RESUMEN
Summary: Background. Pediatric cutaneous mastocytosis patients diagnosed and followed up by our specialist were enrolled in this study, and clinical and laboratory evaluations were retrospectively analyzed from patients' archived files. Methods. Patients, who applied to the Division of Pediatric Allergy And Immunology Unit of a University Training and Research Hospital between 01.01.2010 and 28.04.2021, were enrolled in this study. Results. Of the 33 patients included in the study, 11 (33.3%) were female and 22 (67.7%) were male. The median age of onset of the patient's complaints was 7 (0-60) months. The median age at diagnosis was 11 (2-64) months. Their complaints' median regression age was 54 (6-192) months. Resistant clinical findings were followed in 13 (39.4%) patients. Itching, redness, gastrointestinal symptoms, and maculopapular eruption were the most common complaints. The rashes were mostly polymorphic and larger than 1 cm. Heat was the most common trigger. Darier's sign was positive in 97% of the patients. Antihistamines were the most commonly used drug for prophylaxis and treatment. The autoinjector prescription rate was 24.2%. Conclusions. Quality of life was mildly affected in 48,5% of the patients based on the CDLQI scores. Thus, patients should be followed up through adolescence for the development of systemic signs and symptoms.
RESUMEN
OBJECTIVE: The aim of this prospective cross-sectional study was to investigate whether cleaning the episiotomy line with rifampicin solution before suturing will reduce infection and wound dehiscence in women who had vaginal delivery with episiotomy. PATIENTS AND METHODS: A prospective cross-sectional study was conducted with a total of 400 primigravida patients. In the study group, irrigation with rifampicin of the subcutaneous tissue of the episiotomy incision was applied, and in the control group, there was no irrigation. Patients were evaluated for infection at the 1st, 3rd week, and 1-month controls. The groups were compared according to episiotomy infection and wound dehiscence rates. RESULTS: The episiotomy infection rate of the whole group was 8.5%, the wound dehiscence rate was 3.75%, and the average time of occurrence of the infection was 5.35±2.21 days. The most common infection findings were local pain and purulent discharge at 4.75%. In the control group, where the infection occurred earlier, the infection and wound dehiscence rates were significantly higher [11.5% vs. 5.5%; 6.0% vs. 1.5% (p<0.05)]. Purulent discharge was the most common finding in the control group, and local pain in the study group, but no significant difference was found between the two groups in terms of findings (p<0.05). When only the patients who developed episiotomy infection were evaluated among themselves, the only significant difference was found in wound dehiscence, which was higher in the control group (p<0.05). CONCLUSIONS: Considering the high rates of episiotomy in our country, subcutaneous irrigation with rifampicin is a good option that can be kept in the foreground due to its low cost and ease of application.

Background and Aim: This experimental study aimed to investigate the reliability of using electronic apex locator devices to determine the working length of artificial root canals. Materials and Methods: The experiments were performed using resin endoblocks and mandibular canine teeth (n = 20/group). After the same working length of root canal samples was provided, the teeth and artificial root canals were embedded in an alginate mold. The measurements with Root ZX® and Propex Pixi® apex locators were performed and recorded. The data were analyzed using SPSS software (SPSS V23; IBM Corp., Armonk, New York, USA) and the variance was set at P < 0.05. Results: There was no significant difference between the groups; mean distance from the actual working length using different apex locators (P = 0.633, P = 0.474), and endpoint positioning distributions (P = 0.591). Conclusion: The results indicate that the artificial model could be a laboratory method of determining the accuracy of apex locators and efficient calibration of devices before their clinical use.

Background: One of the most important complications of diabetes mellitus (DM) is vision loss due to diabetic retinopathy (DR). Optical coherence tomography (OCT) provides visualization of early structural abnormalities of the retina and choroid. Aim: To compare retinal thickness (RT) and choroidal thickness (CT) between patients with DM without DR and healthy controls. Patients and Methods: Diabetic patients without DR were divided into two groups according to serum glycosylated hemoglobin (HbA1c) levels. Group 1: HbA1c ≤7.5 (n = 25) and group 2: HbA1c >7.5 (n = 23). The 3rd group was the healthy control group (n = 25). CT and RT measured by OCT were compared between the three groups. Results: CT in the subfoveal, temporal, and nasal quadrants was significantly higher in the healthy control group than in groups 1 and 2. Subfoveal and temporal quadrant CT in group 2 were significantly thinner than those in group 1. The average RT (ART) was thinner in group 1 than in the other groups, but there was no difference between the control group and group 2. Conclusions: This study showed that CT and ART decreased in diabetic patients without DR.

BACKGROUND: To determine the frequency of sodium hypochlorite (NaOCl) extrusion and evaluate the outcome of the injury. METHODS: A total of 1123 teeth indicated root canal treatment were included. An open-ended needle was used during/after the instrumentation. Acute burning pain during irrigation was considered as NaOCl extrusion. Negative aspiration was applied for patients with extrusion, and appropriate treatment was planned due to the symptoms. The number of patients who experienced extrusion and symptoms were recorded. Analysis of variance (ANOVA), at P < 0.05, was used to compare the data groups. RESULTS: NaOCl extrusion rate was found at 0.89%, and the injury with swelling that differential diagnosis of NaOCl accident caused by extrusion rate was 0.18%. The most common findings besides acute pain, as a sign of extrusion (n = 10), were accompanying apical bleeding (n = 6) and swelling (n = 2). According to the number of visits, a significant correlation was found between the symptoms (P = 0.010). No serious injury such as a neurological sign, tissue necrosis or trismus occurred in any patient. CONCLUSIONS: Demographic characteristics of the patients and preoperative condition of teeth were not related to NaOCl extrusion. The increasing number of visits may affect the probability of an accident. Negative aspiration immediately may be crucial in preventing severe injuries.

1. Aflatoxins (AFs) are metabolites which especially have toxic effects on proteins, and are detoxified by the aflatoxin-B1 aldehyde reductase (AFAR) pathway. In this pathway, the aldo-keto reductase family 7, member A2 (AKR7A2) enzyme, which is controlled by nucleic-related erythroid factor 2 (Nrf2), plays an active role. However, data on the efficacy of this critical pathway in broilers is limited.2. The aim of the following study was to investigate the changes in the expression levels of AKR7A2, Nrf2, and caspase-3, and the effects of Nigella sativa seeds (NS), thymoquinone (TMQ), and bentonite (BNT) in broilers exposed to AFs.3. One-hundred broilers were divided into ten groups (control (CNT); AF; NS; TMQ; BNT; AF+TMQ; AF+NS; AF+BNT; AF+BNT+NS; AF+BNT+TMQ) and fed for 28 d. AF, TMQ, NS and BNT were added to diets at levels of 2 mg/kg, 300 mg/kg, 50 g/kg and 10 g/kg respectively.4. The addition of AF to the diet decreased AKR7A2 and Nrf2 levels dramatically, but increased caspase-3 (P < 0.01). TMQ, NS and BNT additions to the diet eliminated all negative effects caused by AF (P < 0.01); and AKR7A2 and Nrf2 were further raised in TMQ and NS groups when compared to the control group. TMQ and NS showed a positive effect on detoxification parameters when given together with BNT.5. Supplementation with NS and TMQ enhanced AF detoxification via the AFAR pathway, by increasing AKR7A2 and Nrf2 levels, in addition to reducing hepatocyte apoptosis.

BACKGROUND: Early onset bacterial sepsis in neonates (EOS) is recognized as an important health condition. Early diagnosis is crucial. However, blood culture results are released in 48-72 hours. Many biomarkers have been investigated but none have been accepted as the gold standard. This study aimed to investigate the diagnostic value of the molecules: soluble form of triggering receptor expressed on myeloid cells-1 (sTREM-1), pentraxin-3 (PTX-3) and pro adrenomedullin (pro-ADM) in EOS and compare with currently used biomarkers. METHODS: In this multicenter prospective study, patients were enrolled from different NICUs around the Turkey. Patient data were collected via web-based registry system from attending centers. Neonates, hospitalized with a suspicion of EOS were enrolled. Blood culture and routine blood tests were collected and a serum sample was obtained and kept in - 80°C for studying the molecules. According to laboratory results, patients were divided into three groups as; proven sepsis, clinical sepsis and control group. Groups were compared in terms of demographic, clinical and laboratory findings. The primary outcome of the study was to assess any difference between groups in terms of the diagnostic value of the markers aforementioned. RESULTS: A total of 130 patients were enrolled; proven sepsis (nâ=â36), clinical sepsis (nâ=â53) and control (nâ=â41) groups. Groups were similar in terms of demographic findings; mean WBC (Pâ=â0.445), procalcitonin (PCT) (Pâ=â0.083) and IL-6 (Pâ=â0.814) levels. Mean C-reactive protein (CRP) level was significantly higher in clinical sepsis and proven sepsis groups compared to control group (Pâ<â0.001). Mean PTX-3 (Pâ=â0.547), pro-ADM (Pâ=â0.766) and sTREM-1 (Pâ=â0.838) levels were similar between groups. CONCLUSION: These promising molecules failed to help in early diagnosis of EOS. Their relation to correlation with disease progression may make more sense as they seem to be expressed in higher amounts with the progression of the disease in previous studies. CRP was the most frequently used biomarker for detecting the sepsis in our study population.

BACKGROUND: Linagliptin (LNG) is a selective dipeptidyl peptidase-4 (DPP-4) inhibitor that ameliorates blood glucose control of patients with type 2 diabetes, without developing hypoglycemic risk and weight gain with a good clinical and biological tolerance profile. To the best of our knowledge, its cytotoxic, genotoxic and oxidative effects have never been studied on any cell line. AIM: To evaluate the in vitro cytotoxic, genotoxic damage potential and antioxidant/oxidant activity of LNG in cultured peripheral blood mononuclear cells (PBMC). MATERIAL AND METHODS: After exposure to different doses (from 0.5 to 500 mg/L) of LNG, cell viability was measured by the MTT (3,(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and lactate dehydrogenase (LDH) leakage tests. The antioxidant activity was assessed by the total antioxidant capacity (TAC) and total oxidative stress (TOS) assays. To evaluate the genotoxic damage potential, chromosomal aberration (CA) frequencies and 8-oxo-2'-deoxyguanosine (8-oxo-dG) levels were determined. RESULTS: Treatment with LNG did not cause statistically significant decreases of cell viability at lower concentrations than 100 mg/L as compared to untreated cultures. However, LNG exhibited cytotoxic action at 250 and 500 mg/L. Also, IC20 and IC50 values of LNG were determined as 8.827 and 70.307 mg/L, respectively. In addition, the oxidative analysis revealed that LNG supported antioxidant capacity at concentrations of 2.5, 5, 10, 25, 50 and 100 mg/L without generating oxidative stress. Besides, the results of CA and 8-oxo-dG assays showed in vitro non-genotoxic feature of LNG. As a conclusion, our findings clearly revealed that LNG had no cytotoxic and genotoxic actions, but exhibited antioxidative activity. In conclusion, therefore it is suggested that LNG use in diabetic patients is safe and provides protection against diabetic vascular and oxidative complications.
RESUMEN
In this study, the effect of ultrasound (US) on the quartz-amine flotation system was investigated in detail by considering various surface chemistry techniques. The effect of ultrasound on particle size, shape factor, and surface roughness were characterized by using Brunauer-Emmett-Teller (BET) surface area measurements and scanning electron microscopy (SEM) analyses. The contact angle and bubble-particle attachment time, as well as adsorption density measurements was carried out to evaluate the effect of ultrasound on quartz surface wetting ability. In addition, atomic force microscopy (AFM) analyses were conducted, and finally micro-flotation studies were performed. As a result, it was found that the micro-flotation recovery at 2â¯×â¯10-5â¯M dodecyl amine hydrochloride (DAH) concentration increased from 45.45% to 63.64% with 30â¯W ultrasonic application at conditioning step. However, the micro-flotation recovery decreased to 37.50% when the ultrasonic power increased to 150â¯W. The results showed some effect of ultrasound on particle size, particle shape, and surface roughness in some extent. The increase in the contact angle and the decrease in the bubble-particle attachment time were observed. A slightly high adsorption density was measured. All these show a positive effect of ultrasound on quartz flotation with amine as a collector.
RESUMEN
AIM: To compare the incidence, intensity and prediction of postoperative pain after glide path preparation with manual, continuous rotary and a novel reciprocating glide path instrument. METHODOLOGY: The study included 240 patients, who were treated by four specialists according to a planned treatment protocol. Following access cavity preparation and prior to glide path preparation, the subjects were randomly assigned to one of the three groups according to the glide path instrument by choosing a sealed envelope containing the group name: R-Pilot (VDW, Munich, Germany), ProGlider (Dentsply Sirona, Ballaigues, Switzerland) and stainless steel K-files (Dentsply Sirona; n = 80). Following glide path preparation, the teeth underwent standardized single visit root canal treatment procedures. The root canals were chemomechanically prepared using the ProTaper Next rotary system (Dentsply Sirona) under copious irrigation with 5.25% NaOCl. Final irrigation was performed with 17% EDTA and distilled water. Root fillings were placed using an epoxy resin sealer and gutta-percha with a cold lateral compaction technique. After coronal restorations were placed, the patients were discharged with a questionnaire about the incidence and intensity of pain at 6, 12, 18, 24, 48 and 72 h postoperatively. The data were analysed using chi-square, anova and Tukey tests and logistic regression analysis. RESULTS: The presence of preoperative pain (OR ranged between 3.5 and 14.3) and the glide path preparation techniques (OR between 2.2 and 4.1) were associated with significant effects on the incidence of postoperative pain when comparing manual versus engine-driven glide path preparation (P < 0.05). Patients in the R-Pilot (Mean VAS ranged between 1.57-0.21) and ProGlider (1.97-0.28) groups reported significantly less postoperative pain scores than those in the manual group (2.82-1.32; P < 0.05). There was no significant difference between R-Pilot and ProGlider groups regarding the postoperative pain scores (P > 0.05). CONCLUSION: Preparation of glide paths with rotating or reciprocating NiTi instruments was associated with less postoperative pain levels and incidence compared to manual glide path preparation with no significant difference between rotating and reciprocating instruments. Preoperative pain was the most significant predictor for the occurrence of postoperative pain.

PURPOSE: In this study, we aimed to describe the real-life practice outcomes of pertuzumab-trastuzumab-taxane (PTT) combination in visceral organ metastatic, trastuzumab-naive breast cancer (BC) patients. METHODS: This study was conducted by Turkish Oncology Group and included 317 patients' data from 36 centers. RESULTS: Median age was 51 (22-82). Median PFS was 28.5 months, while median OS was 40.3 months. Patients with brain metastases (n: 13, 4.1%) had worse PFS (16.8 m vs. 28.5 m; p = 0.002) and OS (26.7 m vs. 40.3 m; p = 0.009). Patients older than 65 years of age (n: 42, 13.2%) had significantly lower OS results (19.8 m vs. 40.3 m; p = 0.01). Two hundred sixty-eight patients (86.7%) received docetaxel while 37 patients (11.7%) received paclitaxel. PFS and OS were similar between taxane groups. In eight patients (2.5%), 5-40% ejection fraction decrement from baseline was detected without any clinical sign of heart failure. CONCLUSIONS: Our RLP trial included only visceral metastatic, trastuzumab-naïve BC patients including cases with brain involvement who received PTT combination in the first-line treatment. Regardless of negative prognostic characteristics, our results are in parallel with pivotal trial. Further strategies for brain metastasis should be developed to improve outcomes despite encouraging results with PTT treatment. Taxane selection can be personalized and endocrine maintenance may further improve outcomes after taxanes were discontinued. To our knowledge, this is the largest scale real-life clinical practice study of pertuzumab-trastuzumab-taxane therapy to date.

In this study, the effect of the supplemental organic chromium (Cr) forms on the expression of ovarian orexin(hypocretin), glucose transporters (GLUTs), heat shock proteins (HSPs) andnuclear factor-kappaB (NF-κB)were investigated in laying hens (HS). Laying hens (n=1800; 16-wk-old; Lohmann LSL-Lite) were allocated to 6 random groups according to a 2 × 3 factorial trial scheme with two different environmental temperatures [Thermoneutral (TN groups; at either 22±2 °C 24 h/d) and heat stress (HS groups; at 34±2 °C for 8 h/d, 08:00 to 17:00 h, followed by 22°C for 16 h for a period of 12 wks)], andhens reared under both environmental conditions were fed either a basal diet or the basal diet supplemented with 1.600 mg of chromium-picolinate (CrPic, 12.43% Cr) and 0.788 mg of chromium-histidinate (CrHis, 25.22% Cr) per kg of diet, delivering 200 µg elemental Cr per kg diet. HS groups showed decreased levels of orexin and GLUTs(GLUT1, GLUT4), and increased NFκB, HSP60, HSP70 and HSP90 levels compared to the TN groups in ovarian tissue of hens (P < 0.0001 for all).However, dietary chromium supplementation (CrPic-CrHis) increasedorexin and GLUTs levels and significantly reduced the NF-κB and HSPs levels making them closer to those of thermoneutral group (P < 0.0001).In conclusion, CrPic and CrHis showed supported the relief and treatment of stress complications.

Hypothesis: Circumference measurement of extremities that was reported to be a reliable method as long as being standardized is commonly used both in clinical and home settings by clinicians or caregivers due to its cheapness and easy use. Objectives: The aims of this study were to determine the inter-observer and intra-observer reliability of manual circumference measurement among different observers and various measurement points. Methods and Results: A total of 58 lower limbs were included in the study. Both lower limbs of each subject were assessed by 6 observers randomly using circumference measurement method from 9 reference points specified with a Leg-O-Meter. All observers performed the measurements and they were blind to each other's measurements. Results: Measurement results from reference points were statistically significant between good to perfect (ICC 0.65-0.99, p<0.001). Interrater reliability of all observers' first and second measurements showed perfect reliability for both measurements (ICC: 0.92-0.99, p<0.001). Conclusions: This study demonstrated that the lower extremity manual circumference measurement is a reliable method for clinical practice.

SYNE1 related autosomal recessive cerebellar ataxia type 1 (ARCA1) is a late-onset cerebellar ataxia with slow progression originally demonstrated in French-Canadian populations of Quebec, Canada. Nevertheless, recent studies on SYNE1 ataxia have conveyed the condition from a geographically limited pure cerebellar recessive ataxia to a complex multisystem phenotype that is relatively common on the global scale. To determine the underlying genetic cause of the ataxia phenotype in a consanguineous family from Turkey presenting with very slow progressive cerebellar symptoms including dysarthria, dysmetria, and gait ataxia, we performed SNP-based linkage analysis in the family along with whole exome sequencing (WES) in two affected siblings. We identified a homozygous variant in SYNE1 (NM_033071.3: c.13086delC; p.His4362GlnfsX2) in all four affected siblings. This variant presented herein has originally been associated with only pure ataxia in a single case. We thus present segregation and phenotypic manifestations of this variant in four affected family members and further extend the pure ataxia phenotype with upper motor neuron involvement and peripheral neuropathy. Our findings in turn established a precise molecular diagnosis in this family, demonstrating the use of WES combined with linkage analysis in families as a powerful tool for establishing a quick and precise genetic diagnosis of complex neurological phenotypes.
