Smaller right hippocampus in war veterans with posttraumatic stress disorder

Chronic stress can putatively cause damage in the human hippocampus, but evidence of damage has not been consistently shown in studies on hippocampal morphology in posttraumatic stress disorder (PTSD). We compared hippocampal volumes in PTSD patients and normal subjects. Using a 3D T1-weighted GRE magnetic resonance imaging sequence, we measured hippocampal volumes in 15 war veterans with combat-related chronic PTSD and 15 case-matched normal controls. Although war veterans, our PTSD subjects were not professional soldiers and were mobilized shortly before they were exposed to a very specific combat-related trauma over a 3-day period. In our study, the period between traumatic exposure and imaging was considerably shorter, on average, 9 years, compared with at least two decades in previous studies on subjects with combat-related PTSD. Moreover, our subjects were free of any comorbidity, treatment or medication. The right hippocampus was significantly smaller in PTSD subjects than in healthy controls. The left hippocampus was also smaller in PTSD subjects than in controls, but the difference was not significant. In all PTSD subjects, the right hippocampus was smaller than the left (on average, 7.88%). Our results show smaller volume of the right hippocampus in PTSD patients than in normal subjects.

Quality of life in Croatian Homeland war (1991- 1995) veterans who suffer from post-traumatic stress disorder and chronic pain

BackgroundThe aim of this study was to investigate the quality of life in Croatian homeland war veterans who suffer from post-traumatic stress disorder and chronic low back pain (LBP).MethodsA total of 369 participants were included, classified in four study groups: those with post-traumatic stress disorder (PTSD; N = 59), those with both PTSD and lower back pain (PTSD+LBP; N = 80), those with isolated LBP (N = 95) and controls (N = 135). WHOQOL-BREF survey was used in the estimation of quality of life. The data were analysed using statistical methods and hierarchical clustering.ResultsThe results indicated a general pattern of lowering quality of life in participants with both psychological (PTSD) and physical (LBP) burden. The average overall quality of life was 2.82 ± 1.14 for the PTSD+LBP group, 3.29 ± 1.28 for the PTSD group, 4.04 ± 1.25 for the LBP group and 4.48 ± 0.80 for the controls (notably, all the pair-wise comparisons were significantly different at the level of P < 0.001, except for the pair LBP-controls, which was insignificant). This result indicated that quality of life was reduced for 9.9% in patients with LBP, 26.6% in patients with PTSD and 37.1% in PTSD+LBP, suggesting strong synergistic effect of PTSD and LBP. The analysis also identified several clusters of participants with different pattern of quality of life related outcomes, reflecting the complex nature of this indicator.ConclusionsThe results of this study reiterate strong impact of PTSD on quality of life, which is additionally reduced if the patient also suffers from LBP. PTSD remains a substantial problem in Croatia, nearly two decades after the beginning of the 1991-1996 Homeland war.

Person-centered medical interview

Abstract We are witnessing an unprecedented development of medical science and personalized medicine. However, technological superiority must not make us lose sight of the physical, psychological, social, and spiritual totality of the patient. The core of the medical profession has always been and will be the relationship between the health professional and the person seeking assistance. However, the traditional relationship between the physician and the patient has changed and is greatly impacted by huge social, philosophical, economic, and scientific developments. It is important to develop and promote the culture of health instead of the culture of illness through a patient-doctor collaborative partnership, as well as partnership among professionals. Person-centered medical interview is an important bridge between personalized and person-centered medicine.

Psychometric properties and factor structure of the Temperament and Character Inventory-Revised (TCI-R) in a Croatian psychiatric outpatient sample

OBJECTIVE The goal of this study was to investigate psychometric properties and factorial structure of the Croatian adaptation of the Temperament and Character Inventory-Revised (TCI-R) in a sample of psychiatric outpatients (n=328). METHOD The participants filled out the TCI-R, as well as self-report measures of the Big-Five personality traits (IPIP-50), trait impulsivity (BIS-11), depression (BDI-II), suicidality (SBQ-R), and life satisfaction (SWLS). We explored the internal consistency of 7 domains and 29 subscales and compared it with the Croatian version of the original TCI used in prior studies. Principal component analysis with promax rotation was conducted on temperament and character subscales separately, while concurrent validity was examined through the TCI-Rs relations with the abovementioned psychological measures. RESULTS The TCI-R scales showed adequate internal consistencies, with Cronbachs alpha values ranging from 0.77 to 0.93. The internal consistency showed to be higher in comparison with the Croatian version of the original TCI. The postulated four-factor structure of temperament and the three-factor structure of character were confirmed. The meaningful associations with other measures supported the concurrent validity of the TCI-R. CONCLUSION The Croatian adaptation of the TCI-R exhibited satisfactory reliability and validity in a sample of psychiatric outpatients. These findings support the use of the TCI-R in Croatian clinical settings over its predecessor (TCI).

Is experimentally induced pain associated with socioeconomic status? Do poor people hurt more?

Background The association of pain and socioeconomic status is widely reported, yet much less clearly understood. The aim of this study was to investigate the association of experimentally induced pain threshold and tolerance with socioeconomic status. Material/Methods The study sample consisted of 319 adult subjects from the population of the island of Vis, Croatia, which was previously shown to have a high level of social homogeneity. A manual dolorimeter was used to measure mechanical pressure pain threshold (least stimulus intensity) and pain tolerance (maximum tolerance stimulus intensity) on both hands. Pain tolerance interval was defined as the difference between pain tolerance and threshold. Years of schooling and material status were used as socioeconomic estimates. Results Both of the socioeconomic estimates were significantly correlated with pain threshold, tolerance, and tolerance interval (P<0.001). The mixed modeling analysis, controlled for the effects of age, gender, and 4 psychological variables, indicated that education was not a significant predictor in any of the 3 models. However, lower material status was significantly associated with lower pain tolerance (P=0.038) and narrower pain tolerance interval (P=0.032), but not with pain threshold (P=0.506). The overall percentages of explained variance were lower in the tolerance interval model (20.2%) than in pain tolerance (23.1%) and threshold (33.1%), suggesting the increasing share of other confounding variables in pain tolerance and even more so in tolerance interval model. Conclusions These results suggest a significant association between experimentally induced pain tolerance and tolerance interval with material status, suggesting that poor people indeed do hurt more.

The founding of the Centre for Palliative Medicine, Medical Ethics and Communication Skills: a new step toward the development of patient-oriented medicine in Croatia.

One of the main conceptual changes in the 20th century medicine is the inclusion of social dimension. The “golden era” of Parson’s medical model (1), which uses the “active-passive” dichotomy to describe the positions and expectations of physicians and patients, is over. Physicians’ supremacy has slowly and systematically been challenged by the emergence of third party stakeholders, development of new media sources, strengthening of the civil society, and democratization of information, which all have contributed to the development of the patients’ active role in the healing processes (2). The rise of medical consumerism has stimulated the medical authorities to react with a new ideological policy: the patient-oriented medicine, insisting on the partnership in the diagnostic and therapeutic processes, and viewing the patient as a person with biological, psychological, social, and spiritual needs (2).
