Context: Internal rigid fixation provides immediate stability of the occipito-cervical (OC) junction for treatment of instability; however, in current practice, the optimal OC junction stabilization method is debatable. Aims: The aim of this study to test the safety and efficacy of a newly designed modified inside-outside occipito-cervical (MIOOC) plate system for the treatment of instability. Settings and Design: This was a feasibility study of MIOCC plate system. Subjects and Methods: Five male and four female patients with OC instability were treated using MIOOC plate system. Stabilization rate, safety, and efficacy were evaluated radiologically and clinically. Results: Mean age of the patients was 35 ± 11 (range: 22–58) years. Etiology of OC instability included trauma, neoplasm, congenital abnormalities, and iatrogenic. The fusion levels ranged from occiput-C3 to occiput-C6. Mean follow-up duration was 22 ± 10 (range: 6–46) months. There were neither complication nor was there any need for plate revision or screw pullout. Mortality occurred in one patient due to primary malignancy at 6 months; otherwise, no morbidity was observed. During the follow-up, no recurrent subluxation or newly developed instability at adjacent levels occurred. All patients showed a satisfactory union at the most recent follow-up examination. Conclusions: These preliminary results suggest that the MIOCC plate system is a useful and safe method for providing immediate internal stability of the OC junction. Using a multi-piece plate design in this plate system provided easy implantation and a better interface between plate and OC bones. Further, clinical studies and long-term results are needed to determine the reliability of the MIOOC plate system. [ABSTRACT FROM AUTHOR]

Objectives: The roles of gabapentin and pregabalin are well established in the management of chronic neuropathic pain. Here, we investigated the effectiveness of pregabalin and gabapentin for treating acute neuropathic pain following lumbar discectomy. Methods: This prospective, non-randomized, and observational study included 54 patients who experienced acute neuropathic pain after lumbar discectomy. The assessments included the Leeds assessment of neuropathic symptoms and signs scale (LANSS), the Oswestry disability index (ODI), and the visual analog scale (VAS) pre-operatively and at 3 days, 6 months, and 1 year after surgery. The LANSS scores ≥12 suggest the presence of neuropathic pain. Those patients who reported neuropathic pain were randomly treated with gabapentin or pregabalin. Results: In the gabapentin group, the LANSS scores increased to 14 at 3 days after surgery. The patients improved neurologically and on the LANSS, which decreased to 10 points 6 months after surgery and to 4 points at 1 year (P < 0.001). In the pregabalin group, the LANSS scores increased from 12 to 16 points on post-operative day 3 and then decreased to 12 and 5 at the 6-month and 1-year follow-ups, respectively (both P < 0.001). The ODI and VAS scores significantly improved in both groups (P < 0.001). Discussion: Many patients may suffer from neuropathic pain in the early post-surgical period after lumbar discectomy. Gabapentin and pregabalin are anticonvulsant agents that may decrease perioperative central sensitization and early post-surgical neuropathic pain. Gabapentin and pregabalin effectively relieved neuropathic pain and prevented the conversion of acute pain to chronic pain at the 1-year followup after lumbar discectomy. [ABSTRACT FROM AUTHOR]

Background and Study Aim To enhance the visualization of the intracranial vasculature of cadavers under gross examination with a combination of imaging modalities. Material and Methods A total of 20 cadaver heads were used to test two different perfusion techniques. First, fixed cadaver heads were perfused with water; second, fresh cadavers were perfused with saline and 10% formalin. Subsequently, brains were removed and fixed. The compounds used were silicone rubber, silicone rubber mixed with powdered barium sulfate, and silicone rubber mixed with tantalum dioxide prepared by the first perfusion technique and gelatin mixed with liquid barium prepared with the second technique. Conventional X-ray imaging, computed tomography (CT), dynamic computed tomography (dCT), and postprocessing three-dimensional (3D) images were used to evaluate all the heads. Results Gelatinized barium was better visualized when compared with tantalum dioxide in conventional X-ray images. The blood vessels injected with either tantalum dioxide or gelatinized barium demonstrated a higher enhancement than the surrounding soft tissues with CT or dCT. The quality of the 3D reconstruction of the intracranial vasculature was significantly better in the CT images obtained from the gelatinized barium group. Conclusions Radiologic examinations of the heads injected with gelatinized barium facilitates the 3D understanding of cerebrovascular anatomy as an important tool for neuroanatomy training.

Choroid plexus carcinoma is a malignant intraventricular tumor of childhood with poor prognosis. Complete surgical resection is the most important prognostic factor. Unfortunately, complete resection of the CPC is a challenge for neurosurgeons due to extreme vascularity of the tumor, its large size, and its tendency to make invasion to the adjacent brain parenchyma. Here we present a 24-month-old boy with a triventricular CPC, to whom multi-staged endoscope-assisted microsurgical technique was performed. Complete resection was achieved. Postoperatively patient was improved neurologically and discharged home in stable condition. It is shown that multi-staged endoscope-assisted microsurgical technique definitely help neurosurgeons in dealing with this challenging tumors. [ABSTRACT FROM AUTHOR]

Alkaptonuria is a rare autosomal recessive disorder which causes degenerative changes in cartilage, intervertebral disc and other tissues. Although intervertebral disc degeneration is common in alkaptonuria; where there are only a few patients treated surgically for lumbar disc disease. Diagnosis of aIkaptonuria after black colored lumbar discectomy material is a rare condition. We present a case of alkaptonuria, in which the patient was diagnosed after lumbar discectomy.

Abdominal wall haematomas are uncommon and often misdiagnosed entities. Most of the time the haematoma is produced by rupture of the epigastric vessels, deep circumflex iliac artery or tear in the rectus or lateral oblique muscle. Predisposing factors such as arteriosclerosis of vessels, old age, straining while urinating and coughing and use of anticoagulant agents make bleeding more likely. Here, two uncommon cases who experienced cardioembolic stroke are described. The patients were given enoxaparin sodium urgently, administered to the stomach area subcutaneously. They presented with abdominal masses, periumbilical and inguinal ecchymosis. Their haemoglobin levels dropped. Abdominal CT scan and ultrasonography revealed rectus sheath and internal abdominal oblique muscle haematomas. The patients were treated conservatively. This report concerns this rare condition, often misdiagnosed in unconscious patients, that has not been reported as being due to cardiogenic brain embolism in the literature to date.
