Investigation of the Mesiodistal Angulations of Maxillary Canines and Central Incisors for Missing Bilateral Maxillary Lateral Incisor. J Clin Med 2024; 13:2110. [PMID: 38610875 PMCID: PMC11012414 DOI: 10.3390/jcm13072110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 03/27/2024] [Accepted: 04/03/2024] [Indexed: 04/14/2024] Open
Abstract
(1) Background: A missing bilateral maxillary lateral incisor (MBMLI) causes aesthetic and functional problems and a multidisciplinary approach is required for treatment. This study aimed to compare the changes in the mesiodistal axial angulations of the maxillary canines and central incisors with orthodontic treatment of MBMLI. (2) Methods: A total of 56 patients with MBMLI were included in the study, and three groups were formed: the control group (Group 1, n = 20) with untreated ideal occlusion and the space opening (Group 2, n = 20) and space closure (Group 3, n = 16) groups as treated study groups. The mesiodistal angulations between the long axes of the maxillary right canine (tooth no 13), right central incisor (tooth no 11), left central incisor (tooth no 21) and maxillary left canine (tooth no 23), and the bicondylar plane, were measured on the panoramic radiographs taken pre (T0) and post treatment (T1). p < 0.05 was accepted for statistical significance. (3) Results: At T0, while there was no significant difference between the mesiodistal angulations of the right-left maxillary canines and central incisors in all groups (p > 0.05), the mesiodistal angulations of the canines in the Group 1 were significantly higher than the study groups (p < 0.05). With treatment, while the mesiodistal angulation of the canines increased in Group 2, it decreased in Group 3 (p < 0.05). On the other hand, the mesiodistal angulation of the central incisors decreased in Group 2 and did not change in Group 3 (p > 0.05). At T1, the mesiodistal angulation of the canines was found to be lower in Group 3 than in Groups 1 and 2, while the angulation of the central incisors was found to be lower in Group 2 compared to Group 1 (p < 0.05). (4) Conclusions: In the orthodontic treatment of MBMLIs, changes in the mesiodistal angulations of the maxillary canine and central incisors should be taken into account for satisfactory outcomes. It was concluded that there should be a tendency to select the space closure method in which normal mesiodistal angulations are obtained in maxillary central incisors for aesthetics and planned incisor position, and also at a low cost.

Chitosan-based films grafted with citrus waste-derived antifungal agents: An innovative and sustainable approach to enhance post-harvest preservation of citrus fruit. Int J Biol Macromol 2024; 264:130514. [PMID: 38423440 DOI: 10.1016/j.ijbiomac.2024.130514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 02/15/2024] [Accepted: 02/26/2024] [Indexed: 03/02/2024]
Abstract
This paper reports the synthesis, characterization, and properties of chitosan films (CHI) grafted with a natural antifungal agent with the aim of developing active films of natural origin to prevent post-harvest losses of citrus fruit. The antifungal agent was prepared by fermentation using lemon peel (AntiFun-LM), a citrus waste, and grafted on chitosan using different coupling agents (CHI/AntiFun-LM). Bioactive films were prepared by solvent casting. FTIR-ATR and ToF-SIMS analyses provided compelling evidence of the successful grafting process. TGA-DSC demonstrated that the films are stable after grafting. SEM studies showed the continuous and compact surface of the films. WCA measurements proved that CHI/AntiFun-LM films are more hydrophilic than CHI films. Moreover, the CHI/AntiFun-LM films showed stronger UV shielding effect when compared to CHI. The biological evaluation demonstrated that CHI/AntiFun-LM films gained considerable antifungal properties against most fungi responsible for post-harvest decay. Cytotoxicity tests showed that CHI/AntiFun-LM films did not cause any toxic effect against L929 fibroblasts. This study highlights the great potential of chemical grafting of antifungal agents produced from citrus waste to chitosan and preparation of natural-based films to act as a powerful alternative in post-harvest protection of citrus fruit in a perspective of circular economy.

Abstract
The purpose of this study was to examine the factorial invariance of the ASIS (Anadolu Sak Intelligence Scale) across gender. Raw scores from the ASIS standardization study ( N = 4641) were used in the analyses. Factorial invariance was analyzed by gender across three age groups: 4–7 ( N = 2528), 8–9 ( N = 848), and 10–12 ( N = 1265) using the Multisample Confirmatory Factor Analysis. Six models were developed from unconstrained to more constrained to test the factorial invariance. Each model tested one hypothesis. The findings showed that the second-order g model of the ASIS was invariant in all age groups. In addition, the first-order and second-order factor loadings and g variance were invariant across gender. A partial subtest intercept invariance was found for ages 4–7. Findings imply that ASIS factor scores mean the same latent variable for boys and girls in different age groups.

Design, Synthesis, and Evaluation of Novel Pyruvate Dehydrogenase Kinase Inhibitors. Med Chem 2023; 19:276-296. [PMID: 35986548 DOI: 10.2174/1573406418666220819102627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 06/02/2022] [Accepted: 06/10/2022] [Indexed: 11/22/2022]
Abstract
AIMS The present work describes the synthesis and the biological evaluation of novel compounds acting as pyruvate dehydrogenase kinase (PDK) inhibitors. These drugs should become a new therapeutic approach for the treatment of pathologies improved by the control of the blood lactate level. METHODS Four series of compounds belonging to N-(4-(N-alkyl/aralkylsulfamoyl)phenyl)-2- methylpropanamides and 1,2,4-benzothiadiazine 1,1-dioxides were prepared and evaluated as PDK inhibitors. RESULTS The newly synthesized N-(4-(N-alkyl/aralkylsulfamoyl)phenyl)-2-methylpropanamides structurally related to previously reported reference compounds 4 and 5 were found to be potent PDK inhibitors (i.e. 10d: IC50 = 41 nM). 1,2,4-Benzothiadiazine 1,1-dioxides carrying a (methyl/ trifluoromethyl)-propanamide moiety at the 6-position were also designed as conformationally restricted ring-closed analogues of N-(4-(N-alkyl/aralkylsulfamoyl)phenyl)-2-hydroxy-2-methylpropanamides. Most of them were found to be less potent than their ring-opened analogues. Interestingly, the best choice of hydrocarbon side chain at the 4-position was the benzyl chain, providing 11c (IC50 = 3.6 μM) belonging to "unsaturated" 1,2,4-benzothiadiazine 1,1-dioxides, and 12c (IC50 = 0.5 μM) belonging to "saturated' 1,2,4-benzothiadiazine 1,1-dioxides. CONCLUSION This work showed that ring-closed analogues of N-(4-(N-alkyl/aralkylsulfamoyl) phenyl)- 2-hydroxy-2-methylpropanamides were less active as PDK inhibitors than their corresponding ring-opened analogues. However, the introduction of a bulkier substituent at the 4-position of the 1,2,4-benzothiadiazine 1,1-dioxide core structure, such as a benzyl or a phenethyl side chain, was allowed, opening the way to the design of new inhibitors with improved PDK inhibitory activity.

Abstract
Oil yield and the properties of oil can be improved with various enzymatic pre-treatments before obtaining oil from oilseeds by cold-press extraction. A commercial mixture of pectolytic enzymes was used in this study. In addition, apple seed meal as a source of β-glucosidase enzyme and citric acid were applied to oilseeds (pumpkin, terebinth and flaxseed) as pre-treatments. The results were evaluated by comparing the effects of the pre-treatments on oil yield and properties. Enzyme preparate could increase the oil yield of pumpkin seeds (~300%) and flaxseed (151%). Significant increases in the phenolic contents of terebinth (from 91.67 to 319.33 mg GAE/kg) and flaxseed oils (from 12.03 to 40.47 mg GAE/kg) were achieved by citric acid and enzymatic pre-treatments. These two pre-treatments were also effective in terms of peroxide formation and oxidative stability in terebinth oil. With the help of the pre-treatments applied to oilseeds it was possible to increase the transition of phenolics from seeds to oil for terebinth oil with increase ratios of 245% for citric acid, 248% for the enzymatic process compared to the control.

Abstract
A commercial enzyme preparation consisting of pectolytic, cellulotic and hemicellulotic enzymes was applied to the oil extraction by cold pressing from apricot kernel, flaxseed and grape seed. The effects of enzyme pre-treatment varied depending on the different oil seed used as raw material. Although the increase in free fatty acidity can be considered as a negative effect (from 0.37 to 0.52), the decrease in peroxide number and p-anisidine values, increase in oil yield (22.75%), higher levels of total carotenoids and tocopherols, as well as a remarkable increase in phenolic content (x1.68) and radical scavenging effect (including hydrophilic and lipophilic-induced and total antioxidant capacity) showed that the use of enzyme application in the cold pressing of apricot kernel oil would be beneficial. Many of these positive results could not be achieved in the pressing of flaxseed or grape seed oils under the same conditions. A high negative correlation (r=-92.2) was found between p-anisidine value and δ-tocopherol for grapeseed oil. Hydrophilic and lipophilic antioxidant capacity, total phenolics, and total carotenoids negatively correlated well (r values above 80) with peroxide values for apricot seed oil. Correlation results showed that carotenoids play an important role in the oxidative stability of the oils, where it was much more evident for apricot seed oil (r=-97.5).

Abstract
Background:Serum autoantibodies closely reflect patterns of organ involvement and disease progression in systemic sclerosis (SSc). The entire autoantibody profile is less well defined in many cohorts and the data regarding their clinical associations and frequencies is limited.Objectives:To determine the autoantibody profile of patients with SSc, as well as their clinical associations, in well-characterized inception- cohort with disease duration less than 3 years.Methods:Serum samples of 100 patients out of 105 enrolled in the study were analyzed for ANA patterns with indirect immunofluorescence (IIF) assay using HEp-20-10/primate liver mosaic IIFT kit. Sera of 96 patients were subjected to commercial line immunoassay to quantify autoantibodies against 13 different autoantigens.Results:92 (92%) out of 100 patients were positive for ANA by IIF (Table 1). The speckled staining was the most pattern followed by nucleolar in 10 patients, centromere in 4, reticular in 1, nuclear in 2 and homogenous in 1. All patients (n= 96) patients were positive for at least 1 autoantibody by immunoblotting (Table 2). Twenty-two (49%) of patients with antiTopo I, 12 (44%) of the patients with antiCENP and 4 (22%) of the patients with antiRNAPIII were single positive. There was no difference in terms of the clinical findings when the patients with single and coexpression of these antibodies were compared. The distributions of the most frequent autoantibodies are shown in Figure 1. Interstitial lung disease was more frequent in the patients positive for anti-Topo I (78.8%) and anti-RNAPIII (27.3%). One of the two patients with breast cancer was anti-RNAPIII positive and none of the patients have diagnosed scleroderma renal crisis. Anti-Topo I was more common in patients with dcSSc (75%) and anti-CENP in lcSSc (46.4%).Table 1.Demographic, clinical and laboratory characteristics of the SSc patients.Sex Female N, %91 (86.7%) Male N, %14 (13.3) Female-to-male ratioAge, mean±SD years48.6±12.7Disease duration, mean±SD years2±1.4Disease classification N, % Diffuse39 (36.5%) Limited65 (62.5%) Sine scleroderma1 (1%)Interstitial lung disease37 (34.3%)Pulmonary arterial hypertension3 (2.8%)Scleroderma renal crisis0Digital ulcer14 (13.3%)Raynaud phenomenon105(100%)Telengiectasia31 (28.8%)Calcinosis1 (1%)Malignancy3 (2.9%)Antinuclear antibody profile N*, % Positive92 (92%)Staining pattern Speckled65 (65%) Nucleolar13 (13%) Centromere29 (29%) Homogeneous3 (3%) Reticular3 (3%)Table 2.Numbers and combinations of autoantibodies identified in the 96 SSc patients.Topo-ICENPRNAP IIIFibrillarinNOR90Th/ToPm/SclKuPDGFRRo52Topo-I22170159507CENP12202222011RNAPIII40121307Fibrillarin0000000NOR90011002Th/To04202Pm/Scl4306Ku102PDGFR00Ro522Single positive221240004102Total452718058179024Figure 1.Diagram of disease-related antibodies against the four main autoantibodies [anti-centromere (antiCENP) anti-Topoisomerase I (antiTopo I), anti-RNA polymerase III (antiRNAP III) and anti-Ro52).Conclusion:We presented the clinical and serologic features of the Turkish SSc patients from a new inception cohort.

Abstract
Background Female genital mutilation/cutting (FGM/C) is an illegal tradition commonly practiced in Sub-Saharan Africa and the Middle East. Despite a globalized world and developing social media, this harmful practice is currently still being implemented. Aims We aimed to evaluate the opinions of university students regarding FGM/C. Methods This descriptive study included 821 students who studied at Nyala University, Sudan, in January 2016. The students were questioned for the following: age, faculty, reasons for female circumcision, effects of female circumcision on female sexual functions and their views about the circumcision for their daughter. Results The rate of FGM/C among female university students was 80.1%. Although 73% of the male students prefer to marry uncircumcised women, they also reported that FGM/C should be continued to be performed, and their future daughters should be circumcised (64.5%). Female students were against FGM/C for their future daughters (77.6%). Conclusions This study shows that even educated individuals demand FGM/C in spite of knowing the harm. It is therefore suggested continuing educational studies on this subject.

Abstract
Light interaction with disordered materials is both complex and fascinating at the same time. Here, we reveal disorder-induced phase transitions in a dielectric Huygens' metasurface made from silicon nanocylinders that simultaneously support an electric and magnetic dipole resonance. Depending on the degree of positional disorder and the spectral detuning of the two resonances, the phase angle of the transmission coefficient exhibits a clear phase transition from normal to anomalous dispersion. Combined with the considerations of whether the resonances of spectrally detuned particles appear as separated or overlapping, we distinguish four different phase states. We study this phenomenon analytically by employing dipole particles and disclose the entire phase diagram, support our insights with full-wave simulations of actual structures, and corroborate the findings with experimental results. Unveiling this phenomenon is a milestone simultaneously in the growing fields of metamaterial-inspired silicon nanophotonics, photonics in disordered media, and the fundamental physics of phase transitions.

Abstract
Ranitidine is a H2 receptor blocker and rarely cause bradycardia. A 28 years old male patient attended the emergency department for urticaria. He was given 45 mg of phenyramine and 50 mg of ranitidine intravenously. He then complained of dizziness and developed bradycardia and hypotension. Electrocardiogram detected junctional bradycardia rhythm. He was given 0.5 mg atropine intravenously and his rhythm then returned to normal. His symptoms subsided and the blood pressure improved. Ranitidine is a frequently used medication and this case illustrated a rare but serious side-effect of the medication.

Abstract
AIM To determine the effect of photon-initiated photoacoustic streaming (PIPS) on the extrusion of debris using multiple-file (ProTaper Next-PTN) and single-file (One Shape-OS) continuous rotary systems in curved canals in human molar teeth. METHODOLOGY Sixty extracted maxillary first molar teeth with curved mesial roots, mature apices and of similar lengths were selected. Teeth having canals with apical diameters larger than size 15 were discarded. The teeth were randomly divided into four experimental groups (n = 15 teeth per group) according to the file used and irrigation systems: (i) OS with PIPS with a 2940 nm Er:YAG laser (0.3 W, 15 Hz, and 20 mJ), (ii) OS with conventional needle irrigation (CNI) with a 27-G needle, (iii) PTN with PIPS and (iv) PTN with CNI. The PIPS and CNI was applied during each file change for 20 s. Total irrigation and activation time was 1 min, and a total volume of 7.5 mL of bidistilled water was used as the irrigant. The apically extruded debris was collected into pre-weighed Eppendorf tubes. The tubes were then stored in an incubator at 70 °C for 5 days. The weight of dry extruded debris was assessed by subtracting the initial weight of the tube from the final weight. The results were analysed statistically using one-way analysis of variance and Tukey's post hoc tests. Bonferroni correction was used to compare the groups. RESULTS The PIPS irrigation technique was associated with significantly more debris extrusion than the CNI system (P < 0.05). The single-file (One Shape-OS) rotary system was associated with more debris than the multiple-file (ProTaper Next-PTN) rotary systems when the same irrigation system was used (P > 0.05). The total amount of debris extruded apically by PIPS activation was significantly greater than that by CNI (P < 0.05). CONCLUSIONS All file and irrigation systems extruded debris apically. PIPS activation was associated with significantly more extrusion debris in curved canals compared with no activation.

Abstract
CONTEXT Introduction of trastuzumab, a recombinant monoclonal antibody against the extracellular domain of HER-2, is a cornerstone in the treatment of HER-2+ breast carcinoma. However, many cancers that have an initial response to trastuzumab will progress some time later. After progression on trastuzumab-based first-line treatment, there are several options. Although TDM-1 (Trastuzumab emtansine) has prolonged progression-free survival (PFS) and overall survival in patients previously treated with trastuzumab and taxane, it is still not available in Turkey. Patients may be switched to lapatinib (an oral tyrosine kinase inhibitor targeting both HER-1 and HER-2), or they may re-challenge with trastuzumab. There is no clear definition of the patients who should be switched to lapatinib. AIM In this study, we investigated the factors predicting the efficacy of lapatinib. SUBJECTS AND METHODS Totally, 94 patients treated with lapatinib for metastatic breast carcinoma was included in our study. Retrospective data including pathology, treatments and treatment results, metastatic sites, and laboratory tests were collected. RESULTS Progression-free survival was 9.1 months. Histologic subtypes other than invasive ductal carcinoma and liver metastasis were inversely related with PFS. Overall survival was 22.1 months, and patients with histologic subtypes other than invasive ductal carcinoma and who progress with brain metastasis had a worse prognosis. CONCLUSION Clinicians should give attention to histologic subtype and metastatic sites when choosing patients for lapatinib treatment.

Abstract
BACKGROUND First- and second-line chemotherapies have been demonstrated to be effective in treatment of patients with inoperable, advanced non-small cell lung cancer (NSCLC), although the role of third-line chemotherapy remains unclear. The present investigation assessed treatment outcomes in patients with advanced NSCLC who received third-line and higher chemotherapy. PATIENTS AND METHODS This retrospective study included consecutive patients with advanced NSCLC who received at least three lines of systemic chemotherapy. RESULTS A total of 72 patients who had received third-line or higher chemotherapy were included in the analysis. The median age of patients was 49 years (range 41-76), and there were 13 (18.1%) women and 59 (81.9%) men. Estimated median survival was 26 months. Moreover, overall survival was significantly longer in patients for whom disease control was achieved after second-line chemotherapy compared to those with disease progression (34 vs. 17 months, respectively). Survival after third-line treatment was significantly longer in the group with Eastern Cooperative Oncology Group (ECOG) performance status 0-1 at the beginning of third-line therapy compared to patients with a status of 2-3. CONCLUSIONS In patients with advanced stage NSCLC, administration of third-line and higher systemic chemotherapy may be associated with increase in overall survival. Furthermore, greater increases in overall survival were also observed in patients for whom disease control was achieved after second-line therapy and in those with ECOG performance status of 0-1 before third-line treatment.

Abstract
OBJECTIVE We present our data comparing retrospectively the efficacy of abiraterone and cabazitaxel in patients who progress after docetaxel treatment. PATIENTS AND METHODS The study included 56 patients diagnosed with hormone-refractory metastatic prostate cancer who were previously treated with abiraterone therapy at four oncology centers in Turkey. RESULTS With abiraterone, the patients had a median progression-free survival (PFS) of 5.9 months (95% confidence interval (CI) for hazard ratio (HR) (4.4-7.4)) and an overall survival of 13.4 months (95% CI for HR (5.5-21.3)). When we compared the disease-free survival (DFS) of reference patients treated with cabazitaxel as a second-line treatment with those receiving second-line abiraterone therapy, there was no significant difference. (PFS = 5.9 months with cabazitaxel vs. 6.7 months with abiraterone, P = 0.213). CONCLUSION This study has shown that in our experience abiraterone acetate is an effective agent in metastatic castration-resistant prostate cancer (mCRPC) regardless of the line of treatment.

Abstract
BACKGROUND Oesophageal squamous cell carcinoma (ESCC) is endemic in the Eastern Anatolian region of Turkey. The present study was performed to identify risk factors for ESCC that specifically reflect the demography and nutritional habits of individuals living in this region. MATERIALS AND METHODS The following parameters were compared in 208 ESCC patients and 200 control individuals in the Eastern Anatolian region: age, sex, place of living, socioeconomic level, education level, smoking, alcohol intake, nutritional habits, and food preservation methods. RESULTS The mean age of ESCC patients was 56.2 years, and 87 (41.8%) were 65 years-old or older. The ratio of women to men in the patient group was 1.39/1. ESCC patients consumed significantly less fruit and yellow or green vegetables and more hot black tea, 'boiled yellow butter', and mouldy cheese than did control individuals. Residence in rural areas, smoking, and cooking food by burning animal manure were also significantly associated with ESCC. CONCLUSIONS The consumption of boiled yellow butter and mouldy cheese, which are specific to the Eastern Anatolian region, and the use of animal manure for food preparation were identified as risk factors in this region. Further studies are required to potentially identify the carcinogenic substances that promote the development of ESCC in this region.

Abstract
Iatrogenic vesicovaginal fistula (VVF) is one of the possible complications after gynecologic operations. However, fistula formation owing to a forgotten foreign body is a rare condition. Infectious complications and subsequent vesicovaginal perforation due to foreign body is difficult to diagnose since it is an unlikely condition. Delays in diagnosis and treatment can lead to serious morbidities and even mortality. This paper aims to discuss a VVF case developed after anterior colporraphy owing to forgotten gauze.

Abstract
Angiomyofibroblastoma is a rare myxoid tumor and is often seen in vulvar and vaginal area. Patients usually present with a mass on the vulva or labium majus at the premenopausal ages. The lesions are usually between 0.5 cm and ten cm. Lesions have quite cellularity with regular borders under the microscope. Lesions contain numerous veins and bulging stromal cells. Treatment of angiomyofibroblastoma is simple surgical resection. Angiomyofibroblastoma should be differentiated from the other vulvar neoplasms, which need radical surgical treatment, especially from the aggressive angiomyxoma. Hereby, the authors aimed to report a premenopausal women presented with vulvar mass and accompanying anemia. She was diagnosed with angiomyofibroblastoma.

Abstract
BACKGROUND Primary ovarian ectopic pregnancy is a rare type of ectopic pregnancy which has an estimated prevalence ranging from 1:7000 to 1:70,000 accounting for almost 3 % of all ectopic cases. Here we report the case of a 25-year-old woman who presented to our clinic with abdominal pain, 6 weeks' delay of menstruation and 3 days of vaginal bleeding, whose transvaginal ultrasonography showed an ectopic gestational sac with yolk sac inside, in her right ovary. This case shows that early diagnosis is very important particularly in places like the Sub-Saharan region of Africa. CASE PRESENTATION A 25-year-old African woman was referred to our clinic with 6 weeks' delay of menstruation, frequent increasing abdominal pain and 3 days of vaginal bleeding. Her general condition was good and her vital signs were normal. She felt tenderness in an abdominal examination and had a small amount of vaginal bleeding. Transvaginal ultrasonography showed an ectopic gestational sac with yolk sac inside, in her right ovary. Our final diagnosis was ectopic ovarian pregnancy and we successfully treated her with methotrexate. After 3 weeks of methotrexate administration her beta human chorionic gonadotropin was negative and a sonographic examination was completely normal. CONCLUSIONS Ectopic ovarian pregnancy is a very important medical situation. It should be diagnosed in its early stages otherwise it could be life-threatening and surgical treatment may be inevitable. Because of the importance of fertility, medical treatment is an acceptable option and can be feasible with early diagnosis.

Abstract
PURPOSE To present information about prognostic factors of gastric cancer patients treated in our Erzurum center including age, gender, tumour location, pathological grade, stage and the effect of treatment on survival. MATERIALS AND METHODS This retrospective study was performed on patients who applied to our clinic and diagnosed as gastric cancer. Age and gender of the patients, primary location, histopathological characteristics, TNM stage of the gastric cancers (GCs), treatment applied, oncological treatment modalities and survival outcomes were studied. A univariate analysis of potential prognostic factors was performed with the log-rank test for categorical factors and parameters with a p value < 0.05 at the univariate step were included in the multivariate regression. RESULTS A total of 228 patients with a confirmed diagnosis of gastric cancer were included in the study with a male/female ratio of 1.47. Median follow-up period was estimated as 22.3 (range, 3 to 96) months. When diagnosis of the patients at admission was analysed, stage III patients were most frequently encountered (n=147; 64.5%). One hundred and twenty-six (55.3%) underwent surgical treatment, while 117 (51.3%) were given adjuvant chemotherapy. Median overall survival time was 18.0 (± 1.19) months. Mean overall survival rates for 1, 2, 3 and 5 years were 68 ± 0.031%, 36 ± 0.033%, 24 ± 0.031% and 15.5 ± 0.036%, respectively. Univariate variables found to be significant for median OS in the multivariate analysis were evaluated with Cox regression analysis. A significant difference was found among TNM stage groups, location of the tumour and postoperative adjuvant treatment receivers (p values were 0.011, 0.025 and 0.001, respectively). CONCLUSIONS This study revealed that it is possible to achieve long-term survival of gastric cancer with early diagnosis. Besides, in locally advanced GC patients, curative resection followed by adjuvant concomitant chemoradiotherapy based on the McDonald regimen was an independent prognostic factor for survival.

Abstract
About 100 million women are estimated to be circumcised globally. Various rates of complications have been encountered, especially after circumcision, such as bleeding, infection, shock, menstrual irregularity, difficulty in urination or common urinary tract infections, inguinal pain, difficulty in sexual intercourse, and genital circumcision scar especially at the vulvar region, and cystic or solid character mass in short and long term. Furthermore, the maternal-fetal morbidity and mortality increase due to bleeding and fistula, which develop after prolonged labor, travail, and difficult labors. Our aim in this paper was to discuss a 42-year-old multiparous female case who had undergone type 2 radical genital mutilation (circumcision) when she was 7 years of age, along with the literature, which has been evaluated for the gradually growing mass at the left inguinal canal region in the last 10 years and diagnosed as epidermoid inclusion cyst developing secondary to postcircumcision surgical ground trauma, since there was no other case found in the literature search that had been circumcised at such an early age and developing after circumcision at such advanced age, and, therefore, this is suggested to be the first case on this subject.

Abstract
BACKGROUND Stage IIIB non-small cell lung cancer (NSCLC) consists of T4N2M0 and TXN3M0 NSCLC. In the present study, we aimed to evaluate the efficacy of different treatment strategies on the survival of patients with radiologically confirmed T4N2M0 NSCLC. METHODS A total of 145 patients were evaluated in three groups according to the treatment protocol: induction chemotherapy followed by chemoradiotherapy (induction group); chemoradiotherapy (CRT group), and chemoradiotherapy followed by consolidation chemotherapy (consolidation group). The groups were compared regarding survival. RESULTS The median progression-free survival (PFS) was 10.9, 10.8 and 17.1 months for the induction, CRT and consolidation groups, respectively (p = 0.021). The median overall survival (OS) was 17.6, 13.8 and 25.2 months for the induction, CRT and consolidation groups, respectively (p = 0.001). CONCLUSIONS The patients with T4N2M0 NSCLC who were treated with chemoradiotherapy followed by consolidation chemotherapy had the best outcome in terms of PFS and OS.

Abstract
Late relapse of testicular cancer, defined as >2 years interval between initial treatment and recurrence, is a rare disease with the incidence rate of 2.6%. Due to its chemoresistant features, treatment options of late relapses are controversial while surgical approach and cisplatin-based chemotherapies can be considered. We report here a patient with nonseminomatous germ cell tumor who experienced relapse 24 years after his first diagnosis. After detecting left supraclavicular lymphadenopathy and absence of any other malignant lesion in positron emission tomography-computerized tomography, patient was treated with three cycles of VeIP regimen (vinblastine/ifosfamide/cisplatin). Second complete response to this treatment was achieved with chemotherapy alone.

Abstract
Breast cancer is the most frequently diagnosed cancer in women worldwide and the second cause of cancer-related mortality. A total of 20-30% of patients with early-stage breast cancer develop recurrence within the first 5 years following diagnosis. Trastuzumab significantly improves overall survival and disease-free survival (DFS) in women with human epidermal growth factor receptor 2 (HER2)-positive early and locally advanced breast cancer. This study aimed to determine the factors that affect DFS following adjuvant transtuzumab therapy. A total of 62 patients treated with trastuzumab for early and locally advanced breast cancer were included in our study. Data, including pathology, treatment and treatment outcome, rate of recurrence and laboratory tests, were retrospectively collected. There was no significant association between DFS and age, menopausal status, disease stage and hormone receptor status. The median follow-up was 48.4 months. The median DFS of patients treated with adjuvant trastuzumab was 64.1 months. In addition, the median DFS was 44.3 vs. 66.8 months in patients with platelet-lymphocyte ratio (PLR) ≤200 vs. >200, respectively (log-rank test; P=0.001), and 70 vs. 45 months in patients with eosinophil count ≤70 vs. >70×103/mm3 (log-rank test; P=0.001). Our data revealed the prognostic relevance of a decrease in the peripheral blood eosinophil count and PLR value following trastuzumab therapy in breast cancer. PLR and eosinophil count measurements are cost-effective, readily available worldwide, non-invasive and safe. Combined with other markers, such as patient age, tumor stage and tumor histology, may be effectively used for patients with breast cancer.

Abstract
BACKGROUND Despite advances in radiotherapy, overall survival of glioblastoma multiforme (GBM) patients is still poor. Moreover dosimetrical analyses with these newer treatment methods are insufficient. The current study is aimed to compare intensity modulated radiation therapy (IMRT) linear accelerator (linac) and helical tomotherapy (HT) treatment plans for patients with prognostic aggressive brain tumors. MATERIAL AND METHODS A total of 20 GBM patient plans were prospectively evaluated in both linac and HT planning systems. Plans are compared with respect to homogenity index, conformity index and organs at risk (OAR) sparing effects of the treatments. RESULTS Both treatment plans provided good results that can be applied to GBM patients but it was concluded that if the critical organs with relatively lower dose constraints are closer to the target region, HT for radiotherapeutical application could be preferred. CONCLUSION Tomotherapy plans were superior to linear accelerator plans from the aspect of OAR sparing with slightly broader low dose ranges over the healthy tissues. In case a clinic has both of these IMRT systems, employment of HT is recommended based on the observed results and future re-irradiation strategies must be considered.

Abstract
INTRODUCTION Breast cancer in young women is a relatively rare disease; however it tends to be more aggressive and is the leading cause of cancer death in this population. The aim of this study is to investigate the clinical and biological features of breast cancer arising in young Turkish breast cancer patients. MATERIALS AND METHODS Patients with breast cancer aged 35 or less (≤35 years) were selected for the study. In total 211 cases were included. Pathologic features; histologic subtypes, grade, lymphovascular invasion, axillary involvement, and stage were recorded for each. RESULTS The most common subtype was luminal B (36.5%), followed by luminal A (30.8%), triple negative (23.2%) and HER2+(9.5%) subtypes. Twelve percent of the patients had stage 4, 32.7% had stage 3, 46.4% had stage 2, and 6.2% had stage 1 disease at the time of diagnosis. Mean tumour diameter was 3.87 cm (range 0.3-13 cm). The axillary lymph nodes were positive in 74.4% of the patients, while lympho-vascular invasion was seen in 56.4%. Some 9.5% of patients had grade 1, 51.2% had grade 2, and 31.8% had grade 3 tumors. CONCLUSIONS Young women with breast cancer in Turkey are more likely to present with luminal B subtype. Tumors in young women are more likely to present with advanced disease, to be high grade and and to have more lymphovascular invasion. Further research should focus on whether we need new treatment strategies for young patients with breast carcinoma.

Abstract
BACKGROUND Treatment of anemia is an important issue in the palliative care setting. Blood transfusion is generally used for this purpose in supportive care. However the place of blood transfusion in terminally ill cancer cases is less far established. OBJECTIVE We aimed to outline the use of transfusions and to find the impact of blood transfusion on survival in patients with advanced cancer and very near to death. DESIGN Patients dying in 2010-2011 with advanced cancer were included in the study. We retrospectively collected the data including age, type of cancer, the duration of last hospitalisation, ECOG performance status, Hb levels, transfusion history of erythrocytes and platelets, cause and the amount of transfusion. The anaemic patients who had transfusion at admission were compared with the group who were not transfused. Survival was defined as the time between the admission of last hospitalisation period and death. RESULTS Three hundred and ninety eight people with solid tumours died in 2010-2011 in our clinic. Ninety percent of the patients had anemia at the time of last hospitalisation. One hundred fifty three patients had erythrocyte transfusion at admission during the last hospitalisation period (38.4%). In the anaemic population the duration of last hospitalisation was longer in patients who had erythrocyte transfusion (15 days vs 8 days, p<0.001). CONCLUSIONS Patients who had blood transfusion at the end of life lived significantly longer than the anaemic patients who were not transfused. This study remarks that blood transfusions should not be withheld from terminal cancer patients in palliative care.

Abstract
OBJECTIVE The aim of this study was to determine the pathological complete response rates in a group of locally advanced rectal cancer patients who underwent chemoradiotherapy (CRT) after treatment with induction folinic acid and 5-florouracil (FOLFOX) chemotherapy and the relationship between the complete response and positron emission tomography-computed tomography (PET-CT). MATERIALS AND METHODS The files of 239 patients who were diagnosed with rectal cancer between January 2008 and January 2012 were evaluated retrospectively. Of these, there were 24 locally advanced rectal cancer patients who met the following criteria: They were administered CRT after receiving four courses induction oxaliplatin, FOLFOX and they underwent PET-CT for staging and for the evaluation of their response to FOLFOX treatment. Of these 24 patients, 20 operable patients were included in the study. RESULTS The pathological complete response was obtained in seven patients (35%) who were operated on and then given induction four courses FOLFOX chemotherapy and CRT. We determined that age, gender, clinical stage at diagnosis and PET-CT before and after induction chemotherapy were not predictive of the pathological complete response to tumor fluorodeoxyglucose uptake activity. CONCLUSION The rates of pathological complete response were increased in locally advanced rectal cancer patients who underwent short-term induction chemotherapy. Although the PET-CT has retained its importance in predicting pathological complete response, there is still a need for studies with a larger number of patients and long-term follow-ups.

Abstract
BACKGROUND Correct working length determination is an important step for successful endodontic therapy. OBJECTIVE The objective was to compare in vitro the accuracy of three electronic apex locators (EALs) (DentaPort ZX [Morita Co., Tokyo, Japan], SIROEndo Pocket [Sirona Dental Systems, NY, USA], and Rootor [Meta Biomed, Cheongwon-gun, Korea]) in detecting the major foramen using the clearing technique. MATERIALS AND METHODS Forty-five human extracted single-rooted teeth with mature apices were used for the study and divided into three groups of 15 teeth each. All teeth were embedded in an alginate model, and the electronic measurements were taken following the manufacturers' orientations. Then, the teeth were cleared and photographed under a stereomicroscope with a digital camera. The distance from the file tip to the major foramen was measured using image analysis software program. Statistical analysis was performed using the Kruskal-Wallis, Mann-Whitney U, and Chi-square tests at a significance level of 0.05. RESULTS The mean distances from the file tip to the major foramen were 0.164 ± 0.292, -0.162 ± 0.234, 0.341 ± 0.166 mm in the DentaPort ZX, SIROEndo Pocket, and Rootor groups, respectively. Statistical analysis showed that there was a significant difference between SIROEndo Pocket and Rootor (P < 0.05). However, no significant difference was found between DentaPort ZX and other EALs (P > 0.05). CONCLUSION DentaPort ZX located the major foramen with 100% accuracy within the range of ± 0.5 mm. However, the accuracy of the SIROEndo Pocket and Rootor in locating the major foramen within ± 0.5 mm was 73.3% and 86.7%, respectively. All EALs showed an acceptable determination of the major foramen within the range of ± 0.5 mm.

Abstract
PURPOSE Relatively few studies have focused on T4N2 (stage IIIB) locally advanced non-small cell lung cancer (NSCLC). In this study, we tried to identify prognostic factors for patients with clinical stage T4N2 NSCLC. METHODS We retrospectively identified 223 patients, of which 168 met the inclusion criteria. Patients treated with curative intent using concurrent chemoradiotherapy (CRT) with or without adjuvant chemotherapy, or concurrent CRT after induction chemotherapy, were included in this study. Relevant patient, treatment, and disease factors were evaluated for their prognostic significance in both univariate and multivariate analyses using the Cox proportional hazards model. RESULTS The median progression-free survival (PFS) was 13 months (95% confidence interval [CI], 10.6-15.4). The median overall survival (OS) was 20 months (95% CI, 16.8-23.1), and 71, 40.3 and 28.2% of the patients survived for 1, 2 and 3 years after diagnosis, respectively. Multivariate analysis showed Eastern Cooperative Oncology Group (ECOG) performance status (PS) was independent predictor of PFS (hazard ratio [HR], 0.24; 95% CI, 0.13-0.43; p=0.001), and OS [HR, 0.48; 95% CI, 0.26-0.87; p=0.015). Absence of multifocal T4 tumors was also associated with a significantly longer OS (HR, 046; 95% CI, 0.31-0.7; p=0.001). There was no statistically significant difference in OS and PFS between treatment modalities. CONCLUSION PFS and OS were significantly shorter in patients with poor ECOG PS. OS was also significantly shorter in patients with multifocal T4 tumors. There were no differences between the two therapeutic approaches with respect to outcome.

Synuclein-gamma predicts poor clinical outcome in esophageal cancer patients. Tumour Biol 2014; 35:11871-7. [PMID: 25142230 DOI: 10.1007/s13277-014-2429-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2014] [Accepted: 07/31/2014] [Indexed: 02/05/2023] Open
Abstract
The synuclein gamma (SNCG) protein, a member of neuronal protein family synuclein, has been considered as a promising potential biomarker as an indicator of cancer stage and survival in patients with cancer. The present study was conducted to evaluate the prognostic value of SNCG in patients with esophageal carcinoma (EC). SNCG levels were assessed immunohistochemically in cancer tissues from 73 EC patients. Median age was 57 (range, 29-78) years old. Forty-seven percent of the patients were male. Thirty-seven percent of the patients had upper or middle localized tumor whereas 59 % had epidermoid carcinoma. More than half of the patients (61 %) had undergone operation where 57 % received adjuvant treatment including chemotherapy or chemotherapy plus radiotherapy. Median overall survival was 11.3 ± 1.8 months (95% confidence interval (CI): 7.7-14.9 months). SNCG positivity was significantly associated with the histological type of EC and inoperability (for SNCG positive vs. negative group; epidermoid 80 vs. 53 %; p = 0.05 and inoperable 59 vs.32 %; p = 0.04, respectively). Lymph node metastasis, inoperability and receiving no adjuvant treatment had significantly adverse effect on survival in the univariate analysis (p = 0.01, p < 0.001, and p = 0.001, respectively). SNCG positivity had significantly adverse effect on survival in both univariate and multivariate analysis (p = 0.02 and p = 0.01, respectively). Our results are the first to suggest that SNCG is a new independent predictor for poor prognosis in EC patients in the literature.

Abstract
Background An increasing number of patients receive palliative chemotherapy near the end of life. The aim of this study is to evaluate the aggressiveness of chemotherapy in Turkish individuals near the end of life. Methods Patients diagnosed with solid tumors and died from 2010 to 2011 in the medical oncology department of Akdeniz University were included in the study. Data about the diagnosis, treatment details and imaging procedures were collected. Results Three hundred and seventy-three people with stage IV solid tumors died from 2010 to 2011 in our clinic. Eighty-nine patients (23.9%) patients underwent chemotherapy in the last month of life while 39 patients (10.5%) received chemotherapy in the last 14 days. The probability of undergoing chemotherapy in the last month of life was influenced by: age, ‘newly diagnosed’ patients, and performance status. There was no significant association of chemotherapy in the last month of life with gender and tumor type. Having a PET-CT scan did not alter the chemotherapy decision. Conclusion In conclusion, chemotherapy used in the last month of life in a tertiary care center of Turkey is high. Increasing quality of life should be a priority near the end of life and physicians should consider ceasing chemotherapy and direct the patient to early palliative care.

Abstract
OBJECTIVES The aim of this study was to evaluate the accuracy of four electronic apex locators (EALs) (DentaPort ZX, Raypex 5, Endo Master and VDW Gold) in detecting the major foramen using the clearing technique. MATERIALS AND METHODS Forty-eight extracted single-rooted extracted teeth with mature apices were used for the study and divided into four groups of 12 teeth each. All teeth were embedded in an alginate model. Electronic measurements were taken using a size 15 K-file attached to the holder. Then, the teeth were cleared and photographed under a stereomicroscope with a digital camera. The distance between the tip of the file and the major foramen was measured by using an image analysis software program. Positive and negative values were recorded when the file tip was beyond or short of the major foramen and zero value when the file tip and the major foramen coincided. Statistical analysis was performed using the Kruskal-Wallis and Chi-square tests at a significance level of 0.05. RESULTS Mean distance from the file tip to the major foramen were 0.302 ± 0.202, 0.065 ± 0.293, 0.117 ± 0.475, and 0.258 ± 0.160 mm in the DentaPort ZX, Raype 5, Endo Master, and VDW Gold groups, respectively. There were no statistically significant differences among the devices (P > 0.05) . CONCLUSION Under the experimental conditions, all EALs showed an acceptable determination of the major foramen.

Abstract
BACKGROUND Malignant mesothelioma (MM) is almost always fatal and few treatment options are available. The aim of this study was to evaluate the efficacy of oral cyclophosphamide and etoposide for patients who underwent standard treatment for advanced MM. MATERIALS AND METHODS This study included 22 malignant pleural mesothelioma patients who were treated with oral cyclophosphamide and etoposide (EE). RESULTS The average follow-up period of the patients was 39.1 months. Under the treatment of oral EE, median progression- free survival was 7.7 months [95%CI HR (4.3-11.1)] and median overall survival was 28.1 months [95%CI HR (5.8-50.3)]. The treatment response rates were as follows: 4 patients (27.3%) had a partial response (PR), 12 (54.5%) had stable disease (SD), and progressive disease (PD) was observed in 6 (35.9%). CONCLUSIONS Oral EE can be administered effectively to patients with inoperable malignant mesothelioma who had previously received standard treatments.
