Abstract
BACKGROUND Platelet-rich plasma (PRP) is an autologous concentration of human platelets contained in a small volume of plasma and has recently been shown to accelerate rejuvenate aging skin by various growth factors and cell adhesion molecules. OBJECTIVE This study was conducted to evaluate the efficacy and safety of intradermal injection of PRP in the human facial rejuvenation. METHODS This study was a prospective, single-center, single-dose, open-label, non-randomized controlled clinical study. PRP injected to the upper site of this right infra-auricular area and all face. Saline was injected to the left infra-auricular area. Histopathological examinations were performed before PRP treatment, 28 days after the PRP, and saline (control) treatments. RESULTS Twenty women ranging in age from 40 to 49 years (mean age, 43.65±2.43 years) were enrolled in the study. The mean optical densities (MODs) of collagen in the pre-treatment, control, and PRP-treated area were measured. They were 539±93.2, 787±134.15, 1,019±178, respectively. In the MOD of PRP, 89.05 percent improvement was found when MOD of PRP was compared with MOD of pre-treatment. The mean MOD of collagen fibers was clearly highest on the PRP side (p<0.001). The PRP-to-saline improvement ratio (89.05% to 46.01%) was 1.93:1. No serious side effects were detected. CONCLUSION PRP increases dermal collagen levels not only by growth factors, but also by skin needling (the mesotherapy technique 'point by point'). PRP application could be considered as an effective (even a single application) and safety procedure for facial skin rejuvenation.

Abstract
The functional role of IGFBP5 in breast cancer is complicated. Experimental and
bioinformatics studies have shown that IGFBP5 is targeted by miR-140-5p and miR-193b,
although this has not yet been proven in clinical samples. The aim of this study was
to evaluate the expression of miR-140-5p and miR-193b in breast cancer and adjacent
normal tissue and assess its correlation with IGFBP5 and the clinicopathological
characteristics of the tumors. IGFBP5 protein expression was analyzed
immunohistochemically and IGFBP5, miR-140 and miR-193b mRNA expression levels were
analyzed with real-time RT-PCR. Tumor tissue had higher miR-140-5p expression than
adjacent normal tissue (p = 0.015). Samples with no immunohistochemical staining for
IGFBP5 showed increased miR-140-5p expression (p = 0.009). miR-140-5p expression was
elevated in invasive ductal carcinomas (p = 0.002), whereas basal-like tumors had
decreased expression of miR-140-5p compared to other tumors (p = 0.008). Lymph
node-positive samples showed an approximately 13-fold increase in miR-140-5p
expression compared to lymph node-negative tissue (p = 0.049). These findings suggest
that miR-140-5p, but not miR-193b, could be an important determinant of IGFBP5
expression and clinical phenotype in breast cancer patients. Further studies are
needed to clarify the expressional regulation of IGFBP5 by miR-140-5p.

Abstract
In spite of the fact that an indirect relationship between NEIL1 gene and Type 2 diabetes has been demonstrated in animal model studies, there have been no human studies showing this relationship. In our study, we aimed to show the relationship between NEIL1 mutation and Type 2 diabetes in humans. The study group consisted 70 patients with Type 2 diabetes and the control group consisted of 50 healthy individuals. The mean age was 53±11 yr and 49±11 yr, respectively. Two NEIL1 mutations (2.9%) were detected in the patient group. There was A→G change (133A→G) at the 133. position of the 8th exon with 257 bp length in base sequencing. There was no mutation in the control group. We searched NEIL1 gene mutation for the first time in patients with Type 2 diabetes. This mutation was "silent" as it did not cause any amino acid change. The effects of these mutations on the etiopathogenesis of disease are not known. Although the lysine encoded by AAG was identical to the lysine encoded by AAA, it is not clear if they have functional differences due to the changing environmental conditions. NEIL1 gene mutation may have causative role in the development of Type 2 diabetes.

Abstract
Recently, efforts have been focused on mitochondrial DNA changes and their relation to human cancers. Among them, a 4977 bp deletion of mitochondrial DNA, named “common deletion”, has been investigated in several types of tumors, with inconsistent results. In this study, we investigated the presence of the common deletion in tissues from 25 breast, 25 colorectal and 50 thyroid tumors and in the adjacent healthy tissues from Turkish patients. Samples from healthy volunteers were also evaluated for comparison. Two PCR-based methods were used for the detection of the common deletion. First, two pairs of primers were used to amplify wild-type and deleted mtDNA. Then, a highly sensitive nested-PCR was performed, to determine low amounts of deleted genomes. By the first method, wild-type mtDNAs were observed in all samples, but a deletion was observed in only six thyroid samples, by using the nested-PCR method. In conclusion, the mitochondrial common deletion was very rare in our study group and did not appear to be not related with cancer.

Abstract
OBJECTIVE Investigations for risk definition in endometrial lesion spectrum still go on. In this study, molecular, morphometric, immunohistochemical techniques were combined with conventional morphology to realize whether an algorithm is definable for risk assessment to progress an invasive carcinoma in endometrial glandular lesion spectrum is possible. METHODS The study was carried out on 20 benign endometria, 35 hyperplasias, and 20 adenocarcinoma cases. Clonality of glandular cells, the volume percent of endometrial stroma (VPS), PTEN inactivation, and proliferative index (PI) were evaluated. Statistical analysis was evaluated to set an objective algorithm. RESULTS All benign tissues had polyclonal (PC), whereas all malignant tissues had monoclonal (MC) glandular epithelium. Of hyperplasias, 19 were MC, and 16 were PC. VPS value of 55% had 100% sensitivity, and 80% specificity (n=67) to distinguish MC from PC. Neither PTEN nor PI data augmented the specificity or the sensitivity of clonal distinction. CONCLUSION Clonality and VPS values were found to be significant in differential of endometrial lesions. With this rationale, a diagnostic algorithm for endometrial risk lesions was set. This algorithm is based on HE morphology, VPS and clonality findings, and has 100% sensitivity and specificity to discriminate neoplastic endometrium from hyperplasia.

Abstract
PURPOSE To determine the prevalence and type of human papilloma virus deoxyribonucleic acid (DNA) in cases of laryngeal squamous cell carcinoma. METHODS We analysed the prevalence of human papilloma virus infection in archived paraffin block specimens taken from 99 cases of laryngeal squamous cell carcinoma between 1990 and 2005, using polymerase chain reaction techniques. Biopsy specimens from five proven verrucous skin lesions were used as positive controls, and peripheral blood samples from five healthy volunteers were used as negative controls. RESULTS Four test samples were found to have inadequate deoxyribonucleic acid purity and were therefore excluded from the study. Human papilloma virus deoxyribonucleic acid was detected in seven of 95 cases of laryngeal squamous cell carcinoma (7.36 per cent). Human papilloma virus genotyping revealed double human papilloma virus infection in three cases and single human papilloma virus infection in the remaining four cases. The human papilloma virus genotypes detected were 6, 11 and 16 (the latter detected in only one case). CONCLUSION In our series, a very low human papilloma virus prevalence was found among laryngeal squamous cell carcinoma cases. The human papilloma virus genotypes detected were mostly 6 and/or 11, and 16 in only one case. To the best of our knowledge, this is the first report of human papilloma virus prevalence in laryngeal squamous cell carcinoma, based on polymerase chain reaction genotyping in a Turkish population.

Abstract
We assessed the diagnostic value of the 14C urea breath test (UBT) in the detection of Helicobacter pylori compared with histology and the rapid urease test (RUT). The study included 68 patients (22 men and 46 women) with dyspeptic symptoms. H. pylori status was evaluated by 14C UBT, RUT and histology. Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy were determined for 14C UBT and for RUT. Histology revealed dense yeast-like micro-organisms in the biopsy specimens in all patients with false-positive results by 14C UBT (n = 8), a significantly higher proportion than in patients with negative 14C UBT (five of 31). The low specificity of the H. pylori 14C UBT should not be neglected by accepting histology results as false-negative. Gastric mucosal colonization by yeast-like micro-organisms with urease activity can account for the high frequency of false-positive results for 14C UBT.

Abstract
PURPOSE To evaluate the histopathologic impact of dacryocystorhinostomy (DCR) and silicone intubation on the lacrimal sac. METHODS Biopsy materials were taken from the sac wall and fixed (primary biopsy) in 224 patients undergoing DCR between 1995 and 2003 in our institution. A total of 23 patients underwent a second operation as the result of restenosis, and a secondary biopsy specimen was taken from the sac wall. During the initial operation, DCR and silicone intubation were combined in 13 patients (group 1), and only DCR without silicone intubation was performed in 10% patients (group 2). The histopathologic findings of the primary and secondary biopsy specimens were compared in these 23 recurrent cases. In addition, the secondary biopsy findings in the intubation and nonintubation groups were compared to determine the possible effects of the silicone intubation on the sac mucosa. RESULTS Endonasal examination of restenosis cases revealed macroscopic cicatrization. One of the cases with silicone intubation had pyogenic granuloma and two had polypoid granulation tissue at the site of anastomosis. Inflammatory polypoid development at the site of anastomosis was also observed in one case without intubation. The primary biopsy specimens of those 23 patients undergoing a second operation revealed the following findings: chronic inflammatory changes, mild fibrosis, focal ulceration in the epithelium, and a decrease in the number of goblet cells. In the secondary biopsy specimens, 2 patients in group 1 had polypoid granulation tissue, 1 patient had pyogenic granuloma, and 3 patients had exudate reflecting acute inflammation. In group 2, granulation tissue was observed in 1 case, and 2 patients had acute inflammation. There were no differences in the primary and secondary biopsy specimens of the two groups with respect to chronic inflammatory changes, focal ulceration, and the number of goblet cells (p = 0.31; 0.31, 0.65). A marked increase in fibrosis was observed in the secondary biopsy specimens of all cases (p < 0.0001). There were no significant differences between the intubation and the nonintubation groups in terms of secondary biopsy specimens (p > 0.05). CONCLUSIONS The marked increase in the intensity of fibrosis observed in the secondary biopsy specimens of all cases was the result of the tissue repair reaction against surgical manipulation rather than the effect of the silicone tube.

Abstract
In this study, we investigated tissue levels of reduced glutathione (GSH) and carnitine as well as thiobarbituric acid reactive substances (TBARS, as a marker of lipid peroxidation) levels in bladder carcinoma and control group of patients. The average GSH, carnitine and TBARS levels for tumor group were respectively 7.11 +/- 3.3 micro g/mg protein, 1.81 +/- 0.39 nmol/mg protein, and 4.29 +/- 3.2 micro mol/mg protein, versus 14.45 +/- 4.11 micro g/mg protein, 2.14 +/- 0.66 nmol/mg protein, and 2.3 +/- 0.6 micro mol/mg protein for normal bladder tissues. Thus, tissue reduced glutathione levels (GSH) were significantly lower in patients as compared with the control group (p < 0.001) whereas average TBARS levels in the tumor group were found to be higher than those in control group. The average tissue carnitine levels in the patient group were found to be lower compared with the control group but the difference was not statistically significant (p > 0.05).

Abstract
This study was undertaken to determine whether p53 or bcl-2 immunoexpression has any significance in the prognosis of laryngeal squamous cell carcinoma. Eighty-four cases of laryngeal squamous cell carcinoma at different pathological stages and locations were studied. All patients were treated surgically first, and followed up for 6-96 months (mean, 35 months). p53 and bcl-2 immunoexpression in tumour cells, evaluated by image analysis and histoscore, were found in 71.4% and 46.4% of tumours, respectively. Glottic location was correlated with significantly longer survival than tumours at other locations. Pathological stage and histological grade of tumour were also significant predictors of survival. Neither p53 nor bcl-2 immunoexpression was found to be predictive of post-operative survival. Only transglottic tumours expressed significantly high levels of bcl-2. Both methods used to evaluate p53 and bcl-2 immunoexpression correlated well with each other. This study suggests that immunoexpression of p53 and bcl-2 is not a significant prognostic predictor in laryngeal squamous cell carcinoma.

Abstract
Endometrial hyperplasia is a common disorder that is now observed with increasing frequency in women treated with hormonal replacement therapy or with tamoxifen. This study was undertaken to determine whether genomic features of various forms of endometrial hyperplasias would allow their classification as a benign, premalignant, or malignant abnormality. Comparative genomic hybridization (CGH) was performed on endometrial glands microdissected by laser capture microscope from 19 archival endometrial samples, comprising 5 normal endometria, 1 polyp, 2 simple hyperplasias, 5 hyperplasias with nuclear abnormalities (atypical hyperplasias), and 4 low-grade and 2 high-grade endometrioid carcinomas, 1 with squamous component (adenoacanthoma). Genomic DNA, extracted from the glands and the squamous component in 1 case, was amplified by degenerate oligonucleotide-primed polymerase chain reaction (DOP-PCR) and compared with sex-matched DNA by CGH. No genomic imbalances were observed in the normal samples, the polyp, or the simple hyperplasias. However, in atypical hyperplasia, regardless of the level of cytologic atypia, genomic abnormalities were observed that also occurred in endometrioid carcinomas. Chromosomes 1, 8, and 10 were most often affected. The results are compared with molecular genetic abnormalities recently reported in these lesions. This study strongly suggests that atypical endometrial hyperplasias are closely related to endometrioid carcinoma and should be considered precancerous lesions, contrary to simple hyperplasia, which is a benign disorder. The squamous component of one of the high-grade carcinomas showed genetic abnormalities similar to those of endometrioid carcinoma and therefore does not represent squamous metaplasia but is an integral part of the malignant process.

Breast cancer is both one of the most common and one of the most treatable of all human malignancies. It has been suggested by various investigators that sialic acid increases in the sera of cancerous patients. In cancer patients, an increase in the levels of serum sialic acid may also be due to an increase in the activity of serum or tissue sialidase. The purpose of the present investigation was to determine whether the concentration of sialidase in serum and breast tissue could be used as a tumor marker in breast cancer. In this study; serum sialidase levels in 26 patient with breast cancer and 31 controls were found to be 77.04+/-25.07 U/l and 55.56+/-7.50 U/l, respectively. The mean tissue sialidase levels in 26 breast cancer patients and 13 controls were 39.76+/-17.03 U/g protein and 14.30+/-7.09 U/g protein, respectively. Serum and tissue sialidase levels in breast cancer were significantly higher than those found in the control group (P < 0.001). The mean serum and tissue sialidase levels in 14 Grade I-II and 12 Grade III breast cancer patients were found to be 67.73+/-11.87 U/l and 33.41+/-12.17 U/g protein and 87.89+/-31.94 U/l and 47.17+/-19.30 U/g protein, respectively. Also we found a significant difference between the levels of serum and tissue sialidase in Grade I-II and III (P < 0.05).

Abstract
BACKGROUND Knowledge of splanchinic hemodynamics in celiac disease is scarce. The hemodynamic parameters of the superior mesenteric artery were evaluated by duplex Doppler ultrasonography in children with celiac disease to show whether histomorphologic changes in small bowel mucosa led to any alteration in splanchinic blood flow. METHODS The hemodynamic parameters of the superior mesenteric artery were evaluated by Doppler ultrasonography in 23 children with celiac disease. Ten patients were studied at the time of diagnosis. The remaining 13 children were studied after complete clinical and histologic recovery induced by gluten-free diet. Additionally, 9 patients out of 13 who were on a gluten-free diet for about 2 years were given gluten challenge, and superior mesenteric artery blood flow was measured after the challenge. The results were compared with those of healthy children. RESULTS Peak systolic velocity of the superior mesenteric artery was higher in untreated celiac patients than in healthy controls and treated celiac patients. Peak systolic velocity of the superior mesenteric artery in the treated group of children was close to that of control subjects, implying that successful treatment with gluten-free diet improves hemodynamic changes. The comparison of Doppler ultrasonographic measurements of the challenge group before and after the gluten challenge revealed that the peak systolic velocity, resistive index, and blood flow of the superior mesenteric artery were changed significantly. CONCLUSIONS The pathophysiologic events in small bowel mucosa during the active phase of celiac disease induce some hemodynamic changes that can be detected noninvasively by duplex Doppler ultrasonography.

Abstract
OBJECTIVE To determine the value of cytochemical stains and microscopic techniques for the detection of true hydatid elements (primary cytologic criteria) and to evaluate the efficacy of granulomatous elements (secondary cytologic criteria) for the diagnosis of complicated pulmonary unilocular cystic hydatidosis (CPUCH). STUDY DESIGN Sputum, bronchial washing and bronchial brushing specimens obtained from 131 patients with a presumptive diagnosis of CPUCH were reviewed. RESULTS CPUCH was histopathologically proven in 111 of 131 patients. Scolices were found in 11 patients in Papanicolaou-EA65 (PAP-EA65)-stained slides. Special stains and dark field microscopy (DFM) did not make any additional contribution to specifying the nature of the scolexlike objects. Hooklets were found in 26 patients in PAP-EA65-stained slides. Masson's trichrome stain and DFM revealed hooklets in 37 and 50 cases, respectively. Laminated membrane fragments were found in 14 patients in PAP-EA65-stained slides. Gomori's methenamine silver stain and DFM demonstrated laminated membrane fragments in 25 and 33 cases, respectively. Secondary cytologic criteria, such as multinucleated giant cells, degenerated squamous cells, dyskaryotic squamous cells, excessive amounts of eosinophils, plasma cells, lymphocytes, histiocytes, necrotic debris, fibrinoid material and erythrocytes, were considered to be suggestive of hydatid disease when there are more than three such factors in patients with a presumptive diagnosis of CPUCH. CONCLUSION Though DFM examination is superior to cytochemical stains used in this study, both cytochemical stains and DFM are useful in increasing the sensitivity of cytologic detection of true hydatid elements, especially hooklets and laminated membrane fragments. They should be used as auxiliary techniques. Secondary cytologic criteria are suggestive of the diagnosis of CPUCH, and special care should be taken when there are more than three such factors in cytologic specimens.
