[Scrotal trauma in childhood].

Scrotal trauma has increase in frequency during recent years, largely as the result of sporting activities, physical aggressions and road accidents. Its importance lies in the likelihood of associated lesions of the testis and the spermatic cord. We report 41 cases of scrotal trauma. Thirty-seven cases were non-penetrating and four were penetrating (including a case of traumatic rupture of the testis). Nonsurgical treatment was applied in 30 cases (73.1%) and surgical treatment in 11 (26.8%). The diagnostic techniques employed included ultrasonography in 19 cases, gammagraphy in 10 cases, Doppler-effect ultrasonography in 2 cases and CAT in 2 cases. The decision to operate should be based on the clinical findings. Follow-up studies over 8-60 months were satisfactory in all cases, with no cases of testicular atrophy detected.

Measurement of colonic transit time in children.

Transit times through the whole colon and its segments were measured in 10 healthy children and 14 children suffering constipation secondary to myelomeningocele. The subjects ingested radio-opaque markers on three successive days, and on the fourth a plain abdominal roentgenogram was taken using fast film. In the healthy children, total colonic transit time (mean +/- SD) was 37.8 +/- 6.2 h, with segmental times of 10.8 +/- 3.5 h for the right colon, 12.2 +/- 2.7 h for the left, and 14.7 +/- 2.1 h for the rectosigmoid; upper normal limits of 17.8 h for the right colon, 17.6 h for the left, 19.1 h for the rectosigmoid, and 50.2 h for the total colonic transit time were established. In the constipated children, the total transit time was 59.9 +/- 5.4 h, with segmental times of 15.9 +/- 2.3 h for the right colon, 18.9 +/- 2.3 h for the left, and 25.0 +/- 2.6 h for the rectosigmoid. The technique described is simple, is easy to use in clinical practice, and involves a lower radiation dose than other methods. It may prove useful for measurement of colonic transit time in suitable patients.

[Evaluation of medical and surgical treatment of intestinal invagination in children].

Authors review 70 consecutive cases of intussusception treated from 1969 to 1984. Most patients (87.5%) were under one year, and male/female ratio was 2/1. Nutritional status was good as 75.7% were above 50 percentiles for age. There was a higher seasonal incidence in spring and summer. Most frequent presenting symptom were weeping/pain (87.1%), rectal bleeding (82.8%) and vomiting (78.5%). Typical symptomatology was present in only 48.5%. Plain X-ray of abdomen and ultrasonography are the best diagnostic aid (91.4% and 90%). Hydrostatic reduction was successful in 30.1% whereas 51 cases had to be operated with a resection rate of 27.5%. Half of the patients over two years had an organic leading point. Complications, 8.6% were related with age, clinical course and need for bowel resection.

[Osteosarcoma: 2d malignant tumor following treatment with radiotherapy].

The authors report a case of postirradiation osteosarcoma that appeared in a seven year old girl after having received radiation therapy for a soft tissue sarcoma. The latent period between the two malignancies was 5 and a half years and the apparently radiation-induced osteosarcoma developed within the radiation field of the primary tumor.
