Hazardous radionuclides are produced during normal operation of nuclear power plants and research facilities. They can also spread to the environment due to fallout from nuclear accidents and nuclear weapon tests. The removal of hazardous radionuclides and the safe management of radioactive waste are of vital necessity. Natural minerals have been widely used for the removal of heavy metals and radionuclides because of their low cost, high capacity and radiation resistance properties. Turkey has an abundant natural mineral deposits. These deposits include clinoptilolite, bentonite, montmorillonite, kaolinite, vermiculite, illite, red clay, sepiolite, diatomite, perlite and volcanic tuff. Within the scope of this review, Turkish minerals were classified as three main groups as; zeolites, clay minerals and other minerals. The review consists of sections on the general properties of natural minerals such as zeolites and clays, the characteristics of Turkish minerals, and the adsorption performance of these minerals against some radionuclide ions (Sr, Cs, U, Th and Po).

Objective: Recently, achieving good cosmetic results for patients with gastroschisis has gained popularity, as since the visceral organs can be safely positioned into the abdominal cavity. We aimed to evaluate patient outcomes while focusing on the cosmetic results to contribute to the limited amount of data on this subject in the literature.Methods: From January 2005 to May 2018, patients operated on for gastroschisis in a single institution were evaluated retrospectively.Results: Twenty-two patients with gastroschisis were treated (10 females/12 males). The mean gestational age was 38.2±2.1 weeks. The mean birth weight was 2256.9±418.2 g. Eleven patients were diagnosed prenatally. Five patients had complex gastroschisis. Others presented with necrosis (n=3), perforation (n=3), volvulus (n=1) and jejunal atresia (n=1). Primary closure (n=16) and staged closure (n=6) were performed. Patients needed mechanical ventilation and total parenteral nutrition for 3.7±1.0 days and 24.3±9.7 days, respectively. Enteral feeding was started at 15.9±10.5 days. The duration of hospitalisation was 36.7±13.3 days. Three patients died from sepsis and multi-organ failure.Conclusion:We believe that performing appropriate gastroschisis surgery at the same hospital without transferring to another centre is the main factor in achieving a successful outcome. Good cosmetic results and visceral function were achieved in this study in 86.3% patients.

In this study, strontium nitrate extraction from celestite in nitric acid solutions was investigated using the leaching method. The influences of acid concentration, solid-to-liquid ratio, stirring speed, and reaction temperature on the leaching of strontium from celestite concentrate were studied. The results showed that the leaching rate increased with increasing acid concentration, stirring speed, and temperature and decreased with increasing solid-to-liquid ratio. The particle size was fixed in all of the dissolution experiments. The results showed that the stirring speed and the temperature were the most influential parameters with respect to the leaching process. The kinetic model best fit control by diffusion through the product layer. The activation energy of the dissolution celestite in nitric acid solutions was calculated to be 42.22 kJ/mol.

Background Foreign body (FB) ingestion is frequently encountered in all departments that treat children. FB may bring about significant anxiety for parents and physicians. The present study aims to determine the appropriate approach for FB ingestion in children. Methods The records of 1000 children with a history of FB ingestion between the years 2005 and 2017 were reviewed retrospectively in this study. Results Of 1000 children, 53.8% were male. The most common types of FBs were coins (35%). X-ray was negative in 49% of the patients, and 86% of these patients received no intervention. Of the 504 (51%) X-ray-positive patients, the oesophagus (68%) was the most common location. Life-threatening complications were tracheo-oesophageal fistula (1), Meckel's diverticulum perforation (1), and perforation due to rigid endoscopy (1). Conclusion We demonstrated that coins, which are the most commonly ingested FBs, have various types and sizes according to their countries of origin, and this affects spontaneous passage. We found that only 48% (quite low compared to the literature) of the coins passed spontaneously. In asymptomatic patients with a gastric button battery, we suggest a "watchful waiting" approach. The patients should be observed and managed at home. In our study, we found that 85% of the button batteries that reached the stomach passed spontaneously.

Lichens are very useful for monitoring of the radionuclide deposition because having a high efficiency capturing the radionuclides from the atmospheric fallout. In the present work, 210Po and 210Pb deposition in some lichen species were determined using an alpha spectrometer. Different lichens were collected around Demirci-Manisa and investigated their uses as biomonitor for 210Po and 210Pb deposition. The highest activity concentrations for 210Po and 210Pb were detected in Neofuscelia pulla (898 Bq kg−1 and 1207 Bq kg−1, respectively). The mean activities in the lichen species ranged from 164 to 584 Bq kg−1 for 210Po and from 175 to 671 Bq kg−1 for 210Pb. The activity ratios for 210Po/210Pb ranged from 0.75 to 1.57. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.

Pediatric experience with biliary tract injuries (BTI) is limited and mostly consists of case presentations. The purpose of this study is to evaluate clinical and radiological findings of possible BTI, treatment strategies, and results. The records of nine patients with the diagnosis of BTI between July 2009 and November 2017 were reviewed retrospectively. There were seven boys and two girls (mean 8.05 ± 4.39 years). The mechanisms were motor vehicle occupant, fall, crush and gunshot wound. Hepatic laceration routes that extended into the porta hepatis and contracted the gall bladder were demonstrated on computerized tomography (CT). Bile duct injury was diagnosed with bile leakage from the thoracic tube (n = 2), from the abdominal drain (n = 2) and by paracentesis (n = 5). Extrahepatic (n = 8) and intrahepatic (n = 1) bile duct injuries were diagnosed by cholangiography. Endoscopic retrograde cholangiography, sphincterotomy, and stent placement were successfully completed in five patients. Peritoneal drainage stopped after 3–17 days of procedure in four patients. The fifth patient was operated with the diagnosis of cystic duct avulsion. Cholecystectomies, primary repair of laceration, cystic duct ligation, and Roux-en-Y hepatoportoenterostomy were performed in the remaining four patients. All patients presented with clinically normal findings, normal liver functions, and normal ultrasonographic findings in the follow-up period. The presentation of the parenchymal injury extending to the porta hepatis with contracted gall bladder on CT and diffuse homogenous abdominal fluid should be considered as signs of BTI. We suggest a multi-disciplinary approach for the diagnosis and treatment of BTIs. Surgery may be indicated according to the patient’s clinical condition, radiological findings and failure of non-operative treatment.

Ureteroinguinal herniation is a rare event, usually diagnosed during the surgical repair of inguinal hernias and most reported cases have occurred in obese men during the fifth and sixth decades of life. Here, we describe the first case of unilateral renal and spermatic cord agenesis accompanying to the ureteral inguinal herniation in an infant.

Objective: Female congenital genital tract anomalies may appear with quite confusing and deceptive complications. This study aims to evaluate the difficulties in diagnosis and treatment of female congenital genital tract anomalies that frequently present with complications. Summary: During a 10-year period, we evaluated 20 female patients with congenital genital tract anomalies aged between 3 days and 16 years. All patients were retrospectively analyzed in terms of the results of diagnostic studies, surgical intervention, and treatment. Methods: Ultrasonography and magnetic resonance imaging revealed hydromucocolpos or hematocolpometra, imperforate hymen, distal vaginal atresia, didelphys uterus, an obstructed right hemivagina, uterovaginal atresia, a unicornuate uterus with a noncommunicating rudimentary horn, a vesicovaginal fistula, a utero-rectal fistula, intraabdominal collection, and a vaginal calculus. Results: Two patients had Mayer-Rokitansky-Küster-Hauser syndrome and 6 patients had obstructed hemivagina and ipsilateral renal anomaly syndrome. Definitive surgical interventions were hymenotomy, vaginal pull-through, vaginovaginostomy, and vesicovaginal fistula repair using a transvesical approach. In conclusion, female congenital genital tract anomalies may appear with a wide range of complications. Conclusions: There is a potential to do significant harm, if the patient's anatomic problems are not understood using detailed imaging. Revealing the anatomy completely and defining the complications that have already developed are critical to tailor the optimal treatment strategies and surgical approaches.
