Monosomy 15 in chronic myelomonocytic leukemia. description of a case and review of the literature

We report a 89-year-old female diagnosed with chronic myelomonocytic leukemia (CMMoL) presenting with a monosomy 15. To our knowledge, this is the second reported case of CMMoL with monosomy 15. On the other hand, monosomy 15 in complex karyotypes is a frequent chromosome aberration in myelodysplastic syndromes, particularly in refractory anemia with excess of blasts.     

Percepción de profesionales de la salud sobre la intervención grupal socioeducativa con mujeres que presentan síntomas somáticos sin causa orgánica

ObjectiveTo know the perception and opinion of primary care health professionals on the impact of non-medicalizing group educational intervention (GRUSE) with women who present somatic symptoms without organic cause.DesignQualitative phenomenological study.SettingPrimary care health centers in Andalusia, during 2017 and 2018.Participants and/or contextsTwenty-four health professionals, selected according to their level of involvement in the GRUSE strategy (socio-educational groups).MethodA qualitative methodology is applied, through the phenomenological method. The technique used to collect the information is the discussion group, and a content analysis is carried out on it. The software Atlas.ti 8.0 is used as a support resource for the analysis.ResultsHealth professionals highlight group work as a means of achieving change, and point to the importance of intervention as a non-medicalizing strategy. They perceive that the participants obtain some benefits: the improvement of their personal well-being, the increase of their self-esteem and self-determination, and the generation of social networks, benefits that also affect their immediate surroundings.ConclusionsIn the opinion of the professionals, the strategy has positive effects on women and does not mean an increase in resources for the health system. In addition, they express the importance of provide women with tools to cope with daily life problems derivates mostly from gender mandates of a patriarchal society.     

Inhibition of Amiodarone‐Induced Lung Fibrosis but not Alveolitis by Angiotensin System Antagonists

Abstract: Earlier work in this laboratory showed that amiodarone induces apoptosis in alveolar epithelial cells by a mechanism inhibitable by angiotensin system antagonists. A variety of recent studies suggests a critical role for alveolar epithelial cell apoptosis in the pathogenesis of lung fibrosis. On this basis we hypothesized that amiodarone‐induced alveolar epithelial cell apoptosis and lung fibrosis in vivo might be inhibitable by the angiotensin converting enzyme inhibitor captopril or the angiotensin receptor antagonist losartan. Amiodarone‐induced lung fibrosis was induced in male Wistar rats by oral adminstration over six months. Replicate groups of rats received captopril or losartan in addition to amiodarone. Apoptosis was detected by increased total lung activity of caspase 3 and in situ end labeling (ISEL) of fragmented DNA. Collagen was localized and quantitated by the picrosirius red technique. Alveolar epithelial cell apoptosis was detected in amiodarone‐treated animals as early as three weeks after the start of amiodarone administration; by six months exposure, the incidence of alveolar epithelial cell apoptosis was significantly reduced by coadministration of captopril or losartan. Alveolar wall collagen accumulation also was significantly attenuated by captopril (100%) or losartan (74%), but neither agent blunted the accumulation of alveolar macrophages evoked by amiodarone (5.3‐fold at 6 months). Lung neutrophil content was unchanged by amiodarone treatment for three weeks or six months. These results indicate that amiodarone induces alveolar epithelial cell apoptosis in vivo that is inhibitable by angiotensin antagonists. They also support the hypothesis that blockade of angiotensin formation or function attenuates amiodarone‐induced lung fibrosis irrespective of the severity of alveolitis.     

Caloric and rotatory chair test results in patients with Ménière's disease.

OBJECTIVES: To determine whether an association exists between the parameters of the caloric and rotatory chair tests in patients with unilateral Ménière's disease. METHODS: Patients with unilateral Ménière's disease (n = 100) were subjected to the caloric and the rotatory chair test (sinusoidal harmonic acceleration and impulsive tests) on the same day. Canal paresis and directional preponderance were assessed in the caloric test, and different variables were measured in the rotatory chair test based on the existence of abnormal parameters in the vestibulo-ocular reflex at two or three consecutive frequencies of those tested and on the time constant of the vestibulo-ocular reflex. STUDY DESIGN AND SETTING: A prospective study was conducted at a University hospital. RESULTS: An abnormal result in the caloric test was obtained from 73% of the patients. In the rotatory chair test, the most frequent abnormal findings involved increases in the normal phase lead at 2 consecutive frequencies tested (23%). There was a stronger association between an abnormal result in phase, gain, and/or symmetry at three adjacent frequencies and a pathological result in the caloric test. CONCLUSION: Very few of the criteria used to define the caloric and rotatory chair tests seem to be associated. This confirms previous knowledge that both tests examine vestibulo-ocular reflex by different ways. Only when vestibular dysfunction is severe enough (manifested by the finding of an abnormal result in at least three consecutive frequencies in the rotatory chair test), the caloric test is also found to be abnormal.     

Cognitive performance among cohorts of children exposed to a waste disposal site containing heavy metals in Chile

Between 1984 and 1998, people living in Arica were involuntarily exposed to metal-containing waste stored in the urban area. The study aims to determine whether children who lived near the waste disposal site during early childhood experienced negative effects on their cognitive development. The cognitive performance was assessed using the Wechsler Intelligence Scale for Children. The exposure variable was defined by the year of birth in three categories: (1) Pre-remediation (born before 1999); (2) During-remediation (born between 1999 and 2003); and (3) Post-remediation (born after 2003). In the crude analysis, a difference of 10 points in the IQ average was observed between the group born in the pre- (81.9 points) and post-remediation period (91.1 points). The difference between both groups was five times higher as compared to children of similar age and socioeconomic status in other cities of Chile. This result could be related with a period of high potential for exposure to this contaminated site.     

Analysis of quantitative and qualitative measures of attachment in patients with fibromyalgia: The influence on nursing care

Attachment has been associated to fibromyalgia; however, this relationship has not been studied from the perspective of nursing care. In this study, in which 146 women with fibromyalgia participated, higher scores for anxiety and depression were found among those with fearful attachment. Additionally, attachment, as a quantitative measure, has also been associated to the functional limitation of the patients. Therefore, we propose the inclusion of attachment in the care of patients with fibromyalgia.
