A fatal pseudo-tumour: disseminated basidiobolomycosis

BACKGROUND: Basidiobolomycosis is a rare disease caused by the fungus Basidiobolus ranarum, member of the class Zygomycetes, order Entomophthorales, found worldwide. Usually basidiobolomycosis is a subcutaneous infection but rarely gastrointestinal manifestations have been described; 13 adults and 10 children and a few retroperitoneal or pulmonary cases. In gastrointestinal basidiobolomycosis the colon is most frequently involved, usually presenting with subacute mild abdominal pain. In contrast to children only very few described adult patients had hepatic masses. Definitive diagnosis requires culture, serological testing can be helpful. The fungal morphology and the Splendore-Hoeppli phenomenon are characteristic histological features. There are no prominent risk factors. Usually surgery and prolonged antifungal therapy are required. CASE PRESENTATION: A 61 year old man presented with progressive left abdominal pain and constipation since a few months. Colonoscopy showed an obstructing tumour in the descending colon, and a hemicolectomy was performed. Histology showed inflammation, possibly caused by a fungal or parasitic infection, without definite identification of an organism. A few weeks postoperatively a CT scan made because of abdominal discomfort, revealed a livermass (6 cm). Treatment with metronidazole, directed against an amoebic liver abscess, was unsuccessful. He developed a marked eosinophilia (27.7%). A liver biopsy was performed and the patient was referred to a university hospital. A repeated CT scan showed a livermass of 9 cm diameter. Review of colon and liver biopsy samples showed extensive necrosis and histiocytes, multinucleated giant cells and numerous eosinophils. Grocott stained sections contained unusually large hyphae surrounded by strongly eosinophilic material in haematoxylin and eosin stained sections (Splendore-Hoeppli phenomenon). A presumptive diagnosis of Basidiobolus spp. infection was made and treated with amphotericin B (Itraconazol contra-indicated because of renal insufficiency). A few days later the patient died of a septic shock. After autopsy Basidiobolus ranarum was cultured from liver, gallbladder and colon. CONCLUSION: Our patient died of gastrointestinal basidiobolomycosis with an obstructing colon tumour and a large hepatic mass. This was a rare presentation of basidiobolomycosis and the second fatal case described worldwide

Pediatric patient asthma-related emergency department visits and admissions in Washington, DC, from 2001–2004, and associations with air quality, socio-economic status and age group

BACKGROUND: The District of Columbia (DC) Department of Health, under a grant from the US Centers for Disease Control and Prevention, established an Environmental Public Health Tracking Program. As part of this program, the goals of this contextual pilot study are to quantify short-term associations between daily pediatric emergency department (ED) visits and admissions for asthma exacerbations with ozone and particulate concentrations, and broader associations with socio-economic status and age group. METHODS: Data included daily counts of de-identified asthma-related pediatric ED visits for DC residents and daily ozone and particulate concentrations during 2001–2004. Daily temperature, mold, and pollen measurements were also obtained. After a cubic spline was applied to control for long-term seasonal trends in the ED data, a Poisson regression analysis was applied to the time series of daily counts for selected age groups. RESULTS: Associations between pediatric asthma ED visits and outdoor ozone concentrations were significant and strongest for the 5–12 year-old age group, for which a 0.01-ppm increase in ozone concentration indicated a mean 3.2% increase in daily ED visits and a mean 8.3% increase in daily ED admissions. However, the 1–4 yr old age group had the highest rate of asthma-related ED visits. For 1–17 yr olds, the rates of both asthma-related ED visits and admissions increased logarithmically with the percentage of children living below the poverty threshold, slowing when this percentage exceeded 30%. CONCLUSION: Significant associations were found between ozone concentrations and asthma-related ED visits, especially for 5–12 year olds. The result that the most significant ozone associations were not seen in the age group (1–4 yrs) with the highest rate of asthma-related ED visits may be related to the clinical difficulty in accurately diagnosing asthma among this age group. We observed real increases in relative risk of asthma ED visits for children living in higher poverty zip codes versus other zip codes, as well as similar logarithmic relationships for visits and admissions, which implies ED over-utilization may not be a factor. These results could suggest designs for future epidemiological studies that include more information on individual exposures and other risk factors

Psychological impact of visible differences in patients with congenital craniofacial anomalies

© 2015, Singh and Moss; licensee Springer. Background: Patients with craniofacial anomalies often have appearance concerns and related social anxiety which can affect their quality of life. This study assessed the psychological impact of facial and dental appearance in patients with craniofacial anomalies in comparison to a general population control group. Methods: The study involved 102 adult patients (51% male) with congenital craniofacial anomalies and 102 controls (49% male). Both groups completed the Nepali version of Derriford Appearance Scale (DAS) and the Psychological Impact of Dental Aesthetic Questionnaire (PIDAQ) in a clinical setting to assess appearance-related distress, avoidance, and anxiety. Results: There was a significant difference between patients and controls on both PIDAQ (mean score for patients 33.25 ± 9.45 while for controls 27.52 ± 5.67, p < 0.001) and DAS59 scores (mean score for patients 159.16 ± 31.54 while for controls 77.64 ± 6.57, p < 0.001), indicating that patients experienced greater negative psychological impact of living with their appearance (PIDAQ) and more appearance-related distress (DAS) than controls. DAS scores were not associated with gender. There was no association of the place of residence (rural vs. urban) with PIDAQ or DAS59 scores. Conclusions: There is a significant psychological impact of altered facial and dental appearance in patients with craniofacial anomalies compared to controls. There was no effect of locality (rural/urban) on the psychological impact of facial and dental appearance in patients

Consensus guidelines for the use and interpretation of angiogenesis assays

The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference

Physical health in adults born with cleft lip and/or palate: A whole of life survey in the United Kingdom

Objectives Previous research in the field of cleft lip and/or palate (CL/P) has indicated a high prevalence of common health concerns, functional difficulties, and additional conditions known to affect long-term physical health, cognitive development, and psychological well-being. The aim of the present study was to examine the self-reported physical health of a national sample of adults born with CL/P. Design Drawing upon previous literature, an online, mixed-methods survey was designed by the Cleft Lip and Palate Association in collaboration with the Centre for Appearance Research at the University of the West of England. A total of 207 eligible responses were received between July and October 2018. Qualitative data were analyzed using inductive content analysis, while quantitative data were analyzed using descriptive statistics. Results A considerable proportion of participants reported one or more comorbid conditions, including common health concerns, difficulties related to language and/or learning, unresolved speech and/or hearing issues, problems with vision, breathing difficulties, and concerns related to eating and drinking. Many participants were unaware of their entitlement to specialist treatment, and some had experienced difficulties accessing specialist services through their general practitioner (GP). Conclusions Individuals with CL/P may be at risk of physical health issues persisting into adulthood. The monitoring of physical symptoms from an early age is recommended, as is a routine physical assessment for adults returning to the CL/P service later in life. Education for both GPs and adults is warranted. Future studies could investigate the wider prevalence of comorbid conditions in CL/P, in order to better understand the longer-term health burden

Values related to professionalism in dental education at the University of Chile: Student and faculty perceptions

Objective It is recognised that professionalism should play a central role in dental education. However, its implementation into the curricula of dental schools is still limited. Our objective was to identify the main values related to professionalism based on the perceptions of students and faculty members from the Faculty of Dentistry, University of Chile. Methods A Dental Values Survey was validated and culturally adapted in order to guarantee the greatest possible internal validity. The adapted survey was administered to students and faculty members (416 and 225, respectively). The final survey contained 64 items rated on a Likert scale of 1-5. Each item was categorised according to five dimensions: Altruism, Consciousness, Personal Satisfaction, Quality of Life and Professional Status. The values were compared between faculty and students and among students at different courses. A values scale was constructed by selecting the five items with the highest average score for each dimension. Results Survey respondents composed 34.32% of the universe, of which 50.46% were faculty and 49.54% were students. Values associated with Altruism, Consciousness and Professional Status, were the highest rated by students and faculty. Values associated with Personal Satisfaction and Quality of Life received the lowest scores for both groups. Conclusions To provide the best possible attention to patients (Consciousness), and that patients have access to affordable dental care (Altruism), are the values at the top of our scale. On the other hand, to maintain financial stability and to be well paid (Quality of Life) were the less considered.Comision Nacional de Investigacion Cientifica y Tecnologic
