of choice is surgery. The girl recovered completely after extirpation of a cherrysized insuloma situated between pancreatic body and tail. The authors point out the importance of visceral arteriography in early diagnosis of islet cell tumors in children to permit efficient therapy before irreversible hypoglycemic brain damage has occurred.-C.

GENITOURINARY TRACT
Lower Urinary Obstruction in Infancy. S. Tsingoglou and J. A. S. DEc/pon. Arch. Dis. Child. 47:216-217 (April), 1972. A total of 165 infants admitted under the care of D. I. Williams at the Hosoital for Sick Children, London, in the period 19591970 are reviewed. This series consists of 130 males and 35 females. Sixty-eight infants were admitted in their first month of life, and thereafter there was a steady decrease in the number of infants. The most common lesions were posterior urethral valves in 91 male infants and ectopic ureterocele in 34 infants (seven male, 27 female). The presentation and signs are discussed. The overall mortality was 30 deaths, 22 among the 68 infants admitted in the first month of life. Of the 91 patients admitted with urethral valves, 21 died. -D. G. .Young
count, colony count, and germ identification. As urine taken by bladder puncture normally is sterile, any germ presence in PS was considered pathological. The UT1 diagnosis was confirmed by pathological PS in only 22 of 48 cases with contaminated BS, the identity of germs in both BS and PS concurring in 22 of 23 cases. Since WBC counts did not regularly correspond to germ presence, Ieucocyturla has been concluded as by no means a reliable sign of UTI. Considering the simplicity, the efficiency, and the very small risks of the method, in addition to the convincing results of their studv, the authors recommend the suprapubic bladder puncture as the most reliable procedure of diagnosing UTl in infants at present. -C. Bretscher Gonadal Dysgenesis and Chromosome Mosaicism. C. J. Dewhurst. Hosp. Med. 6: 607-612 (December), 1971. Atypical examples of gonadal dysgenesis associated with chromosome mosaicism and cytogenetic considerations of these abnormalitles are lucidly explained. The endless karyotype possibilities, percentage penetration of mosaicism with the embryo and its gonad, explain the development of secondary sexual characteristics. Buccal smear, chromosome studies, gonadal biopsy, and surgical ablation of streak testes are included as relevant to the management. No surgical details are given.-M. R. Logk
Comparative Bacteriological Study of Conventionally Collected Urine Specimens (Bag/Clean Catch) and Specimens Obtained by Bladder Puncture in Young Children. G. E. Moretti and E. Gautier. Helv. Paediat. Acta 26:616-623 (December), 1971.

The importance of reliable urinary tract infection (DTI) diagnosis in young children and former studies on urine-collecting methods have led the authors to compare bacteriological results in urine specimens obtained in 28 boys and 15 girls (mostly below 2 yr of age) by collection of spontaneously voided urine in sterile plastic bags (BS) and by aspiration of urine by supranubic puncture into sterile syringes according to Nelsons’ technique (PS). All 160 BS and 33 PS were examined by WBC
This is a compilation of basic articles, written by men reknowned in their field, related to orthopedic surgical problems with children. A collection of articles on scoliosis, including writings by Walter P. Blount, John H. Moe, Paul R. Harrington, Jacqueline Perry, John E. Hall, and others, serves as a thorough review of the techniques that these individuals have made famous. The volume also features review articles by including “Cerebral Palsy Knee others, Problems” by Henry H. Banks, “Congenital
