Falls and Motor Vehicle Accidents as The Most Common Causes of Moderate and Severe Head Injuries in Children Age 3 and Younger

Objective: We aimed to evaluate the most common causes of moderate and severe head injury at age 3 and younger.Material and Methods: This is a retrospective study that included 157 children (105 males and 52 females) at 3 years of age or younger who were admitted to our emergency unit for moderate or severe head injury between June 2001 and December 2008. Data on patient age, gender, cause of trauma, clinical signs and symptoms, length of hospitalization, radiological findings, surgery, additional injuries, postoperative and late complications, and mortality were examined.Results: The mean age of the patients was 21.05 months. The most common presentation was deterioration in consciousness. The most common cause of moderate head injury was a fall from 1–2 m at 7–12 months of age, and for severe head injury it was a motor vehicle accident at 19–24 months of age. The most common radiological finding in all groups was a linear fracture. In the moderate head injury group, 16 epidural hematomas (EDH), four subdural hematomas (SDH), two dura-brain lacerations, and two depressed fractures required surgery. In the severe head injury group, 6 SDHs and 5 EDHs required surgery. The major postoperative complications were meningitis, rhinorrhea, epileptic seizures, and subdural fluid collection. The overall mortality rate was 3.18% (5 of 157 patients).Conclusions:In our series of moderate and severe head trauma in patients younger than 3 years, the most common cause of trauma was falling from 1–2 m. For prevention, family caregivers must watch crawlers and toddlers closely

Evaluation of the Lateral Wall of the Nasal Cavity in Relation to Septal Deviation

WOS: 000327763000012The objective of this study was to evaluate the relationship between variations of the lateral wall of the nasal cavity and septal deviation (SD). Coronal and axial paranasal sinus CT images of 115 individuals (65 females, 50 males) were reviewed and the presence of pneumatisation and hypertrophy of the conchae was evaluated. Pneumatisation of the concha was classified as lamellar concha bullosa (LCB), bulbous concha bullosa (BCB), or extensive concha bullosa (ECB). If bulbous and extensive conchae and hypertrophic conchae were bilateral the side on which it was greatest was accepted as the dominant concha. The relationship between these variations and nasal septum deviation was also taken into account. Eighty-six (74.8%) of the 115 subjects had SD. Of these, 20 were not affected by the size of the middle nasal concha (MNC) or inferior nasal concha (INC). Thirty-four cases had dominant MNC, 20 had dominant INC, and 11 had both dominant MNC and dominant INC, and all of which had SD towards the opposite side. In one case there was SD towards the side in which the MNC was dominant. Our data indicate that coexistence of pneumatisation or hypertrophy of the conchae and SD was more common in adults compared to the results of similar studies conducted with a wide range of age groups, including children. Thus the presence of SD together with a large concha increases with age. A prospective study, which will include infants, will elucidate the relationship between conchae and SD

Anatomic Variations of Sphenoid Sinus Pneumatization in a Sample of Turkish Population: MRI Study

WOS: 000348581400003There are a number of variations regarding morphometric anatomy and degree of pneumatization of the sphenoid sinus. In our study, we planned to examine and show the differences of pneumatization of the sphenoid sinus particularly to guide the neurosurgeon during transsphenoidal surgery. Sagittal T1-weighed spin-echo Magnetic Resonance Images (MRIs) of 616 adult individuals (406 women and 210 men) were analyzed, retrospectively. According to the collected data from our study, the most common type of the sphenoid sinus was the sellar type (83%; n=511) for the whole study group. Of the 616 individuals 16.6% (n=102) had presellar type and 0.5% (n=3) had conchal type of sphenoid sinus. Preoperative detailed detection of the anatomical characteristics of sphenoid sinus is essential. A thorough information obtained from studies of the regional anatomy and awareness of its variability can provide a safe and accurate transsphenoidal and extended endoscopic skull base approaches

Mitomycin C, 5-fluorouracil, and cyclosporin A prevent epidural fibrosis in an experimental laminectomy model

This study examined the preventive effects of the local application of mitomycin C (MMC), 5-fluorouracil (5-FU), and cyclosporine A (CsA) in minimizing spinal epidural fibrosis in a rat laminectomy model. Thirty-two 2-year-old male Wistar albino rats, each weighing 400 ± 50 g, were divided into four equal groups: sham, MMC, 5-FU, and CsA. Each rat underwent laminectomy at the L5–L6 lumbar level. Cotton pads (4 × 4 mm2) soaked with MMC (0.5 mg/ml), 5-FU (5 ml/mg), or CsA (5 mg/ml) were placed on the exposed dura for 5 min. Thirty days after surgery, the rats were killed and the epidural fibrosis, fibroblast density, inflammatory cell density, and arachnoid fibrosis were quantified. The epidural and arachnoid fibroses were reduced significantly in the treatment groups compared to the sham group. Fibroblast cell density and inflammatory cell density were decreased significantly in the MMC and 5-FU groups, but were similar in the sham and CsA groups. The decreased rate of epidural fibrosis was promising. Further studies in humans are needed to determine the short- and long-term complications of the agents used here

Pre-Operative Measurement of the Morphometry and Angles of the Anterior Clinoid Process (ACP) for Aneurysm Surgery

The anterior clinoid process (ACP) is proximal to vital structures, such as the optic nerve, internal carotid artery and ophthalmic artery; therefore, study of its anatomy is important in guiding and defining surgery. We studied the anatomical structure of the ACP, including the angle formed by the apex of the ACP triangle, and its orientation, to provide information for easier and safer surgery. The measurement was performed on the axial planes of 242 cranial computerized tomography (CT) scans and 27 adult Turkish skulls of both sexes. The length of the ACP, width of the ACP at its base, the angle formed by the apical angle of the ACP triangle and the orientation of the ACP defined according to the sagittal midline were examined. In the Turkish skulls, the length and width of the ACP were similar to previous studies. Our study was the first to measure the angle and orientation of the ACP. The mean angle was 39.67 +/- 12.64 (16.6-89.5) and 135 posterior (55 %) and 107 medial (45 %) orientations. Surgical complications can be avoided by pre-operative radiological planning using axial CT scans and by determining whether the morphology is Type 2 (long, narrow, acute-angled), which requires total resection

The surgical treatment of far lateral lumbar disc herniation: 33 cases

 Surgical approaches to far lateral disc herniation are challenging because of the anatomical limitations in the region. We describe an extraforaminal approach for far lateral lumbar disc herniation (FLLDH) in a group of patients and discuss the results in patients with far lateral disc protrusion.Between 2006 and 2011, 33 patients (18 females, 15 males; mean age, 51.2 years) underwent surgery for FLLDH. The majority of patients had herniation at disc levels L3-4 (12 patients) or L4-5 (15 patients). All patients were operated on via either median-paramuscular (61%) or paramedian-intermuscular (39%) approaches. The mean VAS score improved from 7.3 preoperatively to 2.8 in the short-term. The long-term functional outcome of surgery according to the MacNab Criteria, the recovery was excellent, good, fair, and poor in 18, 11, 4, and 0 patients, respectively.The far-lateral approach for FLLDH is a safe, effective procedure that avoids the risk of secondary spinal instability

Aneurysmal bone cysts of the spine

WOS: 000315602300019PubMed ID: 23053752Aneurysmal bone cyst is a benign, relatively uncommon lesion, representing 1.4 % of primary bone tumors. The vertebral column is involved in 3-30 % of cases. This report describes clinical characteristics and treatment results of 18 patients with aneurysmal bone cyst of the spine. Between 1991 and 2008, 18 patients with aneurysmal bone cyst of the spine were surgically treated in our department. The clinical records, radiographs, histologic sections, and operative reports were analyzed. There were 11 male and 7 female patients; mean age was 22.1 years (range 7-46 years). Localizations were cervical (3), cervicothoracic (2), thoracic (3), lumbar (4), and sacrum (6). Tumor was localized on the left side in 11 cases, on the right side in 2 and at midline in 5 patients. The two most common clinical features were axial pain (14 patients) and radicular pain (8 patients). Neurological signs were paraparesis in 3, monoparesis in 6. Mean duration of symptoms was 9 months (range 3 months-3 years). All patients underwent surgery: total removal was performed in 13 patients and subtotal resection in 5. Posterior (11), anterolateral (1), or combined anterior-posterior (6) approaches were used. Mean follow-up duration was 112.3 months (range 4-21 years). We detected four recurrences in subtotal excision group (4/5), and one recurrence in total excision group (1/13). Treatment options for aneurysmal bone cysts are simple curettage with or without bone grafting, complete excision, embolization, radiation therapy, or a combination of these modalities. Radical surgical excision should be the goal of surgery to decrease the recurrence rate. Recurrence rate is significantly lower in case of total excision

Simvastatin reduces VEGF and NO levels in acute stages of experimental traumatic brain injury

This study was undertaken to evaluate the effect of simvastatin, a cholesterol-lowering agent, on vascular endothelial growth factors (VEGFs), nitric oxide (NO) levels and neuroprotection, in rats with experimentally induced traumatic brain injury (TBI). Forty Wistar albino rats were categorized into four groups: sham operated (S), trauma (T), trauma + vehicle (T + V) and trauma + simvastatin (T + S). The T, T + V and T + S groups were subjected to TBI. The T + V group was administered vehicle [ethanol:saline (1/2)] and the T + S group was administered 1 mg/kg of simvastatin 3 h after the injury insult. Blood and brain tissue specimens were obtained 24 h after the trauma to measure VEGFs and NO levels and perform histopathological examinations. The histopathological injury scores of brain tissues were significantly higher in the T group, and simvastatin significantly prevented brain injury in the T + S group. In the T group, significant increases of VEGF levels in serum and brain tissues were noted, which were prevented with simvastatin treatment in the T + S group. The markedly high levels of NO in brain tissues of the T group were decreased by simvastatin treatment in the T + S group. It can be concluded that, as evidenced by histopathological findings, simvastatin treatment improves neuropathology in acute stages of TBI

Comparison of clinical features and surgical outcome in focal cortical dysplasia type 1 and type 2
