PDCD4 and MIR-21 are promising biomarkers in the follow-up of OED in liquid biopsies.

This research aims to examine the impact of programmed cell death 4 (PDCD4), microRNA-21 (miR-21) and microRNA-208a (miR-208a) transcripts, and protein levels on oral epithelial dysplasia (OED) development in oral squamous cell carcinoma (OSCC). METHODS: The research investigation involved the collection of saliva, blood, and tissue samples from a total of 20 patients diagnosed with OSCC, 15 patients diagnosed with OED, and 15 healthy individuals. PDCD4, miR-21, and miR-208a expression was performed by quantitative reverse transcription polymerase chain reaction (qRT-PCR). PDCD4 protein levels were assessed using enzyme-linked immunosorbent assay (ELISA) in both saliva and blood samples. For statistical analysis, the Kruskal-Wallis test and the Spearmen rank test were utilised. RESULTS: PDCD4 expression levels were considerably lower in patients with OSCC and OED (p < 0.05) in three biological samples. In contrast, miR-21 expression was higher in OED and OSCC patients. Patients with low PDCD4 mRNA levels and strong miR-21 expression had a significant connection (p < 0.05) with tumor size and depth. CONCLUSIONS: Examining PDCD4 and miR-21 transcript levels may help detect the transition from OED to OSCC. This work suggests that PDCD4 and miR-21 expression levels in liquid biopsies may be biomarkers for OED monitoring in the future.

The Cytokines-Directed Roles of Spirulina for Radioprotection of Lacrimal Gland.

PURPOSE: To evaluate the radioprotective effect of spirulina (SP) on the lacrimal glands after RAI treatment. METHODS: A total of 30 rats were separated into control, RAI and SP group. The radioprotective effect of SP on lacrimal glands was evaluated with histopathological and cytopathological analysis. Lacrimal glands were analyzed for tumor necrosis factor alpha (TNF-α), interleukin-2 (IL-2), IL-4, IL-6, IL-10, nuclear factor-kappa B (NF-κB), total oxidant status (TOS) and total antioxidant capacity (TAC) levels. RESULTS: RAI increased TNF-α (p = .001), IL-6 (p = .018), and NF-κB levels (p < .0005). Following the administration of SP, TNF-α (p < .0005), IL-4 (p = .026), and IL-6 (p = .006) levels decreased. RAI decreased the TAC levels (p = .001), and co-administration of SP increased the TAC level, but was not statistically significant. SP decreased the TOS level after RAI (p = .022)                . CONCLUSIONS: SP protects lacrimal glands from RAI-induced damage.

A Rare Case of Flexor Tenosynovitis Due to Tuberculosis in Hand and Wrist: a Case Report.

Tuberculosis (TB) is still a worldwide problem. We present a case of flexor tenosynovitis due to tuberculosis in the hand and wrist. A 42-year-old man presented to the outpatient clinic with a 2-year history of a slowly growing mass over the volar aspect of the left wrist. His MRI showed multiple rice bodies in the wrist and hand. An open biopsy was performed. Pathology specimens showed granulomatous lesions with central necrosis. The purified protein derivative (PPD) test was positive. In this case, granulomatous lesions with central necrosis, rice bodies, and positive PPD test confirmed the diagnosis of TB in the wrist and hand. There was no other concurrent evidence of TB elsewhere. Antituberculosis chemotherapy was commenced. Tuberculous tenosynovitis of the wrist and hand is very rare. The tuberculous tenosynovitis should be kept in mind as an infectious agent when patients are presenting with atypical clinical. Key words: tuberculosis, rice bodies, flexor tenosynovitis, wrist, hand.

Comparison of the Efficacy of Different Concentrations of Diclofenac Sodium Phonophoresis (1.16% vs 2.32%) in Patients with Knee Osteoarthritis: a Randomized Double-Blind Controlled Trial.

PURPOSE OF THE STUDY The objective of the present study is to compare the efficacy of two different concentrations of diclofenac sodium phonophoresis (DSPH) (1.16% vs 2.32%) in patients with knee osteoarthritis (OA). MATERIAL AND METHODS A randomized, double-blind, controlled design was applied. Ninety patients (mean age± SD, 59.98 ± 8.89 years) who had Kellgren-Lawrence (K-L) grades II to III knee OA were randomly allocated into three groups; 1.16% DSPH, 2.32% DSPH, TUS (30 in each group). Each patient was treated five sessions per week for two weeks. A 100-mm visual analogue scale (VAS) for usual pain and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were evaluated before and after treatment in all groups. RESULTS The VAS pain and WOMAC scores were significantly improved after treatment in all groups (p < 0.05). The 2.32% DSPH showed more significant effects than the 1.16% DSPH, both in improving WOMAC- pain and physical function scores (p = 0.020, p = 0.008) and reducing the VAS pain measure, although it did not reach the level of significance (p = 0.077). The 2.32% DSPH was superior to the TUS, both in reducing the VAS pain measure (p < 0.001) and in improving WOMAC-pain, stiffness, physical function and total scores (p = 0.022, p = 0.016, p < 0.001, p < 0.001 respectively). 1.16% DSPH significantly reduced stiffness and physical function scores compared with TUS (p = 0.042, p = 0.047). CONCLUSIONS DSPH and TUS are effective treatments for knee OA. Our results indicated that 2.32% DSPH produces additional benefits to functional improvement and pain reduction compared with 1.16% DSPH in K-L grades II to III knee OA. Key words: diclofenac sodium, knee osteoarthritis, phonophoresis, therapeutic ultrasound, topical formulation.

Salivary irisin: potential inflammatory biomarker in recurrent apthous stomatitis patients.

OBJECTIVE: Recurrent Aphthous Stomatitis (RAS) is the most common inflammatory condition of the oral mucosa characterised by recurrent onset of single or multiple painful ulcers mainly affecting the nonkeratinized oral mucosa. RAS mostly occurs in healthy individuals with no associated systemic diseases. Irisin is a newly identified adipomyokine and research has revealed that it has anti-inflammatory effects. The aim of this study was to investigate the significance of salivary irisin levels in patients with recurrent apthous stomatitis (RAS). PATIENTS AND METHODS: In this investigation, 80 individuals were evaluated. The patient group included 30 patients diagnosed with RAS and each control group consisted of 25 smoker and non-smoker healthy individuals. Saliva samples were collected and salivary irisin, interleukin-2 (IL-2) and interferon-É£ (IF-É£) levels were determined using enzyme-linked immunosorbent assay (ELISA). RESULTS: IL-2 and IF-É£ levels in RAS patients were significantly higher than control smoker and non-smoker groups (p=0.0001, p=0.0001, respectively). Irisin level was higher in RAS patients than smoker controls and non-smoker controls. The level of irisin was found as sensitive and specific as IL-2 and more sensitive and specific than IF-É£. The salivary levels of pro-inflammatory cytokines IL-2 and IF-É£ and irisin were higher in RAS group compared to controls. CONCLUSIONS: This is the first report evaluating the irisin an adipo-myokine as an inflammatory biomarker in RAS.

Evaluation of Methylation Profiles of An Epidermal Growth Factor Receptor Gene in a Head and Neck Squamous Cell Carcinoma Patient Group.

Upregulation of the epidermal growth factor receptor (EGFR) gene has shown an important impact on the development of head and neck cancers due to its important regulation role on multiple cell signaling pathways. The aim of this study was to investigate the methylation pattern of the promoter region of the EGFR gene between head and neck squamous cell carcinoma (HNSCC) patients and a control group. Forty-seven unrelated HNSCC patients, clinically diagnosed at the Department of Otorhinolaryngology, Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkey, and 48 unrelated healthy volunteers from different geographic regions of Turkey, were included in this study. Methylation status of the promoter region of the EGFR gene was detected by methylation-specific-polymerase chain reaction (MS-PCR). The correlation between EGFR gene promoter methylation profiles and clinical characteristics were examined using the χ2 test. Methylation was observed in 79.0% of HNSCC patients, whereas this ratio was 90.0% in healthy individuals. The results show that promoter region methylation of the EGFR gene was not associated with HNSCC development in the studied Turkish patient group. In addition, the methylation status of the EGFR gene promoter was not found to be related to age, gender or tumor stage.

RELIABILITY OF THE CORTICOTROPIN RELEASING HORMONE STIMULATION TEST FOR DIFFERENTIATING BETWEEN ACTH DEPENDENT AND INDEPENDENT CUSHING SYNDROME.

CONTEXT: It is a challenge to determine the origin of Cushing syndrome (CS), especially in patients with low-normal adrenocorticotropic hormone (ACTH) concentrations. OBJECTIVE: To evaluate the reliability of the corticotropin-releasing hormone (CRH) stimulation test in patients with CS whose origin of disease was not clearly identified using ACTH values, the high-dose dexamethasone suppression test (HDDST), and imaging in a single tertiary referral center. DESIGN AND METHODS: Twenty-one patients with CS who were admitted to the endocrinology-metabolism clinic between 2004 and 2016 whose ACTH concentrations were 5-20 pg/mL and needed CRH stimulation test were retrospectively assessed. RESULTS: Nine out of 21 patients were diagnosed as having Cushing's disease (CD) and 12/21 had adrenal CS. The CRH stimulation test had a sensitivity and specificity of 100% and 8%, and positive and negative predictive values of 100% and 45% according to the current diagnostic criteria, respectively. An increase in ACTH ≥115% at 15 minutes and cortisol ≥86% at 60 minutes after CRH were associated with the highest likelihood ratio. The sensitivity and specificity of ACTH was 67% and 83% (AUC=0.75±0.12, 95% CI: [0.5-0.9]; p=0.03), and for cortisol it was 75% and 78% (AUC=0.71±0.15, 95% CI: [0.5-0.9]; p=0.03). Cortisol suppression of more than 64% from basal level in the HDDST suggested CD with the highest likelihood ratio. When these cut-off values were used together, both tests were negative in the patients with CD. CONCLUSION: The CRH stimulation test has low specificity to localize CS in patients with ACTH concentrations of 5-20 pg/mL according to the current diagnostic criteria. Different diagnostic criteria may be used in the CRH stimulation test and also in the HDDST in this group of patients.

Life Quality and Compliance After Transplant: The Case of Turkey.

OBJECTIVE: Chronic renal failure is one of the most significant health problems in Turkey, as it is all over the world, and negatively affects quality of life. The aim of this study is to find factors affecting compliance levels and quality of life of patients undergoing kidney transplant. MATERIALS AND METHODS: The population of the study consisted of 244 patients who underwent kidney transplant. Although the study aimed to cover the entire target population in the sampling selection, it was conducted among 206 patients. The data were collected by face-to-face interview. RESULTS: Of the patients, 92.7% were between 46 and 59 years of age, 54.4% had a living donor transplant, 54.9% had adverse effects, and 2.9% had rejection due to incompatibility. There was a significant relationship between compliance and quality of life; increasing frequency of adverse effects would decrease in direct proportion to compliance, which would, therefore, increase quality of life. All the subscale scores of the 36-Item Short Form Health Survey were found to have an average of 60 and above. The mean of the compliance scale was 48.33 (SD, 3.21), and, with the maximum score at 55, the mean of the group was high. In our country, patients view transplant as a final and definite treatment method. This might be related to fact that the longer the time after transplant, the lower the level of compliance.

Beneficial effects of vitamin E on radioiodine induced gastrointestinal damage: an experimental and pathomorphological study.

OBJECTIVES: The aim of the present study was to investigate the radioprotective effect of vitamin E in the prevention of radioiodine (RAI) induced gastrointestinal damage. METHOD: Twenty-four rats were randomly divided into three groups as follows: Group-1 was untreated control group, Group-2 was orally administered single dose of 111 MBq RAI, and Group-3 was orally administered 111 MBq RAI and 1 mL of oral vitamin E. Vitamin E was started two days before RAI administration and was continued for five days once daily after RAI. Pathomorphological parameters of gastrointestinal tissues (stomach, small intestines and bowels) were measured using Hematoxylin-Eosin and Masson's trichrome staining. RESULTS: Varying degrees of inflammation, edema, ulcer, mucosal degeneration, necrosis and fibrosis were seen in the stomach, small intestine and bowel tissues of the rats in both study groups and not in the control group. The differences were statistically significant between these groups for all parameters (p < 0.05). The histopathological damage in the vitamin E treated group was significantly less than the damage in the RAI only group (p < 0.05 for all pathomorphological parameters). CONCLUSION: The results of this study showed that vitamin E has a radioprotective property with antiinflammatory and antifibrotic effects protecting against gastrointestinal damage caused by radioiodine (Tab. 3, Fig. 3, Ref. 26).

Do CO2 and oxidative stress induce cancer?: a brief study about the evaluation of PON 1, CAT, CA and XO enzyme levels on head and neck cancer patients.

Head and neck cancer (HNC) is one of the most common malignancies in the world. HNC is a group of cancers that starts in the mouth, nose, throat, larynx, sinuses, or salivary glands. According to this section of the body parts; induction of cancer can be associated with CO2 and oxidative stress. The aim of this study is to assess the activities of carbonic anhydrase (CA), catalase (CAT), paraoxonase1 (PON1), and xanthine oxidase (XO) activities in 89 HNC patients and 115 healthy volunteers. Paraoxonase1 activity was found lower in HNC cancer patients. There is no statistically significant difference between patients and controls for catalase, carbonic anhydrase, and xanthine oxidase enzyme levels. According to this results, paraoxonase1 levels could be a candidate as an oxidative marker in HNC patients, but further studies are needed to investigate the other type of cancer related PON1 and the other enzyme levels.

Breast Reduction Using the Superomedial Pedicle- and Septal Perforator-Based Technique: Our Clinical Experience.

BACKGROUND: Adequate tissue removal must be performed for symptom relief following reduction mammoplasty. However, this is not always possible in patients with gigantomastia because the pedicle is planned wider and the breast cannot be sufficiently reduced to prevent compromising the blood supply to the pedicle. To maximize blood circulation to the nipple-areola complex in our patients, the pedicle was planned to include the internal thoracic artery branches coming from both the second and third interspaces and the intercostal artery branches coming from the fourth and fifth intercostal spaces. METHODS: A total of 185 patients underwent reduction mammoplasty with the superomedial pedicle- and septal perforator-based technique. The mean weight of excised tissue was 928.77 g from the right breast and 899.92 g from the left, whereas the mean distance of nipple-areola transfer was 11.52 cm on the right breast and 11.27 cm on the left. RESULTS: Complications developed in 11 patients (5.94%): hematoma occurred in three patients, partial loss of areola and fat necrosis in five patients, and wound dehiscence in three patients. CONCLUSIONS: The pedicle included vessels of both superomedial and septum origin without any disruption in circulation. Consequently, the blood supply of the nipple-areola complex was preserved. Furthermore, in cases where the pedicle was long, intercostal perforators were identified and the pedicle was narrowed thoroughly; thus, the breast was reduced to the desired volume while minimizing the risk of complications.

Metachronous bilateral multifocal nodular oncocytic hyperplasia of the parotid gland.

Multifocal nodular oncocytic hyperplasia (MNOH) is a rare lesion of the parotid gland and bilateral cases are extremely rare. We report the case of a 69-year-old woman who was operated from MNOH 10 years ago and the bilateralism of the case appeared 10 years later making the case metachronous.

The protective effect of melatonin on sperm quality in rat after radioiodine treatment.

This study was designed to investigate the potential radioprotective impact of melatonin on the testicular tissue and sperm quality in rat given radioactive iodine (RAI) therapy. Thirty-six male Wistar albino rats were randomly divided into three groups as untreated control (Group 1); oral radioiodine group (RAI, 111 MBq, administrated rats); and RAI+melatonin group (oral radioiodine and intraperitoneal 12 mg/kg/day melatonin, starting 2 days before and continuing for 1 week after oral RAI administration). Twenty-four hours after the injection of the last melatonin dose, blood samples were taken for hormone analyses and the determination of the total antioxidant capacity. Sperm samples taken from the cauda epididymis were examined for spermatological parameters. Tissue samples taken from the rat testes were stained by TUNEL assay and with haematoxylin-eosin to detect apoptosis and histological alterations. It was demonstrated a significant decrease in epididymal spermatozoa viability and motility in all of the treatment groups, in comparison with the control group (p < .001). A significant decrease was also detected in sperm DNA fragmentation, follicle-stimulating hormone (FSH) level and the index of apoptotic germ cells in the RAI+melatonin group when compared to the radioiodine group. It was concluded that melatonin prevents the adverse affects of RAI on apoptosis and spermatozoa quality.

Investigation of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and mean platelet volume in patients with tinnitus.

OBJECTIVE: This study aimed to evaluate patients with tinnitus in terms of mean platelet volume and platelet distribution width, and to explore neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio, recently reported in the literature as being possible inflammation markers. METHODS: This study comprised 64 tinnitus patients and 64 age-matched healthy controls. Statistical significance level was accepted as p < 0.05. RESULTS: Mean platelet volume (t = 3.245, p = 0.002) and platelet distribution width (Z = 3.945, p < 0.001) were significantly higher in the patient group than the control group. CONCLUSION: The results suggest that a prothrombotic condition might play a role in the pathophysiology of tinnitus.

Melatonin: a hepatoprotective agent against radioiodine toxicity in rats.

OBJECTIVES: The aim of the current study was to investigate the possible radioprotective effects of melatonin against hepatic radioiodine (RAI) toxicity. METHODS: Thirty-six rats were randomly divided into three groups: untreated control (Group 1); oral radioiodine (RAI, 111 MBq) administrated rats (Group 2), and melatonin group (oral RAI and daily intraperitoneal injection of 12 mg/kg melatonin-Group 3). In the third group, melatonin administration was started two days before and continued for five days after RAI administration. Twenty-four hours after the administration of the last dose of melatonin, liver samples were taken for biochemical and histopathological evaluation. RESULTS: Oxidative stress parameters demonstrated that melatonin treatment decreased the tissue malondialdehyde (MDA), advanced the oxidation protein products (AOPP) levels, and increased the total-SH (sulphydryl) levels when compared with RAI group. The differences were statistically significant between these groups for all parameters (p < 0.05). The histopathological damage in the melatonin-treated group was significantly less than the damage in RAI group (p < 0.05 for all pathological parameters). CONCLUSION: The results of this study demonstrated that melatonin reduced the harmful effects of RAI treatment on the liver. Anti-inflammatory and antioxidant activities are likely to be involved in the mechanism underlying the radio-protective effects of melatonin (Tab. 3, Fig. 1, Ref. 30).

Predictive value of neutrophiltolymphocyte ratio in the severity of non-alcoholic fatty liver disease among type 2 diabetes patients.

BACKGROUND: Non-alcoholic fatty liver disease is a progressive inflammatory disease that ultimately results in cirrhosis and liver failure. It is assosiciated with two step hit scenario; the first step is fat accumulationin liver and in the second step inflammation and fibrosis are the major compenents. The incidence of this disease is increasing worldwide, following rising incidences of obesity and diabetes mellitus. AIM: The aim of this study is to analyze the relationship between non-alcoholic fatty liver disease andseverity and neutrophil-to-lymphocyte ratio among the patients having type 2 diabetes mellitus. METHODS: This study involved 143 patients with type 2 diabetes who were placed into four groups (grade 0, 1, 2, 3) based on steatosis level due to blinded ultrasonographic evaluation. Biochemical parameters and counts of total white blood cells, neutrophils, and lymphocytes were determined. Neutrophil-to-lymphocyte ratio was compared across the four patient groups. RESULTS: Levels of hemoglobin A1c, creatinine, alanine aminotransferase, high-density lipoprotein cholesterol and triglycerides were significantly different between the four patient groups (ANOVA p-values: p <0.001, p=0.011, p=0.002, p=0.034, p=0.002, respectively). Counts of white blood cells, neutrophils, lymphocytes, and neutrophil-to-lymphocyte ratio significantly differed between the groups (p <0.001). Neutrophil-to-lymphocyte ratio was positively correlated with steatosis grade (p < 0.001). CONCLUSIONS: Neutrophil-to-lymphocyte ratio increases with increasing grade of non-alcoholic fatty liver disease in patients with type 2 diabetes, and may be a convenient marker to follow progression of non-alcoholic fatty liver disease. (Acta gastro-enterol. belg., 2016, 79, 295-300).

Is Allergic Rhinitis a Factor That Affects Success of Tympanoplasty?

OBJECTIVE: The aim of the present study was to investigate the effect of allergic rhinitis on the success of the operation in chronic otitis surgery by using score for allergic rhinitis (SFAR). MATERIALS AND METHODS: In the present study; 121 patients, who underwent type 1 tympanoplasty were examined retrospectively. SFAR of all patients were recorded. The graft success rates of 26 patients with allergic rhinitis (AR) and 95 patients with no allergic rhinitis group (NAR) were compared. RESULTS: While the graft success rate in NAR group was 89.5%, this rate was 80.8% in the AR group. However, the difference between groups was not statistically significant (p = 0.311). CONCLUSION: These findings suggest that allergic rhinitis decreases the graft success rate of the pathologies occurring in eustachian tube, middle ear and mastoid although statistically significant difference wasn't found. Prospective studies with larger patient groups are required in order to evaluate this pathology.

Anti-inflammatory and anti-oxidative effects of alpha-lipoic acid in experimentally induced acute otitis media.

OBJECTIVES: To investigate the anti-inflammatory, anti-oxidative and tissue protective effects, as well as the potential therapeutic role, of alpha-lipoic acid in experimentally induced acute otitis media. METHODS: Twenty-five guinea pigs were assigned to one of five groups: a control (non-otitis) group, and otitis-induced groups treated with saline, penicillin G, alpha-lipoic acid, or alpha-lipoic acid plus penicillin G. Tissue samples were histologically analysed, and oxidative parameters in tissue samples were measured and compared between groups. RESULTS: The epithelial integrity was better preserved, and histological signs of inflammation and secretory metaplasia were decreased, in all groups compared to the saline treated otitis group. In the alpha-lipoic acid plus penicillin G treated otitis group, epithelial integrity was well preserved and histological findings of inflammation were significantly decreased compared to the saline, penicillin G and alpha-lipoic acid treated otitis groups. The most favourable oxidative parameters were observed in the control group, followed by the alpha-lipoic acid plus penicillin G treated otitis group. CONCLUSION: Alpha-lipoic acid, with its antioxidant, anti-inflammatory and tissue protective properties, may decrease the clinical sequelae and morbidity associated with acute otitis media.

Is there any association between irritable bowel syndrome subgroups and autonomous dysfunction.

OBJECTIVE: Irritable bowel syndrome (IBS) is a common functional intestinal disorder. Although there are marked improvements in the conceptualization of IBS pathophysiology in brain-intestinal interaction disorder, there is no definite consensus in the role of autonomic dysfunction (AD) in disease development and symptom progression. The aim of this study was to evaluate autonomous dysfunction in IBS subgroups. PATIENTS AND METHODS: A total of 50 patients and 49 healthy controls were included. IBS subgroup types and demographic characteristics of patients were recorded. AD investigations were made up of parasympathetic and sympathetic tests. RESULTS: There was no statistically significant difference was determined between the groups in accordance to demographic characteristics such as age, gender, BMI and resting heart rate (p > 0.05). Three parasympathetic and one sympathetic autonomic neuropathy tests were found significantly different (respectively p < 0.001, p = 0.001, p = 0.016, p < 0.001, p = 0.375). There were significant decreases in parasympathetic tests in IBS-C patients; however, in the control group, there were significant decreases in sympathetic tests when compared with IBS-D patients (p < 0.001). The severity of AD in IBS-C subgroup was more pronounced than the IBS-D subgroup. No correlation was determined between dysautonomia and disease duration (p > 0.05). CONCLUSIONS: AD may have a role in IBS pathophysiology. Deterioration of the autonomous system not only affects the gastrointestinal system but also other systems including the cardiovascular system. Patients may also be susceptible to more diverse problems.
