Rheumatoid arthritis is a complex disease, which produces articular symptoms and damage, leading to disability. The aim of the study was the estimate frequency comorbidity, functional ability of patients with rheumatoid arthritis.This study included 60 patients (48 female and 12 male) with rheumatoid arthritis, mean age 53,92±7,06. Anatomical stage and functional class were analyzed according to Steinbrocker`s criteria. Functional disability was perfo-rmed using health assessment questionnaire (HAQ) score. Comorbidity was observed in 36 (60%) of patients (33 female and 3 male). Hypertension were found in 19 (31,67%) of patients, whereas 8 (13,33%) of patients had diabetes. It was established that 7(11,67%) of patients suffered osteoarthritis. The median HAQ score was 1,25±0,70. Poorer functional status was observed in 40% of the patients with comorbidity (HAQ score ≥2), than in the group of patients without comorbidity (21,67 %). The results of the study are showing large frequency coexisting disease in patients with rheumatoid arthritis. The frequency of hypertension and diabetes was greater comparing to general population. The patients with rheumatoid arthritis show harder anatomical stage and comorbidity and greater functional disability, as compared to the patients without coexisting disease.

High frequency of appearance and use of expensive diagnostic and therapeutic methods makes lumbar radiculopathy the most expensive benign disease. The aim of the study was evaluation of types psychological reactions in surgically treated patients with chronic lumbar radiculopathy. Matherial and methods: We examined 50 surgically treated patients who had low back pain. The patients were multidisciplinary examined and treated on Medical Rehabilitation Clinic in Novi Sad. The Minnesota Multiphasic Personal Inventory (MMPI) was used to determine the personality profiles. Patients were tested after rehabilitation treatment. Results of the exploring showed the normal profile of personality in 70 % of patients and pathological profile in 30 % ( hypochondria in 8, hysteria in 5 patients and depression in 2 patients). All groups showed improvement in functional limitation during the rehabilitation treatment. Severity and length of pain after rehabilitation treatment is bigger in the group of patients with pathological profile of personality (p<0,005). Psychological factors may play an important role in the onset, severity, exacerbation, or maintenance of this type of chronic pain. Screening surgically treated patients with chronic lumbar radiculopathy with MMPI may be effective in identifying psychopathology
