RENEB Inter-Laboratory Comparison 2021: The FISH-Based Translocation Assay.

Translocation analysis using fluorescence in situ hybridization (FISH) is the method of choice for dose assessment in case of chronic or past exposures to ionizing radiation. Although it is a widespread technique, unlike dicentrics, the number of FISH-based inter-laboratory comparisons is small. For this reason, although the current Running the European Network of Biological and Physical retrospective Dosimetry (RENEB) inter-laboratory comparison 2021 was designed as a fast response to a real emergency scenario, it was considered a good opportunity to perform an inter-laboratory comparison using the FISH technique to gain further experience. The Bundeswehr Institute of Radiobiology provided peripheral blood samples from one healthy human volunteer. Three test samples were irradiated with blinded doses of 0, 1.2, and 3.5 Gy, respectively. Samples were then sent to the seven participating laboratories. The FISH technique was applied according to the standard procedure of each laboratory. Both, the frequency of translocations and the estimated dose for each sample were sent to the coordinator using a special scoring sheet for FISH. All participants sent their results in due time. However, although it was initially requested to send the results based on the full analysis, evaluating 500 equivalent cells, most laboratories only sent the results based on triage, with a smaller number of analyzed cells. In the triage analysis, there was great heterogeneity in the number of equivalent cells scored. On the contrary, for the full analysis, this number was more homogeneous. For all three samples, one laboratory showed outlier yields compared to the other laboratories. Excluding these results, in the triage analysis, the frequency of translocations in sample no. 1 ranged from 0 to 0.013 translocations per cell, and for samples no. 2 and no. 3 the genomic mean frequency were 0.27 ± 0.03 and 1.47 ± 0.14, with a coefficient of variation of 0.29 and 0.23 respectively. Considering only results obtained in the triage analysis for sample no. 1, all laboratories, except one, classified this sample as the non-irradiated one. For sample no. 2, excluding the outlier value, the mean reported dose was 1.74 ± 0.16 Gy indicating a mean deviation of about 0.5 Gy to the delivered dose of 1.2 Gy. For sample no. 3 the mean dose estimated was 4.21 ± 0.21 Gy indicating a mean deviation of about 0.7 Gy to the delivered dose of 3.5 Gy. In the frame of RENEB, this is the second FISH-based inter-laboratory comparison. The whole exercise was planned as a response to an emergency, therefore, a triage analysis was requested for all the biomarkers except for FISH. Although a full analysis was initially requested for FISH, most of the laboratories reported only a triage-based result. The main reason is that it was not clearly stated what was required before starting the exercise. Results show that most of the laboratories successfully discriminated unexposed and irradiated samples from each other without any overlap. A good agreement in the observed frequencies of translocations was observed but there was a tendency to overestimate the delivered doses. Efforts to improve the harmonization of this technique and subsequent exercises to elucidate the reason for this trend should be promoted.

[Consequences of the COVID-19 lockdown in patients with chronic diseases in Andalusia]. / Repercusiones del confinamiento por COVID-19 en pacientes crónicos de Andalucía.

OBJECTIVE: To understand the consequences of the COVID-19 pandemic lockdown on the self-care of people living with chronic diseases and on their self-perceived health, and to identify factors that may influence the management of their disease in emergency situations. METHOD: A qualitative study conducted in 2020 (March and April) in Andalusia (Spain) during the COVID-19 pandemic lockdown, through virtual focus groups, using the Zoom telematics tool. Three virtual focus groups were conducted, including 34 patients from Andalusia with different chronic conditions such as arthritis, diabetes, cardiovascular disease, inflammatory bowel disease, breast cancer and fibromyalgia. RESULTS: People with chronic diseases reported effects of the lockdown in relation to their emotional experience, their coping resources, the information they received, the difficulties to manage self-care, and the contact or access to health services. They also suggested some lessons learned for the future. The need for more and better information, patient training, involving patient associations, and improving telematics access to health services are the main areas for improvement to minimize the impact of future quarantines on the self-care and the health of people with chronic diseases. CONCLUSIONS: Besides the risk of contracting COVID-19, the difficulties encountered by people with chronic diseases during the lockdown include interferences in the self-care and the health care received. Health crisis situations demand more information, training for patients and improvements in the health services accessibility for patients with chronic conditions.

[Patient perceptions on healthcare safety]. / Percepción de los pacientes sobre la seguridad de la asistencia sanitaria.

BACKGROUND AND OBJECTIVE: Patient Safety is an issue of growing interest in healthcare politics and specialized bibliography, but there are limited studies that include the perspective of the public on healthcare safety. MATERIAL AND METHOD: Qualitative research performed in 4 Spanish Autonomous Regions, using focus groups and semi-structured interviews with patients and representatives of associations. Discourse analysis and result triangulation. RESULTS: For the patients interviewed, the concept of safety is not limited to absence of error, but includes aspects such as confidence, communication, information and participation. In the process of resolving of adverse events, an apologetic attitude by the professionals is considered a key element. Existing interventions such as protocols and notification systems are positively valued, at same time pointing out difficulties in the implementation process. As regards information, the patients demand that the professional is trained in communication skills. More participation in their own healthcare process and clinical management is considered appropriate, at same time, it was stated that few members of the public have the opportunity to participate in current safety policies. CONCLUSIONS: Regarding healthcare safety, patients and key agents indicate the importance of moving from a blame culture to a confidence culture.

[Grammatical readability of the package leaflets of the medicinal products most widely consumed and generating the highest expense in Spain during 2005]. / Legibilidad gramatical de los prospectos de los medicamentos de más consumo y facturación en España en 2005.

BACKGROUND: The manufacturers of medicinal products are responsible for providing consumers proper information on the use of such products. This information is set out in the package leaflets which, according to current legislation, must be easy for patients to read and understand. The purpose of this study is to analyse the linguistic/grammatical readability of the package leaflets of medicinal products through application of the Flesch formula. METHODS: The 30 medicinal products most widely consumed and the 30 which generated the highest expenditure during 2005 in Spain were selected. In line with the recommendations of the relevant literature, documents with a Flesch Index value of > or = 10 were considered readable. The grammatical readability was calculated by using the Flesch Index accessible through the Microsoft Office 2000 programme. RESULTS: Only 5 documents obtained an acceptable Flesch Index score (= 10), while 18 scored 0. Half of the values were under 2; 25% were 0 and 25% scored 6 or more. CONCLUSIONS: The data obtained reveal a low level of linguistic and grammatical readability in the package leaflets analysed. The syntax used on drafting the texts tends to use long words.

[Not Available]. / Perspectivas de la ciudadanía sobre necesidades y expectativas de información sanitaria.

BACKGROUND: Patients' need for health information is widely recognized. The aim of this study was to determine how patients currently receive and rate this information. Additionally, we aimed to identify the needs and expectations of citizens of the autonomous region of Andalusia in this regard. MATERIAL AND METHOD: We performed a qualitative research study involving semi-structured telephone interviews with participants. A total of 48 interviews were performed in people with different social and health profiles from a structural sample. The final selection of persons to be interviewed was made using the snow-ball sampling method. Interview material was analyzed by means of NUDIST vivo 1.1 software-aided content analysis. RESULTS: The interviewees reported receiving health information mainly from healthcare personnel. Supplementary information sources were the internet, associations and publications. The interviewees expressed different degrees of satisfaction with the health information received, depending on its understandability and the amount of detail provided. The persons interviewed reported that they would like to receive all the information possible on their health-illness-care process and would prefer this information to come mainly from physicians. CONCLUSIONS: Information about the health-illness-care process should center on practical issues. Physicians are the first and principal source of medical information and consequently communication skills should be promoted in this collective through training courses. Additionally, alternative sources of information used by citizens should be strengthened to provide high-quality health information.

[Chronic patient activation and their relationship with health professionals in Andalusia]. / La activación de pacientes crónicos y su relación con el personal sanitario en Andalucía.

BACKGROUND: To evaluate the (inter)relation between chronic patient activation and its relationship with health professionals in Andalusia. METHODS: Descriptive and quantitative study involving 258 chronic patients from the School of Patients, contacted by email. One hundred and forty-two answered the Patient Activation Measurement (PAM) and the chronic patient's experience (IEXPAC) questionnaires. Statistical analyses included correlation study and comparison of means. RESULTS: The mean of Patient Activation Measurement was 87 points (scale from 0 to 100) and IEXPAC scale was 5.3 (scale from 0 to 10), with a directly proportional relation between variables. Males and participants belonging to patients' associations had higher levels of activation. The relationship with health professionals was better among patients with primary education and with <10 years of chronic disease. In general, medical staff received better evaluation, yet nurses were considered more prone to encouraging relationships among patients. The dimensions with higher impact on patient activation were inter-professional coordination and the attention paid to treatment and medication. Feeling confident to communicate one's concerns had more impact on IEXPAC scale. CONCLUSIONS: The correlation observed between patient activation and its relationship with health professionals leads to the need to improve the involvement and self-management of chronic patients, as well as to strengthen improved professional coordination and patient-staff communication.

Ameloblastoma. Diagnosis by means of FNAB. Report of two cases.

INTRODUCTION: Ameloblastomas are the most frequent odontogenic tumors of the maxilla. In spite of their benign cytohistological appearance, they behave as invasive recurring tumors, with the possibility of metastasis. FNAB is a rapid, bloodless test that provides a pre-surgical diagnosis, thus, on occasions avoiding the need for diagnostic biopsies. We present the cytological characteristics of two cases of jugal recurrences of mandibular ameloblastomas diagnosed by FNAB, as well as their cytohistological correlation. CLINICAL CASES: Two patients, a 36-year-old woman, and a 62-year-old male who both attended with mandibular swelling of a few months evolution. In both cases the first diagnostic approximation was the histological study of the tumoral mass, together with the radiological studies. Following therapeutic extirpation both cases recurred. The diagnosis of the recurrences was established cytologically by means of FNAB. The cytologic smears revealed a granular background with isolated macrophages and giant multinucleate cells and an abundant epithelial cellularity of basaloid appearance arranged in cohesive groups forming images of peripheral palidasing, as well as small groups of squamous metaplastic cells. DISCUSSION: FNAB is considered to be a rapid, bloodless and reliable method for the diagnosis of ameloblastoma. The cytology of these tumors reveals components of the lesion that, in general, are sufficient for the diagnosis of ameloblastoma, especially in cases of recurrence.

Toxic megacolon: a rare presentation of primary lymphoma of the colon.

Primary colonic lymphoma is rare and accounts for less than 1% of colon malignancies. Moreover, diffuse neoplastic invasion of the colon is exceptional. This case describes a patient with primary non-Hodgkin's lymphoma of the colon presenting as toxic megacolon. This unique presentation is the first case reported in the literature of a diffuse colonic lymphoma diagnosed in the setting of a toxic megacolon. Histological confirmation was performed on the piece of colectomy.

Psammomatous melanotic schwannoma localized in the mediastinum: diagnosis by fine-needle aspiration cytology.

The cytological characteristics are presented in a case of psammomatous melanotic schwannoma localized in the mediastinum, diagnosed by fine-needle aspiration cytology (FNAC), with later histological confirmation. This lesion affected a 38-year-old male, with a tumor measuring 5 cm in diameter located in the posterior mediastinum in contact with the spinal cord, with erosion of the adjacent vertebra (T5), that caused constant pain localized in the right scapular region with an evolution of several weeks. The cytological characteristics of psammomatous melanotic schwannoma are discussed, along with the histological and immunohistochemical features of this infrequent neural tumor, which aid in establishing a differential diagnosis. The importance of a correct histological diagnosis of this tumor is of particular clinical relevance after having been identified as one of the possible components of Carney's complex. This possibility demands a meticulous patient exploration in search of any other components that make up this complex, given the aggressive character of some of them. These lesions could, if not detected early enough, produce fatal consequences for the patient, fundamentally in those patients with cardiac myxomas. In this case, following an exhaustive clinical examination there was no pathology associated with this complex. It is therefore considered to be an isolated psammomatous melanotic schwannoma, and not a part of Carney's complex.

[Pulmonary inflammatory pseudotumor. Its diagnosis by fine-needle aspiration puncture]. / Seudotumor inflamatorio pulmonar. Diagnóstico mediante PAAF.

Cytological characteristics are reported in the case of a 20-years-old male with pulmonary inflammatory pseudotumor (PIP) diagnosed by fine-needle aspiration (FNA) and later confirmed histologically. The patient presented a large tumor on the lower lobe of the right lung with hemoptysis, hemothorax and secondary acute anemia. The clinical-pathological profile of PIP are reviewed, along with diagnostic problems arising from the morpho-structural characteristics of the disease.

[The diagnostic value of liver aspiration puncture with echographic control]. / Valor diagnóstico de la punción aspiración hepática con control ecográfico.

OBJECTIVE: To correlate liver fine needle aspiration (FNA) diagnosis with histopathological diagnosis and clinical evolution. DESIGN: Retrospective analysis of liver FNA validity, evaluating sensitivity, specificity and predictive value of the method in correlation with the clinical evolution and biopsy results. RESULTS: Malignancy was diagnosed in 46 cases (20 hepatocarcinomas and 26 liver metastases), and benign lesions in 24 patients. Ten additional cases were excluded on the grounds of insufficient material or the impossibility of establishing clinico-histological correlation. There were 6 false-negatives and one false-positive. The overall accuracy of the method was 90% with a sensitivity of 88.2% and specificity of 94%. The positive and negative predictive values of the method were 97.8 and 75%, respectively. CONCLUSIONS: Liver FNA is efficient in cases of suspected liver tumoration. The technique proved particularly useful in the present series in diagnosing liver metastases, often allowing the establishing of tumor origin.

[Neoplasms of the Meckel diverticulum. Apropos of 2 new cases]. / Neoplasias del divertículo de Meckel. A propósito de dos nuevos casos.

We present two new cases of cancer in a Meckel's diverticulum, representing 3.3% of the complicated Meckel's diverticula encountered in our department. The first case was a carcinoid tumor encountered in a pathology study of an inflamed Meckel's diverticulum, and the second case was a leiomyosarcoma on a Meckel's diverticulum that presented as diverticular perforation. We emphasize the advanced age of the two patients and review the cases reported in Spain and in the Western literature.

[Perspective of informal caregivers on home care. Qualitative study with a computer program]. / La perspectiva de las cuidadoras informales sobre la atención domiciliaria. Un estudio cualitativo con ayuda de un programa informático.

BACKGROUND: A hot debate exists in our country as to the models of home care which must be developed. This study is aimed at ascertaining how the family caregivers of terminal cancer patients, of the elderly suffering from dementia and of individuals having undergone major operations in outpatient surgery programs rate the quality of the home care provided. METHODS: A phenomenological type qualitative study based on discussion groups (9), triangular groups (5) and in-depth interviews (22). This study was conducted in Andalusia throughout the 1999-2000 period. The subjects of the study were the main caregivers of patients provided with home care through the healthcare centers. The information must be analyzed by means of a Nudist-4 software-aided content analysis. The analysis variables were those of the Servqual model. RESULTS: For the caregivers of cancer patients, the most important aspects of the quality of the home care provided were the Response Capacity and Accessibility. This analysis revealed that the patients suffered pain but the pain was not controlled. Negative aspects hindering accessibility were the lack of home care coverage outside of regular working hours, the difficulty of getting in touch by phone, the length of time it takes for someone to come and the visits solely on request. The caregivers of patients having undergone major outpatient surgery want Security and Reliability. They complain of the short length of time within which the patients are released from the hospital and of the home care provided by the health care center. The caregivers of the elderly with dementia place top priority on being provided with the materials they need to take care of these patients. CONCLUSIONS: Caregivers' and patients' expectations differ, depending on health problems, therefore, the type of home care provided should vary, according to the health problems involved. It is necessary to develop a flexible model, capable of adapting to different patient needs and the diverse circumstances that affect family caregivers.

[Angio-invasive disseminated aspergillosis: autopsy diagnosis in leukemic patients]. / Aspergilosis diseminada angioinvasiva: diagnóstico necrópsico en pacientes leucósicos.

We report on two patients with acute lymphoblastic leukemia in induction chemotherapy, who developed a sepsis which led, in both cases, to death following the appearance of neurological symptoms suggesting CNS affectation. Autopsy revealed an angioinvasive disseminated aspergillosis affecting lungs, brain, myocardium, kidneys, thyroid glands in both cases, and endocardium, urinary bladder, lymph nodes, alimentary tract, nasal sinuses in one of the cases. Microbiology study of necropsic tissue showed Aspergillus flavusoryzae and likewise Candida albicans in one case. The latter finding suggest a combined fungal sepsis caused to candida and aspergillus.

[Simple thyroid cyst]. / Quiste simple de tiroides.

Simple or true thyroid cysts are very rare. We only have found one case in which colorless and acellular transparent fluid has been found by means of the fine needle aspiration puncture (FNAP). We report the case of a 33 year old female who first presented with a rapidly growing thyroid nodule. The thyroid scintigraphy revealed the existence of a cold nodule and the ultrasonography showed a lesion having a cystic appearance. The FNAP was performed and was both diagnostic and therapeutic in this case.

[Elaboration and validation of an informative document on adenoamigdalectomy for patients]. / Elaboración y validación de un documento informativo sobre adeno-amigdalectomía para pacientes.

BACKGROUND: Access to up-to-date and understandable health information is a growing citizen demand, as well as an ethical duty and a legal regulation. Written information reinforces information transmitted orally during the consultation and improves recall capacity. Adenoamigdalectomy is an intervention that affects a high number of patients, the majority from the child population that has a high emotional sensitivity, and it is experienced by parents with considerable anxiety. An informative guide on adenoamigdalectomy was elaborated and validated. The aim of this article is to describe the process of elaborating the document, emphasizing its validation and results. MATERIAL AND METHODS: The document was validated in three phases: A) Clinical content validated by professionals with a checklist and a consensus meeting; B) Analysis of grammatical legibility according to the Flesch index; C) Validation of lexical legibility with citizens by means of a validation guide and interviews. RESULTS: The validation by professionals and citizens was highly positive. The professionals stressed the accuracy of the content and corrected some imprecisions. They made suggestions concerning format, writing style and length. The citizens stressed understandable language, resolution of doubts, respectful tone and their satisfaction with the initiative. They also differed on aspects such as their opinion of the document's length. CONCLUSIONS: The validation of informative documents by both professionals and patients is a process of great interest. Lack of agreement in their analyses makes it clear why it is important to include both sectors. The document was improved by their contributions.
