T cell co-inhibitory immune checkpoints, such as PD-1 or BTLA, are bona fide targets in cancer therapy. We used a human T cell reporter line to measure transcriptomic changes mediated by PD-1- and BTLA-induced signaling. T cell receptor (TCR)-complex stimulation resulted in the upregulation of a large number of genes but also in repression of a similar number of genes. PD-1 and BTLA signals attenuated transcriptomic changes mediated by TCR-complex signaling: upregulated genes tended to be suppressed and the expression of a significant number of downregulated genes was higher during PD-1 or BTLA signaling. BTLA was a significantly stronger attenuator of TCR-complex-induced transcriptome changes than PD-1. A strong overlap between genes that were regulated indicated quantitative rather than qualitative differences between these receptors. In line with their function as attenuators of TCR-complex-mediated changes, we found strongly regulated genes to be prime targets of PD-1 and BTLA signaling., Competing Interests: Work on immune checkpoint inhibitors in the W.K. and V.Z. groups is partly supported by a research grant from AstraZeneca., (© 2024 The Authors.)

The successful isolation of DNA (Deoxyribonucleic Acid) is essential for the investigation process of forestry molecular genetics. Samples used are usually retrieved either from soft or juvenile plant organs because of their excellent DNA source. However, in certain cases, aforesaid samples are hard to obtain, as for forensic purposes. Alternatively, woods possess potential as alternative source of DNA whose extraction method has been developed with varying degrees of success. However, to date, effectiveness on tropical wood grown in Indonesia has not been widely reported. Therefore, objective of this study was to compare the results of DNA isolation of various dried and fresh wood samples by using two isolation methods: Cetyl Trimethyl Ammonium Bromide (CTAB) and Qiagen DNeasy Plant Mini Kit (QDPMK). Extraction results were visualized in agarose gels and quantified using Nanophotometer NP80 Implen which were then amplified using two universal primers: ITS and rbcL for detecting DNA signals. Extraction results from dried wood indicated no visualization in the gel, while fresh wood samples showed thick smeared bands on both extraction methods. Quantity test results denoted higher concentration in CTAB-extracted samples compared to samples extracted using QDPMK, in both types of samples, even though both resulted in optical density ratios outside the range of purity (λ260/280: 1,8-2,0 and λ260/230: 2,0, respectively). Success rates of ITS and rbcL primary amplification in dried wood samples were quite low yet outputs from the two methods did not differ significantly. Meanwhile, outcome of ITS and rbcL amplification on fresh wood samples had a fairly high success., (Copyright © 2021 The Chartered Society of Forensic Sciences. Published by Elsevier B.V.

Background: Tetanus is a rare disease caused by Clostridium tetani, which produces tetanolysin and tetanospasmin. In 2018, there were only approximately ten tetanus cases reported in Indonesia. Despite widespread vaccination, especially in low-middle-income countries, tetanus still occurs (mostly in adults) due to the lack of immunization related to religious tenets, cultural belief, or inaccessibility to medical care. In addition, tetanus in the pediatric population shows features which are quite distinct from the adult group., Case Presentation: We report a case of a 7-year-old girl presented to our institution with a history of falling 10 days prior to admission, with only skin laceration on her forehead. For 1 day prior to admission, the patient looked drowsy and difficult to be awakened, accompanied with stiffness of her jaw; we diagnosed her as an unimmunized child with an open depressed skull fracture of her frontal bone and wound infection complicated with "lockjaw." Perioperative management of this rare case is reported and discussed., Conclusion: The pediatric intensive care of such patients requires halting further toxin production, neutralization of circulating toxin, and control of the clinical manifestation induced by the toxin that has already gained access to the central nervous system. The basic tenets of anesthetic care in such case must be well-managed and planned prior to surgery.

Background: Coronavirus disease 2019 (COVID-19) pandemic has affected global health system; in the context of the COVID-19 pandemic, both surgeon and anesthesiologist often dealt with emergency situation, optimal timing of surgery and safety protocol in hospital setting must be implemented with many facets for both patients and health-care providers., Case Description: We reported two cases. Case#1 - A 16-year-old male was referred to our hospital, due to a decreased of consciousness following a motor vehicle accident. Head CT scan revealed an epidural hemorrhage on the left temporoparietal. The patient was suspected for having COVID-19 from the reactivity of his serum against SARS-CoV-2 antigen. Procedures for the confirmation of COVID-19 and surgical preparation caused 12 h delayed from the admission. Nevertheless, the patient was deteriorated clinically before he was transported to the operating room and died after 6 cycles of cardiopulmonary resuscitation. Case#2 - A 25-year-old male was referred to RSHS, due to a decreased of consciousness, diagnosed as bilateral proximal shunt exposed with suspected COVID-19; delay occurred due to unavailability of negative pressure intensive unit for postoperative care. This caused 5760 h (4 days) delayed for bilateral shunt removal and temporary extraventricular drainage., Conclusion: Optimal timing of surgery, a good safety, and health protocol during pandemic in emergency setting are an obligation to protect health providers and patients. A decision-making plan must be organized precisely to maintain alertness, achieve the highest possible standard of care, and outcome in emergency surgical cases. Lack of monitoring must be abated to avoid fatality for patient, especially in emergency surgery setting., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Surgical Neurology International.)

Objective: Diffuse astrocytic tumour (DAT) is a diffuse infiltrative astrocytoma tumour accompanied by molecular parameters such as the presence or absence of isocitrate dehydrogenase (IDH) gene mutations. Ki-67 is a marker for DAT proliferation, while programmed death ligand 1 (PD-L1) indicates an immune evasion mechanism. This study aimed to analyze the correlation among mutant IDH1 R132H, Ki-67, and PD-L1 immunoexpression in the DAT., Methods: A cross-sectional study was carried out on 30 paraffin blocks of DAT cases. Paraffin block samples consist of grade II (n=14), grade III (n=8), and grade IV (n=8). In this study, the immunohistochemistry-staining of mutant IDH1 R132H, Ki-67, and PD-L1 were carried out to determine the frequency of DAT with IDH1 mutations., Results: Our study shown the frequency of IDH1 mutations in grade II 50.0% (7/14), grade III 37.5% (3/8), and grade IV 12.5% (1/8). Our study also showed a difference in Ki-67 and PD-L1 expression between each the degree of DAT histopathology (p=0.0001 and p=0.002, respectively). There was an association between both mutant IDH1 R132H, and Ki-67 with PD-L1 expression in DAT (p=0.0087 and p=0.0049, respectively)., Conclusion: DAT with the mutant IDH1 is frequently observed in grade II and small number of grade III. The expression of wild type IDH1, Ki-67, and PD-L1 were found to be higher in high grade DAT (grade III and grade IV). There is a correlation between each of mutant IDH1 status and Ki-67 with PD-L1 expression in DAT.

Coronavirus Infectious Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; previously known as 2019 novel coronavirus) is an emerging and rapidly evolving health issue that has been widespread globally and become a pandemic. The typical symptoms of COVID-19 are: a cough, shortness of breath and a fever; from the initial estimates, about 15% of COVID-19 patients present with severe respiratory symptoms and requires hospitalization and intensive care. Recent accumulated evidences showed that the neurological insults also occurred in patients with COVID-19, ranging from mild headache to severe neurological symptoms. In this review, we summarize the COVID-19 and neurological significance of COVID-19., (© 2020 The Author(s).)

Background: Bioinformatics analysis integrating microenvironmental factors and single cell analysis segregated the glioblastoma (GBM) subtype into 3 subtypes: proneural, classic, and mesenchymal. Mesenchymal GBM tends to have the worst survival but benefits from aggressive treatment protocols. Therefore, it is clinically meaningful to identify relevant biomarkers to distinguish the mesenchymal subtype. Moreover, in developing nations with limited resources, rigorous examinations are costly and inefficient for patient care., Methods: In this study, we analyzed The Cancer Genome Atlas (TCGA)-Glioblastoma and TCGA-Low-Grade Glioma RNA sequencing (RNAseq) cohorts and confirmed that the mesenchymal subtype was associated with the worst prognosis., Results: We identified periostin (POSTN) as a mesenchymal subtype biomarker with prognostic value across histologic grades and confirmed the reliability of POSTN by gene expression meta-analysis combining TCGA, Chinese Glioma Genome Atlas (CGGA) and REMBRANDT (Repository for Molecular Brain Neoplasia Data) GBM cohorts (hazard ratio, 1.71 [range, 1.47-2.07], n = 693) and LGG cohorts (hazard ratio, 2.55 [range, 1.61-4.05], n = 1226)., Conclusions: By using available online glioma databases, our study provided an insight into the expression of POSTN as an independent predictor for patients with glioma (GBM and LGG) and could be useful for diagnostic simplification to identify high-risk groups., (Copyright © 2019 Elsevier Inc.

Purpose: A head injury (HI) may cause a skull fracture, which may or may not be associated with injury to the brain. In essence, a skull base fracture (SBF) is a linear fracture at the base of the skull. Loss of consciousness and Glasgow coma score (GCS) may vary depending on an associated intracranial pathology. The pathomechanism is believed to be caused by high energy impact directly to the mastoid and supraorbital bone or indirectly from the cranial vault. Aim of this study is to define the correlation between SBF and intracranial hemorrhage (ICH) in patients with HI., Methods: Analysis of data obtained from a retrospective review of medical records and from a systematized database pertaining to diagnostic criteria of SBF patients based only on clinical symptoms associated with ICH caused by HI treated in the Department of Neurosurgery at Dr. Hasan Sadikin Hospital, Bandung, Indonesia from January 1, 2012 to December 31, 2017. The exclusion criteria included age less than 15 years and no head computed tomography (CT) scan examination provided., Results: A total of 9006 patients were included into this study in which they were divided into 3 groups: group 1, HI with no ICH; group 2, HI with single ICH and group 3, HI with multiple ICH. In all the SBF cases, SBF at anterior fossa accounted for 69.40% of them, which were mostly accompanied with mild HI (64.70%). Severity of HI and site of SBF correlated with the existence of traumatic brain lesions on CT scan, thus these factors were able to predict whether there were traumatic brain lesions or not. Most of the patients with epidural hemorrhage (EDH) has single traumatic lesion on CT scan, whereas most of the patients with cerebral contusion (CC) has multiple traumatic lesions on CT scan. On patients with both traumatic brain injury and SBF, most of the patients with anterior fossa SBF has EDH; whereas most of the patients with middle fossa SBF were accompanied with CC. Surgery was not required for most of the patients with SBF., Conclusion: SBFs were strongly correlated with traumatic ICH lesions patients with anterior fossa SBF were more likely to suffer EDH whereas with middle fossa SBF were more likely to suffer CC., (Copyright © 2019 Chinese Medical Association.

Purpose: Mild traumatic brain injury (TBI) is common but accurate diagnosis and its clinical consequences have been a problem. Maxillofacial trauma does have an association with TBI. Neuron-specific enolase (NSE) has been developed to evaluate neuronal damage. The objective of this study was to investigate the accuracy of NSE serum levels to detect mild brain injury of patients with sustained maxillofacial fractures during motor vehicle accidents., Methods: Blood samples were drawn from 40 healthy people (control group) and 48 trauma patients who had sustained isolated maxillofacial fractures and mild brain injury in motor vehicle accidents. Brain injuries were graded by Glasgow Coma Scale. In the trauma group, correlations between the NSE serum value and different facial fracture sites were also assessed., Results: The NSE serum level (mean ± SD, ng/ml) in the 48 patients with maxillofacial fractures and mild TBI was 13.12 ± 9.68, significantly higher than that measured in the healthy control group (7.72 ± 1.82, p < 0.001). The mean NSE serum level (ng/ml) in the lower part of the facial skeleton (15.44 with SD 15.34) was higher than that in the upper facial part (12.42 with SD 7.68); and the mean NSE level (ng/ml) in the middle-and lower part (11.97 with SD 5.63) was higher than in the middle part (7.88 with SD 2.64)., Conclusion: An increase in NSE serum levels can be observed in patients sustained maxillofacial fractures and mild brain injury., (Copyright © 2019 Daping Hospital and the Research Institute of Surgery of the Third Military Medical University.

Background: Dermoid cysts are rare tumors usually seen in the midline structure of the brain but rarely arise in the petrous apex and cavernous sinus. There have been very few reports of dermoid cysts arising in the infratemporal fossa, with scarce anatomic descriptions. Here we report the case of a patient with a dermoid cyst in the left infratemporal fossa., Case Description: The patient was a 43-year-old female with complaints of nonspecific headaches. A computed tomography (CT) scan revealed a cystic lesion measuring 25 × 18 × 15 mm in the left infratemporal fossa that had expanded the foramen ovale. The same lesion was observed as a high-intensity area on T1-weighted magnetic resonance imaging (MRI) with fat saturation. Diffusion-weighted MRI showed no restriction, unlike in cases of epidermoid cysts. A left fronto-temporo-sphenoidal craniotomy with a detachment of the zygoma was performed to approach the lesion. The tumor wall was continuously attached to the dura, although the tumor itself was entirely extradural in location. The V3 branch of the trigeminal nerve was firmly attached around the tumor. The tumor was cystic, and it shrunk after the fatty yellowish contents were suctioned. Complete resection was achieved without complications. A pathological analysis enabled the diagnosis of a dermoid cyst. No tumor recurrences or associated complications were observed at the 1-year follow-up., Conclusions: Dermoid cysts in the infratemporal fossa are extremely rare. However, tumor resections can be performed safely and efficaciously using anatomically detailed preoperative planning., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Traumatic brain injury (TBI) is a major cause of mortality in many countries. According to the World Health Organization, traffic crashes are a leading cause of death, with 1.25 million deaths worldwide in 2013. A 2013 global road safety report listed 68 low-to-middle income countries that had an increased mortality rate owing to traffic accidents. The aim of this study was to analyze feasibility of use of an online prognostic model from the Medical Research Council Corticosteroids Randomization After Significant Head Injury (CRASH) trial collaborators in our center., Methods: This is a cross-sectional retrospective study of 229 patients with TBI who were admitted to the Neurosurgery Unit at Dr. Hasan Sadikin Hospital, Bandung, from July to December 2016., Results: During the study period, 495 patients with TBI were admitted; 229 patients were included in the study. Several variables were analyzed using independent statistical methods before being included in the online CRASH calculator, including Glasgow Coma Scale score (P = 0.000), pupillary reaction to light (P = 0.000), major extracranial injury (P = 0.002), and interval following incidence (P = 0.000). Statistical analysis showed that the online CRASH prognostic model reliably predicted 14-day mortality rate (P = 0.000) with 91.6% sensitivity and 95.1% specificity., Conclusions: The online CRASH model is a good prognostic model that can be used for patients with TBI in many developing countries., (Copyright © 2018 Elsevier Inc.

Background: Tuberculous meningitis (TBM) is an endemic infectious disease in developing countries, and it can become a serious illness in children. Treatment of TBM is more difficult and prone to failure than treatment of pulmonary tuberculosis. TBM causes hydrocephalus, cerebral edema, increased intracranial pressure, global ischemia, and neurologic deficits, which disturb cellular metabolism and increase lactate levels. A reliable, widely available clinical indicator of TBM severity is needed. Successful treatment of TBM is assessed using the Glasgow Outcome Scale (GOS)., Methods: This prospective cohort study included 34 patients with TBM and acute hydrocephalus who had undergone fluid diversions and were admitted to Dr. Hasan Sadikin Hospital in Bandung from 2014 to 2015. A portable machine for blood glucose measurement was used to measure lactate concentrations. Statistical significance was defined as P ≤ 0.05., Results: Average levels of plasma and cerebrospinal fluid (CSF) lactate were 1.99 ± 0.70 mmol/L and 3.04 ± 1.05 mmol/L, respectively. A significantly higher level of lactate was observed in CSF compared with plasma. Preoperative plasma lactate was negatively correlated to GOS (r = -0.539; P = 0.013), and CSF lactate was negatively correlated to GOS (r = -0.412; P = 0.027). Average lactate levels in CSF (central) were higher than plasma (peripheral) levels. GOS scale of patients decreased with increased plasma and CSF lactate levels., Conclusions: Examination of plasma and CSF lactate levels should be included in routine examinations to determine extent of cellular damage and GOS score in patients with TBM and acute hydrocephalus who have undergone fluid diversions., (Copyright © 2017 Elsevier Inc.

Introduction: Little is known about neurosurgery patient outcomes in Indonesia. Our study sought to describe patient characteristics, health care pathways, health-related quality of life, and health/rehabilitation care needs of patients admitted to, and discharged from, a major neurosurgery department., Methods: Eligible patients were aged ≥18 years admitted to the Neurosurgery Department in a regional referral hospital in Bandung, Indonesia. Baseline data was collected on admission. An in-person interview (in the Indonesian language) was held 1 to 2 days pre-discharge. Sociodemographic along with clinical characteristics, Glasgow Coma Scale (GCS), and EQ-5D-5L data were collected., Results: A total of 217 patients were admitted, 37 died before discharge, and a pre-discharge interview was undertaken by 178 (82%). Almost half (48%) were admitted because of injury, 38% brain tumour, 10% acute illness, and 4% other conditions. The mean age was 41 years. On admission, 63% had a mild Glasgow Coma Scale, 31% moderate, and 3% severe. The average hospital stay was 8 days for injury and 24 days for illness patients. Prior to discharge, one-third, or less, of the 178 patients interviewed reported "no problems" in the EQ-5D dimensions of mobility (32%), self-care (27%), usual activities (16%), and pain/discomfort (32%), whereas 70% reported "no problems" with anxiety/depression., Conclusion: A large proportion of patients are being discharged with considerable levels of difficulty in four of the five EQ-5D dimensions. This stresses the importance of providing good follow-up and support of patients and their families., (Copyright © 2017 John Wiley & Sons, Ltd.)

Introduction: Support of neurosurgery patients following discharge from hospital is important. Currently, little is known about patients' in low- and middle-income countries before and after their hospital treatment. This companion paper reports patients' pathways before and after hospital admission and the feasibility of following up this ill-patient population by telephone., Methods: Eligible patients were aged ≥18 years admitted to the Neurosurgery Department in Dr. Hasan Sadikin Hospital-a regional referral hospital in Bandung City, Indonesia. Clinical data were collected on admission by clinicians. In-person interviews were undertaken with a clinical research nurse 1 to 2 days pre-discharge, and telephone follow-up interviews at 1, 2, and 3 months post-discharge. Information was also collected on pathways prior to admission and following discharge. The number of contact attempts for each patient interview was documented, as was the overall acceptability of undertaking a telephone interview., Results: Of 178 patients discharged from hospital, 12 later died. Of the remaining 166 patients, 95% were able to be followed up to 3 months. Two-thirds of patients had been referred from another hospital. Patients came from, and were discharged to, locations throughout the West Java region. At the 1-month interview, 84% participants reported that they had had a follow-up consultation with a health professional-mostly with a neurosurgeon., Conclusion: This study has shown that, with a neurosurgery nurse delegated to the role, it is feasible to conduct follow-up telephone interviews with patients after discharge from a neurosurgery ward and that in fact such follow-up was appreciated by patients., (Copyright © 2017 John Wiley & Sons, Ltd.)

Objective: Surgical management of giant skull osteomas Osteomas are benign, generally slow growing, bone forming tumors limited to the craniofacial and jaw bones., Materials and Methods: A retrospective review of all cases of osteoma diagnosed from 2009 to 2013 treated in our hospital. The data collected included age at diagnosis, gender, lesion location, size, presenting and duration of symptoms, treatment, complication and outcome., Results: During our study period there were 15 cases that were treated surgically. Their mean age was 42 years (range: 15-65 years) and all of our patients were female. The average duration of symptoms was 3 years and size varying from 4 cm to 12 cm. Eight patients complained of headache, whereas 6 patients complained about esthetics, and 1 patient presented with proptosis. The tumor was excised by cutting the base of the tumor and then residual tumor was grinded using a round head cutting bar. Osteoma was removed with esthetically acceptable appearance., Conclusion: There were no major complications during operative and postoperative period. Although osteomas are usually slow growing but surgery is usually performed due to esthetic reasons. It is important to plan an appropriate surgical approach that minimizes any damage to the adjacent structures., Competing Interests: Conflict of Interest: None declared.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare low-grade sarcoma of the fibroblast originating from the dermal layer of the skin, characterized by a locally aggressive growth and high rate of local recurrence., Case Description: Two patients underwent a wide radical excision of recurrent scalp DFSP which was reconstructed with translational skin flap and split-thickness skin graft. We described above cases several years ago with a local excision of the tumor; recently, they developed local recurrence of DFSP with calvarial involvement. We then performed a wide radical excision, with craniectomy of the cranial defect followed by cranioplasty using titanium mesh, continuing with reconstruction., Conclusion: A successful treatment and management depends on achieving local control and preventing cosmetic and functional deficit; all efforts should be made for complete excision. Postoperative follow-up recommended for highly suspicious cases and annual checkups should be performed up to 5 years after definitive therapy., Competing Interests: There are no conflicts of interest.

Background: Traumatic brain injury (TBI) constitutes a critical public health and socioeconomic problem. As one of the leading causes of mortality and disability from road traffic crashes, the incidence of TBIs is increasing with increasing motor vehicle usage. Understanding the prevalence and describing the characteristics of TBI are crucial for successful implementation of prevention and treatment efforts to reduce the mortality and morbidity caused by TBIs., Methods: We studied cases of moderate and severe TBI resulting from motorcycle crashes from January 1, 2013 to June 30, 2014. Variables studied included sex, age, time interval (from crash to arrival at the emergency department), alcohol consumption, helmet use, severity of TBI, choice of treatment, and the outcome., Results: A total of 2108 head injury cases were seen at the emergency department during this period, 1324 (62.8%) of which resulted from motorcycle crashes. Of those cases, 30.7% (407 cases) were categorized as moderate or severe TBI with 29.2% mortality. Most of the patients were male (80.8%), <60 years old (96.1%), and did not wear a helmet (71.2%). More than half of the cases (56.7%) arrived at the emergency department within 6 hours, 14.0% of the cases were under alcohol intoxication, and 37.8% of the cases were operated on., Conclusions: This preliminary analysis highlights the need to address road safety, especially with respect to helmet use and drink driving, to reduce the burden of TBIs in Bandung., (Copyright © 2017 Elsevier Inc.

Background: Medulloblastoma is a highly malignant embryonal tumor which commonly arises in the cerebellum. It is relatively rare and accounts for less than 2% of all primary brain tumors. The tumor primarily occurs in childhood; however, rarely, it may be found in adult population. In addition, medulloblastoma in adult population shows features which are quite distinct from the pediatric group., Case Description: We report the case of a 33-year-old man who presented to our institution with a history of blurred vision of both eyes for 5 months preceded by intermittent headache since the previous year. Preoperative investigation suggested a posterior fossa mass and we suspected an ependymoma. The patient underwent ventriculoperitoneal shunt and craniotomy tumor removal, followed by radiotherapy. Histopathological and immunohistochemical examination were performed, and the results showed a diagnosis of medulloblastoma., Conclusion: This case is exceptional because adult medulloblastoma occurrence in our center is extremely rare, and the diagnosis can only be established through histopathological and immunohistochemical studies.

Multiple histopathology of meningioma is a condition in which the patient has more than one histopathology feature of meningioma in different intracranial locations, with or without sign of neurofibromatosis. Meningiomas are the most common, non-glial, primitive intracranial tumors; their prevalence among operated tumors is around 13-19%. They may occur at any age, but have a peak incidence around 45 years of age. The incidence of multiple intracranial meningiomas varies from 1% to 10% in different series, and the frequency of multiple meningiomas without neurofibromatosis was reported to be <3%.

Pilomyxoid astrocytoma (PMA) is a recently described entity with similar features to pilocytic astrocytoma but with a rare occurrence. As a new diagnosis, no treatment guideline of PMA has been established; but generally, as for any low-grade gliomas, radical resection is performed if the location is favorable. In this report, we wished to share our experience treating the PMA. The authors presented a case of a 7-year-old girl with bitemporal hemianopia. From the history, the patient had a 4-month history of headache, following with nausea and projectile vomiting 1 week before hospital admission. Past history of seizure, weakness of left extremities, and decreased consciousness were reported. Computed tomography (CT) scanning showed acute obstructive hydrocephalus and an isohypodense mass at suprasellar region with the cystic component. We performed ventriculo-peritoneal-shunt to reduce the acute hydrocephalus, followed by craniotomy tumor removal 2 weeks later. The patient underwent radiotherapy and medical rehabilitation. Diagnosis of PMA was made on the basis of pathologic anatomy result, which showed a myxoid background with pseudorosette. Postoperative CT showed a residual tumor at right parasellar area without hydrocephalus. After the surgery, the treatment was followed with radiotherapy for 20 times within 2 months. Postradiation CT performed 1-year later showed a significant reduction of the tumor mass. There were no new postoperative deficits. The patient had improvement of the visual field and motor strength. The authors reported a case of a 7-year-old girl with PMA. Surgical resection combined with radiotherapy was performed to control the growth of PMA. More observation and further studies are required to refine the treatment methods.

Introduction: Spinal trauma is the cause of high mortality and morbidity, the fall from height as mechanism that can cause a wide variety of lesions, associated both with the direct impact on the ground and with the deceleration. In such fall cases greater heights and higher mortality are involved., Presentation of Case: We report the successful management of life-threatening hollow-organ perforation following thoracolumbar spinal injury., Discussion: Perforation of the hollow-organ in the setting of thoracolumbar trauma may delay the diagnosis and can have devastating consequences., Conclusions: This case supports the recommendation for neurosurgeon in the setting of thoracolumbar injury that perforation of the hollow-organ can have devastating consequences. It is vital to achieve an early diagnosis to improve survival rate., (Copyright © 2015. Published by Elsevier Ltd.)

Background: Brain tumor patients have a tendency to suffer from psychiatric disturbances. One of the most frequent disturbance experienced by frontal area tumor patients are personality changes., Case Description: In this paper, the authors report a 28-year-old male patient who presented with headache and personality changes, with no other neurological disturbance. The patient became increasingly pensive and apathetic with frontal and cerebellopontine angle tumor. The diagnosis is based on computed tomography scanning images, and histopathological examination of the excised tumor results in meningioma., Conclusion: Before the operation was performed, the patient suffered from personality changes and suicidal tendencies. After the operation, the patient's suicidal tendency was gone, but the personality changes still persist. For this reason, a comprehensive management of the patient is required, including postoperative pharmacological and psychological treatment.

Microsurgery techniques are useful innovations towards minimizing the insult of canal stenosis. Here, we describe the trumpet laminectomy microdecompression (TLM) technique, advantages and disadvantages. Sixty-two TLM patients with lumbar disc herniation, facet hypertrophy or yellow ligament or intracanal granulation tissue. The symptoms are low back pain, dysesthesia and severe pain on both legs. Spine levels operated Th11-S1; the patients who had trumpet-type fenestration, 62.9% had hypertrophy of the facet joint, 11.3% had intracanal granulation tissue, 79.1% had hypertrophy of the yellow ligament and 64.5% had disc herniation. The average of procedure duration was 68.9 min and intraoperative blood loss was 47.4 mL. Intraoperative complications were found in 3.2% of patients, with dural damage but without cerebrospinal fluid leakage. The TLM can be performed for all ages and all levels of spinal canal stenosis, without the complication of spondilolistesis. The TLM has a shorter duration, with minimal intraoperative blood loss.

Object: Glioblastoma is the most aggressive malignant brain tumor, and overall patient survival has not been prolonged even by conventional therapies. Previously, the authors found that chemically synthesized glycans could be anticancer agents against growth of a series of cancer cells. In this study, the authors examined the effects of glycans on the growth of glioblastoma cells both in vitro and in vivo., Methods: The authors investigated not only the occurrence of changes in the cell signaling molecules and expression levels of various proteins related to cell death, but also a mouse model involving the injection of glioblastoma cells following the administration of synthetic glycans., Results: Synthetic glycans inhibited the growth of glioblastoma cells, induced the apoptosis of the cells with cleaved poly (adenosine diphosphate-ribose) polymerase (PARP) expression and DNA fragmentation, and also caused autophagy, as shown by the detection of autophagosome proteins and monodansylcadaverine staining. Furthermore, tumor growth in the in vivo mouse model was significantly inhibited. A dramatic induction of programmed cell death was found in glioblastoma cells after treatment with synthetic glycans., Conclusions: These results suggest that synthetic glycans could be a promising novel anticancer agent for performing chemotherapy against glioblastoma.

Background: Giant dermatofibrosarcoma protuberans (DFSP) of the scalp is a rare case, which is an intermediate grade soft tissue neoplasm originating from the dermal layer of the skin, which usually occurs in adults., Case Description: We describe such a case in a 26-year-old male. A wide local excision of the tumor with a generous tissue margin was performed; microscopic and immunohistochemical findings established the diagnosis of recurrent DFSP., Conclusion: Our case is unique in that it is presented as a dermatofibrosarcoma protuberans of the scalp, which is an extremely rare clinical entity, and the patient remains well after 14 months with no further treatment, without any tumor recurrence.

Background: The incidence of extraorbital giant cell angiofibroma (GCA) is rare, with only one case located in the scalp reported in the literature. The morphological hallmark is histopathological examination showing richly vascularized pattern-less spindle cell proliferation containing pseudovascular spaces and floret-like multinucleate giant cells., Case Description: We report a case of a 30-year-old female with a primary complaint of a painless solitary nodule arising on the left parietal region of the scalp. Complete tumor removal through surgical intervention was achieved, and the postoperative period was uneventful., Conclusion: Diagnosing a highly vascularized tumor in the head and neck is challenging. Our case is unique in that it is presented as a GCA of the scalp, which is an extremely rare clinical entity, and also demonstrated bone destruction.

Disasters bring consequences of negative impacts on the environment and human life. One of the common cause of critical condition is traumatic brain injury (TBI), namely, epidural (EDH) and subdural hematoma (SDH), due to downfall hard things during earthquake. We proposed and analyzed the user response, namely neurosurgeon, general doctor/surgeon and nurse when they interacted with TBI computer interface. The communication systems was supported by TBI web based applications using emergency broadband access network with tethered balloon and simulated in the field trial to evaluate the coverage area. The interface consisted of demography data and multi tabs for anamnesis, treatment, follow up and teleconference interfaces. The interface allows neurosurgeon, surgeon/general doctors and nurses to entry the EDH and SDH patient's data during referring them on the emergency simulation and evaluated based on time needs and their understanding. The average time needed was obtained after simulated by Lenovo T500 notebook using mouse; 8-10 min for neurosurgeons, 12-15 min for surgeons/general doctors and 15-19 min for nurses. By using Think Pad X201 Tablet, the time needed for entry data was 5-7 min for neurosurgeon, 7-10 min for surgeons/general doctors and 12-16 min for nurses. We observed that the time difference was depending on the computer type and user literacy qualification as well as their understanding on traumatic brain injury, particularly for the nurses. In conclusion, there are five data classification for simply TBI GUI, namely, 1) demography, 2) specific anamnesis for EDH and SDH, 3) treatment action and medicine of TBI, 4) follow up data display and 5) teleneurosurgery for streaming video consultation. The type of computer, particularly tablet PC was more convenient and faster for entry data, compare to that computer mouse touched pad. Emergency broadband access network using tethered balloon is possible to be employed to cover the communications systems in disaster area.

Most penetrating skull injuries are caused by gun shot wounds or missiles. The compound depressed skull fracture represents an acute neurosurgical emergency. Management and diagnosis of such cases have been described, but its occurence following a fall onto a piece of wood is quite unusual. A 75-year-old female fell onto a piece of wood that penetrated her skull on the left frontal region and was treated in our department. The patient had no neurological deficits during presentation. She was managed surgically and removal of the wooden object was performed to prevent early or late infection complications. Wooden foreign bodies often pose a different set of challenges as far as penetrating injuries to the brain are concerned. Radiological difficulties and increased rates of infection due to its porous nature make these types of injuries particularly interesting. Their early diagnosis and appropriate treatment can minimize the risk of complications.

Introduction: Tuberculum Sellae Meningioma is one of the most challenging surgeries among neurosurgeons. Many approaches have been established in the effort of removing the tumor and some of them are supported by an advanced neurosurgical technology. In this study, we aim to compare the efficacy of the two most common approaches, the pterional and the unilateral frontal., Materials and Methods: This was a restrospective study that aimed to observe the efficacy of the two most common approaches used in our center, the pterional and the unilateral frontal, in resecting the tuberculum sellae meningioma, which was held in Dr. Hasan Sadikin General Hospital, Bandung, from July 2007-July 2010. Twenty patients were enrolled with half of them operated by the pterional approach and the rest by unilateral frontal approach. We evaluated six parameters: tumor size, degree of tumor removal, surgery duration, post-operative cerebral edema, patients' outcome, and length of stay, which were evaluated to take measure of the efficacy of each procedure., Results: We found that the pterional approach gave more advantages than the unilateral frontal. Total tumor removal, especially in tumor size ≥ 3 cm was achieved in a greater number of subjects in the pterional (P<0.023). Other advantages of the pterional compared to the unilateral frontal were a shorter surgical duration (P=0.024), shorter length of stay (P=0.009) and less frequency of post-operative cerebral edema incidence (P=0.023)., Conclusion: According to our facilities and conditions, it seems that the pterional approach have more advantages than the unilateral frontal approach in tuberculum sellae meningioma surgery.

Background: Surgical removal of jugular foramen (JF) neurinomas remains controversial because of their radicality in relation to periosteal sheath structures., Objective: To clarify the particular meningeal structures of the JF with the aim of helping to eliminate surgical complications of the lower cranial nerves (LCNs)., Methods: We sectioned 6 JFs and examined histological sections using Masson trichrome stain. A consecutive series of 25 patients with JF neurinomas was also analyzed, and the MIB-1 index of each excised tumor was determined., Results: In the JF, meningeal dura disappeared at the nerve entrance, forming a jugular pocket. JF neurinomas were classified into 4 types: subarachnoid (type A by the Samii classification), foraminal (type B), epidural (type C), and episubdural (type D). After an average follow-up of 9.2 years, tumors recurred in 9 cases (36%). Type A tumors did not show regrowth, unlike type B tumors, in which all recurred. Radical surgery by the modified Fisch approach did not contribute to tumor radicality in type C and D tumors, even in cases in which LCN function was sacrificed. In preserved periosteum, postoperative LCN deterioration was decreased. Bivariate correlation analysis revealed that jugular pocket extension, tumor removal, MIB-1 greater than 3%, and reoperation or gamma knife use were significant recurrence factors., Conclusion: For LCN preservation, the periosteal layer covering the cranial nerves must be left intact except in patients with a subarachnoid tumor. To prevent tumor regrowth, postoperative gamma knife treatment is recommended in tumors with an MIB-1 greater than 3%.

BACKGROUND.: Traumatic brain injury (TBI) remains a major cause of death and disability. Oxidative stress is an important element of the injury cascade following TBI. Progressive compromise of antioxidant defenses and free radical-mediated lipid peroxidation are one of the major mechanisms of secondary TBI. NR2B is a glutamate receptor and its activation is caused by TBI increasing a brain cell death, along with caspase-3 as a hall mark of apoptosis. Glutathione is a potent free radical scavenger that might prevent secondary TBI damage and inhibited apoptosis. MATERIALS AND METHODS.: In the present study, it aims to demonstrate the effect of glutathione on inhibition of brain oxidative damage in a TBI rat model. RESULTS.: In this study, the expressions of mRNA NR2B in placebo group and groups with glutathione administration at 0, 3, and 6 hours after TBI were 328.14, 229.90, 178.50, and 136.14, respectively (P<0.001). The highest caspase-3 expression was shown in placebo group with 66.7% showing strong positive results (>80%); as expected, glutathione administered in 0, 3, and 6 hours groups had lower strong positive results of 50%, 16.7%, and 16.7%, respectively, (P=0.025). CONCLUSION.: In conclusion, this study showed that glutathione administration in a TBI rat model decreased NR2B gene- and caspase-3 protein-expression that lead to the inhibition of brain cell death. Our results suggest that glutathione, as a potent free radical scavenger, has a brain cell protective effect against oxidative damage and cell death induced by TBI in rat model.

Objectives: The study aimed to assess outcome, including level of disability, following Japanese encephalitis (JE) in children in Indonesia., Methods: A cohort of children diagnosed with laboratory-confirmed JE from January 2005 to August 2006 was followed-up, with disability measured at least 4 months after discharge from hospital. An assessment tool that can be used to rapidly determine practical level of disability and the likelihood that a child will be able to live independently after illness, the Liverpool Outcome Score, was used., Results: Of 72 children with JE, determination of outcome was possible for 65 (90%). Sixteen died in hospital or before follow-up assessment (25%). Sixteen children (25%) had severe sequelae, indicating their function was impaired enough to likely make them dependent. Five (7%) had moderate sequelae and 12 (18%) had minor sequelae. The remaining 16 children (25%) were considered to have recovered fully., Conclusions: Half of the children with JE either died or were left with serious disabilities likely to impair their ability to lead independent lives, demonstrating the severe impact of JE. Immunization can effectively prevent JE, and an immunization program could avert some of the economic and social burden of JE disease in Indonesia.

A comparative study of the diagnostic value of the ICT-TB test and the TB-Dot test, based on laboratory examination, was carried out in 39 patients suffering from sputum positive pulmonary tuberculosis (25 males and 14 females, aged 16-50 years) and in 48 patients (27 males and 21 females, aged 17-55 years) suffering from non-tuberculosis pulmonary diseases, that had attended the Tembagapura Hospital and the TB Control Health Center Timika-Mimika, Papua. The diagnostic sensitivity of the ICT-TB test was 87.18%, the diagnostic specificity was 81.25%, the diagnostic positive predictive value was 79.07%, the negative predictive value was 88.64%, and the diagnostic efficiency was 83.91%. The diagnostic sensitivity of the TB-Dot test was 93.31%, the diagnostic specificity was 95.83%, the diagnostic positive predictive value was 94.74%, the negative predictive value was 93.85%, and the diagnostic efficiency was 94.25%. The results of the statistical analysis of the data obtained in this study revealed that the diagnostic specificity, the diagnostic positive predictive value and the diagnostic efficiency of the TB-Dot test were significantly higher (p < 0.05) than those of the ICT-TB test. However, the diagnostic sensitivity and the negative predictive value of both tests did not differ significantly (p > 0.05). Viewed from the point of their practicability, it can be justified that the ICT-TB test is a very practicable test, which needs only 15 minutes and does not require special instruments to perform the test, but is more expensive than the TB-Dot test. On the other hand, though the TB-Dot test is not very practicable and relatively time consuming, it has a significantly higher degree of diagnostic value and is much cheaper when compared to the ICT-TB test.
