ABSTRACT

OBJECTIVE: The current study aimed to examine the psychiatric symptoms that can be seen in fibromyalgia (FM) patients, their attitudes toward seeking psychological help, and their concerns about stigma. Besides, it was investigated whether the stigma concerns that they may experience about receiving psychiatric treatment constitute an obstacle for patients to receive psychiatric treatment. SUBJECTS AND METHODS: This cross-sectional descriptive study was conducted between February and July 2020. Various seeking help were measured with Attitude Towards Seeking Psychological Help Scale-Short Form (ATSPPH-SF), Self-Stigma in the Process of Seeking Psychological Help Scale (SSPSPHS), Intention to Seek Psychological Help Inventory (ISPHI), and Social Stigma Due to Seeking Psychological Help Scale (SSDSPHS). FM symptoms of patients were measured with The Symptom Screening Questionnaire, Revised 90 Items (SCL-90-R). Quality-of-life parameters were measured with Fibromyalgia Impact Questionnaire (FIQ). RESULTS: Fibromyalgia patients had higher somatization (p=0.001), psychotism (p=0.045) and phobic anxiety (p=0.015) scores than controls. The ATSPPH-SF (p=0.002) and SSPSPHS (p=0.043) scale scores of the FM patients were higher than the controls. There was a significant positive correlation between FIQ and SSPSPHS (r=0.288, p=0.043) and SCL-90 overall (r=0.602, p<0.001) and all subscales scores. Patients with high active psychotic symptom levels had higher FM exposure scale scores and SCL-90 overall scores than those with low active psychotic symptom levels (p<0.001). CONCLUSIONS: The findings of this study showed that fibromyalgia patients have more somatization symptoms than healthy individuals, and as psychiatric symptoms increase in these individuals, their level of being affected by FM increases.

ABSTRACT

Context: The relationship between life changes and glycemic control in children with type 1 diabetes during the pandemic period was examined. Objective: We aimed to investigate the effect of the pandemic period on 66 children (aged 5-18 years) with type 1 diabetes using scales evaluating family functionality, nutritional habits, adherence to treatment and depression status. Design: It is a cross-sectional clinical and laboratory study using certain scales for its descriptive features. Subjects and Methods: Demographic characteristics, anthropometric measurements, laboratory investigations were evaluated. Family functionality of the patients were evaluated with Smilkstein's family APGAR scale, motivation and knowledge levels were evaluated with the 6-item Morisky medication adherence scale (MMAS-6), nutritional habits were evaluated with the Mediterranean diet quality index (KIDMED), and depression status was evaluated with the children depression inventory (CDI). Results: The mean HbA1c level increased significantly in the first year of the pandemic compared to the onset of the pandemic period (8.5% vs. 8.9%, p: 0.003). In the responses to these scales, children with diabetes have high family functionality (89.4%), high motivation (90.9%) and high knowledge level about adherence to treatment (97%). Furthermore, healthy eating habits (high KIDMED index scores 92.4%), and low degree of depression score (95.5%) have been observed. We detected a statistically significant positive correlation between HbA1c and CDI scores (r: 0.27; p: 0.02), and a negative correlation between HbA1c and MMAS-6 motivation score (r: -0.30; p: 0.01). Conclusions: In this study, the effect of motivation and mood changes on glycemic control was more clearly demonstrated.

ABSTRACT

OBJECTIVES: Platelet (PLT) indices are predictive in many diseases and conditions. The relationships of these indices with proteinuria and progression of renal disease are not well known. This study aimed to assess PLT indices in patients with primary glomerular nephrotic range proteinuria (PGNRP), with and without chronic kidney disease (CKD), and to compare these indices with those of healthy individuals (His). METHODS: This cross-sectional study was performed from January 2015 to May 2015. HIs (n = 57) and patients with PGNRP (n = 41) were enrolled. PLT indices and blood biochemistry parameters were compared between HIs and patients with PGNRP, as well as between subgroups of patients with PGNRP who had CKD (n = 23) and those who did not have CKD (n = 18). RESULTS: There were no statistically significant differences in any PLT indices (i.e., platelet number, mean platelet volume, plateletcrit, and platelet distribution width) between HIs and patients with PGNRP, or between the subgroups of patients with PGNRP. However, patients with PGNRP who had CKD exhibited higher median C-reactive protein and mean albumin levels, compared with patients who did not have CKD. CONCLUSIONS: Pathological processes in proteinuria and CKD are not associated with PLT indices.

ABSTRACT

Systemic sclerosis (SSc) is an autoimmune connective tissue disease with multisystem involvement. An increased incidence of cancer in SSc patients compared with the general population has been reported in several reports. Our aims in this study were to determine the most common malignancies and to investigate the possible risk factors for the development of malignancy in patients with SSc. Three hundred forty SSc patients from 13 centers were included to the study. Data of the patients were obtained by evaluating their medical records retrospectively. A total of 340 patients with SSc were evaluated. Twenty-five of the patients had 19 different types of malignancy. Bladder cancer was the most common type of cancer with four patients and was followed by breast cancer with three patients, and cervix cancer and ovarian cancer with two patients each. Other types of cancers such as squamous cell skin cancer, adenocancer with an unknown origin, multiple myeloma, chronic myeloid leukemia, papillary thyroid cancer, larynx cancer, non-small cell lung cancer, follicular type non-Hodgkin lymphoma (NHL), endometrium cancer, colon cancer, uterus cancer, neuroendocrine tumor, glioblastoma multiforme, and soft tissue sarcoma were diagnosed in one patient each. The only cancer type that showed an association with cyclophosphamide dose was bladder carcinoma. Other malignancies did not show a correlation with age, sex, smoking, type and duration of the disease, autoantibodies, organ involvement, and dose and duration of cyclophosphamide therapy. Cancer may develop in any organ in patients with SSc. Continuous screening of the patients during a follow-up period is necessary for the early detection of the tumor development.

ABSTRACT

Rheumatoid arthritis (RA) is a major cause of adult chronic inflammatory arthritis and an autoimmune disease of unknown etiology in which the inflammatory pathology involves T cell activation. Genetic mutations in the Mediterranean fever (MEFV) gene, encoding pyrin, influence the severity of RA, but the underlying mechanisms are not completely understood. In this study, we investigated whether the full-length MEFV gene (MEFV-fl) and the exon 2-deleted splice isoform (MEFV-d2) expression are associated with or responsible for the clinical conditions of RA. This study include 47 patients with RA and 47 age- and gender-matched healthy controls. Quantitative real-time polymerase chain reaction analysis was performed to examine transcriptional changes in MEFV gene expression from peripheral blood samples. Reverse transcription-polymerase chain reaction of peripheral blood cells revealed the downregulation of MEFV-fl mRNA in non-treated patients compared with healthy controls and treated patients. MEFV-d2 expression was not different between groups. This is the first study to investigate the expression of MEFV transcript in RA. Deregulation of the MEFV gene is likely to result in uncontrolled inflammation as observed in RA. Therefore, downregulation of MEFV-fl may be involved in the pathogenesis of early-stage RA and treatment and may ameliorate MEFV-fl expression.

ABSTRACT

Bcl-2 and Bax proteins are expressed in cells of the tails of Pelophylax ridibundus larvae. We investigated the levels of these proteins in tails undergoing apoptosis. Apoptotic cells were observed in the epidermis, muscle and notochord of tails of different lengths. The apoptotic cells in epidermis exhibited the typical features of apoptosis. Amorphous masses and irregularities in striated muscle tissue undergoing apoptosis and apoptotic remnants in the notochord also were observed. In general, Bax staining in the epidermis, subepidermal fibroblast layer, muscle and notochord cells increased, while Bcl-2 staining decreased as the tail regressed. Our results suggest that during tail regression due to metamorphosis, Bcl-2 and Bax proteins play key roles in the apoptosis of tail epidermis, subepidermal fibroblast layer, muscle and notochord cells.

ABSTRACT

BACKGROUND: Scleroderma is a chronic inflammatory disease characterized by widespread fibrosis of the skin and the internal organs. Ghrelin is a polypeptide hormone produced by various tissues and inflammatory cells. In experimental studies, ghrelin has been shown to have anti-inflammatory and antioxidant effects, in addition to its metabolic actions. AIM: To evaluate the potential preventive effects of ghrelin on a mouse model of bleomycin (BLM)-induced scleroderma. METHODS: This study involved five groups of BALB/c mice (n = 7 in each group). Mice in the control group received 100 µL/day of phosphate-buffered saline (PBS) subcutaneously, while the other four groups were given 100 µg/day of BLM (dissolved in 100 µL PBS) subcutaneously. Three of the BLM-treated groups received intraperitoneal doses (10 ng/kg/day) of acylated, nonacylated or total ghrelin. Animals were killed at the end of the fourth week, and blood and tissue samples were collected for further analysis. Dermal thickness, serum levels of transforming growth factor-ß1, numbers of inflammatory cells on the dermal layer and numbers of α-smooth muscle actin-positive cells were determined. RESULTS: BLM increased dermal thickness, numbers of inflammatory cells on the dermal layer and activity of the myofibroblastic cells. Application of acylated, nonacylated and total ghrelin decreased the infiltration of inflammatory cells and the activity of the myofibroblastic cells, and reduced dermal fibrosis. CONCLUSIONS: Based on these results, it appears that ghrelin has an antifibrotic action, in addition to the anti-inflammatory and antioxidant effects that have been documented previously. The pathogenic and therapeutic roles of ghrelin in scleroderma should be evaluated by further studies.

ABSTRACT

Many populations of the narrow-clawed crayfish Astacus leptodactylus in Turkey, including those inhabiting Lake Egirdir, declined drastically in the mid-1980s due to introduction of crayfish plague Aphanomyces astaci. However, unlike many other localities, there has been some recovery in the A. leptodactylus population inhabiting this lake even though crayfish plague has been suspected to have persisted since then. In support of this, DNA from 5 of 34 healthy-looking crayfish sampled recently from the lake tested positive by both conventional and real-time PCR using species-specific primers targeting the rDNA internal transcribed spacer region, and product sequence analysis confirmed the identification of A. astaci. This complies with other recent reports of coexistence of native European crayfish with this pathogen, and further research is now needed to identify the key mechanisms allowing it.

ABSTRACT

BACKGROUND: T lymphocytes induce the transformation of fibroblasts into myofibroblasts, the main mediators of fibrogenesis. The inosine 5'-monophosphate dehydrogenase inhibitor mycophenolate mofetil (MMF) and the anti-CD25 monoclonal antibody daclizumab (DCZ) have been reported to suppress the proliferation of T lymphocytes. AIM: To evaluate the preventive effects of MMF and DCZ in early stages of bleomycin (BLM)-induced scleroderma. METHODS: This study involved five groups of Balb/c mice (n = 10 per group). Mice in four of the groups were injected subcutaneously (SC) with BLM [100 µg/day in 100 µL phosphate-buffered saline (PBS)] for 4 weeks; the remaining (control) group received only 100 µL PBS. Three of the BLM-treated groups also received either intraperitoneal MMF 50 or 150 mg/kg/day, or SC DCZ 100 µg/week. At the end of the fourth week, all mice were killed, and blood and tissue samples were obtained for further analysis. RESULTS: In the BLM-treated group, increases were seen in inflammatory-cell infiltration, α-smooth muscle actin-positive (α-SMA+) fibroblastic cell count, tissue hydroxyproline content, and dermal thickness. Dermal fibrosis was histopathologically prominent. In BLM-treated mice also given MMF or DCZ, inflammatory-cell infiltration, tissue hydroxyproline content and dermal thickness were decreased. In the MMF groups, decreases were also noted in α-SMA+ fibroblastic cell count. CONCLUSION: In this BLM-induced dermal fibrosis model, MMF and DCZ treatments prevented the development of dermal fibrosis. Further studies are needed to evaluate whether targeting T lymphocytes is effective in resolving pre-existing fibrosis in human scleroderma.

ABSTRACT

PURPOSE: To evaluate the role of postoperative radiotherapy (RT) in local control and survival and to identify treatment-related prognostic factors in uterine sarcomas. METHODS: Sixty patients with uterine sarcomas treated with postoperative RT were retrospectively analyzed. Median age was 49.5 years (range 24-78). The stage distribution was as follows: stage I: 60%, II: 11.7%, and III: 28.3%. All patients were treated with pelvic irradiation (dose range 45.6-54.6 Gy). Pelvic control (PC), distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) were calculated. Age, stage, histology, tumor size, type of surgery, residual disease, time interval between surgery and RT were selected as possible prognostic factors for PC and OS. Age, total treatment time, pelvic dose, dose per fraction, and acute side effects were analyzed as probable prognostic factors for late complications. RESULTS: Median follow-up was 84 months. The 10-year PC, DMFS, DFS and OS rates were 84, 67.3, 64 and 61.5%, respectively. Univariate analysis showed that age, residual disease, type of surgery and stage were significant factors for PC; residual disease, type of surgery and stage were significant factors for DMFS; stage was found as the only significant factor for DFS and OS. Total treatment time, pelvic dose, dose per fraction, and acute side effects were significant factors for late complications. CONCLUSION: Although our results suggest improved PC, the role of postoperative RT should be tested in prospective randomized trials.

ABSTRACT

Obesity, characterized by hyperleptinemia and hypoghrelinemia, has become a major health problem all over the world and is associated with an increased risk of complications including insulin resistance, hypertension, dyslipidemia, diabetes mellitus and atherosclerosis. The use of the pancreatic lipase inhibitor Orlistat can help seriously overweight people to achieve and maintain weight loss. The aim of our study was to compare the serum leptin and ghrelin levels in obese subjects who take orlistat with those receiving only dietary treatment. Twenty-one obese patients and 10 control subjects participated. The obese patients were divided into two groups; one group (n=11) took orlistat (120 mg, 3 times daily) and received dietary treatment and the other (n=10) only received the dietary treatment. The study lasted twelve weeks. The concentrations of serum ghrelin, leptin, insulin and C-peptide, and routine biochemical parameters, were measured in both groups. The serum ghrelin level was higher in control (183+/-62 fmol/ml) than obese (59+/-30 fmol/ml) subjects while the plasma leptin level was lower in control (8.7+/-12 microg/L) than obese (36.7+/-19 microg/L) subjects (all p<0.001). BMI and the total blood cholesterol, LDL and triglyceride levels fell significantly after both orlistat and dietary treatment in the obese subjects (all p<0.01), and the plasma ghrelin level rose (p<0.01). The leptin level demonstrated the opposite trend in both groups but only the patients taking orlistat showed a significant change (p<0.05).Taken together, these results show that orlistat has no effect on body weight in obese subjects additional to that conferred by a non-pharmacological life-style intervention. We therefore conclude that weight lost rather than type of treatment might be more valuable in obesity.

ABSTRACT

OBJECTIVES: To evaluate the effects of etanercept and thalidomide in the mouse model of bleomycin-induced scleroderma (BLM-IS). METHODS: This study involved four groups (n = 8 mice in each group). Dermal sclerosis was induced by repeated subcutaneous injections of BLM (10 microg) for 4 weeks in BALB/c mice. Control group received only phosphate-buffered saline. The second group received only BLM; the third and fourth groups were also given an intraperitoneal injection of 100 microg etanercept or 150 mg/kg thalidomide, respectively. RESULTS: BLM increased serum TGF-beta1, tissue hydroxyproline levels and expression of alpha-smooth muscle actin (alpha-SMA), and dermal fibrosis was histopathologically prominent. Although thalidomide had no significant effect, etanercept caused decreases in levels of serum TGF-beta1, tissue hydroxyproline and number of alpha-SMA-positive cells. CONCLUSION: Inhibition of TNF-alpha with etanercept in BLM-IS was resulted in a significant reduction of the dermal sclerosis, collagen accumulation and the number of infiltrating myofibroblastic cells. TNF-alpha may play a key role in the progression of BLM-IS and TNF-alpha antagonists may be useful in the management of scleroderma.

ABSTRACT

It has been emphasized recently that there is a strong association between atrial fibrillation and inflammation. Rheumatoid arthritis (RA), characterized by ongoing inflammatory activity, can increase the risk of atrial arrhythmia. P-wave dispersion has been encountered as a risk factor for atrial fibrillation and the effect of inflammation on P-wave dispersion has not been studied thoroughly. The aim of this study was to examine the effect of ongoing inflammatory activity in RA on P-wave dispersion. The study comprised 82 patients diagnosed with RA and 41 healthy volunteers as controls. Systolic functions of all participants were evaluated by echocardiography. Maximum P-wave duration and dispersion were calculated and found to be significantly increased in the RA group compared with the healthy controls. These parameters were also significantly correlated with C-reactive protein levels. The findings of this study suggest that RA may be associated with increases in P-wave dispersion and maximum P-wave duration, and that this association may result from ongoing inflammation.

ABSTRACT

Systemic lupus erythematosus (SLE) is a systemic, autoimmune disease. SLE patients are prone to infections, and their hospital admissions and mortality are most commonly associated with infections. Necrotizing fasciitis (NF) is a rare, life-threatening infection of the subcutaneous tissue. In this report, NF associated with Streptococcus pneumoniae (SPN) that developed within hours and resulted in death is presented in a 46-year-old female case who was recently diagnosed as SLE and did not receive any medication (steroid, immunosuppressive, etc.) except for etodolac. This case shows that SLE can generate predisposition to NF, and SPN can play a role in NF etiology.

ABSTRACT

It was reported that lipid peroxidation (LPO) products increase in rheumatoid arthritis (RA) patients and increased LPO products reduce many antioxidants. Lipid hydroperoxides (LOOHs) are byproduct of LPO. Paraoxonase (PON), arylesterase (ARE), free sulfhydryl (SH) groups, and ceruloplasmin (CP) are enzymes or proteins with antioxidant characteristics. This study aims to determine the levels of LOOHs and SH, and the activities of PON1, ARE, and CP in RA patients. The study included 47 active RA cases and 23 healthy volunteers. The levels of LOOHs and SH, and the activities of PON1, ARE, and CP were determined using appropriate methods. Student's t test and Spearman's correlation analysis methods were employed in the statistical evaluation. The level of LOOHs was found to be higher (p<0.001), while the level of SH and the activities of PON1, ARE, and CP were found to be lower (p<0.001, <0.001, <0.01, and <0.01, respectively) in the RA patient group when compared with the control group. There was a negative correlation between the level of LOOHs and the activity of PON1 in the patient group (r= -0.420 and p<0.01). The results of our study indicate increased oxidant and decreased antioxidant presence in RA patients. PON1 and ARE are known to have antiatherosclerotic effects in addition to their antioxidant characteristics. As the decrease in these antioxidants, resulting from increased oxidative stress in RA patients, development of atherosclerosis besides tissue injury seems inevitable.

ABSTRACT

BACKGROUND: There are few reports about Stevens-Johnson syndrome, a bullous form of erythema multiforme, that can develop in patients treated with cranial irradiation and antiepileptic drugs, especially with phenytoin. We present a patient who developed toxic epidermal necrolysis, a rare and severe form of Stevens-Johnson syndrome, during cranial radiotherapy and phenytoin treatment. CASE REPORT: A 65-year-old male patient with stage IIIB non-small cell lung carcinoma developed a brain metastasis. The patient was treated with phenytoin and dexamethasone. Palliative total cranial irradiation was performed. On the 23rd day of phenytoin administration, erythema and edema in the radiotherapy area and lips, as well as widespread maculopapular eruptions and rashes in the upper thoracic area were observed. The dermal lesions progressed to bullae and subsequently toxic epidermal necrolysis covering 70% of the whole body surface developed. The patient died within 15 days of appearance of the lesions due to secondary infections, despite supportive and symptomatic treatment. CONCLUSION: Although toxic epidermal necrolysis is a rare toxicity it must always be considered during cranial irradiation and antiepileptic prophylaxis.

ABSTRACT

PURPOSE: Radiotherapy of benign diseases has become a frequently discussed subject while there are neither generally accepted guidelines about the indications of radiotherapy, doses and fractionation schedules nor adequate data about the risks and the effectiveness of irradiation. We have retrospectively analyzed the patients who were irradiated for benign diseases in our department. PATIENTS AND METHODS: During the period 1978-1997, a total of 262 patients were irradiated for benign diseases. Megavoltage equipment was used for irradiation of 253 patients, while the remaining 9 patients were irradiated by orthovoltage equipments. The diseases were grouped in 5 categories, and the distribution of the patients referred and irradiated per year was analyzed. Radiotherapy doses, fractionation, response rates and follow-up were evaluated. RESULTS: The number of irradiated patients has been increasing since the 1990's. The most common indication for irradiation was Graves' ophthalmopathy and the incidence of this group has increased after 1992. On the other hand, the number of patients irradiated for soft tissue, bone and skin diseases, except aggressive fibromatosis, has declined in the past 15 years. Response rates were more than 60% for most of the diseases. The patients' follow-up ranged between 1 and 156 months (median 4 months), but it was rather short for most of them. CONCLUSION: We observed common problems about the irradiation of benign diseases such as variations on the accepted indications, the treatment schedules and followup.
