The 33-year Retrospective Analysis of Esophageal Carcinomas: CerrahpaĹźa Experience
Aim:Esophageal cancer is a fatal disease where the majority of patients are diagnosed at an advanced stage. In this study, we aimed to present the demographic and clinicopathological characteristics of patients who were operated for esophageal cancer.Materials and Methods:A total of 847 patients who underwent surgery, chemoradiotherapy, or palliative procedures for esophageal pathology between the years of 1985 and 2018 were retrospectively analyzed. Age, gender, tumor location, histopathology, surgical technique, and chemoradiotherapy history of patients were analyzed.Results:In the study, 488 patients were male (60.5%) and 319 were female (39.5%). The ratio of males and females was 1.52. The average age was 58.6 years, and 80.1% were older than 50 years. The most common pathological material obtained was squamous cell carcinoma (67.5%), followed by adenocarcinoma (27.7%). Total esophagectomy was performed in 435 patients; distal esophagectomy was performed in 38 patients. Transhiatal esophagectomy (n=271, 62.2%) was the most common procedure that was performed.Conclusion:Esophagectomy is the primary treatment modality for esophageal cancers. When determining the optimal treatment, appropriate patient selection, staging, and risk assessment should be made. Patient-specific treatment should be planned with a multidisciplinary approach
Magnetic resonance imaging based kidney volume assessment for risk stratification in pediatric autosomal dominant polycystic kidney disease
IntroductionIn the pediatric context, most children with autosomal dominant polycystic kidney disease (ADPKD) maintain a normal glomerular filtration rate (GFR) despite underlying structural kidney damage, highlighting the critical need for early intervention and predictive markers. Due to the inverse relationship between kidney volume and kidney function, risk assessments have been presented on the basis of kidney volume. The aim of this study was to use magnetic resonance imaging (MRI)-based kidney volume assessment for risk stratification in pediatric ADPKD and to investigate clinical and genetic differences among risk groups.MethodsThis multicenter, cross-sectional, and case-control study included 75 genetically confirmed pediatric ADPKD patients (5–18 years) and 27 controls. Kidney function was assessed by eGFR calculated from serum creatinine and cystatin C using the CKiD-U25 equation. Blood pressure was assessed by both office and 24-hour ambulatory measurements. Kidney volume was calculated from MRI using the stereological method. Total kidney volume was adjusted for the height (htTKV). Patients were stratified from A to E classes according to the Leuven Imaging Classification (LIC) using MRI-derived htTKV.ResultsMedian (Q1-Q3) age of the patients was 6.0 (2.0–10.0) years, 56% were male. There were no differences in sex, age, height-SDS, or GFR between the patient and control groups. Of the patients, 89% had PKD1 and 11% had PKD2 mutations. Non-missense mutations were 73% in PKD1 and 75% in PKD2. Twenty patients (27%) had hypertension based on ABPM. Median htTKV of the patients was significantly higher than controls (141 vs. 117 ml/m, p = 0.0003). LIC stratification revealed Classes A (38.7%), B (28%), C (24%), and D + E (9.3%). All children in class D + E and 94% in class C had PKD1 variants. Class D + E patients had significantly higher blood pressure values and hypertension compared to other classes (p > 0.05 for all).DiscussionThis study distinguishes itself by using MRI-based measurements of kidney volume to stratify pediatric ADPKD patients into specific risk groups. It is important to note that PKD1 mutation and elevated blood pressure were higher in the high-risk groups stratified by age and kidney volume. Our results need to be confirmed in further studies

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespa
The effects of ultra-early clipping on survival and neurological outcome in poor-grade aneurysmal subarachnoid haemorrhage = Az ultrakorai klipelés hatása a túlélésre és a neurológiai kimenetekre súlyos stádiumú, aneurysmaruptura okozta subarachnoidealis vérzés esetén
Background and purpose – European Stroke
Organisation guidelines advise treating aneurysmal subarachnoid haemorrhage (aSAH) as early as possible.
However, the optimum timing along with its beneficial
effects is controversial. Therefore, we aimed to investigate
the effects of ultra-early clipping on neurological outcomes
and survival in poor-grade aneurysmal subarachnoid
haemorrhages.
Methods – This retrospective study included all poorgrade aneurysmal subarachnoid haemorrhage patients
treated by ultra-early surgical clipping at Trakya University
Hospital between January 1, 2001, and December 31,
2020. We analysed the outcome and mortality data of
these patients. Specifically, we evaluated the effects of
ultra-early clipping on outcomes, defined as within six
hours of the onset of symptoms.
Results – From 813 records, 212 met our inclusion criteria. Of these, 117 (55.2%) were female and 95 (44.8%)
male. The mean age was 58.3 ± 13.7 years. Glasgow
Outcome Scale scores differed significantly between age
groups, subarachnoid haemorrhage grades, those who
did and did not rebleed, and those who did or did not
suffer from vasospasms. A beneficiary relationship was
found between ultra-early clipping and mortality among
patients. Furthermore, favourable outcomes were significantly more frequent in the ultra-early clipping group.
Conclusion – The aSAH patients treated at our hospital
who received ultra-early clipping had significantly lower
mortality rates and more favourable outcomes. The difference was significant among those treated during the last
decade and among patients younger than 50. = Háttér és cél – A European Stroke Organisation irányelvei
szerint az aneurysmaruptura okozta subarachnoidealis vérzést (aSAH) a lehető leghamarabb kezelni kell. Mindazonáltal, a beavatkozás optimális ideje, és az általa elérhető
előnyök egyelőre még nem tisztázottak. Célunk ezért
az volt, hogy megvizsgáljuk az ultrakorai klipelés hatását
a túlélésre és a neurológiai kimenetekre súlyos stádiumú,
aneurysmaruptura okozta subarachnoidealis vérzések esetén.
MĂłdszerek – RetrospektĂv vizsgálatunkba bevontuk mind -
azokat a súlyos stádiumú, aneurysmaruptura okozta subarachnoidealis vérzésben szenvedő betegeket, akiket
2001. január 1. és 2020. december 31. között a Trakya
Egyetemi KĂłrházban ultrakorai klipelĂ©ssel kezeltek. ElemeztĂĽk a bevont betegek neurolĂłgiai kimeneteit Ă©s mortalitási adatait. ÉrtĂ©keltĂĽk az ultrakorai klipelĂ©s (definĂciĂł szerint a tĂĽnetek jelentkezĂ©se utáni 6 Ăłrán belĂĽli beavatkozás) kimenetekre gyakorolt hatását.
Eredmények – 813 beteg közül 212 felelt meg a bevonási
kritériumoknak. A bevont betegek 55,2%-a nő (n=117),
44,8%-a férfi (n=95) volt. Az átlagos életkor 58,3 ± 13,7
volt. A Glasgow Kimeneti Skála pontszámai szignifikánsan
különböztek az életkori csoportok, a subarachnoidealis
vérzés súlyossága, az ismételt vérzés, illetve a vasospasmus
előfordulása szerint. Az ultrakorai klipelés hatására
csökkent a mortalitás, és a többi kedvezô kimenet is szignifikánsan gyakoribb volt ebben a csoportban.
Következtetés – Azon aSAH-betegek körében, akiket
kórházunkban ultrakorai klipeléssel kezeltünk, szignifikánsan alacsonyabb mortalitás alakult ki, és egyéb kimeneteik
is szignifikánsan jobbak lettek. A különbség szignifikáns
volt a legutóbbi évtizedben (2010–2020) kezeltek és
az 50 évesnél fiatalabbak esetén
Urban Seismic Risk Reduction and Mitigation Strategies in Turkey
Since the early ages of humankind, safety and security has been a critical
issue against the forces of nature. However, history has always proven the
power of nature over humankind in certain regions on Earth for centuries.
Indeed, this is a never-ending war between Earth and its inhabitants, namely
us, human beings. Humankind’s organization (cities, roads, lifelines etc.) in
the nature has never been perfect within the view of environmental pollution
and excessive consumption of the resources. Particularly, the quality of civil
engineering design and practice is strongly affected from the social and
economic background of the country. The societies in rapid development
claim excessive demands in terms of housing and transportation. Such
demands may create vulnerable urban areas if the economic and social
conditions are not in balance or harmony. Thus, nature should not be blamed
as the scapegoat in the regions where disasters claim human and economic
losses. In fact, the reason for the losses is nothing else than humankind itself.
A rational question arises then about how to overcome human and economic
loss due to natural disasters. The idea of determining the most vulnerable
items in urban areas and reconstructing with the most reliable equivalents
may seem very challenging. Even though the macroeconomic implications
are very complex, reconstructing the items in densely populated areas is the
most effective mitigation action against disasters in the short term. Having
learnt lessons from the major earthquake disasters in the heart of the industry
and mostly dense urban areas, Turkish government has drawn a long strategic
road map in the risk perception and the disaster mitigation strategy for almost
all the community services and the infrastructure. The development of
awareness against disasters has become part of formal education at all ages.
The National Disaster Management system was reorganized from scratch and the capabilities improved by providing additional financial and human
resources. All school and hospital buildings in Ä°stanbul were assessed in terms
of seismic safety. Those found inadequate were demolished and then
reconstructed. In addition, a law on urban renewal of the seismic risk areas
was enacted in 2012 allowing the licensed engineering offices to assess the
seismic risk of residential buildings at the request of the house owners. If the
assessment report is approved by the local municipality, the building is set to
demolish within 60 days following the legal notice to the property owners.
Disagreeing owners have the right to get the assessment re-evaluated by the
independent peer reviewers. In the case of demolition, the house owners are
eligible to receive 12 months of rental support from the government. During
the time period 2012 to 2019, more than 120 000 buildings were assessed and
74% of them were demolished, the majority of the latter were in Ä°stanbul area
where a major earthquake is expected within the following decades. This
chapter is intended to explain one of the most comprehensive and challenging
disaster mitigation strategies being applied in Turkey based on experience
since the 1999 earthquakes.Published19-426T. Studi di pericolositĂ sismica e da maremot
