PubMed

Brożek-Mucha, Zuzanna; Zdeb, Krzysztof

2018-05-01

Evidence materials in a presumed suicide case were studied by a firearm examiner and a forensic chemist. The victim's body with double gunshot wounding in his forehead, a machine gun in the sustained fire mode with a silencer, and four cartridge cases were found. Examinations of the evidence, the case file studies, and experiments dedicated to the case were carried out. Relationships between the placement of cartridge cases and the gun were established using a fast camera. The distributions of gunshot residues on the evidence materials and within the comparative gunshot patterns were studied by means of optical and electron microscopy, X-ray microanalysis, and infrared spectroscopy. The shooting distance was assessed to be 30 cm or more, whereas the greatest distance that could have been achieved by the victim himself was about 11-13 cm. The obtained results supported the version of homicide rather than suicide. © 2017 American Academy of Forensic Sciences.

2017-11-01

To examine validity evidence of local graduation competency examination scores from seven medical schools using shared cases and to provide rater training protocols and guidelines for scoring patient notes (PNs). Between May and August 2016, clinical cases were developed, shared, and administered across seven medical schools (990 students participated). Raters were calibrated using training protocols, and guidelines were developed collaboratively across sites to standardize scoring. Data included scores from standardized patient encounters for history taking, physical examination, and PNs. Descriptive statistics were used to examine scores from the different assessment components. Generalizability studies (G-studies) using variance components were conducted to estimate reliability for composite scores. Validity evidence was collected for response process (rater perception), internal structure (variance components, reliability), relations to other variables (interassessment correlations), and consequences (composite score). Student performance varied by case and task. In the PNs, justification of differential diagnosis was the most discriminating task. G-studies showed that schools accounted for less than 1% of total variance; however, for the PNs, there were differences in scores for varying cases and tasks across schools, indicating a school effect. Composite score reliability was maximized when the PN was weighted between 30% and 40%. Raters preferred using case-specific scoring guidelines with clear point-scoring systems. This multisite study presents validity evidence for PN scores based on scoring rubric and case-specific scoring guidelines that offer rigor and feedback for learners. Variability in PN scores across participating sites may signal different approaches to teaching clinical reasoning among medical schools.

The utility of case formulation in treatment decision making; the effect of experience and expertise.

PubMed

Dudley, Robert; Ingham, Barry; Sowerby, Katy; Freeston, Mark

2015-09-01

We examined whether case formulation guides the endorsement of appropriate treatment strategies. We also considered whether experience and training led to more effective treatment decisions. To examine these questions two related studies were conducted both of which used a novel paradigm using clinically relevant decision-making tasks with multiple sources of information. Study one examined how clinicians utilised a pre-constructed CBT case formulation to plan treatment. Study two utilised a clinician-generated formulation to further examine the process of formulation development and the impact on treatment planning. Both studies considered the effect of therapist experience. Both studies indicated that clinicians used the case formulation to select treatment choices that were highly matched to the case as described in the vignette. However, differences between experts and novice clinicians were only demonstrated when clinicians developed their own formulations of case material. When they developed their own formulations the experts' formulations were more parsimonious, internally consistent, and contained fewer errors and the experts were less swayed by irrelevant treatment options. The nature of the experimental task, involving ratings of suitability of possible treatment options suggested for the case, limits the interpretation that formulation directs the development or generation of the clinician's treatment plan. In study two the task may still have limited the capacity to demonstrate further differences between expert and novice therapists. Formulation helps guide certain aspects of effective treatment decision making. When asked to generate a formulation clinicians with greater experience and expertise do this more effectively.

2012-05-01

To present findings from a case series of gastric dilatation (GD) or gastric dilatation and volvulus (GDV) in working farm dogs in New Zealand that were examined at veterinary clinics, and to identify possible risk factors for GD or GDV in working farm dogs in New Zealand using a case-control study. This retrospective study included a case-series and a case-control study. The case series analysed information from 62 case records of GD or GDV in working farm dogs seen between August 2004 and September 2009 at 13 veterinary clinics throughout New Zealand. Cases were classified as GD or GDV if the diagnosis was confirmed by radiography, surgery or post-mortem examination. Details of history and treatment, as well as outcomes, were obtained for each case. For the case-control study, records of 41 working farm dogs with GD or GDV (cases) seen between April 2008 and April 2009, and 82 working farm dogs examined because of trauma over the same period and in the same 13 clinics (controls), were used to model the risk factors for GD or GDV. From the case-series study, 40/62 (65%) cases of GD or GDV that were examined and treated at the veterinary clinics returned to work. Of the 41 dogs where the gastric contents were recorded, 25 (61%) had predominantly food or bones in the stomach, and 26/27 dogs had a history of having eaten meat, bones or scavenged a carcass. The case-control study showed that the significant risk factors for GD or GDV, compared with control dogs presenting with trauma, were breed, age and season. The odds that a case of GD or GDV was a Huntaway, after adjusting for age and season, was 19 times higher than the odds a control was a Huntaway. Gender and bodyweight were not identified as risk factors. A high proportion of farm working dogs with GD or GDV were successfully treated by veterinarians. The risk of a case of GD or GDV being a Huntaway was significantly higher than for a dog presenting as a trauma case. However the influences of the season of the year, climatic factors and nutritional factors on the pathogenesis need to be identified before adequate preventative measures can be recommended.

Too little, too late? Physical examinations performed by trainee psychiatrists on newly admitted psychiatric patients. To assess the comprehensiveness of the physical examination carried out by psychiatric trainees on acute in-patient units. To quantify delays in undertaking physical examination on psychiatric inpatients. A prospective case note study of 60 consecutive admissions to acute psychiatric wards in North Staffordshire. Information regarding demography, details of physical examination and routine blood investigations was collected. The case notes of 60 inpatients were studied. Mean age was 38.7 years and the sex ratio equal. A delay in performing a physical occurred in 17 (28.8%) patients. No explanation for a delay was given in six (10.0%) cases. The mean time to physical examination from admission was 61.8 h (range 0-612 h). The standard of physical examination was variable. The central nervous system (CNS) was reported as 'grossly intact' in six (10.2%) cases with only 34 (57.6%) of patients having a comprehensive CNS examination. Psychiatric patients are not receiving a comprehensive physical examination. Whilst the patient's ability to co-operate may account for a delay in the examination, it is unlikely to be the reason for the CNS being examined in just half the patients. Opportunities to reduce the physical morbidity associated with mental illness may be being lost. (MJ Psych Clin Pract 2004; 8: 57-60).

Diabetic retinopathy screening with pharmacy-based teleophthalmology in a semiurban setting: a cost-effectiveness analysis.

2016-01-01

Diabetic eye complications are the leading cause of visual loss among working-aged people. Pharmacy-based teleophthalmology has emerged as a possible alternative to in-person examination that may facilitate compliance with evidence-based recommendations and reduce barriers to specialized eye care. The objective of this study was to estimate the cost-effectiveness of mobile teleophthalmology screening compared with in-person examination (primary care) for the diabetic population residing in semiurban areas of southwestern Ontario. A decision tree was constructed to compare in-person examination (comparator program) versus pharmacy-based teleophthalmology (intervention program). The economic model was designed to identify patients with more than minimal diabetic retinopathy, manifested by at least 1 microaneurysm at examination (modified Airlie House classification grade of ≥ 20). Cost-effectiveness was assessed as cost per case detected (true-positive result) and cost per case correctly diagnosed (including true-positive and true-negative results). The cost per case detected was $510 with in-person examination and $478 with teleophthalmology, and the cost per case correctly diagnosed was $107 and $102 respectively. The incremental cost-effectiveness ratio was $314 per additional case detected and $73 per additional case correctly diagnosed. Use of pharmacologic dilation and health care specialists' fees were the most important cost drivers. The study showed that a compound teleophthalmology program in a semiurban community would be more effective but more costly than in-person examination. The findings raise the question of whether the benefits of pharmacy-based teleophthalmology in semiurban areas, where in-person examination is still available, are equivalent to those observed in remote communities. Further study is needed to investigate the impact of this program on the prevention of severe vision loss and quality of life in a semiurban setting.

Can a limited double reading/second opinion of initially recalled breast ultrasound screening examinations improve radiologists' performances?

2018-03-01

Interpretations of breast ultrasound screening examinations result in high recall rates and large inter-radiologist variability, frequently leading to "conservative" recommendations. Double reading of all breast ultrasound screening examinations is cost prohibitive, but double reading of only "initially recalled" cases may prove efficacious. We assessed changes in recommendations, if any, by providing a consensus second opinion in a limited subset of examinations initially recommended for recall. We performed a retrospective reader study with 197 ultrasound examinations (97 not recalled and 100 recalled clinically). First, we generated a consensus "second opinion" consisting of the majority vote of three independent readings of each case by experienced ultrasound interpreters. During the reader study that followed, if the reader recommended a "recall" and the "consensus second opinion" did not, a message to that effect was displayed and the reader was asked to re-review the exam and re-assess if, knowing the second opinion, a re-rating of the case was warranted. We compared performance levels pre- and post- the second opinion. The second opinion resulted in "no recall" recommendations of 141 cases in the entire set, including four cancer cases missed by all three readers. On average, radiologists received "warning" messages in 30 cases (range 15-50), or in 15% of cases. Rating changes (downgrades to no recall) occurred in 36 of these cases. These changes resulted in a possible recall rate reduction of 28% in prompted cases or 14% overall recall reduction, while increasing the false negative rate by only one case missed by 2 readers ( 1%).

The precise effect and the quality of different cases used in dermatology problem-based learning (PBL) curricula are yet unclear. To prospectively compare the impact of real patients, digital, paper PBL (PPBL) and traditional lecture-based learning (LBL) on academic results and student perceptions. A total of 120 students were randomly allocated into either real-patients PBL (RPBL) group studied via real-patient cases, digital PBL (DPBL) group studied via digital-form cases, PPBL group studied via paper-form cases, or conventional group who received didactic lectures. Academic results were assessed through review of written examination, objective structured clinical examination and student performance scores. A five-point Likert scale questionnaire was used to evaluate student perceptions. Compared to those receiving lectures only, all PBL participants had better results for written examination, clinical examination and overall performance. Students in RPBL group exhibited better overall performance than those in the other two PBL groups. Real-patient cases were more effective in helping develop students' self-directed learning skills, improving their confidence in future patient encounters and encouraging them to learn more about the discussed condition, compared to digital and paper cases. Both real patient and digital triggers are helpful in improving students' clinical problem-handling skills. However, real patients provide greater benefits to students.

PubMed

Szeredi, Levente; Jánosi, Szilárd; Pálfi, Vilmos

2010-09-01

The infectious origin of fatal cases of calf pneumonia was studied in 48 calves from 27 different herds on postmortem examination. Lung tissue samples were examined by pathological, histological, bacterial culture, virus isolation and immunohistochemical methods for the detection of viral and bacterial infections. Pneumonia was diagnosed in 47/48 cases and infectious agents were found in 40/47 (85%) of those cases. The presence of multiple respiratory pathogens in 23/40 (57.5%) cases indicated the complex origin of fatal calf pneumonia. The most important respiratory pathogens were Mannheimia-Pasteurella in 36/40 (90%) cases, followed by Arcanobacterium pyogenes in 16/40 (40%) cases, Mycoplasma bovis in 12/40 (30%) cases, and bovine respiratory syncytial virus in 4/40 (10%) cases. Histophilus somni was detected in 2/40 (5%) cases, while bovine herpesvirus-1, bovine viral diarrhoea virus and parainfluenza virus-3 were each found in 1/40 (2.5%) case. Mastadenovirus, bovine coronavirus, influenza A virus or Chlamydiaceae were not detected.

PubMed Central

Albon, Simon P.; Cancilla, Devon A.; Hubball, Harry

2006-01-01

Objectives To pilot test and evaluate a gas chromatography-mass spectrometry (GCMS) case study as a teaching and learning tool. Design A case study incorporating remote access to a GCMS instrument through the Integrated Laboratory Network (ILN) at Western Washington University was developed and implemented. Student surveys, faculty interviews, and examination score data were used to evaluate learning. Assessment While the case study did not impact final examination scores, approximately 70% of students and all faculty members felt the ILN-supported case study improved student learning about GCMS. Faculty members felt the “live” instrument access facilitated more authentic teaching. Students and faculty members felt the ILN should continue to be developed as a teaching tool. Conclusion Remote access to scientific instrumentation can be used to modify case studies to enhance student learning and teaching practice in pharmaceutical analysis. PMID:17149450

The analgetic efficacy of intraurethral instillation of anesthetic jelly in rigid cystoscopic examination for men is not clearly confirmed. This study evaluated the usefulness of intraurethral instillation of anesthetic jelly by questionnaires regarding the pain and uncomfortable feelings during and after the cystoscopic examination. A total of 62 men were enrolled in the study. Sixteen patients had not received cystoscopy previously (first cases), and 46 had prior experiences of cystoscopy more than twice (repeat cases). These patients were sequentially divided into two groups; one group (jelly-group) received intraurethral instillation of oxybuprocaine hydrochroride jelly (Benoxil jelly) prior to cystoscopic examination, and the other group (no-jelly-group) did not receive the jelly instillation. Pain during the jelly instillation to examination, and uncomfortable feelings at micturition after the examination was evaluated by questionnaires. Instillation of the jelly itself caused considerable pain, which almost similar to that of scope insertion. There was no significant difference in pain score between jelly-group and no-jelly-group during the insertion of the scope to examination. The miction pain after examination was significantly severer in the jelly-group than in the no-jelly-group in repeat cases. In addition, 75% of repeat cases felt better comfortableness when jelly was not instilled, and 96% of repeat cases did not want jelly instillation for their future examination. Intraurethral instillation of anesthetic jelly had no efficacy for reducing the pain during cystoscopy. Instillation of the jelly itself caused considerable pain, and it made pain and uncomfortable feelings after the examination worse. These results suggested that the instillation of anesthetic jelly before rigid cystoscopy in men might not be useful enough for reducing the uncomfortable feeling during the examination.

Clinical characteristics might be associated with temporomandibular disorders (TMD) because they are antecedent risk factors that increase the likelihood of a healthy person developing the condition or because they represent signs or symptoms of either subclinical or overt TMD. In this baseline case-control study of the multisite Orofacial Pain: Prospective Evaluation and Risk Assessment (OPPERA) project, 1,633 controls and 185 cases with chronic, painful TMD completed questionnaires and received clinical examinations. Odds ratios measuring association between each clinical factor and TMD were computed, with adjustment for study-site as well as age, sex, and race/ethnicity. Compared to controls, TMD cases reported more trauma, greater parafunction, more headaches and other pain disorders, more functional limitation in using the jaw, more nonpain symptoms in the facial area, more temporomandibular joint noises and jaw locking, more neural or sensory medical conditions, and worse overall medical status. They also exhibited on examination reduced jaw mobility, more joint noises, and a greater number of painful masticatory, cervical, and body muscles upon palpation. The results indicated that TMD cases differ substantially from controls across almost all variables assessed. Future analyses of follow-up data will determine whether these clinical characteristics predict increased risk for developing first-onset pain-related TMD Perspective Clinical findings from OPPERA’s baseline case-control study indicate significant differences between chronic TMD cases and controls with respect to trauma history, parafunction, other pain disorders, health status, and clinical examination data. Future analyses will examine their contribution to TMD onset. PMID:22074750

To study maternal and perinatal outcomes after physical examination-indicated cerclage in both singleton and twin pregnancies and evaluate the possible risk factors associated. Retrospective review of all women undergoing physical examination-indicated cerclage at the Hospital Vall d'Hebro, Barcelona from January 2009 to December 2012 after being diagnosed with cervical incompetence and risk of premature birth. During the study period, 60 cases of women diagnosed with cervical incompetence who were carrying live and morphologically-normal fetuses (53 singleton and 7 twin pregnancies), and who had an imminent risk of premature birth were evaluated. Mean gestational age until birth was 35 weeks in singleton and 32 weeks in twin pregnancies. Four cases (7.5%) of immature births and one case (2.0%) of neonatal death were recorded in singleton pregnancies. No cases of immature births or neonatal deaths were recorded in twin pregnancies. Diagnostic amniocentesis was performed IN all cases to rule out possible chorioamnionitis. Physical examination-indicated cerclage for cervical incompetence in women at risk for immature or preterm birth demonstrates good perinatal prognosis without increasing maternal morbidity in either singleton or twin pregnancies. The increase in gestation time in our study may also have been due to the fact that patients with subclinical chorioamnionitis were excluded by diagnostic amniocentesis.

Case conceptualization research in cognitive behavior therapy: A state of the science review.

PubMed

Easden, Michael H; Kazantzis, Nikolaos

2018-03-01

Prominent models of cognitive behavior therapy (CBT) assert that case conceptualization is crucial for tailoring interventions to adequately address the needs of the individual client. We aimed to review the research on case conceptualization in CBT. We conducted a systematic search of PsychINFO, MEDLINE, Psychology and Behavioral Science Collection, and CINAHL databases to February 2016. A total of 24 studies that met inclusion criteria were identified. It was notable that studies (a) focused on the assessment function of case conceptualization, (b) employed diverse methodologies, and, overall, (c) there remains a paucity of studies examining the in-session process of using case conceptualization or examining relations with outcome. Results from the existing studies suggest that experienced therapists can reliably construct some elements of case conceptualizations, but importance for the efficacy of case conceptualization in CBT has yet to be demonstrated. Research that involves direct observation of therapist competence in case conceptualization as a predictor of CBT outcomes is recommended as a focus for future hypothesis testing. © 2017 Wiley Periodicals, Inc.

Is work organisation associated with work status 3 months after injury? Results from a case-control study of New Zealand workers.

Lilley, Rebbecca; Derrett, Sarah; Davie, Gabrielle

2015-01-01

Little empirical examination of the relationship between work organisational factors and return to work following injury has been undertaken despite the growing recognition of examining broader multi-dimensional contexts for recovery following injury. To explore relationships between pre-injury work organisational factors and work status (working/work absent) 3-month after injury among people employed prior to injury. Cases (work absent) and controls (working), selected from a larger study of injury outcomes according to reported work status 3-month after injury, completed a postal questionnaire. Work organisational factors were compared between cases and controls using univariate and multivariable analyses. One hundred and twelve participants completed the questionnaire (44 cases; 68 controls). Of 11 work organisation factors examined, organisational size was the only explanatory variable significantly associated with work status in the multivariable model. Higher odds of work absence were found in small (< 50 employees) (OR 5.6) and large (> 500 employees) (OR 7.2) workplaces, compared with medium-sized (50-500 employees) organisations. Variations in post-injury work patterns among those working pre-injury may be partly explained by organisation size. Future research examining work status following injury should examine the influence of work organisational factors in larger studies.

Highly variable population-based prevalence rates of unilateral hearing loss after the application of common case definitions.

2010-02-01

This study shows how population-based estimates of the prevalence of unilateral hearing loss (UHL) in children aged 6 to 19 yrs can differ considerably with various applications of commonly accepted case definitions. It also examines demographic variables and risk factors related to UHL. The Third National Health and Nutrition Examination Survey, conducted from 1988 to 1994, is a national population-based, cross-sectional survey. This study examined results of audiometric testing at 0.5 to 8 kHz and demographic data from in-person examination interviews. Three definitions of UHL were used: (1) 0.5, 1, and 2 kHz > or = 15 dB pure-tone average (PTA); (2) 0.5, 1, 2, and 4 kHz > or = 15 dB PTA; and (3) 0.5, 1, and 2 kHz > or = 20 dB or PTA >25 dB at two or more frequencies above 2 kHz (3, 4, 6, and 8 kHz). Case definitions 2 and 3 are not merely subsets of case definition 1. Some overlap exists between the groups, but each case definition classifies a proportion of children who fall uniquely under that case definition. Inclusion of participants based on tympanometry results (test of middle ear function) was also examined as were demographic characteristics and risk factors associated with UHL. Overall, the weighted proportion of children with UHL using case definition 1 was 6.3% (approximately 3,213,000 children nationally); using case definition 2, it was 5.8% (approximately 2,958,000 nationally); using case definition 3, it was 3.0% (approximately 1,530,000 nationally). For all three case definitions, children who failed tympanometry were at higher risk for UHL than children who passed. For case definition 2, children from rural areas were at higher risk for UHL than were children from urban areas. This study demonstrates that different applications of well-accepted case definitions of UHL can influence population-based prevalence estimates, in this study by as much as a factor of 2. These findings highlight the importance of controlling for tympanometry status as a risk factor in such estimates. Which demographic characteristics and risk factors are significantly associated with hearing loss seem to vary depending on the case definition. These findings have implications for the interpretation of prevalence rates and risk factors in the literature on hearing loss in general. Prevalence rate estimates require careful consideration of the case definition of hearing loss, tympanometry status, and demographic characteristics.

Human exploration mission studies

NASA Technical Reports Server (NTRS)

Cataldo, Robert L.

1989-01-01

The Office of Exploration has established a process whereby all NASA field centers and other NASA Headquarters offices participate in the formulation and analysis of a wide range of mission strategies. These strategies were manifested into specific scenarios or candidate case studies. The case studies provided a systematic approach into analyzing each mission element. First, each case study must address several major themes and rationale including: national pride and international prestige, advancement of scientific knowledge, a catalyst for technology, economic benefits, space enterprise, international cooperation, and education and excellence. Second, the set of candidate case studies are formulated to encompass the technology requirement limits in the life sciences, launch capabilities, space transfer, automation, and robotics in space operations, power, and propulsion. The first set of reference case studies identify three major strategies: human expeditions, science outposts, and evolutionary expansion. During the past year, four case studies were examined to explore these strategies. The expeditionary missions include the Human Expedition to Phobos and Human Expedition to Mars case studies. The Lunar Observatory and Lunar Outpost to Early Mars Evolution case studies examined the later two strategies. This set of case studies established the framework to perform detailed mission analysis and system engineering to define a host of concepts and requirements for various space systems and advanced technologies. The details of each mission are described and, specifically, the results affecting the advanced technologies required to accomplish each mission scenario are presented.

To observe the effect of skill lab training on academic performance of final year medical students in terms of marks obtained in long case, short case, objective structured clinical examination and viva. The cross-sectional comparative study was conducted at Army Medical College, Rawalpindi from February to April 2015. Two batches of final year MBBS were recruited for the study. Batch 1 received conventional training, and Batch 2 received skill lab training. The performance of students was assessed by comparing the marks obtained in long case, short case, objective structured clinical examination and viva. Data was analysed using SPSS 23. Of the 335 subjects, 168(50.1%) were male and 167(49.9%) were female students with a mean age of 21.79±1.02 years. Batch 1 had 151(45%) students and Batch 2 had 184(55%). Batch 2 got significantly higher marks in long case, short case and objective structured clinical examination (p<0.05 each). Viva result was not found to be related to training (p>0.05). Acquisition of clinical skills significantly improved when medial students were trained in skill laboratories.

The number of very low birth weight (VLBW) births is increasing worldwide. Despite better care in recent years, they have a high incidence of delayed growth and development. There are no previous studies regarding the growth and development of these infants at Queen Sirikit National Institute of Child Health (QSNICH). To study growth and developmental outcome of VLBW infants, aged 18-24 months who were discharged from QSNICH. VLBW infants who were discharged from QSNICH during the year 2007 were recruited in the study. Patients with chromosomal abnormalities, major congenital anomalies, definite congenital infections and positive maternal anti-HIV tests were excluded. At the corrected age of 18-24 months, the parents were called upon to bring their infants for complete physical examination and developmental evaluation on 2 occasions, two months apart. There were 111 cases of VLBW infants who were discharged from QSNICH during the year 2007. Fifty-four patients were eligible for the present study. Thirty cases (55.56%) were contacted for the first examination. During this examination, there were 3 cases (10%) with low head circumference, 1 case (3.33%) with poor weight gain, 5 cases (16.67%) with visual defect, 1 case (3.33%) with moderately severe hearing loss, 1 case (3.33%) with cerebral palsy and 7 cases (23.33%) with delayed development. Twenty-one cases could be recalled for a second evaluation. Two of the 5 cases had delayed language development. There were no cases with hydrocephalous, blindness or profound hearing loss. VLBW infants at QSNICH had much better survival during recent years. Most of these survivors had normal growth and development. Those with delayed growth and development need aggressive intervention and long-term follow-up for enhancement of quality of their lives.

The aim of the work was to make a systemic study of the variability of the human musculus peroneus tertius during the foetal period. Examination was made of 193 foetuses of ages ranging from 84 to 256 days after conception. The results obtained indicated that the musculus peroneus tertius was present in 83.16% of the human foetuses studied and that its intrauterine development was progressive and almost proportional. Previous studies have not revealed dimorphic or bilateral differences with respect to any of the features examined. On the basis of the examinations and bibliographical data a uniform typology of the musculus peroneus tertius variants was created and three final types were distinguished: the pithecogenic (44% cases), eugenic (34% cases) and progenic (22% cases).

Introduction The major cause of death in the burn patients includes multiple organ failure and infection but, sometimes the exact cause of death in many fatally burned patients is difficult to detect. Many times in medico-legal post-mortem examinations in cases of burns, histopathological examination of organs is requested. Aim The aim was to study various histopathological changes in kidneys in the post-mortem cases of burns, by using routine Haematoxylin and Eosin stain (H&E stain), special Periodic and Schiff’s Stain (PAS) stain, to study the role of acridine orange fluorescence study, to explore the forensic utility of this microscopic study and to find out the relationship between duration of survival and histopathological changes observed. Materials and Methods An experimental longitudinal prospective study from October 2010 to September 2012. Total 32 cases of death due to burns were autopsied at mortuary, the Department of Forensic Medicine and Toxicology in our hospital. Bilateral kidneys were removed and preserved in 10% formalin solution. These were forwarded to Department of Pathology for histopathological examination. Routine microscopic examination by H&E stain as well as PAS stain and fluorescence study by acridine orange stain were done in all cases. Results It was observed that in 21 (65.63%) cases gross findings in kidneys were normal, in 06 (18.75%) were grossly pale and in 05 (15.62%) heavy & congested. Sections taken from kidneys and studied by H&E stain showed overlapping histopathological changes in all cases. In 26 (81.25%) cases, changes of Acute Tubular Necrosis (ATN) while in remaining 06 (18.75%), changes of cloudy swelling were observed. The sections stained by acridine orange and observed under fluorescent microscope were lightly positive in 15 (46.88%), brightly positive in 08 (25.00%) whereas, negative in 09 (28.12%). Conclusion Microscopy by various methods helps in getting specific lesions in kidney due to burns. However, it does not add any new tool to resolve any forensic issues of burns. Therefore, microscopy (including florescent), if done would be redundant. PMID:27190809

Implementation of case studies in undergraduate didactic nursing courses: a qualitative study.

PubMed

Dutra, Danette K

2013-07-04

The implementation of unfolding scenario-based case studies in the didactic classroom is associated with learner-centered education. The utilization of learner-centered pedagogies, such as case studies, removes the focus from the instructor and instead places it on the student. Learner-centered pedagogies are believed to improve students' levels of cognition. The purpose of this study was to examine how nurse educators are implementing the pedagogies of case studies in their undergraduate didactic courses. The goal was to examine, document, report, and, ultimately, implement the strategies. Purposeful sampling was utilized in this qualitative, multisite-designed study. For each of the four participants, three separate site visits were completed. Observations and post-observational interviews took place at each site visit. Transcribed data from interviews, observations, and course documents were imported into the computer program Nvivo8. Repetitive comparative analysis was utilized to complete the data coding process. The guiding research question of this study sought to investigate the implementation strategies of case studies in didactic nursing courses. The implementation of case studies by the participants reflected two primary patterns: Formal Implementation (FI) and Informal Implementation (II) of case studies. The FI of case studies was further divided into two subcategories: Formal Implementation of case studies used Inside the Classroom setting (FIIC) and Formal Implementation of cases studies used Outside of the Classroom (FIOC). Results of this investigation have led to an increased understanding of implementation strategies of unfolding scenario-based case studies in undergraduate nursing didactic courses. Data collected were rich in the description of specific methodologies for utilization of case studies and may serve as a resource for faculty in development of creative strategies to enhance the didactic classroom experience.

Sporotrichosis is a common subcutaneous mycosis caused by an infection with dimorphic fungus Sporothrix schenckii. We present a series of patients with eyelid sporotrichosis and study the clinical and histopathological presentation, microbiology, treatment options, and outcome. A retrospective case-series study of patients with a clinical diagnosis of eyelid sporotrichosis. Records were examined to obtain information regarding patient demographics, presenting symptoms and signs, histopathological examination, microbiology, management, and outcomes. Ten patients (4 men, 6 women; mean age 46.5 years, range 3-81 years) were included. Based on their clinical manifestations, eyelid sporotrichosis was classified into 3 major forms: (i) fixed cutaneous (6/10 cases), (ii) lymphocutaneous (3/10 cases), and (iii) eyelid abscess (1/10 cases). All the cases were treated with a terbinafine 12-week regimen. Nodules, papules, and abscesses regressed after treatment. No recurrence was discovered after a 12-week follow-up. Eyelid sporotrichosis has typical features of clinical manifestations. Histopathological examination and tissue culture are helpful for diagnosis. Confirmed cases normally require long-term systematic treatment with antifungal agents, but surgical removal is normally unnecessary. Copyright © 2016 Canadian Ophthalmological Society.

2012-01-01

The aim of this study is to evaluate the role of functional imaging for forensic purposes. We reviewed a few outpatient cases that were sent to our department for examination after traumatic events and one case with neuropsychic disturbances. Functional imaging showed signs of traumatic lesions in the skeletal system, of brain metabolism and of renal failure. Functional disturbances following traumatic events are in some cases more important than morphological abnormalities. Targeted scintigraphic examinations could be applied for visualisation of traumatic lesions or evaluation of functional disturbances caused by traumatic events. These examinations can be used as evidence in the courtroom.

Protease inhibitors: changing the way AIDS case management does business.

Merithew, M A; Davis-Satterla, L

2000-09-01

The purpose of the qualitative evaluation study discussed in this article was to examine the AIDS case management model under which five nonprofit AIDS service organizations (ASOs) in Midcity were operating. The study was organized around 40 qualitative interviews with executive directors, directors, and case managers. The finding was that AIDS case management is evolving to accommodate the changing environmental/contextual conditions that have resulted from combination drug therapies (protease inhibitors) introduced in 1996. The agencies are responding to the changes individually rather than as a network, and responses vary among the agencies. Institutional theory, an examination of the interconnectedness of clients, the ASOs, and their environmental context guided the analysis of the findings.

Forensic mental health evaluations of military personnel with traumatic life event, in a university hospital in Ankara, Turkey.

Balandiz, Huseyin; Bolu, Abdullah

2017-10-01

The definition of psychological trauma has been rephrased with the DSM-5. From now on, witnessing someone else's traumatic event is also accepted as a traumatic life event. Therefore, the psychiatric examination of forensic cases gains importance for not overlooking a psychiatric trauma. This research aims to discuss the psychiatric examinations of military personnel who had a traumatic life event and to reveal psychiatric states of soldiers after trauma. The forensic reports prepared at Gulhane Military Medical Academy (GMMA), Forensic Medicine polyclinic between January 1, 2011 and November 30, 2014 were examined, and among them the cases sent to GMMA Psychiatry polyclinic for psychiatric examination were analyzed retrospectively. There were a total of 2408 cases who applied for the arrangement of a judicial report and 167 of them required a psychological examination. Among 167 cases, 165 were male and 2 were female, and the mean age was 25.6 years. Anxiety disorder (53.9%) was the most common diagnosis as a result of the psychiatric examination, following posttraumatic stress disorder (PTSD) (18.6%), and 3.6% had no psychopathology. It was determined that injuries caused by firearms (38.3%) and explosive materials (26.3%) had caused psychological trauma the most. On the other hand, 11 (6.6%) cases were determined to have undergone a psychological trauma on account of being a witness to their friends' injuries during the conflict without experiencing any physical injury. There were not any statistically significant relationships between the severity of physical injury and being PTSD or anxiety disorder. Development of PTSD risk is directly correlated with the nature of trauma. The trauma types of the cases in our study were in the high-risk group because of the military population. Our study is of importance in terms of putting forward the psychiatric disorders seen in the military population with traumatic life history associated with war (combat-related). In this research, 26.1% of the cases followed up due to combat-related trauma were diagnosed with PTSD. Interestingly, this ratio was lower than the studies that have larger case numbers. There is still the need to conduct studies that will involve larger participants. Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Walsh, Wendy A; Cross, Theodore P; Jones, Lisa M; Simone, Monique; Kolko, David J

2007-10-01

This study examines the impact of Children's Advocacy Centers (CAC) and other factors, such as the child's age, alleged penetration, and injury on the use of forensic medical examinations as part of the response to reported child sexual abuse. This analysis is part of a quasi-experimental study, the Multi-Site Evaluation of Children's Advocacy Centers, which evaluated four CACs relative to within-state non-CAC comparison communities. Case abstractors collected data on forensic medical exams in 1,220 child sexual abuse cases through review of case records. Suspected sexual abuse victims at CACs were two times more likely to have forensic medical examinations than those seen at comparison communities, controlling for other variables. Girls, children with reported penetration, victims who were physically injured while being abused, White victims, and younger children were more likely to have exams, controlling for other variables. Non-penetration cases at CACs were four times more likely to receive exams as compared to those in comparison communities. About half of exams were conducted the same day as the reported abuse in both CAC and comparison communities. The majority of caregivers were very satisfied with the medical professional. Receipt of a medical exam was not associated with offenders being charged. Results of this study suggest that CACs are an effective tool for furthering access to forensic medical examinations for child sexual abuse victims.

Head circumference is a valuable index of brain growth and its disturbances can indicate different disorders of nervous system. Abnormal increased head circumference (macrocephaly) is common and observed in about 2% of infants. In this study, the causes and clinical types of abnormal increase in infants' head circumference were investigated in Kashan, Iran. This cross-sectional study was performed on 90 infants less than 2 years of age with abnormal increase in head circumference in Kashan, during 2009- 2011. The data were collected by history taking, physical examination, growth chart, and imaging. 65 (72%) cases out of 90 infants were male and 25 ( 28%) cases were female. Fifty-three (58.8%) cases had familial megalencephaly, 30 (33.4%) had hydrocephalus, and other causes were observed in 7 (7.8%) cases. Eighty-three percent of Infants with familial megalencephaly and 50% with hydrocephalus had normal fontanels. In 90.6% of cases with familial megalencephaly, family history for large head was positive. Motor development was normal in 100% of cases with familial megalencephaly and 76.7% of hydrocephalic infants. Familial megalencephaly was the most common cause of macrocephaly in the studied infants, and most of them had normal physical examination and development, so, parental head circumferences should be considered in the interpretation of infant's head circumference and in cases of abnormal physical examination or development, other diagnostic modalities, including brain imaging should be done.

Shared written case formulations and weight change in outpatient therapy for anorexia nervosa: a naturalistic single case series.

PubMed

Gladwin, Alice M; Evangeli, Michael

2013-01-01

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

Paediatric lung sound recordings can be systematically assessed, but methodological feasibility and validity is unknown, especially from developing countries. We examined the performance of acoustically interpreting recorded paediatric lung sounds and compared sound characteristics between cases and controls. Pneumonia Etiology Research for Child Health staff in six African and Asian sites recorded lung sounds with a digital stethoscope in cases and controls. Cases aged 1-59 months had WHO severe or very severe pneumonia; age-matched community controls did not. A listening panel assigned examination results of normal, crackle, wheeze, crackle and wheeze or uninterpretable, with adjudication of discordant interpretations. Classifications were recategorised into any crackle, any wheeze or abnormal (any crackle or wheeze) and primary listener agreement (first two listeners) was analysed among interpretable examinations using the prevalence-adjusted, bias-adjusted kappa (PABAK). We examined predictors of disagreement with logistic regression and compared case and control lung sounds with descriptive statistics. Primary listeners considered 89.5% of 792 case and 92.4% of 301 control recordings interpretable. Among interpretable recordings, listeners agreed on the presence or absence of any abnormality in 74.9% (PABAK 0.50) of cases and 69.8% (PABAK 0.40) of controls, presence/absence of crackles in 70.6% (PABAK 0.41) of cases and 82.4% (PABAK 0.65) of controls and presence/absence of wheeze in 72.6% (PABAK 0.45) of cases and 73.8% (PABAK 0.48) of controls. Controls, tachypnoea, >3 uninterpretable chest positions, crying, upper airway noises and study site predicted listener disagreement. Among all interpretable examinations, 38.0% of cases and 84.9% of controls were normal (p<0.0001); wheezing was the most common sound (49.9%) in cases. Listening panel and case-control data suggests our methodology is feasible, likely valid and that small airway inflammation is common in WHO pneumonia. Digital auscultation may be an important future pneumonia diagnostic in developing countries.

Jain, Garima; Shetty, Pushparaja

2015-01-01

Fine-needle aspiration cytology (FNAC) is not a definitive preoperative diagnostic procedure done for all cases of odontogenic cysts. This is because of the inconsistent results obtained with it. This study was done to optimize FNAC findings and help in preoperative characterization of odontogenic cysts. Cystic fluid was collected and centrifuged from 50 odontogenic cysts that were planned for excision. Three smears were prepared from the cell sediment obtained after centrifugation and stained. The stained sections were examined for presence and type of epithelial cells, to formulate a preopererative diagnosis. Epithelial cells were detected in 46% cases in smear 1, 48% cases in smear 2, and 52% cases in smear 3. When all three smears from one case were studied, 86% cases showed epithelial cells for evaluation. Cystic aspirate should be centrifuged and the entire cell sediment should be examined by making multiple smears for evaluation of cystic epithelial lining cells.

This paper discusses a case study that examined the influence of cultural, organizational and automation capability upon human trust in, and reliance on, automation. In particular, this paper focuses on the design and application of an extended case study methodology, and on the foundational lessons revealed by it. Experimental test pilots involved in the research and development of the US Air Force's newly developed Automatic Ground Collision Avoidance System served as the context for this examination. An eclectic, multi-pronged approach was designed to conduct this case study, and proved effective in addressing the challenges associated with the case's politically sensitive and military environment. Key results indicate that the system design was in alignment with pilot culture and organizational mission, indicating the potential for appropriate trust development in operational pilots. These include the low-vulnerability/ high risk nature of the pilot profession, automation transparency and suspicion, system reputation, and the setup of and communications among organizations involved in the system development.

Coming to terms: a case study of hospice collaboration challenges.

PubMed

Pietroburgo, Julie; Bush, Richard

Recent research has focused on the growing phenomenon of mergers, collaborations, and alliances among nonprofit organizations and what makes such arrangements work. Examination of failed collaborative efforts is perhaps just as instructive. This case study examines recent attempts at collaboration between 2 nonprofit hospice organizations. The study finds that despite compelling reasons for and significant commonalities on which to base collaboration, the organizations were initially unable to forge any ongoing and substantive collaborative arrangement because of insurmountable cultural factors and past history. Furthermore, without imminent external pressures to collaborate, these organizations had insufficient motivation to attempt to move beyond their differences. The case also reviews the changed circumstances and factors that later facilitated partnering attempts.

Performance changes in a binary environment when using additional information is affected only when changes in recommendations are made due to the additional information in question. In a recent study, we have shown that, contrary to general expectation, introducing prior examinations improved recall rates, but not sensitivity. In this study, we assessed cancer detection differences when prior examinations and/or digital breast tomosynthesis (DBT) were made available to the radiologist. We identified a subset of 21 cancer cases with differences in the number of radiologists who recalled these cases after reviewing either a prior examination or DBT. For the cases with differences in recommendations after viewing either priors or DBT, separately, we evaluated the total number of readers that changed their recommendations, regardless of the specific radiologist in question. Confidence intervals for the number of readers and a test for the hypothesis of no difference was performed using the non-parameteric bootstrap approach addressing both case and reader-related sources of variability by resampling cases and readers. With the addition of priors, there were 14 cancer cases (out of 15) where the number of "recalling radiologists" decreased. With the addition of DBT, the number of "recalling radiologists" decreased in only five cases (out of 15) while increasing in the remaining 9 cases. Unlike most new approaches to breast imaging DBT seems to improve both recall rates and cancer detection rates. Changes in recommendations were noted by all radiologists for all cancers by type, size, and breast density.

The purpose of this study was to improve the quality of items on the Korean Nursing Licensing Examination by developing and evaluating case-based items that reflect integrated nursing knowledge. We conducted a cross-sectional observational study to develop new case-based items. The methods for developing test items included expert workshops, brainstorming, and verification of content validity. After a mock examination of undergraduate nursing students using the newly developed case-based items, we evaluated the appropriateness of the items through classical test theory and item response theory. A total of 50 case-based items were developed for the mock examination, and content validity was evaluated. The question items integrated 34 discrete elements of integrated nursing knowledge. The mock examination was taken by 741 baccalaureate students in their fourth year of study at 13 universities. Their average score on the mock examination was 57.4, and the examination showed a reliability of 0.40. According to classical test theory, the average level of item difficulty of the items was 57.4% (80%-100% for 12 items; 60%-80% for 13 items; and less than 60% for 25 items). The mean discrimination index was 0.19, and was above 0.30 for 11 items and 0.20 to 0.29 for 15 items. According to item response theory, the item discrimination parameter (in the logistic model) was none for 10 items (0.00), very low for 20 items (0.01 to 0.34), low for 12 items (0.35 to 0.64), moderate for 6 items (0.65 to 1.34), high for 1 item (1.35 to 1.69), and very high for 1 item (above 1.70). The item difficulty was very easy for 24 items (below -2.0), easy for 8 items (-2.0 to -0.5), medium for 6 items (-0.5 to 0.5), hard for 3 items (0.5 to 2.0), and very hard for 9 items (2.0 or above). The goodness-of-fit test in terms of the 2-parameter item response model between the range of 2.0 to 0.5 revealed that 12 items had an ideal correct answer rate. We surmised that the low reliability of the mock examination was influenced by the timing of the test for the examinees and the inappropriate difficulty of the items. Our study suggested a methodology for the development of future case-based items for the Korean Nursing Licensing Examination.

2013-01-01

Background Tuberculosis (TB) is an important public health problem in the Northwest Territories (NWT), particularly among Canadian Aboriginal people. Objective To analyse the transmission patterns of tuberculosis among the population living in the NWT, a territorial jurisdiction located within Northern Canada. Methods This population-based retrospective study examined the DNA fingerprints of all laboratory confirmed cases of TB in the NWT, Canada, between 1990 and 2009. An isolate of each lab-confirmed case had genotyping done using IS6110 Restriction Fragment Length Polymorphism. DNA patterns were assigned to each DNA fingerprint, and indistinguishable fingerprints patterns were assigned a cluster. Social network analysis (SNA) was used to examine direct linkages among cases determined through conventional contact tracing (CCT), their DNA fingerprint and home community. Results Of the 225 lab-confirmed cases identified, the study was limited to 195 subjects due to DNA fingerprinting data availability. The mean age of the cases was 43.8 years (±22.6) and 120 (61.5%) males. The Dene (First Nations) encompassed 120 of the cases (87.7%), 8 cases (4.1%) were Inuit, 2 cases (1.0%) were Metis, 7 cases (3.6%) were Immigrants and 1 case had unknown ethnicity. One hundred and eighty six (95.4%) subjects were clustered, resulting in 8 clusters. Trend analysis showed significant relationships between with risk factors for unemployment (p=0.020), geographic location (p≤0.001) and homelessness (p≤0.001). Other significant risk factors included excessive alcohol consumption, prior infection with Mycobacterium tuberculosis and prior contact with a case of TB. Conclusions This study demonstrates how DNA fingerprinting and SNA can be additional epidemiological tools, along with CCT method, to determine transmission patterns of TB. PMID:23671837

Because benign and malignant cervical and ovarian masses occur with different percentages in different age groups, the importance of primary diagnosis and selection of a suitable surgical procedure is underlined. Diagnosis of pelvic masses is carried out using ultrasound, physical examination, CT scan and MRI. The objective of this study is to evaluate the diagnostic value of CT scan in pelvic masses in comparison with physical examination-ultrasound based on pathology of the lesion in patients undergoing laparotomic surgery. This analytic-descriptive study focused on age, sonographic findings, physical examinations, CT scan and pathological findings in 139 patients with pelvic mass, gathered with questionnaires and statistically analayzed using the SPSS software programme. Of 139 patients with pelvic mass (patients aged from 17 to 75 years old), 62 (44%) cases were diagnosed as benign and 77 (55.4%) as malignant; among them malignant tratoma serocyst adenocarsinoma with 33 (23.7%) cases and benign myoma with 21 (15.2%) cases comprised the most frequent cases. The sensitivity and specificity of sonography-physical examination were 51.9% and 87.9% respectively and the sensitivity and specificity of CT scan images were 79.2% and 91.6% respectively. It was shown that CT scan images were more consistant with pathological findings in predicting appropriate surgical procedures than do sonography-physical examinations. The sensitivity of CT scan is far higher than that of sonography-physical examination in the diagnosis of pelvic mass malignancy.

Examining the Use of a Visual Analytics System for Sensemaking Tasks: Case Studies with Domain Experts.

PubMed

Kang, Youn-Ah; Stasko, J

2012-12-01

While the formal evaluation of systems in visual analytics is still relatively uncommon, particularly rare are case studies of prolonged system use by domain analysts working with their own data. Conducting case studies can be challenging, but it can be a particularly effective way to examine whether visual analytics systems are truly helping expert users to accomplish their goals. We studied the use of a visual analytics system for sensemaking tasks on documents by six analysts from a variety of domains. We describe their application of the system along with the benefits, issues, and problems that we uncovered. Findings from the studies identify features that visual analytics systems should emphasize as well as missing capabilities that should be addressed. These findings inform design implications for future systems.

Relationship between clinical signs and postmortem test status in cattle experimentally infected with the bovine spongiform encephalopathy agent

PubMed Central

2010-01-01

Background Various clinical protocols have been developed to aid in the clinical diagnosis of classical bovine spongiform encephalopathy (BSE), which is confirmed by postmortem examinations based on vacuolation and accumulation of disease-associated prion protein (PrPd) in the brain. The present study investigated the occurrence and progression of sixty selected clinical signs and behaviour combinations in 513 experimentally exposed cattle subsequently categorised postmortem as confirmed or unconfirmed BSE cases. Appropriate undosed or saline inoculated controls were examined similarly and the data analysed to explore the possible occurrence of BSE-specific clinical expression in animals unconfirmed by postmortem examinations. Results Based on the display of selected behavioural, sensory and locomotor changes, 20 (67%) orally dosed and 17 (77%) intracerebrally inoculated pathologically confirmed BSE cases and 21 (13%) orally dosed and 18 (6%) intracerebrally inoculated but unconfirmed cases were considered clinical BSE suspects. None of 103 controls showed significant signs and were all negative on diagnostic postmortem examinations. Signs indicative of BSE suspects, particularly over-reactivity and ataxia, were more frequently displayed in confirmed cases with vacuolar changes in the brain. The display of several BSE-associated signs over time, including repeated startle responses and nervousness, was significantly more frequent in confirmed BSE cases compared to controls, but these two signs were also significantly more frequent in orally dosed cattle unconfirmed by postmortem examinations. Conclusions The findings confirm that in experimentally infected cattle clinical abnormalities indicative of BSE are accompanied by vacuolar changes and PrPd accumulation in the brainstem. The presence of more frequently expressed signs in cases with vacuolar changes is consistent with this pathology representing a more advanced stage of disease. That BSE-like signs or sign combinations occur in inoculated animals that were not confirmed as BSE cases by postmortem examinations requires further study to investigate the potential causal relationship with prion disease.

Homicide committed by psychiatric patients: Psychiatrists' liability in Italian law cases.

PubMed

Terranova, Claudio; Rocca, Gabriele

2016-01-01

Interest in psychiatrists' professional liability in Italy has increased in recent years because of the number of medical malpractice claims. Professional liability for failure to prevent violent behaviour by psychiatric patients is particularly debated. This study describes three Italian cases in which health professionals - physicians and nurses - were found guilty of manslaughter for murders committed by psychiatric patients. Examination of the cases focuses on claims of malpractice, patients' characteristics, the circumstances of the homicide and the reasons for the court's judgment. In particular, the predictability of violent behaviour and the concept of causal links are examined in detail. The cases provide an opportunity for a study of comparative jurisprudence. The topics discussed are relevant not only to practicing psychiatrists but also to experts assessing medical liability in cases of criminal acts committed by psychiatric patients. © The Author(s) 2015.

2014-02-01

Complications during the perinatal period have been associated with neurodevelopmental disorders like schizophrenia and autism. However, similar studies on bipolar disorder (BPD) have been limited and the findings are inconsistent. The aim of this study was to examine the association between perinatal risk factors and BPD. This nested case-control study, based on the Finnish Prenatal Study of Bipolar Disorders (FIPS-B), identified 724 cases and 1419 matched controls from population based registers. Conditional logistic regression was used to examine the associations between perinatal factors and BPD adjusting for potential confounding due to maternal age, psychiatric history and educational level, place of birth, number of previous births and maternal smoking during pregnancy. Children delivered by planned cesarean section had a 2.5-fold increased risk of BPD (95% CI: 1.32-4.78, P<0.01). No association was seen between other examined perinatal risk factors and BPD. The limitations of this study include: the restriction in the sample to treated cases of BPD in the population, and usage of hospital based clinical diagnosis for case ascertainment. In addition, in spite of the large sample size, there was low power to detect associations for certain exposures including the lowest birth weight category and pre-term birth. Birth by planned cesarean section was associated with risk of BPD, but most other perinatal risk factors examined in this study were not associated with BPD. Larger studies with greater statistical power to detect less common exposures and studies utilizing prospective biomarker-based exposures are necessary in the future. © 2013 Published by Elsevier B.V.

The aim of the study was to investigate the potential role of chest tomosynthesis (CTS) at a tertiary referral centre by exploring to what extent CTS could substitute chest radiography (CXR) and computed tomography (CT). The study comprised 1433 CXR, 523 CT and 216 CTS examinations performed 5 years after the introduction of CTS. For each examination, it was decided if CTS would have been appropriate instead of CXR (CXR cases), if CTS could have replaced the performed CT (CT cases) or if CT would have been performed had CTS not been available (CTS cases). It was judged that (a) CTS had been appropriate in 15 % of the CXR examinations, (b) CTS could have replaced additionally 7 % of the CT examinations and (c) CT would have been carried out in 63 % of the performed CTS examinations, had CTS not been available. In conclusion, the potential role for CTS to substitute other modalities during office hours at a tertiary referral centre may be in the order of 20 and 25 % of performed CXR and chest CT, respectively.

The practice of integrating western and traditional indigenous medicine is fast becoming an accepted and more widely used approach in health care systems throughout the world. However, debates about intercultural health approaches have raised significant concerns. This paper reports findings of five case studies on intercultural health in Chile, Colombia, Ecuador, Guatemala, and Suriname. It presents summary information on each case study, comparatively analyzes the initiatives following four main analytical themes, and examines the case studies against a series of the best practice criteria.

A total of 1,205 primary school children were examined for cystic echinococcosis in five villages of Manisa, Turkey, to evaluate the efficacy of diagnostic methods of this infection in community-based screening surveys. Six hundred and thirty children from three villages, examined by a portable ultrasound scanner, chest microfilm and serological methods (ELISA, indirect hemagglutination) in our previous study, were designated as Study Group 1; and 575 children, from two adjacent villages, examined by ultrasonography alone in the present study, were designated as Study Group 2. In Study Group 1, hepatic cystic echinococcosis was detected in two cases (0.3%) by ultrasonography, while 43 (8.9%) and 49 (10.1%) cases were found to be positive for cystic echinococcosis by ELISA and indirect hemagglutination, respectively. Three of 575 children (0.5%) were diagnosed with cystic echinococcosis (two hepatic and one renal involvement) by ultrasonography alone in Study Group 2; and lung lesions were later detected in both cases with liver involvement by chest radiography. Our results suggested that serological tests may be beneficial in suspected cases for confirmation and differential diagnosis, but have some drawbacks, such as discrepancy in results and high false seropositivity rates. Chest microfilm is not easy in field studies and exposure to X-ray is undesirable. As a reliable, simple, inexpensive and rapid technique, ultrasonography alone is recommended to be used in community-based screening surveys for cystic echinococcosis with confirmatory tests for suspected cases found during the screening program.

To study the evolution of subretinal precipitates coexistent with optic disc pit (ODP) maculopathy from their appearance at baseline examination until their absorption after successful treatment. Participants in this retrospective, multicenter study were 42 patients with ODP maculopathy, in whom complete ocular examination was performed, including visual acuity (VA) measurement, slit-lamp examination, color or red-free fundus photography, and optical coherence tomography at baseline after surgical treatment. Out of 42 cases, 17 (40.5%) cases of ODP maculopathy, which were examined between 2002 and 2015, were found to have subretinal precipitates associated with multilayer fluid accumulation at baseline. Precipitates were located at the outer part of the photoreceptor layer and remained for 3-6 months after successful treatment and absorption of subretinal fluid. The mean VA was 0.99 ± 0.21 logMAR at baseline and improved to 0.54 ± 0.25 logMAR at the final examination. Macular precipitates in association with signs of disease chronicity, such as multilayer fluid accumulation, became evident at baseline examination. Precipitates' disappearance in 15 out of 17 cases coincided with the absorption of subretinal fluid. The relative low VA at baseline probably could be attributed to the chronicity of the disease.

Various characteristics of the medico-legal scene in Dubai are described, along with an overview of all cases examined over a period of 6 years. During the period of study, a total of 17,683 cases were examined in the Department of Forensic Medicine of Dubai Police General Headquarters. This constituted a yearly average of (2947.16). The average annual increment was 11.13%, the percentage of increase between 2002 and 2007 being 68.96%. Of these 10,165 (57.48%) were clinical cases of injuries, 5404 (30.56%) postmortem examinations, 1525 (8.62%) clinical cases of sexual crimes, 409 (2.3%) age estimations, 58 (0.32%) medical responsibility, 20 (0.11%) criminal abortion, 61 (0.34%) civil actions and 38 (0.21%) miscellaneous cases. Of postmortem examinations, 4846 (89.7%) of them were males and 558 (10.3%) females. The age ranged from (0-90) years, with a mean age of 40.5 years. The peak incidence was in the age group (20-50) years, where the extremes of age were least represented (Fig. 1). Only in 361 cases (6.68% of the grand total) the deceased was a local citizen. Autopsies amounted to 394 cases, which constituted 7.29% of the total deaths examined. The four manners of death in descending order of frequency were natural 3003 (55.57%), accidental 1727 (32%), suicidal 498 (9.2%), homicidal 164 (3%). The manner was undetermined in 12 (0.22%) of the cases over the 6 year period.

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) represent a group of tumors, having their origin in cells of diffuse endocrine system, with particular clinical course, diagnosis and treatment. In our study, were included 68 patients with neuroendocrine digestive tumors admitted, diagnosed and treated in Fundeni Clinical Institute, Bucharest, in the last ten years--2000-2010 (retrospective study). Thirty-three (49%) patients were males, 35 (51%) females, and the main age was 58.9 years. In 62 (90.3%) cases was possible to find the primary tumor. The examined tumors had different localizations: pancreas--32 (47.04%) cases (head--17 (24.99%) cases, and body and tail--15 (22.05%) cases), stomach--7 (10.29%) cases, small intestine--7 (10.29%) cases, 6 (8.82%) cases--unknown primary site (diagnosis was established on metastases), right colon--6 (8.82%) cases, liver--6 (8.82%) cases, rectum--2 (2.94%) cases, and retroperitoneum--2 (2.94%) cases. Microscopic examination revealed 59 (86.8%) malignant tumors and 9 (13.2%) benign tumors. Using WHO 2000 Classification, 28 cases of malignant tumors were well-differentiated neuroendocrine carcinomas, and 31 cases were poor differentiated neuroendocrine carcinomas. From malignant cases, 25 (42.3%) have distant metastases and 15 (25.9%) lymph node metastases. Cases of gastroenteropancreatic neuroendocrine tumors included in our study had clinical and histopathological features in correspondence with data from literature--slight predominance in women, predominance in 5th and 6th decades of life, the most frequent localizations were at pancreatic level--both head and body and tail, but the rarest were in colon and retroperitoneum. Most of the cases studied, were malignant tumors, from these more than a half were poor differentiated, and a quarter of them having lymph node or distant metastases.

To explore the clinical strategies for the screening of newborn eye diseases and obtain information concerning the incidence of newborn ocular diseases. Newborns in a baby-friendly nursery were evaluated for mass screening of eye diseases 2 to 7 days after birth (including reaction to light stimulation, external ocular examination and test for pupil red reflex) and those with abnormalities were subjected to diagnostic examination (external ocular examination with a hand-held slit-lamp, pupil red reflex and mydriatic examination). Newborns in neonatal intensive care unit (NICU) were subjected to screening 5 to 14 days after birth and then, together with those with high risk factors, received a comprehensive examination for screening and diagnostic purposes. The suspected cases were referred to department of ophthalmology for definite diagnosis. Among the 15,398 (91.65%) newborns who were enrolled the screening program, 12 different eye diseases (involving 1266 cases) were detected, with a prevalence of 8.22%. Of these eye diseases, 7 were congenital ocular diseases, involving 809 cases (5. 254%) and including congenital ptosis in 2 cases (0.013%), congenital corneal opacity in 6 cases (0.039%), persistent pupillary membrane in 724 cases (4.702%), congenital cataract in 15 cases (0.097%), persistent hyaloid artery in 54 cases (0.351%), obstruction of nasolacrimal duct in 7 cases (0.046%) and lacrimal gland prolapse in 1 cases (0.007%). Five different diseases (457 cases, 2. 968%) detected were acquired in nature, including neonatal conjunctivitis in 391 case (2.539%), vitreous hemorrhage in 6 cases (0.039%), retinal hemorrhage in 34 cases (0.221%), and neonatal dacryocystitis in 23 cases (0.149%). Of 27 premature babies with body weight lower than 1500 g, 3 had retinopathy of prematurity (ROP, 6 eyes involved). Early intervention is of great importance for the prevention and treatment of neonatal ocular diseases. The screening of newborn ocular diseases is not only feasible but also effective in the monitoring and control of the eye diseases in neonates.

In the course of criticality code validation, outlier cases are frequently encountered. Historically, the causes of these unexpected results could be diagnosed only through comparison with other similar cases or through the known presence of a unique component of the critical experiment. The sensitivity and uncertainty (S/U) analysis tools available in the SCALE 6.1 code system provide a much broader range of options to examine underlying causes of outlier cases. This paper presents some case studies performed as a part of the recent validation of the KENO codes in SCALE 6.1 using S/U tools to examine potential causes of biases.

This study examined the role of reflection on personal cases for making ethical decisions with regard to new ethical problems. Participants assumed the position of a business manager in a hypothetical organization and solved ethical problems that might be encountered. Prior to making a decision for the business problems, participants reflected on a relevant ethical experience. The findings revealed that application of material garnered from reflection on a personal experience was associated with decisions of higher ethicality. However, whether the case was viewed as positive or negative, and whether the outcomes, process, or outcomes and processes embedded in the experience were examined, influenced the application of case material to the new problem. As expected, examining positive experiences and the processes involved in those positive experiences resulted in greater application of case material to new problems. Future directions and implications for understanding ethical decision-making are discussed. PMID:26257506

In assessment meetings concerning care services for people with dementia, Swedish case managers face a dilemma. On the one hand, according to the law, the right to self-determination of every adult citizen must be respected, but on the other hand cognitive disabilities make it difficult to fulfill obligations of being a full-fledged citizen. In this article, we examine 15 assessment meetings to identify discursive strategies used by case managers to handle this dilemma. We also examine how these affect the participation of persons with dementia, and indicate implications of our study for social work practice and research.

Only two patients presented with classical symptoms of hyperthyroidism. Examination showed all patients had diffusely enlarged thyroids and exaggerated reflexes. Two patients showed Graves' opthalmopathy. These cases document the variety of presentations of hyperthyroidism. Hence, a high index of suspicion must exist for this disease, even in the absence of a number of the classical manifestations of hyperthyroidism. When patients present to primary care centers with a constellation of symptoms, an examination of the thyroid gland is essential. PMID:3694696

2017-03-01

Child sexual abuse is a worldwide public health issue. The objective of this study was to describe the demographic and clinical characteristics of children in cases of sexual abuse confirmed by material evidence at forensic examination. Cases of children younger than 12 years examined for suspected sexual abuse at the Institute of Forensic Medicine in Salvador, Bahia, Brazil, were reviewed retrospectively. The period evaluated was between 2005 and 2010. The inclusion criterion was the coroner's confirmation of sexual abuse based on material evidence. The mean age of the children in whom sexual abuse was confirmed was 8.2 (SD, 2.9) years, and 208 cases were female (83.9%). In 94% of the cases, the reason for carrying out the forensic examination was a report of sexual abuse. Less than 1% of the aggressors were female. A ruptured hymen was the finding that confirmed sexual abuse in 172 cases, corresponding to 83% of cases in girls. There were 2 cases of pregnancy. Recent anal or perianal lesions were present in 35 (87.5%) of the confirmed cases involving boys. Laboratory confirmation based on the detection of spermatozoa or prostate-specific antigen occurred in only 4.2% of cases. In all these cases, sample collection was performed within 24 hours of the alleged abuse. Thus, in the majority of cases with material evidence of sexual abuse, the confirmation criteria consisted of a ruptured hymen and recent perianal lesions.

Thirty-five cases of congenital lenticular dislocation seen in our Center since 1985 have been studied and analyzed clinically. By the survey of pedigrees and examination of these patients, including ocular, systemic, skeletal X-ray, psychocardiogram, and urinary sodium-nitroprusside test, 21 cases were diagnosed as Marfan's syndrome, 6 cases as simple ectopia lentis, 3 cases as Weill-Marchesani's syndrome, 4 cases as aniridia and 1 case as homecys tinuria. We found that the most significant ocular manifestation of congenital lenticular dislocation was reduction in visual acuity. The severity of visual disturbance varied with the types of dislocation and the visual deficiency was closely related to the intermediate-grade (II) dislocation of the lens. Examination of ERG showed normal function in most of the patients. From this, we believe that the major cause of visual reduction in congenital lenticular dislocation is lenticular myopia and astigmatism. There fore, early diagnosis and effective correction of vision should be emphasized to prevent the occurrence of amblyopia.

Place of laparoscopy in pelvic inflammatory disease.

Krishna, U R; Sheth, S S; Motashaw, N D

1979-06-01

577 laparoscopic examinations were performed in women presenting with sterility, chronic abdominal pain, primary or secondary amenorrhea, and irregular menstrual periods. 125 cases of chronic pelvic inflammatory disease (PID) of both the tuberculous and nonspecific varieties were detected through this procedure. 59 of the 125 cases were diagnosed as tuberculous. Investigations prior to laparoscopy had yielded significant results in only 12 cases. 87 of the 125 cases had no abnormal clinical findings, and only 18 of the 37 tubo-ovarian masses were diagnosed by bimanual examination. These results indicate that laparoscopy is an invaluable tool for the diagnosis of PID. It can reveal peritubal adhesions, tubercles on the tubes, small tubo-ovarian masses, and hydrosalpinx cases that cannot be detected clinically. It is considered a more suitable tool than culdoscopy, which less frequently notes adhesions to the fallopian tubes and pathological conditions in the upper pelvis. Laparoscopy can play an especially valuable role in India as a prelude to tuboplasty, given the high incidence of pelvic tuberculosis. Of the 316 cases of primary sterility examined in this study, 51 had genital tuberculosis and 39 had nonspecific PID. Laparoscopy can also be useful in disproving cases wrongly labelled as chronic pelvic disease. 15 women in this study who reported chronic lower abdominal pain had normal findings, and only 13 cases of PID were confirmed among the 33 cases preoperatively diagnosed as PID. A significant number of PID cases are attributed to operative procedures such as hysterosalpingography and ventrisuspension that are repeated unnecessarily and without proper sepsis. Thus, the possibility of a flare-up of infection during laparoscopy, especially due to hydroperturbation, should be considered. Women in this study who were found to have PID were given postoperative antibiotics. No significant postoperative complications were observed.

Objectives Healthcare leaders around the world are calling for radical, transformational change of our health and care systems. This will be a difficult and complex task. In this article, we examine case studies in which transformational change has been achieved, and seek to learn from these experiences. Methods We used the case study method to investigate examples of transformational change in healthcare. The case studies were identified from preliminary doctoral research into the transition towards future sustainable health and social care systems. Evidence was collected from multiple sources, key features of each case study were displayed in a matrix and thematic analysis was conducted. The results are presented in narrative form. Results Four case studies were selected: two from the US, one from Australia and one from the UK. The notable features are discussed for each case study. There were many common factors: a well communicated vision, innovative redesign, extensive consultation and engagement with staff and patients, performance management, automated information management and high-quality leadership. Conclusions Although there were some notable differences between the case studies, overall the characteristics of success were similar and collectively provide a blueprint for transformational change in healthcare. What is known about the topic? Healthcare leaders around the world are calling for radical redesign of our systems in order to meet the challenges of modern society. What does this paper add?

Few studies have addressed the relationship between dementia and crime. We conducted a study of persons who got a primary or secondary diagnosis of dementia or cognitive disorder in a forensic psychiatric examination. In Sweden, annually about 500 forensic psychiatric examinations are carried out. All cases from 2008 to 2010 with the diagnoses dementia or cognitive disorder were selected from the database of the Swedish National Board of Forensic Medicine. Out of 1471 cases, there were 54 cases of dementia or cognitive disorder. Case files were scrutinized and 17 cases of dementia and 4 cases of cognitive disorder likely to get a dementia diagnosis in a clinical setting were identified and further studied. There were 18 men and 3 women; Median age 66 (n = 21; Range 35-77) years of age. Eleven men but no women had a previous criminal record. There were a total of 38 crimes, mostly violent, committed by the 21 persons. The crimes were of impulsive rather that pre-meditated character. According to the forensic psychiatric diagnoses, dementia was caused by cerebrovascular disorder (n = 4), alcohol or substance abuse (n = 3), cerebral haemorrhage and alcohol (n = 1), head trauma and alcohol (n = 2), Alzheimer's disease (n = 2), Parkinson's disease (n = 1), herpes encephalitis (n = 1) and unspecified (3). Out of four persons diagnosed with cognitive disorder, one also had delusional disorder and another one psychotic disorder and alcohol dependence. An alcohol-related diagnosis was established in ten cases. There were only two cases of Dementia of Alzheimer's type, one of whom also had alcohol intoxication. None was diagnosed with a personality disorder. All but one had a history of somatic or psychiatric comorbidity like head traumas, stroke, other cardio-vascular disorders, epilepsy, depression, psychotic disorders and suicide attempts. In this very ill group, the suggested verdict was probation in one case and different forms of care in the remaining 20 cases instead of prison. Few cases of dementia or cognitive disorder were identified by forensic psychiatric examinations. All but one suffered from a variety of serious mental and medical conditions affecting the brain. Alcohol abuse was prevalent.

2017-02-01

To evaluate the diagnostic value of cytological greater omental milky spot examination for the diagnosis of peritoneal metastasis in gastric cancer patients. A total of 136 patients diagnosed with gastric cancer and without distant metastasis were enrolled in our study. All patients underwent laparoscopy and CH40 suspension liquid dye of peritoneal lymph nodes preoperatively as well as ascites or peritoneal lavage fluid collections and excisions of marked greater omental milky spot tissues perioperatively. According to the laparoscopic results, the patients were divided into T1-T2 stage (n = 56) without and into T3-T4 stage (n = 80) with tumor invasion into the serosal layer. Among the T1-T2-stage patients, tumor cells could be detected in peritoneal lavage fluids in 2 cases, whereas with greater omental milky spot examination, peritoneal metastasis was detected in 8 cases. Among the 80 cases in the T3-T4 stage, tumor cells could be detected in 28 cases via peritoneal lavage cytology and in 43 cases by greater omental milky spot examinations, and 4 cases had cancer cell infiltration also in nonmilky spot omental areas. The statistical analysis showed that the staging accuracy rate of exfoliative cytology examination was superior to that of the laparoscopic exploration (P < .05), but its sensitivity was significantly lower than that obtained with cytological greater omental milky spot examinations (P < .05). The laparoscopic exploration could make a preliminary diagnosis of peritoneal metastasis via serosal layer invasion detection. For further analyses, cytological examinations of greater omental milky spots were more sensitive than exfoliative cytology.

Aim of the study: To determine the circumstances which can be useful for offenders profiling in homicide cases with victim's body dismemberment. Material and methods: Study of all homicide cases with victim's corpse dismemberment examined in Krakow Department of Forensic Medicine over the last 50 years. Results: Within the past 50 years, a total number of 30 cases of homicides with dismembered bodies were examined in Krakow. 22 cases represent defensive mutilations performed by offender, 3 cases can be classified as offensive muti-lations and 3 cases represent aggressive mutilations - decapitation as a method of committing homicide. In this period the only 1 case of necrophilic mutilations was examined, when the body was dismembered without murder. In most cases the background of homicide was the family conflict, 6 was cause of mental illness of perpetrator and in 3 was sexual motive. Only in 3 cases (from 25 when the offender was known) perpetrator kill a stranger. In the other the offender belonged to the family or friends of the victim. In all cases where the perpetrator was determined, homicide and dismemberment was performed in his place of residence. The findings of the Police investigations indicate that in most cases homicides were not planned, occurred under the influence of emotion, only two have been previously scheduled. Conclusions: Homicides with corpses dismemberment usually are committed by offenders who is in close relationship with victim (family or friend). Dismemberment is almost always performed in the same place as murder - home of perpetrator. This type of homicide usually is not planned.

Introduction Paediatric lung sound recordings can be systematically assessed, but methodological feasibility and validity is unknown, especially from developing countries. We examined the performance of acoustically interpreting recorded paediatric lung sounds and compared sound characteristics between cases and controls. Methods Pneumonia Etiology Research for Child Health staff in six African and Asian sites recorded lung sounds with a digital stethoscope in cases and controls. Cases aged 1–59 months had WHO severe or very severe pneumonia; age-matched community controls did not. A listening panel assigned examination results of normal, crackle, wheeze, crackle and wheeze or uninterpretable, with adjudication of discordant interpretations. Classifications were recategorised into any crackle, any wheeze or abnormal (any crackle or wheeze) and primary listener agreement (first two listeners) was analysed among interpretable examinations using the prevalence-adjusted, bias-adjusted kappa (PABAK). We examined predictors of disagreement with logistic regression and compared case and control lung sounds with descriptive statistics. Results Primary listeners considered 89.5% of 792 case and 92.4% of 301 control recordings interpretable. Among interpretable recordings, listeners agreed on the presence or absence of any abnormality in 74.9% (PABAK 0.50) of cases and 69.8% (PABAK 0.40) of controls, presence/absence of crackles in 70.6% (PABAK 0.41) of cases and 82.4% (PABAK 0.65) of controls and presence/absence of wheeze in 72.6% (PABAK 0.45) of cases and 73.8% (PABAK 0.48) of controls. Controls, tachypnoea, >3 uninterpretable chest positions, crying, upper airway noises and study site predicted listener disagreement. Among all interpretable examinations, 38.0% of cases and 84.9% of controls were normal (p<0.0001); wheezing was the most common sound (49.9%) in cases. Conclusions Listening panel and case–control data suggests our methodology is feasible, likely valid and that small airway inflammation is common in WHO pneumonia. Digital auscultation may be an important future pneumonia diagnostic in developing countries. PMID:28883927

[Clinical symptoms and signs in Kimmerle anomaly].

PubMed

Split, Wojciech; Sawrasewicz-Rybak, Małgorzata

2002-01-01

The aim of the study was to consider Kimmerle anomaly (ponticulus posterior of the atlas) as an anatomic variant, which can cause a set of clinical symptoms and signs. A hundred and eight patients, 58 females and 50 males at the age of 18-59 years (M. 36.9 years, SD = 9.6) with radiologically verified Kimmerle anomaly were examined. A control group comprised 40 healthy subjects at the similar age range. The diagnosis of headaches was based on the criteria proposed by the IHS. A character of headaches, their localization, frequency, duration, number of days with headaches per year, circumstances associated with their onset and concomitant symptoms were evaluated. All the patients were subjected to electrophysiological studies (ENG, EEG and VEP). The results were statistically analyzed using a SPSS/PC+ computer system. It was revealed that clinical symptoms and signs in Kimmerle anomaly occurred most frequently in the third and fourth decade of life (65% of cases). These were most often tension-type headaches (50% of cases with headaches), vascular headaches (26% of cases) and neuralgia (24% of cases). Intensity of headaches was high. Headaches were accompanied by other complaints like vertigo (59% of cases) and in one third of cases--nausea. About 10% of patients also suffered from vomiting, paresthesia, dizziness, short periods of loss of consciousness. Sporadically--tinitus, drop attack, and vegetative symptoms. In cases without pain the most frequent signs were short periods of loss of consciousness, dizziness, and also nausea and dizziness. The EEG examination revealed pathology in 40% of patients with Kimmerle anomaly. The ENG examination in more than 33% of anomaly cases showed injury in the central part of vestibular system. Improper answers were reported in about 75% of the patients during the VEP examination.

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.

Selenium is an essential trace element obtained through diet that plays a critical role in DNA synthesis and protection from oxidative damage. Selenium intake and polymorphisms in selenoproteins have been linked to the risk of certain cancers though data for glioma are sparse. In a case-control study of glioma, we examined the associations of selenium in toenails and genetic variants in the selenoenzyme pathway with the risk of glioma and patient survival. A total of 423 genetic variants in 29 candidate genes in the selenoenzyme pathway were studied in 1547 glioma cases and 1014 healthy controls. Genetic associations were also examined in the UK Biobank cohort comprised of 313,868 persons with 322 incident glioma cases. Toenail selenium was measured in a subcohort of 300 glioma cases and 300 age-matched controls from the case-control study. None of the 423 variants studied were consistently associated with glioma risk in the case-control and cohort studies. Moreover, toenail selenium in the case-control study had no significant association with glioma risk (p trend = 0.70) or patient survival among 254 patients with high grade tumors (p trend = 0.70). The present study offers no support for the hypothesis that selenium plays a role in the onset of glioma or patient outcome. Copyright © 2018 Elsevier Ltd. All rights reserved.

Evaluation of the level of difficulty of patient cases for veterinary problem-solving examination: a preliminary comparison of three taxonomies of learning.

PubMed

Koskinen, Heli

2007-01-01

An important issue that has received insufficient attention in the use of problem-based learning in the medical curriculum is the mode of assessing the level of difficulty of patient cases. In the present study, the level of difficulty of case-based questions in a veterinary degree final examination in reproduction was evaluated. First, cognitive taxonomies were evaluated to clarify whether qualitative methods such as Bloom's taxonomy, the Structure of the Observed Learning Outcome (SOLO) taxonomy, and the Amsterdam Clinical Challenge Scale (ACCS) differed from each other as evaluation tools for problem-based cases. Using these taxonomies, 30 case-based questions from the final examination in reproduction in the Helsinki veterinary program were initially evaluated to determine which one was best suited to the evaluation of the difficulty of cases. In follow-up, the same cases were also evaluated by an experienced veterinary instructor in reproduction, with the aim of gaining insight into using these approaches to evaluating difficulty. It would appear, from this preliminary assessment, that the SOLO taxonomy may be the most suitable for evaluating the difficulty of patient cases, since the instructor's quality rating resembled more closely the SOLO than the Bloom taxonomy or the ACCS. It is to be emphasized that the purpose of this study was to provide a preliminary evaluation of possible approaches that might be used to assess patient-case difficulty. Resolving all issues will require a greater number of evaluations of all components.

2017-07-01

The purpose of this study was to determine the diagnostic accuracy of MRI for detecting acute appendicitis in pregnancy in a multi-institution study involving general body MR readers with no specific expertise in MR imaging of the pregnant patient. Retrospective review of MRI examinations on PACS in 42 pregnant patients was evaluated for acute right lower quadrant pain. Three fellowship-trained general body radiologists analyzed the MRI examinations in consensus and attempted to localize the appendix, assess for features of appendicitis, and exclude alternative etiologies for the right lower quadrant pain. Of the 42 MRI examinations, the readers noted 6 cases of acute appendicitis, 16 cases of a normal appendix, and 20 cases involving non-visualization of the appendix but where there were no secondary features of acute appendicitis. Based on the surgical data and clinical follow-up, there were 3 true-positive cases, 3 false-positive cases, 34 true-negative cases, and 2 false-negative cases of acute appendicitis on MRI. This yielded an accuracy of 88.1%, sensitivity of 60%, specificity of 91.9%, positive predictive value of 50%, and negative predictive value of 94.4% for the detection of acute appendicitis in the pregnant patient on MRI. Alternative etiologies for the right lower quadrant pain on MRI included torsion of an ovarian dermoid in 1 case and pyelonephritis in 1 case. MRI is an excellent modality for excluding acute appendicitis in pregnant patients presenting with right lower quadrant pain.

Postmortem audit in a paediatric cardiology unit.

Russell, G A; Berry, P J

1989-01-01

Postmortem examinations performed on 76 children with a clinical diagnosis of congenital heart disease were reviewed retrospectively and compared with the findings before death. Both operated and unoperated cases were studied over a three year period. Despite intensive investigation during life, there was a high rate of unsuspected abnormalities at necropsy (80%): 29 cases had undiagnosed additional cardiac anomalies or surgical flaws, which contributed to death in 13 cases. Defects in surgery were uncommon but permitted modification in surgical technique to avoid recurrence. Myocardial necrosis and pulmonary foreign body embolism were common findings, the importance of which is uncertain and requires further study for their prevention. Even in the most thoroughly investigated cases postmortem examination has a high yield of clinically important pathology which is undetected during life. Images PMID:2794078

Assessing the clinical utility of combined movement examination in symptomatic degenerative lumbar spondylosis.

The aim of this study is to report the development and validation of a low back computer-aided combined movement examination protocol in normal individuals and record treatment outcomes of cases with symptomatic degenerative lumbar spondylosis. Test-retest, following intervention. Self-report assessments and combined movement examination were used to record composite spinal motion, before and following neurosurgical and pain medicine interventions. 151 normal individuals aged from 20 years to 69 years were assessed using combined movement examination between L1 and S1 spinal levels to establish a reference range. Cases with degenerative low back pain and sciatica were assessed before and after therapeutic interventions with combined movement examination and a battery of self-report pain and disability questionnaires. Change scores for combined movement examination and all outcome measures were derived. Computer-aided combined movement examination validation and intraclass correlation coefficient with 95% confidence interval and least significant change scores indicated acceptable reliability of combined movement examination when recording lumbar movement in normal subjects. In both clinical cases lumbar spine movement restrictions corresponded with self-report scores for pain and disability. Post-intervention outcomes all showed significant improvement, particularly in the most restricted combined movement examination direction. This study provides normative reference data for combined movement examination that may inform future clinical studies of the technique as a convenient objective surrogate for important clinical outcomes in lumbar degenerative spondylosis. It can be used with good reliability, may be well tolerated by individuals in pain and appears to change in concert with validated measures of lumbar spinal pain, functional limitation and quality of life.

This study examined the case-specific characteristics associated with interobserver diagnostic agreement in atypical ductal hyperplasia (ADH) of the breast. Seventy-two test set cases with a consensus diagnosis of ADH from the B-Path study were evaluated. Cases were scored for 17 histological features, which were then correlated with the participant agreement with the consensus ADH diagnosis. Participating pathologists' perceptions of case difficulty, borderline features or whether they would obtain a second opinion were also examined for associations with agreement. Of the 2070 participant interpretations of the 72 consensus ADH cases, 48% were scored by participants as difficult and 45% as borderline between two diagnoses; the presence of both of these features was significantly associated with increased agreement (P < 0.001). A second opinion would have been obtained in 80% of interpretations, and this was associated with increased agreement (P < 0.001). Diagnostic agreement ranged from 10% to 89% on a case-by-case basis. Cases with papillary lesions, cribriform architecture and obvious cytological monotony were associated with higher agreement. Lower agreement rates were associated with solid or micropapillary architecture, borderline cytological monotony, or cases without a diagnostic area that was obvious on low power. The results of this study suggest that pathologists frequently recognize the challenge of ADH cases, with some cases being more prone to diagnostic variability. In addition, there are specific histological features associated with diagnostic agreement on ADH cases. Multiple example images from cases in this test set are provided to serve as educational illustrations of these challenges. © 2016 John Wiley & Sons Ltd.

This case-prevention of adolescent suicide-is one of a series of teaching cases in the Case-Based Series in Population-Oriented Prevention (C-POP). It has been developed for use in medical school and residency prevention curricula. The complete set of cases is presented in this supplement to the American Journal of Preventive Medicine. This teaching case examines the issue of prevention of adolescent and young adult suicide both at an individual and at a population or community level, using data from the Onondaga County Health Department. In the first section of the case, students are asked to determine whether five deaths related to falling or jumping at a local shopping mall should be considered to be suicidal deaths. Students then develop skills in the reporting as well as in the epidemiology of adolescent suicidal deaths in Onondaga County. As the case progresses, students analyze the results of a local surveillance study of suicidal attempts and ideation. The case concludes with students evaluating a hypothetical screening study intended to reduce the risk of suicidal death and discussing a research design to examine the effectiveness of this prevention strategy.

To investigate the association between the economic recession and the detection of advanced cases of pulmonary tuberculosis in Osaka city from 2007 to 2009. A repeated cross-sectional study. Osaka city has been the highest tuberculosis burden area in Japan. After the previous global financial crisis, the unemployment rate in Osaka prefecture has deteriorated from 5.3% in 2008 to 6.6% in 2009. During the study period, 3406 pulmonary tuberculosis cases were enrolled: 2530 males and 876 females; 1546 elderly cases (65 years and above) and 1860 young cases (under 65 years); 417 homeless cases and 2989 non-homeless cases. Patients' information included the sex, age, registry, health insurances, places of detection, sputum smear test results, patients' delay, doctors' delay and the grade of chest x-ray findings. They were statistically analysed between 2007 and 2008, two years before and just before the financial crisis, and between 2008 and 2009, just before and after the financial crisis. The total numbers of pulmonary tuberculosis cases were 1172 in 2007, 1083 in 2008 and 1151 in 2009. In health examinations for non-homeless people, higher number of cases in 2009 were sputum smear positive, had respiratory symptoms and showed advanced disease in chest x-rays than those in 2008, with a longer patients' delay. On the contrary, in health examination for homeless people, fewer cases of advanced pulmonary tuberculosis were found in 2009 than in 2008, with a shorter patients' delay. In clinical examinations, there was no trend towards a difference between non-homeless and homeless people. Although homeless people might be protected by public assistance, tuberculosis prevention and control need to be reinforced for the non-homeless population after the financial crisis.

2018-02-01

The present study is planned to discuss the clinical value of prenatal 3D ultra-sonic diagnosis on fetus hemivertebra deformity through the retrospective analysis of clinical data of fetus hemivertebra deformity. Selected 9 fetus hemivertebra deformity cases, which have been admitted to our hospital during the period from January, 2010 to January, 2016 as study samples, and analyzed their 2D and 3D ultrasonic examination data. 4 cases of the fetus hemivertebra deformity occurred at lumbar vertebra, 3 cases at thoracic vertebra, and 2 cases at thoracolumbar vertebra. There were scoliosis and opened spine bifida (OSB). In 7 cases, there was absence of ribs in fetus. The 2D ultrasonic image showed that: The echo at the center of fetus vertebral arch lesion was blurred or lost. The coronal section showed the deformity of the spine. There was obvious loss of the ossification center. From the cross section, we could see that the vertebral body of the fetus was shrinking and the edges were relatively blurred. The 3D ultrasonic image showed that: the echo at the ossification center of the fetus vertebra was relatively blurred, or even lost. The image also indicated scoliosis deformity of the spine. The vertebral body lesion could be accurately located. 9 cases of fetus hemivertebra deformity have been detected through examination. Labor inductions have been carried out after getting the permission from the family members. The X-ray examination of the fetus after labor induction showed that the diagnosis was correct. Prenatal ultra-sonic examination holds strong potential for the diagnosis of fetus hemivertebra deformity quite early and deserves further clinical evaluation with large sample size.

A historical examination of a nursing curriculum is a bridge between past and present from which insights to guide curriculum development can be gleaned. In this paper, we use the case study method to examine how the University of Victoria School of Nursing (UVic SON), which was heavily influenced by the ideology of second wave feminism, contributed to a change in the direction of nursing education from task-orientation to a content and process orientation. This case study, informed by a feminist lens, enabled us to critically examine the introduction of a "revolutionary" caring curriculum at the UVic SON. Our research demonstrates the fault lines and current debates within which a feminist informed curriculum continues to struggle for legitimacy and cohesion. More work is needed to illuminate the historical basis of these debates and to understand more fully the complex landscape that has constructed the social and historical position of women and nursing in Canadian society today.

Positive FAST without hemoperitoneum due to fluid resuscitation in blunt trauma.

PubMed

Slutzman, Jonathan E; Arvold, Lisa A; Rempell, Joshua S; Stone, Michael B; Kimberly, Heidi H

2014-10-01

The focused assessment with sonography in trauma (FAST) examination is an important screening tool in the evaluation of blunt trauma patients. To describe a case of a hemodynamically unstable polytrauma patient with positive FAST due to fluid resuscitation after blunt trauma. We describe a case of a hemodynamically unstable polytrauma patient who underwent massive volume resuscitation prior to transfer from a community hospital to a trauma center. On arrival at the receiving institution, the FAST examination was positive for free intraperitoneal fluid, but no hemoperitoneum or significant intra-abdominal injuries were found during laparotomy. In this case, it is postulated that transudative intraperitoneal fluid secondary to massive volume resuscitation resulted in a positive FAST examination. This case highlights potential issues specific to resuscitated trauma patients with prolonged transport times. Further study is likely needed to assess what changes, if any, should be made in algorithms to address the effect of prior resuscitative efforts on the test characteristics of the FAST examination.

Abdalla, Ebtesam M; El Desouky, Lubna M; Hassanein, Nargues M

2015-01-01

The aim of this study was to investigate the usefulness of postmortem external examination performed by an experienced clinical geneticist as an alternative to autopsy in countries with limited resources. We studied a consecutive cohort of couples seeking genetic counseling for fetal loss or perinatal death over a period of 3 years. The study involved 230 couples; only 57 of them submitted a fetus or dead neonate, for whom a meticulous postmortem clinical examination was performed by an experienced clinical geneticist. The diagnosis rate for the group of cases subjected to postmortem examination (57.9%) was much higher than that of the group that comprised cases for which diagnosis was made through evaluation of medical records (27.2%). Whenever fetal or neonatal autopsy is refused or is not feasible, a comprehensive fetal or perinatal postmortem external examination by an experienced clinical geneticist may be a reasonable substitute.

2015-01-01

The purpose of this national role and function study was to identify the essential activities and necessary knowledge areas for effective case manager practice from the perspective of those currently functioning in various care settings and across diverse professional disciplines. The national study covered all case management practices and/or work settings across the full continuum of health care. This cross-sectional descriptive study used the practice analysis method and online survey research design. It employed a purposive sample of case managers, in which 52,370 individuals received an invitation to participate. Data collection completed over a 4-week period, resulting in 7,668 useable survey responses (nearly a 15% response rate). The study identified the common activities and knowledge areas necessary for competent and effective performance of case managers, as is highlighted in this article, which is the first of a 2-part series on the role and function study. The results informed the needed update of the test specifications for the Certified Case Manager (CCM) certification examination, as will be delineated in Part 2 of the article series, to ensure that it continues to be substantiated in current practice. Of special note are the emergence of specific activity and knowledge domains in the area of case management ethical, legal, and practice standards, and an increase in the number of employers requiring certified case managers to fill vacant positions and compensating them financially for such qualifications. This study helps keep the CCM credentialing examination evidence-based and maintain its validity for evaluating competency of case managers. Specifically, the study identified essential activities and knowledge domains that define competent case management practice. Findings can be used for developing programs and curricula for the training and development of case managers. The study instrument also can be used for further research of case management practice.

Sudden infant death syndrome caused by poliomyelitis.

PubMed

Dunne, J W; Harper, C G; Hilton, J M

1984-07-01

Most seemingly well infants who die suddenly and unexpectedly have no adequate cause of death found on thorough postmortem examination. Respiratory and enteric viruses are often present, especially in the upper respiratory tract, but the infective process seems, of itself, insufficient to cause death. In the remainder of the cases, a variety of lesions will be discovered, including viral myocarditis, bronchiolitis, and sepsis. We report a case of sudden and unexpected death in a 5-week-old male infant due to acute anterior poliomyelitis. This case illustrates the importance of a thorough postmortem examination, including histologic studies of the brain stem and spinal cord in cases of sudden infant death syndrome.

Following a natural experiment of guideline adaptation and early implementation: a mixed-methods study of facilitation

PubMed Central

2012-01-01

Background Facilitation is emerging as an important strategy in the uptake of evidence. However, it is not entirely clear from a practical perspective how facilitation occurs to help move research evidence into nursing practice. The Canadian Partnership Against Cancer, also known as the 'Partnership,' is a Pan-Canadian initiative supporting knowledge translation activity for improved care through guideline use. In this case-series study, five self-identified groups volunteered to use a systematic methodology to adapt existing clinical practice guidelines for Canadian use. With 'Partnership' support, local and external facilitators provided assistance for groups to begin the process by adapting the guidelines and planning for implementation. Methods To gain a more comprehensive understanding of the nature of facilitation, we conducted a mixed-methods study. Specifically, we examined the role and skills of individuals actively engaged in facilitation as well as the actual facilitation activities occurring within the 'Partnership.' The study was driven by and builds upon a focused literature review published in 2010 that examined facilitation as a role and process in achieving evidence-based practice in nursing. An audit tool outlining 46 discrete facilitation activities based on results of this review was used to examine the facilitation noted in the documents (emails, meeting minutes, field notes) of three nursing-related cases participating in the 'Partnership' case-series study. To further examine the concept, six facilitators were interviewed about their practical experiences. The case-audit data were analyzed through a simple content analysis and triangulated with participant responses from the focus group interview to understand what occurred as these cases undertook guideline adaptation. Results The analysis of the three cases revealed that almost all of the 46 discrete, practical facilitation activities from the literature were evidenced. Additionally, case documents exposed five other facilitation-related activities, and a combination of external and local facilitation was apparent. Individuals who were involved in the case or group adapting the guideline(s) also performed facilitation activities, both formally and informally, in conjunction with or in addition to appointed external and local facilitators. Conclusions Facilitation of evidence-based practice is a multifaceted process and a team effort. Communication and relationship-building are key components. The practical aspects of facilitation explicated in this study validate what has been previously noted in the literature and expand what is known about facilitation process and activity.

1984-12-01

Dysfunction of the pharyngo-oesophageal sphincter may escape detection by clinical examination, endoscopy, and routine barium studies. Cineradiographic examination of 300 patients with unexplained dysphagia revealed 57 cases of pharyngo-oesophageal dysfunction. In 25 cases an underlying disorder could be found, and 32 cases were considered idiopathic. Radiologically 3 types of dysfunction may be distinguished, namely late opening, incomplete relaxation, and early contraction of the pharyngo-oesophageal sphincter. Cineradiography was found to be an easy and reliable method of detecting pharyngo-oesophageal sphincter dysfunction.

2016-06-01

The aim of the study was to investigate the potential role of chest tomosynthesis (CTS) at a tertiary referral centre by exploring to what extent CTS could substitute chest radiography (CXR) and computed tomography (CT). The study comprised 1433 CXR, 523 CT and 216 CTS examinations performed 5 years after the introduction of CTS. For each examination, it was decided if CTS would have been appropriate instead of CXR (CXR cases), if CTS could have replaced the performed CT (CT cases) or if CT would have been performed had CTS not been available (CTS cases). It was judged that (a) CTS had been appropriate in 15 % of the CXR examinations, (b) CTS could have replaced additionally 7 % of the CT examinations and (c) CT would have been carried out in 63 % of the performed CTS examinations, had CTS not been available. In conclusion, the potential role for CTS to substitute other modalities during office hours at a tertiary referral centre may be in the order of 20 and 25 % of performed CXR and chest CT, respectively. © The Author 2016.

Evidence of virtual patients as a facilitative learning tool on an anesthesia course.

PubMed

Leung, Joseph Y C; Critchley, Lester A H; Yung, Alex L K; Kumta, Shekhar M

2015-10-01

Virtual patients are computerised representations of realistic clinical cases. They were developed to teach clinical reasoning skills through delivery of multiple standardized patient cases. The anesthesia course at The Chinese University of Hong Kong developed two novel types of virtual patients, formative assessment cases studies and storyline, to teach its final year medical students on a 2 week rotational course. Acute pain management cases were used to test if these two types of virtual patient could enhance student learning. A 2 × 2 cross over study was performed in academic year 2010-2011 on 130 students divided into four groups of 32-34. Performance was evaluated by acute pain management items set within three examinations; an end of module 60-item multiple choice paper, a short answer modified essay paper and the end of year final surgery modified essay paper. The pain management case studies were found to enhanced student performance in all three examinations, whilst the storyline virtual patient had no demonstrable effect. Student-teaching evaluation questionnaires showed that the case studies were favored more than the storyline virtual patient. Login times showed that students on average logged onto the case studies for 6 h, whereas only half the students logged on and used the storyline virtual patient. Formative assessment case studies were well liked by the students and reinforced learning of clinical algorithms through repetition and feedback, whereas the educational role of the more narrative and less interactive storyline virtual patient was less clear .

Effect of Periodontal Disease on Preeclampsia

Sayar, F; Hoseini, M Sadat; Abbaspour, S

2011-01-01

Background: A lot of studies have shown periodontal diseases as a risk factor for adverse pregnancy outcomes. The association between periodontitis and preeclampsia has been studied recently with controversy. Considering the importance of preventing preeclampsia as a dangerous and life-threatening disease in pregnant women, the present study was carried out. Methods: Two hundred and ten pregnant women participated in this case-control study (105 controls & 105 cases) during years 2007 and 2008. Preeclamptic cases were defined as blood pressure ≥140/90mmHg and proteinuria +1. Control group were pregnant women with normal blood pressure without proteinuria. Both groups were examined during 48 hours after child delivery. Plaque Index (PLI), Pocket Depth (PD), Clinical Attachment Level (CAL), Bleeding On Probing (BOP), Gingival Recession (GR) were measured on all teeth except for third molars and recorded as periodontal examination. Data was analyzed using t-test, chi-square, and Mann-Whitney U statistical tests. Results: There was no significant difference between the two study groups for PD. CAL, GR, BOP significantly increased in the case group (P< 0.02). This study showed that preeclamptic cases were more likely to develop periodontal disease (P< 0.0001). Eighty three percent of the control group and 95% of the case group had periodontal disease (P< 0.005) which had shown that preeclamptic cases were 4.1 times more likely to have periodontal disease (OR= 4.1). Conclusion: Preeclamptic cases significantly had higher attachment loss and gingival recession than the control group. PMID:23113094

To study the efficiency of a methodology for the active detection of coronary heart disease (CHD) and cerebrovascular diseases (CVD) during medical examination and to determine the need and possible ways of its improvement. The medical examinations of 19.4 million people (94.6% of all the citizens who had undergone medical examinations in all the regions of Russia in 2013) were analyzed and the methodological aspects of identification of the circulatory diseases (CDs) that were induced by coronary and cerebral vessel atherosclerosis and had common risk factors, primarily CHD and CVD, were assessed. The medical examinations revealed 2,915,445 cases of CDs and their suspicions, during which its clinical diagnosis was established in 57.2%. The suspected disease requiring that its diagnosis should be further specified; off-medical examinations revealed hypertension in more than 770,000 cases, CHD in 232,000, and CVD in 146,000. The proportion of stable angina pectoris of all angina cases was much higher at a young age (25.6%) than at middle (15.6%) and elderly (11.3%) ages. Brachiocephalic artery stenoses were detected in almost 13,000 cases. According to the official health statistics, within the years preceding the introduction of large-scale medical examinations, there was a slight rise in new CD cases among the adult population of Russia, which was more significant in 2013 (according to the preliminary data) than in 2012. The methodology for the active detection of CDs through a two-step medical examination, which is used during a follow-up, makes it possible to substantially increase detection rates for CDs. There has been shown to be a need for the better quality and completeness of diagnostic examination in real practice.

Trends in child sexual abuse cases referred for forensic examination in Southern Denmark from 2000 to 2011 - Did the 'Tønder-case' have an impact?

PubMed

Skovmand, Sofie; Astrup, Birgitte Schmidt

2015-11-01

In 2005 a serious case of child sexual abuse from the region of Southern Denmark was revealed to the Danish public. The case became known as the 'Tønder-case'. It was the first in a series of 4-5 serious cases of child maltreatment in Denmark, cases which spurred heavy public debate. In this study all the cases of child sexual abuse referred for forensic examination in a 12 year period, a total of 368 cases, were systematically evaluated. In order to identify any trends that could be correlated to an impact of the 'Tønder-case', cases from 2000 to 2002 and cases from 2009 to 2011 underwent an in-depth analysis. In the 12 year period there was a significant increase in numbers of cases. In the subgroups, comprised of 113 cases meeting the inclusion criteria, we found a significant increase in the frequency of cases involving incest and systematic abuse, as well as an uncorrelated increase in the frequency of cases where children were placed in foster care prior to the examination. These results were countered by a significant decrease in the number cases police reported child sexual abuse in the same period. The possible impact that cases like the 'Tønder-case' and the following press coverage may have on disclosure and the handling of this type of case by authorities is discussed, as well as further perspectives of extensive press coverage.

2011-06-01

As an illustration of the complexities involved in connecting physics and molecular biology at the nanoscale, in this paper I discuss two case studies from nanoscience. The first examines the use of a biological structure (DNA) to build nanostructures in a controlled way. The second discusses the attempt to build a single molecular wire, and then decide whether such a wire is indeed conducting. After presenting the central features of each case study, I examine the role played in them by microscopic imaging, the different styles of reasoning involved, and the various theoretical, methodological, and axiological differences. I conclude by arguing that, except for the probe microscopes that are used, there is very little in common between the two cases. At the nanoscale, physics and molecular biology seem to meet in a non-unified way. Copyright © 2010 Elsevier Ltd. All rights reserved.

Mild balanoposthitis.

PubMed Central

Fornasa, C V; Calabrŏ, A; Miglietta, A; Tarantello, M; Biasinutto, C; Peserico, A

1994-01-01

AIM--To identify and study cases of mild balanoposthitis (MBP) with penile pathology among patients observed at a dermatology clinic over an 18-month period. MATERIALS--The study included 321 patients with penile pathology. The term MBP was used to describe balanoposthitis of a localised, inflammatory nature with few, non-specific symptoms and a tendency to become chronic or recur. Two hundred and seventy had diseases clearly identifiable by clinical examination or laboratory tests; 51 cases were diagnosed as MBP and these patients had blood tests (to evaluate immune status) and microbiological examination; when these proved negative, a series of patch tests was also used. RESULTS--Of the 51 patients diagnosed as having MBP, the cause was ascertained in 34 cases (infection, mechanical trauma, contact irritation, contact allergy, etc.), whereas no specific aetiological factor was detected to explain the symptoms in the remaining 17 cases.

Park, Jae Hyun; Putrus, Raphael R; Pruzansky, Dawn P; Grubb, John

2017-03-01

The objective of this study was to identify the board certification protocols that hospital and university-based postgraduate orthodontic programs have in place to prepare residents for the American Board of Orthodontics (ABO) certification examination. An electronic survey was sent to the program directors of each of the 72 postgraduate orthodontic programs in the United States and Canada. The survey consisted of 49 questions about demographics, resident case assignment protocols, and ABO examination preparation methods. The response rate was 81%. Most programs were 30 to 36 months in length (72.7%). Many residents had a case load of 51 to 75 during their first year (50.9%), with an average maximum case load of 70 to 109. There was a positive correlation with both the number of cases that first-year residents start and the length of the program (Spearman correlation coefficient = 0.379; P <0.01) when compared with maximum case load. Approximately 72% of the programs do not offer a written mock board examination; however, 72% reported offering a clinical mock board examination. ABO cases are identified within the first 6 months of most programs. About 88% of respondents believe that residents take advantage of the banking system, and that over the past 5 years ABO Initial Certification Examination applications have increased. Most program directors (89.1%) believe that their program length is sufficient for board preparation. Subjects tested in the written examination are integrated into the didactic curriculum and strengthened with ongoing literature reviews, with a passing rate over 90%. Clinical examination preparation varies, with most programs requiring a mock board examination for graduation. Total participation in both the Initial Certification Examination and banking has increased since 2010; better follow-up protocols are needed to track residents after graduation.

Effect of digital problem-based learning cases on student learning outcomes in ophthalmology courses.

PubMed

Kong, Jun; Li, Xiaoyan; Wang, Youdong; Sun, Wei; Zhang, Jinsong

2009-09-01

To assess the impact of digital problem-based learning (PBL) cases on student learning in ophthalmology courses. Ninety students were randomly divided into 3 classes (30 students per class). The first class studied under a didactic model. The other 2 classes were divided into 6 groups (10 students per group) and received PBL teaching; 3 groups studied via cases presented in digital form and the others studied via paper-form cases. The results of theoretical and case analysis examinations were analyzed using the chi(2) test. Student performance on the interval practice was analyzed using the Kruskal-Wallis test. Questionnaires were used to evaluate student and facilitator perceptions. Students in the digital groups exhibited better performance in the practice procedures according to tutorial evaluations compared with the other groups (P < .05). The 2 PBL classes had significantly higher mean results of theoretical and case analysis examinations (P < .001), but there was no significant difference between the 2 PBL classes. Ninety-three percent of students in the digital groups (vs 73% in the paper groups) noted that the cases greatly stimulated their interest. Introducing PBL into ophthalmology could improve educational quality and effectiveness. Digital PBL cases stimulate interest and motivate students to further improve diagnosis and problem-handling skills.

Inter-rater reliability and generalizability of patient note scores using a scoring rubric based on the USMLE Step-2 CS format.

PubMed

Park, Yoon Soo; Hyderi, Abbas; Bordage, Georges; Xing, Kuan; Yudkowsky, Rachel

2016-10-01

Recent changes to the patient note (PN) format of the United States Medical Licensing Examination have challenged medical schools to improve the instruction and assessment of students taking the Step-2 clinical skills examination. The purpose of this study was to gather validity evidence regarding response process and internal structure, focusing on inter-rater reliability and generalizability, to determine whether a locally-developed PN scoring rubric and scoring guidelines could yield reproducible PN scores. A randomly selected subsample of historical data (post-encounter PN from 55 of 177 medical students) was rescored by six trained faculty raters in November-December 2014. Inter-rater reliability (% exact agreement and kappa) was calculated for five standardized patient cases administered in a local graduation competency examination. Generalizability studies were conducted to examine the overall reliability. Qualitative data were collected through surveys and a rater-debriefing meeting. The overall inter-rater reliability (weighted kappa) was .79 (Documentation = .63, Differential Diagnosis = .90, Justification = .48, and Workup = .54). The majority of score variance was due to case specificity (13 %) and case-task specificity (31 %), indicating differences in student performance by case and by case-task interactions. Variance associated with raters and its interactions were modest (<5 %). Raters felt that justification was the most difficult task to score and that having case and level-specific scoring guidelines during training was most helpful for calibration. The overall inter-rater reliability indicates high level of confidence in the consistency of note scores. Designs for scoring notes may optimize reliability by balancing the number of raters and cases.

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.

A Comparison of Strategies for Retinopathy of Prematurity Detection

PubMed Central

Prosser, Lisa A.; Wade, Kelly C.; Repka, Michael X.; Ying, Gui-shuang; Baumritter, Agnieshka; Quinn, Graham E.

2016-01-01

BACKGROUND AND OBJECTIVES: Delayed detection of type 1 retinopathy of prematurity (ROP) can lead to permanent visual impairment. Providing ROP examinations is challenging because of the limited ophthalmology workforce. This study compares digital imaging–based ROP detection strategies versus serial ROP examinations. METHODS: We conducted an individual-level microsimulation studyof a hypothetical cohort of 650 infants with gestational age from 23 to 30 weeks. Infants were evaluated by using strategies based on indirect ophthalmoscopy or digital imaging beginning at 32 weeks’ postmenstrual age (PMA) and continuing to discharge, transfer, or 40 weeks’ PMA. ROP status and the accuracy of digital imaging were based on the e-ROP (Telemedicine Approaches to Evaluating Acute-Phase ROP) study, which enrolled high-risk infants. RESULTS: Within the hypothetical NICU, the strategy of ROP examinations identified an average of 45.8 cases of type 1 ROP by discharge, transfer, or 40 weeks’ PMA, and another 1.9 cases were included in the group of infants recommended to have later follow-up. Digital imaging with an ROP examination at discharge identified all 47.7 cases of type 1 ROP. On average, the ROP examination–only strategy required 1745.7 ROP examinations, whereas digital imaging with a discharge examination required 1065.5 ROP examinations and 1786.2 digital imaging sessions. CONCLUSIONS: Although digital imaging decreased the number of ROP examinations per infant, there was an increase in the total number of interventions (ie, ROP examinations and imaging sessions). Providing an ROP examination at the time of NICU discharge can significantly reduce the number of infants who require follow-up. PMID:26672022

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

PubMed

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.

Inherited heart disease causing electric instability in the heart has been suggested to be a risk factor for sudden unexpected death in epilepsy (SUDEP). The purpose of this study was to reveal the correlation between epilepsy-related sudden unexpected death (SUD) and inherited heart disease. Twelve epilepsy-related SUD cases (seven males and five females, aged 11-78 years) were examined. Nine cases fulfilled the criteria of SUDEP, and three cases died by drowning. In addition to examining three major epilepsy-related genes, we used next-generation sequencing (NGS) to examine 73 inherited heart disease-related genes. We detected both known pathogenic variants and rare variants with minor allele frequencies of <0.5%. The pathogenicity of these variants was evaluated and graded by eight in silico predictive algorithms. Six known and six potential rare variants were detected. Among these, three known variants of LDB3, DSC2 and KCNE1 and three potential rare variants of MYH6, DSP and DSG2 were predicted by in silico analysis as possibly highly pathogenic in three of the nine SUDEP cases. Two of three cases with desmosome-related variants showed mild but possible significant right ventricular dysplasia-like pathology. A case with LDB3 and MYH6 variants showed hypertrabeculation of the left ventricle and severe fibrosis of the cardiac conduction system. In the three drowning death cases, one case with mild prolonged QT interval had two variants in ANK2. This study shows that inherited heart disease may be a significant risk factor for SUD in some epilepsy cases, even if pathological findings of the heart had not progressed to an advanced stage of the disease. A combination of detailed pathological examination of the heart and gene analysis using NGS may be useful for evaluating arrhythmogenic potential of epilepsy-related SUD. © 2016 International Society of Neuropathology.

Two similar cases of elderly women with moderate abdominal pain and pneumoperitoneum of unknown origin: a surgeon's successful conservative management.

Vinzens, Fabrizio; Zumstein, Valentin; Bieg, Christian; Ackermann, Christoph

2016-05-26

Patients presenting with abdominal pain and pneumoperitoneum in radiological examination usually require emergency explorative laparoscopy or laparotomy. Pneumoperitoneum mostly associates with gastrointestinal perforation. There are very few cases where surgery can be avoided. We present 2 cases of pneumoperitoneum with unknown origin and successful conservative treatment. Both patients were elderly women presenting to our emergency unit, with moderate abdominal pain. There was neither medical intervention nor trauma in their medical history. Physical examination revealed mild abdominal tenderness, but no clinical sign of peritonitis. Cardiopulmonary examination remained unremarkable. Blood studies showed only slight abnormalities, in particular, inflammation parameters were not significantly increased. Finally, obtained CTs showed free abdominal gas of unknown origin in both cases. We performed conservative management with nil per os, nasogastric tube, total parenteral nutrition and prophylactic antibiotics. After 2 weeks, both were discharged home. 2016 BMJ Publishing Group Ltd.

Parental and comorbid epilepsy in persons with bipolar disorder.

PubMed

Sucksdorff, Dan; Brown, Alan S; Chudal, Roshan; Jokiranta-Olkoniemi, Elina; Leivonen, Susanna; Suominen, Auli; Heinimaa, Markus; Sourander, Andre

2015-12-01

Population-based studies have demonstrated an overrepresentation of bipolar disorder (BPD) in individuals with epilepsy. However, few studies have examined the reverse association, i.e. comorbid epilepsy in individuals selected based on BPD diagnosis. No previous population-based study having examined the co-occurrence of BPD and epilepsy has adjusted for parental psychopathology. Such an adjustment is motivated by population-based studies reporting an overrepresentation of various types of parental psychiatric disorders in both BPD and epilepsy. Furthermore, an association between epilepsy in first-degree relatives and BPD has previously only been examined and demonstrated in a small clinical sample. The objective of this study is to examine the associations between parental and comorbid epilepsy and BPD, adjusting for parental psychopathology. This nested case-control study identified 1861 cases with BPD, age up to 25 years, 3643 matched controls, and their parents from Finnish national registers. Conditional logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs) and two-sided significance limits of p<0.05. BPD was associated with comorbid epilepsy (adjusted OR 2.53, 95% CI: 1.73-3.70) but not with parental epilepsy. Epilepsy was found in 3.33% of cases versus 1.29% of controls, 2.69% of cases' parents versus 2.53% of controls' parents. The diagnoses were register-based, not based on standardized procedures with direct ascertainment. An association between BPD and comorbid epilepsy persists even after adjusting for parental psychopathology. Lack of familial clustering of BPD and epilepsy would suggest that the elevated co-occurrence of these disorders is influenced by non-genetic factors. Copyright © 2015 Elsevier B.V.

Scientists' attitudes on science and values: Case studies and survey methods in philosophy of science.

PubMed

Steel, Daniel; Gonnerman, Chad; O'Rourke, Michael

2017-06-01

This article examines the relevance of survey data of scientists' attitudes about science and values to case studies in philosophy of science. We describe two methodological challenges confronting such case studies: 1) small samples, and 2) potential for bias in selection, emphasis, and interpretation. Examples are given to illustrate that these challenges can arise for case studies in the science and values literature. We propose that these challenges can be mitigated through an approach in which case studies and survey methods are viewed as complementary, and use data from the Toolbox Dialogue Initiative to illustrate this claim.

Bias correction of risk estimates in vaccine safety studies with rare adverse events using a self-controlled case series design.

PubMed

Zeng, Chan; Newcomer, Sophia R; Glanz, Jason M; Shoup, Jo Ann; Daley, Matthew F; Hambidge, Simon J; Xu, Stanley

2013-12-15

The self-controlled case series (SCCS) method is often used to examine the temporal association between vaccination and adverse events using only data from patients who experienced such events. Conditional Poisson regression models are used to estimate incidence rate ratios, and these models perform well with large or medium-sized case samples. However, in some vaccine safety studies, the adverse events studied are rare and the maximum likelihood estimates may be biased. Several bias correction methods have been examined in case-control studies using conditional logistic regression, but none of these methods have been evaluated in studies using the SCCS design. In this study, we used simulations to evaluate 2 bias correction approaches-the Firth penalized maximum likelihood method and Cordeiro and McCullagh's bias reduction after maximum likelihood estimation-with small sample sizes in studies using the SCCS design. The simulations showed that the bias under the SCCS design with a small number of cases can be large and is also sensitive to a short risk period. The Firth correction method provides finite and less biased estimates than the maximum likelihood method and Cordeiro and McCullagh's method. However, limitations still exist when the risk period in the SCCS design is short relative to the entire observation period.

Firearm injuries (FI) are the most common cause of death among military personnel. In this study, postmortem examination and autopsy records of deaths resulting from firearm injuries recorded in the Department of Forensic Medicine of Gulhane Military Medical Academy between 1993-2010 were examined retrospectively. We evaluated the characteristics of 153 firearm deaths accounting for 36.6% of all medical-legal autopsies. The cases included 152 men (99.3%) and 1 woman (0.7%). The mean age of the cases was 23.1 years (±4.7; range, 20-43 years). The manner of death was determined in all cases with 41.8% of cases identified as suicide and 39.9% as homicide. The most common sites of firearm entrance wounds were the head and neck region (n=109, 71.2%), the chest (n=26, 17%), or the abdomen (n=14, 9.2%). The type of firearm was not clear in most cases. In conclusion, complete forensic and medical records will facilitate the rapid and accurate conclusion of the legal process and will enhance future retrospective studies.

RESEARCH: Theory in Practice: Applying Participatory Democracy Theory to Public Land Planning

PubMed

Moote; Mcclaran; Chickering

1997-11-01

/ Application of participatory democracy theory to public participation in public land planning, while widely advocated, has not been closely examined. A case study is used here to explicate the application of participatory democracy concepts to public participation in public land planning and decision making. In this case, a Bureau of Land Management resource area manager decided to make a significant shift from the traditional public involvement process to a more participatory method-coordinated resource management (CRM). This case was assessed using document analysis, direct observation of CRM meetings, questionnaires, and interviews of key participants. These sources were used to examine the CRM case using participatory democracy concepts of efficacy, access and representation, continuous participation throughout planning, information exchange and learning, and decision-making authority. The case study suggests that social deliberation in itself does not ensure successful collaboration and that establishing rules of operation and decision making within the group is critical. Furthermore, conflicts between the concept of shared decision-making authority and the public land management agencies' accountability to Congress, the President, and the courts need further consideration.KEY WORDS: Case study; Coordinated resource management; Public participation; Administrative discretion; Representation; Consensus; Collaboration

Attributes of Successful Actions to Restore Lakes and ...

EPA Pesticide Factsheets

As more success is achieved in restoring lakes and estuaries from the impacts of nutrient pollution, there is increased opportunity to evaluate the scientific, social, and policy factors associated with achieving restoration goals. We examined case studies where deliberate actions to reduce nutrient pollution and restore ecosystems resulted in ecological recovery. Prospective cases were identified from scientific literature and technical documents for lakes and estuaries with: (1) scientific evidence of nutrient pollution; (2) restoration actions taken to mitigate nutrient pollution; and (3) documented ecologicalimprovement. Using these criteria, we identified 9 estuaries and 7 lakes spanning countries, climatic regions, physical types, depths, and watershed areas. Among 16 case studies ultimately included, 8 achieved improvements short of stated restoration goals. Five more were successful initially, but condition subsequently declined. Three of the case studies achieved their goals fully and are currently managing to maintain the restored condition. We examined each case to identify both common attributesof nutrient management, grouped into ‘themes’, and variations on those attributes, which were coded into categorical variables based on thorough review of documents associated with each case. The themes and variables were organized into a broad conceptual model illustrating how they relate to each other and to nutrient management outcomes. We then explored

Cost-benefit value of microscopic examination of intervertebral discs.

PubMed

Grzybicki, D M; Callaghan, E J; Raab, S S

1998-09-01

Given the virtual absence of histologically detected, clinically unsuspected disease in intervertebral disc specimens, some authors have advocated that histological examination be discontinued. However, the examination of intervertebral disc specimens remains common practice in most pathology laboratories. No cost-benefit analysis of this practice has been made; therefore, the authors' goal in this study was perform such an analysis. Using the University of Iowa surgical pathology database, 1109 patients who had undergone a laminectomy were identified retrospectively. These cases were classified into four categories based on the patients' preoperative clinical diagnosis and final histopathological diagnosis: insignificant clinical diagnosis/insignificant pathological diagnosis (ICIP), significant clinical diagnosis/insignificant pathological diagnosis (SCIP), significant clinical diagnosis/significant pathological diagnosis (SCSP), and insignificant clinical diagnosis/significant pathological diagnosis (ICSP). A significant clinical diagnosis was defined as one other than a benign, noninfectious indication for laminectomy. A significant pathological diagnosis was a diagnosis other than degenerative changes. The cost-benefit value of performing a histological examination in cases with significant or insignificant clinical diagnoses was examined. The cases were classified as: 1068 ICIP, 17 SCIP, 21 SCSP, and three ICSP. On chart review, in all three cases of ICSP an epidural abscess was identified perioperatively and the subsequent histological diagnosis did not affect patient care.

Glaucoma is the foremost cause of irreversible blindness, and more than 50% of cases remain undiagnosed. Our objective was to report the costs of a glaucoma detection programme operationalised through Philadelphia community centres. The analysis was performed using a healthcare system perspective in 2013 US dollars. Costs of examination and educational workshops were captured. Measures were total programme costs, cost/case of glaucoma detected and cost/case of any ocular disease detected (including glaucoma). Diagnoses are reported at the individual level (therefore representing a diagnosis made in one or both eyes). Staff time was captured during site visits to 15 of 43 sites and included time to deliver examinations and workshops, supervision, training and travel. Staff time was converted to costs by applying wage and fringe benefit costs from the US Bureau of Labor Statistics. Non-staff costs (equipment and mileage) were collected using study logs. Participants with previously diagnosed glaucoma were excluded. 1649 participants were examined. Mean total per-participant examination time was 56 min (SD 4). Mean total examination cost/participant was $139. The cost/case of glaucoma newly identified (open-angle glaucoma, angle-closure glaucoma, glaucoma suspect, or primary angle closure) was $420 and cost/case for any ocular disease identified was $273. Glaucoma examinations delivered through this programme provided significant health benefit to hard-to-reach communities. On a per-person basis, examinations were fairly low cost, though opportunities exist to improve efficiency. Findings serve as an important benchmark for planning future community-based glaucoma examination programmes. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Decision-making in palliative care: a reflective case study.

PubMed

Birchall, Melissa

2005-01-01

Critical examination of the processes by which we as nurses judge and reach clinical decisions is important. It facilitates the maintenance and refinement of good standards of nursing care and the pinpointing of areas where improvement is needed. In turn this potentially could support broader validation of nurse expertise and contribute to emancipation of the nursing profession. As pure theory, clinical decision-making may appear abstract and alien to nurses struggling in 'the swampy lowlands' (Schon 1983) of the realities of practice. This paper explores some of the key concepts in decision-making theory by introducing, then integrating, them in a reflective case study. The case study, which examines a 'snapshot' of the patient and practitioner's journey, interwoven with theory surrounding clinical decision-making, may aid understanding and utility of concepts and theories in practice.

Temporal association of cannabis use with symptoms in individuals at clinical high risk for psychosis.

PubMed

Corcoran, Cheryl M; Kimhy, David; Stanford, Arielle; Khan, Shamir; Walsh, Julie; Thompson, Judy; Schobel, Scott; Harkavy-Friedman, Jill; Goetz, Ray; Colibazzi, Tiziano; Cressman, Victoria; Malaspina, Dolores

2008-12-01

Cannabis use is reported to increase the risk for psychosis, but no prospective study has longitudinally examined drug use and symptoms concurrently in clinical high risk cases. We prospectively followed for up to 2 years 32 cases who met research criteria for prodromal psychosis to examine the relationship between substance use and clinical measures. Cases with a baseline history of cannabis use (41%) were older, but did not differ in clinical measures. Longitudinal assessments showed these cases had significantly more perceptual disturbances and worse functioning during epochs of increased cannabis use that were unexplained by concurrent use of other drugs or medications. These data demonstrate that cannabis use may be a risk factor for the exacerbation of subthreshold psychotic symptoms, specifically perceptual disturbances, in high risk cases.

This study examines the relationship between service empowerment and recovery. Service empowerment is defined as the extent to which consumers participate in service decisions and the level of reciprocity and respect within the relationship with their case managers. Assessments were made from two perspectives: consumers and their case managers. Structural equation models were developed to examine the direct and indirect effects of service empowerment on four recovery outcomes: Quality of Life, Level of Functioning, Consumer-Reported Symptomatology, and Case Manager-Reported Symptomatology. Consumers' perceptions of service empowerment were the most powerful predictor of recovery outcomes across the four models. Consumers' and case managers' perceptions were related but the magnitude of the relationship was small, indicating that considerable differences exist between their perceptions of service empowerment.

In a prospective cohort study, examining all participants for incidence of the condition of interest may be prohibitively expensive. For example, the "gold standard" for diagnosing temporomandibular disorder (TMD) is a physical examination by a trained clinician. In large studies, examining all participants in this manner is infeasible. Instead, it is common to use questionnaires to screen for incidence of TMD and perform the "gold standard" examination only on participants who screen positively. Unfortunately, some participants may leave the study before receiving the "gold standard" examination. Within the framework of survival analysis, this results in missing failure indicators. Motivated by the Orofacial Pain: Prospective Evaluation and Risk Assessment (OPPERA) study, a large cohort study of TMD, we propose a method for parameter estimation in survival models with missing failure indicators. We estimate the probability of being an incident case for those lacking a "gold standard" examination using logistic regression. These estimated probabilities are used to generate multiple imputations of case status for each missing examination that are combined with observed data in appropriate regression models. The variance introduced by the procedure is estimated using multiple imputation. The method can be used to estimate both regression coefficients in Cox proportional hazard models as well as incidence rates using Poisson regression. We simulate data with missing failure indicators and show that our method performs as well as or better than competing methods. Finally, we apply the proposed method to data from the OPPERA study.

Park, Yoon Soo; Lukas, Rimas V.; Brorson, James R.

2015-01-01

Objectives: This study examines factors affecting reliability, or consistency of assessment scores, from an objective structured clinical examination (OSCE) in neurology through generalizability theory (G theory). Methods: Data include assessments from a multistation OSCE taken by 194 medical students at the completion of a neurology clerkship. Facets evaluated in this study include cases, domains, and items. Domains refer to areas of skill (or constructs) that the OSCE measures. G theory is used to estimate variance components associated with each facet, derive reliability, and project the number of cases required to obtain a reliable (consistent, precise) score. Results: Reliability using G theory is moderate (Φ coefficient = 0.61, G coefficient = 0.64). Performance is similar across cases but differs by the particular domain, such that the majority of variance is attributed to the domain. Projections in reliability estimates reveal that students need to participate in 3 OSCE cases in order to increase reliability beyond the 0.70 threshold. Conclusions: This novel use of G theory in evaluating an OSCE in neurology provides meaningful measurement characteristics of the assessment. Differing from prior work in other medical specialties, the cases students were randomly assigned did not influence their OSCE score; rather, scores varied in expected fashion by domain assessed.

Incidence of cysts and tumors associated with lower impacted third molars are very low prevalence, which might be because of the fact that most pathologies go unnoticed as many practitioners discard the erupted tissue after surgical removal of the impacted teeth rather than sending the tissue for histopathological examination. Our aim was to evaluate the patients who came for third molar surgical removal with due therapeutic prophylacis and an incidental finding. A proper study protocol both inclusion and exclusion criteria was strictly followed for all the cases, which were included in the study. The period of study was 6 years and the total number of cases assessed were 2778 patients out of which 70 cases reported pathology associated with the impacted third molars. Among 70 cases 61.4% were reported as cyst and tumors and 38.6% of the cases had chronic inflammatory reaction, including two cases with normal dental follicle. High incidence rate of pathology associated with third molar occurred between age group of 20 and 30 years older age groups showed very low incidence. Most common site of impaction was found to be left side of mandible and positions were vertical and distoangular impactions. Thus was male predominance in the younger groups. The examination is necessary whether the third molars impacted cases were symptomatic or asymptomatic PMID:26015725

Relationship between candidate communication ability and oral certification examination scores.

Structured case-based oral examinations are widely used in medical certifying examinations in the USA. These orals assess the candidate's decision-making skills using real or realistic patient cases. Frequently mentioned but not empirically evaluated is the potential bias introduced by the candidate's communication ability. This study aimed to assess the relationship between candidate communication ability and medical certification oral examination scores. Non-doctor communication observers rated a random sample of 90 candidates on communication ability during a medical oral certification examination. The multi-facet Rasch model was used to analyse the communication survey and the oral examination data. The multi-facet model accounts for observer and examiner severity bias. anova was used to measure differences in communication ability between passing and failing candidates and candidates grouped by level of communication ability. Pearson's correlations were used to compare candidate communication ability and oral certification examination performance. Candidate separation reliability values for the communication survey and the oral examination were 0.85 and 0.97, respectively, suggesting accurate candidate measurement. The correlation between communication scores and oral examination scores was 0.10. No significant difference was found between passing and failing candidates for measured communication ability. When candidates were grouped by high, moderate and low communication ability, there was no significant difference in their oral certification examination performance. Candidates' communication ability has little relationship to candidate performance on high-stakes, case-based oral examinations. Examiners for this certifying examination focused on assessing candidate decision-making ability and were not influenced by candidate communication ability.

Newman, Elana; Nelson, Summer D.; Nitiéma, Pascal; Pfefferbaum, Rose L.; Rahman, Ambreen

2014-01-01

This review of the literature on disaster media coverage describes the events, samples, and media formats studied and examines the association between media consumption and psychological outcomes. A total of 36 studies representing both natural and man-made events met criteria for review in this analysis. Most studies examined disaster television viewing in the context of terrorism and explored a range of outcomes including posttraumatic stress disorder (PTSD) caseness and posttraumatic stress (PTS), depression, anxiety, stress reactions, and substance use. There is good evidence establishing a relationship between disaster television viewing and various psychological outcomes, especially PTSD caseness and PTS, but studies are too few to draw definitive conclusions about the other media formats—newspapers, radio, and internet (including social media)—that have been examined. As media technology continues to advance, future research is needed to investigate these additional formats especially newer formats such as social media. PMID:25064691
