Torticollis can be congenital or may be acquired in childhood. Acquired torticollis occurs because of another problem and usually presents in previously normal children. The causes of acquired torticollis include ligamentous, muscular, osseous, ocular, psychiatric, and neurologic disorders.

Different etiologies of acquired torticollis in childhood.

Vitamin K deficiency bleeding is one of the most common causes of acquired hemostatic disorder in early infancy. Although vitamin K is practiced routinely after every birth in Turkey, children with type of vitamin K deficiency bleedings (L-VKDB) can be encountered. We aimed to evaluate the clinical features of the children with L-VKDB reported from Turkey.

Childhood brain abscesses are a rare and potentially life-threatening condition requiring urgent diagnosis and treatment. This retrospective study analyzed the clinical and radiologic findings of 24 (7 girl, 17 boys) cases with brain abscess. Mean age was 92.98 ± 68.04 months. The most common presenting symptoms were nausea-vomiting (45.8%) and headache (41.7%). Brain abscess was most commonly located in the frontal region. Diffusion restriction was determined in 78.4% of lesions. The mean apparent diffusion coefficient value in these lesions was 0.511 ± 0.23 × 10(-3) mm(2)/s. Cultures were sterile in 40% of cases. Antimicrobial therapy was given to only 16.7% of cases. Predisposing factors were identified in 91.6% of cases (congenital heart disease in 20.8% and immunosuppression in 20.8%). Mortality level was 12.5%. In conclusion, immunocompromised states, and congenital heart disease have become an important predisposing factor for brain abscesses. Effective and prompt management should ensure better outcome in childhood.

The craniocervical junction is a complex anatomic location that contains the occipital bone, atlas, axis, and important complex ligamentous structures. The stability of this region is ensured only with the help of ligaments.

Tumors of the lateral and third ventricles are cradled on all sides by vital vascular and eloquent neural structures. Microsurgical resection, which always requires attentive planning, plays a critical role in the contemporary management of these lesions. This article provides an overview of the open microsurgical approaches to the region highlighting key clinical perspectives.

Total surgical resection of pituitary macroadenomas is difficult due to the location of the adenoma and the propensity to invade surrounding tissues. The purpose of this study was to evaluate the risk factors for invasive and aggressive pituitary macroadenomas using radiological, hormonal, clinical, and immunohistochemical markers.

Hypervascular intracranial tumors may cause serious bleeding in surgery. Though pre-operative endovascular embolization of tumor is a widely accepted method, sometimes despite embolization, an effective and safer intraoperative hemostatic technique is needed to prevent or at least decrease the massive bleeding from the tumors. The aim of this study was to investigate the effect of the ethyl alcohol (EA) injection in hypervascular tumors and find out whether it is likely to be an alternative method to prevent massive bleeding from tumor.

In the current literature, despite different surgical treatment protocols in different centers for spondylodiscitis due to lumbar surgery, there is no consensus on its surgical indications. In this study, we aimed to clarify the steps to be followed in the management and treatment of postoperative spondylodiscitis.

Barrel stave osteotomy is a widely used procedure in neurosurgery for the majority of craniosynostosis patients. Both in the intraoperative and postoperative periods, there is inevitable leakage type bleeding from the bones undergoing osteotomy. A number of studies have been performed in order to prevent this complication; however a concise procedure is still lacking.

AIM The surgical approaches for spinal tumors, to a great extent, have been developed in accordance with the developments in technology. Today, many surgical techniques are implemented as anterior, anterolateral, posterior, posterolateral and combined approach. Due to its low morbidity, posterior approach is more preferred one. Laminectomy is a widely used technique especially in neoplastic lesions. However, following laminectomy, there are complications like instability, kyphotic deformity and scar formation. In the current study, the excision of a tumor which was localized intradural-extramedullary at C3-C7 level with cervical hemi-laminoplasty technique is described. CASE A forty-seven year-old female patient was admitted to our clinic with increasing complaints of neck and left arm pain, left arm numbness and searing lasting for 10 years. In her examination, hypoesthesia in C4-7 dermatomes in left upper extremity, an increase in deep tendon reflexes and a bilateral Hoffmann positiveness were observed. METHOD With midline skin incision, C3-C7 laminas were opened unilaterally on the right side. Laminas were drilled with high-speed drill for wide-opening both on the midline obliquely and from the border of laminas-facet joint. After the tumor was totally excised, hemi-laminas were put into the previous position and reconstructed with mini-plates and screws. CONCLUSION Cervical hemi-laminoplasty provides a wide field of vision in the tumor surgery of this region. Besides, the reconstruction of hemi-laminas is important for stability. And, as the integrity of the spinal canal is preserved during reoperations implemented to this region, it will decrease the complication risk.

Television tip overs and head traumas in children showed an increase in the recent years in Turkey and throughout the World. In this study, the injury types, the surgical interventions and the children exposed to head trauma due to an accident caused by a falling television were investigated retrospectively. Some cautions were suggested in order to prevent these injuries.
