The impact of perinatal loss in maternity units: A psycholinguistic analysis of health professionals' reactions.

Perinatal loss has a strong emotional impact on health professionals working in maternity units. We aimed to study the impact of this experience on health professionals' language. We analyzed the answers of 162 health professionals (physicians and non-medical staff) who described their reactions to perinatal loss.

[Variations between 2 ECG as predictors of atrial fibrillation: Cohort study].

Objetive: To evaluate the association between delta variations in the parameters of 2 sinusal ECG with atrial fibrillation (AF) onset.

Method: Retrospective cohort of 9,975 adult patients and members of the prepaid system at Hospital Italiano de Buenos Aires from Argentina, who had at least 2 sinusal ECG between 2006 and 2011. Population was followed up for detection of AF.

Multivariate survival analysis of histological parameters and clinical presentation in canine cutaneous mast cell tumours.

The Patnaik histological grade is a good method for the prediction of long-term mast cell tumour behaviour but it is influenced by subjective inter-observer variations and intratumoral heterogeneity. The present study evaluated each of the histopathological parameters used to formulate Patnaik's grade in terms of prognosis and tested whether they have a different prognostic sensitivity, thereby disclosing which could be considered more useful in the prediction of tumour recurrence and patient survival. Clinical presentation (single or multiple tumours) was also considered as possible prognostic factor.

Prognostic value of intratumoral vessel density in cutaneous mast cell tumors of the dog.

The biological behaviour of canine cutaneous mast cell tumours (MCTs) is highly variable. The aim of this study was to investigate whether intratumoral microvessel density (IMVD), as an indicator of angiogenesis, was predictive of biological behaviour in MCTs of canine skin, and to relate this parameter to histological grade and other histomorphological features. IMVD was evaluated by immunohistochemical labelling of the endothelial marker factor VIII (Von Willebrand's factor)-related antigen in 32 primary cutaneous MCTs.

Occupational and environmental exposure to perchloroethylene (PCE) in dry cleaners and their family members.

Perchloroethylene exposure in 28 dry-cleaning establishments and in 25 homes occupied by dry cleaners in Modena, Italy, was investigated. Environmental air samples and alveolar air samples from dry cleaners (n = 60) and from their family members (n = 23) were collected. The degree of perchloroethylene on the dry-cleaning premises varied widely from establishment to establishment.
