Reliability and validity of the Turkish version of the Prosthesis Embodiment Scale for Lower Limb Amputees.

BACKGROUND: Prosthetic embodiment is the perception of the prosthesis as a part of the body, and it is important for acceptance and adequate and effective use of the prosthesis. OBJECTIVE: The aim of this study was to investigate the validity and reliability of the Turkish version of the Prosthesis Embodiment Scale for Lower Limb Amputees. METHODS: This cross-sectional study included a total of 88 lower limb amputees. Internal consistency was evaluated using Cronbach α coefficient. The test-retest reliability of the scale, which was reapplied after 7-10 d, was evaluated using intraclass correlation coefficient. Principal component analysis with Varimax rotation was used to analyze the factor structure. Spearman correlation coefficient with Trinity Amputation and Prosthesis Experience Scale subscales was calculated for concurrent validity. RESULTS: The mean age of the participants was 45.13 ± 15.05 years, and 76.1% were male. Internal consistency (Cronbach α = 0.905) and test-retest reliability (intraclass correlation coefficient = 0.822) were high. 76.1% of the total variance could be explained by the 3 dimensions. Significant correlation was found with the Trinity Amputation and Prosthesis Experience Scale subscales (r = 0.542 for psychosocial adjustment subscale, r = -0.452 for activity restriction subscale, r = 0.490 for prosthesis satisfaction subscale, p < 0.001). CONCLUSIONS: The results of this study showed that the Turkish version of the Prosthesis Embodiment Scale for Lower Limb Amputees is a valid and reliable tool that can be used to evaluate prosthetic rehabilitation outcomes.

A systematic review and network meta-analysis on comparative efficacy, acceptability, and safety of treatments in acute bipolar mania in youths.

BACKGROUND: The evidence of treatment options' efficacy on acute bipolar manic episodes is relatively less in youths than adults. We aimed to compare and rank the drug's efficacy, acceptability, tolerability, and safety for acute mania in children and adolescents. METHOD: We systematically reviewed the double-blinded, randomized controlled trials (RCTs) comparing drugs or placebo for acute manic episodes of bipolar disorder in children and adolescents using PRISMA guidelines. We searched PubMed/MEDLINE, EMBASE, Web of Science, EBSCO, Scopus, the Cochrane Central Register of Controlled Trials, and https://clinicaltrials.gov from inception until November 20, 2022. Response to treatment was the primary outcome, and random-effects network meta-analyses were conducted (PROSPERO 2022: CRD42022367455). RESULTS: Of 10,134 citations, we included 15 RCTs, including 2372 patients (47 % female), 15 psychotropic drugs, and the placebo. Risperidone 0.5-2.5 mg/day, aripiprazole 30 mg/day olanzapine, quetiapine 400 mg/day, quetiapine 600 mg/day, asenapine 5 mg/day, asenapine 10 mg, ziprasidone, and aripiprazole 10 mg were found to be effective (in comparison with placebo) in children and adolescents, respectively (τ2 = 0.0072, I2 = 10.2 %). The tolerability of aripiprazole 30 mg/day was lower than risperidone 0.5-2.5 mg/day and olanzapine. Oxcarbazepine had the highest discontinuation due to the adverse effects risk ratio. LIMITATIONS: Efficacy ranking of the treatments could be performed by evaluating relatively few RCT results, and only monotherapies were considered. CONCLUSIONS: Efficacy, acceptability, tolerability, and safety are changing with the doses of antipsychotics for children and adolescents with acute bipolar manic episodes. Drug selection and optimum dosage should be carefully adjusted in children and adolescents.

Ocular pharmacokinetics and toxicity of nanoparticular acetazolamide: In vivo distribution and safety of PHBV-ACZ nanoparticle.

Diabetic macular edema (DME) is defined as fluid accumulation in the macular region, between the retinal layers, due to many diseases, especially diabetes. DME is one of the major complications of diabetic retinopathy (DRP). Carbonic anhydrase inhibitors (CAI) are a pharmaceutical agent used in different fields, especially glaucoma treatment. Acetazolamide (ACZ), which is a CAI, is an active substance that has been used off-label for many years in the treatment of macular edema due to diabetes and many other diseases. The low solubility and bioavailability of ACZ limit its use in the treatment of DME. In this study, a nanoparticulate formulation was developed that would increase the solubility and bioavailability of ACZ and allow it to be administered intravitreally. ACZ was loaded on poly(3-hydroxybutyrate-co-3-Hydroxyvalerate) (PHBV) nanoparticles and the loading efficiency was 71.58 ± 1.22%. Toxicity of nanoparticles after intravitreal application was evaluated with anterior segment and posterior segment examination findings, intraocular pressure (IOP) measurements and electrophysiological tests. At the end of the 3-month follow-up, electroretinography (ERG) measurements demonstrated that ACZ loaded PHBV (PHBV-ACZ) nanoparticles did not cause loss of function in retinal cells. On histological examination, rare degenerative changes were observed in several cell groups. In addition, pharmacokinetic studies were performed to determine the tissue distribution of ACZ at various periods. ACZ was identified in vitreous humor and retina at the highest concentration. Based on our results, the prepared nanoparticle formulation can release long-term CAI for DRP therapy and accordingly can reduce the need for monthly intravitreal injections.

Determination of the factors contributing to depression and anxiety in advanced stage lung cancer patients.

Background: The diagnosis of cancer and initiation of treatment disrupt physical, emotional, and socio-economical stability of the patients by reducing the quality of lives and ultimately leading to depression and anxiety. We aimed to observe the indicators for anxiety and depression among lung cancer (LC) patients by comparing with other cancer (OC) patients. Methods: This study has been conducted between 2017 and 2019. Questionnaires were provided for both LC and OC patients. Results: Two hundred and thirty patients with the ages varied between 18 and 86 (median: 64.0) were included in the study. A total of 115 patients (case group) were diagnosed as LC, and the remaining were with OC diagnosis (control). No difference was determined between the groups in means of median anxiety and depression scores. Patients who required assistance in hospital procedures, daily life activities, and self-care had higher depression and anxiety scores (p < 0.05) compared to those did not require assistance. Anxiety and depression scores in OC groups showed a remarkable difference according to performance status (p < 0.001). The depression score of the patients who stated that they did not know their social rights was remarkably higher than those of the patients who stated that they know their social rights. We found no relationship between depression and anxiety scores because of disease caused income loss and expense increase. Conclusion: For LC patients, declaration of requirement for assistance and supportive care in daily life can be an important indication for anxiety and depression. Lung cancer patients, especially those informed by health care professionals and provided psychosocial support following the information, require a patient-specific professional management approach.

Postmortem Interval Estimation With Corneal Endothelial Cell Density.

OBJECTIVES: In the neonatal period, healthy people have the highest corneal endothelial cell density (CECD) (5000-7000 cells/mm2). Corneal endothelial cell density declines with age in adults (2500-3000 cells/mm2) and continues to decline in the postmortem period. We measured CECD in cases with different postmortem interval (PMI) and investigated its association with PMI. METHODS: A total of 555 corneas harvested from 285 cases with a known time of death were examined using a specular microscope. RESULTS: Postmortem corneal removal time ranged between 10 and 1395 minutes. The CECD averages were 2653 for right cornea and 2678 cells/mm2 for left cornea. An inverse but nonlinear relationship was found between age and CECD. In both men and women, there was an inverse and weak correlation between age and CECD (ρ = -0.282; P < 0.001; ρ = -0.264; P < 0.001, respectively). There was no significant relationship between postmortem corneal removal time and CECD (ρ = 0.049; P = 0.421; ρ = 0.011; P = 0.855 for right and left corneas, respectively). The highest decline in time dependent CECD was detected between the 480th and 540th minutes at -7.2%. CONCLUSIONS: We found no significant decrease in CECD numbers according to PMI or cause of death. Experimental studies on cases with known and standardized antemortem CECD values will provide essential results in estimating PMI.

Complementary and Alternative Medicine Attitudes of Gynecologic Patients: Experience in a Tertiary Clinic.

OBJECTIVE: To evaluate the knowledge, attitudes, and behaviors regarding complementary and alternative medicine methods of patients who were admitted to gynecology outpatient clinics. METHODS: In the present survey, a questionnaire on complementary and alternative medicine practices was applied on 1,000 women (ages between 18 and 83 years old) who were admitted to the gynecology outpatient clinic of a tertiary maternity hospital. Demographic features and knowledge, attitudes, and behaviors about these methods were inquired in face-to-face interviews. RESULTS: While 80.7% of the total participants thought that complementary and alternative medicine was beneficial, only 37.5% of them had used these methods previously. The rate of prior knowledge on this subject was of 59.7% and the source of information was physicians for 8.5% of the patients. However, 72.4% of all participants wanted to obtain information on these methods and 93.7% wanted to be informed by physicians. In the decision tree model, having knowledge about complementary and alternative medicine was the most effective factor determining its use (p < 0.001). Phytotherapy was found to be the most used method, with 91.4%. The most preferred plant was onion (18.9%), and the most common reasons for herbal use were stress (15.4%) and fatigue (15.2%). CONCLUSION: More than one-third of the patients who applied to the gynecology outpatient clinics used one of the complementary and alternative medicine methods at least once. As gynecologists and obstetricians, we need to be more knowledgeable about these methods to provide correct guidance to our patients for accessing accurate and effective information.

The Effects of Water Immersion during First Stage of Labor on Postpartum Systemic Inflammatory Response.

OBJECTIVE: The systemic inflammatory response is a cascade of physiologic reactions that arise in response to trauma, infection, burn, or any kind of injury. This study aimed to determine the effects of water immersion during the first stage of labor on the systemic inflammatory indices in the postpartum period. MATERIALS AND METHODS: In this retrospective study, 125 healthy multiparous women with uncomplicated pregnancies between 37 and 41 weeks of gestation who elected for immersion in water during the first stage of labor were compared with multiparous uncomplicated term women who had conventional vaginal births on land (n=125). Age, parity, body mass index (BMI), gestational age, duration of labor, birth weight, Apgar scores, neonatal intensive care unit admissions, and ante- and postpartum whole blood parameters were noted. Antepartum and postpartum neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) were calculated for all patients as systemic inflammatory indices. RESULTS: Demographic characteristics and birth outcomes of both groups were similar except BMI, which was statistically significantly higher in the water immersion group. There were no statistical differences in antepartum NLR, MLR, PLR, and MPV between the 2 groups. However, postpartum NLR, MLR, PLR, and MPV were statistically significantly lower in the water immersion group compared to the controls. CONCLUSION: Water immersion during the first stage of labor might decrease systemic inflammatory indices in the early postpartum period.

Intramyocardial Transplantation of Umbilical Cord Mesenchymal Stromal Cells in Chronic Ischemic Cardiomyopathy: A Controlled, Randomized Clinical Trial (HUC-HEART Trial).

BACKGROUND AND OBJECTIVES: The HUC-HEART Trial (ClinicalTrials.gov Identifier: NCT02323477) was a controlled, prospective, phase I/II, multicenter, single-blind, three-arm randomized study of intramyocardial delivery of human umbilical cord-derived mesenchymal stromal cells (HUC-MSCs) combined with coronary artery bypass-grafting (CABG) in patients with chronic ischemic cardiomyopathy (CIC). The trial aimed to assess (i) the safety and the efficacy of cell transplantation during one-year follow-up, (ii) to compare the efficacy of HUC-MSCs with autologous bone-marrow- derived mononuclear cells (BM-MNCs) in the same clinical settings. METHODS AND RESULTS: Fifty-four patients who were randomized to receive HUC-MSCs (23×106) (n=26) or BM-MNCs (70×107) (n=12) in combination with CABG surgery. The control patients (n=16) received no cells/vehicles but CABG intervention. All patients were screened at baseline and 1, 3, 6, 12 months after transplantation. Forty-six (85%) patients completed 12 months follow-up. No short/mid-term adverse events were encountered. Decline in NT-proBNP (baseline∼ 6 months) in both cell-treated groups; an increase in left ventricular ejection fraction (LVEF) (5.4%) and stroke volume (19.7%) were noted (baseline∼6 or 12 months) only in the HUC-MSC group. Decreases were also detected in necrotic myocardium as 2.3% in the control, 4.5% in BM-MNC, and 7.7% in the HUC-MSC groups. The 6-min walking test revealed an increase in the control (14.4%) and HUC-MSC (23.1%) groups. CONCLUSIONS: Significant findings directly related to the intramyocardial delivery of HUC-MSCs justified their efficacy in CIC. Stricter patient selection criteria with precisely aligned cell dose and delivery intervals, rigorous follow-up by detailed diagnostic approaches would further help to clarify the responsiveness to the therapy.

Vaccination rates for Syrian population under temporary protection in Turkey.

OBJECTIVES: The aim of this study was to gather information on demographic and health indicators, primarily vaccination status, of Syrians under temporary protection in five provinces of Turkey and to develop infrastructure for vaccination planning. METHODS: The population under study consists of 89,986 Syrian children, 0-4 years of age, residing in Ankara, Mersin, Gaziantep, Izmir, and Bursa. Initially, we planned to evaluate 2,339 children, although a total of 2,827 children were evaluated by the end of the study. RESULTS: Of these children, 74% were born in Turkey, while 20% were born in Syria. In addition, 22.4% (n = 634) of the children were never vaccinated, and of these, 67.0% (n = 425) were born in Turkey. In other words, one in five Syrian children born in Turkey (20.3%) had never been vaccinated. Of the Syrian children under temporary protection, the missing vaccinations were as follows: hepatitis B (54.7%); Bacillus Calmette-Guérin (62.5%); five-component combined vaccine (64.6%); conjugated pneumococcal vaccine (58.0%); oral polio vaccine (70.8%); measles, mumps, and rubella (76.6%); varicella (66.8%); and hepatitis A vaccine (76.0%). CONCLUSION: It is important to increase the immunization rates of Syrian children under temporary protection and establish regular vaccination procedures.

Insufficiency of positive airway pressure treatment on increased mean platelet volume: a prospective controlled study in patients with obstructive sleep apnea syndrome.

BACKGROUND: To analyze the association between obstructive sleep apnea syndrome (OSAS) and some hematological variables such as mean platelet volume (MPV), platelet distribution width (PDW), and the impact of positive airway pressure (PAP) treatment on these parameters. METHODS: The participants of the present prospective study consist of 36 OSAS patients diagnosed with polysomnography and recommended PAP treatment and 30 healthy members as the control group. Complete blood analyses were conducted to the patient group twice; before the initiation of the PAP treatment and 1 month after regular PAP use. The control group was administered a complete blood analyses only once. Patient and control group were compared in terms of various parameters such as MPV, PDW, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), white blood cell (WBC) values, and platelet counts. RESULTS: MPV value of the patient group was before and after PAP treatment significantly higher than the control group (respectively; Z = 2.246; p = 0.025, and Z = 2.033; p = 0.042). However, there were no statistically significant differences in the values before and after PAP treatment in the patient group (Z = 0.727; p = 0.467). In terms of platelet numbers and PDW values, no significant differences were determined (p > 0.05). CONCLUSION: MPV value was significantly elevated in OSAS patients. However, the 1 month of PAP treatment was insufficient in decreasing elevated MPV values.

Lipid accumulation product is a predictor of nonalcoholic fatty liver disease in childhood obesity.

BACKGROUND: Lipid accumulation product (LAP) is associated with the presence and severity of nonalcoholic fatty liver disease (NAFLD) in adults. PURPOSE: Here we evaluated the ability of LAP to predict NAFLD in obese children. METHODS: Eighty obese children (38 girls; age 6-18 years) were included. Anthropometric measurements and biochemical values were obtained from the patients' medical records. LAP was calculated as [waist circumference (WC) (cm) - 58]×triglycerides (mmol/L) in girls; [WC (cm) - 65]×triglycerides (mmol/ L) in boys. The minLAP and adjLAP were described (3% and 50% of WC values, respectively) and the total/high-density lipoprotein cholesterol index (TC/HDL-C) was calculated. NAFLD was observed on ultrasound, and patients were divided into 3 groups by steatosis grade (normal, grade 0; mild, grade 1; moderate-severe, grade 2-3). The area under the curve (AUC) and appropriate index cutoff points were calculated by receiver operator characteristic analysis. RESULTS: LAP was positively correlated with puberty stage (rho=0.409; P<0.001), fasting insulin (rho= 0.507; P<0.001), homeostasis model assessment of insulin resistance (rho=0.470; P<0.001), uric acid (rho=0.522; P<0.001), and TC/HDL-C (rho=0.494; P<0.001) and negatively correlated with HDL-C (rho=-3.833; P<0.001). LAP values could be used to diagnose hepatosteatosis (AUC=0.698; P=0.002). The LAP, adjLAP, and minLAP cutoff values were 42.7 (P=0.002), 40.05 (P=0.003), and 53.47 (P= 0.08), respectively. For LAP, the differences between the normal and mild groups (P=0.035) and the normal and moderate-severe groups were statistically significant (P=0.037), whereas the difference between the mild and moderate-severe groups was not (P>0.005). There was a statistically significant difference between the normal and mild groups for adjLAP (P=0.043) but not between the other groups (P>0.005). There was no significant intergroup difference in minLAP (P>0.005). CONCLUSION: LAP is a powerful and easy tool to predict NAFLD in childhood. If LAP is ≥42.7, NAFLD should be suspected. This is the first study to assess LAP diagnostic accuracy for childhood obesity.

Expression of Immunomodulatory Molecules PD-1, PD-L1, and PD-L2, and their Relationship With Clinicopathologic Characteristics in Endometrial Cancer.

Chemotherapeutic agents are not very effective in treating advanced endometrial cancers (ECs). Recent studies have demonstrated the immune evasion mechanism of tumors and possible remedies. Programmed cell death protein 1 (PD-1), programmed death ligand 1 (PD-L1), and programmed death ligand 2 (PD-L2) are immunomodulator molecules that have been the focus of research in lung cancer, melanoma, and renal cell cancer. However, there are few studies concerning EC. This retrospective study aimed to determine PD-1, PD-L1, and PD-L2 expression immunohistochemically in EC, and to study their correlation with clinicopathologic tumor characteristics. This study comprised 127 patients with EC. Anti PD-1, PD-L1, and PD-L2 antibodies were examined immunohistochemically on sections obtained from tissue microarray paraffin blocks. No staining with PD-1 in tumor cells was seen; however, we found positive staining in tumor cells at 36.2% with PD-L1 and 64.4% with PD-L2, and at 61.6% with PD-1, 36.2% with PD-L1, and 93.2% with PD-L2 in immune cells. When comparing staining and clinicopathologic findings, most of the PD-L1 negative tumors (both in tumor and immune cells) were FIGO Stage I, which was significantly higher than stage II-III-IV tumors (P<0.05). There was a statistically significant association between the FIGO grade and the PD-L1 score in immune cells (P=0.009), and between staining of PD-1, PD-L1, and PD-L2 and age (P=0.004, 0.013, and 0.043, respectively). Interaction between PD-1, PD-L1, and PD-L2 may be a potential target for immunotherapy in elderly and advanced stage EC patients.

Vitamin D receptor gene TaqI single nucleotide polymorphism is not associated with lead levels in maternal and umbilical cord blood.

PURPOSE: We aimed to investigate the association of vitamin D receptor (VDR) gene TaqI single nucleotide polymorphism (SNPs) with serum lead (Pb) levels in maternal and umbilical cord blood. MATERIALS AND METHODS: Eighty-one patients who lived in Konya, Turkey for the last 3 years and had delivery at Baskent University Konya Hospital in 2016 were included in this study. Venous blood samples were drawn from each volunteer immediately before giving birth to determine the maternal Pb levels and VDR SNPs. Additionally, umbilical cord blood samples were collected from the umbilical vein into tube with EDTA as an anticoagulant immediately after birth to determine Pb levels of the fetus. RESULTS: The median level of Pb in the maternal blood was 29.00 (Interquartile Range (IQR) = 16.35) µg/L and the median Pb level in the cord blood was 22.50 (IQR = 9.75) µg/L. Blood Pb level of women living in the urban area was significantly higher than in those living in the rural area (Z = 2.118; p = .034). There was a very strong positive correlation between the Pb levels in the maternal blood and in the umbilical cord blood (ρ = 0.825, p < .001, respectively). Regarding VDR SNPs, "TT", "TC", and "CC" VDR TaqI genotypes were observed in 28 (34.6%), 45 (55.5%), and eight samples (9.9%), respectively. Pb levels in maternal and cord blood were higher in women with the "CC" VDR TaqI genotype; however, there was no statistically significant difference (p > .05). CONCLUSIONS: Although women with the "CC" VDR TaqI genotype had higher maternal and cord blood Pb levels, this was statistically insignificant and therefore, VDR TaqI SNPs did not significantly affect maternal and umbilical cord blood Pb levels.

Incidental findings on cone-beam computed tomographic images: paranasal sinus findings and nasal septum variations.

OBJECTIVE: CBCT applications have received widespread acceptance in dentistry. CBCT scans provide three-dimensional information on anatomic structures and characteristics of pathologies, rather than the two-dimensional information obtained with the conventional techniques. The purpose of this study was to evaluate incidental findings in out-of-interest areas on CBCT images and to reveal their frequency and characteristics. METHODS: A total of 691 CBCT scans from 691 patients were assessed. Demographic data, CBCT indications, and incidental findings outside the primary area of interest, such as anatomical variations and pathologies, were noted. The incidental findings were categorized and analyzed using descriptive statistics. RESULTS: In total, 1109 incidental findings in paranasal sinuses were noted on 548 of the 691 CBCT scans. The highest rate of incidental findings was maxillary sinus findings, followed by concha bullosa and septum deviation. The most frequently observed pathology was mucosal thickening, followed by polypoid mucosal thickening in the maxillary sinus. CONCLUSIONS: While most incidental findings require no treatment, some conditions will necessitate modification of the treatment plan. Therefore, dental practitioners should be aware of incidental findings and anatomical variations. Correct identification of these findings will reduce unnecessary further diagnostic assessments and allow selection of more appropriate treatment plans.

Evaluation of the Prognostic Importance of c-Myc and Bcl-2 Expressions and the Presence of Epstein-Barr Virus in Classical Hodgkin Lymphoma.

OBJECTIVE: Although classical Hodgkin lymphoma (cHL) has a relatively good prognosis, it also entails different treatment responses and involves patients who have different clinical courses. Our aim was to investigate c-Myc, Bcl-2 and EBV biomarkers in cHL and their relationship with the IPS score. MATERIAL AND METHOD: c-Myc and Bcl-2 immunohistochemical staining with EBER in situ hybridization (EBER-ISH) was applied to the paraffin sections of 94 cases diagnosed as cHL. These cases were classified into two groups as low and high clinical symptoms according to the International Prognostic Scores (IPS). RESULTS: Positive results were obtained in 83 (88.3%) cases with c-Myc and 39 (43.5%) cases with Bcl-2 while EBER-ISH was found positive in 42 (44.7%) cases. No difference was found between the groups of low/high IP scores with respect to the positive or negative results of EBER-ISH, Bcl-2 and c-Myc. When Bcl-2 and c-Myc positive cases were grouped together and compared to the IP scores of the remaining cHL cases, again no difference was seen. Extranodal involvement and bone marrow involvement was observed in 25 (26.5%) and 9 (9.5%) cases, respectively. Similarly, no statistically significant differences was found between these groups according to their positivity with EBER-ISH, Bcl-2 and c-Myc. CONCLUSION: We could not find any relationship between Bcl-2, c-Myc and EBER-ISH positivity and the low/high IPS groups in cHL. New studies with larger series are needed in which more precise cut-off values are used and clinically and biologically heterogeneous groups of cHL patients are determined more clearly.

Evaluation of p53 and Ki67 Expression Profiles in Basal Cell Carcinomas in a Usual and an Unusual Location.

OBJECTIVE: Owing to their importance in cell proliferation in cutaneous malignancies, we aimed to immunohistochemically compare the expression profiles of p53 and Ki67 in basal cell carcinoma (BCC) cases in both a usual and an unusual locations in this study. MATERIAL AND METHOD: In this study we included 12 in an unusual location of BCC cases and 21 BCC cases in a usual location. Immunohistochemical expression of p53 and Ki67 antibodies were studied in 33 paraffin-embedded tissue specimens of basal cell carcinoma. We compared the p53 and Ki67 staining scores with clinicopathologic features. RESULTS: The tumor size was found to be greater in BCC cases in an unusual location than those in a usual location. The relationship between age and tumor size was also evaluated in both groups and it was found that tumor size increased with age. A comparative study between the two groups showed no difference p53 and Ki67 expression percentages. There was a linear correlation between the Ki67 and p53 marker staining rates (ρ=0.420; p=0.015). In the samples taken from cases in a usual region, there was a linear and moderate relationship between the markers (ρ=0.513; p=0.017). Median tumor diameter results were similar to the marker staining score (p > 0.05). CONCLUSION: This is the first study comparing the expression profiles of p53 and Ki67 of BCC cases in an unusual and a usual location.

Can Cutting-Needle Biopsy Be an Alternative to Excisional Biopsy in Lymph Node Pathologies?

OBJECTIVE: We aimed to compare cutting-needle biopsy (CNB) diagnoses with excisional biopsy diagnoses of enlarging lymph nodes and to determine the diagnostic value of CNB. MATERIAL AND METHOD: Out of the 291 cases that underwent CNB from lymph nodes between 2010 and 2016, 60 were included in the study in which pathological lymph nodes were excised after CNB. Demographic information, pathology and imaging reports, the diameters of the lymph nodes and the length of the CNBs of these cases were obtained from the hospital registry system. Diagnoses of the CNBs and excisional biopsies were then compared. RESULTS: According to the excisional biopsy diagnosis, 7 of the 60 cases (11.7%) were benign and 53 of them (88.3%) were malignant. 28 (53%) of the malignant cases were diagnosed as Hodgkin's lymphoma while the others (47%) got a non-Hodgkin's lymphoma diagnosis. In the 8 non-diagnostic CNBs, 3(37%) of them were found to be benign/reactive, while 5 (63%) were diagnosed as malign lymphoma in excisional biopsy. Similarly, 7(64%) of the 11 cases diagnosed as benign/reactive in CNB, were found to be malignant with excisional biopsy. When CNB and excisional biopsy were compared, sensitivity and specificity were 90% and 100%; positive predictive value (PPV) and negative predictive value (NPV) were 100% and 0%, respectively, and the diagnostic accuracy rate (DV) was 86.5%. The mean diameter of the benign lymph nodes was 26.1 mm and the mean diameter of the malignant ones was 35.6 mm. There was no significant difference between malignant and benign lymph node size (p > 0.05). There was also no statistically significant difference between CNB length and correct diagnosis (p=0.233). CONCLUSION: CNB is a non-invasive procedure. It is an alternative to excisional biopsy because of its low morbidity and low cost. However, the sensitivity of CNB is lower than its specificity, and we recommend the surgical excision of lymph nodes with a clinically strong neoplasm suspicion because of the presence of false negatives in 7 cases.

Plasma Amino-Terminal Propeptide of C-Type Natriuretic Peptide Concentration in Normal-Weight and Obese Children.

OBJECTIVE: In studies on the relationship between amino-terminal propeptide of C-type natriuretic peptide (NT-proCNP) concentration and height velocity in children, CNP has been implicated as an emerging new growth marker during childhood. It has been reported that besides its well-studied role in growth, plasma CNP levels are reduced in overweight and/or obese adolescents, suggesting CNP as a potential biomarker in childhood obesity. The primary goal of this study was to test this hypothesis in a Turkish population. METHODS: Consent was taken from 317 children [ages 0-18 (158 girls, 159 boys)] and their parents. All subjects were physically examined; anthropometric measurements were obtained. Body mass index was calculated. During routine blood work, 1 mL extra blood was taken. Plasma NT-proCNP concentration was measured by enzyme-linked immunosorbent assay. RESULTS: Results confirmed the previously described relationship between plasma NT-proCNP concentration and growth velocity. Plasma NT-proCNP concentration showed a negative correlation with age, weight, and height in children. Gender was not a factor that alters the age-dependent plasma NT-proCNP concentration until puberty. CONCLUSION: Unlike previous reports, plasma NT-proCNP concentration of overweight/obese children was not significantly lower than that of children with normal weight in age groups analyzed in a Turkish population. Thus, it is too early to conclude that CNP is a potential biomarker in childhood obesity. Further studies are necessary to address this question.

The weeks and the cumulative doses of the first adverse events related to oral isotretinoin in acne patients: analysis of 300 patients.

BACKGROUND: The purpose of our study is to find out in which weeks and in which cumulative doses the side effects emerge and to study whether or not there is a significant variance between the observed period and doses of the emergent side effects of the patients taking the daily doses of below and above 0.5 mg/kg. METHODS: Patients were started treatment with doses of 0.25-1 mg/kg isotretinoin, and a form was given to the patients to mark which probable side effects occurred in which weeks and called for weekly follow-up for the first 2 months. RESULTS: The median of the complaints of emerged side effects such as chellitis, dry face and facial erythema, photobia and nyctalopia was in less than 4 weeks. When the doses taken below and above 0.5 mg/kg are compared, the side effects observed to have differences between both the week they occurred and the cumulative doses are xerosis, dry face, exacerbation of acnes, nervousness, and somnolence. CONCLUSIONS: We believe that knowing which weeks the side effects are observed first, warning about the side effects that may especially occur in the first 4 weeks, and ensuring some measures are taken before the side effects are observed will increase the success of patient compatibility and management of side effects.
