Severe ovarian dysgenesis and enlarged dysplastic kidneys in two siblings with normal karyotypes.

Objective: To report a rare case of two normally karyotyped 46,XX siblings with severe ovarian dysgenesis and enlarged dysplastic kidneys.

Design: Case report. Rabin Medical Center, a major tertiary university-affiliated care and referral facility.

[Epulis during pregnancy].

Epulis is a hyperplastic lesion, which originates from the buccal mucosa and mainly from gingival tissues. It is characterised by several histologic types, of which the prevalent type during pregnancy is the granulomatous type, which is composed mainly of capillary vessels and endothelial proliferation. This lesion is referred to as "pregnancy tumor".

Preliminary studies on apoptosis in human fetal ovaries.

Objective: To evaluate if apoptosis occurs in human germ cells between 19 and 33 gestational weeks (GW).

Design: Human fetal ovaries were obtained from aborted fetuses aged 19-33 GW.

Setting: Rabin Medical Center, a major tertiary care and referral center.

Tc99m macroaggregated albumin cisternography for the detection of persistent cerebrospinal fluid (CSF) leak in an animal model.

The present study describes a new in vivo animal model that enables the detection of cerebrospinal fluid (CSF) leakage after dural injury. A polyethylene catheter (PE 10) was inserted into the subarachnoid space in the lumbar area by a simple surgical procedure and a radioactive isotope Tc99m Macroaggregated Albumin (Tc99m MAA) was injected into the CSF. In the experimental group, a standardised dural puncture was performed in the cervical area.
