Résumé
Objective@#: Rathke’s cleft cysts (RCCs) are nonneoplastic cysts. Most of them are asymptomatic and stable; when symptomatic, RCCs are surgically fenestrated and drained. However, the outcomes remain unclear. The authors evaluated the outcomes of RCC decompression. @*Methods@#: Between 2004 and 2019, 32 RCCs were decompressed in a single tertiary institution. The clinical characteristics, intraoperative findings, postoperative complications, and endocrinological and surgical outcomes were retrospectively reviewed. Patients who underwent sequential imaging at least twice and at least 12 months after surgery were included in the analysis. @*Results@#: Patients’ mean age was 40.8±14.9 years, and 62.5% were women. The mean follow-up duration was 62.3±48.6 months. In 21 patients (65.6%), no residual cysts were identified on postoperative magnetic resonance imaging. Of the 18 patients with preoperative visual field defects, 17 (94.4%) experienced postoperative visual improvement. Postoperative complications included endocrinological deterioration in 11 patients (34.4%), permanent diabetes insipidus in 11 (34.4%), infection in four (12.5%), intrasellar hemorrhage in three (9.4%), and cerebrospinal fluid leak in two (6.3%). Follow-up images revealed cyst recurrence in nine patients (28.1%), an average of 20.4 months after surgery; in three patients, the cysts were symptomatic, and resection was repeated. Multivariable analysis revealed that postoperative endocrinological deterioration was the only independent factor associated with cyst recurrence (p=0.028; hazard ratio, 6.800). @*Conclusion@#: Our findings showed that although only cyst fenestration for decompression was performed to preserve pituitary function, more pituitary dysfunction occurred than expected. Besides, the postoperative hormonal deterioration itself acted as a risk factor for cyst recurrence. In conclusion, surgery for RCC should be more careful.

Purpose@#The aims of the study were to develop and evaluate a machine learning model with which to predict postnatal growth failure (PGF) among very low birth weight (VLBW) infants. @*Materials and Methods@#Of 10425 VLBW infants registered in the Korean Neonatal Network between 2013 and 2017, 7954 infants were included. PGF was defined as a decrease in Z score >1.28 at discharge, compared to that at birth. Six metrics [area under the receiver operating characteristic curve (AUROC), accuracy, precision, sensitivity, specificity, and F1 score] were obtained at five time points (at birth, 7 days, 14 days, 28 days after birth, and at discharge). Machine learning models were built using four different techniques [extreme gradient boosting (XGB), random forest, support vector machine, and convolutional neural network] to compare against the conventional multiple logistic regression (MLR) model. @*Results@#The XGB algorithm showed the best performance with all six metrics across the board. When compared with MLR, XGB showed a significantly higher AUROC (p=0.03) for Day 7, which was the primary performance metric. Using optimal cut-off points, for Day 7, XGB still showed better performances in terms of AUROC (0.74), accuracy (0.68), and F1 score (0.67). AUROC values seemed to increase slightly from birth to 7 days after birth with significance, almost reaching a plateau after 7 days after birth. @*Conclusion@#We have shown the possibility of predicting PGF through machine learning algorithms, especially XGB. Such models may help neonatologists in the early diagnosis of high-risk infants for PGF for early intervention.
Résumé
Background@#Long-term growth data of very low birth weight (VLBW) infants are currently collected in the Korean Neonatal Network (KNN) and National Health Insurance Service (NHIS) database. However, variance in the number of infants, check-up time, and check-up parameters led to decreased credibility of cumulated data. We aimed to compare the data on serial growth outcomes by major morbidities from birth to 5 years in VLBW infants between the KNN and NHIS databases. @*Methods@#We combined the NHIS and KNN data of VLBW infants born between 2013 and 2015. The check-up times in the NHIS database were at 4–6, 9–12, 18–24, 30–36, 42–48, and 54–60 months of age, whereas in the KNN were at 18–24 months of corrected age and at 36 months of age.Result: Among 8,864 VLBW infants enrolled based on the birth certificates from the Statistics Korea, 6,086 infants (69%) were enrolled in the KNN, and 5,086 infants (57%) participated in the NHIS health check-up. Among 6,068 infants, 3,428 infants (56%) were enrolled at a corrected age of 18–24 months and 2,572 infants (42%) were enrolled at a chronological age of 33–36 months according to the KNN follow-up registry. However, based on the national birth statistics data, the overall follow-up rate of the KNN at 36 months of age was as low as 29%. The NHIS screening rate was lower at first (23%); however, it increased over time to exceed the KNN follow-up rate. Growth failure (weight under 10th percentile) at corrected ages of 18–24 months and 36 months were more common in the NHIS than KNN (42% vs. 20%, 37% vs. 34.5%). Infants with bronchopulmonary dysplasia and periventricular leukomalacia showed similar rates of growth failure at 2 years but varying rates at 3 years between the KNN and NHIS. @*Conclusion@#By integrating the KNN and NHIS data indirectly at continuous time points according to morbidities, we found that there are discontinuities and discrepancies between the two databases among VLBW infants. Establishing an integrated system by patient level linking the KNN and NHIS databases can lead to better understanding and improved neonatal outcomes in VLBW infants in Korea.
Résumé
Background@#High-grade glioma (HGG) with primary leptomeningeal seeding (PLS) at initial diagnosis is rare. The purpose of this study was to identify its clinical features and to describe the clinical treatment outcomes. @*Methods@#We retrospectively reviewed the medical records of patients with HGG (World Health Organization grade III or IV) at our institution between 2004 and 2019, and patients with PLS at the initial diagnosis were enrolled in the study. Clinical features, such as the location of leptomeningeal seeding, surgical methods, and degree of resection, were sorted based on electronic medical records also containing performance scale, and hematological and serological evaluations. Radiological findings and immunohistochemical categories were confirmed. Furthermore, we sought to determine whether controlling intracranial pressure (ICP) via early cerebrospinal fluid (CSF) diversion increases overall survival (OS) after the initial diagnosis. @*Results@#Of the 469 patients with HGG in our institution, less than 2% had PLS at the initial diagnosis. Most patients suffered from headache, diplopia, and dizziness. Pathological findings included 7 glioblastomas and 2 anaplastic astrocytomas. Seven of the 9 patients underwent CSF diversion. All patients were administered concurrent chemoradiotherapy (CCRT) with temozolomide, 89% of which started adjuvant temozolomide and 33% of which completed the six cycles of adjuvant temozolomide.The OS of patients with HGG and PLS was 8.7 months (range, 4-37), an extremely poor result compared to that of other studies. Also, the 1-year and 2-year OS rates were 44.4% and 16.7%, respectively. @*Conclusion@#Diagnosis and treatment of HGG with PLS are challenging. Aggressive control of ICP followed by early initiation of standard CCRT seems to be helpful in improving symptoms. However, despite aggressive treatment, the prognosis is poor. A multicenter trial and research may be necessary to create a standardized protocol for this disease.

Purpose@#The aim of the study was to investigate risk factors of hearing impairments in preterm infants and analyze factors associated with discrepancies between neonatal hearing screening (NHS) and confirmatory test results. @*Methods@#We analyzed the medical records of 352 preterm infants born at 23 to 32 weeks’ gestational age (GA) who underwent both automated auditory brainstem response (aABR) and confirmatory ABR (cABR). @*Results@#Mean GA, mean birth weight, the incidence of small for GA and cesarean section birth were significantly different between the pass and refer groups on aABR and the normal and abnormal groups of cABR. On univariate analysis, bronchopul monary dysplasia (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.00 to 7.48), intraventricular hemorrhage (OR, 7.02; 95% CI, 1.59 to 31.05), and use of furosemide (OR, 3.84; 95% CI, 1.38 to 10.73) were the factors related to refer results on aABR. Peri ventricular leukomalacia (PVL; OR, 4.00; 95% CI, 1.39 to 11.52) and use of vancomycin (OR, 2.86; 95% CI, 1.22 to 6.73) were associated with abnormal cABR. Twenty-five (7.9%) infants had discrepant aABR and cABR results, particularly males and those in whom vancomycin was used. @*Conclusion@#PVL and use of vancomycin were confirmed as independent risk factors for hearing loss in infants born at less than 32 weeks’ GA. Also, discrepancies between the screening and confirmatory test may occur, especially among male infants and those in whom vancomycin was used. The hearing of infants must be assessed more carefully in such groups regardless of NHS results.
Résumé
OBJECTIVE: Pituitary adenomas (PAs) are often detected as incidental findings. However, the natural history remains unclear. The objective of this study was to evaluate the natural history and growth pattern of untreated PAs.METHODS: Between 2003 and 2014, 59 PAs were managed with clinico-radiological follow up for longer than 12 months without any kind of therapeutic intervention. Tumor volumes were calculated at initial and last follow-up visit, and tumor growth during the observation period was determined. Data were analyzed according to clinical and imaging characteristics.RESULTS: The mean initial and last tumor volume and diameter were 1.83±2.97 mL and 13.77±6.45 mm, 2.85±4.47 mL and 15.75±8.08 mm, respectively. The mean annual tumor growth rate was 0.33±0.68 mL/year during a mean observation period of 46.8±32.1 months. Sixteen (27%) PAs showed tumor growth. The initial tumor size (HR, 1.140; 95% confidence interval, 1.003–1.295; p=0.045) was the independent predictive factor that determined the tumor growth. Six patients (11%) of 56 conservatively managed non-symptomatic PAs underwent resection for aggravating visual symptoms with mean interval of 34.5 months from diagnosis. By Cox regression analysis, PAs of last longest diameter over 21.75 mm were a significant prognostic factor for eventual treatment.CONCLUSION: The initial tumor size of PAs was independently associated with the tumor growth. Six patients (11%) of conservatively managed PAs were likely to be treated eventually. PAs of last follow-up longest diameter over 21.75 mm were a significant prognostic factor for treatment. Further studies with a large series are required to determine treatment strategy.

Liquid biopsy for detection of mutation from circulating tumor DNA is a new technology which is attractive in that it is non-invasive. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) is an effective first line drug for advanced non-small cell lung cancer patients who harbor activating EGFR mutation. During the course of treatment, resistance against TKI arises which can be contributed to EGFR T790M mutation in about 50–60% of patients. Third generation TKI may overcome the resistance. In patients who cannot undergo tissue biopsy due to variable reasons, liquid biopsy is an excellent alternative for the detection of EGFR T790M mutation. However, this relatively novel method requires standardization and vigorous quality insurance. Thus, a standard set of guideline recommendations for liquid biopsy for EGFR mutation testing suitable for the Korean medical community is necessary. In this article, we propose a set of provisional guideline recommendations that was discussed and approved by the Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists.

PURPOSE: Congenital pulmonary airway malformation (CPAM)—a rare developmental anomaly—affects the lower respiratory tract in newborns. By comparing the reliability of diagnostic tools and identifying predictive factors for symptoms, we provide comprehensive clinical data for the proper management of CPAM. METHODS: We reviewed the medical records of 66 patients with prenatally diagnosed CPAM delivered at Severance Children's Hospital between January 2005 and July 2017. RESULTS: We enrolled 33 boys and 33 girls. Their mean gestational age and birth weight were 38.8 weeks and 3,050 g, respectively. Prenatal ultrasonography and postnatal radiography, lung ultrasonography, and chest computed tomography (CT) showed inconsistent findings. Chest CT showed superior sensitivity (100%) and positive predictive value (90%). Among the 66 patients, 59 had postnatally confirmed CPAM, three had pulmonary sequestration, one had cystic teratoma, and one had a normal lung. Of the 59 patients with CPAM, 21 (35%; mean age, 23.4 months) underwent surgery, including 15 who underwent video-assisted thoracoscopy. Twenty-five and 12 patients exhibited respiratory symptoms at birth and during infancy, respectively. Apgar scores and mediastinal shift on radiography were significantly associated with respiratory symptoms at birth. However, none of the factors could predict respiratory symptoms during infancy. CONCLUSION: Radiography or ultrasonography combined with chest CT can confirm an unclear or inconsistent lesion. Apgar scores and mediastinal shift on radiography can predict respiratory symptoms at birth. However, symptoms during infancy are not associated with prenatal and postnatal factors. Chest CT combined with periodic symptom monitoring is important for diagnosing and managing patients with prenatally diagnosed CPAM and to guide appropriate timing of surgery.

Pylorospasm is a cause of delayed gastric emptying in young infants. As in patients with hypertrophic pyloric stenosis, most pylorospasm patients present with projectile vomiting. However, unlike that in case of hypertrophic pyloric stenosis, no persistent pyloric stenotic lesions are present. As such, follow-up using serial gastrointestinal fluoroscopy or ultrasonography can be helpful in diagnosing patients with clinical signs of gastroparesis. Most cases can be treated conservatively, but some patients require pharmacologic treatment. Antispasmodics have been proposed as a treatment for pylorospasm, but their use in neonates and infants has rarely been reported. Herein, we present a case of pylorospasm diagnosed in the neonatal period and successfully treated with intravenous atropine.

BACKGROUND: The purpose of this study was to evaluate the treatment outcome of our optic nerve sheath meningioma (ONSM) case series in terms of preventing tumor growth and preserving vision in ONSM patients. METHODS: Between July 2003 and March 2015, 1,398 patients with intracranial meningioma were diagnosed at Seoul National University Bundang Hospital. Among them, only 13 patients (0.93%) were diagnosed with ONSM and enrolled in the present study. Tumor volume changes of ONSM patients and their visual acuity were evaluated before and after treatments. RESULTS: The median follow-up time was 50 months (range, 12–133 months). Visual acuity was evaluated in 12 of 13 patients, and visual acuity was found to be preserved in 9 of 12 patients (75%). Tumor volume was reduced in all patients. The tumor control rate was 100% in the present study. The difference in tumor volume between pretreatment and last follow-up was statistically significant (p=0.015). CONCLUSION: Intensity-modulated radiotherapy (IMRT) and gamma knife radiosurgery (GKS) could maintain visual acuity and stabilize tumor volume in ONSM patients, suggesting that IMRT and GKS may be effective therapies for ONSM. However, which treatment is the more effective modality must be confirmed by prospective studies and longer-term follow-up.

BACKGROUND: The incidence of brain metastasis (BM) in gynecologic cancers has risen recently, due to prolonged survival times and an early diagnosis. We analyzed treatment outcomes of patients with BM from gynecologic cancers. METHODS: Among 951 patients with BM who were treated in neurosurgical department from July 2003 to February 2016, a total of 20 (2%) patients were from gynecologic cancers. The patients' clinical characteristics were collected by using medical records. There were 14 (66.7%) ovarian cancers, 4 (19.0%) uterine cancers, and 2 (9.5%) cervical cancers. As a primary treatment modality, 11 patients were treated with Gamma Knife surgery (GKS), 6 with surgical resection followed by whole brain radiation therapy (WBRT), and 3 with WBRT only. Overall and progression-free survival according to the primary origin and the primary treatment were analyzed. RESULTS: Median overall survival time was 28 months, and progression-free survival was 15 months. In patients with ovarian cancer, median overall survival did not reach during the follow-up periods and progression-free survival time was 15 months. Median overall survival time in patients who received GKS as the primary treatment was 17 months and that in patients who underwent surgical resection followed by WBRT was 37.3 months (p=0.16). The median value of progression-free survival time in patients who received GKS as the primary treatment was 12 months and that in patients who underwent surgical resection with WBRT was 42 months (p=0.042). Median follow up period of over all patients was 13 months. CONCLUSION: BM from gynecologic cancer is rare (2%), but our findings suggest that the prognosis might not always be poor. In our small series, surgical resection with WBRT was a treatment modality significantly associated with a longer progression-free survival. Additional studies with more cases and multi-institutional cooperation are needed to determine which treatment modality leads to better outcomes.

PURPOSE: With increasing use of extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS) in children, development of standardized strategies for survival prediction has become crucial; however, this has not been accomplished yet. We evaluated the adult scoring systems for survival prediction used for their applicability in pediatric ARDS and validated them. METHODS: A total of 11 children with ARDS receiving ECMO from 2013 to 2014 were evaluated with adult scoring systems, including the Respiratory Extracorporeal-membrane-oxygenation Survival Prediction (RESP), the PRedicting dEath for SEvere ARDS on VV-ECMO (PRESERVE), and the ECMOnet scores. We compared the scores on these scales and the clinical characteristics between survivors and nonsurvivors. RESULTS: Eight of the 11 children died (72.7%). The PRESERVE score (survivors vs. nonsurvivors: 2 vs. 5.25, P=0.048), and the ECMOnet score (4.1 vs. 5.63, P=0.048) were lower in survivors than in nonsurvivors. They correctly predicted mortality prediction. There was no significant difference in the RESP score between survivors and non-survivors (−4.33 vs. −2.62, P=0.63). The parameters that showed significant differences in this study were peak inspiratory pressure, platelet, and delta neutrophil index. All children who were under immunocompromised conditions, such as those with tumors, or underwent hematopoietic stem cell transplantation died. The immunocompromised status should be considered an important factor for survival prediction in children with ARDS. CONCLUSION: This is the first pilot study to apply the survival prediction scoring system to pediatric ARDS with ECMO. It is necessary to establish and modify the survival prediction score system for pediatric ARDS with ECMO.

OBJECTIVE: To investigate the efficacy of adjuvant treatment in patients with high-grade meningioma. METHODS: A retrospective analysis was performed for patients with high-grade meningioma, World Health Organization grade 2 or 3, in a single center between 2003 and 2014. The patients were reviewed according to age at diagnosis, sex, the location of meningioma, degree of tumor resection, histological features, and type of adjuvant treatment. These factors were analyzed by Firth logistic regression analyses. RESULTS: Fifty-three patients with high-grade meningioma were enrolled. Thirty-four patients received adjuvant treatment; conventional radiotherapy or radiosurgery. Clinical follow-up ranged from 13–113 months with a median follow-up of 35.5 months. Gross total removal (GTR), Simpson grade 1 or 2, was achieved in 29 patients and, among them, 13 patients received adjuvant treatment. In the other 24 patients with non-GTR, conventional adjuvant radiotherapy and radiosurgery were performed in 11 and 10 patients, respectively. The other 3 patients did not receive any adjuvant treatment. Radiation-related complications did not occur. Of the 53 patients, 19 patients had suffered from recurrence. The recurrence rate in the adjuvant treatment group was 23.5% (8 out of 34). On the other hand, the rate for the non-adjuvant treatment group was 57.9% (11 out of 19) (odds ratio [OR]=0.208, p=0.017). In the GTR group, the recurrence rate was 7.5% (1 out of 13) for patients with adjuvant treatment and 50% (8 out of 16) for patients without adjuvant treatment (OR=0.121, p=0.04). CONCLUSION: Adjuvant treatment appears to be safe and effective, and could lead to a lower recurrence rate in high-grade meningioma, regardless of the extent of removal. Our results might be used as a reference for making decisions when planning adjuvant treatments for patients with high-grade meningioma after surgery.

BACKGROUND AND PURPOSE: Tumors involving the cerebellopontine angle (CPA) pose a diagnostic challenge due to their diverse manifestations. Head impulse tests (HITs) have been used to evaluate vestibular function, but few studies have explored the head impulse gain of the vestibulo-ocular reflex (VOR) in patients with a vestibular schwannoma. This study tested whether the head impulse gain of the VOR is an indicator of the size of a unilateral CPA tumor. METHODS: Twenty-eight patients (21 women; age=64+/-12 years, mean+/-SD) with a unilateral CPA tumor underwent a recording of the HITs using a magnetic search coil technique. Patients were classified into non-compressing (T1-T3) and compressing (T4) groups according to the Hannover classification. RESULTS: Most (23/28, 82%) of the patients showed abnormal HITs for the semicircular canals on the lesion side. The bilateral abnormality in HITs was more common in the compressing group than the non-compressing group (80% vs. 8%, Pearson's chi-square test: p<0.001). The tumor size was inversely correlated with the head impulse gain of the VOR in either direction. CONCLUSIONS: Bilaterally abnormal HITs indicate that a patient has a large unilateral CPA tumor. The abnormal HITs in the contralesional direction may be explained either by adaptation or by compression and resultant dysfunction of the cerebellar and brainstem structures. The serial evaluation of HITs may provide information on tumor growth, and thereby reduce the number of costly brain scans required when following up patients with CPA tumors.

BACKGROUND: Alongside the extent of removal and patients’ survival in the management of brain tumors, health-related quality of life (HRQOL) has become an important consideration. The purpose of this study is to evaluate the change of HRQOL in brain tumor patients before and after surgery and to assess the associated factors that contribute to the change of HRQOL. METHODS: A total of 258 patients who underwent surgical treatment were enrolled in this study. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire 30 (EORTC QLQ-C30) and the 20-item EORTC QLQ-Brain Neoplasm (QLQ-BN20) were used to assess HRQOL. Patients were asked to fill out the questionnaires before and 3-6 months after surgery. RESULTS: Global QOL (p<0.001) and emotional function (p<0.018) were significantly improved after surgery. Physical function (p=0.015) was significantly aggravated. Among the symptoms, headache, pain and nausea and vomiting were significantly decreased (p<0.01, p=0.041, p<0.001, respectively), while dyspnea, communication deficit and weakness of the legs were increased (p=0.005, p=0.040, and p=0.014, respectively). Preoperative neurologic deficit (p=0.019) and tumor diameter (p=0.016) were significantly related to the patients who showed aggravation of global QOL after brain tumor surgery. In the aggravated global QOL group, common complaints and concerns included role function, appetite loss, financial difficulty and future uncertainty. CONCLUSION: In brain tumor patients, HRQOL has improved after surgery. Role function, appetite loss, financial difficulty and future uncertainty were important factors for HRQOL in brain tumor patients treated with surgery. Although there is National Health Insurance and Medical Aid program in Korea, financial difficulty and future uncertainty are much more important in influencing QOL than previously thought. The results of this short-term follow up preliminary study suggest that several factors were related to HRQOL, Further research is needed to evaluate the long term change of HRQOL and enhance the global QOL by analyze related factors.

BACKGROUND: There have been various reports in the literature regarding the conservative management of pituitary apoplexy, pituitary incidentalomas and Rathke cleft cysts (RCCs). However, to the best of our knowledge, spontaneous involution of cystic sellar mass has rarely been reported. We report 14 cases of cystic sellar masses with spontaneous involution. METHODS: A total of 14 patients with spontaneous regression of cystic sellar masses in our hospital were included. The median age was 35 years (range, 5–67), and 8 patients were male. Clinical symptoms, hormone study and MRI were evaluated for all patients. The initial MRI showed all 14 patients with RCCs. Eight patients were presented with sudden onset of headache, and 1 patient with dizziness. Another patient, a 5-year-old child, was presented with delayed growth. Three patients had no symptoms via regular medical work up. All 14 patients had no visual symptoms. The follow-up period ranged from 5.7 to 42.8 months, with the mean of 17.3 months. RESULTS: The mean initial tumor size was 1.29 cm³ (range, 0.05 to 3.23). After involution, the tumor size decreased to 0.23 cm³ (range, 0 to 0.68) without any treatments. Repeated MRI showed a spontaneous decrease in tumor volume by 78% (range, 34 to 99). The initial MRI showed that the tumor was in contact with the optic chiasm in 7 patients, while compressing on the optic chiasm in 3 patients. Five patients were initially treated with hormone replacement therapy due to hormone abnormality. After the follow-up period, only 2 patients needed a long-term hormone replacement therapy. CONCLUSION: The spontaneous involution of RCCs is not well quantified before. Their incidence has not been well demonstrated, but this phenomenon might be underreported. Conservative management can be a treatment option in some RCCs without visual symptoms, even in those that are large in size and in contact with the optic nerve via imaging study.

This study was performed to validate the effectiveness and safety of concurrent chemoradiotherapy and adjuvant therapy with temozolomide for newly diagnosed glioblastoma multiforme as a standard treatment protocol. Between 2004 and 2011, patients newly diagnosed with glioblastoma who were treated with temozolomide during concurrent chemoradiotherapy and adjuvant chemotherapy were included from a single institution and analyzed retrospectively. The primary endpoint was overall survival, and the secondary endpoints were progression-free survival, response, and safety. A total of 71 patients were enrolled in this study. The response rate was 41% (29/71), and the tumor control rate was 80% (57/71). In the 67 patients who completed the concurrent chemoradiotherapy with temozolomide, the median overall survival was 19 months and the 1- and 2-yr overall survival rates were 78.3% and 41.7%, respectively. The median progression free survival was 9 months, and the 1- and 2-yr progression free survival rates were 33.8% and 14.3%, respectively. The mean duration of survival after progression of disease in salvage treatment group was 11.9 (1.3-53.2) months. Concurrent chemoradiotherapy with temozolomide resulted in grade 3 or 4 hematologic toxic effects in 2.8% of the patients. The current protocol of temozolomide during and after radiation therapy is both effective and safe and is still appropriate as the standard protocol for treatment of glioblastoma. An active salvage treatment might be required for a better prognosis.

We report here the case of a suprasellar cystic germ cell tumor (GCT) initially diagnosed as an arachnoid cyst. A 10-year-old boy experienced headache, dizziness, and diplopia, and was shown to have an approximately 2 cm suprasellar cyst. Two months after endoscopic third ventriculostomy was performed, a 5-6 cm cystic mass with an internal enhancing component was observed in the suprasellar cistern. Serum human chorionic gonadotropin levels were slightly increased in the serum and cerebrospinal fluid (55 and 162 IU/L, respectively) but were strikingly elevated in the cystic fluid (14,040 IU/L). The patient showed complete remission, with only a very small cystic lesion remaining after surgery, chemotherapy, and radiation treatment for a suprasellar mixed GCT. However, follow-up after treatment was complicated by moyamoya syndrome and cerebral infarction. GCT can be considered as a rare differential diagnosis in the case of a suprasellar cystic mass. Evaluation of tumor markers and close follow-up will be necessary.

OBJECTIVE: We performed this study to investigate whether the use of closed-suction drainage following microvascular decompression (MVD) causes cerebrospinal fluid (CSF) leakage. METHODS: Between 2004 and 2011, a total of 157 patients with neurovascular compression were treated with MVD. MVD was performed for hemifacial spasm in 150 (95.5%) cases and for trigeminal neuralgia in 7 (4.5%) cases. The mean age of the patients was 49.8+/-9.6 years (range, 20-69). Dural substitutes were used in 44 (28.0%) patients. Ninety-two patients (58.6%) were underwent a 4-5 cm craniotomy using drainage (drainage group), and 65 (41.4%) did a small 2-2.5 cm retromastoid craniectomy without closed-suction drainage (no-drainage group). RESULTS: Eleven (7.0%) patients experienced CSF leakage following MVD based on the criteria of this study; all of these patients were in the drainage group. In the unadjusted analyses, the incidence of CSF leakage was significantly related with the use of closed-suction drainage following MVD (12.0% in the drainage group vs. 0% in the no-drainage group, respectively; p=0.003; Fisher's exact test). Those who received dural substitutes and the elderly (cut-off value=60 years) exhibited a tendency to develop CSF leakage (p=0.075 and p=0.090, respectively; Fisher's exact test). In the multivariate analysis, only the use of closed-suction drainage was significantly and independently associated with the development of CSF leakage following MVD (odds ratio=9.900; 95% confidence interval, 1.418 to infinity; p=0.017). CONCLUSION: The use of closed-suction drainage following MVD appears to be related to the development of CSF leakage.
