Summary The authors describe in this paper the occurrence of five cases of dioctophymiasis in Maned wolves Chrysocyon brachyurus belonging to Sao Paulo Zoo. Clinical symptoms are described and the lesions found at post‐mortem examination are noted. Agreeing with the veterinary literature on the subject, they also verify that the infestation is in the right kidney. Finally, they show the possibility of diagnosis by radiography and treatment by nephrectomy.

The aim of the ultrasound (US) screening program was to detect neoplastic lesions in children, together with other pathologies of the developmental age in the area of the neck, abdomen, female pelvis, and scrotum in boys.US screening scans, including cervical, abdominal, pelvical, and scrotal US, were performed in the population of asymptomatic children aged from 9 months to 6 years. The children were scanned in Mobile Pediatric US Unit, consisting of 2 independent consulting rooms.The scans of 14,324 children were analyzed, 7247 boys and 7077 girls. Totally 42,538 US examinations were performed, including 14,187 cervical scans, 14,259 abdominal scans, 6942 female pelvical scans, and 7150 scrotal scans. Totally 5426 abnormalities were detected, which represent 12.7% of all examinations and 30% of patients. Three tumors were recognized, which are renal malignant tumor diagnosed as Wilms tumor, neurogenic tumor of the rib, and teratoma of the testis.US screening in pediatric population can be used to reveal lesions inaccessible to clinical examination, like tumors or other pathologies of developmental age before the onset of clinical symptoms. Due to the large number of detected abnormalities it should be recommended to the whole population of certain age.

IntroductionUltrasonography plays an important role in evaluation of many diseases in pediatric population. The noninvasiveness of the method allows to its wide use in children. It is a first-line diagnostic test for detecting lymphadenopathy, benign and malignant abnormalities of the thyroid gland, abdominal structures or testes in boys. The Ultrasound Screening Program “No to Cancer in Children” was introduced to detect neoplastic lesions and possible developmental disorders in children with no symptoms to allow early diagnosis.Material and methodsThe children were scanned in special mobile ambulance - Ronald McDonald Care Mobile, equipped with two high-tech ultrasound devices. Ultrasound scans, including cervical, abdominal, pelvical and scrotal ultrasound were performed in population of asymptomatic children. In the years 2006-2019, 67.594 children, 34.892 boys and 32.702 girls aged from 9 months to 6 years were examined.ResultsTotally, 18.544 various abnormalities were detected. In case of the neck they were found in 7542 children, which represent nearly 11.2% of all patients. Changes in abdominal ultrasound were found in 4.496 cases (6.65%). Abnormalities of the male reproductive system were detected in 6.474 boys (18.5%). Twelve tumors were detected.ConclusionsScreening has proved to be very useful for the early identification cancerous as well as precancerous lesions. It is also worth continuing for a reason of effective detection of other childhood anomalies.
