Objective To determine gender differences in prevalence of anx-
iety traits in general population and to evaluate its impact on the
risk of hypertension in men and women aged 25–64 years in the
open population in Russia/Siberia.
Methods Under the third screening of WHO program “MONICA-
psychosocial” a random representative sample of the population
aged 25–64 were surveyed in Novosibirsk in 1994 (n = 657 men,
n = 870 women). Anxiety levels were measured by means Spiel-
berger test. Over the 16-year period were identified 229 cases of
AH in women and 46 for men. Cox-proportional regression model
was used for an estimation of hazard ratio (HR).
Results In general population aged 25–64 years at 99.5% of
women and 97.5% of men had moderate and high levels of anxiety
traits. In univariate Cox regression analysis model the risk inci-
dence of arterial hypertension in women and men with high level
of anxiety was 2.383-fold and 5.18-fold higher, respectively, over 5
years of follow-up. It was 1.853-fold and 5.75-fold higher over 10
years and 1.45 and 3.82 times higher over 16 years after baseline.
In the multivariate Cox regression model HR of hypertension was
1648 in women with high level of anxiety; and it was 4.568-fold
higher in men.
Conclusion Despite the higher prevalence of HLA in women, the
risk of developing hypertension is much higher in males.

Introduction The Depression, Anxiety and Stress Scales are
widely used in clinical and non-clinical populations, both in
research and clinical settings. The need for briefer but valid and
reliable instruments has motivated the reduction of the original
42-item scale to a short 21-version. On Portuguese samples, Pais-
Ribeiro et al. (2004) found that the original 3-factor solution (stress,
anxiety and depression) explained 50.35% of the variance and in
an exploratory analysis; Xavier et al. (2015) presented a two fac-
tor solution and a modified three-factor solution with a sample of
pregnant women, both with adequate factors’ reliability (< 0.70)
and explaining above 50% of the variance.
Aims Based on the previous results of factor analysis with Por-
tuguese samples, the present study aimed to perform confirmatory
factor analyses (using Mplus software) to evaluate which dimen-
sional structure best fitted the data.
Methods The sample comprised 234 students (78.2% female),
between 18–26 years old (M= 20.55; SD = 1.66). Eighty-five percent
of the participants were on their first three years of college educa-
tion. Participants filled the Portuguese version of the DASS-21.
Results Our results showed that the original 3-factor structure
had the best model fit [ 2(186) = 475.465, P< 0.05; RMSEA = 0.082,
90% CI = 0.073–0.091; CFI = 0.918; TLI = 0.908; SRMR = 0.05]. Good
reliability was found for all subscales (0.92 for stress, 0.87 for anx-
iety and 0.91 for depression subscale).
Conclusions The DASS-21 is a reliable instrument that, with stu-
dent populations, seems to have better performance when used
with a 3-factor structure. Further research is needed to confirm
this structure in Portuguese clinical samples.

Introduction Psychogenic nonepileptic seizures (PNES) are
defined as a somatoformconversion disorder manifesting as parox-
ysmal events not associated with electroencephalographic (EEG)
epileptiform correlates. This entity is poorly understood and often
misdiagnosed as epilepsy. It is important to recognize that misdiag-
nosis leads to inappropriate use of antiepileptic drugs, which may
worsen the course of the disease.
Recent studies have suggested that the frequency of psychogenic
nonepileptic seizures ranges from 10 to 23% of referrals to a pedi-
atric epilepsy center, as well as 60% of children with PNES achieve
symptom improvement and event freedom of symptoms following
appropriate treatment.
Objectives The aim of this study is to conduct a literature review
of studies which the purpose was better understand the etiologies,
features, and care outcomes of psychogenic nonepileptic seizures
(PNESs) in a pediatric setting.
Conclusion A early identification of the risk factors for comorbid
psychopathology, diagnosis and appropriate care for PNESs reduces
inappropriate medical investigation and therapy, expedites rates
of remission, and decreases health-care utilization in a pediatric
setting.

Emetophobia (a specific phobia of
vomiting): A case study

Introduction Case presentation of a young woman Ms. A.M.,
referred by her GP with an eating disorder, who was thereafter
diagnosed with an uncommon type of phobia (emetophobia – a
specific phobia of vomiting) and treated accordingly.
Objectives To highlight the diagnostic dilemma with such
uncommon cases, who are often misdiagnosed as having anorexia
nervosa or bulimia nervosa or suffering from other anxiety disor-
ders (like OCD or GAD).
Methods A comprehensive mental state examination was con-
ducted including a diagnostic clarification interview. She was
followed up by the mental health team on a regular basis with
support and also providing appropriate psychotherapy.
Discussion Ms. A.M. refused medications and only agreed to
non-pharmacological treatment. She was therefore commenced
on once weekly psychotherapy (CBT), which she undertook for
a period of 4 months. She showed good response to the psy-
chotherapy with significant attenuation of her core symptoms,
although she still continued to exhibit some avoidance behav-
iors.
Conclusions This particular patient showcases a relatively
uncommon and oftenmisdiagnosed specific phobia (emetophobia)
