed no esthetic or functional disturbance or recurrence. Traumatic herniation of the buccal fat pad requires special attention at the initial diagnosis. Considering its clinical importance in young children and few studies have reported long-term postresection follow-up, surgical relocation can be regarded as an excellent and more conservative treatment option.

Reporting of suspicious cases of child abuse is a sensitive issue that is often hindered by uncertainty of diagnosis. This cross sectional study aimed to assess the UAE dentists' experiences in child abuse recognition, the factors that prevent them from reporting suspicious cases to authorities and their perceived training needs. A closed-ended, self-administered questionnaire was distributed to 350 dentists working in the UAE. Chi Square test was used to determine association between training needs on child abuse and its reporting rate. Logistic regression was used to determine the association between perceived training needs and other covariates. One hundred and ninety three respondents satisfied the inclusion criteria. Forty seven (25%) dentists reported encountering a suspicious child abuse case at least once in their career, but only 15 (32%) of those reported their suspicion. Fear of making the wrong diagnosis was the most frequent challenge hindering reporting and dentists who demonstrated a need for specialized training were more likely to express this fear (OR = 5.88, 95% CI: 0.07, 0.45; P = 0.00). The majority of UAE dentists do not report their suspicion to authorities and specialized training should be offered to build dentists' capacity in diagnosing and appropriately reporting suspicious child abuse cases.

Bovine thrombin safety reporting: an example of study design and publication bias.

PubMed

Crean, Sheila; Michels, Shannon L; Moschella, Kevin; Reynolds, Matthew W

2010-01-01

Bovine thrombin, a popular hemostat and sealant since 1945, has recently been subjected to clinical trial testing due to reformulations in 1998. We sought to compare adverse event rates of early observational studies with those of later interventional trials. A MEDLINE-based literature search in publications that report safety in bovine thrombin exposed surgical patients was extracted and reviewed. In 38 studies, about half were case reports and 31.5% were interventional trials. In case reports, 41% of authors reported severe coagulopathic adverse events. In contrast, whereas blood complications were common in large trials, no association of harm was established for bovine thrombin product exposure and/or immunization. In this review, later clinical trials failed to reproduce the common and severe coagulopathy predicted by earlier observational studies in bovine exposed patients. This example illustrates that perceptions of safety can change as a function of study design, even for a widely adopted, well established biologic such as thrombin. Caution must be exercised in interpreting evidence from observational studies alone.

Assessing Police Classifications of Sexual Assault Reports: A Meta-Analysis of False Reporting Rates.

PubMed

Ferguson, Claire E; Malouff, John M

2016-07-01

The objective of the study was to determine, through meta-analysis, the rate of confirmed false reports of sexual assault to police. The meta-analysis initially involved a search for relevant articles. The search identified seven studies where researchers or their trained helpers evaluated reported sexual assault cases to determine the rate of confirmed false reports. The meta-analysis calculated an overall rate and tested for possible moderators of effect size. The meta-analytic rate of false reports of sexual assault was .052 (95 % CI .030, .089). The rates for the individual studies were heterogeneous, suggesting the possibility of moderators of rate. However, the four possible moderators examined-year of publication, whether the data set used had information in addition to police reports, whether the study was completed in the U.S. or elsewhere, and whether inter-rater reliabilities were reported-were all not significant. The meta-analysis of seven relevant studies shows that confirmed false allegations of sexual assault made to police occur at a significant rate. The total false reporting rate, including both confirmed and equivocal cases, would be greater than the 5 % rate found here.

Harigane, K; Sumi, A; Mise, K; Kobayashi, N

2015-09-01

Annual periodicities of reported chickenpox cases have been observed in several countries. Of these, Japan has reported a two-peaked, bimodal annual cycle of reported chickenpox cases. This study investigated the possible underlying association of the bimodal cycle observed in the surveillance data of reported chickenpox cases with the meteorological factors of temperature, relative humidity and rainfall. A time-series analysis consisting of the maximum entropy method spectral analysis and the least squares method was applied to the chickenpox data and meteorological data of 47 prefectures in Japan. In all of the power spectral densities for the 47 prefectures, the spectral lines were observed at the frequency positions corresponding to the 1-year and 6-month cycles. The optimum least squares fitting (LSF) curves calculated with the 1-year and 6-month cycles explained the underlying variation of the chickenpox data. The LSF curves reproduced the bimodal and unimodal cycles that were clearly observed in northern and southern Japan, respectively. The data suggest that the second peaks in the bimodal cycles in the reported chickenpox cases in Japan occurred at a temperature of approximately 8·5 °C.

Methanol poisoning among travellers to Indonesia.

Giovanetti, Franco

2013-01-01

Common Travel Medicine sources generally do not provide information on the risk of methanol poisoning among travellers who visit Indonesia. The aim of this analysis was to increase knowledge on this topic through reports from bibliographic databases and Internet sources. Case reports and studies on methanol poisoning in Indonesia were retrieved through PubMed, Embase and Google Scholar database searching. The Google search was used to retrieve the Web Media articles reporting fatal and non-fatal methanol poisoning in Indonesia, in a timeframe from 01.01.2009 to 03.03.2013. Three case reports of methanol poisoning involving four travellers to Indonesia were found in bibliographic databases. The media sources searching identified 14 articles published online, reporting 22 cases of methanol poisoning among travellers after consumption of local alcohol beverages. The total number of death cases was 18. Some sources report also a large number of cases among the local population. Methanol poisoning is likely to be an emerging public health problem in Indonesia, with an associated morbidity and mortality among travellers and local people. Some strategies can be implemented to prevent or reduce harm among travellers. Copyright © 2013 Elsevier Ltd. All rights reserved.

Impact of incidental/misdiagnosed intrahepatic cholangiocarcinoma and combined hepatocellular cholangiocarcinoma on the outcomes of liver transplantation: an institutional case series and literature review.

Intrahepatic cholangiocarcinoma (ICC) or combined hepatocellular cholangiocarcinoma (cHCC-CC) is considered to be contraindications for liver transplantation (LT); however, recent studies have shown that the outcomes of LT in small incidental ICC/cHCC-CC tumors are comparable to those in HCC. Studies reporting the survival outcome of patient(s) undergoing LT and found to have incidental or misdiagnosed ICC and/or cHCC-CC in liver explants were reviewed. Our institutional data were also included in the review analysis. In this review, 21 studies reporting 19865 cases of liver transplantation were included. The incidence of misdiagnosed/incidental ICC/cHCC-CC in liver explants was found to be 0.7% (136/19636). Hepatitis B and C virus infection was reported in 19 and 47% of the cases, respectively. The recurrence rate after LT was 42%. The most common site for recurrence was extrahepatic (73%). The disease free survival rate at 3 years was reported to range 33-86%. The 3-year overall survival rate was reported be 22-70%. The outcome of LT in patients with incidental/misdiagnosed ICC/cHCC-CC was found to be poorer than that of matched patients with HCC in five studies; however, the outcome becomes equivalent to those of HCC in cases of small (<2 cm), well-differentiated ICC/cHCC-CC tumors without vascular invasion.

Drug induced hepatotoxicity: data from the Serbian pharmacovigilance database.

2011-04-01

The main aim of this study was to determine the most frequently reported drugs to the Serbian Pharmacovigilance Database (SPD) with suspected induced hepatotoxicity. Additionally, reasons for the low reporting rate of adverse drug reactions (ADRs) in Serbia were identified. Retrospective observational study of spontaneously reported ADRs recorded in the SPD from January 1995 to December 2008 was performed. The Medical Dictionary for Regulatory Activities (MedDRA) was used to identify cases of hepatobiliary disorders (HD). Drugs were classified using the Anatomical Therapeutic Chemical (ATC) classification. Medline and WHO-UMC databases were used to address specific queries suggested by our results. The questionnaire was used to investigate the health care professionals' knowledge and practice related to spontaneous reporting. Among the 1804 reports of ADRs recorded in the SPD between 1995 and 2008, 70 (3.9%) cases of HD were identified. Drugs most frequently associated with hepatotoxicity were anti-infectives for systemic use, drugs affecting the nervous system, herbal products, hypolipemics, and anticoagulant drugs (26.83, 24.39, 12.20, 9.76, and 8.54% cases, respectively). Four cases (5.71%) of liver injury resulted in death, which accounted for 10.26% of all ADR fatalities reported to the SPD. The main reasons for not reporting ADRs were lack of reporting knowledge (30.26%), well-known ADRs (29.89%), and insecurity about causality relationship (15.50%). Anti-infectives, nervous system drugs, and herbal products were the most common drug classes reported for hepatotoxicity in Serbia. There is a need for additional education about ADRs, and enhanced reporting by health care professionals. Copyright © 2011 John Wiley & Sons, Ltd.

Extended-release Methylphenidate Treatment and Outcomes in Comorbid Social Anxiety Disorder and Attention-deficit/Hyperactivity Disorder: 2 Case Reports.

PubMed

Koyuncu, Ahmet; Çelebi, Fahri; Ertekin, Erhan; Kahn, David A

2015-05-01

Social anxiety disorder is frequently comorbid with attention-deficit/hyperactivity disorder (ADHD). However, treatment recommendations are not clear in the presence of such comorbidity. A few studies in the literature have reported improvement in symptoms of both disorders with treatment specific for ADHD (ie, stimulants and atomoxetine). In this report, we present cases of 2 adults with social anxiety disorder and ADHD who were treated with methylphenidate monotherapy. Both cases responded well in terms of not only their ADHD symptoms but also the social anxiety disorder symptoms. Methylphenidate was well tolerated with no significant side effects. More studies are needed to better establish the potential of ADHD medications to be effective for comorbid social anxiety disorder symptoms.

2012-11-01

In this study, we report the first Korean case of an anti-Gerbich (Ge) alloantibody to a high-incidence antigen that belongs to the Ge blood group system. The alloantibody was detected in a middle-aged Korean woman who did not have a history of transfusion. Her blood type was B+, and findings from the antibody screening test revealed 1+ reactivity in all panels except the autocontrol. The cross-matching test showed incompatible results with all 5 packed red blood cells. Additional blood type antigen and antibody tests confirmed the anti-Ge alloantibody. While rare, cases of hemolytic transfusion reaction or hemolytic disease in newborns due to anti-Ge have been recently reported in the literature. Therefore, additional further studies on alloantibodies to high-incidence antigens, including anti-Ge, are necessary in the future.

(1) Review evidence for the use of oral diuretic medications in the management of Ménière's disease. (2) Analyze therapy-related hearing and vertigo outcomes. Literature was obtained through directed searches of MEDLINE, EMBASE, Web of Science, EBSCO Host, Cochrane Reviews, and linked citations through seminal papers. We searched independent electronic databases for articles that reported the use of diuretics in patients with Ménière's disease. All articles of level 4 evidence or higher, per the Oxford Centre for Evidence-Based Medicine, were included with no limit for number of patients, duration of therapy, or follow-up period. Two independent investigators reviewed the articles for inclusion eligibility. Outcomes were tabulated, including subjective or quantitative measures of hearing, tinnitus, vertigo episode frequency, and medication adverse effects. Nineteen articles were included from 1962 to 2012 from 11 countries. Twelve retrospective case series, 4 randomized controlled trials, 2 case-control trials, and 1 prospective case series were identified. Six studies investigated isosorbide; 5, hydrochlorothiazide; 2, acetazolamide; 2, chlorthalidone; and 1 each of betahistine, hydrochlorothiazide, chlorthalidone, acetazolamide, hydrochlorothiazide-triamterene, and nimodipine. Eight (42.1%) studies reported hearing outcomes improvement. Fifteen (79.0%) studies reported vertigo outcomes improvement. Ten (52.6%) studies reported no side effects, and 4 studies (21.1%) reported abdominal discomfort. No significant morbidity or mortality was reported in any study. Multiple low evidence-level studies report that oral diuretic therapy may be beneficial in the medical management of Ménière's disease. Improvement in vertigo episode frequency was consistently reported, with less convincing evidence for improvement in hearing outcomes. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

2016-01-01

A systematic review on laryngopyoceles across Ovid, PubMed, and Google Scholar database was conducted. A total of 61 papers published between 1952 and 2015 were found. Of these, 23 cases written in English, which described the number of cases, surgical approaches, resort to tracheostomy, complications, and outcomes, were shortlisted. Four cases of laryngopyoceles were managed endoscopically using a cold instrument, microdebrider, or laser. Eighteen cases were operated via an external approach, and 1 case applied both approaches. One of 4 endoscopic and 10 of 18 external approaches involved tracheostomy. The present study aimed to report a case of large mixed laryngopyocele that was successfully drained and marsupialized endoscopically using suction diathermy without requiring tracheostomy. Management using suction diathermy for excision and marsupialization of a laryngopyocele has never been reported and can be recommended as a feasible method due to its widespread availability. In the presence of a large laryngopyocele impeding the airway, tracheostomy may be averted in a controlled setting. None specified.

Ethical issues have been raised about using the psychological autopsy approach in the study of suicide. The impact on informants of control cases who participated in case-control psychological autopsy studies has not been investigated. (1) To investigate whether informants of suicide cases recruited by two approaches (coroners' court and public mortuaries) respond differently to the initial contact by the research team. (2) To explore the reactions, reasons for participation, and comments of both the informants of suicide and control cases to psychological autopsy interviews. (3) To investigate the impact of the interviews on informants of suicide cases about a month after the interviews. A self-report questionnaire was used for the informants of both suicide and control cases. Telephone follow-up interviews were conducted with the informants of suicide cases. The majority of the informants of suicide cases, regardless of the initial route of contact, as well as the control cases were positive about being approached to take part in the study. A minority of informants of suicide and control cases found the experience of talking about their family member to be more upsetting than expected. The telephone follow-up interviews showed that none of the informants of suicide cases reported being distressed by the psychological autopsy interviews. The acceptance rate for our original psychological autopsy study was modest. The findings of this study are useful for future participants and researchers in measuring the potential benefits and risks of participating in similar sensitive research. Psychological autopsy interviews may be utilized as an active engagement approach to reach out to the people bereaved by suicide, especially in places where the postvention work is underdeveloped.

Standardized classification unsuitable for spontaneous reporting: the example of osteonecrosis of the jaw.

PubMed

de Boissieu, Paul; Trenque, Thierry

2015-07-01

This study assessed the impact of using a standardized definition of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in the analysis of a spontaneous reporting database. All notifications of osteonecrosis of the jaw (ONJ) in the French National Pharmacovigilance Database as of 31 December 2013 were analyzed. First, we considered all reports of ONJ with bisphosphonates as BRONJ. Second, we applied the 2014 definition of BRONJ from the American Association of Oral and Maxillofacial Surgeons (AAOMS), retaining only bisphosphonates as antiresorptive medication. In the absence of any one of these criteria, or missing data, cases were not considered as BRONJ. The first analysis found 158 cases of ONJ, among which 153 were associated with bisphosphonate use. The second analysis identified only 43 cases of BRONJ (28.1%). The definition of BRONJ as laid down by the AAOMS is not suitable for use in spontaneous reporting database. The use of the AAOMS definition alone should be avoided, as it leads to the exclusion of over 70% of cases. When cases of ONJ are identified, all results should be presented including confirmed and excluded cases.

Metachromatic leukodystrophy is a rare disorder with great clinical variability. We report the first case of triplets with the late infantile form of the disease and their systematic progression of symptoms. We reviewed the literature and identified all human studies that reported new cases since 1921. We analyzed survival by decade to assess the impact of historical changes in the management of care. Mean age at death and the 5-year survival from onset of symptoms for late infantile, juvenile, and adult phenotypes were 4.2 years and 24.9%, 17.4 years and 70.3%, and 43.1 years and 88.6%, respectively. The 5-year survival of cases reported after 1990 was significantly better than cases reported before 1970 in all subtypes of metachromatic leukodystrophy (late infantile: 52% vs 14%, juvenile: 100% vs 46%, adult: 95% vs 67%). Survival in the late infantile subtype was worse than that in other subtypes. Survival significantly improved over time in all subtypes.

DK phocomelia phenotype (von Voss-Cherstvoy syndrome) caused by somatic mosaicism for del(13q).

PubMed

Bamforth, J S; Lin, C C

1997-12-31

DK phocomelia (von Voss-Cherstvoy syndrome) is a rare condition characterized by radial ray defects, occipital encephalocoele, and urogenital abnormalities. Lubinsky et al. [1994: Am J Med Genet 52:272-278] pointed out similarities between this and the del(13q) syndrome. To date, all reported cases of DK phocomelia have been apparently normal chromosomally. We report on a case of DK phocomelia in which the proposita had normal lymphocyte chromosomes, but was mosaic in fibroblasts for del(13)(q12).

Ackerman, E.; Hart, D.; Lethi, M.

The MITRE Corporation conducted a five-month study for the Office of Resource Applications in the Department of Energy on the regulatory requirements of low-Btu coal gasification. During this study, MITRE interviewed representatives of five current low-Btu coal gasification projects and regulatory agencies in five states. From these interviews, MITRE has sought the experience of current low-Btu coal gasification users in order to recommend actions to improve the regulatory process. This report is the third of three volumes. It contains the results of interviews conducted for each of the case studies. Volume 1 of the report contains the analysis of themore » case studies and recommendations to potential industrial users of low-Btu coal gasification.

We report a rare case of first branchial cleft cyst arising from the nasopharynx. A 47-year old woman with a six-month-history of right ear stuffy and hearing loss was studied. Electronic nasopharyngeal examination revealed a mass in the nasopharynx of this case. The tumor was removed endoscopically with endonasal approach. Postoperative pathological examination indicated that it was branchial cleft cyst. Copyright© by the Editorial Department of Journal of Clinical Otorhinolaryngology Head and Neck Surgery.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease that was recently identified in China, South Korea and Japan. The objective of the study was to evaluate the epidemiologic and clinical characteristics of SFTS in South Korea. SFTS is a reportable disease in South Korea. We included all SFTS cases reported to the Korea Centers for Disease Control and Prevention (KCDC) from January 2013 to December 2015. Clinical information was gathered by reviewing medical records, and epidemiologic characteristics were analyzed using both KCDC surveillance data and patient medical records. Risk factors for mortality in patients with SFTS were assessed. A total of 172 SFTS cases were reported during the study period. SFTS occurred throughout the country, except in urban areas. Hilly areas in the eastern and southeastern regions and Jeju island (incidence, 1.26 cases /105 person-years) were the main endemic areas. The yearly incidence increased from 36 cases in 2013 to 81 cases in 2015. Most cases occurred from May to October. The overall case fatality ratio was 32.6%. The clinical progression was similar to the 3 phases reported in China: fever, multi-organ dysfunction, and convalescence. Confusion, elevated C-reactive protein, and prolonged activated partial thromboplastin times were associated with mortality in patients with SFTS. Two outbreaks of nosocomial SFTS transmission were observed. SFTS is an endemic disease in South Korea, with a nationwide distribution and a high case-fatality ratio. Confusion, elevated levels of C-reactive protein, and prolonged activated partial thromboplastin times were associated with mortality in patients with SFTS.
