RESUMEN
Total scalp avulsion injury with cervical spine injury is rare. This article is to describe the technical difficulties and precautions to be taken during anatomical replantation. The patients with cervical spine injury should not be considered as an absolute contraindication for anatomical replant if patients are fit for general anaesthesia. We found that the supratrochlear and supraorbital vessels which are anterior and superficial temporal vessels which are lateral can be used to replant without much technical difficulty. We conclude that anatomical replant is always better keeping in mind the technical limitations of anatomical replant in case of cervical spine injury.
RESUMEN
Profound hearing loss requiring cochlear implantation and arachnoid cyst requiring placement of Cysto-Peritoneal Shunt (CPS) are two commonly seen entities. However, there are very few published cases of patients requiring both of them. The present report describes the importance of multidisciplinary surgical planning in one such patient.
RESUMEN
BACKGROUND AIMS: Spinal cord injury (SCI) is a medically untreatable condition for which stem cells have created hope in the last few years. Earlier pre-clinical reports have shown that transplantation of bone marrow (BM) mesenchymal stromal cells (MSC) in SCI-simulated models can produce encouraging results. In a clinical pilot study, we investigated the growth kinetics of BM MSC from SCI patients, their safety and functional improvement post-transplantation. METHODS: Thirty patients with clinically complete SCI at cervical or thoracic levels were recruited and divided into two groups based on the duration of injury. Patients with <6 months of post-SCI were recruited into group 1 and patients with >6 months of post-SCI were included into group 2. Autologous BM was harvested from the iliac crest of SCI patients under local anesthesia and BM MSC were isolated and expanded ex vivo. BM MSC were tested for quality control, characterized for cell surface markers and transplanted back to the patient via lumbar puncture at a dose of 1 x 10(6) cells/kg body weight. RESULTS: At the time of writing, three patients had completed 3 years of follow-up post-BM MSC administration, 10 patients 2 years follow-up and 10 patients 1 year follow-up. Five patients have been lost to follow-up. None of the patients have reported any adverse events associated with BM MSC transplantation. CONCLUSIONS: The results indicate that our protocol is safe with no serious adverse events following transplantation in SCI patients. The number of patients recruited and the uncontrolled nature of the trial do not permit demonstration of the effectiveness of the treatment involved. However, the results encourage further trials with higher doses and different routes of administration in order to demonstrate the recovery/efficacy if any, in SCI patients.

INTRODUCTION: Trigeminal Neuralgia (TGN) is a syndrome characterized by Paroxysmal, shock like hemifacial pain. Among the various treatment options micro vascular decompression (MVD) has gained popularity in the recent years. MATERIALS AND METHODS: 182 patients underwent MVD, between 1995-2007 out of 530 patients treated for Trigeminal Neuralgia at our service. All were operated by retro auricular sub occipital craniectomy by a single surgeon using autologous muscle graft. They were assessed for pain relief, complications and the data was analysed. RESULTS: Males were 84 (61.3%) females 53 (38%) with a ratio of 1.5=1. Age ranged from 25-75 years. Duration of symptoms ranging from 6 months to 25 years (average 4-6 years). Seventy seven (56.2% were affected on the right side whereas 60 (43.8%) had pain on the left side. Imaging demonstrated vascular compression in 84 (61%). At surgery superior cerebellar artery was the commonest cause of compression in 71.5%. More than one artery was found in relation to the nerve in 15.3%. There was no mortality, CSF leak 2.9% and transient facial palsy in 2.2% were the notable complications. CONCLUSION: MVD is the procedure of choice for TGN if there is no contraindication for surgery. Adequate tissue respect, meticulous surgical steps and experience will reduce complications. Autologus muscle graft can give comparable and durable results possibly with lesser complications.
RESUMEN
More than one third of patients with subarachnoid hemorrhage (SAH) develop clinically significant vasospasm, as a leading morbidity and mortality factor for these patients. It is widely accepted that a) Degradation products of blood are the causative factors of vasospasm b) The amount of subarachnoid blood seen on admission CT is correlated to the risk of vasospasm c) Reducing the subarachnoid clot burden at the time of surgery reduces the risk of vasospasm. But there is no existing method to clear the blood from subarachnoid spaces satisfactorily. We have evaluated safety and feasibility of fluid exchange catheter system in SAH, to achieve this goal. We were successful in clearing cisternal blood in three patients with aneurysmal rupture with fluid exchange catheter system. Baseline CT scan of brain was performed immediately after the surgery and then at the end of irrigation. The amount of subarachnoid blood was evaluated. This innovative, fluid exchange catheter system infuses and aspirates micro volumes of drug solution in a cyclic mode, ensuring isobaric exchange of fluids. The result is good clearance of blood in subarachnoid spaces were seen in all the patients. Also, significant improvement in neurological deficits secondary to vasospasm was seen. We conclude that the fluid exchange catheter system is safe and adoptable in neurosurgical practice.
RESUMEN
Parkinson's disease (PD) is a progressive neurodegenerative disease for which stem cell research has created hope in the last few years. Seven PD patients aged 22 to 62 years with a mean duration of disease 14.7+/-7.56 years were enrolled to participate in the prospective, uncontrolled, pilot study of single-dose, unilateral transplantation of autologous bone-marrow-derived mesenchymal stem cells (BM-MSCs). The BM-MSCs were transplanted into the sublateral ventricular zone by stereotaxic surgery. Patients were followed up for a period that ranged from 10 to 36 months. The mean baseline "off" score was 65+/-22.06, and the mean baseline "on" score was 50.6+/-15.85. Three of 7 patients have shown a steady improvement in their "off"/"on" Unified Parkinson's Disease Rating Scale (UPDRS). The mean "off" score at their last follow-up was 43.3 with an improvement of 22.9% from the baseline. The mean "on" score at their last follow-up was 31.7, with an improvement of 38%. Hoehn and Yahr (H&Y) and Schwab and England (S&E) scores showed similar improvements from 2.7 and 2.5 in H&Y and 14% improvement in S&E scores, respectively. A subjective improvement was found in symptoms like facial expression, gait, and freezing episodes; 2 patients have significantly reduced the dosages of PD medicine. These results indicate that our protocol seems to be safe, and no serious adverse events occurred after stem-cell transplantation in PD patients. The number of patients recruited and the uncontrolled nature of the trial did not permit demonstration of effectiveness of the treatment involved. However, the results encourage future trials with more patients to demonstrate efficacy.
