RESUMEN

INTRODUCTION: Among children who sustain mild traumatic brain injury (mTBI), 10-30% develop a cluster of cognitive, physical, and emotional symptoms commonly referred to as post-concussion syndrome (PCS). Symptoms typically resolve within 7-10 days, but a minority of patients report symptoms that persist for months or even years. The aim of our study was to identify a neurobiochemical marker after mTBI that can predict the presence of post-concussion syndrome three months after head injury in paediatric patients. MATERIALS AND METHODS: Children between 7 and 16 years of age who had head trauma and no other complaints were included. Three months after the initial visit, participants or parents/guardians were interviewed in person about the children's PCS symptoms using the Rivermead Post-Concussion Symptoms Questionnaire (RPQ). RESULTS: The mean value of S100B protein in serum in 38 patients without signs of PCS was 0.266 µg L-1, with a 95% confidence interval (CI) of 0.221 - 0.310 µg L-1. Among the 22 patients with signs of PCS, the mean value of S100B protein in serum was 0.845 µg L-1, with a 95% CI of 0.745-0.945 µg L-1. Patients with signs of PCS had higher S100B protein levels than those without signs of PCS (p < 0.0001). CONCLUSIONS: Our prospective study showed that S100B protein is a useful neurobiomarker for detecting paediatric patients at risk for post-concussion syndrome. We found that the biomarker S100B correlated with the severity of traumatic brain injury (number of lesions on CT) and the presence of post-concussion syndrome.

RESUMEN

INTRODUCTION: Traumatic brain injuries (TBIs) are very common in paediatric populations, in which they are also a leading cause of death. Computed tomography (CT) overuse in these populations results in ionization radiation exposure, which can lead to lethal malignancies. The aims of this study were to investigate the accuracy of serum S100B levels with respect to the detection of cranial injury in children with mild TBI and to determine whether decisions regarding the performance of CT can be made based on biomarker levels alone. MATERIALS AND METHODS: This was a single-center prospective cohort study that was carried out from December 2016 to December 2017. A total of 80 children with mild TBI who met the inclusion criteria were included in the study. The patients were between 2 and 16 years of age. We determined S100B protein levels and performed head CTs in all the patients. RESULTS: Patients with cranial injury, as detected by CT, had higher S100B protein levels than those without cranial injury (p < 0.0001). We found that patients with cranial injury (head CT+) had higher mean S100B protein levels (0.527 µg L-1, 95% confidence interval (CI) 0.447-0.607 µg L-1) than did patients without cranial injury (head CT-) (0.145 µg L-1, 95% CI 0.138-0.152 µg L-1). Receiver operating characteristic (ROC) curve analysis clearly showed that S100B protein levels differed between patients with and without cranial injury at 3 hours after TBI (AUC = 0.893, 95% CI 0.786-0.987, p = 0.0001). CONCLUSION: Serum S100B levels cannot replace clinical examinations or CT as tools for identifying paediatric patients with mild head injury; however, serum S100B levels can be used to identify low-risk patients to prevent such patients from being exposed to radiation unnecessarily.

RESUMEN

Meningioma accounts for 15% to 20% of all intracranial neoplasms. Intracranial meningioma is a common brain tumor but huge meningiomas with extracranial extensions are extremely rare. Various symptoms, including neurological deficits and epileptic seizures are very frequent in these cases. Surgery still remains the principal form of the treatment and must be preceded by appropriate preoperative diagnostics. We report an unusual case of a huge meningioma of the brain (intracranial-extracranial extension) invading and destroying the skull bone and subcutaneous and cutaneous tissue. A 44-year old man in otherwise good general health was admitted to our University Neurosurgical Clinic. The MRI revealed an intracranial-extracranial lesion invading the skull bone, subcutaneous and cutaneous tissue. The tumour was removed by microsurgery. The bone was found to be predominantly lytic, and dura was infiltrated by the tumor. The bone and the dura were completely removed together with the entire tumor. Such cases are very rarely seen these days because of modern radiology techniques A giant intracranial-extracranial meningioma is therefore very unusual. Radiotherapy is generally recommended for incompletely resected meningioma and malignant meningioma.

RESUMEN

BACKGROUND: Chronic subdural hematoma (CSDH) is frequent pathology in neurosurgical practice. The aim of this study is to present the first series of patients with CSDH, who got surgically treated in Clinic of Neurosurgery, University Clinical Center of Kosovo. MATERIALS AND METHODS: This is a retrospective study that included 137 patients with CSDH who had been treated during the period 2008-2012. The data were collected and analyzed from the archives and protocols of the University Clinical Center of Kosovo. Patients were analyzed in many aspects such as age, gender, etiological factors, clinical features, localization, diagnoses, methods of surgical interventions, recurrences and mortality of patients. RESULTS: From 137 patients with CSDH, 106 (77.3%) were males and 31 (22.7%) females. Average age of patients was 62.85 years. Analyzed according to the decades, the highest number of causes with CSDH was between 70 and 79 years (46%). The head trauma has been responsible for CSDH in 88 patients (64.3%), while the main symptom was headache (92 patients or 67.1%). One burr-hole trepanation with closed drainage system has been used in majority of cases (in 101 patients or 73.7%). The recurrence of CSDH was 6.5%, whereas mortality 2.9%. CONCLUSION: CSDH is more common in elderly patients. The male-female ratio is 3.4:1. Like other authors we also think that treatment with one burr-hole and drainage is a method of choice, because of its simplicity and safety.

RESUMEN

Typical dermoid cysts are well-circumscribed fat-density masses with no associated contrast enhancement; rarely, they may appear hyperattenuating on CT scan. CT hyperattenuating dermoid cyst (CHADC) is very uncommon, with only nine case reports in the literature update, which occurs exclusively in the posterior fossa. CHADC with mural nodule is extremely rare and, to the best of our knowledge, only two cases have been documented previously in the literature. A 49-year-old farmer had a 2-month history of occipital headaches, which were not suggestive of raised intracranial pressure. During the last month, he experienced loss of balance, frequent falls, anorexia and loss of weight. Magnetic resonance imaging (MRI) showed a huge mass from the tentorium to the foramen occipitale magnum with obliteration of the fourth ventricle; the lesion was well circumscribed. We completely removed the tumor and postoperative MRI showed no residual tumor. Epidermoid tumors with enhancing mural nodule on MRI and with hyperattenuating lesion on CT are extremely rare. Dermoid cysts are never associated with edema and extremely rarely cause obstructive hydrocephalus. MRI investigations are mandatory to diagnose these cases. The best curative treatment is total removal of the lesion.

RESUMEN

INTRODUCTION: Shunting a hydrocephalus is among the most commonly performed neurosurgical procedures. Hydrocephalus constitute a significant medical problem in terms of urgency and treatment. Shunting of cerebrospinal fluid has dramatically reduced the morbidity and mortality of hydrocephalus, but they have potential complications that may need multiple surgical procedures during a patient's lifespan. MATERIALS AND METHODS: We evaluated the following individual characteristics in relation to shunt complication rates: sex, ethnicity, age at the time of the first shunt placement (1 month [neonate], 1 to 12 months [infant], 1 to 18 years [child], 18 years [adult]), hydrocephalus type (spina bifida, congenital excluding spina bifida, communicating, obstructive) and socioeconomic status. In this retrospective study 193 patients were analyzed, unfortunately 27 where lost in the procedure of follow up and 12 died this patients were excluded from studies. RESULTS: Obstructive hydrocephalus (47.9%) was the most common diagnosis followed by communicating hydrocephalus (13.3%). Patients with ventriculoperitoneal shunt that were followed over time in 37% of cases experienced at least one surgical shunt complication during the study period and 13% of patients had multiple shunt complications. DISCUSSION: The causes for shunt malfunction include shunt infection, obstruction, distal catheter migration, shunt disconnection etc. Neonates and children experienced the highest complication rates. By 5 years of follow-up almost half of the children required a repeat surgical procedure. Children with obstructive hydrocephalus experienced the greatest risk of needing an initial shunt revision. CONCLUSION: Ventriculoperitoneal shunts constitute a significant medical problem, in terms of both urgency of treatment and economic costs. In conclusion, young infants are at highest risk for CSF shunt revision.

RESUMEN

BACKGROUND: The study is to show the advantages of preservation of a calvarial bone flap in the abdominal pocket after decompressive craniotomy. Decompressive craniectomy is an option in the surgical management of refractory hypertension when maximal medical treatment (sedation, drainage of cerebrospinal fluid, moderate cooling, etc) has failed to control refractory high intracranial pressure. METHODS: We have prospectively analyzed 82 consecutively operated cases decompressive craniotomies done at the University Neurosurgical Clinic in Prishtina/KOSOVA over a period of eight years (June 1999 to Aug 2008). Of the 75 who had their grafts replaced (7 patient died before replacement of bone graft), 62 patients had hemicraniectomy (fronto-parieto-temporal) 7 of them were bilateral. RESULTS: In 66 out of 75 patients was achieved a satisfactory and cosmetically reconstruction, in 9 cases was required augmentation with methyl methacrylate to achieve cosmetic needs. Two patients had infection and the bone was removed; 6 months later these patients had cranioplasty with methyl methacrylate. The duration of storage of calvarial bone in abdominal pouch before reimplantation was 14 - 232 days (range 56 days). CONCLUSION: We think that storage of the patients own bone flap in the abdominal pocket is a safe, easy, cheap, sterile, histocompatible, and better cosmetic results.

RESUMEN

INTRODUCTION: In the present study we report 36 cases of anterior encephaloceles treated at Clinic of Neurosurgery in the University Clinical Center of Kosova over a 24 year period. MATERIALS AND METHODS: All 36 children were included in this retrospective study (1986 through 2009). Their ages ranged from 1 day to 10 years (mean 13 months); 20 were boys and 16 were girls. The commonest type of anomaly seen was nasofrontal 17 patients, 12 nasoethmoidal, and 7 nasoorbital. The size of the lesion varied from 2.5 cm to 28 cm. Hypertelorism occurred in 12 patients. Hydrocephalus was present in 11 patients and in 8 of them was progressive. RESULTS: 1 patient died on 10th postoperative day due to fulminant meningitis. Cosmetic results were judged from parents as excellent in 16 patients, good in 12 patients, average in 6 patients and poor in 2 patients. None of patients were lost to follow-up. DISCUSSION: Histologic examination of the herniated tissue can vary between normal brain to fibrous atrophic nonviable tissue. No familial cases have been reported in the literature, we also have similar experience. In our study we have found that the prevalence is higher among patients coming from rural parts of our country with pore living conditions, malnutrition and so on. We have avoided surgery in very young children until body weight is around 5-6 kg because of complication from blood lose and hypothermia. CONCLUSION: The aim of treatment is early removal of the meningoencephalocele to allow normal growth forces to be re-established. In patients with hypertelorism, correction surgery is done in the same session. Ifhydrocephalus is not treated before corrective surgery for encephalocele, the risk of postoperative CSF is very high. With one stage surgery excellent results can be achieved.
