Morbidity, mortality, and recurrence rates of hydatidosis uncovered by the cooperative study and the literature survey were not statistically significant.
In this study we aimed to evaluate the role of closed-suction drainage on the extent of epidural fibrosis (EF) after lumbar disc surgery and to define a new grading system of epidural fibrosis in these patients, based on magnetic resonance imaging. Seventy-nine patients (34 women, 45 men) with a unilateral, single-level lumbar disc herniation were included in this study. Forty-one patients in whom closed-suction drainage was implanted were compared with 38 patients in whom the drain was not implanted. We have used a new grading system for the extent of epidural fibrosis, on the basis of follow-up magnetic resonance imaging findings. Pain intensity was evaluated by visual analog scale (VAS), and the patients' function and working ability were measured according to the Prolo functional-economic scale. We conclude that, in patients operated on for unilateral, single-level lumbar disc hernias, implantation of closed-suction drainage into the operation site results in less formation of EF radiologically and yields better clinical outcome.
Intracranial hydatid cysts, which are common in certain areas worldwide, almost always develop at an intraparenchymal site. However, the literature on intraventricular hydatid cysts consists of only 6 independent case reports and about 30 cases that are described in large series. We report on a 10-year-old girl who was admitted with an intracranial cyst. She complained of headache of 10 months' duration that had intensified significantly over the 3 weeks immediately before her admission. The results of a neurologic examination showed bilateral papilledema and slight left hemiparesis. Magnetic resonance imaging revealed a right temporo-parieto-occipital cystic lesion that was causing the shifting of the midline structures to the contralateral side. The giant cyst was successfully removed without rupture. The possibility of infection with Echinococcus granulosus should be included in the differential diagnosis of unspecific neurologic symptoms such as a progressively worsening headache, especially in pediatric patients from the geographic areas in which that parasite is endemic.
Conservative treatment of an epidural hematoma is not always effective in children. We describe an 8-year-old boy who had been followed up conservatively for 10 days at a local hospital due to acute epidural hematoma. A new CT revealed an expansion of the former hematoma accompanied by a thick hyperdense layer. Because the patient presented with symptoms of elevated intracranial pressure, an immediate craniotomy was performed to evacuate the hematoma. The ossified layer, which was densely adhered to the dura mater, was also completely removed. Rapid ossification and/or calcification of an epidural hematoma appearing 10 days after a head injury have not been reported previously. Possible mechanisms of rapid ossification are also discussed in relation to the present report, and the relevant literature is reviewed.
If the patients experience severe or mild back pain with higher preoperative KA, especially in the first 2 months, then they deserve detailed radiologic examination. To avoid subsequent fracture in the same or adjacent level, vertebral body should be filled adequately and sagittal balance should be obtained with KA correction. BK alone did not influence the incidence of subsequent VCF.
Our data suggest that RFT destruction of ganglion impar in patients with chronic coccydynia has an effective outcome and patients responding to RFT have significantly lower post-RFT pain scores. The most important factors determining success of this procedure is strict patient selection criteria and the technique of the procedure.
The authors report four patients with intracranial hydatic cysts. One patient had a pontine lesion which was punctured and aspirated and the cyst wall removed with a satisfactory outcome. The second patient had multiple cysts which was comparable to meningeomatosis. She had a rapidly deteriorating neurologic condition which proved to be fatal in spite of two consecutive surgical interventions. The third patient had nine lesions although only six were evident on the MRI. All of the cysts were removed, while two cysts ruptured. Multiple paracardial cysts of this patient were surgically removed shortly after the craniotomy. The last patient, again with multiple intracranial hydatid cysts had safe, total removal of all cysts. The first postoperative control CT raised the possibility of recurrence since the CT was highly suggestive of a hydatid cyst. However, this was not confirmed in the follow-up CT examination. Problems and the solutions of management are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
