Abstract: The authors report the results of a long-term follow-up study of 130 patients with 161 unruptured intracranial saccular aneurysms. Their findings suggest that unruptured saccular aneurysms less than 10 mm in diameter have a very low probability of subsequent rupture. The mean diameter of the aneurysms that subsequently ruptured was 21.3 mm, compared with a diameter of 7.5 mm for aneurysms defined after rupture at the same institution. Part of the explanation for this discrepancy may be that the size of the filling compartment of the aneurysm decreases after rupture. There is also evidence from the present study that intracranial saccular aneurysms develop with increasing age of the patient and stabilize over a relatively short period, if they do not initially rupture, and that the likelihood of subsequent rupture decreases considerably if the initial stabilized size is less than 10 mm in diameter. Consequently, the critical size for aneurysm rupture is likely to be smaller if rupture occurs at the time of or soon after aneurysm formation. There seems to be a substantial difference in potential for growth and rupture between previously ruptured and unruptured aneurysms.
answer:
The significance of unruptured intracranial saccular aneurysms.

Abstract: Cannulation of the fimbriated end of the fallopian tube during gamete intrafallopian tube transfer (GIFT) may be at times extremely difficult and even require minilaparotomy. An ideal laparoscopic GIFT catheter should be flexible and stirrable, have a small diameter, and yet be sturdy enough to enable its manipulation. Such a catheter was developed in collaboration with Cook Ob/Gyne, a Division of Cook Inc., Indiana, with primary emphasis on easy laparoscopic manipulation. Its use in eight attempts of GIFT resulted in three pregnancies (37%).
answer:
A new stirrable catheter for gamete intrafallopian tube transfer (GIFT).

Abstract: We studied the value of transcutaneous carbon dioxide (PtcCO2) monitoring during neonatal transport. Thirty-two neonates with respiratory distress were alternately enrolled in an experimental group (results of PtcO2 and PtcCO2 available for clinical management) and a control group (results of only PtcO2 available). Although differences were not significant, infants in the experimental group had more changes in the intermittent mandatory ventilation (IMV) settings during transport, and more such infants arrived at the receiving hospital with acceptable pH and PCO2 values. On arrival at the receiving hospital, two patients in the control group had acidosis and hypercarbia and were placed on IMV immediately on arrival. No such patients were encountered in the experimental group. For patients needing IMV during transport, the percentage of study time spent with PtcCO2 measurements in the normal range (35 to 45 torr) was greater for the experimental group (p less than .02). Continuous PtcCO2 monitoring during transport offers the opportunity to further decrease the risks of transporting a critically ill neonate.
answer:
Transcutaneous carbon dioxide monitoring during neonatal transport.
