Abstract
Hereditary Breast and Ovarian Cancer (HBOC) syndrome is characterized by an increased risk of developing breast cancer (BC) and ovarian cancer (OC) due to inherited genetic mutations. Understanding the genetic variants associated with HBOC is crucial for identifying individuals at high risk and implementing appropriate preventive measures. The study included 630 Turkish OC patients with confirmed diagnostic criteria of The National Comprehensive Cancer Network (NCCN) concerning HBOC. Genomic DNA was extracted from peripheral blood samples, and targeted Next-generation sequencing (NGS) was performed. Bioinformatics analysis and variant interpretation were conducted to identify pathogenic variants (PVs). Our analysis revealed a spectrum of germline pathogenic variants associated with HBOC in Turkish OC patients. Notably, several pathogenic variants in BRCA1, BRCA2, and other DNA repair genes were identified. Specifically, we observed germline PVs in 130 individuals, accounting for 20.63% of the total cohort. 76 distinct PVs in genes, BRCA1 (40 PVs), BRCA2 (29 PVs), ATM (1 PV), CHEK2 (2 PVs), ERCC2 (1 PV), MUTYH (1 PV), RAD51C (1 PV), and TP53 (1PV) and also, two different PVs (i.e., c.135-2 A>G p.? in BRCA1 and c.6466_6469delTCTC in BRCA2) were detected in a 34-year-old OC patient. In conclusion, our study contributes to a better understanding of the genetic variants underlying HBOC in Turkish OC patients. These findings provide valuable insights into the genetic architecture of HBOC in the Turkish population and shed light on the potential contribution of specific germline PVs to the increased risk of OC.

Abstract
Ovarian cancer (OC) ranks as the eighth most prevalent malignancy among women globally. The short non-coding RNA molecules, microRNAs (miRNAs) target multiple mRNAs and regulate the gene expression. Here in this study, we aimed to validate miR-3135b and miR-1273g-3p as novel biomarkers for prognostic and diagnostic factor OC. After RNA isolation, we analyzed the miR-3135b and miR-1273g-3p expression in peripheral blood samples derived from 150 OC patients. Subsequently, we compared their expression levels with 100 healthy controls. The differences of miR-3135b and miR-1273g-3p expression were detected using the Quantitative Real Time-PCR (qRT-PCR) technique following miRNA-specific cDNA synthesis pursing miRNA separation. The miR-3135b and miR-1273g-3p were higher in OC patients who tested positive for BRCA1/2 compared to BRCA-negative patients, and healthy cases. The level of miR-3135b demonstrated a roughly 4.82-fold increase in OC patients in comparison to the healthy cases, while miR-1273g-3p expression exhibited a roughly 6.77-fold increase. The receiver operating characteristic (ROC) analysis has demonstrated the potential of miR-3135b and miR-1273g-3p as markers for distinguishing between OC patients and healthy controls. The higher expressions of miR-3135b and miR-1273g-3p could be associated with OC development. Moreover, miR-3135b may have a diagnostic potential and miR-1273g-3p may have both diagnostic and prognostic potential in OC cell differentiation. The string analysis has revealed an association between miR-1273g-3p and the MDM2 gene, suggesting a potential link to tumor formation through the proteasomal degradation of the TP53 tumor suppressor gene. Additionally, the analysis indicates an association of miR-1273g-3p with CHEK1, a gene involved in checkpoint-mediated cell cycle arrest. String analysis also indicates that miR-3135b is associated with the MAPK1 gene, causing activation of the oncogenesis cascade. In conclusion, miR-1273g-3p, and miR-3135b exhibit significant potential as diagnostic markers. However, further research is needed to comprehensively investigate these miRNAs diagnostic and predictive characteristics in a larger cohort.

Abstract
Mucopolysaccharidosis (MPS) IVA is a lysosomal storage disorder caused by mutations in the GALNS gene that leads to the lysosomal accumulation of keratan sulfate (KS) and chondroitin 6-sulfate, causing skeletal dysplasia and cardiopulmonary complications. Current enzyme replacement therapy does not impact the bone manifestation of the disease, supporting that new therapeutic alternatives are required. We previously demonstrated the suitability of the CRISPR-nCas9 system to rescue the phenotype of human MPS IVA fibroblasts using iron oxide nanoparticles (IONPs) as non-viral vectors. Here, we have extended this strategy to an MPS IVA mouse model by inserting the human GALNS cDNA into the ROSA26 locus. The results showed increased GALNS activity, mono-KS reduction, partial recovery of the bone pathology, and non-IONPs-related toxicity or antibody-mediated immune response activation. This study provides, for the first time, in vivo evidence of the potential of a CRISPR-nCas9-based gene therapy strategy for treating MPS IVA using non-viral vectors as carriers.

Abstract
Lysosomal storage diseases (LSDs) are caused by monogenic mutations in genes encoding for proteins related to the lysosomal function. Lysosome plays critical roles in molecule degradation and cell signaling through interplay with many other cell organelles, such as mitochondria, endoplasmic reticulum, and peroxisomes. Even though several strategies (i.e., protein replacement and gene therapy) have been attempted for LSDs with promising results, there are still some challenges when hard-to-treat tissues such as bone (i.e., cartilages, ligaments, meniscus, etc.), the central nervous system (mostly neurons), and the eye (i.e., cornea, retina) are affected. Consistently, searching for novel strategies to reach those tissues remains a priority. Molecular Trojan Horses have been well-recognized as a potential alternative in several pathological scenarios for drug delivery, including LSDs. Even though molecular Trojan Horses refer to genetically engineered proteins to overcome the blood-brain barrier, such strategy can be extended to strategies able to transport and deliver drugs to specific tissues or cells using cell-penetrating peptides, monoclonal antibodies, vesicles, extracellular vesicles, and patient-derived cells. Only some of those platforms have been attempted in LSDs. In this paper, we review the most recent efforts to develop molecular Trojan Horses and discuss how this strategy could be implemented to enhance the current efficacy of strategies such as protein replacement and gene therapy in the context of LSDs.

Abstract
The aim of the study was to investigate the frequency and types of mutations on the retinoblastoma gene (RB1 gene) in Turkish population. RB1 gene mutation analysis was performed in a total of 219 individuals (122 probands with retinoblastoma, 14 family members with retinoblastoma and 83 clinically healthy family members). All 27 exons and close intronic regions of the RB1 gene were sequenced for small deletions and insertions using both the Sanger sequencing or NGS methods, and the large deletions and duplications were investigated using the MLPA analysis and CNV algorithm. The bilateral/trilateral retinoblastoma rate was 66% in the study population. The general frequency of RB1 gene mutation in the germline of the patients with retinoblastoma was 41.9%. Approximately 51.5% of the patients were diagnosed earlier than 12 months old, and de novo mutation was found in 32.4% of the patients. Germline small genetic rearrangement mutations were detected in 78.9% of patients and LGRs were detected in 21.1% of patients. An association was detected between the eye color of the RB patients and RB1 mutations. 8 of the mutations detected in the RB1 gene were novel in the study.

Abstract
BACKGROUND One of the main features of cancer, especially lung cancer (LC), is abnormal cell division. Abnormal expression of kinesin family member C1 (KIFC1/HSET), which is involved in mitotic cell division and ensures equatorial alignment of chromosomes during division, is observed in both premalignant and malignant lesions. There are no studies in the literature addressing the role of KIFC1 in the diagnosis and follow-up of LC. In this study, we investigated the epigenetic role of KIFC1 in the diagnosis, stage, and prognosis of various histological subtypes diagnosed with LC. MATERIAL AND METHODS The expression and methylation status of the KIFC1 gene were examined after DNA/RNA isolation in tumor, conjugate normal tissue, and blood samples from 39 patients diagnosed with LC and in blood samples from 39 healthy controls. Changes in KIFC1 gene expression were examined by the Quantitative Real Time-PCR (qRT-PCR) method after cDNA synthesis following RNA isolation. The Methylation-Specific PCR (MSP) method was used to determine the methylation status of the KIFC1 gene. In this study, the expression/methylation profiles of the KIFC1 gene and the clinical and pathological characteristics of the patients were analyzed by statistical methods. RESULT Hypomethylation was detected in 95.8% of the 62.1% of patients' tissues with increased KIFC1 gene expression. The expression level of the KIFC1 gene was found to be increased 3.2-fold in the tumor tissues of the patients compared with the conjugated normal tissues and 2.4-fold in the serum of the patients compared with the healthy serum. Statistical comparison of patients' clinical parameters and methylation and expression results revealed statistical significance between KIFC1 expression and metastasis, tumor stage and tumor grade. CONCLUSION In conclusion, the increase in the expression level of the KIFC1 gene is higher in patients diagnosed with LC than in the healthy population, and therefore, the increase in the expression level of the KIFC1 gene due to hypomethylation can be used as a screening biomarker in LC. It can also be considered that the methylation profile of the KIFC1 gene may be a potential biomarker for determining the subtype of squamous cell carcinoma in LC. The results of the study need to be analyzed and continued with a larger number of patients.

Abstract
Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is caused by a deficiency of the N-acetylgalactosamine-6-sulfate-sulfatase (GALNS) enzyme, leading to the accumulation of glycosaminoglycans (GAG), keratan sulfate (KS) and chondroitin-6-sulfate (C6S), mainly in cartilage and bone. This lysosomal storage disorder (LSD) is characterized by severe systemic skeletal dysplasia. To this date, none of the treatment options for the MPS IVA patients correct bone pathology. Enzyme replacement therapy with elosulfase alpha provides a limited impact on bone growth and skeletal lesions in MPS IVA patients. To improve bone pathology, we propose a novel gene therapy with a small peptide as a growth-promoting agent for MPS IVA. A small molecule in this peptide family has been found to exert biological actions over the cardiovascular system. This work shows that an AAV vector expressing a C-type natriuretic (CNP) peptide induces bone growth in the MPS IVA mouse model. Histopathological analysis showed the induction of chondrocyte proliferation. CNP peptide also changed the pattern of GAG levels in bone and liver. These results suggest the potential for CNP peptide to be used as a treatment in MPS IVA patients.

Abstract
INTRODUCTION To compare performance of indivisual categories between the Johns Hopkins template and the Paris system for reporting urinary cytology. METHODS Medical records of patients with bladder biopsy and relevant cytology slides were obtained from archived material. Slides were reclassified according to Johns Hopkins Template and the Paris. Results were compared to histologic diagnoses. RESULTS BD SurePath preparations from 205 cases with biopsy follow up (118 benign, 5 dysplasia, 23 low-and 59 malignant urothelial carcinoma (UC)) were reviewed. There were 2 inadequate specimens in each system. According to the Johns Hopkins Template, there were 96 (46.8%) no urothelial atypia or malignancy, 37 (18%) atypical urothelial cells of uncertain significance (AUC-US), 21 (10.2%) atypical urothelial cells, cannot exclude HGUC (AUC-H), 38 (18.5%) high grade urothelial carcinoma (HGUC) , and 11 (5.4%) low grade urothelial carcinoma (LGUC). The Paris System categorized 111 (54.1%) negative for high grade urothelial carcinoma, 29 (14.1%) atypical urothelial cells (AUC), 25 (12.2%) suspicious for HGUC (SHGUC), 36 (17.6%) HGUC and 2 (1%) LGUC. The Johns Hopkins Template had a sensitivity of 95.6%, specificity of 73.6%, Positive Predictive Value of 61.5%, Negative Predictive Value of 96.3, with an overall diagnostic accuracy of 79.8%. The Paris System had a sensitivity of 93.6%, specificity of 77.9%, Positive Predictive Value of 65.6%, Negative Predictive Value of 96.5, with an overall diagnostic accuracy of 82.8%. The Risk of Malignancy (ROM) for atypical category (AUC-US/AUC) in the Johns Hopkins Template was 43.2%, while it has been 24.1% for the Paris System. The ROM for suspicious category was 47.6% and 68.0% respectively. There was a statistically significant differences between negative and atypical, suspicious, and HGUC categories in each system (p<0.0001). CONCLUSIONS Discrete negative or benign urine cytology had the same sensitivity and specificity between two systems. Although atypical category associated with a higher ROM with the Hopkins template, the ROM for the suspicious category yielded better result with the Paris system.

Abstract
The most prevalent malignant bone tumor, osteosarcoma, affects the growth plates of long bones in adolescents and young adults. Standard chemotherapeutic methods showed poor response rates in patients with recurrent and metastatic phases. Therefore, it is critical to develop novel and efficient targeted therapies to address relapse cases. In this regard, RNA interference technologies are encouraging options in cancer treatment, in which small interfering RNAs regulate the gene expression following RNA interference pathways. The determination of target tissue is as important as the selection of tissue-specific promoters. Moreover, small interfering RNAs should be delivered effectively into the cytoplasm. Lentiviral vectors could encapsulate and deliver the desired gene into the cell and integrate it into the genome, providing long-term regulation of targeted genes. Silencing overexpressed genes promote the tumor cells to lose invasiveness, prevents their proliferation, and triggers their apoptosis. The uniqueness of cancer cells among patients requires novel therapeutic methods that treat patients based on their unique mutations. Several studies showed the effectiveness of different approaches such as microRNA, drug- or chemotherapy-related methods in treating the disease; however, identifying various targets was challenging to understanding disease progression. In this regard, the patient-specific abnormal gene might be targeted using genomics and molecular advancements such as RNA interference approaches. Here, we review potential therapeutic targets for the RNA interference approach, which is applicable as a therapeutic option for osteosarcoma patients, and we point out how the small interfering RNA method becomes a promising approach for the unmet challenge.

Abstract
Background We aimed to evaluate the prevalence of predisposing factors and oral manifestations in SARS-CoV-2 infection. Material and Methods 204 SARS-CoV-2 positive patients were included in the study. Questions regarding the systemic, periodontal health, oral hygiene habits, common symptoms and, oral manifestations of COVID-19 such as oral lesions, and dry mouth were included in the survey. The Visual Analogue Scale (VAS) was used. Results 47.5% of individuals had various systemic diseases. Dry mouth (44.2%) and oral lesions (22.4%) were the most common oral manifestations in COVID-19 patients. Also, dry mouth had the highest VAS score. The most common oral lesion locations were buccal mucosa (15.2%) and tongue (10.8%). The majority of participants (142 patients) were affected by taste disorders. Patients who received periodontal treatment before SARS-CoV-2 infection reported fewer oral complaint and manifestations than those who did not receive periodontal therapy (p=0.032). There was no statistically significant difference between males and females on the presence of any oral manifestations, and taste disorders. Conclusions Our results showed that SARS-CoV-2 could cause oral manifestations. However various predisposing factors may be part of the etiology and promote oral findings. Key words:SARS-CoV-2, COVID-19, xrestomia, dysgeusia, oral manifestation.

Abstract
e22007 Background: Retinoblastoma (RB) is the most common intraocular malignancy in children, caused by mutations in the tumor suppressor RB1 gene. Patients with bilateral/trilateral/familial RB are considered to have hereditary RB (1 germline, 1 somatic mutation); although most unilateral RB are nonhereditary (2 somatic mutations), some have germline RB1 mutation. Identification of RB1 mutations and genetic counseling is essential to assess the risk of developing RB in the patients´ relatives and to prevent the disease. The aim of this study is to assess the frequency/type of RB1 gene mutations in a large cohort of Turkish RB cases. Methods: RB1 gene mutation screening was performed in peripheral blood samples of 219 individuals (122 children with RB/14 family members with RB/83 healthy family members of 47 probands with RB1 mutations) followed in the Istanbul University, Oncology Institute. All 27 exons and close intronic regions of the RB1 gene were sequenced for small deletions and insertions using the Sanger sequencing (2013-2018) or Next Generation Sequencing (2019-2021); large deletions and duplications were investigated both by Multiplex Ligation Probe Amplification (MLPA) and copy number variation (CNV). Correlation with demographic and clinical data were evaluated. Results: After RB1 mutation screening, mutations were detected in 57 (41.9%) of 136 patients. RB1 mutations was observed in 23/84 (27.4%) patients with unilateral RB, in 30/47 (63.8%) bilateral RB, in 3/3 trilateral RB, and1/2 unilateral retinoma. Of these mutations, 45 (78.9%) were small genetic rearrangements and 12 (21.1%) large genetic rearrangements. Frameshift mutations were found in 11, nonsense in 18, splice error in 11, and missense mutation in 1, synonymous substitution in 2, upstream substitution in 2 patients. Ten novel mutations were found. Three of 83 healthy family members also had germline RB1 mutation. The disease was hereditary in 13 (22.8%); and de novo (77.2 %) in 44 of the 57 patients with mutations. Three siblings were found to have RB1 mutation, while their parents did not. Patients diagnosed as infants (RB1 mutation found in 63.2% of 70 infants vs in 36.8% of older ones, p:0.021); those with bilateral/trilateral RB (66 vs 27.4%, p:0.0001); those with light (green-blue) iris color vs dark color (71.4% vs 36.5%. p:0.003) had higher frequency of RB1 gene mutation. There was no significant correlation regarding gender or ICRB stage and RB1 mutation frequency. Conclusions: RB1 gene mutation was found in 41.9% of Turkish children with RB, in 63.8% of bilateral and 27.4% of unilateral RB. 10 novel mutations of the RB1 gene were found according to the Leiden Open Variation Database and the Human Gene Mutation Database.The mutation frequency was significantly higher in patients with bilateral/trilateral RB, in infants, in those with light iris color. In bilateral RB with no RB1 mutation, other genes/RB1 gene methylation and expression status may play a role in the pathogenesis.

Abstract
MicroRNAs (miRNAs) are the non-coding RNAs that can both attach to the untranslated and coding sections of target mRNAs, triggering destruction or post-transcriptional alteration. miRNAs regulate various cellular processes such as immune function, apoptosis, and tumorigenesis. About 35,000 miRNAs have been discovered in the human genome. The increasing evidence suggests that the dysregulation of human miRNAs may have a role in the etiology of some disorders including cancer. Only a small sub-set of human miRNAs has functionally been validated in the pathogenesis of oncogenic viruses such as Kaposi’s sarcoma-associated herpesvirus (KSHV). KSHV is the cause of various human malignancies including primary effusion lymphoma (PEL) and Kaposi’s sarcoma (KS), which are mainly seen in AIDS patients or other immunocompromised people. We aimed to identify the miRNAs in Kaposi’s sarcoma cases, with the comparison of KSHV seropositive and seronegative tumors with the controls and in each other in Turkish Kaposi’s sarcoma patients. We performed the miRNA-sequencing at genome level in the peripheral blood mononuclear cells of 16 Kaposi’s sarcoma patients, and in 8 healthy controls matched for age, gender, and ethnicity. A total of 642 miRNA molecules with different expression profiles were identified between the patients and the healthy controls. Currently, out of 642 miRNAs, 7 miRNAs (miR-92b-3p, miR-490-3p, miR-615-3p, miR-629-5p, miR-1908, miR-3180, miR-4433b-3p) which have not been described in the literature in the context of Kaposi’s sarcoma were addressed in the study for the first time and 9 novel miRNAs, not found previously in the database, have been detected in Kaposi’s sarcoma using the miRNA-sequencing technique. This study demonstrates the identification of differently expressed miRNAs which might be the new therapeutic targets for Kaposi’s sarcoma, that has limited treatment options and can be used in the etiology, diagnosis, and prognosis of this cancer.

Abstract
BACKGROUND It is challenging to determine whether Bacillus species other than Bacillus anthracis cause infections. Pseudo and true outbreaks of Bacillus spp. have been noted. Here, we present a molecular analysis of a Bacillus spp. pseudo-outbreak caused by contaminated culture tubes containing Stuart medium. METHODS Between January and March 2015, a high percentage of Bacillus spp. was isolated from the wound samples of inpatients at the Karabuk University Hospital, and an outbreak was suspected. Environmental and staff nasal samples were cultured aerobically, and Bacillus spp. were isolated from some of them. However, the isolation of Bacillus spp. in throat cultures of outpatients suggested contamination caused by culture tubes containing Stuart medium. We examined two lots of culture tubes used in the hospital. Although the culture tubes' expiry date and storage conditions were suitable, Bacillus spp. grew in one of these lots. A total of 47 Bacillus spp. isolated during this period were identified, and the clonal relationship among the isolates was investigated by arbitrarily primed polymerase chain reaction. RESULTS Twenty-seven strains were identified as Bacillus megaterium and 20 as Bacillus firmus. Of the four strains isolated from the Stuart medium, two were identified as B. firmus and the other two were B. megaterium. Two B. firmus strains isolated from the Stuart medium and two B. firmus strains obtained from the coronary intensive care environmental samples were matched and clustered within the same genotype. We recalled all culture tubes containing Stuart medium. After another brand's culture tubes were distributed, no growth was observed. It was then understood that the pseudo-outbreak source was contaminated culture tubes containing Stuart medium. CONCLUSIONS Microbiological controls of medical materials and equipment should be regularly checked to prevent outbreaks (true or pseudo).

Abstract
The most common gynecologic cancers detected in women in Turkey are uterine cancer, ovarian cancer, and cervical cancer. These data reported that a mean of 3800 individuals were diagnosed with uterine cancer, 2790 were diagnosed with ovarian cancer, and 1950 were diagnosed with cervical cancer, and 400 individuals were diagnosed with other gynecologic cancers each year in Turkey. A mean of 14.270 individuals were detected to have been diagnosed with gynecologic cancers each year in the United States of America (USA). Ovarian cancer treatment is generally composed of chemotherapy, and surgery. In general, chemotherapy is administered after surgery. The identification of the molecular pathogenesis of ovarian cancer, and discovery of new moleculer biomarkers which facilitate the ovarian cancer treatment are required for an effective ovarian cancer treatment in clinics. miRNAs are reported to be the possible biologic indicators for various cancer types. We aimed to investigate 2 miRNAs which were suggested to have effect in ovarian cancer in our (previous) monozygotic twin study from miR-1260 microRNA family whose association with ovarian cancer yet has not been reported in the literature. We investigated the expression levels of miR-1260a, and miR-1260b miRNAs, in the peripheral blood lymphocytes of 150 familial and sporadic ovarian cancer patients, and of 100 healthy individuals of the control group who were matched for age, sex, and ethnicity with the patient group, and investigated their possible property of being a biologic indicator for ovarian cancer. The expression results of ovarian cancer patients were evaluated by comparison of the results of the control group in the study. The expression levels of miR-1260a, and miR-1260b in ovarian cancer patients were found highly increased compared with the levels in the control group. miR-1260a expression level in ovarian cancer patients was detected to have increased approximately 17 fold compared with the control group, and miR-1260b expression level in ovarian cancer patients was detected to have increased approximately 33 fold compared with the levels in the control group. The String Analyses showed that the miR-1260a was associated with the ribosomal protein family which was known to be effective in the translation stage of cell and that miR-1260b was associated with CHEK2 protein which was a member of the serine/threonine-protein kinase family. It should be investigated for larger cohorts in benign ovarian diseases and in different stages of patients receiving ovarian cancer treatment whether these two molecules are a noninvasive biomarker and therapeutic target to be used especially in the early diagnosis and prognosis of ovarian cancer in future.

Abstract
Background Mucopolysaccharidosis IVA (MPS IVA, also called Morquio A syndrome) is caused by a deficiency of N‐acetylglucosamine‐6‐sulfate sulfatase (GALNS) and results in skeletal dysplasia symptoms such as short stature and abnormal gait. Treatments include enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT), but the effects are limited depending on the age of initiation and clinical phenotype. Thus, this study aims to assess the effects of treatments on MPS IVA patients compared to untreated MPS IVA patients and an age‐matched control group. Methods We used activity of daily living (ADL) survey with 4 sections: “movement,” “movement with cognition,” “cognition,” and “other MPS symptoms.” Lower scores indicate more assistance required. This study included 161 patients, 270 total surveys, and 70 patients with longitudinal data. Results We describe 134 severe patients and 25 attenuated patients. ERT and HSCT treatment improved only the “other MPS symptoms” section in severe patients. There were no differences between ERT and HSCT severe patient scores. A 19‐year‐old male patient, who had robust physical training, provided a significant increase in “movement” without treatment, suggesting the importance of exercise. Conclusion Overall, this ADL questionnaire has demonstrated validation and reliability in assessing the MPS IVA patients and therapeutic efficacy.

Abstract
Glycosaminoglycans (GAGs) are present in proteoglycans, which play critical physiological roles in various tissues. They are known to be elevated in mucopolysaccharidoses (MPS), a group of rare inherited metabolic diseases in which the lysosomal enzyme required to break down one or more GAG is deficient. In a previous study, we found elevation of GAGs in a subset of patients without MPS. In the current study, we aim to investigate serum GAG levels in patients with conditions beyond MPS. In our investigated samples, the largest group of patients had a clinical diagnosis of viral or non-viral encephalopathy. Clinical diagnoses and conditions also included epilepsy, fatty acid metabolism disorders, respiratory and renal disorders, liver disorders, hypoglycemia, developmental disorders, hyperCKemia, myopathy, acidosis, and vomiting disorders. While there was no conclusive evidence across all ages for any disease, serum GAG levels were elevated in patients with encephalopathy and some patients with other conditions. These preliminary findings suggest that serum GAGs are potential biomarkers in MPS and other disorders. In conclusion, we propose that GAGs elevated in blood can be used as biomarkers in the diagnosis and prognosis of various diseases in childhood; however, further designed experiments with larger sample sizes are required.

Abstract
Objectives We aimed to evaluate the efficacy of continuous local anesthetic infusion to the incision site with the On-Q elastomeric pump system in postoperative acute pain control after thoracotomy. Methods A retrospective comparative analysis of of sixty patients who underwent thoracotomy for lung cancer by the same surgical team was performed between January 2016 and December 2017. The patients were divided into two groups according to postoperative pain management, those who were traditionally received tramadolol (15 mg/h) by intravenous continuous infusion (Group IVT, n = 30) and those who were administered continuous local anesthetic (0.5% bupivacaine, 4 ml/h) infusion to the incision site through an elastomeric pump in addition to the traditional treatment (Group LA, n = 30). The primary outcomes were postoperative acute pain scores on the numeric rating scale and postoperative rescue opioid consumption for 72 hours following surgery reported as pethidine equivalents. The secondary outcomes were frequency of analgesia related adverse events/complications, ICU and hospital stay, drug and total hospital cost. Results The mean pain scores at 2, 12, 24, 48 and 72th hours at rest and during coughing were found to be significantly lower in group LA (p < 0.05). Rescue opioid consumption on postoperative 0, 1, 2 and 3rd days and in total was found to be significantly lower in Group LA (p < 0.05). In Group LA, postoperative length of hospital stay was significantly shorter (5.8 ± 2.1 days vs. 8.0 ± 3.1 days; p = 0.034), drug costs (95.24 vs. 160.08 Euro; p = 0.023) and total hospital costs were lower (434.26 vs. 685.75 Euro; p = 0.014) than Group IVT. Conclusions We believe that continuous local anesthetic infusion to the incision site in addition to systemic analgesic treatment for multimodal acute pain management after thoracotomy is an effective and safe method.

Abstract
BACKGROUND In this study, we aimed to evaluate the salivary β-galactosidase and Halimeter values (HMV), organoleptic scores (OLS) and Winkel tongue coating index (WTCI) in periodontal health and periodontitis (P), and also their changes after phase I periodontal therapy and tongue cleaning. METHODS The participants were separated as follows: 25 P with halitosis (Group 1), 25 P without halitosis (Group 2) and 25 healthy controls (Group 3). Periodontal recordings, HMV, OLS and WTCI scores were recorded, and whole saliva β-galactosidase levels were measured colorimetrically in the samples at baseline and 1 month after the therapy. RESULTS The baseline values of HMV, OLS, WTCI and salivary β-galactosidase levels were significantly higher in Group 1 than in Group 2 (P < 0.05). There was a statistically significant decrease in periodontal recordings, HMV, OLS, WTCI and salivary β-galactosidase levels in all P patients by the therapy (P < 0.05). However, major reductions in halitosis measurements and saliva enzyme levels were observed in Group 1 after the treatment. CONCLUSION Our results showed that salivary β-galactosidase was associated with halitosis parameters and phase I periodontal therapy played an important role to reduce this enzyme level and halitosis parameters in P.

Abstract
The aim of this experimental study was to evaluate the reliability of two-plate fixations applied to the anterior region of the maxilla after Le Fort I osteotomy in terms of stability. Twenty polyurethane-based skull models were used to evaluate two fixation techniques. Two groups consisting of four and two L-shaped titanium miniplates were tested. Each group was tested with the application of vertical forces in the anteroposterior direction using a servohydraulic testing unit. The displacement values in each group at each stage (from 10 N - 120 N) were compared using the Mann-Whitney U test. The displacement values for the two groups were not statistically significant up to 20 N, but differed significantly between 20 N and 120 N (p < 0.05). The results showed that the biomechanical behaviour of fixation with four miniplates was better than that of two after a load of 20 N. It can be concluded that when the amount of maxillary advancement is increased to 10 mm or more, fixation with only two plates does not provide sufficient stability experimentally.

Abstract
Ovarian cancer is a disease that is generally diagnosed at an advanced stage, and has poor survival. Monozygotic (MZ) twins are considered to be good research models for investigating the epigenetic changes associated with diseases. In the present study, the involvement of epigenetic mechanisms in ovarian cancer etiology were evaluated using the MZ twin model. Whole-genome methylation patterns were investigated in a BRCA1 gene mutation-carrying family comprising MZ twins, only one of whom had ovarian cancer, and other healthy siblings. Whole-genome methylation patterns were assessed in peripheral blood DNA using Infinium MethylationEPIC BeadChips on an Illumina iScan device. The hypermethylated and hypomethylated genes were detected between cases and controls in four different comparison groups in order to evaluate the differences in methylation levels according to cancer diagnosis and BRCA mutation status. The obtained results showed that the differential methylations in 12 different genes, namely PR/SET domain 6, cytochrome B5 reductase 4, ZNF714, OR52M1, SEMA4D, CHD1L, CAPZB, clustered mitochondria homolog, RB-binding protein 7, chromatin repair factor, ankyrin repeat domain 23, RIB43A domain with coiled-coils 1 and C6orf227, were associated with ovarian cancer. Biological functional analysis of the genes detected in the study using the PANTHER classification system revealed that they have roles in biological processes including ‘biologic adhesion’, ‘regulation’, ‘cellular components organization’, ‘biogenesis’, ‘immune system functioning’, ‘metabolic functioning’ and ‘localization’. Overall, the present study suggested that epigenetic differences, such as methylation status, could be used as a non-invasive biological markers for the early diagnosis and follow-up of ovarian cancer.

Abstract
BACKGROUND Ovarian cancer is the second most common gynecologic cancer with high mortality rate and generally diagnosed in advanced stages. The 5-year disease-free survival is below 40%. MicroRNAs, subset of the non-coding RNA molecules, regulate the translation in post transcriptional level by binding to specific mRNAs to promote or degrade the target oncogenes or tumor suppressor genes. Abnormal expression of miRNAs were found in numerous human cancer, including ovarian cancer. Investigating the miRNAs derived from the peripheral blood samples can be used as a marker in the diagnose, treatment and prognosis of ovarian cancer. We aimed to find biological markers for early diagnosis of ovarian cancer by investigating BRCA1 gene mutation carrier monozygotic discordant twins and their high risk healthy family individual's miRNAs. METHODS The study was conducted on monozygotic twins discordant for ovarian cancer, and the liquid biopsy exploration of miRNAs was performed on mononuclear cells that were isolated from the peripheral blood samples. The miRNA expression profile changes in the study were found by using microarray analysis. miRNA isolation procedure performed from the lymphocyte in accordance with the kit protocol. The presence and quality of the isolated miRNAs screened by electrophoresis. Raw data logarithmic analysis was studied by identifying the threshold, normalization, correlation, mean and median values. Target proteins were detected for each miRNA by using different algorithms. RESULTS After the comparison of monozygotic discordant twins for epithelial ovarian carcinoma upregulation of the 4 miRNAs, miR-6131, miR-1305, miR-197-3p, miR-3651 and downregulation of 4 miRNAs, miR-3135b, miR-4430, miR-664b-5p, miR-766-3p were found statically significant. CONCLUSIONS The detected 99 miRNAs out of 2549 miRNAs might be used in the clinic as new biological indicators in the diagnosis and follow up of epithelial ovarian cancer with complementary studies. The miRNA expression profiles were identified to be statistically significant in the evaluation of ovarian cancer etiology, BRCA1 mutation status, and ovarian cancer risk in accordance with the obtained data. There is a need for validation of the miRNAs which were particularly detected between monozygotic twins and its association with ovarian cancer was emphasized in our study in wider cohorts including ovarian cancer patients, and healthy individuals.

Abstract
Both uterine serous carcinoma (USC) and ovarian serous carcinoma (OSC) are presented at advanced stage at the first admittion and dissseminated disease makes the anatomical site of the tumor origin imposible. CA125 and p53 are reliable markers that are useful for differentiating both uterine serous and ovarian serous carcinoma from their most common subtypes (endometrioid type carcinoma of ovary and uterus) but so far there is no histopathologic marker that differentiates USC from OSC. On the other hand, Trastuzumab (Herceptin) increases progression-free survival among USC patients, but not OSC patients and makes the histopathologically assigning the origin of the tumor important. So, the aim of this study was to evaluate the immunohistopathological discriminative value of the human epididymis secretory protein 4 (HE4) between OSC and USC patients. Patients with a diagnosis of OSC and UTC were enrolled. HE4 expression was evaluated by immunohistochemistry. The results were compared between groups. Of the tumor tissues studied, HE4 immunostaining was seen in the majority of ovarian serous carcinoma cases (89.65%), while endomatrial serous carcinoma cases were devoid of HE4 immunostaining. HE4 immunostaining was seen in 39.1% uterin serous carcinoma cases and this difference was statistically significant (p = 0.001). Our study demonstrated for the first time the potential of HE4 expression to predict the anatomical site of tumor origin. HE4 is a novel tumor marker that differentiates USC from OSC.

Abstract
INTRODUCTION Acinetobacter baumannii is an opportunistic pathogen that causes nosocomial infections with high mortality. Treatment options are limited owing to its resistance to numerous antibiotics. Here, we sought to determine the antibiotic susceptibilities of A. baumannii isolates, investigate clonal relationship among the strains, and determine the frequency of beta-lactamase resistance genes. METHODOLOGY The identification and antibiotic susceptibilities of 69 A. baumannii strains were determined using a BD-Phoenix automated system. The presence of blaOXA-2, blaOXA-10, blaOXA-23, blaOXA-24/40, blaOXA-51, blaOXA-58, blaTEM, blaSHV, blaIMP, blaVIM, and blaGIM genes were investigated using polymerase chain reaction (PCR), and clonal relatioships among the isolates were determined using pulsed-field gel electrophoresis (PFGE). RESULTS All strains were resistant to ampicillin-sulbactam, gentamicin, cefepime, ciprofloxacin, and ceftriaxone. While 65 of the 69 strains (94.2%) were resistant to piperacillin-tazobactam, amikacin, imipenem, and meropenem, all strains were susceptible to tigecycline and colistin. The frequencies of blaOXA-51, blaOXA-23, blaTEM, blaOXA-2, blaVIM, and blaSHV were 100%, 94.2%, 53.6%, 21.7%, 14.5%, and 2.9%, respectively. Based on PFGE results, 56 of the 69 strains were clonally related, and the clustering rate was 81.2%. No common outbreak isolate was detected. CONCLUSIONS The most prevalent OXA genes were blaOXA-51, blaOXA-23, and blaOXA-2. Furthermore, blaTEM, blaSHV, and blaVIM, which are common in Enterobacterales and Pseudomonas spp, were detected, suggesting horizontal gene transfer had occurred between bacteria. No single clone outbreak was detected by PFGE. However, multiclonal spread and the high clustering rate suggest cross-contamination. Therefore, in future, more effective infection control measures must be implemented.

Abstract
BACKGROUND Retinoblastoma (Rb) is the most prevalent intraocular pediatric malignancy of the retina. Significant genetic factors are known to have a role in the development of Rb. METHODS Here, we report the mutation status of 4813 clinically significant genes in six patients with noncarrier of RB1 gene mutation and having normal RB1 promoter methylation from three families having higher risk for developing Rb in the study. RESULTS A total of 27 variants were detected in the study. Heterozygous missense variants c.1162G > A (p.Gly388Arg) in the FGFR4 gene; c.559C > T (p.Pro187Ser) in the NQO1 gene were identified. The family based evaluation of the variants showed that the variant, c.714T > G (p.Tyr238Ter), in the CLEC7A gene in first family; the variant, c.55C > T (p.Arg19Ter), in the APOC3 gene and the variant, c.1171C > T (p.Gln391Ter), in the MUTYH gene in second family; and the variant, c.211G > A (p.Gly71Arg), in the UGT1A1 gene in the third family, were found statistically significant (p < 0.05). CONCLUSION This study might be an important report on emphazing the mutational status of other genes in patients without RB1 gene mutations and having high risk for developing Rb. The study also indicates the interaction between the retinoic acid pathway and Rb oncogenesis for the first time.

Abstract
Acute pulmonary embolism (PE) is an uncommon clinical condition in childhood. We hereby present a case report of a 10-year-old child who presented to the emergency department with an acute massive PE. He was transferred by ambulance to our emergency department for dyspnea and perioral cyanosis. His parents denied any previous history of illness or familial disease. Arterial blood gas analysis, electrocardiography, and clinical symptoms and signs collectively raised a suspicion of a probable PE. A contrast-enhanced pulmonary computed tomography scan revealed a massive thrombus in the distal part of the right pulmonary artery with no contrast passage into upper, middle, and lower lobar arteries. Upon ascertaining, the diagnosis of PE, intravenous saline infusion, 3 L/min oxygen through nasal route, and subcutaneous enoxaparin 0.4 cc was administered promptly. As our hospital lacked a pediatric intensive care unit and a further need for administration of pharmacological thrombolysis was anticipated, we transferred the patient to a tertiary care center. PE should always be kept in mind as a differential diagnosis in emergency departments even in pediatric patients.

Abstract
Aim Cancer diagnosis and treatment depend on pathology reports but naming a cancer is sometimes impossible without specialized techniques. We aimed to evaluate the sensitivity of cytological sub-classification of non-small cell lung carcinoma, not otherwise specified group (NSCLC-NOS) into Adenocarcinoma (AC) and Squamous cell carcinoma (SqCC) without using immunohistochemistry. Methods Endobronchial ultrasound guided fine-needle aspiration biopsies and cytology slides diagnosed as NSCLC-NOS between 2004- 2008 were reviewed retrospectively. The final diagnosis was reached by immunohistochemistry (TTF-1, p63) when necessary. Results One hundred-twenty nine cases were retrieved. The final diagnoses were as follows: SqCC: 30.3%; AC: 65.7%; combined tumor (3 adenosquamous and 1 small cell + SqCC): 4%. Cytological diagnoses rendered were as follow: Definitely SqCC: 10.1%; favor SqCC: 14.1%; definitely AC: 38.4%; favor AC: 35.4%; NSCLC-NOS: 2%. The sensitivity and specificity of cytology were 86.3 and 87.5% for AC diagnosis respectively. Conclusion Positive and negative predictive value of cytology was 95.3% and it was even 100% for well to moderately differentiated tumors. There was a tendency to sub-classify poorly differentiated SqCC as AC. Papanicolaou stain increased the diagnostic accuracy of SqCC. The combined tumor rate was 4% and after recognizing a tumor component, the second component was missed if the slide examination was terminated prematurely.

Abstract
Dermatofibromas are common lesions of the skin. Although they occur at any part of the body, they are most commonly observed on the lower legs of middle-aged women. The lesion comprises fibroblast-like cells, histiocytes, collagenous tissue, and blood vessels. Many histological variants have been defined based on the ratio of cell components and their location. These variants of dermatofibroma may cause problems during differential diagnosis between benign and malignant mesenchymal lesions of the skin and may lead pathologists to overdiagnose this lesion. Here, we report a case of clear cell dermatofibroma, which is a rare variant of dermatofibroma, together with its diagnostic traps.

Abstract
Human epididymis protein 4 (HE4) acts as a protease inhibitor. It has been detected in the serum of patients with lung cancer patients and its utility for lung cancer screening was found in different studies. Nevertheless, little is known regarding the expression of HE4 in lung carcinoma subtypes. The aim of the present study was to investigate whether HE4 expression is a reliable marker for detecting any lung carcinoma subtypes, including small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC) and adenocarcinoma (AC). In total, 141 lung carcinoma patients were enrolled in the study. Biopsy samples were obtained from bronchoscopic biopsy. The tumors were classified as SCLC (group 1, 54 cases) or NSCLC (group 2, 87 cases) based on histology and immunohistochemistry. The latter was sub-grouped as adenocarcinoma (group 2a, AC) and squamous cell carcinoma (group 2b, SCC). The immunohistochemical expression of HE4 was compared between the groups. The study revealed that the majority of the SCLC and SCC cases were devoid of HE4 (90.1 and 89.65%, respectively). Approximately 10% of cases had HE4 immune expression and the staining was focal and moderate throughout the tumor tissue. On the other hand, 78.8% of AC expressed HE4 and the staining was diffuse and strong. The overall HE4 expression in the lung cancer patients was 33.7%. In conclusion, the results of the present study have shown that HE4 is expressed in adenocarcinoma of the lung but it is not frequent in SCC and SCLC. The value of HE4 as a screening biomarker for lung cancer is limited but its presence exclusively in adenocarcinoma may provide new insight for targeted therapy.

Abstract
In this study, associations between IL-4, IL-6, and macrophage migration inhibitory factor (MIF) polymorphisms and susceptibility to brucellosis were investigated. Consecutive adult patients with no known treatment against brucellosis and who did not have any other autoimmune and/or chronic disorders, were included in this study (n = 120, Group I). Age and sex-matched controls who had no other autoimmune and/or chronic disorders were also included (n = 120, healthy volunteers, Group II). The IL4_P2P2 genotype, IL4_P1 allele, and IL4_variable number of tandem repeats (VNTR)_IL6-174CG compound genotype were found to be more frequent in the patient group than in control subjects. There were significant differences between the patients and controls with respect to the frequencies of the IL4_P2P2 genotype (77.5% versus 87.5%; p = 0.001; OR, 0.36; 95% confidence interval [CI], 0.21-0.62) and the IL4_P1 allele (12.1% versus 6.7%; p = 0.030; OR, 0.92; CI, 1.02-3.64). The IL4-VNTR_IL6-174CG compound genotype was also present at a significantly higher frequency in the patient group than in control subjects (11.7% versus 4.2%; p = 0.027, OR, 3.04; CI, 1.06-8.68). No statistically significant differences in the frequencies of the IL-6-174, MIF-173, IL-4_P1P1, and IL4_P2P1 genotypes were observed between patients and control subjects. The IL4_VNTR P1 allele, P2P2 genotypes, and IL4-VNTR_IL6-174CG P2P1-GG genotypes are common in southern Turkey, and carriers of these polymorphisms are susceptible to brucellosis.

Abstract
BACKGROUND Toxic epidermal necrolysis (TEN) is characterized by widespread erythematous and bullous lesions on the skin. Nowadays, considerable progress has been made in the understanding of its pathogenesis. Immunologically it is similar to graft-versus-host disease. Therefore, we may propose that TEN is a disorder of cell-mediated immunity. CASE REPORT Our patient was a 74-year-old white female who had pneumonia and was positive for hepatitis C virus (HCV), and who had been on levofloxacin therapy. After the first levofloxacin dose, erythematous dusky red macules occurred on her extremities and trunk, and on the following day, confluent purpuric lesions tended to run together over 85% of her body. Her biopsy results indicated TEN. Laboratory testing for serum ECP (eosinophil cationic peptide) and serum immunoglobulin (Ig) levels were performed, and blister fluid was investigated. The patient responded positively to omalizumab treatment and after treatment laboratory tests revealed decreased high sensitive CRP, ECP, IgG1, IgG2, IgG3, IgG4, IgA, and IgM levels. CONCLUSIONS To the best of our knowledge, this is the first case of a patient with HCV who developed cutaneous adverse drug reaction on levofloxacin medication and recovered with omalizumab treatment. This is the first documentation of omalizumab treatment of a TEN patient.

Abstract
The influence of biomarkers on carcinogenesis has been investigated extensively. Whether they promote carcinogenesis or work against cancer development remains to be elucidated. To the best of our knowledge, the novel molecule cluster of differentiation 200 (CD200) has not been studied on human breast cancer subjects. The present study aimed to evaluate interleukin-1β (IL-1β), C-X-C motif chemokine ligand 8 (CXCL8), cancer antigen 15.3 (CA 15.3) and the soluble CD200 (sCD200) levels in the serum samples of breast carcinoma patients in order to predict their role in breast carcinoma. The subjects included individuals with early and advanced stage breast cancers, as well as healthy controls. Commercially available ELISA kits were used to measure the serum concentrations of sCD200, IL-1β, CXCL8, CA 15.3, C-reactive protein (CRP) and leukocyte count. A total of 130 subjects were recruited; 50 early stage cancer, 50 advanced stage and 30 control subjects. Serum sCD200, CXCL8, IL-1β and CRP levels were significantly higher in the early as well as the advanced stage breast cancer patients compared to the control group. The level of CA 15.3 was statistically different between early and advanced stage. There were significant positive correlations between IL-1β and CXCL8, and IL-1β and serum sCD200 levels in the control group. These correlations did not persist in the early or the advanced stage cancer groups except CRP and CA 15.3, but new correlations appeared between serum sCD200 level and leukocyte count for advanced stage breast cancer group. Multivariate regression correlation analysis revealed positive correlation between IL-1β and sCD200; and IL-1β and CXCL8. In conclusion, sCD200, CXCL8, CA 15.3 and IL-1β are proinflammatory molecules and their levels are influenced in breast cancer patients.

Abstract
CONTEXT The term "asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome" (ACOS) has been applied to the condition, in which a person has clinical features of both asthma and COPD. METHODS The patients (N = 10) were presented to our clinic with low lung function, limited reversibility of airway obstruction, hyperinflation, abnormal body composition, dyspnea and episodic wheezing. Based on the clinical and laboratory findings, the patients were diagnosed with ACOS. Patients' serum IL-2 (sIL-2), sIL-4 sIL-6, sIL-10, sIL-17, sTNF-α and sIFN-γ levels were investigated as an apoptotic marker and a marker for inflammation. RESULTS Having undergone omalizumab treatment and a long-term (12 months) later, patients had a decreased IgE, fractional exhaled nitric oxide concentrations (FENO), eosinophil, neutrophils, macrophages, eosinophil cationic peptide (ECP) and sIL-4 levels. CONCLUSION To our knowledge, this is the first documentation of omalizumab use in ACOS. We demonstrated decreased IL-4, allergic pulmonary symptoms (dyspnea, wheezing, bronchial hyper responsiveness) and migraine attacks in the patients.

Abstract
BACKGROUND Thyroid fine-needle aspiration (FNA) is used to assess appropriate management of nodular thyroid lesions safely, but Bethesda category III (atypia of undetermined significance/follicular lesion of undetermined significance) and category IV (follicular neoplasm/suspicious for follicular neoplasm) lesions are problematic. This study aimed to evaluate the Afirma Gene Expression Classifier (GEC) results for lesions in those categories. METHODS Medical records of patients with thyroid FNA and GEC results were obtained from archived material. Results were compared to thyroidectomy histologic diagnoses. RESULTS Among 66 patients with FNA results (47 women and 19 men aged 26-89 years [mean, 59.4 years]), surgical reports were available for 38. Afirma GEC results were "nondiagnostic" for 10 of 66 (15.2%), "benign" for 22 (33.3%), and "suspicious" for 34 (51.5%). Surgical diagnosis was available for 38 of 66 patients (57.6%); GEC results for 6 (15.8%) of these were "nondiagnostic," 27 (71.0%) were "suspicious," and 5 (13.2%) were "benign." One of 6 (16.7%) samples with "nondiagnostic" results, 1 of 5 (20%) with "benign" results, and 15 of 27 (55.6%) with "suspicious" results were malignant on histology. Papillary carcinoma was the most common tumor type (15 of 38; 39.5%). CONCLUSIONS Afirma GEC results minimize the number of unnecessary operations. Afirma GEC testing may be reserved for FNAs with a category III diagnosis on follow-up cytologic examination. We recommend a conservative approach for "suspicious" Afirma GEC results if Hürthle cells are seen with FNA.

Abstract
STUDY DESIGN Case report. OBJECTIVE To describe a case of testicular torsion in spinal cord injury (SCI). SETTING Physical Medicine Rehabilitation Training and Research Hospital in Turkey. METHODS We present the first case of testicular torsion in SCI along with its clinical presentation and follow-up results. RESULTS Testicular torsion is a rare condition. No case was reported in people with SCI so far. The main difficulty in the diagnosis is that the nociceptive pain is below the injury level and the acute condition could be overlooked. CONCLUSION Testicular torsion is an acute condition for which early diagnosis is critical in the treatment. The case we describe adds new pitfalls in the diagnosis of this rare condition in people with SCI from the perspective of nociceptive pain below the injury level.

Abstract
OBJECTIVES Studies on sCD200 (OX-2), 25-hydroxyvitamin-D (25(OH)D), homocysteine (hcy), eosinophil cationic peptide (ECP), d-dimer, CXCL8 and fractional exhale nitric oxide concentrations in allergic patients in Mediterranean regions under various climatic conditions have not been performed. In this report, blood samples were taken in May and June during times of high air pollination. This study was performed to compare serum biomolecule concentrations in allergic patients and matched controls and to evaluate the characteristics of allergic disease. METHODS The study participants (n = 129) included 25 healthy individuals (controls) and 104 allergic patients. Consecutive patients with managed allergic disease (Group II, III, IV and V) above the age of 18 years were included. RESULTS In the control group, there was a significant positive correlation between ECP level and body mass index (BMI). Positive correlations among ECP, IgE and OX-2 levels were detected in Group IV. In Group V patients, positive correlations between age and IgE and between BMI and 25(OH)D were identified. Statistical analysis revealed positive correlations among basophil, eosinophil and OX-2 levels, and a negative correlation between ECP and age in Group V. CONCLUSION Overall, these data suggest that hcy, 25(OH)D and OX-2 may be useful biomarkers for conventional clinical measurements.

Abstract
PURPOSE The purpose of this study was to evaluate the soluble Apo-2L (sApo-2L) levels in the ascitic fluid and to study its potential in detecting malignant ascites and soluble CD200 (sCD200,sOX-2) levels so as to predict its clinical usage for detecting stage 4 metastatic endometrial, ovarian and breast cancer in serum samples. METHODS Ascitic fluid from 53 and blood from 25 subjects without known malignancy on admission were collected. There were 14 breast cancer (BC), 17 ovarian cancer (OC) and 19 endometrial cancer (EC) patients diagnosed later on. Blood samples for sApo-2L, sCD200, liver function tests and CEA, CA-19.9 and CA-125 were always taken and assayed in the morning. RESULTS Significantly low levels of sApo-2L were observed in peritoneal fluid from OC and EC patients compared to benign peritoneal fluid from control individuals. Positive correlation was observed between sApo-2L and aspartate aminotransferase (AST) in benign peritoneal fluid and sCD200, and creatinine and sCD200 and platelets in OC patients; also, sCD200 and CEA in EC patients and sCD200 and blood urea nitrogen (BUN) in healthy subjects. CONCLUSIONS Our data indicate that low proteomics pattern of sApo-2L but not sCD200 is a good biochemical marker. Further decline in the level of sApo-2L was seen in EC compared to OC. Since higher levels of sApo-2L were seen with higher levels of AST, the liver might be involved in its metabolism. The positive correlation detected between sCD200 and creatinine, platelets, CEA and BUN needs to be elucidated.

Abstract
Radial scars (RSs) or complex sclerosing lesions (CSLs) of the breast are benign radiologic and histologic entities. With the introduction of population-based screening programs, their incidence has increased to 0.03% to 0.09% of all core needle biopsies (CNBs). They can pose diagnostic difficulty because their radiologic and histologic appearances mimic carcinoma. We retrospectively searched for and reviewed all cases of RS/CSL diagnosed on image-guided CNB from January 1, 1994, to August 31, 2013, at a single institution. We also assessed the pathologic reports from excisional biopsies to identify cases upstaged to atypia or neoplasm. After exclusions, 100 CNBs were identified from 97 women, which showed RS/CSL without concomitant atypia. Mean age of the women was 52.9 years. Thirty-five women (38/100 CNBs, 38%) had follow-up excision. The median size of the excised RS/CSLs was 1.2 cm; 69% were larger than 1.0 cm. Almost all excised cases (92%) showed radiologic and pathologic concordance, and 79% were designated as suspicious for malignancy (Breast Imaging Reporting and Data System level 4). The most common findings of 38 follow-up excisional biopsies were residual RS (22 [58%]), atypical lobular hyperplasia (5 [13%]), and no residual lesion (5 [13%]). Eleven excisional biopsies (29%) were upstaged to invasive or in situ carcinoma or to atypical hyperplasia. Follow-up excisional biopsy is warranted for RS/CSLs, specifically those larger than 1.0 cm with worrisome radiographic findings or with radiologic and pathologic discordance. Approximately 29% of cases were upstaged to in situ or invasive carcinomas or other high-risk lesions in our study.

Abstract
Pro-inflammatory factors regulated by TRAIL in vivo may lead to the development of novel therapeutic strategies for diseases as diverse as infection, autoimmunity and allergy. In this study we aimed to investigate the relationship between IFN treatment response, HCV viral load and sApo 2L levels. Eleven HCV-treatment naive HCV-infected patients were treated with pegIFN alfa-2a. Intensive serum circulating Apo 2L levels were monitored at study visits on day 0 (pretreatment), and in weeks 4, 6 and 12. HCV-RNA and sApo 2L levels decreased gradually with PegIF-alfa 2 treatment and the differences were significant between day 0 and week 4 (p 0.001, p 0.005 and p 0.01, p 0.005 respectively); between day 0 and week 12 (p 0.001, p 0.005 and p 0.001, p 0.000 respectively); between weeks 6 and 12 (p 0.01, p 0.05 and p 0.01, p 0.05 respectively). We suggest that decreased levels of circulating Apo 2L may reflect its increased binding to its ligand expressed on hepatocytes or lymphocytes under the influence of PegIFN treatment.

Abstract
OBJECTIVES The D-dimer level, fibrinogen level, and D-dimer/fibrinogen ratio are used in the diagnosis of pulmonary embolism, but results vary. We evaluated these parameters in the diagnosis of pulmonary embolism in emergency clinic patients. METHODS In this prospective study, 200 patients (pulmonary embolism, 100 patients; no pulmonary embolism, 100 patients) had D-dimer and fibrinogen levels measured before intervention. Pulmonary embolism was diagnosed with computed tomography angiography or ventilation-perfusion scintigraphy. RESULTS Compared with patients who did not have pulmonary embolism, patients who had pulmonary embolism had significantly greater mean D-dimer level (pulmonary embolism, 6±7 μg/ml; no pulmonary embolism, 1±1 μg/ml; P⩽0·001) and D-dimer/fibrinogen ratio (pulmonary embolism, 3±3; no pulmonary embolism, 0·4±0·4; P⩽0·001), but similar mean fibrinogen levels (pulmonary embolism, 337±184 mg/dl; no pulmonary embolism, 384±200 mg/dl; not significant). In patients who had pulmonary embolism, mean D-dimer level and D-dimer/fibrinogen ratio were greater in high-risk than non-high-risk patients. With D-dimer cutoff 0·35 μg/ml, sensitivity was high (100%) and specificity was low (27%) for pulmonary embolism. With D-dimer/fibrinogen ratio cutoff 0·13, sensitivity was high (100%) and specificity was low (37%) for pulmonary embolism. CONCLUSION A D-dimer level <0·35 μg/ml may exclude the diagnosis of pulmonary embolism. At a D-dimer cutoff 0·5 μg/ml and D-dimer/fibrinogen ratio cutoff 1·0, the D-dimer/fibrinogen ratio may have better specificity than D-dimer level in the diagnosis of pulmonary embolism, but the D-dimer/fibrinogen ratio may lack sufficient specificity in screening.

Abstract
BACKGROUND CD200 (OX-2) is a novel immune-effective molecule, existing in a cell membrane-bound form, as well as in a soluble form in serum (s OX-2), which acts to regulate inflammatory and acquired immune responses. MATERIAL AND METHODS We planned this study to evaluate the sOX-2 levels of type 2 diabetic foot (group B), and compare it with that of healthy controls (group A). The patient group had the following values: DM period: 27.9±10.3 year [mean ±SD], HbA1c: 9.52±2.44% [mean ±SD]. RESULTS Blood samples for sCD200 measurement were always taken in the morning between 8 and 10 A.M.. The results were reported as means of duplicate measurements. Concentrations of sOX-2 in the serum samples were quantified using an ELISA kit. Serum hs-CRP levels were measured using an hs-CRP assay kit. The sOX-2 level in group B was 173.8±3.1 and in group A was 70.52±1.2 [p<0.0001). In subgroup analysis of T2DM-DFI patients, we noticed that sOX-2 levels were higher in WGS (Wagner grading system) I and II patients than in WGS III and IV patients. The HbA1c, BUN, creatinine, hs-CRP levels, and sedimentation rates were higher in the patient group (p<0.0001, p<0.001, p<0.001, p<0.005, and p<0.0001, respectively). CONCLUSIONS We suggest that there are vascular, immunologic, and neurologic components in DFI, whereas autoimmune diseases and inflammatory skin disorders have only an immunologic component. This is possibly evidence of a pro-inflammatory effect seen in DFI as a vascular complication.

Abstract
Our objective was to evaluate the diagnostic yield of rapid on-site evaluation (ROSE) on the differential diagnosis of non-small cell lung carcinoma, not otherwise specified (NSCLC-NOS). Biopsied cases diagnosed as NSCLC-NOS with ROSE during 2004 through 2008 were retrieved. Diagnostic confirmation was done with immunohistochemistry (IHC) involving thyroid transcription factor-1 and p63 immunostains. For the study, 106 cases were available. The final diagnoses rendered were squamous cell carcinoma (SqCC) (n = 39) and adenocarcinoma (AC) (n = 67). Cytologic, histologic, and IHC concordance for these diagnoses occurred in 75 cases (70.8 %), of which 56 (52.8%) were AC and 19 (17.9%) were SqCC. Cytologic, histologic, and IHC discordance was found in 31 cases (29.2%). Of these 31 cases, 11 NSCLC-NOS diagnoses histologically corresponded to 1 SqCC plus 4 ACs, and 4 favor SqCC plus 2 ACs; the former 5 NSCLC-NOS cases classified correctly through cytology, as well as IHC. However, IHC was not available for the latter 6 NSCLC-NOS cases that were also classified correctly through cytology. In addition, only 3 NSCLC-NOS diagnoses cytologically corresponded to 3 favor SqCC histologically, in which IHC was not available, and for 2 cases that both corresponded to favor SqCC and favor AC histologically and cytologically. In the other 15 cases, histology labeled 4 cases NSCLC-NOS and misclassified 2 cases; cytology labeled 1 case NSCLC-NOS and misclassified 13 cases. ROSE has high diagnostic yield over subclassification of NSCLC-NOS. We recommend allocating a cytotechnologist for specimen adequacy and a cytopathologist for cytologic diagnosis.
