However, data on complications coming with this new technique in children suffering from craniosynostoses are scarce and have only been assessed retrospectively so far. It has been the aim of the present study to prospectively follow up children undergoing craniosynostosis surgery with a focus on complications related to UARPO materials. Ten pediatric patients (3 female/7 male) were operated due to craniosynostosis at an average age of 9.1±3.8 months using UARPO (SonicWeld/Resorb-X, KLS Martin, Tuttlingen, Germany). Clini...

We found significant association between the presence of HAIs and worse clinical outcomes, higher costs, and longer length of stay. The pathogens responsible and infection locations were similar to existing series in the literature. Although variability in study designs in the literature makes interpretation and comparison of results difficult, measures to prevent these complications.

While the association bet¬ween cavernous angioma with gliomatous lesions is even more rare, it is considered by certain authors to be a particular pathological entity termed angioglioma. The authors report on two cases of association of a cavernous angioma with a ganglioglioma and an oligodendroglioma respectively. Subsequent review of the literature on the so-called angiogliomas was conducted. In the author's opinion, the entity of angiogliomas represents a gene¬ral spectrum of angiomatous neoplasms that include gliomatous tumors, in the majority low-grade gliomas, associated with a major vascular component. ...

A 53 year-old man presented with severe headache, limitation of upward gaze and diplopia. The patient's neurological examination was unremarkable. Magnetic resonance imaging (MRI) scans of the brain demonstrated a 1.5 x 2 cm well demarcated solitary mass in the pineal region with hydrocephalus. Surgery was performed and adenocarcinoma was diagnosed. A systemic investigation revealed adenocarcinoma of the lung as primary lesion. Although rare, metastatic tumor should be considered in the differential diagnosis of pineal region tumors. PMID: 22167289 [PubMed - in process] (Source: Neurocirugia...

The implant is built in titanium and coated with plasmapore (a sort of pure titanium powder). Bone growing through titanium microstructure is induced by the plasmapore, and fusion is progressively obtained once this boneinduction is completed. From January 2002 to December 2008 we operated upon 104 patients employing this implant at one or two cervical spine levels. The more frequent condition was radiculopathy caused by disc herniation or spondilosis (N= 85; 81.7%), followed by mielopathy (N=13; 12.5%). Six cases (5.7%) corresponded to cervical fractures or dislocations. In these latter ones Ce...

When these drugs reduce the size of invasive prolactinomas, the intra- and extra-cranial spaces may be communicated. Pneumocephalus and cerebrospinal fluid leakage have been reported. A 56 year old male was admitted to the emergency unit with an intracranial hypertension syndrome. He had been treated for 2 weeks with cabergoline after an invasive prolactinoma was discovered. Brain CT showed frontal interhemispheric pneumocephalus on the previous tumor cavity, and bony defect on the sellar floor.

In patients with a family history of Von Hippel Lindau disease and clinical symptoms of vertigo and normal hearing or with slight hearing loss we should suspect the presence of endolymphatic sac tumor. The clinical presentation of hearing loss can be sudden and irreversible even with negative or inconclu¬sive images. Therefore, a quick action is important for the preservation of this function.

In a cervical spine MR a Chiari I malformation with syringomyelia from C1 to T2 was found, which was treated by foramen magnum decompression, dural plasty and removal of the posterior arch of the atlas. A discussion of the embryological mechanisms that might be involved in the coexistence of these two enti-ties is presented, emphasizing the role of para-axial mesoderm.

Most of the papers in the literature discuss the behaviour of the reinforcement material inside a bony environment, but they do not refer to the evolution of the cement outside the vertebral space. We have appreciated in our case that the leaked cement is not being substituted for bone but it suffers a process of progressive resorption. The extravasation of the vertebral reinforcement material is an important and potentially serious complication of the vertebral augmentation techniques. To avoid this, a very precise chirurgical technique is necessary, under radiological guidance. Biocompatibility, biodegradability and osteoconductivity are the main advantages of biological cemnets. We base the choice of the cement on the balloom/trabeculae interaction. PMID: 22167291 [PubM...

When the hystopathological diagnosis of ENB is considered, the Hyams classification can be valid considering grade IV as an advanced stage that is sometimes difficult to differentiate from other undiferentiated tumors. The subcranial approach or craneofacial resection in advanced stages (Kadish C and some B) should be considered as the first treatment of choice. Radiotherapy is indicated in all cases and chemotherapy in selected cases. Hyams' classification was the only staging system that proved useful as a prognostic factor in our series.

Endoscopic management of intraventricular and/or periventricular brain tumors is effective, and allow diagnostic biopsy and simultaneous treatment of the associated hydrocephalus in many cases. So, it could be the treatment of choice in those tumors that are not suitable for microsurgical resection. Although this technique is not exempt of serious complications, morbimortality could be lower than conventional microsurgical approach.

It is interesting, in the differential diagnosis, to bear in mind the possibility of ectopic relapse of craniopharyngioma in patients who have been operated because of this type of tumor and who present a new mass in nervous central system (CNS). In view of the long time of latency that can pass between the resection of a craniopharyngioma and his relapse, there becomes necessary a long follow-up of these patients by periodic imaging tests.

Leptomeningeal spread is a rare phenomenon and when it happens usually doesn't change the primary tumor's behavior. In our case the aggressivenes could be explained by a potential malignization of the primary tumor that it wasn't documented because of the partial resectionss from the lasts surgeries or instead the tumor was actually a monomorphous pilomyxoid tumor.

The true significance of the ID remains unknown, but in some instances it is necessary to consider its management: 1. In patients with ruptured aneurysms submited to microsurgical clipping and with an ipsilateral ID, the lesion must be explored and treated; 2. In patients with ruptured aneurysms treated with endovascular procedures or harbouring an ID contralateral to a microsurgically treated aneurysm, the microsurgical indication will be done after considering all risk factors; 3. In patients with SAH and an ID as the only potential source of the bleeding there would be an indication for microsurgical exploration; 4. The incidental finding of an ID should be indication for observation in absence of major risk factors. PMID: 21858404 [PubMed - as supplied by publisher] (S...

Often symptoms, physical examination and radiology are not enough to set a diagnosis. ICP continuous monitoring is a safe and reliable tool that provides valuable information about CSF dynamics in these patients. Not only quantitative analysis is needed but also a qualitative one that enables pathological waves identification, because high amplitude B waves are strongly related to shunt dysfunction. In this paper experience about ICP continuous monitoring in patients with shunt dysfunction suspect is presented. Quantitative and qualitative data analysis led to a correct diagnosis, improving all the patients ...

Peroneal nerve is the most affected nerve. The entity is rare and its ethiopathology still remains to be definitely elucidated. In 2003 Spinner et al published their articular theory, implicated in the formation and frequent recurrence of these lesions after surgical treatment. The practical application of this theory, nowadays almost universally accepted, generated an important diminution in the recurrence rate after surgical evacuation of this lesions, previously very elevated. Most of the cases of this entity are des...

Nowadays, trend is to perform surgery in patients with spinal hematoma and significant neurological deterioration during the first hours. However, good neurological outcomes can be achieved with conservative management, in well selected patients with non progressive, incomplete and partial deficits. Presently, we can not predict wich is the best treatment for each case.

P. acnes is a gram-positive anaerobic organism which is part of the saprophytic flora of the skin and others parts of the body. However, it can cause infections, as in the central nervous system, especially post-surgical infections in which can be the second more frequent organism after Staphylococcus aureus. P. acnes grows slowly and shows better growth in liquid anaerobic media. It is usually resistant to metronidazol and sensitive to penicillin. In postoperative central nervous system infections we must take into account the possibility of this organism, process the sample properly and keep touch with the Microbiology ...

Intraoperative electrical cortical stimulation is useful to identify the SMA. Once identified, SMA preservation decreases the risk of postoperative symptoms and permanent SMA syndrome. When SMA is infiltrated by the tumor, radical resection may cause permanent neurological deficits, specially in the dominant hemisphere.

In our experience the bifrontal approach allowed the radical removal of huge olfactory groove meningiomas. The microdissection of the anterior cerebral artery A2 segments is possible thanks to the arachnoidal plane between vessels and tumor. Tumoral blood flow is secured by the early approaching of the base of the tumor and preoperative embolization is not necessary. Bifrontal approach allows an aggressive treatment of the hyperostosis, bone infiltration and paranasal sinus invasion. Anterior fossa reconstruction is done using a vascularized periosteal flap.

Ureter injury in posterior lumbar spine surgery can happen due to its close anatomical relationship with the vertebral body and disc. L4-L5 is the level most often affected. Due to the fact the ureter is surrounded by retroperitoneal fat, injury is less likely to happen and thus the low number of documented cases. Although the initial symptomatology may be inespecific, an early diagnosis is essential in order to avoid further complications such as a sepsis or a kidney loss. There are several treatment options although the most often used is the end to end anastomosis specially if there is a complete ureter injury.

The integration of preoperative and intraoperative anatomic and functional studies allows a safe functional resection of the brain tumors located in eloquent areas, compared to the tumoral resection based on anatomic imaging studies. Multimodal navigation allows the integration and correlation among preoperative and intraoperative anatomic and functional data. Cortical motor functional areas are anatomically and functionally located preoperatively thanks to MRI and fMRI and subcortical motor pathways with TDI and tractography. Intraoperative confirmation is done with CS and N20 inversion wave for cortical structures and with sCS for subcortical pathways. With this protocol we achieved a mean of 90% of volumetric resection in cortical and subcortical tumors located in eloquent ...

The preoperative diagnosis of these neoplasms is difficult because the clinical suspicion is low in supratentorial location. Imaging techniques are useful but definitive diagnosis is made through pathologic examination. The use of immunohistochemical techniques is helpful for the differential diagnosis with lesions that are more common in this region. The importance of a correct diagnosis of these histologically benign tumors, lies on the possible association with VHL syndrome and its complications.

Increased lactate and LPI were frequent findings after acute TBI and in most cases they were not related to episodes of brain tissue hypoxia. Furthermore, the concordance between both biomarkers to classify metabolic dysfunction was weak. LPI and lactate should not be used indistinctly in everyday clinical practice because of the weak correlation between these two markers, the difficulty in their interpretation and the heterogeneous and complex nature of the pathophysiology. Other differential diagnoses apart from tissue hypoxia should always be considered when high lactate and/or LPI are detected in the acute injured brain.

After replacement of a CSF shunt, the intracranial pressure returned to normal and the hypophysis filled up again all the sellar fossa. We discuss the possibility of the involvement by an ischemic atrophy of the adenohypophysis in the development of a primary empty sella with idiopathic chronic raised intracranial pressure that prevents the recovery of the gland volume after restoring the intracranial pressure to normal values. Restitution of empty sella may be an indicator of normal intracranial pressure in these cases.

Diagnosis was done using neuroimaging (CT scan, angio-CT-3D, angio-MRI, angiography) but patients with ruptured aneurysms were treated with the sole information provided by the angio-CT-3D. The average fundus size was 8.4mm (3-13.3) and the average neck size was 6.8mm (3-9.6), being the fundus-to-neck ratio 1.32 (0.46-2.05). All lesions were microsurgically treated through a pterional approach with the help of temporary clipping of the ...

Early tracheostomy (</= 9 days) provides significant advantages in neurocritically ill patients: it shortens length of mechanical ventilation and ICU stay and decreases antibiotic and sedatives requirements. Although later tracheostomy is not directly related with mortality, it increases considerably the risk of suffering from pneumonia, particularly in patients with TBI. These clinical circumstances should be evaluated individually in each patient, so the best time to perform tracheostomy in neurocritically ill patients could be established.

Patients with AC, especially when these are located in temporal fossa, appear to harbour a life-long risk of contracting subdural hematoma. Hematoma evacuation is adequate at first operation and if arachnoid cyst is symptomatic or preoperative symptoms persist, additional arachnoid cyst surgery should be considered.

Puncture of the sac represents a quicker and more convenient way to obtain CSF in myelomeningocele cases. In addition, there was no increase in pain to a level that would cause stress for the baby. A CSF sample can be taken from the sac for diagnosis of CNS infection in myelomeningocele patients. This method, therefore, represents a safer and more comfortable option for both the patient and doctor.

They are very rare and account for 0.3 to 1.5 % of all spinal schwannomas. It is not known for certain why this happens, and several theories have been put forward. They do not exhibit any characteristic clinical picture, being pain the most frequent symptom. Imaging is also not specific and the correct diagnosis is attained most of the times after pathological examination. The goal of treatment must be complete removal, which is curative.

Disc herniation can regress, or even disappear, in a number of patients, rendering the radiological findings not to be taken as the only surgical indication criterium. We consider that the best treatment is the one relying on a good doctor-patient relationship, sustented in a balance between conservative and surgical treatment. According to clinical data, the first one (conservative) should not exceed the estimated time beyond which the surgical result would be insatisfactory. The seconde one (operative), excepting "need-tooperate" situations (such as cauda equina compression, progressive or serious motor déficit, or unbearable pain), should be prudently supedited to MRI regresión control, in particular in patients in which a clinical improvement is observed.

Different techniques have been used in craneofacial surgery for the reconstruction of great osseous defects in pediatric patients for many years. This paper is about a new technique to obtain osseous graft for covering osseous cranial defects, using particulate bone, harvested from the patient calvarian using a hand-driven brace and covered with a fibrin adhesive. This is a very simple technique, which provides a great amount of bone from the patient himself, therefore producing a small morbidity. Since 2007 the authors have been using autologous par...

Intraoperative visual inspection confirmed that the ophthalmic artery was left intact. She had no light perception on the operated side right after surgery. Angiography one week after surgery confirmed exclusion of the aneurysm, no filling of the proximal portion of the ophthalmic artery, and a very faint filling of its distal orbital part. She gradually recovered from this deficit and 9 months after surgery she is capable of counting fingers.

It is wise to invest time to deal with patients, including the verbal informed consent, which must be confirmed by the written informed consent form. It is also important to leave a written proof of medical praxis, both related to surgical records and to diagnosis and follow-up of the patient. Procedures with a lower life-threatening risk should not be underestimated, since they comprise the greatest demanded group. The greatest amount of demands is related to economic reimbursement, especially in private practice.

The best results were obtained in patients with isolated craniosynostosis and the worst in cases with syndromic and multi-suture craniosynostosis. The rate and severity of complications were related to the type of surgical procedure and was higher among patients undergoing re-operations. The mean time of hospitalization was also modified by these factors. Finally, we report our considerations for the management of craniosynostosis taking into account each specific technique and the age at surgery, complication rates and the results of the whole series.

Real-time 2-D ultrasonography affords an adequate image quality for performing guided-craniotomy in supratentorial brain tumours, as it allows for a safe and accurate localization of the lesions. Its use is mainly indicated in the removal of tumours located in, or close to, important anatomical and functional brain areas and to depict the presence of tumour rests after surgical removal of cerebral neoplasms.

Kyphoplasty could constitute an alternative and/or complementary treatment of traditional spinal stabilization-fusion procedures in non osteoporotic vertebral fractures. Therefore, it should be offered, when indicated, as a substantial possible part of the treatment, to the patients suffering from vertebral fractures. Additional advantages of combining kyphoplasty and posterior fusion are the possibility of reducing the number of fused levels (shorter instrumentations), and to perform a 360 degree stabilization-remodeling through a single posterior approach.

We diagnosed and treated a total of 42 patients between 1988 and 2006; 36 of them were operated with partial resection in most cases. Brain-stem tumors constitute a rare condition with very bad prognosis. A surgical complete resection of the mass is not possible in most cases, so the principal surgical objetive is reduction and descompression. The best prognosis is seen in patients with low grade tumors with minimal neurologic deficit. Most of these tumors cause death in a short period, usually one year or less.

Syringes are caused by obstructions of CSF pathways of different causes. If we can not find a cause responsible for the blockage, we called it "idiopathic" syringomyelia. Drainage procedures have been widely used but results, especially long-term results, are not favourable and complication rate is high.

A yellowish mass was observed in the frontal lobe. The content of the cyst consisted of old hematoma, xanthochromic fluid and necrotic tissue, was evacuated and the cyst wall was totally resected. No abnormal pigmentation was noted in the cyst wall and surrounding brain tissue. The imaging features of metastatic melanomas are distinctive due to the presence of melanin and the propensity for hemorrhage. Both hemorrhage and melanin can produce T1-weighted hyperintensity and T2-weighted signal intensity loss. PMID: 18726049 [PubMed - as supplied by publisher] (Source: Neuro...

Though different studies have shown contradictory results on the possible effects of reduced-hour work week on both patients, safety and resident learning, a great concern is arising in Europe and Japan where duty-hour restriction is much more drastic than in USA (48 and 40 hours vs 80 hours, respectively). Deterioration of residents, training could also diminish the total time dedicated to and quality of medical student education.

Ibn Sina (known as Avicenna in the West), who was among the leading figures during medieval ages and influenced the upcoming periods in the Eastern and Western hemispheres for long time, focused also on these crucial problems. In his principal medical work, the Canon of Medicine, Avicenna underlined the significance of wry mouth-related disorders and wrote a precise chapter over this topic with the heading "Laqve." However, the term "laqve" is usually accepted only as facial paralysis in most of historical texts. Further detailed analysis of the text reveals that, all the abovement...

The aim of this study was to review the existing evidence supporting surgical evacuation of the haematoma in this pathology. Without any clinical trial on this field, data derived from clinical series suggest that the level of consciousness, the size of the haematoma, the presence of hydrocephalus and the compression of the posterior fossa CSF containing spaces are the main criteria to decide management. Fourth ventricular compression seems to be the best indicator of the last parameter. Existing bibliography shows tha...

This early change in SpO2 may be either due to the facial mask or the operational stress. Since a very small decrease in saturation at this level, reflects a large decrease in PaO2, our findings may have a clinical value for the health workers and the surgeons.

The inter-relationship between the brain and the computer (brain-machine interface) has already occurred and has been applied in the field of neuroprosthetics and deep brain stimulation.
