First measurements of spin-dependent double-differential cross sections and the Gerasimov-Drell-Hearn Integrand from 3He(γ,n)pp at incident photon energies of 12.8 and 14.7 MeV.

The first measurement of the three-body photodisintegration of longitudinally polarized (3)He with a circularly polarized γ-ray beam was carried out at the High Intensity γ-ray Source facility located at Triangle Universities Nuclear Laboratory. The spin-dependent double-differential cross sections and the contributions from the three-body photodisintegration to the (3)He Gerasimov-Drell-Hearn integrand are presented and compared with state-of-the-art three-body calculations at the incident photon energies of 12.8 and 14.7 MeV. The data reveal the importance of including the Coulomb interaction between protons in three-body calculations.

Frontal sinus osteoma associated with cerebral abscess formation: a case report.

BACKGROUND: Osteomas of the paranasal sinuses rarely lead to intracranial manifestations. We present an unusual case of a frontal sinus osteoma leading to intracerebral abscess formation. CASE DESCRIPTION: A 51-year-old Hispanic man presented with increasing frontal headaches, new onset seizure, lethargy, global dysphasia, and unilateral hemiparesis. CSF studies demonstrated mild pleocytosis. Neuroradiological studies revealed an opacity filling the left frontal sinus, as well as a ring-enhancing mass with surrounding edema in the left frontal lobe. The patient was surgically treated with a left frontal osteoplastic craniotomy and removal of the abscess and bony mass. Intraoperative cultures were positive for Streptococcus pneumoniae. Pathology revealed bony tumor consistent with osteoma. The patient's neurological status improved to baseline after surgery. CONCLUSION: The frontal sinus osteoma was associated with rapid development of a frontal lobe abscess, requiring emergent surgical debridement. Although rare, intracerebral manifestations should be considered and expected as a cause of new neurological deficits in the presence of paranasal sinus osteoma.

The KEMH method for securing umbilical catheters.

A new method of fixation of umbilical catheters is described. This method utilizes a purse-string suture around the cord stump, which is then secured through the umbilical skin and fixed to the catheter with adhesive tape. This method avoids damage to the fragile skin, particularly of the preterm newborn, caused by the use of T piece strapping.

Maternal grieving response after perinatal death.

The nature and incidence of psychological and related physical disturbances were investigated in 110 mothers who had lost a child in the perinatal period. The mothers were interviewed six to 36 months after their loss. The demographic characteristics, hospital experiences, effects of bereavement and perceived social support system of the women were assessed. A pathological bereavement outcome, which was defined as a marked deterioration in health and evidence of increased social adjustment problems, was identified in 21% of the women. A pathological bereavement outcome was found to be related to two main factors--a reported crisis during pregnancy and the perceived support of the husband and/or family. Whether the mother saw but did not hold her baby was also a factor. These results suggest that the loss of a baby may have at least as severe an effect on a woman as the death of her husband. The implication of these findings is that women who are at risk of a pathological outcome of bereavement may be identified soon after their loss.
