RESUMO
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.

OBJECTIVE: Fabella is a sesamoid whose prevalence is unstable and can be found as bone or cartilage, which changes over time. This study aims to reveal the prevalence, distribution, gender differences, and morphometric characteristics of cartilage and bony fabella in the Turkish population. PATIENTS AND METHODS: The study included 2.035 individuals over 18 years of age. MR images of 121 individuals, whose MR images of both knees could be obtained by anteroposterior and lateral radiographs of the participants, were evaluated retrospectively. RESULTS: The prevalence of fabella was 39.6% in females, 38.4% in males, and 38.8% in total. The prevalence of cartilage fabella was 9.1%, whereas bone fabella incidence was 29.7% regardless of gender. The fabella's mean thickness, width, length, and distance to the epicondylus lateralis femoris were 3.84 mm, 6.04 mm, 6.23, and 31.26 mm, respectively. CONCLUSIONS: The data of this study showing the occurrence and morphometric characteristics of bony and cartilaginous fabella allow early and accurate diagnosis of various pathological conditions caused by fabella.

BACKGROUND: Osteoporosis is a common public health problem in chronic kidney patients. The risk factors for osteoporosis in patients with nondialysis CKD have not been fully investigated. It is not known exactly whether the risk factors of osteoporosis in the general population are also valid for the nondialysis CKD patients. Aims: This study aims to determine the frequency of osteoporosis and the risk factors for osteoporosis in nondialysis CKD patients. PATIENTS AND METHODS: Our study was performed with 283 nondialysis stage 3-5 CKD patients. According to the BMD results, the patients were classified into groups as normal, osteopenia and osteoporosis according to World Health Organization criteria. Monocyte/high-density lipoprotein-cholesterol ratio (MHR), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) were calculated individually for all cases. RESULTS: According to our BMD results, 67 (24%) patients were found to have osteoporosis. In the osteoporosis patient group, compared to the normal BMD group, females were higher and the mean age was higher (P = 0.025, P = 0.028). Body mass index (BMI) and eGFR were lower in the osteoporosis group (P = 0.013). Parathyroid Hormone and Platelet-to-lymphocyte ratio in the patients in the osteoporosis group was higher than of those in the normal group (P = 0.026, P = 0.035). In the multivariate logistic regression analysis, advanced age, female gender, and low BMI were determined as independent risk factors for the development of osteoporosis in nondialysis CKD patients. CONCLUSION: Advanced age, female gender and low BMI are the risk factors for osteoporosis in nondialysis CKD patients. It may be a rational approach to measure BMD for the diagnosis of osteoporosis in nondialysis CKD patients who are elderly, female and have low BMI.

aimed to evaluate the laboratory parameters, risk factors, and success in predicting mortality in COVID-19 patients admitted to our hospital's intensive care units (ICUs). METHODS: Levels of procalcitonin, ferritin, D-dimer, CRP and albumin measured on days 1 and 7 were recorded. Patients were divided into two groups as non-survivors and patients, who were discharged from ICUs. The predictive values of laboratory parameters in predicting COVID-19 mortality were investigated. RESULTS: A statistically significant difference was detected between the two groups in the mean values of all laboratory parameters tested on days 1 and 7, including D-dimer, procalcitonin, CRP, WBC, ferritin (excluding only D-dimer levels and WBC counts on day 1; p=0.061 and p=0.243, respectively) (p<0.001, p<0.001, p<0.001, p=0.013, p<0.001, p<0.001, p<0.001, p<0.001, p<0.001, p<0.001; respectively). CONCLUSION: . It can be argued that procalcitonin, ferritin, and D-dimer can be guiding parameters in predicting mortality in COVID-19 because their levels were found to be significantly higher in non-survivors. D-dimer, procalcitonin, and ferritin showed an almost high level of sensitivity and specificity in predicting mortality (Tab. 5, Fig. 3, Ref. 19).

BACKGROUND AND AIM: Acute pancreatitis (AP) is a life- threatening condition across all age groups. In this study, it was aimed to investigate the severity of the disease and associated mortality in the geriatric population. METHODOLOGY: This single-center, prospective study elderly (≥65 years of age) and younger (18-65 years of age) total 147 patients with AP are enrolled To diagnose and asses the severity of AP Atlanta classification was used. Baseline and 12-months follow-up data included Ranson, Imrie, BISAP, APACHE-II, SOFA, Modified Marshall, Balthazar, and Computed Tomography Severity Index (CTSI) as prognostic tools. RESULTS: 6 (15%) patiens in elderly and 5 (6,7%) patients in non elderly group had modarete-severe AP . Patients were followed up 1 year and during this time no systemic complications were seen , 8 (20%) patients in elderly group and 10 (13,6%) patients in younger group had local complications. 1 patients in elderly and 2 patients in non elderly group had acute necrotic collection whereas 1 patient developed walled of necrosis in non elderly group. The elderly patients with any of the following index characteristics would not be expected to have a mild disease course: Imrie score ≥ 3, BISAP score ≥ 3, APACHE-II ≥ 11, CRP ≥ 195 mg/dl. CONCLUSIONS: AP caused a prolonged hospitalization in the elderly compared to younger patients but its severity and clinical outcomes were not different in the two groups.

OBJECTIVE: We aimed to investigate the potential relationship between plasma alarin levels and type 2 diabetes mellitus (T2DM). PATIENTS AND METHOD: We included 154 participants, divided into four groups in a cross-sectional study design. The first group includes patients with T2DM without complications (n=30), the second group patients with T2DM with microvascular complications (T2DM-noC n=32), the third group patients with T2DM with macrovascular complications, T2DM-MV (n=32) and the last group is the healthy control group (n=60). RESULTS: In our study 94 patients were diabetic; 47 females and 47 males. The control group consists of 60 people, 30 women and 30 men. It was found that these had a significant (p>0.05) variation in serum alarin levels among the T2DM (T2DM-noC=3.1±0.7 ng/mL T2DM-mV=2.8±0.4 ng/mL, T2DM-MV= 3.6±0.4 ng/mL) versus control group (15.6±2.6).We failed to find a significant variation of serum alarin levels (p>0.05) between T2DM subgroups. Serum alarin levels were significantly higher among control patients (p<0.05). There was no difference between diabetic sub-groups. CONCLUSION: We concluded that serum alarin levels in patients with T2DM are lower than in normal people. Further studies are needed to investigate the possible prognostic value of alarin in clinical practice in T2DM.
RESUMO
Cutaneous side effects associated with sunitinib use are a major problem in patients receiving cancer treatment. The aim of this study was to investigate the protective effect of adenosine triphosphate (ATP) against possible skin damage resulting from sunitinib use in rats. Thirty Albino Winstar rats were divided into the following three groups: healthy controls (HCs, n = 10), sunitinib (SUN, n = 10), and sunitinib + ATP (SAT, n = 10). ATP was injected intraperitoneally at a dose of 2 mg/kg. One hour subsequent to the administration of ATP and 0.9% NaCl, the SAT and SUN groups were orally administered a dose of 25 mg/kg sunitinib to the stomach. Macroscopic evaluation of the skin indicated lower levels of skin damage in the SAT group than in the SUN group. As an indicator of oxidative stress, malondialdehyde (MDA), total oxidant status (TOS), and oxidative stress index (OSI) levels were significantly higher in the SUN group than in the HC group, while total glutathione (tGSH) and total antioxidant status (TAS) levels were significantly lower. However, MDA, TOS, and OSI levels were significantly lower in the SAT group than in the SUN group, while tGSH and TAS levels were significantly higher. Histopathological examination revealed keratin plugs with edema, vasopathology, and inflammatory cell infiltration in the SUN group. The SAT group showed less necrotic epithelium, keratin plugs, edema, and vasopathology than the SUN group. ATP can be effective in preventing skin damage caused by sunitinib use by reducing oxidative stress.

AIMS: Chronic kidney disease (CKD) is a serious health problem due to high mortality and morbidity, negative impact on the patients' quality of life (QOL), high diagnostic and therapeutic cost, and the burden on society. Sleep, which is one of the main needs of the human body, is important regarding the health and QOL in all ages. The objective of our study was to plan the quality of sleep and life quality in adults with CKD. MATERIALS AND METHODS: Total 240 cases (91 healthy volunteers, 75 predialysis patients, and 74 hemodialysis (HD) patients) were included in our study. Our study was designed as a prospective survey with a face-to-face interview method. The sleep quality was evaluated with Pittsburgh Sleep Quality Index (PSQI). The WHO Quality of Life-short version (BREF) survey questions were used for QOL, and scoring was performed. RESULTS: The analysis showed that the results of PSQI scores, QOL scores, and evaluation of the age variable were statistically significant (P = 0.001, P < 0.001, P < 0.001, respectively). Likewise, the PSQI scores were low in healthy volunteers but were the highest in predialysis patients. The scores of the HD patients were between the scores of predialysis and healthy volunteers. The score of the QOL increased with educational level. There was a positive correlation between Modification of Diet in Renal Disease (MDRD) level and QOL (P < 0.001; r = 0.260) and a negative correlation between MDRD level and PSQI score (P < 0.001, r = -0.202). CONCLUSION: Like in HD patients, close follow-up of predialysis patients with CKD is critical considering the resolution of the encountered problems. We believe that the increase in QOL and sleep in patients with CKD may decrease the morbidity.

INTRODUCTION AND OBJECTIVE: IMA and MPO are elevated in serum in case of end-stage renal disease. Epicardial fat tissue thickness has been considered an indicator for cardiovascular diseases recently. The present study was aimed to examine the relationship of epicardial fat tissue thickness (EFTT) with IMA and MPO levels in patients with CKD. MATERIALS AND METHODS: Predialysis CKD patients admitted to the Nephrology outpatient clinic, patients on haemodialysis and healthy volunteers were included, 111 patients were in the study. EFTT measurement was performed with the transthoracic view using an ECHO device. RESULTS: The analysis conducted among the groups in terms of IMA, MPO levels, and EFTT revealed a statistically significant difference (p < 0.001). It was determined to be the lowest in the healthy volunteers, slightly increased in the pre-dialysis group whereas it was quite high in the haemodialysis group. According to the correlation test performed, we observed that IMA, MPO levels, and EFTT were found to be highly correlated to progression of CKD. CONCLUSION: We believe that we have introduced three novel follow-up parameters, such as: IMA, MPO, EFTT to literature for the follow-up of CKD. As the levels of IMA MPO and EFTT increase, the severity of CKD increases (Tab. 4, Fig. 1, Ref. 25).

OBJECTIVE: To investigate the insulin resistance and serum resistin levels in women with idiopathic hirsutism compared to controls and women with polycystic ovary syndrome (PCOS). PATIENTS AND METHODS: Three groups of women including 23 women with idiopathic hirsutism, 28 women with PCOS and 28 non-hirsute women serving as controls were included into the study. The Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), serum fasting insulin and resistin levels were compared between the groups. RESULTS: There were no statistically significant differences regarding the age, BMI and waist circumferences between the groups. Mean and median fasting blood glucose, fasting insulin, HOMA-IR, serum resistin levels were statistically similar between the groups (p = 0.966, p = 0.378, p = 0.409 and p = 0.784, respectively). There were no correlations between the resistin, HOMA-IR, fasting insulin levels and BMI in any of the three groups. CONCLUSIONS: Insulin resistance and serum resistin levels do not appear to be increased in women with idiopathic hirsutism compared to controls at similar BMI's and waist circumferences.

To assess the association of polymorphisms of toll-like receptors (TLRs) 2, 3 and 4 with the delay in onset of labour at term pregnancies, patients delivering at > 37 weeks and without pre-eclampsia, IUGR or a history of preterm delivery were prospectively evaluated. TLR2 Arg753Gln, TLR3 (c.1377C/T) and TLR4 Asp299Gly and Thr399Ile polymorphisms were genotyped by using PCR-RFLP. Patients labouring spontaneously before the 41st week were compared with those who did not labour spontaneously until this week in terms of baseline characteristics, TLR 2, 3 and 4 polymorphisms. The same comparisons were also performed by using a 40th week cut-off. Chi-square test, two-sample t-test or Mann-Whitney U tests were used for comparisons, as appropriate. In total, 79 patients delivering after 37 weeks were evaluated. All had CC genotype for TLR2 Arg753Gln and TLR4 Thr399Ile. There were no significant differences for TLR4 Asp299Gly GA and TLR3 (c.1377C/T) polymorphisms between patients spontaneously entering or not entering labour until the 41st week; the same was true when the 40th week cut-off was used. Delay in onset of labour at term pregnant women does not seem to be affected by the presence of TLR 2, 3 or 4 polymorphisms. Further studies are needed.

PURPOSE: Polycystic ovary syndrome (PCOS) is a common endocrine disorder which is associated with multiple risk factors for atherosclerosis. The aim of this study was to investigate the CIMT which is used in the early diagnosis of atherosclerosis and visceral obesity by ultrasound in newly diagnosed polycystic ovary syndrome with normal body mass index. MATERIALS AND METHODS: A case-control study was conducted on 25 PCOS women (18-30 years of age) and 25 controls. BMI was matched volunteer controls. Carotid intima media thickness (CIMT) and fat distribution as visceral fat thickness (VFT) with subcutaneous fat thickness (SFT) were measured by ultrasound. After, visceral fat ratio (VFR) fat ratio (VFR) was calculated using VFT divided by SFT. The variables were compared using the χ(2)-test and Student's t test. RESULTS: Comparing women with PCOS to the control group showed that CIMT was similar in both groups (p=0.84). The VFT in the PCOS group was higher than the control group (p=0.048). Whereas, the SFT was higher in the control group when compared to women with PCOS (p=0.007). The VFR was significantly higher in women with PCOS when compared to the control group (1.12 ± 0.38 vs. 0.81 ± 0.34; p=0.005). CONCLUSIONS: CIMT which used as early atherosclerosis predictors have not increased in newly diagnosed PCOS women. Body fat distribution was observed in visceral area in the newly diagnosed PCOS women. VFR follow up may provide benefit as a quantitative method for the assessment and follow up of visceral obesity in women with PCOS.

BACKGROUND: The aim of this study was to evaluate the changing of TK1 (where TK is thymidine kinase) activity before and after adjuvant chemotherapy in patients with breast and colorectal cancer. METHODS: The study included 16 breast cancer, 25 colorectal cancer, and 38 healthy volunteers as the control group. Blood samples were taken twice from each patient; first at the beginning of the chemotherapy and second after six cycles of chemotherapy. TK1 activity was measured enzyme immunoassay method. RESULTS: The mean TK1 activity in the breast and colorectal cancer was significantly higher than the controls. TK1 activity in the colorectal cancer was higher than the breast cancer but this difference was not significant. TK1 activity after six doses of chemotherapy was lower than baseline TK1 activity before the start of chemotherapy in breast and colorectal cancer. TK1 activity was positively correlated with CA15-3, before and after chemotherapy in patients with breast cancer. TK1 activity in the colorectal cancer was also positively correlated with CA19-9, before and after chemotherapy. The values for the cutoff point, sensitivity, specificity, and the area under curve were determined for TK1 as >44.36 Du/L, 68.29%, 100% and 0.819, respectively in all subjects. CONCLUSION: Our results showed that serum TK1 activity in patients with breast and colorectal cancer was significantly higher than that of the healthy controls. Moreover, after the completion of chemotherapy the values were lower than baseline. Pretreatment TK1 activity should be considered as a useful marker for assessment tumor cell proliferation in breast and colorectal cancer. Further work is needed to understand TK1 activity better in large populations of patients with solid tumor.

We reviewed the long-term radiological outcome, complications and revision operations in 19 children with quadriplegic cerebral palsy and hip dysplasia who underwent combined peri-iliac osteotomy and femoral varus derotation osteotomy. They had a mean age of 7.5 years (1.6 to 10.9) and comprised 22 hip dislocations and subluxations. We also studied the outcome for the contralateral hip. At a mean follow-up of 11.7 years (10 to 15.1) the Melbourne cerebral palsy (CP) hip classification was grade 2 in 16 hips, grade 3 in five, and grade 5 in one. There were five complications seen in four hips (21%, four patients), including one dislocation, one subluxation, one coxa vara with adduction deformity, one subtrochanteric fracture and one infection. A recurrent soft-tissue contracture occurred in five hips and ten required revision surgery. In pre-adolescent children with quadriplegic cerebral palsy good long-term outcomes can be achieved after reconstruction of the hip; regular follow-up is required.

BACKGROUND: Among the various sutureless techniques, fibrin glue has proved to be effective in the treatment of peptic ulcer perforation as an alternative to classical suture repair. Albeit rare, a potential disadvantage of fibrin glue use is viral transmission or anaphylaxis. The aim of this study is to introduce a new technique for the closure of duodenal perforation using a novel recombinant enamel protein called amelogenin. METHODS: In this case-control experimental study, 32 adult male Wistar Albino rats weighing 250-300 g were randomly divided into four groups, each containing 8 rats. Duodenal perforation of 0.2 cm were performed in the postpyloric region in all rats. Each group received primary repair, primary repair with omentoplasty, fibrin glue, and amelogenin, respectively. All animals were killed on the postoperative day five and the bursting pressure measurements, hydroxyproline levels and histopathologic values of the wound site were evaluated. RESULTS: Bursting pressure levels of the fibrin glue and amelogenin groups were significantly lower than the primary repair and primary repair with omentoplasty groups (P < 0.05) However, no significant difference existed between the fibrin glue and amelogenin groups in this respect (P > 0.05). There was also no statistically significant difference among all groups regarding tissue hydroxyproline levels and histopathologic values (P > 0.05). CONCLUSION: Application of amelogenin as an alternative sutureless repair technique did not improve wound healing in this animal model of duodenal perforation.

This study demonstrates a biological route to programming well-defined protein-inorganic interfaces with an arrayed geometry via modular peptide tag technology. To illustrate this concept, we designed a model multifunctional fusion protein, which simultaneously displays a maltose-binding protein (MBP), a green fluorescence protein (GFPuv) and an inorganic-binding peptide (AgBP2C). The fused combinatorially selected AgBP2C tag controls and site-directs the multifunctional fusion protein to immobilize on silver nanoparticle arrays that are fabricated on specific domain surfaces of ferroelectric LiNbO(3) via photochemical deposition and in situ synthesis. Our combined peptide-assisted biological and ferroelectric lithography approach offers modular design and versatility in tailoring surface reactivity for fabrication of nanoscale devices in environmentally benign conditions.

PURPOSE: Many different remedial operations for alkaline reflux gastritis have been described. Analysis of their efficacy is difficult, because while many of the procedures have good early results, there are long-term failures due to their own complications. The aim of this study is to evaluate our experience with patients undergoing remedial operations for alkaline reflux gastritis syndrome. MATERIAL AND METHODS: The clinical features and results of remedial operations of 65 patients with alkaline reflux gastritis syndrome were reviewed retrospectively. Data on the hospital course were collected by interviewing patients directly or by telephone contact. An assessment of each patient's response to remedial operation was then made and a Visick score assigned. RESULTS: All patients had been tried on a medical treatment and dietary restriction or both prior to remedial operation. Long-term follow up was possible in 46 patients. Seventy-six percent of patients who at the final state had a truncal vagotomy, distal gestrectomy and Roux-en-Y gastrojejunostomy have been found to show satisfactory results (Visick-I/Visick II). Three patients who had previously undergone a Roux-en-Y conversion later required re-operation for Roux-stasis syndrome and a near-total gastrectomy was performed on these patients. Other operations performed for alkaline reflux gastritis were converted to "uncut" Roux-en-Y in five patients and dismantling of gastrojejunostomy in two patients. CONCLUSIONS: For patients unresponsive to medical treatment, we reccommend the following strategy: a) for patients with truncal vagotomy plus gastrojejunostomy, dismantling of gastrojejunostomy should be the first choice b) for patients with prior Billroth-II gastrectomy, Roux-en-Y conversion is the most effective corrective operation, although it has its proper including Roux statis syndrome.

Amyand's hernia (AH) is defined as an appendix located in the inguinal hernia sac. Most cases are diagnosed intraoperatively and might undergo appendectomy besides hernia repair. Computerized tomography is effective in the preoperative diagnosis. Meanwhile, the number of reports concerning the preoperative diagnosis of AH is increasing. There is no standard protocol for the management of AH. Factors such as the presence of an inflamed appendix, contamination of the surgical field, patient age and anatomic features of the tissue are important determinants for appropriate surgery. Herein, we report an adult male patient with AH.
