Recent scoring systems predicting stone-free status after retrograde intrarenal surgery; a systematic review and meta-analysis

Introduction Several scoring systems and nomograms have been developed to predict the success of retrograde intrarenal surgery. But no meta-analysis for the performance of scoring systems has yet been performed. The aim of this study was to compare predictive ability of recent scoring systems for stone-free rate of retrograde intrarenal surgery. Materials and methods PubMed and Web of Science databases were searched systematically between April and May 2021. The scoring systems which were validated externally or studied at least by two different researcher groups were selected for further analysis. Of 59 records, 14 studies met the inclusion criteria (n = 4137). Area under curve (AUC) values of selected scoring systems were pooled in random or fixed effects. Thertest was used to quantify heterogeneity. Results Eight, 5, 8, 4 and 3 studies included in meta-analyses for the modified Seoul National University Renal Stone Complexity Score (S-ReSC), R.I.R.S., Resorlu-Unsal Score (RUS), S.T.O.N.E., and Ito's Nomogram, respectively. We found pooled AUC values 0.709 (95% CI 0.670-0.748), 0.704 (95% CI 0.668-0.739), 0.669 (95% CI 0.646 to 0.692), and 0.771 (95% CI 0.724 to 0.818), for first four of them, respectively. Heterogeneity was very high to pool AUC values for Ito's nomogram. Conclusions Although S.T.O.N.E. score showed higer pooled AUC value, this systematic review and meta-analysis has not revealed superiority of any scoring system. High heterogeneity between studies and dependencies between scoring systems make it difficult to design a comparative statistical model to generalize the findings. Also, limitations aside, neither scoring system has demonstrated good predictive/discriminative performance

Evoluation of childhood poisoning at our hospital

Amaç: Acil servislere başvurular içerisinde sayıları giderek artan zehirlenmelere dikkat çekmek ve hastanemize zehirlenme ile başvuran olguları değerlendirmek için bu çalışma planlanmıştır. Gereç ve Yöntem: Dr Behçet Uz Çocuk Hastanesine 1994 yılı Ocak-Mayıs ayları arasında zehirlenme nedeni ile başvuran 123 olgu geriye dönük olarak yaş, cins, alınan toksik maddenin türü, başvuru süreleri, başvuru şikayetleri, tedavi yöntemleri hastanede kalış süreleri açısından değerlendirilmişlerdir. Bulgular: Olguların %80'inin 5 yaşından küçük, erkek/kız oranının 1.2 olduğu saptanmıştır. Zehirlenmelerin sırasıyla ilaçlarla (%61), petrol türevi hidrokarbonlu bileşiklerle(%17), besinlerle (%7.2), organik fosforla (%6.5), fare zehiriyle (%4), CO gazıyla (2.4) ve kimyasal ajanlarla (1.7) olduğu tespit edilmiştir. Zehirlenme olgularının %95.2'si kaza sonucunda meydana gelmiş, %4.8'i istemli ilaç alımı şeklinde olmuştur. Sonuç: Zehirlenmeler daha çok 5 yaş altındaki çocuklarda görülmektedir. ılaçlar ve hidrokarbonlu bileşikler en sık çocukluk çağı zehirlenmelerine yol açan ajanlardır. Çocukların bu ajanlardan uzak tutulması bu tip zehirlenmeleri önleyecektir.Objective: The aim of this study is to evaluate childhood poisoning at our hospital and to draw the attention to the increasing incidence of childhood poisoning. Material and Method: In this retrospective study, the records of 123 cases who were hospitalized due to poisoning between January 1standMay 1stin 1994 were evaluated. Their age, sex, the type of material ingested, initial complaints, hospitalization time, the duration of hospitalization, treatment protocols were investigated. Results: Eighty percent of cases studied were younger than five years old with a male/female ratio of 1.2. The toxic agents ingested orexposedwere as follows: Drugs 61%, hydrocarbon compound 17%, food7.2%, organic phosphorus 6.5%, ratpoison4%, CO 2.4% and other chemicals 1.7%. Ninety five percent of cases wereexposed to the toxic agents accidentally whereas 4.8 % had ingested onpurpose. Conclusion: Poisoning is observed more commonly in children younger than five years old. Drugs and hydrocarbon compounds are the most common agents causing childhood poisoning. Keeping children away from these agents canprevent these types of poisoning

The contribution of cooperative learning approach to the awareness of environment in Geography

AbstractIn the 21st century, one of the most important environment problems caused by mankind is waste and storage of it. The waste directly exposed to the nature has adverse effects on both physical and human environment. People, considering themselves the most valuable of all creatures, leave the waste on behalf of controlling the nature not only destroy it but also the human health and economy. The single solution of this artificial deterioration is hidden in the intervention of human himself. Although there are some broadcasts by some press associations, humans’ being less consciousness on this issue prevents the complete success. The reasons why people cannot predictor even refuse to accept the negative effects of the waste they leave haphazardly to the environment is due to the lack of enough environmental conscious. We should certainly make everyone conscious of the environment to have a livable geographical milieu. Only the conscious people have the capacity to envisage a future dimension of a step. This research has aimed to make pre-service teachers conscious of the issues such as waste, recycling and recovery. Waste and recycling subject in Environment education course has been conducted in a cooperative approach to the students of social sciences teaching program of Necatibey Education Faculty of Balıkesir University and students have been asked to make some activities and finally they have been taken for an observation to rubbish dump parse institution in Balıkesir city. With the observation it has been aimed to give the pre service teachers the consciousness on the issues by the experts and laid the groundwork for their understanding of the different aspects of the problem. As a result it has been understood that there was a significant difference between pre and post attitudes of the students and also they have declared to have some positive behavior changes during and after their courses

Relation of neutrophil lymphocyte ratio with tumor characteristics in localized kidney tumors

Amaç: Nötrofil/Lenfosit oranının birçok ürolojik tümörde prognostik faktör olduğu gösterilmesine karşın lokalize böbrek tümörlerinde tümörün özellikleri ile ilişkisini araştırmayı amaçladık. Gereç ve Yöntemler: Kliniğimizde renal kitle tanısı ile opere edilen 125 hastanın laboratuvar ve patoloji sonuçları geriye dönük olarak incelendi. Tüm hastaların operasyon öncesi yapılan tam kan sayımlarından nötrofil/lenfosit oranı(NLR) tespit edildi. NLR'nin tümörün boyutu, tarafı, lokalizasyonu, histolojik tipi ve Fuhrman derecesi arasındaki ilişki istatistiksel olarak değerlendirildi. Bulgular: Preoperatif hesaplanan NLR ile hastaların cinsiyet ve yaş faktörleri, tümörün tarafı, lokalizasyonu, boyutu ile istatistiksel olarak anlamlı bir ilişki saptanmadı (p>0,05). Ayrıca tümör histopatolojilerine göre benign ve malign olarak, malign tümörlerde ise berrak hücreli olan ve olmayan olarak ikili gruplandırıldıklarında da NLR ile gruplar arasında istatistiksel olarak anlamlı bir ilişki izlenmedi (p>0,05). Berrak hücreli tümör patoloji raporlarından elde edilen Fuhrman dereceleri ile NLR arasında da istatistiksel olarak anlamlı bir sonuç saptanmadı (p>0,05). Sonuç: NLR'nin böbrek tümörlerinde diğer prognostik faktörlerden bağımsız bir değişken olduğu düşünülmesine rağmen literatürdeki farklı sonuçlardan dolayı daha kapsamlı geniş çalışmalara ihtiyaç vardır.Aim: Considering that neutrophil/lymphocyte ratio is indicated as prognostic factor in many urologic neoplasms, the purpose of this paper is to examine the relation between this ratio and characteristics of tumors in localized kidney tumors. Material and Methods: Laboratory and pathology results of 125 patients operated in our clinic with the diagnosis of renal lump were examined retrospectively. Neutrophil/lymphocyte ratios (NLR) of all patients were detected by an examination of pre-operation complete blood cell counts. The relations between NLR and size, side, location, histological type and Fuhrman degree of tumor were assessed statistically. Findings: Statistically significant relations could not be detected among preoperative NLR and sex and age of patients and size, side and location of tumor (p<0.05). Also, when tumors were divided into two as benign and malign and malign ones were grouped into two as tumors with and without clear cells, statistically significant relations could not be reported between NLR and these groups (p>0.05). A statistically significant relation could not be found between NLR and Fuhrman degrees obtained from clear cell tumor pathology reports (p>0.05). Conclusion: Although it is thought that NLR is a variable independent from the other prognostic factors in the kidney tumors, more comprehensive studies are needed due to different results available in the literature
