Suprasellar arachnoidal cyst as a cause of precocious puberty--report of three patients and literature overview.

The authors present three boys--3 years old, 5.8 years old and 10.4 years old--who were diagnosed with isosexual precocious puberty (IPP) triggered by a rare developmental disorder of suprasellar arachnoid cyst (SAC) accompanied by corpus callosum and fornix dysgenesis as well as anterior commissura magna agenesis (patient 1) and empty sella (patients 2, 3). The reason for diagnostic management recommendation was a rapid progression of IPP signs over one year (patients 1, 2) or 6 months (patient 3) prior to hospitalization, these signs having been present but less intense since infancy (patient 1), 4th year of life (patient 2) and approximately 8 years of age (patient 3). Neurological signs (spastic paresis in patient 1, postural tremor in patient 2 and head bobbing and behavioral changes in patient 3), as well as slowly progressing increased head circumference were observed since neonatal period (patient 1), 1 year old (patient 2) and approximately 4 years old (patient 3). None of the patients manifested hypophyseal-hypothalamic axis dysfunction other than IPP prior to and after surgical management. Shunt implantation resulted in gradual resolution of neurological signs in all patients and in patient 3 also in partial normalization of serum testosterone levels and growth rate. Regression of IPP in patients 1 and 2 was achieved by administration of a long-acting GnRH analogue. Our observations are in accord with data reported by other investigators and confirm the often slow, insidious development of subsequent SAC signs, the type and intensity of which differ from patient to patient. We suggest that some of the neuroanatomical anomalies coexisting with SAC may have a common genesis, or they could under certain conditions be an additional trigger for IPP and possibly other hypothalamopituitary dysfunction.

Two siblings with unbalanced t(10;21) translocations and non-neuropathic neuropathic bladder.

We describe an unusual case of two siblings, aged 5 years and 5 months, with an unbalanced t(10;21) translocation and concomitant non-neuropathic neuropathic bladder abnormalities, whose father was a known balanced carrier of the translocation, t(10;21). Postnatally both siblings had normal spine and neurological examination. However, ultrasound scans and micturition cystourethrograms revealed grossly distended non-neuropathic neuropathic bladder. In both siblings, the bladder abnormalities responded to clean intermittent catheterisation. On follow-up, dimercaptosuccinic acid scans for both siblings showed equal split function with no scarring.

Neonatal obstructed Treitz's hernia with abdominal cocoon simulating volvulus neonatorum.

A case of congenital obstructed Treitz's hernia presenting with bilious vomiting in a newborn baby girl has been presented. Internal herniation of contents within a peritoneal sac of the right paramesocolic hernia formed abdominal cocoon which simulated volvulus neonatorum. Plain radiographs and contrast studies were helpful in defining the nature and extent of the lesion. The patient underwent exploratory laparotomy, reduction of small bowel contents from the hernial sac forming an abdominal cocoon, Ladd's procedure to correct associated midgut malrotation with incidental appendicectomy uneventfully and recovered well.
