RESUMO

OBJECTIVE: Tp-e interval and Tp-e/QTc are among the new-generation indicators used for predicting cardiac arrhythmia and ventricular repolarization. In this study, we aimed to evaluate Tp-e and Tp-e/QTc ratios in patients with overt hypothyroidism and subclinical hypothyroid patients. PATIENTS AND METHODS: In this study, a total of 105 patients were included with 35 overt hypothyroidism, 35 subclinical hypothyroidism, and 35 healthy euthyroid patients. The anthropometric measurements, laboratory results, and electrocardiographic data of the patients were measured. The groups were compared in terms of Tp-e interval, Tp-e/QT and Tp-e QT/c ratios. RESULTS: When the Tp-e interval and Tp-e/QTc values of the patients were compared, a significant difference was found (p<0.001). A positive correlation was found between thyroid stimulating hormone (TSH) with Tp-e interval and Tp-e/QT ratio. CONCLUSIONS: Tp-e interval and Tp-e/QTc duration increased in overt hypothyroidism and subclinical hypothyroidism patients compared to euthyroid patients. We believe that regular use of levothyroxine therapy in overt hypothyroidism patients will decrease cardiac mortality. Cardiac risk factors should be considered to decide on levothyroxine therapy for subclinical hypothyroidism patients.

RESUMO

Zoonoses are frequently associated with wild animals. Research on reptiles either living in their natural habitat or kept as pet animals has shown that these animals frequently serve as the asymptomatic hosts of bacterial zoonotic agents, including Salmonella spp. and Escherichia coli. Studies have shown the potential of reptiles to transmit these pathogens to humans and other animals. Epidemiological research on the herpetofauna of various regions has demonstrated the high potential of reptiles as a reservoir of Salmonella spp. In the present study, Salmonella spp. were not isolated or identified from the snake-eyed lizard. Out of 150 cloacal swab samples of snake-eyed lizard 25 (16.7%) E. coli were isolated and out of these 4 (2.7%) were identified to be E. coli O157:H7 by PCR. The results suggest that Ophisops elegans could be involved in the transmission of E. coli, rather than Salmonella spp. This study demonstrates for the first time that the snake-eyed lizard acts as a cloacal carrier of E. coli O157:H7 and presents data that may aid in preventing the transmission of this strain to humans.

RESUMO

OBJECTIVE: To examine the complication rate in adult patients during and after cochlear implantation. METHODS: A retrospective chart review was conducted of patients who had undergone cochlear implantation at a tertiary referral centre between 2009 and 2018. All complications and their treatments were categorised as either minor or major, as well as intra- or post-operative. RESULTS: The records of 392 patients with 395 implants were reviewed. The mean follow-up period was 89 ± 65.5 months (range, 6-408 months). The mean age of patients was 46 ± 15.2 years (range, 19-84 years). Sixty-two patients (16 per cent) had minor complications and 31 (8 per cent) had major complications. CONCLUSION: Although cochlear implantation has the potential for significant intra- and post-operative complications, the actual complication rate is relatively low, and it can therefore be considered a safe procedure.

RESUMO

PURPOSE: Familial Mediterranean fever (FMF) is an idiopathic disease with chronic inflammation. We aimed to determine the changes caused by the chronic inflammatory nature of FMF on the ocular surface, meibomian glands (MG), and conjunctiva via conjunctival impression cytology (CIC). MATERIAL-METHOD: Forty-two FMF patients with a mean age of 11.93±3.92 years and 36 control patients with a mean age of 11.83±3.38 years were included in the study. Ocular surface anomalies of the patients were evaluated using Schirmer II, TBUT and OSDI. MG function (meibum quality), morphology (meiboography), and CIC were evaluated. RESULTS: Although there was a significant difference between the groups in terms of Schirmer II and TBUT, OSDI scores did not significantly differ (P=0.022, 0.010, and 0.099 respectively), and no significant dry eye sign was observed in either group. There was significant difference between the groups in terms of the percent area of MG dropout, MG density, meiboscore (P=0.020, 0.023, and 0.031 respectively), but no significant difference was observed in relation to MG quality (P=0.650). Although conjunctival impression cytology was of a higher grade in the patients with FMF according to Nelson's classification, no significant difference was observed between the groups (P=0.109). CONCLUSION: Although there was a decrease in the number of MGs in FMF patients, no significant deterioration was observed in conjunctival cytology. In these patients, tear film stability may deteriorate in particular. Clinicians should be aware of the possibility of ocular surface disease secondary to MG dropout in patients with FMF.

RESUMO

We investigated the antioxidant effects of vitamin E on a glucocorticoid (GC) induced model of cataracts in chick embryos. We used 70 fertilized eggs divided into seven groups as follows: phosphate-buffered saline (PBS) group, olive oil treatment (OO) group, hydrocortisone treatment (HC) group, olive oil and hydrocortisone treatment (OO + HC) group, 50 mg/kg vitamin E and hydrocortisone treatment (HC + VE (50)) group, 25 mg/kg vitamin E and hydrocortisone treatment (HC + VE (25)) group and 15 mg/kg vitamin E and hydrocortisone treatment (HC + VE (15)) group. On day 17, chick embryos were removed from the eggs and lens and liver tissues were excised. Cataract formation was evaluated and total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA) and glutathione peroxidase (GPx) were measured in lens and liver tissues; MDA was measured only in liver. The lenses in the HC + VE (50) group exhibited significantly higher levels of GPx and TAS, and lower levels of TOS than for HC and OO + HC groups. The livers of the HC + VE (50) group exhibited significantly higher levels of GPx and lower levels of MDA than for the HC and OO + HC groups. The HC + VE (50) group lenses were evaluated as grade 1, because the nuclei were completely free of cataracts, likely due to the antioxidative effect of high dose VE. VE is an effective antioxidant agent that exhibits a dose-response effect, for ameliorating the negative effects of GCs.

RESUMO

BACKGROUND: Thyroid nodules are a common pathology worldwide. Fine needle aspiration biopsy (FNAB) is an important diagnostic method for the investigation of malignancy in thyroid nodules. However, according to the Bethesda System used to classify the results, patients with atypia of undetermined significance/follicular lesion of undetermined significance (AUS / FLUS) may not be classified as benign or malignant. Therefore, it may be necessary to determine some clinical risk factors to apply the best treatment in these patients. AIM: To determine the factors that increase the risk of malignancy in this patient group. METHODS: A retrospective study including 138 patients with an FNAB categorized as AUS/FLUS and operated between June 2015-September 2018. Demographical, Laboratory (TSH) and Ultrasound variables (number, size and characteristics of nodules) of the patients were compared among postoperative histopathological results. RESULTS: Hypo-echoic structure, microcalcification and irregular margin of the nodules were detected to be associated with malignancy in patients with FNAB results of AUS/FLUS (p <0.001). CONCLUSION: We suggest that surgical treatment should be considered if the patients have nodules with the hypo-echoic structure, microcalcification and irregular margin with an FNAB histopathological result of AUS / FLUS.

RESUMO

PURPOSE: Gossypol, a naturally occurring compound in cottonseeds, has anticancer effects against several tumor cell lines. It has been extensively studied in clinical trials and is well tolerated with a favorable safety profile. AT-101, a derivative of R (-)-gossypol, binds to Bcl-2 family proteins and induces apoptosis in vitro. Although transsphenoidal surgical excision of the pituitary corticotroph adenoma is the gold standard of care, it is not successful all the time. Medical therapy for Cushing's disease still remains a challenge for the clinicians. We aimed to investigate the cytotoxic and apoptotic effects of AT-101 in mouse pituitary corticotroph tumor AtT20 cells. METHODS: Cytotoxic effect of AT-101 was assessed by XTT cell viability assay. Apoptosis was shown by measuring DNA fragmentation and Caspase-3/7 activity. Changes in mRNA expressions of apoptosis-related genes were investigated by qPCR array after treatment with AT-101. ACTH was measured by ACTH-EIA Kit. RESULTS: AT-101 induced cytotoxicity and apoptosis in AtT20 cells. mRNA levels of pro-apoptotic genes such as TNFR-SF-10B, Bid, PYCARD, Caspase-8, Caspase-3, and Caspase-7 were induced by 2.0-, 1.5-, 1.7-, 1.5-, 1.6-, and 2-fold, respectively, in AtT20 cells by AT-101 treatment. Moreover, some of the anti-apoptotic genes such as BCL2L10, NAIP1, and PAK-7 were reduced by 2.1-, 2.3-, 4.0-fold, respectively, in AtT20 cells. AT-101 also decreased ACTH secretion significantly. CONCLUSION: AT-101 induces apoptosis in mouse pituitary corticotroph tumor cells.

RESUMO

We investigated the microscopic structure of transverse sections of the oculomotor, trochlear and abducens nerves of Arabian foals using stereological methods. Bilateral nerve pairs from 2-month-old female Arabian foals were analyzed. The tissues were embedded in plastic blocks, then 1 µm thick sections were cut and stained with osmium tetroxide and methylene blue-azure II. Stereology was performed using light microscopy. Morphometry showed that the right and left pairs of nerves were similar. The transverse sectional areas of the oculomotor, trochlear and abducens nerves were 1.93 ± 0.19 mm2, 0.32 ± 0.06 mm2 and 0.70 ± 0.08 mm2, respectively. The oculomotor nerve exhibited a significantly greater number of myelinated axons (16755 ± 1279) and trochlear (2656 ± 494) and the abducens nerves (4468 ± 447). The ratio of the axon diameter to myelinated nerve fiber diameter was 0.58, 0.55 and 0.55 for the oculomotor, trochlear and abducens nerves, respectively. Of the three nerves studied, the abducens nerve exhibited the greatest nerve fiber area, myelin area, nerve and axon diameters, and myelin thickness. The ratio of small myelinated nerve fibers was greatest in the oculomotor nerve.

RESUMO

In this study, morphological characteristics of the canary tongue were examined macroscopically and histologically besides using scanning electron microscopy. Furthermore, histochemical features of the lingual salivary glands of the canary were also examined. The results suggest that the tongue of the canary has an equilateral quadrangle shape is sloped towards the apex on its dorsal surface; where its sides are bounded by tall epithelial extensions. Additionally, histological examination showed that salivary glands were only present on the body of the tongue and there were no taste buds. However, the tongue has mechanical sen-sory cell groups in its subepithelial connective tissue. Histochemical examination, demonstrated that the salivary gland epithelial cells contained carbohydrates which were composed of acidic sialo-mucins.

RESUMO

AIMS: To compare intraocular pressure (IOP) measurements obtained with Goldmann applanation tonometery (GAT), dynamic contour tonometry (DCT), tonopen (TP), and ocular response analyzer (ORA), and to determine the influence of Amsler grade and central corneal thickness (CCT) on the IOP readings in eyes with keratoconus that are classified into four groups according to the Amsler-Krumeich classification. METHODS: All eyes with keratoconus were separated into four groups using Amsler-Krumeich classification for keratoconus. IOP was measured in 202 eyes of 202 patients with keratoconus using GAT, DCT, TP, and ORA. RESULTS: The IOP differences revealed no significant difference among the Amsler degree in the DCT and corneal-compensated IOP (IOPcc) measurements (P>0.05 for all). There was no statistically significant difference in terms of IOP differences between GAT and IOPcc (P>0.05), TP and Goldmann-correlated measure of IOP (IOPg; P>0.05) in the Amsler I, while the IOP measurements revealed significant difference among the measurements of the four different tonometers in the Amsler II, Amsler III, and Amsler IV (P<0.05 for all). CONCLUSIONS: There was no significant association between DCT IOP or IOPcc and CCT in eyes with keratoconus; no statistically significant difference was found between keratoconus stages and the control group in terms of the IOP analyzed with these two techniques. These two techniques may be the most stable in the measurement of IOP in different keratoconus stages. However, no IOP technique can be used interchangeably with other techniques in the follow-up of keratoconus patients.

RESUMO

The mammalian target of rapamycin (TOR) has been implicated in the control of different stressors, growth factors, nutrients and hormones, participating in the control of key cellular functions. Controlling this many pathways poses mTOR signalling as a potential new target in new treatment strategies for multiple cancer types. mTOR components could potentially mislocated in tumour cells, which could lead to activation of signalling pathway that should not be active. Therefore, we aimed to show localisation of mTOR signal proteins in testicular seminoma. Tumoural testicular tissues were obtained from 10 patients with unilateral classic seminoma undergoing to therapeutic orchidectomy and compared with control human testicular tissues. Upon immunohistochemical evaluation, we detected mTOR and p-mTOR (serine 2448), P70S6K, p-P70S6K, PKCalpha and p-PKCalpha, CD36 and MAPLC3 proteins in the cytoplasm of Sertoli cells in the seminiferous tubules. We also showed cytoplasmic perinuclear staining in seminoma cells. This study demonstrated the interaction of mTOR signalling pathway and testicular seminoma by showing intense cytoplasmic mTOR pathway proteins immunoreactivity in the seminoma, for the first time in humans. Therefore, we suggested that mTOR signalling components could create new clinical targets for treatment of testicular seminoma patients and male infertility in the future.

RESUMO

OBJECTIVES: The aim of this study was to investigate the elastic properties of the aorta and the myocardial performance index of the left ventricle (LV) in patients with lichen planus (LP). SUBJECTS AND METHODS: A total of 54 patients with LP and 50 controls were enrolled in the study. The 2 groups were well-matched regarding age, gender, body mass index, any smoking history, diabetes mellitus and systolic and diastolic blood pressure (SBP and DBP). The echocardiographic examination was performed on the study subjects and the controls. Aortic elasticity parameters and the myocardial performance index of the LV were calculated. The Student t test, the x03C7;2 test and multiple linear regression were used for the statistical analysis. RESULTS: Aortic strain (AS, 4.77 ± 1.81 vs. 8.95 ± 2.22; p < 0.001) and aortic distensibility (AD, 0.25 ± 0.009 vs. 0.42 ± 0.120; p < 0.001) were significantly lower, and aortic stiffness index ß (ASIß, 3.65 ± 1.03 vs. 2.70 ± 0.91; p < 0.001) was significantly higher in the LP group than in the controls. The myocardial performance index (Tei index) was significantly higher in the LP group than in the control group (p = 0.001). The duration of the LP was negatively correlated with AS (r = -0.364, p < 0.001) and AD (r = -0.279, p = 0.006), and positively correlated with the Tei index (r = 0.324, p = 0.001) and ASIß (r = 0.364, p < 0.001). After adjustment for relevant confounders (age, male gender, smoking, SBP, DBP, diabetes mellitus and low- and high-density lipoprotein cholesterol), LP and its duration were still associated with AS, AD and ASIß. CONCLUSION: In this study, AS and AD were lower and ASIß and myocardial performance index higher in LP patients than in controls.

RESUMO

BACKGROUND AND AIM: Sarcoidosis is a multi-systemic granulomatous disease of unknown etiology. The present study has been designed to evaluate the importance of diastolic dysfunction with left atrial volume index (LAVi) and left ventricular mass index (LVMi) in determining subclinical cardiac involvement in subjects with stage I-II pulmonary sarcoidosis. METHODS: A total of 54 patients under follow-up for sarcoidosis without cardiac involvement and 56 healthy subjects were included in the study. The echocardiographic assessment of the patients revealed no significant difference between the two groups regarding left ventricular end-systolic and end-diastolic diameters, ejection fraction (LVEF) and annular velocity determined by tissue Doppler evaluation. RESULTS: The LVEF calculated was 61.8 ± 7.8 % in the sarcoidosis group versus 64.1 ± 2.7 % in the control group (p = 0.04). Left ventricular interventricular septum thickness, posterior wall thickness, and relative wall thickness were significantly higher in the sarcoidosis group compared to the control group (p < 0.001). The sarcoidosis group had higher LVM and LVMi values compared to the control group (145 ± 18.1 and 79 ± 14 g/m(2), 135 ± 27.7 and 74 ± 14.2 g/m(2); p = 0.020 and p = 0.021, respectively). Left atrial end-systolic volume and LAVi were higher in the sarcoidosis group (28.7 ± 18.5; 15.6 ± 10.2) compared to the control group (16.6 ± 10.9; 8.9 ± 5.5) with a statistically significant difference (p < 0.001). CONCLUSION: The present study indicates diastolic dysfunction and increased LVMi despite normal systolic function in patients with early-stage sarcoidosis without cardiac involvement. Also, the diastolic parameters were normal without showing any significant difference compared to the control group while there was a statistically significant increase in LAVi. This finding suggests that LAVi may be the earliest marker of diastolic dysfunction in patients with early-stage sarcoidosis without cardiac involvement.

RESUMO

OBJECTIVES: The aim of this single-center study was to assess the incidence and predictors of in-hospital access site complications related to transcatheter aortic valve implantation (TAVI) performed with new delivery systems in our hospital which has the largest case series in Turkey. MATERIALS AND METHOD: We performed successful TAVI with the Edwards Sapien XT valve to 127 (46 male) patients via a transfemoral (121), trans-subclavian (5) and transapical (1) approach. Access site complications were defined according to the Valve Academic Research Consortium (VARC) end-point definitions. RESULTS: Vascular complications occurred in 10.1% of patients. There was negative correlation between vascular complications and diameter of the common femoral artery (r = - 0.301, p=0.004), external iliac artery (r = - 0.327, p=0.004) and common iliac artery (r = - 0.324, p=0.004), but positive correlation between diabetes (r =0.240, p=0.008), sheath to femoral artery ratio (SFAR), sheath to external iliac artery ratio (SEIAR), procedure time, discharge time and the Society of Thoracic Surgeons (STS) score (respectively; r=0.339, 0.001, 0.527, 0.361, 0.289, p=0.003, 0.001, 0.001, 0.001, 0.002). The incidence of vascular complications was significantly higher in patients with diabetes and a high STS score. VARC bleeding complications occurred in 11.7 % of patients. The learning curve pointing out the importance of experience was significantly important in decreasing both bleeding and vascular complications. CONCLUSIONS: In this study, we demonstrated that major vascular complications related to TAVI decrease with the use of smaller delivery systems and experience and increase with high-risk scores (STS) and the presence of diabetes. In addition, VARC major vascular complications, observed mostly in patients with diabete mellitus (DM) and high STS scores, were associated with vascular diameters. These results further underline the importance of experience and a multidisciplinary team in patient selection and management for TAVI.

RESUMO

BACKGROUND: The treatment of castrate-resistant prostate cancer (CRPC) still remains as an important challenge of daily oncology practice. Docetaxel significantly prolongs overall survival in men with CRPC. Thymoquinone (TQ), one of the flavonoid compounds isolated from Nigealla sativa, has been shown to possess cytotoxic activity against a variety of cancer cell lines. MATERIALS AND METHODS: The aim of the study was to investigate the possible synergistic cytotoxic/apoptotic effects of a novel combination, docetaxel and TQ in DU-145 hormone- and drug-refractory prostate cancer cells and their effects on PI3K and ERK signaling pathways. RESULTS: We observed that the combination of docetaxel and TQ resulted in a significant synergistic cytotoxicy and apoptosis as compared to any single agent alone, in a dose-dependent manner. It was found that viability of the combination treated cells was not significantly changed in the presence of LY294002 as compared to inhibitor treated cells. However, in the presence of FR180204, viability of combination treated cells was significantly decreased as compared to inhibitor treated cells. In conclusion, cytotoxic effect of the docetaxel and TQ combination is correlated with the block of the PI3K/Akt signaling pathway in DU-145 cells. CONCLUSION: Therefore, this combination strategy may be an alternative approach for the challenging era of daily oncologic practice. Also, the combination of docetaxel and TQ might allow a reduction in docetaxel doses and diminish adverse effects of docetaxel while maintaining the therapeutic effect in patients with CRPC.

RESUMO

AIM: Carotid revascularization is an established theurapeutic modality in preventing stroke and death among patients with severe carotid stenosis. Although carotid endarterectomy remains as the primary option, carotid stenting is accepted as an alternative for patients with high risk for carotid endarterectomy. Recently published reports have better results with proximal protection devices when compared with distal protection devices. These studies have revealed less microembolic signals and less periprocedural new ischemic lesions on diffusion weighted magnetic resonance imaging. Stent choice may be also important for these procedures as open cell stent design has advantage of better flexibility whereas closed cell systems have an advantage of better scaffolding. Hybrid stents which are composed of open cells in the proximal and distal part and closed cells in the middle may carry both advantages. The aim of this study is to demonstrate whether combination of proximal protection devices with hybrid stents can be a safe alternative for carotid stenting in terms of periprocedural and 30-day outcomes. METHODS: Here we retrospectively evaluated 68 symptomatic carotid stenosis patients undergoing carotid stenting with hybrid stent (Cristallo Ideale®, Invatec s.r.l., Medtronic, Italy) and proximal protection device (MO.MA®, Invatec s.r.l., Medtronic, Italy). RESULTS: Our results showed only 1 minor stroke in the periprocedural period and during the first 30-day after stenting, with no death or myocardial infarction. CONCLUSION: Although our case number is not large, we propose that carotid stenting may be safer with utilization of proximal protection system and hybrid type carotid stents.

RESUMO

AIM: We aimed to investigate the incidence and clinical relevance of incidental parathyroidectomy (IPT) following thyroid surgery. METHODS: A retrospective review of thyroid operations was performed between January 2013 and January 2014. Pathology and operative reports were analyzed to identify the specimens which included parathyroid tissue. Information related to diagnosis, operative details and postoperative complications were collected. Calcium levels of ≤8 mg/dL was defined as biochemical hypocalcemia and those presenting with classic findings of acute hypocalcemia, were classified as clinical hypocalcemia. RESULTS: Two hundred and forty-five thyroid procedures were performed during study period. IPT was found in 34 (13.8%) cases: 25 were benign and 9 were malignant. Parathyroid tissue was found intrathyroidal in 6 patients (17.6%); lobar locations were right lobe in 19 (55.8%) and left lobe in 13 (38.2%) and isthmus in 2 cases (5.8%). The frequency of biochemical and clinical hypocalcemia were 50% (N.=17) and 8.8% (N.=3), respectively. Neither surgical type (lobectomy or thyroidectomy) nor malignancy (benign or malign) was not found associated with biochemical hypocalcemia. In those with biochemical hypocalcemia, left location of both dominant nodule and extracted parathyroid gland were significantly higher (P=0.01 and 0.04, respectively). CONCLUSION: Incidental parathyroidectomy which is not uncommon (13.8%) after thyroidectomy is not associated with postoperative biochemical hypocalcemia. Neither the type of surgical procedure (lobectomy or thyroidectomy) nor the pathology but adjacent dominant nodule location may increase the risk of IPT.

RESUMO

Case Report. A 15-year-old boy presented to the Fatih Sultan Mehmet Education and Research Hospital with the complain of bilateral vision blurring associated with severe glare and photophobia. On ophthalmological examination, uncorrected visual acuity was 20/200 in the right eye and 20/100 in the left eye, and there was no improvement with pinhole testing. The slit-lamp examination showed persistent pupillary membranes (PPM) in both eyes. According to the history obtained from his parents, he had received cardiac surgery for tetralogy of Fallot (TOF) 8 years ago. Conclusion. This patient is unique because this is the first reported case of bilateral PPM with congenital heart anomaly in the literature. Bilaterality of the eye anomaly strengthens the possibility of an uncommon association between PPM and TOF, rather than local failure in embryonic development.
