ONE TEXT FIGURE AND THREE PLATES (NINE FIGURES)As is well known, the prepuce in the human penis is adherent to the glans at birth, a layer of stratified squamous epithelium being interposed, and shortly after birth these parts become separated so that the prepuce may be retracted.Failure of the prepuce to separate from the glans spontaneously o r neglect to separate the parts by artificial means results in phimosis or inability to retract the prepuce. Frequently, the customary retraction about the eighth day of infancy exposes irregularly distributed bleeding points, indicating incomplete separation.It is the purpose of this study to ascertain more definitely the nature of this cleaving process, the time of its onset, and the age when ultimate separation is completed.
LITERATURENumerous papers dealing primarily with certain other phases of the embryology of the human penis make only secondary reference to the mechanism of preputial separation. For the most part these observations are based on one or at best on few age periods only and usually refer to material before birth. In no instance is the process followed from beginning to end in a serial study.Bokai (1860) was the first to direct attention to the physiological adherence of the foreskin. Schweiger and Seidel (1866) gave the first description of the development of the
\s=b\Transillumination is shown to be an effective device in the early diagnosis of enlarging skull fractures in children.(Am J Dis Child 131: [889][890][891][892] 1977) Transi l l umi nati on has been em¬ ployed in the diagnosis of large meningeal cysts associated with en¬ larging skull fractures occurring in early childhood.11 We report the case of an infant with an enlarging skull fracture due to cerebral herniation alone in which transillumination as¬ sisted in the early diagnosis of the defect.
REPORT OF A CASEOur patient is an 8-month-old female infant who suffered a linear right parietal skull fracture at age 6 months in an auto¬ mobile accident. She was unconscious fol¬ lowing the accident and required resuscita¬ tion. Focal seizures of the left arm and leg were treated with intravenously adminis¬ tered diazepam. A left hemiplegia was then noted. The patient was hospitalized at From the
