Effect of rheumatoid arthritis on strength, dexterity, coordination and functional status of the hand: the relationship with magnetic resonance imaging findings.

OBJECTIVE: To evaluate the effect of rheumatoid arthritis (RA) on strength, dexterity, coordination and functional status of the hand and to determine the relation with magnetic resonance imaging (MRI) findings. MATERIALS AND METHODS: Thirty eight patients with RA and thirty three controls were included in the study. There were five drop-outs in RA group. Pain was assessed by visual analog scale. Painful and swollen joints of the dominant hand were recorded. Hand deformities of the patients were noted. Hand grip strength and pinch strength of the dominant hand were evaluated. Hand disability was assessed by Duruoz hand index (DHI) and the Purdue pegboard test was used for assessment of coordination and dexterity. MRI of the dominant wrist and hand was performed in RA group. MRI scans were evaluated for synovitis, tenosynovitis, bone erosion and bone edema. RESULTS: Demographic characteristics were similar between groups. While DHI scores were significantly higher (p=0.000), Purdue pegboard test scores were significantly lower in RA group in comparison to control group (p=0.000). Bone edema and synovitis scores were significantly higher in patients with longer disease duration (p=0.025, p=0,006 respectively). There were significant negative correlation between grip strength, pinch strength subgroups and tenosynovitis scores (p=0.001, p=0,001). When the Purdue pegboard scores were lower, tenosynovitis scores were significantly higher (p=0.019, p=0,013, p=0,043). There was a significant positive correlation between DHI score and tenosynovitis score (p=0.003). CONCLUSION: This study showed that RA has significant negative impact on hand function and dexterity and the parameters used in the evaluation of hand function are mainly associated with tenosynovitis scores. Since tenosynovitis is a common pathology in RA, MRI can be used as a supportive method in early diagnosis of tenosynovitis and may be useful in identification of patients requiring aggressive treatment.

Temperament and Character Profile in Failed Back Surgery Syndrome: A Cross-Sectional Clinical Study.

AIM: Some psychometric properties may predict the development of failed back surgery syndrome (FBSS). The aim of this study was to determine the pain, disability, and depression severity in patients diagnosed with FBSS, and to determine the temperament and character subgroups in comparison with control group. MATERIAL AND METHODS: Thirty-eight patients diagnosed with FBSS, and 35 patients with favourable outcome after lumbar spinal surgery were included to the study. Pain intensity, disability, depression scores, temperament and character profile were determined by the visual analogue scale (VAS), Roland Morris Disability Index, Beck Depression Inventory, and Temperament and Character Inventory. RESULTS: Pain intensity, disability, and depression scores were higher in the FBSS group (p < 0.001). There were no significant differences between temperament and character subgroups between study groups except one of the temperament subgroup, reward dependence (p=0.05). There was a negative correlation between self-directedness and leg pain severity in the FBSS group (p=0.01, r=-0.400). CONCLUSION: No significant differences were found between the FBSS and control groups with respect to temperament and character profile but FBSS was the cause of severe pain, disability, and higher depression scores. This group of patients must therefore be evaluated psychiatrically and should also be subjected to a clinical examination, and they should be managed using a multidisciplinary approach.

The role of neutrophil lymphocyte ratio to leverage the differential diagnosis of familial Mediterranean fever attack and acute appendicitis.

BACKGROUND/AIMS: Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by attacks of fever and diffuse abdominal pain. The primary concern with this presentation is to distinguish it from acute appendicitis promptly. Thus, we aimed to evaluate the role of neutrophil lymphocyte ratio (NLR) to leverage the differential diagnosis of acute FMF attack with histologically proven appendicitis. METHODS: Twenty-three patients with histologically confirmed acute appendicitis and 88 patients with acute attack of FMF were included in the study. NLR, C-reactive protein and other hematologic parameters were compared between the groups. RESULTS: Neutrophil to lymphocyte ratio was significantly higher in patients with acute appendicitis compared to the FMF attack group (8.24 ± 6.31 vs. 4.16 ± 2.44, p = 0.007). The performance of NLR in diagnosing acute appendicitis with receiver operating characteristic analysis with a cut-off value of 4.03 were; 78% sensitivity, 62% specificity, and area under the curve 0.760 (95% confidence interval, 0.655 to 0.8655; p < 0.001). CONCLUSIONS: This study showed that NLR, the simple and readily available inflammatory marker may have a useful role in distinguishing acute FMF attack from acute appendicitis.
