Abdominal distension in Kaufman-McKusick syndrome.

A female infant with Kaufman-McKusick syndrome redeveloped respiratory distress and abdominal distention at 5 weeks of age. Ultrasonography demonstrated recurrence of peritoneal cysts and hydrometrocolpos. It is postulated that refluxing vaginal secretions may contribute to the abdominal distention seen in many infants with Kaufman-McKusick syndrome.

Percutaneous drainage of iliopsoas abscess in Crohn's disease.

Iliopsoas abscess is a rare but serious complication of Crohn's disease. Initial treatment by surgical drainage of the abscess alone or in combination with bowel resection has been recommended. Percutaneous catheter abscess drainage (PAD) has not been described. We report 3 patients with this uncommon complication of Crohn's disease in whom PAD was attempted. It was successful in 2 cases but failed in 1, who went on to have the abscess drained surgically. We suggest that PAD can be a useful initial treatment to improve the patient's condition prior to definitive surgical resection.

Septal veins: a normal finding on neonatal cranial sonography.

The appearance of normal septal veins on cranial sonography is described. Septal veins are part of the deep cerebral (galenic) venous system. Improved technology allows these structures to be identified as they course in the walls of the cavity of the septum pellucidum (cavum septi pellucidi). These veins are normal structures that should not be misinterpreted as pathologic ventricular septations, calcifications, or evidence of prior intracranial hemorrhage.

Prenatal and immediate postnatal ultrasonographic diagnosis of ureterocele.

We report three patients in whom hydronephrosis was diagnosed by ultrasonography in utero. In two fetuses, ureteroceles were detected prenatally and these proved to be the cause of obstruction. In the third, bilateral simple ureteroceles were discovered immediately after birth. In the last patient, failure to see ureteroceles in utero may have been related to the phenomenon of ureterocele eversion and prolapse into the ureter. Ultrasonographers should be aware of this prolapse phenomenon as a potential pitfall for both the in utero and postpartum diagnosis of ureterocele.

Conjoined twins. Antenatal ultrasound diagnosis and a review of the literature.

Three sets of conjoined twins recently diagnosed by us in the antenatal period are presented. From these cases and a review of the literature we present the ultrasound diagnostic features of the various forms of this rare condition. We discuss the importance of associated anomalies and shared organs with their relevance to subsequent antenatal management and delivery. The importance of excluding this condition whenever twins are diagnosed on ultrasound is stressed.

Results and costs of investigating newly detected hypertensive patients.

1. Eighty unselected hypertensive subjects were investigated at a cost of $78.00 per patient, in a short out-patient study programme. Seven (9%) were found to have a cause for their hypertension; incidental abnormalities were found in twenty-two (28%). 2. The combination of clinical selection and planned out-patient investigation should detect all patients with secondary hypertension.

Gonadoblastoid testicular dysplasia in Walker-Warburg syndrome.

Two male fetuses (18 and 22 weeks gestation) and a 3-month-old male infant (full sibling of the younger fetus) who were diagnosed with Walker-Warburg syndrome (WWS) on the basis of neuropathologic autopsy findings in brain, eyes, and muscle also had micro-orchia and, microscopically, diffuse gonadoblastoid dysplasia in the testes. Both fetuses also had a miniature left ureter and cystic dysplastic left kidney. Testes from control fetuses of 17-24 weeks gestation with normal karyotype and no central nervous system abnormalities (group A, n = 50), a variety of central nervous system abnormalities (group B, n = 50), or an autosomal aneuploidy syndrome with or without central nervous system abnormalities (group C, n = 30) had no diffuse dysplasia, although a single gonadoblastoid seminiferous tubular profile was present in three controls. Testicular morphology was normal in older fetuses and infants with a wide variety of central nervous system malformations (group D, n = 50). We found no evidence of hypogonadotrophic hypogonadism in the three WWS cases to account for the small penis and incompletely descended testes commonly reported in this condition. We concluded that the apparent specificity of the gonadoblastoid testicular dysplasia to WWS suggests that the gene defect directly affects testicular development.
