Objective To study causes of deterioration of sudden mydriasis in craniocerebral trauma patients with normal intracranial pressure and verify the efficiency of specific treatments.Methods A retrospective analysis was performed on causes of four cases of accidental mydriasis in normal intracranial pressure among 473 cases of craniocerebral trauma treated from June 2008 to March 2012.Changes of patients' condition and monitoring indices were observed after specific treatments.Results Abnormal mydriasis with synchronously normal intracranial pressure was largely due to sufficient decompression after a certain period of intracranial hypertension and persistence of brain perfusion pressure to more than 110 mm Hg or due to high cerebral perfusion pressure caused by redundant drainage of cerebrospinal fluid or low intracranial pressure (＜ 10 mm Hg),together with factors like low plasma osmotic pressure and carbon dioxide accumulation.The study showed that the intracranial pressure was maintained normal,that the brain swelling took a turn for better,that medical condition were stabilized and that pupil returned to normal in the four cases after treatment with specific protocol.GOS was four points in three cases and five points in one during follow-up at six months postoperatively.Conclusion Incidence of mydriasis with normal intracranial pressure in craniocerebral trauma patients can be efficiently declined through reduction of peripheral blood pressure,perfusion pressure controlling,hypertonic remedy maintenance and brain edema relief.

Objective To improve treatment success rate and prognosis for patients with bifrontal contusions by intracranial pressure monitoring.Methods A retrospective analysis was conducted on 79 cases of bifrontal contusions admitted between October 2004 and April 2012.The patients were divided into intracranial pressure monitoring group (n =40) and group without intracranial pressure monitoring (n =39),according to the treatments.Significance of high coronary craniotomy timing,surgical strategy and intracranial pressure monitoring in the diagnosis,treatment and prognosis was analyzed.Results The intracranial pressure monitoring group showed a significantly shorter period concerning osmotic dehydration [(14.24 ± 7.93) days vs (21.61 ± 11.97)days,P＜0.01],ICU stay [(14.38 ±7.56)days vs (24.71-± 17.94)days,P＜0.01] and total hospital stay [(17.20 ±8.09)days vs (33.92 ± 21.70)days,P＜0.01] as well as a better GOS [(4.15 ± 1.22) points vs (3.69 ± 1.56) points,P ＜ 0.05],as compared with group without intracranial pressure monitoring.Conclusions Craniotomy,especially decompressive craniectomy,is one of the most important treatment means to control cranial pressure and ensure cerebral perfusion pressure in patients with bifrontal contusions (in particular the moderate and severe ones).Besides,intracranial pressure monitoring is conducive to selection of surgery timing and is instructive to combined treatment,such as osmotherapy,intracranial pressure controlling and assurance of cerebral perfusion pressure.

OBJECTIVETo develop and test a scoring system to predict the risks of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy(PD).

METHODSClinic data and postoperative complications of the 445 consecutive patients who underwent a PD procedure between January 2008 and April 2015 in Peking University First Hospital were retrospectively collected and analyzed.The patients were randomly selected to modelling and validation sets at a ratio of 3∶1, respectively.The patient data were subjected to univariate and multivariate analysis in the modelling set of patients.A score predictive of POPF was designed and tested in the validation set.

RESULTSPOPF occurred in 88 of 334 patients(26.4%) in the modelling set.The multivariate analysis showed that body mass index (BMI, P<0.01) and pancreatic duct width(P=0.001) are associated with POPF independently.A risk score to predict POPF was constructed based on these factors and successfully tested.The area under the receiver operating characteristic curve were 0.829(95% CI: 0.777-0.881) on the modelling set and 0.885(95% CI: 0.825-0.945) on the validation set, respectively.

CONCLUSIONSBMI and pancreatic duct width were associated with POPF after PD. The preoperative assessment of a patient's risk for POPF is feasible.The present risk score is a valid tool to predict POPF in patients undergoing PD, to make the selection on anastomosis types, and to take precautions against POPF.

Parenting competence is a new index to evaluate the parents′ ability to take care of their children and it gradually becomes a new research focus in the field of nursing. It not only meets the demand for child care, but also significantly reduces the occurrence of various medical problems during perinatal period by improving parents′parenting competence so as to enhance the level of maternal and child health care. So this paper aims to state the factors of sense of competence and provide a reference for clinical nursing staff.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
