Gamma-ray fast-timing coincidence measurements from the 18O+18O fusion-evaporation reaction using a mixed LaBr3-HPGe array

We report on a gamma-ray coincidence analysis using a mixed array of hyperpure germanium and cerium-doped lanthanum tri-bromide (LaBr3:Ce) scintillation detectors to study nuclear electromagnetic transition rates in the pico-to-nanosecond time regime in 33,34P and 33S following fusion-evaporation reactions between an 18O beam and an isotopically enriched 18O implanted tantalum target. Energies from decay gamma-rays associated with the reaction residues were measured in event-by-event coincidence mode, with the measured time difference information between the pairs of gamma-rays in each event also recorded using the ultra-fast coincidence timing technique. The experiment used the good full-energy peak resolution of the LaBr3:Ce detectors coupled with their excellent timing responses in order to determine the excited state lifetime associated with the lowest lying, cross-shell, Iπ=4- "intruder" state previously reported in the N=19 isotone 34P. The extracted lifetime is consistent with a mainly single-particle M2 multipolarity associated with a f7/2→d5/2 single particle transition.     

Hyperemesis gravidarum: current aspect

An advanced state of nausea and vomiting, which are common symptoms of early pregnancy, is known as hyperemesis gravidarum and may result in dehydration, ketonuria, catabolism and require hospitalisation. Aetiological factors include increased hCG and steroids, multiple pregnancy and vitamin deficiency. Differential diagnosis of nausea and vomiting should be made and supportive treatment as well as antiemetic therapy is recommended. This review discusses aetiology and management modalities of hyperemesis gravidarum including fluid therapy, antiemetics, vitamins, psychological support and non-pharmacological measures.     

Traumatic internal carotid artery dissection associated with playing soccer: a case report

Soccer, one of the most popular sports worldwide among young men, can result in a wide range of orthopedic injuries. Although vascular injuries such as dissection occur rarely, they can cause significant mortality if left undiagnosed. We report herein a 31-year-old male who suffered a large middle cerebral artery infarction due to traumatic internal carotid artery dissection after a ball struck his head and neck. He recovered with mild neurologic deficit after decompressive surgery.     

Masked urinary bladder injury with a bullet expulsed spontaneously during voiding

We report a case with gunshot to the pelvis. The injury site was the soft tissue between the rectum and urinary bladder. Several days later, the bullet was expulsed spontaneously during voiding. In the literature, only a few case reports have described spontaneous expulsion of an intravesical bullet. A 19-year-old male was wounded on the left hip by gunshot. Radiographic examinations showed a bullet in the pelvis, which was localized in the soft tissue between the rectum and urinary bladder, with no accompanying visceral injury on abdominopelvic computerized tomography. Macroscopic hematuria was noticed after urethral catheterization. Rectosigmoidoscopy and retrograde cystoscopic examinations were both negative. The patient was monitored closely and treated conservatively with no surgical intervention. The urinary catheter was removed on the fifth postoperative day, and the bullet was expulsed spontaneously via the urethra during normal voiding three hours after catheter removal. Thereafter, a retrograde urethrography was performed, which showed no evidence of urinary tract or bladder injury.
