Intracranial infections are one of the most common neurological diseases in children and are associated with high mortality and morbidity. Intracranial hypertension and hydrocephalus are the common, fatal complications of intracranial infections, so early diagnosis and timely treatment are the keys to saving patients' lives and reducing neurological sequelae. This paper introduces the progress in the etiology, diagnosis, and treatment of intracranial hypertension and hydrocephalus in children with intracranial infections.

OBJECTIVE: To investigate the factors for hydrocephalus secondary to severe traumatic brain injury after surgery, and to explore a new theory and guideline for clinical early prevention and treatment for hydrocephalus.
 METHODS: The clinical data regarding 107 patients with severe traumatic brain injury, who were admitted to our hospital from June 2010 to June 2013, were analyzed. Logistic multi-factor regression was used to analyze the different factors including ages, gender, the Glasgow coma scale (GCS) score before or after surgery, the situation of ventricular system bleeding secondary to surgery, the situation of midbrain aqueduct and ambient cistern before or after surgery, the relationship between early lumbar puncture and the hydrocephalus. The risk and protective factors for postoperative hydrocephalus were discussed.
 RESULTS: The results showed that patients with low GCS score in pre/postoperative (OR=0.099, 95%CI: 0.028-0.350)/(OR=0.088, 95%CI: 0.012-0.649), ventricular system bleeding in postoperative (OR=0.168, 95%CI: 0.029-0.979) and dim CT image for midbrain aqueduct and ambient cistern (OR=0.134, 95%CI: 0.038-0.473)/(OR=0.221, 95%CI: 0.055-0.882) are risk factors. Whereas lumbar puncture (OR=75.885, 95%CI: 9.612-599.122) is a protective factor for postoperative hydrocephalus in STBI patients. The secondary hydrocephalus was mainly occurred in 2 weeks and 2 weeks to 3 months after operation. The incidence of the control group that occurred secondary hydrocephalus is higher than that of the lumbar puncture group (P<0.05). The secondary hydrocephalus were mainly occurred in 2 weeks and 2 weeks to 3 months after operation, with no statistical significance between the 2 groups after 3 months of operation (P>0.05).
 CONCLUSION For patients with stable vital signs, early lumbar puncture could significantly reduce the incidence of secondary hydrocephalus in acute and subacute stage after severe traumatic brain injury.

OBJECTIVETo investigate risk factors for the occurrence of shunt-dependent hydrocephalus in patients with aneurysmal subarachnoid hemorrhage (aSAH).

METHODSA cohort of 136 consecutive patients who were treated for ruptured aneurysms within 72 h after onset of aSAH from January 2011 to January 2013 were retrospectively analyzed. Lumbar drainage was performed during the surgery in all patients. The risk factors of shunt-dependent hydrocephalus were analyzed.

RESULTSOf 136 patients, 23 (16.91%) underwent shunt operation to treat shunt-dependent hydrocephalus. Univariate analysis showed that Hunt-Hess grade at admission (P<0.01), Fisher grade (P<0.01), the presence of intraventricular hemorrhage (P<0.01), location of ruptured aneurysm (P=0.001), and the average daily volume of cerebrospinal fluid drainage (CSF) (P=0.047) were associated with shunt-dependent hydrocephalus.

CONCLUSIONThe aSAH patients with poor Hunt-Hess grade at admission, high Fisher grade, the presence of intraventricular hemorrhage, ruptured aneurysm in posterior circulation, and abnormal average daily volume of CSF are more likely to develop shunt-depended hydrocephalus.

OBJECTIVETo study the role of transforming growth factor-β1 (TGF-β1) levels and other risk factors in the occurrence of chronic hydrocephalus after aneurysmal subarachnoid hemorrhage (aSAH).

METHODSPatients treated for aSAH in our hospital between January, 2007 and June, 2012 were divided into non-hydrocephalus group and hydrocephalus group. TGF-β1 levels in the cerebrospinal fluid (CSF) were compared between the two groups at different time points. A retrospective analysis was conducted to identify the potential risk factors for chronic hydrocephalus, which were subsequently confirmed by Logistic regression analysis.

RESULTSOf the 129 patients enrolled, 16 (12.4%) developed chronic hydrocephalic with an average diagnosis time of 31.6∓17.0 days. In patients with chronic hydrocephalus, TGF-β1 level in the CSF increased significantly on the 13th day following aSAH (P<0.05). Retrospective analysis showed that the patients with hydrocephalus and those without had significant differences in history of hypertension, times of SAH, Hunt-Hess classification, ventricular expansion, aneurysm position, Fisher classification, ventricular hemorrhage score and intracranial infections (P<0.05). Logistic regression analysis identified ventricular expansion, aneurysm position, Fisher classification, ventricular hemorrhage score and postoperative intracranial infections as significant risk factors for the occurrence of chronic hydrocephalus (P<0.05).

CONCLUSIONSIn adult patients with aSAH, the risk factors for chronic hydrocephalus include ventricular expansion, aneurysm position, Fisher classification, ventricular hemorrhage score and postoperative intracranial infections. These risk factors can have greater clinical value than TGF-β1 levels in the CSF in predicting the occurrence of chronic hydrocephalus following aSAH.

OBJECTIVETo explore the management of obstructive hydrocephalus caused by posterior fossa tumors before tumor resection in children.

METHODSThe clinical data were reviewed of 162 pediatric patients of posterior fossa tumors with obstructive hydrocephalus undergoing surgical tumor removal between January 2008 and June 2012. Ninety children received preoperative Ommaya external drainage (group A) and 72 underwent preoperative ventriculo-peritoneal shunting (V-Ps) (group B). The therapeutic effects were evaluated and compared between the two groups.

RESULTSPostoperative complications found in a total of 67 cases including infection (27), shunt blockage (19), subdural hematoma or effusion (16), ventricle fissure syndrome (5), and tumor hernia (4). Significant differences were found in the incidences of shunt blockage (P=0.047) and subdural hematoma or effusion (P=0.039) but not in the incidences of intracranial infection (P=0.478) or tumor hernia (P=0.462) between the two groups.

CONCLUSIONOmmaya reservoir can produce good results through simple surgical procedures for treatment of acute hydrocephalus in children with posterior fossa tumors and is associated less trauma and complications.

OBJECTIVETo observe the therapeutic effect of Ommaya reservoir implantation on hydrocephalus in premature infants following intraventricular hemorrhage (IVH) and to investigate factors influencing the therapeutic effect.

METHODSAn ambispective cohort study was conducted on the clinical and follow-up data of 20 premature infants (gestational age <32 weeks, birth weight <1500 g) who received Ommaya reservoir implantation because of hydrocephalus following IVH. The therapeutic effect of Ommaya reservoir implantation was observed. These patients were divided into cure and treatment failure groups according to their treatment outcomes. The factors influencing therapeutic effects were investigated by univariate analysis.

RESULTSHydrocephalus was relieved significantly at 30 days after Ommaya reservoir implantation. However, some patients showed significantly decreased therapeutic effects since 3 months after operation: during 3-6 months after operation, 7 cases underwent ventriculoperitoneal shunt, 4 cases discontinued treatment because of economic reasons, and 1 case underwent endoscopic third ventriculostomy due to scalp hematoma with skin necrosis. The ventricles of the remaining 8 cases returned to normal size at 12-18 months after operation. As for postoperative complications, secondary IVH was seen in 8 cases, intracranial infection in 2 cases, and scalp hematoma with skin necrosis in 1 case. The univariate analysis revealed significant differences in gestational age, birth weight and duration of hydrocephalus before Ommaya reservoir implantation between the cure and the treatment failure groups (P<0.05).

CONCLUSIONSOmmaya reservoir implantation has a remarkable short-term therapeutic effect on hydrocephalus in premature infants following IVH, but later the effect decreases in some patients. Low gestational age, low birth weight and long duration of hydrocephalus may be the main factors influencing therapeutic effects of Ommaya reservoir implantation.

A case of combined methylmalonic aciduria and homocysteinemia presenting with hydrocephalus as an early manifestation was reported for its rarity to see and to discuss the relationship between metabolic diseases and hydrocephalus by literature review. The case was an infant with seizures and hydrocephalus as an early manifestation of the disease, combined with macrocyticanemia, development retardation and visual hearing function lesions. The EEG showed hypsarrhythmia and the MRI showed hydrocephalus. Plasma homocysteinemia level increased (143.06 umol/L) and urine methylmalonic aciduria was 1483 times beyond normal. Based on gene analysis results and increased methylmalonic aciduria and homocysteinemia levels, combined methylmalonic aciduria and homocysteinemia was confirmed, presenting CblC defect (gene mutations homozygous for c.609G>A). After treatment by venous injection of vitamin B12, oral folic acid and betaine, seizures were controlled and development was progressive with ventricle retraction. It was concluded that hydrocephalus can be the early presentation in children with combined methylmalonic aciduria and homocysteinemia. Doctors should carry out metabolic disease screening for patients with hydrocephalus, especially when the cause of hydrocephalus is uncertain.

The factors related to death and functional recovery after primary pontine hemorrhage (PPH) in Koreans has not been well defined. The authors sought to identify independent predictors of death and functional recovery after PPH using data obtained at a single institute. Data were collected retrospectively on 281 patients with PPH admitted to the Stroke Unit at our hospital between January 1, 2000 and December 31, 2009. Multivariate logistic regression analysis was used to evaluate the associations between selected variables and 30-day mortality and 90-day functional recovery after PPH. One-hundred and ten patients (39.1%) died within 30 days of PPH and 27 patients (9.6%) achieved functional recovery within 90 days. By multivariate analysis, unconsciousness, dilated pupils, abnormal respiration, systolic blood pressure < 100 mmHg, hydrocephalus, and conservative treatment were found to be predictors of 30-day mortality, whereas consciousness, intact motor function, no history of hypertension or diabetes mellitus, intact eye movement, a hematoma volume of < 5 mL, no ventricular hemorrhage, and normally sized ventricle were found to be predictors of 90-day functional recovery. The present findings suggest that systolic hypotension of less than 100 mmHg may predict 30-day mortality and a history of underlying hypertension and diabetes mellitus may predict 90-day functional recovery.

While a delayed intracerebral hemorrhage at the site of a ventricular catheter has occasionally been reported in literature, a delayed hemorrhage caused by venous infarction secondary to ventriculoperitoneal shunting has not been previously reported. In the present case, a 68-year-old woman underwent ventriculoperitoneal shunting through a frontal burr hole, and developed a hemorrhagic transformation of venous infarction on the second postoperative day. This massive venous infarction was caused by bipolar coagulation and occlusion of a large paramedian cortical vein in association with atresia of the rostral superior sagittal sinus. Thus, to eliminate the risk of postoperative venous infarction, technical precautions to avoid damaging surface vessels in a burr hole are required under loupe magnification in ventriculoperitoneal shunting.
