RESUMO

Introduction: Glioblastoma represents the most aggressive tumor of the brain with an estimated survival rate of twelve to fifteen months after the primary diagnosis. The role of neurotropic viruses in pathogenesis of the tumor has remained unclear to date. During the last two decades, many studies were conducted with the aim of confirming viral influence in the development of glioblastoma. Methods: We conducted a retrospective study in a time period of five years using formalin-fixed paraffin-embedded tissues of glioblastoma. Immunohistochemistry was performed for three viruses: CMV, EBV and HSV-1, using an automated staining system. Results: Mean age of patients in our group was 66.7±8.5 years. A slight male dominance was noted. Negative immunohistochemistry results were obtained for CMV and EBV, which were excluded from further investigation. Based on IRS score, we confirmed six HSV-1 samples which were rated as IRS score 2. Five more samples of HSV-1 were rated as IRS score 1 and were excluded from the study. Conclusion: According to our retrospective study and its results, we found no impact of neurotropic viruses in the survival rate of glioblastoma. Further studies should be conducted including a wider range of viral detection methods.

RESUMO

Penetrating traumatic brain injury accompanied by perforating ocular injury caused by low-velocity foreign bodies is a life-threatening condition, a surgical emergency and a major challenge in surgical practice, representing a severe subtype of non-missile traumatic brain injury, which is a relatively rare pathology among civilians. Optimal management of such an injury remains controversial, requiring full understanding of its pathophysiology and a multidisciplinary expert approach. Herein, we report a case of penetrating brain and associated perforating eye injury and discuss relevant literature providing further insight into this demanding complex multi-organ injury. We present a case of 39-year-old male patient with transorbital penetrating brain and perforating ocular injury undergoing emergency surgery to remove a retained sharp metallic object from the left parietal lobe. Following appropriate and urgent diagnostics, a decompressive left-sided fronto-temporo-parietal craniectomy was immediately performed. A retained sharp metallic object (a slice of a round saw) was successfully removed, while primary left globe repair and palpebral and fornix reconstruction were performed afterwards by an ophthalmologist. A prophylactic administration of broad-spectrum antibiotics was applied to prevent infectious complications. Early postoperative recovery was uneventful. The patient was discharged on day 45 post-injury having moderate right-sided motor weakness, ipsilateral facial nerve central palsy, and light motoric dysphasia. The vision to his left eye was completely and permanently lost. In conclusion, management of non-missile transorbital penetrating brain injury can be satisfactory when proper clinical and radiologic evaluation, and amply, less radical surgical approach is performed early. A multidisciplinary routine is a prerequisite in achieving a favorable management outcome.

RESUMO

Intraventricular meningiomas are rare and make up between 0.5% and 3% of all intracranial meningiomas, representing one of the most challenging tumors in neurosurgery due to their difficult location. Being initially asymptomatic, such tumors usually attain large size before clinical presentation and diagnostic detection. Available literature concerned with their surgical management remains scarce. Herein, we present a case of microsurgical resection of incidental intraventricular meningioma in a 32-year-old female patient who was admitted to the hospital due to the sudden loss of consciousness, retrograde amnesia, and nausea following a head trauma. Routine brain magnetic resonance imaging revealed an irregular expansive formation located in the occipital horn of the right lateral ventricle showing heterogeneous contrast enhancement. The patient underwent right-side temporal osteoplastic craniotomy with total tumor microsurgical resection followed by external ventricular drainage, and recovered fully afterwards. Histopathologic analysis of tumor tissue samples confirmed the tumor as meningioma WHO grade I. Postoperative brain computed tomography confirmed complete tumor resection. In conclusion, intraventricular meningiomas are rather rare extra-axial tumors and may present with various symptoms depending on their size and difficult location. The development of most modern neuroimaging methods offers the opportunity of their precise and accurate diagnosis, better surgical planning, and favorable outcome. Microsurgical gross resection utilizing intraoperative neuromonitoring and cutting-edge neurosurgical armamentarium remains the treatment of choice for these location-challenging and surgically demanding, predominantly benign intracranial tumors.

RESUMO

OBJECTIVES: This study sought to determine (1) the association between the length of preoperative clopidogrel discontinuation, blood loss, and transfusion requirements and (2) whether preoperative platelet function testing predicts excessive postoperative bleeding in patients undergoing coronary artery bypass grafting (CABG) surgery. METHODS: In this retrospective analysis, patients undergoing CABG were divided into three groups with regard to the period between preoperative clopidogrel cessation and surgery: group 1 (n = 94, ≤3 days), group 2 (n = 100, 4-5 days), and group 3 (n = 83, 6-7 days), respectively. Impedance aggregometry (Multiplate) with arachidonic acid (ASPI) test assay (used for platelets stimulation) and adenosine diphosphate (ADP) test (used for platelets stimulation) was performed before the surgery. Primary outcome was 24 hours chest tube output (CTO) and transfusion requirements (red blood cell concentrate [RBCC], platelet concentrate [PC], fibrinogen concentrate [FC], and fresh-frozen plasma [FFP]) were considered as secondary outcomes. RESULTS: CTO during 24 hours was significantly higher in group 1 as compared with groups 2 and 3, respectively (p = 0.003). Considering secondary outcomes, RBCC (p = 0.043), PC (p = 0.001), FC (p = 0.003), and FFP (p = 0.010) were more frequently transfused in group 1 as compared with groups 2 and 3, respectively. Multiple electrode aggregometry ASPI and ADP tests were significantly correlated with the 24-hour CTO (ASPI test-rho = -0.258, p < 0.001; ADP test-rho = -0.164, p = 0.007). A significant correlation was observed between clopidogrel-free interval and 24-hour CTO (rho = -0.200, p < 0.001). Receiver-operating characteristics (ROC) curve analysis revealed cutoff values to delineate bleeding tendency (ASPI test ≤ 25 area under the aggregation curve [AUC], ADP test ≤63 AUC, and clopidogrel-free interval ≤3 days). CONCLUSION: Excessive postoperative bleeding occurred less frequently if the period between clopidogrel discontinuation and surgery was longer than 3 days, as compared with shorter waiting time. Inadequate recovery of the platelets function following clopidogrel cessation in preoperative period was associated with increased bleeding risk. Platelet function testing was found to be a useful tool for postoperative bleeding management in our hands.

RESUMO

Dysembryoplastic neuroepithelial tumors (DNETs) are benign neoplasms classified in the category of glioneuronal tumors. The estimated incidence of DNETs is 0.03 per 100,000 person per year with the age peak in a range between 10 and 14 years, and decreasing dramatically with increasing age. They are seldom diagnosed in persons above 20 years of age, being a cause of tumor-related intractable epilepsy that begins in childhood or adolescence. They have been proven to be the second most common type of epileptogenic tumors in pediatric population. These rare tumors cause chronic drug-resistant partial complex seizures with or without secondary generalization. Herein, we provide institutional case series of six adult patients with temporal lobe DNET presenting with complex partial seizures. Lesionectomy was performed with tumor resection in toto in three patients. In another three, partial resection was performed, whereas tumor remnant was left intact to avoid possible basal ganglia damage. All patients were seizure free postoperatively. Lesionectomy alone in temporal lobe epilepsy was associated with less favorable outcome than anterior temporal lobectomy. Total tumor removal is considered a major prognostic factor in most studies.

RESUMO

OBJECTIVES: To determine the efficacy of paracetamol and tramadol analgesia via patient controlled pump and intermittent administration using the Short-Form McGill Pain Questionnaire after L4/L5 discectomy in neurosurgical patients. METHODS: Fourteen months prospective quantitative study with 200 neurosurgical patients' participation who underwent elective discectomy of the L4/L5 intervertebral disc extrusion. The study was conducted due to a patient-controlled analgesia pump and intermittent analgesia application. Pain was assessed using the Short-Form McGill Pain Questionnaire in the Croatian language during the zero, first, and second postoperative day. RESULTS: Perception of pain was reduced in patient controlled analgesia pump groups after the second measurement during the first postoperative day [95% CI: -3.89, -0.76], regardless of administered analgesic (p< 0.001). After the final measurement, at 7 PM on the second postoperative day, the differences were not significant (p= 0.070). This study results are registered and allocated in the Australian New Zealand Clinical Trials Registry (ANZCTR). DISCUSSION: Analgesia administration via patient-controlled pump contributes to the alleviation of postoperative pain after L4/L5 disc extrusion surgery regardless of administered analgesic.

RESUMO

Cerebral ventricular system is a sporadic location of intracranial aneurysms including those of basilar artery tip. Treatment of such aneurysms remains challenging regardless of endovascular or microsurgical techniques applied. Basilar tip aneurysm presenting as third ventricular mass is rarely associated with obstructive hydrocephalus, mimicking midbrain expansive process and urging precise diagnostics and prompt treatment. Hence, the management of such patients may be delicate, having an uncertain outcome. We report on a case of a patient with unilateral hydrocephalus caused by large basilar tip aneurysm mimicking a midbrain tumor. We also discuss different operative strategies influencing the outcome, including our own endovascular treatment technical modification. A 62-year-old female patient presented with slightly decreased cognition, minor gait disturbances and urinary incontinence. Computed brain tomography revealed a third ventricle mass with unilateral ventricular dilatation, indicating hypertensive obstructive hydrocephalus. Magnetic resonance and digital subtraction angiography identified the third ventricular mass as a large saccular basilar tip aneurysm. The patient was selected for endovascular treatment followed by cerebrospinal fluid derivation. After aneurysm endovascular occlusion and temporary external ventricular drainage, the symptoms diminished and ventricular dilatation decreased. On post-procedure day 10, the hydrocephalus was relieved and external drainage removed. The patient recovered fully and was discharged without neurological deficit. In conclusion, large basilar tip aneurysms associated with obstructive hydrocephalus are rare and best treated by a combination of endovascular obliteration and cerebrospinal fluid ventricular diversion. The possibility of such an aneurysm should always be considered on the differential diagnosis of cerebral ventricular growths.

RESUMO

BACKGROUND: Glioblastomas are among the most common primary brain tumors with an abysmal prognosis. The significance of glucose metabolism in glioblastoma cell metabolism and proliferation is well-known. However, a significant correlation between the systemic metabolic status of the patient and the cellular proliferation of the glioblastoma has not yet been established. METHODS: Our aim was to observe and analyze for a possible correlation between glioblastoma cellular proliferation and patients' glycated hemoglobin (HbA1c) levels as a marker of chronic systemic glycemia. We analyzed the data from 25 patients and compared their Ki-67 values with their preoperative HbA1c values. RESULTS: We observed a statistically significant correlation (P < 0.03) between chronic glycemia (measured using HbA1c) and the cellular proliferation of glioblastoma (measured by cellular Ki-67 expression). CONCLUSIONS: These results imply a possible positive correlation between glioblastoma cell proliferation and chronic systemic glycemia, a correlation that, to the best of our knowledge, has not yet been reported. Further research in this area could not only lead to a better understanding of glioblastoma but also have significant clinical applications in treating this devastating disease.

RESUMO

Recurrence of intracranial aneurysm after initial microsurgical or endovascular treatment is uncommon. Although the exact etiology remains unknown, recurrent aneurysms may be observed in surgical patients with big and multiple aneurysms, arterial hypertension, non-atherosclerotic cerebrovascular arteriopathies, as well as in those with a familial history of the disease. Such recurrence can occur over a wide period ranging from several months to years after the initial aneurysm treatment. Still, the occurrence delayed by more than 20 years is rather unusual. Herein, we present a case of a 70-year-old female patient who developed late intracranial aneurysm relapse 30 years after successful microsurgical clipping of the middle cerebral artery aneurysm. We also provide a brief review of relevant literature, discussing the etiology and pathophysiology of aneurysm reappearance, as well as different treatment options available. In conclusion, one should always consider the possibility of intracranial aneurysm recurrence regardless of the mode and time of primary surgery. In such a case, a multidisciplinary management approach using flow diverting endovascular techniques is advised in selected patients.

RESUMO

A rare case of thoracolumbar spondyloptosis after a severe polytraumatic event is presented. Spondyloptosis accounts for a minor proportion of all spine trauma cases and is usually accompanied by complete neurological deficit. A 48-year-old man suffered severe polytrauma after having been hit by a truck at the work place. Radiographic scanning revealed multiple traumatic injuries and spondyloptosis at the L1/L2 level in coronal plane. However, despite extensive injuries, ASIA score was estimated as D. The patient underwent urgent multidisciplinary surgery due to severe head injuries. The next surgery was performed to stabilize the thoracolumbar segment and to preserve neurological functions. The surgery included implantation of transpedicular titanium screws via posterior approach. Good postoperative recovery was achieved during early postoperative rehabilitation at our Department, which was estimated as ASIA score D. In conclusion, prompt operative treatment to achieve neural integrity and early rehabilitation should be considered as the gold standard in such complicated injuries. Postoperative recovery largely depends on the quality of rehabilitation, which leads to improvement of patient self-care and normal social and psychological functions. In our case, the good preoperative neurological status of the patient also contributed to better postoperative outcome.

RESUMO

Neoplastic etiology of intracranial cerebral aneurysm is rare. Yet, the risk of its development is higher in malignant tumor patients receiving radiation therapy. Due to the possible negative effects of irradiation on intracranial vessel walls, the risk of aneurysm formation after radiation therapy, which is crucial for some types of breast cancer patients, continues to be a matter of debate. The aim of this study was to evaluate the hazard of multiple intracranial aneurysm development in patients with malignant disease undergoing radiation therapy. It is based on literature review and case report of a 77-year-old female patient who underwent surgery for multifocal invasive hormone-receptor positive ductal breast carcinoma of no special type, followed by chemotherapy, adjuvant radiation and hormone therapy. Her comorbidity included arterial hypertension and type 2 diabetes. Six unruptured intracranial aneurysms of different bilateral locations were diagnosed incidentally by multi-slice computed tomography angiography and digital subtraction angiography of cerebral vessels. Due to the bilateral aneurysm multiplicity, tumor characteristics and prognosis, comorbidity and relatively advanced age, the patient was not selected for active endovascular or microsurgical aneurysm treatment but only periodical clinical, oncologic and radiological follow-up was advised. In conclusion, the risk of multiple intracranial aneurysm formation in patients with breast cancer undergoing radiation therapy is low, but still possible. Long-term follow-up and regular cerebral angiographic check-up studies are necessary in selected malignant patients to decrease such a risk and to evade the worst outcome associated with aneurysm rupture.

RESUMO

Lumbar spine synovial cysts are benign growths adjoining the facet joints that may induce low back pain, lumbar radiculopathy and neurological deficit. However, they are not well defined concerning their origin, cause and pathology, as well as available treatment strategies. The scope of different surgical procedures includes image-guided epidural steroid injection, direct cyst puncture by percutaneous epidural needle, spinal canal decompression and cyst resection, and spinal bone fusion with/without instrumentation. Hereby, we report institutional experience and discuss surgical strategies of lumbar spine synovial cyst treatment. Presenting symptoms, imaging findings and outcomes were retrospectively analyzed in 15 patients with lumbar spine synovial cyst, operated on during a one-year period. The leading presenting symptom was lumbar radicular pain, while the most commonly involved vertebral level was L5-S1. In a great majority of patients, a single-level interlaminectomy and cyst resection were performed. Most patients recovered without postoperative neurological and functional deficit, as well as surgery-related complications. No poor outcome was noticed in our series. Concerning our results and literature review, the optimal management for patients with symptomatic lumbar synovial cyst has to be highly personalized, which is essential to achieve a favorable outcome. Nonetheless, the best treatment strategy has yet to be affirmed.

RESUMO

Nocardia is a ubiquitous microorganism which can be the cause of local and disseminated infection in humans. Immunocompetent and immunocompromised patients both can be affected and Nocardia cyriacigeorgica was reported as a pathogen isolated in patients worldwide. In most cases, nocardiosis is present as pulmonary infection because inhalation is the primary way of bacterial exposure. Nocardial brain abscess occurs usually secondary to a septic focus elsewhere in the body. Considering the facts that the elderly population is growing, such as the number of immunocompromised patients together with high mortality rate in patients with nocardial infection of the central nervous system, we have to raise awareness of the possibility for this rare but potentially fatal condition. We present a case where nocardial abscesses of lung and brain were initially suspected as lung cancer with brain metastases. The patient was treated with a combination of surgical resection and antimicrobial therapy with good outcome.

RESUMO

- Epithelioid hemangioendothelioma is a rare vascular brain tumor. It develops from endothelial cells, usually in the liver, lung, bone and soft tissue. Primary localization of this tumor in the intracranial space is very uncommon; only 47 cases have been described in the literature. This tumor was initially classified as grade I (benign) in the World Health Organization (WHO) 2007 classification. In 2016, this tumor was re-classified as grade III (malignant). Herein, the first case report of epithelioid hemangioendothelioma in the cerebellum of a male patient is presented. Complete surgical excision was done. No adjuvant therapy was administered. Magnetic resonance imaging performed 2 years after the surgery continued to show no recurrence of the tumor. To our knowledge, this is the first report of cerebellar location of this rare tumor. In addition, the authors report drastic re-classification of the epithelioid hemangioendothelioma from the benign tumor (WHO 2007) to a malignant one (2016), which significantly changes postoperative management and follow up of this brain neoplasm.

RESUMO

In patients undergoing coronary artery surgery, improvements in clinical outcomes currently rely on continued refinements of the surgical technique and modulation of adjuvant pharmacotherapy. Despite medical and technological advances, negligible rate of bleeding and ischemic events still persist necessitating further improvements in patient management. Platelet function testing (PFT) might play an important role in meticulous balancing between the risk of bleeding and thrombotic events. A suitable balance can be achieved by implementing a personalized, PFT based approach in antiplatelet therapy (APT) administration/discontinuation management. Despite emerging evidence on the widespread variability in platelet inhibitory response to APT, numerous PFT devices and heterogeneity in reporting study results hamper pooling of the evidence which in turn results with a lack of consensus in "on treatment" platelet reactivity associated with ischemic and bleeding events in perioperative phase. The literature on multiple electrode aggregometry (Multiplate(®); Roche Diagnostics, Mannheim, Germany) in coronary artery disease patients was reviewed systematically. Based on the evidence evaluating the relationship between "drug specific" PFT and bleeding or adverse ischemic events, we sought to define therapeutic window for the most commonly administered antiplatelet drugs such as aspirin (ASPI test) and adenosine-diphosphate receptor blockers (ADP test). Preoperatively, APT administration was primarily focused to avoid bleeding complications. ASPI test value of 20 AUC and ADP test value of <73 AUC were set as cut-off values that delineate bleeding tendency. Postoperatively, "therapeutic window" was set to avoid both bleeding and adverse ischemic events. Therapeutic ranges were as follows: 20 AUC < ASPItest ≤ 30 AUC and 19AUC < ADP ≤ 46AUC, respectively. This is the first attempt to define PFT based "therapeutic window" according to, perioperative APT administration/discontinuation management would be targeted. It seems that the "one-size-fits-all" concept of perioperative APT administration management is outdated and further development of PFT based, personalized APT administration/discontinuation management is desirable. This concept therefore presents a possible step forward in patient care and provides a platform for further interventional trials whereby the impact of its application on clinical outcomes would be validated.

RESUMO

OBJECTIVE: The aim of our study was to assess the prevalence and characteristics of nutritional risk in patients scheduled for cardiovascular rehabilitation. BACKGROUND: Knowledge concerning nutritional aspects of cardiovascular diseases is contemporary limited. METHODS: Nutritional risk screening using a standardized Nutritional Risk Screening-2002 (NRS-2002) questionnaire was performed on a cohort of consecutive patients scheduled for rehabilitation 1-6 months after treatment for ischemic, valvular, or combined causes of heart diseases. Baseline weight was available for more than 80% of patients. RESULTS: The study population consisted of 317 patients, aged 23-85 years, with a mean age of 62.5 ± 11.3 years. Male to female share was 253 (79.8%) and 64 (20.2%), respectively. Twenty-eight (8.8%) were treated for myocardial infarction conservatively, 151 (47.6%) by percutaneous coronary interventions, and 145 (45.7%) by surgery. NRS-2002 was 3.56 ± 1.54 in range 0-6. A high correlation was found between the NRS-2002 and percentage weight loss history (rho = 0.813; p <0.001). Significant differences according to increased nutritional risk (NRS-2002 ≥ 3) were found within age groups (p < 0.001), disease etiology (p = 0.002), cardiovascular treatments (p < 0.001), and grades of renal function (p < 0.001). Odds for developing increased nutritional risk (NRS-2002 ≥ 3) were significant for cardiovascular treatments (odds ratio [OR] = 4.35, 95% confidence interval [CI], 2.28-8.30, p < 0.001), age (OR = 3.19, 95% CI, 2.00-5.09, p < 0.001), grade of renal function (OR = 1.91, 95% CI, 1.17-3.09, p = 0.009), diabetes mellitus (OR = 2.37, 95% CI, 1.09-5.16, p = 0.029), and any psychological disturbance (OR = 2.04, 95% CI, 1.06-3.90, p = 0.032). CONCLUSIONS: Pronounced nutritional risk frequently existed among patients at stationary cardiovascular rehabilitation. Nutritional risk was connected with preceding cardiovascular treatments, patient age, and renal function. Further studies concerning nutritional risk and its connections with clinical outcomes might serve as a resourceful perspective to improve outcomes or quality of care for the entities from the cardiovascular diseases continuum.

The aim of this study was to determine the public's, i.e. citizens' attitude on one hand, and health-care professionals' attitude on the other, regarding the public education in palliative care. Also, the assessment of health-care professionals' attitude regarding the need to establish a sub-specialty in palliative medicine in Croatia was performed. The study was carried out during 2007 and 2008 in the capitals of 7 Croatian counties, involving 2353 participants. Two types of anonymous questionnaire were distributed. Citizens were surveyed at public places, business offices, waiting rooms, while health-care professionals were surveyed in medical centers. The survey was conducted personally by the authors, i.e. "face to face" with the respondents. The collected data were entered into a database and analyzed, taking into account the anonymity, privacy and data confidentiality. The response rate was 99% for the public and 97% for health-care professionals. 44% of the public thought that educating the public in palliative care is absolutely necessary, and 42% that it is mostly necessary; compared with 47% of health-care professionals who thought education was absolutely necessary, and 45% who thought it is mostly necessary. In addition, health-care professionals were asked about their opinion regarding the establishment of a sub-specialty in palliative medicine and 76% of respondents considered it absolutely necessary. Both the public and health-care professionals recognize the need for public education in palliative care. The authors wish to especially emphasize health-care professionals' perception of a great need for the establishment of an official medical curriculum and a medical sub-specialty in palliative medicine.
