RESUMEN

Pituitary apoplexy (PA) is a clinical syndrome resulting from sudden hemorrhage and/or infarction of the pituitary gland. Recent reports documented the development of PA secondary to treatment with gonadotropin-releasing hormone (GnRH) agonists for prostate cancer. A 52-year-old woman visited our emergency room with a severe headache, occurred 1 day prior. She underwent breast-conserving surgery for breast cancer 1 month prior. She was currently undergoing radiation and hormone therapy, consisting of leuprorelin. Brain contrast-enhanced MRI revealed a pituitary adenoma with internal hemorrhage in the sellar and suprasellar areas. Pachymeningeal enhancement was observed along the retroclival and bilateral frontal areas. The patient was diagnosed with PA and aseptic meningitis. The patient underwent total excision via transsphenoidal surgery 8 days after admission. The patient was pathologically diagnosed with a pituitary adenoma with necrosis. On immunochemical staining, the tumor was positive for follicle-stimulating hormone. The follow-up MRI revealed no evidence of residual tumor or an improved pachymeningeal enhancement. She is currently undergoing follow-up at the neurosurgery and endocrinology outpatient departments with no noted complications. In breast cancer patients receiving GnRH agonist therapy, PA may be rare complication.

RESUMEN

Objective@#: Spinal cord stimulation (SCS) is an effective treatment for chronic neuropathic pain. However, its clinical efficacy in regard to specific types of pain has not been well studied. The primary objective of this study was to retrospectively analyze the clinical outcomes of paddle-type SCS according to the type of neuropathic pain. @*Methods@#: Seventeen patients who underwent paddle-lead SCS at our hospital were examined. Clinical outcomes were evaluated pre- and postoperatively (3 months, 1 year, and last follow-up) using the Neuropathic Pain Symptom Inventory (NPSI). The NPSI categorizes pain as superficial, deep, paroxysmal, evoked, or dysesthesia and assess the duration of the pain (pain time score). Changes in NPSI scores were compared with change in Visual analogue scale (VAS) scores. @*Results@#: After SCS, the pain time score improved by 45% (independent t-test, p=0.0002) and the deep pain score improved by 58% (independent t-test, p=0.001). Improvements in the pain time score significantly correlated with improvements in the VAS score (r=0.667, p=0.003, Spearman correlation). Additionally, the morphine milligram equivalent value was markedly lower after vs. before surgery (~49 mg, pared t-test, p=0.002). No preoperative value was associated with clinical outcome. @*Conclusion@#: The NPSI is a useful tool for evaluating the therapeutic effects of SCS. Chronic use of a paddle-type spinal cord stimulation improved the deep pain and the pain time scores.

RESUMEN

Proptosis after a subgaleal hematoma (SGH) is a rare condition that may require immediate intervention to prevent visual loss. A 12-year-old boy presented with localized SGH in the left parietal area after hair-pulling. The SGH was massively expanded on the entire scalp on the 3rd day of the trauma. On the next day after the massive expansion, proptosis of the right eye occurred suddenly. Emergent needle aspiration of the SGH was performed, and the proptosis improved slightly. Fortunately, his vision did not deteriorate. After all, he was diagnosed with coagulation factor IX deficiency (hemophilia B). The supraorbital notch could be a passage of the SGH to extend into the subperiosteal space of the orbit.

RESUMEN

Objective@#A displaced fracture in the anterior cranial base may be complicated by cerebrospinal fluid (CSF) rhinorrhea and enophthalmos. This study introduces a reconstruction technique with direct dural repair and reduction and fixation of the autologous fractured fragments. @*Methods@#Displaced fractures in the anterior cranial base were reconstructed using a stitching-up technique: A bicoronal scalp incision and frontal craniotomy was performed and the displaced bone was withdrawn. The lacerated dura was repaired primarily using a graft.Small holes were created in the intact cranial bones and the displaced harvest bone. Black silk was passed through the holes and the displaced bone was repositioned on tying the silk.Lumbar drain was not placed in any of the cases. The feasibility and outcome were evaluated. @*Results@#Five patients with displaced skull fractures of the anterior cranial base were included. All cases were men who had a direct impact on the forehead and/or eye. All the displaced fractures occurred in the orbital roof, and ethmoid bone fractures were present in 4 cases. Dural laceration was involved in 4 cases and repaired by placing artificial dura in 3 cases and a pericranial graft in 1 case. Following surgery, all cases were uneventful, and the anterior cranial fossa was well reconstructed. CSF leakage or enophthalmos did not occur in any of the cases. @*Conclusion@#Direct dural repair and autologous stitching-up reconstruction using the fractured fragment could be an effective method to prevent CSF leakage and enophthalmos in displaced fractures of the anterior cranial base.

RESUMEN

The incidence of dural venous sinus thrombosis (DVST) and the cerebral venous infarct have not exactly known, but DVST is closely related to the skull fracture around the venous sinus.A 56-year-old man experienced massive watery discharge after hitting on his face by a falling machine. He was alert and no cerebrospinal fluid discharge on admission. Air-density was shown on the jugular fossa in the brain computed tomography. On the 3th day of trauma, he suddenly had dyspnea and loss of consciousness and became comatose. Acute edema on medulla, pons and right cerebellar hemisphere and focal infarct on right medulla were visualized on the brain magnetic resonance imaging. And the sigmoid sinus and the jugular vein were occluded and venous circulation on the right posterior fossa was diminished on the cerebral angiography. Air-density on the sinus may be an indicator into developing venous thrombosis and brainstem venous infarct could be followed by the DVST round the jugular bulb.

RESUMEN

Methods@#The electronic databases MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, and Scopus were searched for relevant articles comparing the outcomes of SB-ACLR versus DB-ACLR that were published until November 2019. @*Results@#Seventeen biomechanical studies were included. The anterior laxity measured using the anterior drawer test showed significantly better results in DB-ACLR when compared with SB-ACLR. In addition, outcomes of the anterior tibial translation test under a simulated pivot shift presented with better results at low flexion and 30° in DB-ACLR, compared with SB-ACLR. However, there were no significant biomechanical differences between the groups in internal rotation. @*Conclusions@#The present study demonstrated that both techniques for ACLR are associated with restoration of normal knee kinematics. DB-ACLR is superior to SB-ACLR in terms of restoration of anteroposterior stability.However, which technique yields better improvement in internal rotation laxity, and internal rotation laxity under a simulated pivot shift at a specific angle, remains unclear.Level of evidence: This is a level II meta-analysis.

RESUMEN

Acute subdural hematoma (ASDH) has been a major part of traumatic brain injury.Intracranial hypertension may be followed by ASDH and brain edema. Regardless of the complicated pathophysiology of ASDH, the extent of primary brain injury underlying the ASDH is the most important factor affecting outcome. Ongoing intracranial pressure (ICP) increasing lead to cerebral perfusion pressure (CPP) decrease and cerebral blood flow (CBF) decreasing occurred by CPP decrease. In additionally, disruption of cerebral autoregulation, vasospasm, decreasing of metabolic demand may lead to CBF decreasing. Various protocols for ICP lowering were introduced in neuro-trauma field. Usage of anti-epileptic drugs (AEDs) for ASDH patients have controversy. AEDs may reduce the risk of early seizure (<7 days), but, does not for late-onset epilepsy. Usage of anticoagulants/antiplatelets is increasing due to life-long medical disease conditions in aging populations. It makes a difficulty to decide the proper management. Tranexamic acid may use to reducing bleeding and reduce ASDH related death rate. Decompressive craniectomy for ASDH can reduce patient's death rate.However, it may be accompanied with surgical risks due to big operation and additional cranioplasty afterwards. If the craniotomy is a sufficient management for the ASDH, endoscopic surgery will be good alternative to a conventional larger craniotomy to evacuate the hematoma. The management plan for the ASDH should be individualized based on age, neurologic status, radiologic findings, and the patient's conditions.

RESUMEN

OBJECTIVE: We introduce innovative method of cervical column reconstruction and performed the reconstruction with a flanged titanium mesh cage (TMC) instead of a plate after anterior corpectomy for cervical spondylotic myelopathy (CSM) and an ossified posterior longitudinal ligament (OPLL).METHODS: Fifty patients with CSM or OPLL who underwent anterior cervical reconstruction with a flanged TMC were investigated retrospectively. Odom’s criteria were used to assess the clinical outcomes. The radiographic evaluation included TMC subsidence, fusion status, and interbody height. Thirty-eight patients underwent single-level and 12 patients underwent two-level corpectomy with a mean follow-up period of 16.8 months.RESULTS: In all, 19 patients (38%) had excellent outcomes and 25 patients (50%) had good outcomes. Two patients (4%) in whom C5 palsy occurred were categorized as poor. The fusion rate at the last follow-up was 98%, and the severe subsidence rate was 34%. No differences in subsidence were observed among Odom’s criteria or between the single-level and two-level corpectomy groups.CONCLUSION: The satisfactory outcomes in this study indicate that the flanged TMC is an effective graft for cervical reconstruction.

RESUMEN

PURPOSE@#The purpose of this study is to review the use of an allograft or autograft in medial patellofemoral ligament (MPFL) reconstruction.@*MATERIALS AND METHODS@#Various electronic databases were searched for relevant articles published from January 2000 to September 2017 that evaluated clinical outcomes of MPFL reconstruction using an autograft or allograft. Data search, extraction, analysis, and quality assessments were performed based on Cochrane Collaboration guidelines.@*RESULTS@#The study of 21 autografts and one allograft was included in this review. Although direct comparative studies were unavailable, the Kujala score and subjective results were reported in the majority of these studies. While the use of an autograft for MPFL reconstruction yielded satisfactory clinical outcomes with few perioperative complications, no new outcome has been drawn from the use of allografts.@*CONCLUSIONS@#Although many studies have shown favorable clinical results for MPFL reconstruction using an autograft, the clinical results of MPFL reconstruction using an allograft have not yet been sufficient to achieve meaningful clinical results due to low levels of evidence. Direct comparisons were not conducted because there were very few studies on allografts; thus, further research in this area should be performed in the future.

RESUMEN

Ossification of the posterior longitudinal ligament (OPLL) can be defined as an ectopic ossification in the tissues of spinal ligament showing a hyperostotic condition. OPLL is developed mostly in the cervical spine and clinical presentations of OPLL are majorly myelopathy and/or radiculopathy, with serious neurological pathology resulting in paralysis of extremities and disturbances of motility lowering the quality of life. OPLL is known to be an idiopathic and multifactorial disease, which genetic factors and non-genetic factors including diet, obesity, physical strain on the posterior longitudinal ligament, age, and diabetes mellitus, are involved into the pathogenesis. Up to now, surgical management by decompressing the spinal cord is regarded as standard treatment for OPLL, although there might be the risk of development of reprogression of ossification. The molecular pathogenesis and efficient therapeutic strategy, especially pharmacotherapy and/or preventive intervention, of OPLL has not been clearly elucidated and suggested. Therefore, in this review, we tried to give an overview to the present research results on OPLL, in order to shed light on the potential pharmacotherapy based on molecular pathophysiologic aspect of OPLL, especially on the genetic/genomic factors involved into the etiology of OPLL.

RESUMEN

Presyrinx consists of reversible spinal cord swelling without frank cavitation, as observed on T2 weighted magnetic resonance imaging (MRI). The condition may evolve into syringomyelia, but timely surgical interventions have achieved meaningful results. Here, we report the case of a 27-year-old woman who presented with headache, dizziness, and diplopia 2 months after suffering a mild head trauma. On MRI, hydrocephalus, downward herniation of the cerebellar tonsil, and a diffuse high signal change in the cervical spinal cord were detected. After insertion of a ventriculoperitoneal shunt, her neurological symptoms resolved, and she has had no signs of presyrinx recurrence for >4 years.

RESUMEN

BACKGROUND: Traumatic spinal cord injury (SCI) is a tragic event that has a major impact on individuals and society as well as the healthcare system. The purpose of this study was to investigate the strength of association between surgical treatment timing and neurological improvement. METHODS: Fifty-six patients with neurological impairment due to traumatic SCI were included in this study. From January 2013 to June 2017, all their medical records were reviewed. Initially, to identify the factors affecting the recovery of neurological deficit after an acute SCI, we performed univariate logistic regression analyses for various variables. Then, we performed a multivariate logistic regression analysis for variables that showed a p-value of < 0.2 in the univariate analyses. The Hosmer-Lemeshow test was used to determine the goodness of fit for the multivariate logistic regression model. RESULTS: In the univariate analysis on the strength of associations between various factors and neurological improvement, the following factors had a p-value of < 0.2: surgical timing (early, < 8 hours; late, 8–24 hours; p = 0.033), completeness of SCI (complete/incomplete; p = 0.033), and smoking (p = 0.095). In the multivariate analysis, only two variables were significant: surgical timing (odds ratio [OR], 0.128; p = 0.004) and completeness of SCI (OR, 9.611; p = 0.009). CONCLUSIONS: Early surgical decompression within 8 hours after traumatic SCI appeared to improve neurological recovery. Furthermore, incomplete SCI was more closely related to favorable neurological improvement than complete SCI. Therefore, we recommend early decompression as an effective treatment for traumatic SCI.

RESUMEN

The rapid spontaneous resolution of an acute epidural hematoma (EDH) has rarely been reported. A possible mechanism of spontaneous resolution is egress of the hematoma into the subgaleal space through a skull fracture. We report a case of rapid redistribution of an acute EDH in a 37-year-old man who had a malignant peripheral nerve sheath tumor of the skull and who slipped and fell when going to the bathroom. A huge EDH without a skull fracture developed in the left parieto-occipital area. The acute EDH was completely alleviated and a newly developed intracerebral hematoma was found on a brain computed tomography scan that was acquired the day after the trauma. Given these findings, a fractured skull and increased pressure in the intradural area may have been the mechanisms underlying the redistribution of the hematoma.

RESUMEN

Traumatic optic neuropathy (TON) is an important cause of severe visual loss after blunt or penetrating head and facial trauma. High-dose steroids and surgical interventions have been applied in the indirect TON. However, there is no convincing evidence that results of the treatment have any strong benefits in terms of improvement of visual acuity. Nevertheless, surgical decompression should be considered in the case of a direct bony compression to the optic nerve and a progressive visual loss in indirect TON. Neurosurgeon should be aware the surgical indication, optimal timing and relevant technique for the optic canal (OC) decompression. In this review article, we will focus on the surgical approaches to the OC and how to decompress it.

RESUMEN

OBJECTIVE: Rapid expansion of subacute subdural hematomas (saSDHs) is an uncommon complication in the course of acute subdural hematomas (SDHs). The current study evaluated relevant factors and treatment methods for saSDHs with neurologic deterioration and mass effect. METHODS: A saSDHs was chronologically defined as an SDH occurring 4 to 21 days after head trauma. All cases of surgically treated SDHs were retrieved from the head trauma bank at our institution. Twenty-three patients with expanding saSDHs who met the following criteria were enrolled in the study: defined age of the hematoma, clinical deterioration, and radiological expansion of the hematoma. Cases were analyzed according to demographic factors, trauma mechanism, medical co-morbidity, and surgical method. RESULTS: Expanding saSDHs occurred more often in older (≥60 years old) than in younger patients (69.6% vs. 30.4%, respectively); they also occurred more often in men than in women (64% vs. 36%, respectively). Antiplatelet or anticoagulant therapy was used in 52% of patients. The Glasgow Coma Scale score was 13 at the time of the trauma and deteriorated to 11 at the time of surgery. The mean time from the trauma to development of the expanding saSDH from an SDH was 13.3 days. Regarding surgical methods, closed-system drainage was performed in 22 patients, and only one patient underwent craniotomy with hematoma removal. All patients exhibited neurological improvements after surgery. CONCLUSION: An expanding saSDH usually occurs around 13 days after trauma in older adults. Minimal trephination with closed-system drainage can be used to manage an expanding saSDHs.

RESUMEN

OBJECTIVE: Protocols for posterior circulation ischemic stroke have not been established by randomized clinical trials. Mechanical endovascular thrombectomy (MET) devices are evolving, and many of these devices already developed or in development are suitable for posterior circulation MET. MATERIALS AND METHODS: We investigated the medical records of patients who underwent MET for posterior circulation ischemic stroke from January 2012 to August 2016. Fifteen patients were included. MET was performed in patients with or without injected intravenous tissue plasminogen activator. MET was considered in patients with a National Institute of Health Stroke Scale score of 4 or more, older than 18 years, with definite occlusion of the basilar artery or posterior cerebral artery (PCA), and who arrived at the hospital within 24 hours from onset. RESULTS: The direct catheter aspiration technique was used in five cases, and the stent retrieval technique was used in seven cases. The stent retrieval technique with the direct aspiration technique was used in three cases. Recanalization failed in two cases. Basilar occlusion without PCA involvement is the only effective factor of successful recanalization (p = 0.03). Successful recanalization (p = 0.005) and the presence of a posterior communicating artery (p = 0.005) affected the good outcome at discharge. CONCLUSION: An early diagnosis and active MET may improve the patient outcome. MET may help recanalization and good flow restoration and the potential for a good outcome.
