Cervicobrachial syndrome--work and disability.

The subjects in the study were 114 persons receiving a disability pension or referred for disability assessment. They were placed in two groups of 57 persons each, one with marked cervicobrachial syndrome and the other without. The latter group was chosen by the method of equivalent pairs with regard to sex and age. All subjects underwent a clinical examination and a standardized questionnaire was completed. The questionnaire pertained to the state of health, focussing on the amount and type of physical burdening at the workplace and on activities outside the workplace. Sixty-five percent of the subjects were aged from 51 to 60 years. A statistically significant difference was established between earlier occupation and cervicobrachial syndrome. Cervicobrachial syndrome was found in 31.6% of unskilled workers and 12.3% of the controls (P < 0.05). A forced body posture during work was recorded in 74% of the subjects with the syndrome and in 50% of the control subjects (P < 0.05). Repetitive movements at work were reported by a large number of subjects with cervicobrachial syndrome (71.9:49.1%; P < 0.05) who also claimed to strain the arms (84.2:61.4%; P < 0.05) and burden the cervical spine (68.5:40.4%; P < 0.05) during household activities to a significantly greater extent than the controls. A possible preventive approach to the occurrence and progression of cervicobrachial syndrome is discussed.     

Changes in the anterior segment of the eye in workers in the coke manufacturing industry

An investigation carried out of eye disorders in workers employed in the manufacture of coke demonstrated a high percentage of changes in the anterior segment of the eye. Registered symptoms such as conjunctival hyperemia, pinguecula, pigmentation and conjunctivitis were most probably connected with specific work and exposure to coal dust and irritants. In workers exposed for less than two years there were no changes in lacrimal secretion. In those working for 2-7 years excessive hypersecretion dominated, and after a longer period of exposure the majority of workers had hyposecretion.     

Countertransference and empathic problems in therapists/helpers working with psychotraumatized persons

Countertransference in therapists working with patients with posttraumatic stress disorder (PTSD) differs from countertransference in other psychotherapeutical settings. In this article we discuss the specificities of counter- transference in treating PTSD patients and its relation to empathy. The most difficult countertransference problems occur in treating multiply traumatized patients. Countertransference may occur towards an event (e.g., war), patients who have killed people, as well as to colleagues who avoid treating PTSD patients, or towards a supervisor who avoids, either directly or indirectly, supervision of therapists working with PTSD patients. Our recommendation for the prevention of problems in treating PTSD patients include : 1) careful selection of the therapist or helper, both in the personality structure and training; 2) prevention by debriefing and team work and peer supervision; and 3) education - theoretical, practical, and therapeutical.     

Endothelial nitric oxide synthase gene polymorphisms and prostate cancer risk in Serbian population

Genome-wide association studies (GWAS) have identified over 46 SNPs associated with human prostate cancer (PCa). Some studies have shown correlation of the nitric oxide synthase (NOS) NOS3 gene polymorphisms with the risk and/or progression of PCa. This study aimed to evaluate the association of NOS3 gene polymorphisms (−786T>C, −764A>G, −714G>T, −690C>T, −649G>A and 894G>T) with PCa risk and progression. 150 patients with PCa, 150 patients with BPH and 100 age-matched healthy controls were recruited in this study. Genotyping of promoter polymorphisms was performed by bi-directional DNA sequencing, and for 894G>T by RFLP analysis. There was no significant association between the alleles and genotypes of these genetic variants and PCa risk. For −786T>C polymorphism, we found that C allele is associated with absence of metastases, assuming dominant genetic model (P = 0.049; OR, 0.50; 95% CI, 0.25–1.00). It was found that, compared with NOS3 −690C>T variant CC genotype, CT and TT genotypes confer decreased risk of developing metastases (dominant model, P = 0.015, OR, 0.24; 95% CI, 0.07–0.88) and show association with low clinical tumour stage, compared with stages T₃ and T₄ (dominant model, P = 0.046, OR, 0.20; 95% CI, 0.04–1.02). Genetic variants −764A>G, −714G>T, −649G>A were not detected in our study group. There is evidence of an inverse correlation of the NOS3 894G>T minor allele with high serum PSA (>20 ng/ml) (dominant model, P = 0.013, OR, 0.37; 95% CI, 0.17–0.82). Our results suggest that NOS3 gene polymorphisms are genetic susceptibility factors for the progression of PCa and patient outcome.     

The Influence of Etiologic Factors on Clinical Outcome in Patients with Peptic Ulcer Bleeding

Background

Peptic ulcer bleeding remains an important cause of morbidity and mortality.

Aim

The aim of this study was to evaluate the prevalence of non-steroidal anti-inflammatory drugs (NSAID) use, Helicobacter pylori infection and non-H. pylori?Cnon-NSAIDs causes of peptic ulcer bleeding and to identify the predictive factors influencing the rebleeding rate and in-hospital mortality in patients with bleeding peptic ulcer.

Methods

A total of 1,530 patients with endoscopically confirmed peptic ulcer bleeding were evaluated consecutively between January 2005 and December 2009. The 30-day mortality and clinical outcome were related to patient??s demographic data, endoscopic and clinical characteristics.

Results

The age-standardized 1-year cumulative incidence for peptic ulcer bleeding was 40.4 cases/100,000 people. The proportion of patients over 65?years increased from 45.7?% in 2005 to 61.4?% in 2009 (p?=?0.007). Overall 30-day mortality rate was 4.6?%, not significantly different for conservatively and surgically treated patients (4.9 vs. 4.1?%, p?=?0.87). Mortality was significantly higher in patients over 65?years of age and those with in-hospital bleeding recurrence. Patients with non-H. pylori?Cnon-NSAID idiopathic ulcers had significantly higher 30-day mortality rate than those with H. pylori ulcers and NSAID?CH. pylori ulcers (7.1 vs. 0 vs. 0.8?%, p?=?0.001 and p?=?0.007, respectively). There was no statistically significant difference between patients with NSAID ulcers and non-H. pylori?Cnon-NSAID idiopathic ulcers in terms of 30-day mortality rate (5.3 vs. 7.1?%, p?=?0.445).

Conclusion

The incidence of peptic ulcer bleeding has not changed over a 5-year observational period. The overall 30-day mortality was positively correlated to older age, underlying comorbid illnesses, in-hospital bleeding recurrence and the absence of H. pylori infection.
