Editorial

It has been proven that the jaw rehabilitation not only has a crucial role in treatment of both trismus and mandibular hypomobility but also in the rehabilitation of surgical conditions of the temporomandibular joint and the jaw.(1) Today, the commercially available jaw motion rehabilitation systems are specifically designed to treat these conditions.(2) These systems utilize repetitive passive motion and stretching to restore mobility and flexibility of the jaw musculature, associated joints and connective tissues. Major advantages of these systems are that they reduce patients' anxiety by allowing them to control the extent and length of each stretching and provide passive motion for effective jaw rehabilitation therapy allowing patients to perform their necessary therapy while continuing in their daily life.(3) However, these systems are very expensive and mostly unavailable in our country. So, a new alternative jaw motion rehabilitation device 'The Okbite' was developed recently in our hospital (Fig. 1). It is simply adapted from the commercially available nasal specula. The blades of the specula are cut distally and metal bite pads are attached to these sites. The lower bite pad was placed posteriorly and curved anatomically. This device can be produced in a custom-made form according the occlusal pattern and the size of the mandible of the patient. The metal bite pads are covered with plaster bandage by the patient for a soft bite. In our practice, we used this device for the rehabilitation of total temporomandibular joint prosthesis, temporomandibular gap arthroplasties and temporomandibular joint disorders with great success. It costs nearly 1/50 of the commercially available jaw motion rehabilitation systems with almost equal outcomes of pain relief and total mouth opening. The major disadvantage of this system is that it can mimic the anatomical motion pattern of the mandible to a limited extend. We propose the application of this Okbite system, which provides jaw rehabilitation in such conditions.     

Oral complaints of denture-wearing elderly people living in two nursing homes in istanbul, Turkey

Aim: The aim of this study was to observe and determine oral complaints of people aged 55 years or older, living in two nursing homes in Istanbul, Turkey, and their satisfaction with their complete or partial dentures by means of a simple questionnaire. Methods: Two old peoplea??s homes (one public and one private) in the district of Uskudar in Istanbul agreed to take part in this study. All residents who were available were invited to answer a piloted nine-point questionnaire with questions on age, gender, physical problems, eating, and communication, aesthetic denture wearing and psychological problems. The questions were asked in person by one investigator. The resulting data were entered into SPSS version 15. Results: Out of a total of 210 residents, 130 (61.9%) took part in the study, of whom 53% (n=71) of residents were living in the private nursing home and 60% (n=81) were female. One hundred and five (80%) were denture wearers. More than half of the residents (59%, n=79) were over 75 years old. Problems were mostly seen in older ages, especially those over 75 years old, over 60% of whom reported problems for all the variables listed in the questionnaire. Women were more aware of halitosis than men. Conclusions: The results of this study confirm those of previous studies and suggest that elderly people with dentures, and particularly complete dentures, frequently complain of a wide range of problems including: eating, social interaction and communication and these problems have a detrimental influence on their quality of life.     

Higher expression of the novel gene upregulated gene 4 in two acute lymphoblastic leukemia patients with poor prednisolone response

Elucidation of the molecular mechanisms of leukemogenesis is important for a better understanding of the prognosis of acute lymphoblastic leukemia (ALL). Studies have shown that the expression of upregulated gene 4 (URG4), which promotes cell growth and survival, is increased in different types of carcinomas including hepatocellular carcinoma, gastric cancer and osteosarcoma. Similarly, higher expression of URG4 and cyclin D1 gene might promote proliferation of the blast cells by causing escape from the G1 checkpoint and entry into the S phase. This study reports the high expression level of URG4 in 2 high-risk ALL patients for the first time in the literature. In conclusion, the higher expression of URG4 in our 2 patients suggests that URG4 might be involved in leukemogenesis. Future studies with a large number of high-risk ALL patients and cell culture studies are needed to demonstrate the exact role of URG4 in leukemogenesis.     

Validation of the Turkish version of the fatigue severity scale in patients with fibromyalgia

The aim of the study was to investigate the validity and reliability of the Turkish version of the fatigue severity scale (FSS) in fibromyalgia (FM) patients. Sixty-one FM patients and 54 healthy controls were evaluated using the Turkish version of the FSS. Reliability was investigated using test–retest reliability and internal consistency. Concurrent validity was evaluated between the FSS score and the VAS fatigue. Convergent validity was assessed by comparing the FSS score with the scores of VAS pain, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Fibromyalgia Impact Questionnaire (FIQ). Spearman’s rank correlation coefficient was used to evaluate validity. Test–retest reliability and internal consistency of the FSS were excellent in FM patients (ICC: 0.94, Cronbach’s alpha coefficient: 0.85) and in the healthy controls (ICC: 0.90, Cronbach’s alpha coefficient: 0.91). For the concurrent validity, the correlation between the FSS and VAS fatigue was very good in FM group (r: 0.63, P: 0.000) and in the healthy controls (r: 0.94, P: 0.000). For the convergent validity, correlations between the FSS and BDI, BAI, FIQ, pain intensity were moderate to good in both groups (P: 0.000). The Turkish version of the FSS has been proved to be valid and reliable to detect severity of fatigue in FM patients. We recommend the use of it in clinical practice.     

Recipient splenic artery utilization for arterial re-anastomosis in living donor liver transplantation: single-center experience

Thrombosis of recipient hepatic artery is a life threatening complication for liver transplantation. The etiology of hepatic arterial thrombosis is multi-factorial and can be caused by intimal dissection, poor surgical technique and coagulopathies. The patency of hepatic arterial flow is very important for both graft survival and patient survival. Intraoperative diagnosis of inadequate hepatic arterial flow found with Doppler ultrasonography is essential in order to achieve good results after liver transplantation. Urgent re-anastomosis is necessary when the arterial blood flow is insufficient. We performed 317 living donor liver transplantations from July 2004 to July 2011. We used recipient splenic artery for hepatic artery reconstruction in six patients. These six patients were included in this study. Using the recipient splenic artery is a simple, safe and practical alternative for hepatic artery re-anastomosis in living donor liver transplantations.     

The efficacy of phonophoresis on electrophysiological studies of the patients with carpal tunnel syndrome

To investigate the efficacy of phonophoresis with nonsteroid anti-inflammatory drugs (P-NSAID) and corticosteroids (P-CS) in the treatment for carpal tunnel syndrome (CTS) and to compare the efficacy of phonophoresis with local CS injection (LCSI) and splinting with a 3-month follow-up. 84 hands of 51 patients with CTS were treated by applying LCSI, P-CS, P-NSAID, and wrist splinting. Electrophysiological studies, grip strength, hand dexterity, and sensory recovery of the first three digits were assessed. Duru?z hand index (DHI) was used to assess the functional hand disability. For clinical evaluation, we used Phalen and Tinnel signs. Pain intensity was evaluated by visual analog scale. The LCIS group showed a significant improvement in pain relief and DHI, but this group had significant deterioration in the results of monofilament and pegboard tests. The P-CS group showed improvement in sensory nerve conduction velocity, distal latency, grip strength, and DHI parameters. There was a significant improvement in grip strength, pegboard test, and pain intensity in the P-NSAID group. There was improvement only in pain intensity in the splinting group. We identified marked improvement in the electrophysiological studies in the P-CS group. Splinting had no effect on hand functions, disability, and electrophysiological studies.     

Infliximab attenuates activated charcoal and polyethylene glycol aspiration-induced lung injury in rats

Aspiration is a serious complication of gastrointestinal (GI) decontamination procedure. Studies have shown that tumor necrosis factor-α (TNF-α) blockers have beneficial effects on lung injury. Therefore, the authors investigated the attenuation by infliximab (INF) on activated charcoal (AC)- and polyethylene glycol (PEG)-induced lung injury in rat model. Forty-two male Sprague-Dawley rats were allotted into 1 of 6 groups: saline (NS), activated charcoal (AC), polyethylene glycol (PEG), NS+INF treated, AC+INF treated, and PEG+INF treated. All materials were aspirated into the lungs at a volume of 1 mL/kg. Before aspiration, the rats were injected subcutaneously with INF. Seven days later, both lungs and serum specimens in all groups were evaluated histopathologically, immunohistochemically, and biochemically. Following aspiration of AC and PEG, evident histopathological changes were assigned in the lung tissue that were associated with increased expression of inducible nitric oxide synthase (iNOS), increased serum levels of oxidative stress markers (malondialdehyde [MDA], surfactant protein-D [SP-D], TNF-α), and decreased antioxidant enzyme (glutathione peroxidase [GSH-Px]) activities. INF treatment significantly decreased the elevated serum MDA and TNF-α levels and increased serum GSH-Px levels. Furthermore, the current results show that there is a significant reduction in the activity of iNOS in lung tissue and increased serum SP-D levels of AC and PEG aspiration-induced lung injury with INF treatment. These findings suggest that INF attenuates lung inflammation and prevents GI decontamination agent-induced lung injury in rats.
