Cancer Incidence In Cyprus

Original Article Asian Pasific Organization, Volume 9, Issue 9, 2008, Pages 725-732

Abstract

Cancer incidence in North Cyprus (NC), deemed an interesting epidemiological case due to possible contrasting prevailing factors in relation to South and North Europe (SE and NE), was evaluated for the period 1990-2004. Age standardized rates (ASRs) and average age of incidence (AAI) values were determined for 12 different cancers, separately for males and females. Annual trends were analyzed using linear regression slopes. Absolute values were compared by two-tailed t-tests. The order of prevalence for incidences of male (M) cancers were: lung, skin, colorectal, prostate, brain, bladder, liver and stomach. Similarly, for females (F) they were: breast, gynaecological, skin, colorectal, lung, liver, brain, stomach and bladder. The following cancer cases were more common than in SE and NE: lung (M) and skin (both genders). Breast (F), prostate, stomach (F), bladder (both sexes), cervix and corpus were less frequent; the rest were comparable. There was no difference in the annual trends of ASR or AAI for NC, compared with SE or NE. Thus cancer incidence in NC shares many quantitative features with the rest of Europe. The worst cases could be improved by reducing smoking and protection from the sun.

Mathematical Models for Human Cancer Incidence Rates - Application to Results from Europe, including North Cyprus

Original Article Asian Pacific J Cancer, Volume 10, Issue 10, 2009, Pages 325-335

Abstract

The overall cancer incidence rate declines at very old age. Possible causes of this decline include the effects of cross-sectional data that transform cohort dynamics into age patterns, population heterogeneity that selects individuals susceptible to cancer, a decline in some carcinogenic exposure in older individuals, underdiagnosis, and the effects of individual aging that slow down major physiological processes in an organism. Here several mathematical models contributing to the explanation of this phenomenon are discussed with extension of the Strehler and Mildvan model of aging and mortality to the analysis of data on cancer incidence at old age (data source: International Agency for Research on Cancer). The model can help explain the observed time trends and age patterns of cancer incidence rates.

CANCER AND CARDIVASCULAR DISEASE MODELLING IN NORTH CYPRUS

Original Article IJRRAS, Volume 2, Issue 2, 2010, Pages 145-172

Abstract

Age-adjusted mortality in 2004 was essentially unchanged from the early 1990s. At the same time, age-adjusted mortality rates from cardiovascular disease have fallen quite dramatically. Since the causes underlying cancer and cardiovascular disease are likely to be correlated, the decline in mortality rates from cardiovascular disease may be somewhat responsible for the rise in cancer mortality. It is natural to model mortality with more than one cause of death as a competing risks model. Such models are fundamentally unidentified, and it is therefore difficult to get a clear picture of the progress in cancer. This paper derives bounds for aspects of the underlying distributions under a number of different assumptions. Most importantly, I do not assume that the underlying risks are independent, and impose weak parametric assumptions in order to obtain identification. The theoretical contribution of the paper is to provide a framework to estimate competing risk models with interval data and discrete explanatory variables, both of which are common in empirical applications. I use our method to estimate changes in cancer and cardiovascular mortality since 1990. The estimated bounds for the effect of time on the duration until death for either cause are fairly tight and we find that trends in cancer show much larger improvements than previously estimated. For example, we find that time until death from cancer increased by about 10% for NC males and 20% for NC women.


Özet

Yaşa göre düzeltilmiş 2004 yılında mortalite 1990'lı yılların başından itibaren esasen değişmemiştir. Aynı zamanda, kardiyovasküler hastalık yaşa göre düzeltilmiş ölüm oranları oldukça dramatik düşmüştür. Kanser ve kardiyovasküler hastalık yatan nedenleri ilişkili olması muhtemeldir beri, kardiyovasküler hastalık ölüm oranlarında düşüş kanser ölümlerinde artış için biraz sorumlu olabilir. Bir yarışan riskler modeli olarak ölüm birden fazla nedeni ile mortalite modeli doğaldır. Bu tür modeller temelde tanımlanamayan vardır ve kanser ilerleme net bir resim elde etmek zordur. Bu yazıda, farklı varsayımlar altında yatan dağıtımları sayıda yönleri için sınırları türemiştir. En önemlisi, ben altta yatan risklerin bağımsız olduğunu kabul ve kimlik elde etmek amacıyla zayıf parametrik varsayımlar getirmez. Kağıdın teorik katkısı ampirik uygulamalarda yaygın olan, her ikisi de veri aralığı ve ayrık açıklayıcı değişkenler ile risk modelleri rekabet tahmin etmek için bir çerçeve sağlamaktır. Ben de neden ölüm oldukça sıkı kadar 1990 yılından bu yana süre zaman etkisi tahmini sınırları kanser ve kardiyovasküler mortalite değişiklikleri tahmin etmek için bizim yöntemini kullanın ve daha önce tahmin edilenden daha kanser eğilimler çok daha büyük gelişmeler gösteriyor ki bulmak. Kanserden ölüm NC erkeklerde yaklaşık% 10 ve NC kadınlarda% 20 artarak kadar Örneğin, o zaman bulabilirsiniz.

Kuzey Kıbrıs Türk Toplumunda Güneşten Korunma: İlkokul Çağı Çocukları ve Ailelerinin Güneşten Korunma ile İlgili Bilgi, Tutum ve Davranışları

Original Article Türkderm, Volume 46, Issue 2, 2012, Pages 121-129

Abstract

Background and Design: Skin cancer is the most common cancer in the Turkish Republic of North Cyprus (TRNC) according to the last 25 years' statistics of the country. The harmful effect of ultraviolet light is well-known and exposure especially in childhood has an important role in the pathogenesis. Having healthy individuals in sunny countries like the TRNC is related with the public knowledge and early gained behaviors. This study aims to determine the children’s knowledge, attitude and behaviors towards sun, as well as the impact of familial attitudes on the behaviors of the children.Materials and Methods: Questionnaires about sun protection were applied to the children and their families in the most crowded elementary school in the TRNC. Seven questions for knowledge, 7 for attitudes, and 5 for behaviors of families as well as 6 questions for the children were prepared. Results: Forty-one percent of families were aware of the need of regular and continuous sun protection, while 21.8% thought sun protection is important only in early infancy. Families reported media (44.5%) as the most common source of their knowledge regarding sun protection. Most of the families thought that they had performed sufficient research and had applied sun protection correctly, whereas 33% of the families reported lack of application in daily life. Almost 65% of the families reported a “need for additional knowledge” and 85.4% were eager to join educations. Most of the children had knowledge about sunscreens, whereas 2.7% had no idea. The relation between knowledge, attitude and behaviors of parents and children was evaluated and found to be significant statistically (p<0.001). The consciousness level of children increases with the parental consciousness. Conclusion: The results of this study revealed that the Turkish population in the NC is aware of sun protection but needs more education. The parental impact on children's behaviors was shown and the necessity of early education starting in the family was emphasized.

Özet

Amaç: Kuzey Kıbrıs Türk Cumhuriyeti (KKTC)’nde son 25 yıla ait istatistiklere bakıldığında deri kanserleri bu ülkede en sık görülen kanserdir. Patogenezde güneş ışınlarının olumsuz etkileri bilinmekte olup, özellikle çocukluk döneminde maruz kalınan güneş ışınlarının rolü üzerinde durulmaktadır. KKTC gibi güneşli ülkelerde genç nüfusun sağlıklı bireyler olarak yetişmeleri, erken dönemde edindikleri doğru bilgi ve alışkanlıklara bağlıdır. Bu çalışmada KKTC'de çocukların ve ailelerinin güneşten korunma ile ilgili bilgi, tutum ve davranışlarının saptanması, ailelerin eğitimi, bilgi, tutum ve davranışlarının çocuklarının bilgi tutum davranışları üzerindeki etkisi ve ilişkisinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: KKTC'de en çok öğrenciye sahip olan ilkokuldaki öğrencilere ve ailelerine güneşten korunma ile ilgili anket uygulanmıştır. Ailelerin bilgi düzeyi için 7, tutum için 7 ve davranışları için 5 soru, çocuklara 6 soru hazırlanmıştır. Bulgular: Ailelerin %41,1’i güneşten korunmak için sürekli ve düzenli korunma gerektiğini biliyorken, %21,8 i sadece erken bebeklik döneminde korunmanın önemli olduğunu düşünmektedir. Ailelerin büyük çoğunluğunun (%44,5) bilgi kaynağını medya araçları oluşturmaktadır. Ailelerin çoğu gerekli araştırmaları yaptığını ve korunmayı doğru olarak uyguladığını düşünürken, %33’ü yeterli bilgisi olsa da tam olarak uygulayamadığını bildirmiştir. Ailelerin %64.8’i güneşten korunma konusunda daha çok bilgiye ihtiyacı olduğunu belirtirken, %85,4’ü eğitimlere katılmaya istekli olduklarını belirtmişlerdir. Çocukların çoğu (%96,3) “güneşten koruyucu krem” i bilmekte iken, sadece %2,7 bilmediğini belirtmiştir. Ebeveynlerin bilgi, tutum ve davranışlarıyla çocukların davranışları arasındaki ilişki değerlendirilmiş ve istatitiksel olarak anlamlı bulunmuştur (p<0,001). Anne ve babaların bilinçlilik düzeyi arttıkça çocukların da artmaktadır. Sonuç: Bu çalışma ile Kuzey Kıbrıs Türk toplumunun güneşten korunma ile ilgili bilinçli olduğu, ancak daha çok eğitici faaliyete ihtiyaç duyulduğu ortaya konulmuştur. Çocukların davranışları üzerinde ailenin belirgin etkisi gösterilerek eğitime çocukluk döneminde ve aile ile birlikte başlanmasının gerekliği gösterilmiştir.

Effect of isotretinoin on prothrombin time (PT), international normalized ratio (INR), and activated partial thromboplastin time (aPTT).

Original Article J Dermatolog Treat, Volume 24, Issue 4, 2013, Pages 272-274

Abstract

Patients with severe acne may need surgical interventions during on isotreinoin treatment and it is critical for the surgeon to consider the possible effects of this medication on coagulation systems. There are few reports about the effects of isotretinoin treatment on coagulation parameters. The aim of this study is to determine the changes in Prothrombin Time (PT), International Normalized Ratio (INR), and activated partial thromboplastine time (aPTT) during isotretinoin treatment. Fiftyone patients with severe acne whom initiated isotretinoin treatment included in the study. PT, aPTT and INR values of 51 severe acne patients were evaluated during routine pre-treatment biochemical analysis. Only patients with normal values included in the study. The results of before and after 1 month treatment were compared statistically. There were no statistically difference in ALT, AST, PT and INR values after treatment. A significant increase in aPTT was detected. The INR values, which is more trusted and safe, showed no difference. Our results indicate that isotretinoin seems to have no effect on these coagulation parameters. In conclusion, isotretinoin seems to have no increased risk of bleeding, in otherwise healthy acne patients. It seems that in case of a surgery during isotretinoin usage, the drug might be considered to be safe from the point of increasing bleeding tendency.

Bu çalışmanın amacı, protrombin zamanında değişiklikler (PT), uluslararası normalleştirilmiş oran (INR) belirlemektir ve izotretinoin tedavisi sırasında parsiyel tromboplastin zamanı (aPTT). 51 şiddetli akne hastalarının PT, aPTT ve INR değerleri rutin tedavi öncesi biyokimyasal analizler sırasında değerlendirildi. Normal değerler olan hastalar çalışmaya dahil edildi. Önce ve sonra 1 ay tedavi sonuçları istatistiksel olarak karşılaştırıldı. Tedaviden sonra hayır demek alanin aminotranferease (ALT) istatistiksel olarak anlamlı bir değişiklik, aspartat aminotransferaz (AST), PT ve INR değerleri vardı. APTT önemli bir artış tespit edilmiştir. Daha güvenilir ve güvenli INR değerleri, hiçbir farklılık göstermedi. İzotretinoin bu koagülasyon parametreleri üzerinde hiçbir etkisi var gibi görünüyor.

KNOWLEDGE, ATTITUDES AND BEHAVIOUR TOWARDS SEXUALLY TRANSMITTED DISEASES IN TURKISH CYPRIOT ADOLESCENTS

Original Article Cent Eur J Public Health, Volume 21, Issue 1, 2013, Pages 54-58

Abstract

Background: The incidence of sexually transmitted diseases (STDs) is increasing among adolescents all around the world. There may be differences in knowledge and attitudes among different cultures and ethnic populations. The aim of this study is to determine knowledge, attitudes and behaviour of Turkish Cypriot adolescents related to STDs. Objectives: To assess knowledge of STDs, attitudes towards sexual behaviour and STDs among the secondary school students. Methods: A cross sectional study, with a sample size of 423 students, was conducted by using a semi-structured questionnaire. Simple random sampling method was applied during the selection of the sample. Results: The mean age of all participants was 15.61±1.22, 211 (49.88%) of them were male and 212 (50.12%) female. The majority of students (91.25%) stated that they had some knowledge about STDs; hovewer, 8.75% of the participants did not have any knowledge at all. Most of them, 42.32% described school as a source of information on STDs, nonetheless, only 7.57% of the group cited health care professionals as the information source. The majority of students (97.64%) has never been treated for STDs. Among 423 applicants, 93.14% indicated that they would have appreciated information about STDs during the high school years. Conclusions: There is a general understanding that the students are willing to participate and are in need of seminars that will be held about STDs during high school attendance. Furthermore, awareness raising educational events on this matter should be reviewed and revised in order to come up with more powerful ways of fighting against STDs transmission in this young population group of Turkish Cypriot (TC) community.

Statistical Analysis of Tuberculosis in Jigawa State, North- Western Nigeria

Original Article Malays. j. med. biol. res., Volume 2, Issue 3, 2015, Pages 327-241

Abstract

Studies on Tuberculosis (TB) in Jigawa, a Northwestern state in Nigeria, is very scarce as Tuberculosis and Leprosy Control Center in the state started functioning properly only recently in 2009. Since then, there has been a hike in the number of TB patients visiting the center. This study is conducted to analyze the incidence of Tuberculosis in the state. Data used is obtained from Tuberculosis and Leprosy Control Center, Ministry of Health, Jigawa State, Nigeria. Questioners are used for the collection of the available data for the period of six years (2009–2014). Linear regression is used to analyze the trend of the disease from the same period. Trends within various age groups were recorded. HIV co–infection is analyzed and its trend is also recorded over the years. Gender parity is also analyzed using a t-test. There is an increase in the number of patients from 2009 to 2014. Out of the 9590 patients seen in the period, 6538 (68.18 %) are males and3052 (31.82%) are females. At-test is used to show the significance in the difference between the number of males and females. It is also found that, there is an increase in the number of HIV co-infection over the said years. The study shows the prevalence of TB is highest among the age group of 25 – 34 (30.15%). The commonest type of TB in the population was smear positive pulmonary TB, with 5853 patients (61.03%). TB in Jigawa state was found to be significantly increasing. Out of all the 9590 patients seen at the center, 6538 (68.18 %) are males and3052 (31.82%) are females. HIV co - infection with Tuberculosis occurred in 9.94% of the patients considered. This study shows a high percentage of infection: 30.14% between the age group of 25-34.In general, Pulmonary TB has a higher prevalence of 95.69% compared to Extra Pulmonary TB that has 4.31%.

CANCER MORTALITY IN NORTH CYPRUS 1995-2007

Original Article INDIAN JOURNAL OF MEDICAL SCIENCES, Volume 68, Issue 1, 2016, Pages 32-35

Abstract

BACKGROUND: From 1995 to 2007, age-standardized total cancer mortality rates in the North Cyprus (NC) fell by around 9% in both sexes. Available cancer mortality data in Europe up to 2002 allow a first check of the forecast of further declines in cancer mortality. MATERIALS AND METHODS: We considered trends in age-standardized mortality from major cancer sites in the NC during the period 1995-2007. RESULTS: In women, total cancer mortality declined by 23% from 92/100 000 to 75/100 000 between the years 1995-2007. Corresponding figures for men were 85/100 000 to 66/100 000, corresponding to falls of 23% from 1995 to 2007. Lung cancer in men declined from 20/100 000 around 1995 to 16 around 2007 (-20%). In women, lung cancer mortality was 2/100 000 and there were no changes between the years 1995 and 2007. Bladder cancer declined by 25% for both men and women from 1995 to 2007. Breast cancer mortality declined from 18/100 000 around 1995 to 15/100 000 (-16%) in 2007. Prostate cancer was approximately stable until 2000, but declined from 8 to 6 (-25%) in 2007. CONCLUSIONS: Despite the persisting rises in female lung cancer in the EU, the recent trends in cancer mortality in the NC are encouraging and indicate that a 9% reduction in total cancer mortality from 1995 to 2007 is realistic and possible.

Global Stability Analysis of Oseltamivir–resistant Influenza Virus Model

Original Article Procedia Computer Science , Volume 102, Issue 10, 2016, Pages 333-341

Abstract

We study a new model describing the dynamics of both Oseltamivir resistant and non- resistant Influenza virus. Incorporated in the model is oseltamivir drug for the non- resistant strain and nalidixic acid or dorzolomide drugs for the resistant strain. The basic reproduction ratios R0 are determined using the next generation matrix. The local and global asymptotic stability of the disease free equilibrium are determined and shown to only exist if R01?1 and R02?1. Local and global asymptotic stability of the endemic equilibria exist if R01>1 and R02>1. Lyapunov function was used to show the global stabilities.

Morphometric analysis of the infraorbital foramen, canal and groove using cone beam CT: considerations for creating artificial organs

Original Article The International Journal Of Artificial Organs, Volume 39, Issue 1, 2016, Pages 28-36

Abstract

Purpose The aim of this study was to examine the anatomy and variations of the infraorbital foramen and its surroundings via morphometric measurements using cone beam computed tomography (CBCT) scans derived from a 3D volumetric rendering program. Methods 354 sides of CBCT scans from 177 patients were examined in this study. DICOM data from these images were exported to Maxilim® software in order to generate 3D surface models. The morphometric measurements were done for infraorbital foramen (IOF), infraorbital groove (IOG) and infraorbital canal (IOC). All images were evaluated by 1 radiologist. To assess intra-observer reliability, the Wilcoxon matched-pairs signed rank test was used. Differences between sex, side, age and measurements were evaluated using chi-square and paired t-test and measurements were evaluated using 1-way ANOVA tests. Differences were considered significant when p<0.05. Results The most common shape was oval for IOF and parallel for IOC without any accessory foramen. The results showed that females have smaller dimensions for the measurements between the two foramen rotundum (FR), FR-IOF, sella-FR, center of the IOF (cIOF)-nasion (N), cIOF-NB (nasion-B) (p>0.05). No significant difference was found according to age groups (p>0.05). Conclusions These results provide detailed knowledge of the anatomical characteristics in this particular area. CBCT imaging with lower radiation dose and thin slices can be a powerful tool for anesthesia procedures like infra orbital nerve blocks, for surgical approaches like osteotomies and neurectomies and also for generating artificial prostheses.

Cone beam computed tomography evaluation of mandibular canal anterior loop morphology and volume in a group of Turkish patients

Original Article Biotechnology & Biotechnological Equipment, Volume 30, Issue 2, 2016, Pages 346-353

Abstract

The aim of the present study was to assess the presence and course of the anterior loop in the mental foramen region according to age and gender, using cone beam computed tomography (CBCT). Both the right and left sides were retrospectively studied in 141 patients ( n D 282). Axial, sagittal, cross-sectional and panoramic images were evaluated and three-dimensional images were reconstructed and evaluated as necessary. The morphology, course and length of the anterior loop were measured. The reliability and reproducibility were assessed based on the intraclass correlation coef fi cient (ICC) and the coef fi cient of variation. An anterior loop was found in about 86% of the scans. The mean anterior loop proximal edge was 3.15 mm and the mean distance between the buccal border of the anterior loop and buccal alveolar wall was 2.24 mm. The mean volume of the mandibular canal was 1140 mm 3 and the mean volume of the anterior loop was 90 mm 3 . Statistically signi fi cant difference was found in male patients in terms of the canal and anterior loop volume ( p < 0.05). A high prevalence of anterior loop was detected by CBCT imaging, with predominance in female patients. Clinicians should be careful during implant or bone surgery procedures to avoid possible complications, with special emphasis on patient age, using this imaging modality that involves use of less radiation.

Comparison of linear and angular measurements in CBCT scans using 2D and 3D rendering software

Original Article Biotechnology & Biotechnological Equipment , Volume 30, Issue 4, 2016, Pages 777-784

Abstract

The aim of this study was to compare the reliability of both linear and angular measurements conducted on two-dimensional (2D) lateral cephalometric images and three-dimensional (3D) cone-beam computed tomography-generated cephalograms derived from various rendering software. Pre-treatment cephalometric digital radiographs of 15 patients and their corresponding cone beam computed tomographic images were randomly selected. Vista Dent OC as 2D, In vivo 5.1.2, Maxilim and Romexis software were used to generate cephalograms from the CBCT scans (NewTom 3G, QR Verona, Italy). In total, 19 cephalometric landmarks were identified and 18 widely used (11 linear, 7 angular) measurements were performed by an independent observer. Mann–Whitney and Kruskall–Wallis H tests were also used to compare the four methods (p < 0.05). Intra-class correlation coefficients (ICCs) were used to examine the intra-observer reliability.
