Abstract
BACKGROUND Telogen effluvium (TE) is a common form of non-scarring alopecia, characterized by excessive shedding of telogen club hairs. OBJECTIVES The aim of the present study was to investigate patient characteristics, laboratory parameters, and treatment strategies in TE. METHODS Electronic records of 3028 patients were retrospectively analyzed. Demographic and clinical data, as well as serum parameters screening for iron, vitamin B12, vitamin D, folate and zinc deficiencies, thyroid function, and ANA titers, were evaluated. RESULTS In the study group, the most frequently performed test type was serum ferritin level (82.3%), followed by complete blood count (81%), both of which revealed that 6.2% of the patients had iron deficiency anemia. 4.6% of the patients had thyroid dysfunction. In screened patients, vitamin and mineral deficiencies were as follows: vitamin D (72.2%), vitamin B12 (30.7%), folate (4.4%), and zinc (2.1%). Women were more likely to be prescribed vitamin D replacement therapy. Iron replacement was the most frequently ordered treatment, comprising 37.5% of total prescriptions. CONCLUSION To the best of our knowledge, this is the most comprehensive retrospective study having the largest number of patients with TE. Our results will not only help to augment knowledge about TE, but also provide a diagnostic algorithm for the laboratory and clinical workup of patients with TE.

Abstract
Panitumumab is a recombinant, fully humanized IgG2 monoclonal antibody targeting the epidermal growth factor receptor (EGFR). Panitumumab is indicated for patients with metastatic colorectal cancer with progressive refractory disease. Targeted therapies are well known to be well tolerated; however, they may induce toxicities that are distinct from those of classical chemotherapeutic agents. For instance, EGFR inhibitors (EGFRIs) are associated with some specific dermatological adverse effects, one of which is nail toxicity. Since panitumumab is fully humanized, unlike most of the other EGFRIs, it has been reported to have reduced incidence of adverse reactions. Nail-related adverse effects are frequently observed with EGFRIs. A literature search has yielded a list of reviews describing panitumumab-induced nail toxicity. However, as far as we know, there is no case report detailing this adverse effect of panitumumab. Here, we present a case of panitumumab-induced paronychia in a 60-year-old woman with metastatic colon cancer. With this case report, we would like to review the literature and discuss the possible underlying mechanisms of this condition.

Abstract
AIM In order to determine the possible effects of diabetes, we aimed to investigate the expression of extracellular matrix proteins in the theca and granulosa layers in different follicular stages. METHODS Thirty-two adult Wistar albino male rats were divided into 4 groups as control and sampled groups. Four, eight and twelve weeks after inducing diabetes with an intraperitoneal injection of streptozotocin (40 mg/kg), the expressions of laminin, type IV collagen and α3β1 integrin in ovarian tissues were evaluated by immunohistochemical method. RESULTS In our study, in the first month of diabetes, a significant increase was observed in laminin, type IV collagen and α3β1 integrin expressions in all follicle types compared to the control group in both the theca and granulosa layers. Laminin and type IV collagen immunoreactivity tended to increase in D2 and D3 groups also. Integrin expression did not change in the newly formed follicles in the D2 and D3 groups, however, it tended to change and increase in the developing follicles. CONCLUSIONS The changes in the expression of laminin, type IV collagen and α3β1 integrin, which are the extracellular matrix proteins in the follicle, along with diabetes, show that diabetes plays a role in the regulation of follicular development (Tab. 4, Fig. 36, Ref. 29).

Abstract
Background Internalized stigma, adoption of negative attitudes and stereotypes of the society regarding persons' illness, has not been studied previously in pediatric psoriasis patients. Objective We aimed to investigate the internalized stigma in pediatric psoriasis patients and to determine differences according to factors affecting internalized stigma compared to adult psoriasis patients. Methods This multicenter, cross-sectional, comparative study included 125 pediatric (55 female, 70 male; mean age±standard deviation [SD], 14.59±2.87 years) and 1,235 adult psoriasis patients (577 female, 658 male; mean age±SD, 43.3±13.7 years). Psoriasis Internalized Stigma Scale (PISS), Dermatology Life Quality Index (DLQI), Perceived Health Status (PHS), and the General Health Questionnaire (GHQ)-12 were the scales used in the study. Results The mean PISS was 58.48±14.9 in pediatric group. When PISS subscales of groups were compared, the pediatric group had significantly higher stigma resistance (p=0.01) whereas adult group had higher scores of alienation (p=0.01) and stereotype endorsement (p=0.04). There was a strong correlation between mean values of PISS and DLQI (r=0.423, p=0.001). High internalized stigma scores had no relation to either the severity or localization of disease in pediatric group. However, poor PHS (p=0.007) and low-income levels (p=0.03) in both groups, and body mass index (r=0.181, p=0.04) in the pediatric group were related to high PISS scores. Conclusion Internalized stigma in pediatric patients is as high as adults and is related to poor quality of life, general health, and psychological illnesses. Unlike adults, internalized stigma was mainly determined by psoriasis per se, rather than disease severity or involvement of visible body parts, genitalia or folds.

Abstract
AIM Cornus mas L is commonly used due to its anti-inflammatory, anti-carcinogenic and anti-oxidant properties. In the study, the effects of C. mas L extract on a solid tumor were examined in the Ehrlich solid tumor model developed in Balb/C type mice. METHODS Ehrlich acid tumor (EAT) cells (1x106 EAT cell) from the stock animal were injected subcutaneously (s.c.) through the nape of the mice. Treatment groups of solid tumor-induced animals received 100 mg/kg and 200 mg/kg of C. mas L extract intraperitoneally (i.p.) for 14 days. RESULTS Tumor volumes and animal weights were found to be statistically significant compared to the control group (p < 0.05). AgNOR staining was performed in tumor tissues. Statistically significant differences were observed between the groups in terms of TAA/NA ratio (p < 0.05). Immunohistochemical and biochemical parameters were also evaluated. An estimation of tumor proliferation of the lung, liver, brain, kidney, testis and tumor antioxidant parameters viz. lipid peroxidation, reduced glutathione (GSH), glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) was made. CONCLUSIONS Our study showed that the anti-tumor effect of C. mas L in assisted tumor development with EAT cells, was mediated by the enhancement of oxidative stress with multiple mechanisms (Tab. 6, Fig. 12, Ref. 38).

Abstract
Background Palmoplantar pustulosis is a chronic and relapsing disease of the palms and soles, which is characterized by scattered clusters of pinhead-sized, sterile pustules. Objective The aim of the present study was to determine demographic features, co-morbidities, and relation of palmoplantar pustulosis with psoriasis. Methods A total of 48 patients (M/F: 15/33) were enrolled in the present study. A detailed history regarding age of onset, palmoplantar pustulosis duration, number of recurrences, personal and family history of psoriasis, accompanying arthritis, sternoclavicular tenderness, dental fillings, smoking status, and autoimmune disease was obtained; thorough dermatological examination was carried out. Patch testing results and laboratory investigations for thyroid autoimmunity were recorded. Results Thirty-five of 48 patients (72.9%) were current smokers. Twenty of the 48 patients (41.7%) had dental fillings. There was not any significant correlation between palmoplantar pustulosis duration and dental filling duration (p = 0.170). Psoriasis was not detected in any patients either in history or in dermatological examination. Nail involvement and joint complaints were observed in seven of 48 patients (14%) and in nine of 48 patients (18%), respectively. Autoimmune thyroiditis was observed in four of 48 patients (12%). Patients with patch testing positivity (12.5% of patients, M/F: 1/5) had no considerable association for history of external contact with these materials. Study limitations Retrospective analysis. Conclusion Palmoplantar pustulosis appears to be a distinct entity from psoriasis. Routine thyroid functions test could be analyzed, but patch testing is not required in patients with palmoplantar pustulosis. Also, patients with palmoplantar pustulosis must be evaluated for musculoskeletal symptoms and signs.

Abstract
BACKGROUND Rosacea may result in emotional distress and anxiety. However, data on the presence of generalized anxiety disorder in rosacea patients are scarce. OBJECTIVE The aim of the study was to detect the frequency and level of anxiety and depression in patients with rosacea. METHODS A total of 194 consecutive rosacea patients and 194 age- and sex-matched controls were enrolled. Severity of rosacea was assessed in patients according to the criteria of the National Rosacea Society Ethics Committee. Both patients and controls were evaluated by the Generalized Anxiety Disorder 7-item scale, and severity was measured by the Generalized Anxiety Disorder-Adult. RESULTS Individuals who were diagnosed with an anxiety and/or depressive disorder were more common in patient group (24.7% vs. 7.2%, p<0,01). Female patients were particularly at risk for having generalized anxiety disorder (OR=2.8; 95% CI 1.15-7.37; p=0.02). STUDY LIMITATIONS Single center study and limited sample size. CONCLUSIONS Rosacea patients show greater risk of having anxiety disorders, including generalized anxiety disorder. Female patients, those with lower educational levels, those with phymatous subtype, untreated patients, and patients with prior psychiatric morbidity may be at particular risk for anxiety. It is essential to consider the psychological characteristics of patients to improve their well-being.

Abstract
Ibrutinib is an oral covalent inhibitor of the Bruton's tyrosine kinase pathway and is approved for the treatment of B-cell malignancies including chronic lymphocytic leukaemia, mantle cell lymphoma, and Waldenström's macroglobulinaemia. It is generally a drug of choice for high-risk patients with indolent lymphomas. The safety profile of ibrutinib appears to be tolerable, with well-known side effects such as infections and haematologic complications. Additionally, dermatological adverse reactions with ibrutinib therapy have been reported to encompass maculopapular rash and hair/nail abnormalities. Here, we present a case of ibrutinib-induced paronychia and periungual granulation in a 40-year-old woman. To the best of our knowledge, this is the third description of ibrutinib-induced paronychia and periungual granulation.

Abstract
BACKGROUND Management of chronic urticaria (CU) is often difficult with oral antihistamines (OAs) despite long-term use. OBJECTIVE The aim of this study was to determine the extent of medication compliance (MC) and to assess the factors affecting the MC of patients with CU toward OA therapy. METHODS A 43-item questionnaire was administered to 201 adult patients. A compliance score (CS) of 6 points was chosen as a cutoff point. A CS of 0-6 corresponds to poor compliance and score of 6-9, to good compliance. Subsequently, associations with compliant and poorly compliant groups were made by univariate and multivariate analyses. RESULTS The median age and disease duration of all patients were 47 years (range: 18-88) and 15 months (range: 1.5-480), respectively. Overall, the rate of compliant and poorly compliant patients was 53.2% and 46.8%, respectively. Educational level and job status were significantly associated with MC. To have graduated from university and high school increased MC by 9.1-fold (p = .002, 95% confidence interval (CI): 2.26-36.37) and 3.6-fold (p = .019, 95% CI: 1.26-13.47), respectively, compared with illiterates. Patients who had worked previously and were currently looking for work were 4.8-fold (p = .032, 95% CI: 1.14-19.97) more compliant than patients who had never worked. CONCLUSION Most patients with CU had good compliance with OAs. Educational level and job status were significant predictors of MC to OAs in CU. The impact and long-term effects of education and job status should be evaluated in different patient groups.

Abstract
BACKGROUND Over the past years, with the availability of relatively well tolerated, very effective but expensive drugs, biologics, treatment of psoriasis has dramatically shifted from inpatient modalities to outpatient ones. Relatively little is known about true life practices regarding psoriasis treatment in our country. AIMS To assess the impact of introduction of conventional drugs and biological drugs on medical resource use of psoriasis patients. STUDY DESIGN A retrospective chart review was performed. METHODS Patients with the diagnosis of psoriasis who were seen in the period between 2010 and 2015 were included in the study. Data including hospital resource use (inpatient, outpatient, day ward) and treatment modalities were collected. RESULTS The study population comprised 845 patients with 1053 different treatment modalities. There was not any significant difference between number of in-hospital days and frequency of hospitalization between biological drugs and cyclosporine. There was significant (p < .05) decline in the length of hospitalization after the year 2012 in biological treatment group. CONCLUSIONS Treatment of MSP with classical drugs requires fairly similar medical resource expenditures as biologics.

Abstract
Angina bullosa hemorrhagica (ABH) is an infrequent dermatosis characterized by acute onset of hemorrhagic bulla in the oral cavity. Clinical presentation of ABH may be quite worrisome, and clinicians often feel skeptical regarding their clinical diagnosis and lack confidence in managing this distinct entity. Indeed, ABH is a completely benign and self-limited disorder. The exact etiopathogenesis of ABH is still unknown. There have been reports in the literature addressing a central role for mechanical instability of the epithelial-connective tissue connection in the pathogenesis of ABH. Moreover, it has been claimed that long-term usage of inhaled glucocorticoids (GCs) is involved in the development of ABH, since most of the reported cases are asthmatic patients, who were treated with inhaled GCs, and GCs are well known for their degradative activities on collagen formation. Here, we describe a case with ABH, who had a drug history of inhaled GCs and nonsteroidal anti-inflammatory drugs (NSAIDs). We assume that our case not only supports the association of inhaled GCs with ABH but also suggests a possible role for NSAIDs in the pathogenesis of ABH.

Abstract
Background Venous thromboembolism (VT) increases mortality and morbidity in cancer patients. The primary aim of this study was to evaluate the effect of VT on the survival of cancer patients and its relationship with serum vascular endothelial growth factor (VEGF) and plasma factor VIII levels. Patients and methods Eighty-two patients with locally advanced or metastatic cancer were included in this study between September 2001 and March 2004, and 31 of them had VT. Fifty-one matched-paired cancer patients without VT were prospectively selected as a control group in the same period. Criteria for the selection of control group patients were having the same malignancy, stage, metastatic site, performance status and age (±5 years) as patients in the VT group. Results Plasma factor VIII and serum D-dimer levels in the VT group were significantly higher than those in the control group (p=0.030 and p=0.016, respectively). However, mean serum VEGF levels were similar in both groups (p=0.199). In the VT group, the median survival of patients who had higher serum VEGF levels (>150 pg/mL) was significantly shorter than that of patients in the same group with lower serum VEGF levels (p=0.005). The median survival of the VT group was 14 months, whereas it was 25 months in the control group (p=0.199). Conclusion There was a worse prognostic trend for cancer patients with VT. Nevertheless, the difference in survival was not statistically significant between the groups. Plasma factor VIII and serum D-dimer levels might have prognostic value in cancer patients with VT. Cancer patients with VT and higher serum VEGF levels had a significantly poorer prognosis.

Behavioural characterization of AnkyrinG deficient mice, a model for ANK3 related disorders. Behav Brain Res 2017; 328:218-226. [PMID: 28411148 DOI: 10.1016/j.bbr.2017.04.014] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2017] [Revised: 04/05/2017] [Accepted: 04/08/2017] [Indexed: 12/28/2022]
Abstract
ANK3 encodes AnkyrinG (AnkG), a member of the Ankyrin family that is expressed in several different isoforms in many tissues. A unique serine-rich domain and tail domain in the two largest isoforms of AnkG (270 and 480kDa), restrict AnkG to the axon initial segment and nodes of Ranvier of myelinated neurons. At these sites, AnkG is a master regulator, coordinating the strict clustering of components necessary for proper action potential initiation and propagation along the axon. These components include voltage-gated sodium channels, potassium channels and members of the L1 cell adhesion molecule family. Genetic variation in the ANK3 gene has been linked to a range of neuropsychiatric and neurodevelopmental disorders in human, including schizophrenia, bipolar disorder, intellectual disability and autism spectrum disorders. Here, we study the effect of reduced expression of the large isoforms of Ank3 on cognition and behaviour using a heterozygous knockout mouse model. In three independent behavioural tests, being the open field test, elevated plus maze and social interaction test, we found evidence for increased anxiety in our Ank3 mouse model. Besides, we observed specific neuroanatomical defects in heterozygous knockout mice, including a smaller cingulate cortex, granular retrosplenial cortex, primary motor cortex and fimbria of the hippocampus.

Abstract
UNLABELLED Venous thromboembolism (VTE) is one of the most common complications in cancer patients. Although factor V Leiden (FVL) is the most common genetic defect causing thrombosis, the impact of gene abnormalities on thrombotic tendency in cancer patients remains poorly explored. Tissue factor (TF) is a major physiologic initiator of blood coagulation. This is the first study regarding the association of TF gene -603A/G and +5466A>G polymorphisms with VTE in malignancy. Materials and Me-thods: The study consists of two groups: cancer patients with VTE were included as Group 1 (n = 46); Group 2 comprises 196 cancer patients without VTE. Restriction fragment length polymorphism method was used for the detection of polymorphisms of TF -603A/G in the 5՛upstream region and TF 5466A/G in intron 2. FVL, PT G20210A and MTHFR C677T polymorphisms were determined by using commercially available Light Cycler kits. The genotype and allele frequencies between the groups were compared using χ2 or Fisher exact test, if appropriate. RESULTS No differences were observed in the distribution of TF gene -603A/G genotype frequencies between the groups. Although a slightly increased incidence of +5466GA genotype was in Group 1 (17.4% vs 11.2%), it did not achieve statistical significance. The prevalence of FVL was significantly greater in Group 1 compared with Group 2 (41.3% vs 4.1%, p < 0.05). Difference in frequency of 677TT+CT (MTHFR) + 5466GG (TF) genotypes combination was found in women of two investigated Groups (p < 0.05). No differences were also in genotypes and allele frequencies of MTHFR C677T and PT G20210A between two Groups (p > 0.05). CONCLUSIONS The present study did not show significant association of TF gene -603A/G and +5466A>G polymorphisms with VTE in malignancy, however, further larger studies including different ethnic population are needed to confirm our findings.

Abstract
OBJECTIVE Many older women are hesitated to initiate discussions about urinary symptoms and their incontinence. The aim of this study is to determine the prevalence of occult urinary incontinence in outpatient older women and to evaluate its association with other geriatric conditions. PATIENTS AND METHODS 100 female patients 65 years and older were assessed at the geriatric outpatient clinic. The validated form of the Turkish version of the International Consultation on Incontinence Questionnaire-Short Form was used to evaluate urinary incontinence and quality of life. Comprehensive geriatric assessment including activities of daily living, instrumental activities of daily living, mini mental state examination and geriatrics depression scale was performed. The number of falls, comorbid conditions and number of medications were noted. The association between urinary incontinence and geriatric domains were evaluated with logistic regression analysis. RESULTS A total of 100 patients were evaluated, 64 of them included in the study. The median age of patients was 72.5. The rate of urinary incontinence was found 40.6%. The association between urinary incontinence and quality of life, performance status and comorbidity was found statistically significant with logistic regression (p = 0.033, p = 0.005, p = 0.031 respectively). Half of the patients with UI believe that it is part of normal aging and no definite treatment is available. CONCLUSIONS Occult urinary incontinence is a significant problem in older women that inversely affecting the quality of life. The study suggests that awareness and education regarding incontinence should be increased among elderly patients and screening of urinary incontinence is an important part of the geriatric assessment. The evaluation and management of functional status and comorbid conditions should be the initial step during incontinence management in elderly patients.

Abstract
AIM Identification of patient with increased risk of cardiotoxicity would allow not only prevention and early diagnosis of chemotherapy related cardiotoxicity but also administration of optimal dose and duration of chemotherapy. MATERIALS AND METHODS Fifty-two women with HER2(+) breast cancer treated with trastuzumab were included in this study. Patients were prospectively followed with routine cardiac evaluation. Before and after administration of trastuzumab blood samples for NT-proBNP were also taken. RESULTS The median age was 48.5 year (range: 26-74). Hypertension and obesity were two most common co-morbidities. The median duration application of trastuzumab was 52 weeks. During median 14.5 (3-33) months follow-up cardiac adverse events occurred in 5 (9.6%) patients and 2 out of 5 was grade III-IV heart failure. Both patients had preserved left ventricular ejection fraction and no symptom of heart failure before trastuzumab but older than 65 years old and had diabetes mellitus and obesity. High level of NT-proBNP (> 300 ng/ml) was observed in both patients and heart failure recovery was not observed. There was statistically significant difference regarding body mass index (p = 0.004) and diabetes mellitus (p = 0.002) between patients with and without cardiotoxicity. CONCLUSION Although, cardiac biomarkers still cannot replace routine cardiac monitoring, natriuretic peptides may provide additional tool for detection of patients with high risk of cardiotoxicity and early detection of cardiotoxicity.

Abstract
According to the analysis on locally advanced breast cancer (LABC) from all breast cancer cases recorded in Surveillance Epidemiology and End Results database between the years 1992-1999 in the United States, the incidence of LABC were found to be 4.6% of all female breast cancers. Clinically, when breast cancer has advanced locoregionally but has not yet spread outside of the breast and regional lymph nodes, it is considered LABC. LABC includes breast cancers that have evidence of a large mass, involve the skin of the breast or the underlying muscles of the chest wall, and cancers that have infiltrated into the local lymph nodes. The prognosis of patients with LABC is relatively poor, with 5-year survival rates less than 50%. Because the incidence of LABC is very low, there are not many studies comparing neoadjuvant chemotherapy regimens in the literature. In management of LABC, initial therapy should be systemic neoadjuvant chemotherapy, aiming pCR. Anthracycline-based chemotherapy regimens are frequently recommended as the standard primary neoadjuvant chemotherapy for the treatment of LABC. Today, the optimal duration of neoadjuvant chemotherapy is unknown. Neoadjuvant endocrine therapy is considered an option for patients with hormone receptor-positive LABC. Ongoing clinical trials are now under way to evaluate the use of novel targeted agents in the neoadjuvant treatment of LABC.

Abstract
Breast cancer is the most common female malignant disease in the western countries where a woman's lifetime risk of developing the disease is more than 10%. Nulliparity or use of hormonal replacement therapy, strong family history, or a history of therapeutic thoracic radiation are considerable high risk factors for the development of breast cancer. Nowadays more new effective therapeutic agents have been developed for the intervention of the breast cancer, but prognosis is still remained poor in the metastatic disease. For the general population, screening mammography in women older than 40-45 years has been shown to be effective in identifying early-stage breast cancer and in decreasing the mortality rate. In randomized screening mammography trials for breast cancer, it has been established that screening mammograms reduced breast cancer mortality in women older than 50 years of age by 25 to 30%. This review article summarizes the risk factors for developing breast cancer, methods for risk assessment and the accepted screening guidelines.

Abstract
PURPOSE The role of genetic factors in the development of cancer is widely accepted. Data on the role of ABO blood group and Rh factor in breast cancer is inconclusive. The aim of this study was to investigate the presence of a possible association between HER2 (+) breast cancer in Turkish women and ABO blood groups and Rh factor. METHODS In 294 female patients with HER2 (+) breast cancer, ABO blood groups and Rh factor were examined. The relationship of blood groups with age, menopausal status, and family history of cancer, estrogen receptor (ER), progesterone receptor (PR) and HER2 status of these patients was evaluated. Blood groups distribution of 22,821 healthy blood donors was also assessed and compared with the patients' blood groups distribution. RESULTS The median patient age was 47 years (range 20-80) and 56% of the patients were premenopausal. ER and PR were positive in 50 and 60% of the patients, respectively. Overall, the ABO blood group distribution of the 294 HER2 (+) breast cancer patients was similar to that of the healthy blood donors (p=0.36). Likewise there was no correlation between blood type and ER, PR and menopausal status. Rh (-) patients had more frequent family cancer history and this difference was significant for patients with blood group B Rh (-) and O Rh (-) (p = 0.04). CONCLUSION In the present study we didn't find any relationship between HER2 status and ABO blood group and Rh factor. However, further studies with larger number of patients are needed to establish the role (if any) of blood groups in patients with breast cancer.

Abstract
AIM To evaluate the genetic, congenital and metabolic disorders which were detected concurrently with primitive neuroectodermal tumors (PNET) of the central nervous system in children. METHODS Medical records of 1030 children who were admitted to our department with diagnosis of brain tumor between 1975 and 2005 were reviewed retrospectively. Medulloblastoma and supratentorial PNETs were detected in 289 patients. They were reviewed for associated metabolic conditions, genetic and congenital defects. RESULTS One of the following conditions were detected in 10 patients with medulloblastoma and supratentorial PNETs: Neurofibromatosis type 1, Gorlin syndrome, juvenile polyposis coli, cancer prone syndrome of total premature chromatid separation and Fanconi anemia, bilateral retinoblastoma, L-2-hydroxyglutaric aciduria, Gilbert syndrome, gray platelet syndrome, cleft lip-palate and left renal agenesis. In the patients with multiple malignant diseases, cancer prone syndrome of total premature chromatid separation and Fanconi anemia, Gorlin syndrome and juvenile polyposis coli were diagnosed after diagnosis of the malignant tumors. Medulloblastoma was the first manifestation in the case with Gorlin syndrome. In case with retinoblastoma, pineal PNET was detected 2 months after diagnosis of retinoblastoma. Cleft lip-palate and L-2-Hydroxyglutaric aciduria were detected previously in the patients before their brain tumors whereas Gray platelet, Gilbert syndrome and left renal agenesis were diagnosed during treatment of medulloblastoma. CONCLUSION Associated genetic, metabolic and congenital conditions were detected in 3.5% of the cases. Thus the patients with PNET should be followed for these defects.

Abstract
This paper describes the design and performance of a new instrument to track temporal changes in physical parameters during the drying behavior of solutions, as well as curing of monomers. This real-time instrument follows in-plane and out-of-plane birefringence, weight, thickness, and surface temperature during the course of solidification of coatings and films through solvent evaporation and thermal or photocuring in a controlled atmosphere. It is specifically designed to simulate behavior of polymer solutions inside an industrial size, continuous roll-to-roll solution casting line and other coating operations where resins are subjected to ultraviolet (UV) curing from monomer precursors. Controlled processing parameters include air speed, temperature, initial cast thickness, and solute concentration, while measured parameters are thickness, weight, film temperature, in-plane and out-of-plane birefringence. In this paper, we illustrate the utility of this instrument with solution cast and dried poly (amide-imide)∕DMAc (Dimethylacetamide) solution, water based black paint, and organo-modified clay∕NMP (N-Methylpyrrolidone) solution. In addition, the physical changes that take place during UV photo polymerization of a monomer are tracked. This instrument is designed to be generic and it can be used for tracking any drying∕swelling∕solidification systems including paper, foodstuffs such as; grains, milk as well as pharmaceutical thin paste and slurries.

Abstract
OBJECTIVES Regardless of methicillin resistance, Panton-Valentine leucocidin (PVL)-positive Staphylococcus aureus isolates are associated with various types of infections and outbreaks. Limited data exist about the PVL content of S. aureus strains in Turkey. In this multicentre study, we aimed to assess the PVL positivity and antimicrobial susceptibilities of S. aureus isolates recovered from skin and soft tissue samples of both community and nosocomial origin in the study period, 2007-08. METHODS Two hundred and forty-two [92 community-acquired (CA) and 150 hospital-acquired (HA)] isolates were included in the study. Analysis of mecA and PVL was carried out using PCR. All isolates underwent susceptibility testing according to the CLSI. RESULTS Out of 242 isolates, 77 were mecA positive. PVL was not found among methicillin-resistant S. aureus (MRSA) isolates, but 8 (5.3%) HA methicillin-susceptible S. aureus (MSSA) and 14 (15.2%) CA-MSSA, mostly isolated from furuncles (71.4%), were positive for PVL. Among PVL-positive strains, the penicillin resistance rate was 90.9%. Low resistance rates, <10%, were detected for erythromycin, fusidic acid and co-trimoxazole. PVL-positive strains showed higher rates of susceptibility to erythromycin, gentamicin and rifampicin than negative isolates. CONCLUSIONS Based on the findings of this study, infection related to PVL-carrying CA-MRSA is not at an alarmingly high level, but population-based surveillance studies should be done to determine the real status.

Abstract
PURPOSE To study the efficacy and safety of radiotherapy (RT) with concomitant and subsequent temozolomide in comparison to RT alone in the treatment of patients with newly diagnosed glioblastoma multiforme (GBM) after brain surgical intervention. METHODS Twenty patients received cranial fractionated RT (60 Gy total dose: 2 Gy/day, 5 days/week, for 6 weeks) with concomitant oral temozolomide (75 mg/m(2)/day x 7 days/ week, for 6 weeks) followed by temozolomide monotherapy (200 mg/m(2)/day × 5 days every 28 days for 6 cycles). Another 20 patients received only cranial RT (Co-60 teletherapy, 60 Gy in 30 fractions). RESULTS At the end of the study the median time to progression free survival (PFS) was 13 months in the temozolomide plus RT treatment group and 5 months in the RT-alone group (p=0.0001). Median overall survival (OS) in the temozolomide plus RT and the RT-alone group was 19 and 11.5 months, respectively (p=0.0264). The main side effect in the temozolomide plus RT group was myelosuppression. Concomitant treatment resulted in grade 3 hematologic toxicity in 6 patients. CONCLUSION These data show that the combination of temozolomide, concomitant and subsequent to RT seems more effective than RT alone in patients with newly diagnosed GBM and that multimodality treatment is safe and well tolerated.

Abstract
Diet and lifestyle related to socioeconomic status emerged as risk factors for gastric cancer in several studies. However, the results were not always consistent with the socioeconomic status. The aim of this study was to evaluate the risk factors independent from education as a measure of socioeconomic status. Two hundred and fifty-three patients with gastric cancer diagnosed in 2005 and equal number of control subjects were interviewed for several characteristics and diet. Matching was done for age, gender, city of residence and also for the level of education. Despite these matching preferences, patients had significantly lower income when compared to the control subjects (P = 0.0001). Higher rate of patients were smoking more than 2 packs/day of cigarettes (P = 0.018). Also significantly higher rate of control subjects were using antibiotics (P = 0.002). Coffee (P < 0.0001), salad (P = 0.006), bread (P = 0.005), vegetable-derived cooking oil (P = 0.003) consumptions appeared as highly protective factors against gastric cancer in univariate analysis in the present trial. In multivariate analysis, significant risk reducing factors were bread (P = 0.005) and coffee consumption (P = 0.0001) other than the level income (P = 0.002). In conclusion, the goal of obtaining comparable socioeconomic status by including the level of education in the matching criteria was not met in our study because of the difference in income level. The only risk reducing factor that was not in accordance with income level was the unexpectedly higher rate of bread consumption in control group.

Abstract
BACKGROUND Behçet disease (BD) is a chronic, inflammatory, multisystemic vasculitic disorder with a wide spectrum of clinical presentations. The highest prevalence is seen in Turkey. Specific diagnostic tools are yet to be discovered; thus, the diagnosis relies on physicians being acquainted with the symptoms and signs of the disease. OBJECTIVE To investigate the epidemiologic characteristics of BD and to emphasize the typical clinical and laboratory characteristics. METHODS This was a retrospective analysis of all the BD patients attending the Ankara Numune Education and Research Hospital throughout the years 2001-4. Diagnosis of BD was made according to the International Study Group criteria. A total of 213 patients were evaluated with respect to family history, clinical features, pathergy test, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), antistreptolysin O, and ferritin levels. When assessing disease activity, the active clinical manifestations on the day of the examination were taken into account. Correlations were analyzed between sex and age distribution, age of onset, disease duration, and family history; and between family history and age of onset, pathergy, clinical manifestations, and laboratory parameters. Correlations were also evaluated between pathergy positivity and clinical manifestations, and laboratory parameters. Correlations between activity scores and age of onset, duration, sex, family history, and laboratory data were also analyzed. RESULTS The female : male ratio was 1.04, and the mean age of onset was 27 years. Family history did not affect age of onset or disease severity. Men presented with more active disease, and there was a weak but positive correlation between disease activity and CRP. No correlation was observed between duration and age of disease onset. The most common clinical presentations were oral aphthous lesions, genital ulcers, and skin lesions. Men more commonly presented with papulopustular lesions, pathergy positivity, and vascular, eye, and renal involvement, and women presented with arthritis/arthralgia more commonly than men. Vascular lesions, ESR, and CRP showed significant relationships with pathergy reaction. Eye involvement was not affected by age of onset. CONCLUSIONS We believe our results indicate that the pathogenesis of BD is multifactorial. Hormonal factors seem to be of some influence, while genetic background and environmental factors seem to be the major contributors. Infections seem to be among the triggering environmental factors. Predisposing genes may affect the influence of environmental factors. Prevalence studies should be carried out periodically in those countries with a high prevalence of BD to keep up with the changing dynamics of the disease, which may also shed light on the as-yet unknown pathogenesis of BD.
