An Unusual First-Trimester Ultrasound Presentation of the Acrania-Anencephaly Sequence: The "Turkish Turban" Sign.

A previously unrecognized first-trimester presentation of the acrania-anencephaly sequence is described. Ultrasound features included a constriction ring around the external base of the developing skull and an enlarged globular head, resembling a Turkish turban, with large cystic spaces replacing the brain. This constellation of findings was noted in 3 first-trimester fetuses. In 2 of them, it was possible to identify the amniotic membrane attached to the constriction ring. One case presented with anencephaly and fetal demise at 16 weeks. The other 2 women terminated the pregnancies and aborted anencephalic fetuses. This subtype of the acrania-anencephaly sequence could represent an earlier segmental rupture of the amnion, which subsequently entraps the developing fetal skull.

Impact on hospital functions following the 2010 Chilean earthquake.

OBJECTIVE: The objective of this study was to assess the impact of the 2010 Chilean earthquake on hospital functions and services. Hospitals functioning in a post-disaster environment must provide emergency medical care related to the event, in addition to providing standard community health services. This study focused on damage to both structural and nonstructural components, as well as to utility services. METHODS: Site visits were made to every hospital in a single province (Bio-Bio). Engineers conducted damage assessments while interviews of hospital administrators were conducted. The survey was requested by the Chilean Ministry of Health (MOH) to assess the impact of the earthquake on hospital operations and facility responses to those effects. Other important regional and hospital data were gathered from hospital administrators and the MOH. RESULTS: Seven government hospitals were surveyed. All hospitals in the region lost communications, municipal electrical power and water for several days. All reported some physical damage although only one suffered significant structural damage. All lost some functional capacity as a result of the earthquake. The loss of telephones and cellular service was identified as the most difficult problem by administrators. An average of 3 physical areas per hospital lost some degree of functional capacity following the earthquake. CONCLUSION: Even in an earthquake-prone and very well-prepared country such as Chile hospital functions were widely disrupted by the event. The loss of hospital functions can occur even with minimal damage to the physical structure. The loss of communications can impede or halt response efforts at all levels. Hospitals should be prepared to self-sustain following a disaster for 2-3 days regardless of the level of structural damage. Understanding the details of these impacts is essential to hospital preparedness and plans for continuing services after a disaster.
