“…Recent reports found that teratomas were more common than endodermal sinus tumorsin children. The gonadal stromal tumors are usually benign, there has been the very rare case of malignant gonadal stromal tumor 4,5,6 . Almost all types of testicular tumors can be seen in the new-born.…”

“…Until recent years, the majority of these tumors have been known to be malignant but now we know that testicular tumors are most commonly benign than malign. However, the proportion of malignant tumors in older children (over the age of 13) increased 4,5,6 . Physical Examination: Most children with testicular tumors present with an asymptomatic mass or scrotal swelling.…”

ÖzetÇocuklarda testis tümörleri nadirdir. Teratomlar ve yolk sac tümörleri çocuklarda en sık görülen testis tümörleridir. Testis tümörleri sıklıkla ağrısızdır. Bu yanlışlıkla hidrosel tanısına neden olur. Tanıda tümör belirteçleri ve ultrasonografi kullanılmaktadır. Benign tümörler malign tümörlerden daha sık görülmektedir. Testis tümörlerin temel tedavisi inguinal orşiyektomidir.

“…Yolk sac tumors (endodermal sinus tumors) and teratomas are the most common primary pre-pubertal testicular tumors. 5 All tumors of the bladder and urethra is rare in children; benign tumors are even more infrequent. Benign tumors in children described in case reports include polyps, papilloma, hemangioma etc.…”

Objective: To document general baseline data on the patterns of childhood genitourinary tumors. Design, Setting and Participants: This is a retrospective analysis of 28 cases of pediatric genitourinary tumors (Age group 0-12 years) in surgical pathology in a tertiary care hospital encountered over a period of 5 years. Results: In the genitourinary system tumors of the kidney, bladder, prostate, testis, and adrenal were included. A total of 3149 pediatric surgical specimen presented over a five years. Of this, 28 were diagnosed with genitourinary tumors. In the renal tumors only Wilm's tumors (WTs) (9 cases) was seen, with classical triphasic tumors were more common. The mean age of presentation is 3 year with commonest age group of presentation (8 cases out of 9) in the age group 1-5 years. Three of them had showed unfavorable histology. Among the gonadal germ cell tumors, there were noted four mature teratoma, one immature teratoma, two yolk sac tumors of ovary & one yolk sac tumour in testis was seen. In the adrenal gland, adrenal medullary tumors were more common than adrenal cortex with neuroblastoma (4 of 10 cases) as common individual tumor. Conclusion: Different types of genitourinary tumors seen in the childhood. A high index of suspicion should be maintained with an aim of surgical treatment to avoid the poor management. Histological type is important for understanding etiology and progression of disease. The likelihood of a given type of tumor being present in a particular age or sex group or particular site may heighten the index of suspicion and ultimately influences etiology, biology, and natural history, relative incidence and distribution frequency, clinical presentation and manifestations, and response to therapy and outcome."

A Sedimentological Model to Characterize Braided River Deposits for Hydrogeological Applications

Braided river deposits form important aquifers in many parts of the world, and their heterogeneity strongly influences groundwater flow and mass transport processes. To accurately characterize these coarse gravelly aquifers, it is important to understand the erosional and depositional processes that form these sediments. Moreover, it is important to evaluate the relative importance of various parameters that determine the preservation potential of different depositional elements over geological time scales. These objectives may be achieved by developing techniques that allow for the integration of different quality data into quantitative models. Information concerning sedimentary textures and the spatial continuity of sedimentary structures in braided river deposits, inherent in depositional facies descriptions, allows the spatial variability of hydrogeological properties (e.g. hydraulic conductivity and porosity) to be predicted. Depositional elements in gravel deposits can contain a restricted range of textures, which form a limited number of sedimentary structures. These depositional elements are bounded by erosional and/or lithological surfaces. The frequency, size and shape of different elements in a sedimentary sequence depend on several factors, including aggradation rate, channel belt mobility on the kilometre scale, gravel-sheet/scour activity at the scale of hundreds of metres and topographic position of the different elements within an evolving system. Preserved shape and size of the elements affect the correlation lengths and the standard deviations of the aquifer properties, such as hydraulic conductivity and porosity.Different quality data sets that may be used in characterizing braided river deposits can be recognized in outcrop, boreholes and on ground-penetrating radar (GPR) sections. This paper proposes a means of integrating outcrop, borehole and GPR data into a stochastic framework of sedimentary structures and the distribution of hydraulic aquifer properties. Data integration results in variable degrees of uncertainty when assigning values to hydraulic properties and characterizing the geometry of sedimentary structures. An application of this approach is illustrated using a data set (400 m × 550 m) from the northeastern part of Switzerland at the confluence of the Rhine and Wiese rivers. The data set includes drill-core data from five boreholes and 14 GPR sections with a total length of 3040 m. The results of the variogram analysis provide the orientation of sedimentary structure types representing the main flow direction of the River Rhine in the lower part of the aquifer, and of the River Wiese in the upper part. The analysis also results in large ranges of spatial correlation, ranging from a few metres up to tens of metres for the different sedimentary structure types.
