RESUMO

The aim of this study was to investigate whether there is a relationship between premenstrual syndrome and oxidative stress, visfatin and apelin. The study included 40 women with premenstrual syndrome and 40 healthy women. In all subjects, serum visfatin, apelin and oxidative stress parameters were studied in venous blood samples. The oxidative stress parameters were higher in the premenstrual syndrome group than among the controls, but this difference did not reach statistical significance (p > 0.05). It was found that total antioxidant capacity was similar in both groups. For the insulin-serotonin cycle markers, no significant difference was found between groups in terms of visfatin level (p = 0.893), although apelin was found to be significantly higher in the premenstrual syndrome group when compared with the controls (p < 0.001). According to our results, apelin can be used as an ancillary laboratory test in the diagnosis of premenstrual syndrome.

RESUMO

BACKGROUND: Resistive index (RI) is an indirect measurement of blood flow resistance that can be used to evaluate vascular damage. AIMS: The purpose of this study is to evaluate the association between RI values of orbital and intrarenal arteries by means of Doppler ultrasonography (US). METHODS: We evaluated 103 diabetic patients. As a control group, 30 subjects were examined. The patients were divided into two groups. Group 1 consisted of patients with urinary albumin excretion (UAE) <300 mg/day and estimated glomerular filtration rate (eGFR) levels >90 ml/min (n = 50); Group 2 had a UAE >300 mg/day and/or eGFR levels between 89 and 60 ml/min (n = 53). The association between RI values obtained with Doppler US of the ophthalmic artery, central retinal artery, posterior ciliary artery and intrarenal arteries were calculated. RESULTS: Both orbital and intrarenal arterial RI values in Group 1 and Group 2 were higher than the control group (p = 0.001); furthermore, values were higher in Group 2 than in Group 1 (p = 0.0004/0.029/0.036, p = 0.016, respectively). A positive correlation was found between orbital and intrarenal arterial RI values in Group 2 (r = 0.475, 0.285, 0.363, p < 0.01, respectively). CONCLUSION: Both orbital and renal arterial RI values were shown to be higher than the control group. Further, a trend towards higher RI values was observed with renal disease. RI may be useful as one of the markers for early diagnosis and follow-up of diabetic nephropathy and retinopathy.

RESUMO

AIM: The aim of the study was to investigate the effects of rosiglitazone treatment on insulin resistance (IR) and tumor necrosis factor-alpha (TNF-alpha) levels in non-diabetic chronic kidney disease (CKD) patients with IR. PATIENTS AND METHODS: Thirty non-diabetic CKD patients with IR were enrolled in the study. Patients were grouped into two: group 1 (n = 15) received rosiglitazone 4 mg tablet for 3 months and patients who did not receive rosiglitazone treatment constituted the group 2 (n = 15). Baseline and after rosiglitazone treatment, homeostatis model assessment-insulin resistance (HOMA-IR) and TNF-alpha levels were measured. RESULTS: There were no statistical differences in gender, age, HOMA-IR and TNF-alpha levels among group 1 and group 2 (p > 0.05 for all). Compared to baseline in group 1, significant differences were found in HOMA-IR and TNF-alpha levels after 3 months (p = 0.023; p = 0.001, respectively). CONCLUSIONS: Our study indicates that, rosiglitazone treatment improves the IR and decreases TNF-alpha levels in non-diabetic patients CKD with IR.

RESUMO

BACKGROUND: Methanol intoxication leads liver injury; in contrast melatonin and n-acetyl cysteine (NAC) are known to have protective effects on liver. AIM: We aimed to investigate the ultrastructural effects of melatonin and NAC on livers of methanol intoxicated rats and compare potential protective effects of melatonin and NAC on their liver ultrastructure. MATERIALS AND METHODS: Fifty-six adult male Wistar rats were carried out and were randomized to eight groups that have seven rats each: Control groups (C 6h, C 24h), treated with intragastric (i.g.) 1.0 ml saline; Methanol groups (M 6h, M 24h), treated with a dose of 3 g/kg i.g. methanol; Melatonin plus methanol groups (MEL+M 6h, MEL+M 24h), treated with dose of 10 mg/kg i.p melatonin immediately, following with a dose of 3 g/kg i.g. methanol; NAC plus methanol groups (NAC+M 6h, NAC+M 24h), treated with dose of 150 mg/kg, following with a dose of 3 g/kg i.g. methanol. 24 h group rats were given the same dose of melatonin and NAC 12 h after intoxication. Electron microscopy was used to evaluate histological changes in liver tissue at both 6th and 24th hour. RESULTS: Histopathological damage was found to be higher in methanol-induced intoxicated rats compared with the controls. Extensive tubules of smooth endoplasmic reticulum, increased mitochondria, increased primary lysosomes and some marked openings of bile canaliculus were distinguished. Melatonin administration prevents liver injury especially in early hours and although not as effective as melatonin, NAC also prevents liver injury. CONCLUSIONS: Melatonin is much more efficient than NAC, as well as significantly greater hepatoprotective effect against the liver injury secondary to the methanol intoxication.

RESUMO

BACKGROUND: Hydatid cyst secretes numerous immunomodulatory molecules to the host, and the host reacts these molecules by activating immune response. It is also known that, immune cells generally produce more oxidative products. AIM: In this study, we aimed to evaluate the antioxidant enzyme using catalase (CAT) and oxidant enzyme using lipid hydroperoxide (LOOH) levels in the serum samples before and after the surgical interventions in patients with pulmonary cystic echinococcus (CE). PATIENTS AND METHODS: Forty patients with pulmonary CE who underwent surgery and 40 healthy individuals were enrolled to the study. Patients were divided in two groups; group 1 (n=40) consisted of patients with pulmonary CE, and group 2 (n=40) consisted of healthy subjects. Before and after surgical interventions serum CAT and LOOH levels were measured. RESULTS: Compared to group 2, group 1 had significantly lower CAT and higher LOOH levels before surgery (both p < 0.001). In group 1; CAT levels were significantly increased and LOOH levels significantly increased after the surgical intervention (both p < 0.001). CONCLUSIONS: The present study showed that oxidative stress increased in patients with pulmonary CE, may be consequence of immune response of the host, and these levels decreased after the surgical intervention.

RESUMO

BACKGROUND: Testicular torsion due to oxidative stress results in infertility and testicular damage which can be preventable an important health problem worldwide. AIM: The purpose of the present study was to investigate the changes of malondialdehyde (MDA), total antioxidant status (TAS), total oxidant status (TOS) levels; histopathological alterations; morphology, concentration and motilities of the sperm in post ischemic reperfused (I/R) testis tissue. MATERIALS AND METHODS: Forty adult male Wistar rats were carried out and were randomized to five groups; (1) Control group, (2) Ipsilateral left testis ischemia, (3) Melatonin plus ipsilateral left testis ischemia, (4) Contralateral right testis ischemia, 5. Melatonin plus contralateral right testis ischemia. After 1 h ischemia and 24 h perfusion; MDA, TAS and TOS levels were measured, histopathological alterations were determined using by Johnsen's score (JS) and sperm morphology, concentration, motility were examined. RESULTS: MDA, TAS and TOS levels of the testis tissue did not change in all groups (p > 0.05 for all). JS was decreased in I/R group and melatonin treatment reversed histopathological changes and increased JS both in ipsilateral and contralateral testis. Abnormal sperm rate significantly increased in I/R group and melatonin administration changed abnormal sperm rate to normal. CONCLUSIONS: As a result, the present study demonstrated that testicular damage occurs following I/R without an increase of MDA, TAS and TOS levels. Our results also suggested that melatonin is a potent antioxidant agent in preventing testicular I/R injury, as shown by increased JS and changed abnormal sperm rate.

RESUMO

BACKGROUND: Oxidative stress is believed to have a role in the development of chronic diseases. It is also known that long-term night and shift work in nurses might be associated with many health-related problems like fatigue, sleep problems, anxiety and difficulties in maintaining regular lifestyles. AIM: In this study, we aimed to evaluate the changes of oxidative stress parameters and anxiety indexes of the nurses on day and night shifts. MATERIALS AND METHODS: One hundred and twenty nurses in ordinary service and intensive care unit (ICU) were enrolled to the study. Subjects were divided into 2 groups; group 1 (n = 60) consisted of nurses working in a day shift and group 2 (n = 60) as working in the night shift. Further, both groups were divided in to 2 groups again; group la and 2a (both n = 30) who working in the ICU, group 1b and 2b (both n = 30) in the ordinary service. Just before and the end of the shifts, blood samples were obtained to measure total antioxidant status (TAS) and total oxidant status (TOS). Oxidative stress index (OSI) was calculated. Anxiety index were determined at the end of the shift using State-Trait Anxiety Inventory index. RESULTS: Oxidative stress parameters were increased in all nurses at the end of the day and night shifts (p < 0.05). However, both in service and ICU nurses TAS, TOS, and OSI levels were not significantly different at the beginning and the end of the shifts (p > 0.05). Anxiety indexes of each ordinary service and ICU nurses were found to be similar (p > 0.05). CONCLUSIONS: Ordinary service and ICU nurses' oxidative stress parameters and anxiety indexes were not different and all nurses suffer the similar effects of the shifts both in day and night.

RESUMO

Familial Mediterranean fever is an autosomal recessive disorder characterized by paroxysmal episodes of fever and serosal inflammation. The classical presentation is fever and severe recurrent abdominal pain due to serositis that lasts for one to three days and the resolves spontaneously. Between the episodes patients are asymptomatic. Ninety-five percent of patients with familial mediterranean fever have painful episodes localized to the abdomen, which is usually the dominant manifestation of the disease. Herein, we present a case of 34-year-old man with incomplete abdominal pain episode of familial mediterranean fever limited to the epigastrum and had no cardinals symptoms of this disease. The diagnosis was made by genetic screening. Successful treatment response was achieved by colchicine.

RESUMO

Abstract: It is difficult how to manage acute undifferentiated leukemia in daily practice, but generally, hand mirror morphology provides ease to treat these patients. Thirty-nine years old male patient was admitted to with the complaints of echymosis, and pain at his left buttock due to an intramuscular injection for the treatment of previously diagnosed of the lower respiratory infection. Peripheral blood smear revealed >%50 blasts cells with a moderate nuclear: cytoplasmic ratio and one or more nucleoli. The blast cells showed a hand-mirror morphology and not harboring auer rods. According to the flow cytometric analysis the blastic cells do not represent to be originated from myeloid or lymphoid origin, because the cells harboring both of two cell lineages. AML-like therapy was commenced based on the positive myeloid markers including CD117 and CD135. Even though hand mirror morphology of the blasts usually demonstrates the lymphoid origin and the patients are treated as ALL like therapy, myeloid blasts rarely represents the same morphology, as was in our patient.

RESUMO

OBJECTIVE: In this study, we aimed to investigate the clinicopathological features and survival of CD, which is quite rare and has many unknowns. PATIENTS AND METHODS: This study was conducted by retrospectively evaluating patients diagnosed with CD in six different centers in Turkey. RESULTS: The median age of 33 patients included in the study was 49 and 51.5% (n = 17) of these patients were women. 18 (54.5%) patients were in the hyaline vascular subtype and most of the patients were UCD (n = 20, 60.6%). The most common involvement region was head and neck (n = 19, 57.5%). The UCD group was younger than the MCD group (p=0.027). Visceral lymph node involvement was higher in MCD than in UCD (p=0.001). Similarly, it was observed that there was more hepatomegaly (p=0.035) and splenomegaly (p=0.013) in the MCD group. During the median 19.5 months follow-up period, there were no patients who died. CONCLUSIONS: It was observed that UCD and MCD are different clinical entities. Promising survival times can be achieved with surgical and systemic treatments in both subtypes of this extremely rare disease. However, this result should be supported by well-designed prospective comprehensive studies.

RESUMO

AIM: We aimed to determine the effect of a monthly oral vitamin D on the serum 25-hydroxyvitamin D levels and iPTH levels in patients with CKD. METHODS: This was a prospective controlled trial of 48 patients with CKD stage 3-4. Patients were divided into two groups Group1 the cholecalciferol treatment group, Group 2, the control group. One patient in Group 1, and 3 patients in Group2 were excluded after the baseline 25(OH)D levels were determined to be greater than 30ng/ml. Two patients in Group1, and one patient in Group 2 were excluded after the baseline iPTH was determined to be less than 70 pg/ml and greater than 300 pg/ml. Five patients in both groups were lost to follow-up. Thus, a total of 16 patients in Group 1 and 15 patients in Group2 completed the three month study. Group1 patients received 300,000 IU month oral cholecalciferol. RESULTS: The mean serum 25(OH)D concentration of the group1 was significantly higher at baseline (P=0.039). At the end of the three months; serum 25 (OH) D level increased significantly in Group1 (P=0.001). iPTH level of Group1 was significantly lower at baseline (P=0.034). The values of the group1 before and end of third month was compared, serum Ca (P=0.011), P (P=0.013) level showed significant increase, but no significant increase in the Group 2 (P>0.05). The groups had not a clinically significant change in serum Ca and P level (P>0.05). CONCLUSION: Oral cholecalciferol supplementation can be used safely and effective in reducing iPTH levels and correcting vitamin D insufficiency/deficiency in patients with CKD.

RESUMO

There is an enormous need to make better use of the ever increasing wealth of publicly available genomic information and to utilize the tremendous progress in computational approaches in the life sciences. Transcriptional regulation of protein-coding genes is a major mechanism of controlling cellular functions. However, the myriad of transcription factors potentially controlling transcription of any given gene makes it often difficult to quickly identify the biological relevant transcription factors. Here, we report on the identification of Hnf4a as a major transcription factor of the so far unstudied DnaJ heat shock protein family (Hsp40) member C22 (Dnajc22). We propose an approach utilizing recent advances in computational biology and the wealth of publicly available genomic information guiding the identification of potential transcription factor candidates together with wet-lab experiments validating computational models. More specifically, the combined use of co-expression analyses based on self-organizing maps with sequence-based transcription factor binding prediction led to the identification of Hnf4a as the potential transcriptional regulator for Dnajc22 which was further corroborated using publicly available datasets on Hnf4a. Following this procedure, we determined its functional binding site in the murine Dnajc22 locus using ChIP-qPCR and luciferase assays and verified this regulatory loop in fruitfly, zebrafish, and humans.

RESUMO

OBJECTIVE: Thrombotic thrombocytopenic purpura (TTP) is a rare disease characterized by microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal insufficiency. The association or co-existence of thyrotoxicosis or antithyroid drugs with TTP has not been previously reported. Subject and Results. Herein, we present a 54-year-old female patient newly diagnosed with toxic multinodular goiter accompanying with TTP, possibly triggered by either thyrotoxicosis or antithyroid drugs. CONCLUSIONS: The present report is the first in the literature to demonstrate the co-existence of these two diseases and the use of plasma exchange as a modality to treat both conditions.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate the uric acid (UA) and C-reactive protein (CRP) levels in patients with immune thrombocytopenic purpura (ITP). PATIENTS AND METHODS: Forty patients with newly diagnosed ITP and 40 healthy individuals were enrolled in the study. The patients were divided into two groups; group 1 (n = 40) consisted of patients with ITP, and group 2 (n = 40) consisted of healthy subjects. UA and CRP levels were measured in the blood samples from them. RESULTS: There were no statistical differences in gender, age and body mass index between two groups (p > 0.05 for all). Compared to group 2, group 1 had significantly higher UA levels (p = 0.002), whereas CRP levels were not significantly different (p > 0.05). In ITP patients, serum UA and CRP levels significantly correlated with low platelet count (r = -0.362, p = 0.022; r = -0.383, p = 0.015, respectively); and UA levels significantly correlated with CRP levels (r = 0.436, p = 0.005). CONCLUSIONS: The present study showed that UA levels increased in patients with ITP and negatively correlated with platelet counts. UA levels might be a mediator of inflammation via enhanced production of inflammatory cytokines; they might also be a potential mediator of low platelet count, and could play a pathophysiological role in the development of ITP.

RESUMO

OBJECTIVE: Iron deficiency anemia (IDA) is the most common form of anemia. Impaired intake absorption and blood loss are the main factors in the etiology. Impaired absorption can be caused by a decrease in trace elements such as copper and zinc, which are found in the structure of enzymes that coordinate iron metabolism or act as a catalyst for them, and the existence of Helicobacter pylori (H. pylori), which inhibits iron absorption in the stomach. Serum levels of zinc, copper, and H. pylori antibodies were measured in IDA cases, and correlations with IDA were evaluated. PATIENTS AND METHODS: The study group was composed of 115 IDA cases who were followed at hematology outpatient clinics, and the control group was composed of 92 gender- and age-matched healthy individuals. Patients were diagnosed with iron deficiency anemia according to hemoglobin, serum ferritin, and iron levels and total iron-binding capacity. Serum zinc, copper, H. pylori immunoglobulin A (HpIgA) and immunoglobulin G (HpIgG), vitamin B12, and folic acid levels were examined in the blood specimens collected. RESULTS: No statistically significant difference in zinc and copper serum levels between the study and control groups was observed (p > 0.05 for both groups). Although no difference was observed between the HpIgG levels of the two groups, patients with IDA had a statistically significant increase in HpIgA levels (p < 0.05). Pearson's correlation analysis showed that the zinc levels of the IDA group did not have a correlation with any parameters (p < 0.05 for all). Copper levels had a positive correlation with only the HpIgA level in the IDA group (r = 0.222, p = 0.017). CONCLUSIONS: Trace elements and H. pylori infection did not have a correlation with IDA. Elevated levels of HpIgA and positive correlation of HpIgA with copper levels were observed. The literature review clearly suggests that several points require further explanation, and extensive research with larger samples is required.

RESUMO

Influenza A virus (IAV) infection causes an acute respiratory disease characterized by a strong inflammatory immune response and severe immunopathology. Proinflammatory mechanisms are well described in the murine IAV infection model, but less is known about the mechanisms leading to the resolution of inflammation. Here, we analyzed the contribution of CD11b(+)Ly6C(++)Ly6G(-) cells to this process. An accumulation of CD11b(+)Ly6C(++)Ly6G(-) cells within the lungs was observed during the course of IAV infection. Phenotypic characterization of these CD11b(+)Ly6C(++)Ly6G(-) cells by flow cytometry and RNA-Seq revealed an activated phenotype showing both pro- and anti-inflammatory features, including the expression of inducible nitric oxide synthase (iNOS) by a fraction of cells in an IFN-γ-dependent manner. Moreover, CD11b(+)Ly6C(++)Ly6G(-) cells isolated from lungs of IAV-infected animals displayed suppressive activity when tested in vitro, and iNOS inhibitors could abrogate this suppressive activity. Collectively, our data suggest that during IAV infection, CD11b(+)Ly6C(++)Ly6G(-) cells acquire immunoregulatory function, which might contribute to the prevention of pathology during this life-threatening disease.

RESUMO

Drug resistance patterns of shigella strains were investigated in a prospective manner in Etimesgut district during a period of 1 year. Thirty strains shigella were isolated, belonged to three subgroups with preponderance of Sh. flexneri (70%), followed by Sh. sonnei (27%) and Sh. boydii (3%). The resistance was highest with streptomycin (80%), followed by trimethoprim-sulfamethoxazole (TMP-SMZ) (53%) and ampicillin (43%). Only three strains (10%) were sensitive to all eight antibiotics tested. Sixteen (53%) were resistant to three or more antibiotics. The data showed an increase in resistance to the commonly used antimicrobial agents--namely IMP-SMZ and ampicillin. IMP-SMZ is no longer the drug of choice in severe shigellosis, at least in this region of Turkey.

RESUMO

The aim of this report is to emphasize that corticosteroids should not be prescribed when the etiological factors remain unidentified. A 34-year-old male visited our ophthalmology clinic suffering from blurred vision. Behçet's disease had been diagnosed 5 years prior, and the patient was taking an oral immunosuppressant and a systemic corticosteroid. Vitreous cell count and foci of chorioretinitis (apparently confined to the ocular fundus) were evident. A vitreous sample was subjected to polymerase chain reaction, which resulted in the identification of and Mycobacterium tuberculosis. Treatment with a combination of four anti-tuberculosis drugs was commenced. During the follow-up, the vitritis disappeared, and the foci of active chorioretinitis improved. Systemic and Sub-Tenon corticosteroid treatment should not be prescribed until vitreous and anterior chamber fluid samples have been evaluated in patients with uveitis. Some microbes are not detected on routine examination.

RESUMO

OBJECTIVES: Upper air obstruction leads hypoxia, it is also known that S-100B levels increase by glial activations indicate cerebral hypoxic injury. This study aimed to evaluate the preoperative and postoperative S-100B levels in children with chronic adenotonsillar hypertrophy. PATIENTS AND METHODS: The study comprised 40 patients with indications for tonsillectomy and/or adenoidectomy following a diagnosis of chronic adenotonsillar hypertrophy and 40 age-gender matched control patients. Blood samples were taken from the patients preoperatively and at four weeks postoperatively. Preoperative and postoperative serum S-100B levels were analyzed. RESULTS: The serum S-100B levels in the preoperative period were found to be significantly higher compared to those of the control group (p < 0.05). The S-100B levels were significantly decreased in the postoperative period (p < 0.05). CONCLUSIONS: The development of chronic adenotonsillar hypertrophy would play a role in increased S-100B levels. This indicates that neuronal damage would exists in patients with chronic adenotonsillar hypertrophy.
