Prophylactic use of large doses of TA provides an effective, safe, and cheap method for reducing blood loss during and after spinal operations. Hence, TAmay help in reducing not only transfusion related complications but also operative expenses. Considering the limited number of patients in this study, our results need, however, to be validated on a larger number of patients, probably in a multicenter study.
This paper is an attempt at defining the most efficacious surgical and antifungal therapy for invasive cranial and intracranial aspergillosis, and is based on experience with nine non-immunocompromised patients treated and followed-up by the authors between 1983 and 1994; as well as on the summary of previously reported cases and advances in therapy of this condition. Depending on the degree of aspergillar involvement of the cranial base and intracranial structures, a classification, with implications for treatment and prognosis, is also proposed. Two patients had extracranial skull base erosion; whereas relentlessly progressive granulomas, mimicking malignancy, invaded the skull base and intracranial contents in seven cases. Of these seven patients with cranial and intracranial invasion, two died of acute intracranial haemorrhage due to fungal invasion of cerebral blood vessels. In two patients, complete surgical eradication of the disease proved impossible due to cavernous sinus involvement, while residual aspergillomas are still present in orbit and paranasal sinuses (PNS) in a further two patients in spite of multiple surgical procedures and prolonged antifungal chemotherapy (AFC). What appears to be a cure has been effected in one patient only. Multiple therapeutic strategies were used. Biopsy plus systemic AFC was ineffective, surgical drainage and debridement plus systemic AFC resulted in long-term survivals but no cure. Radical surgery in conjunction with systemic and local (intracavitary) AFC should be considered to improve an otherwise poor prognosis.
This study is an attempt to establish that CSF shunt infection has a role in the aetiology of multiloculated hydrocephalus. The authors carried out a review of 12 cases of multiloculated hydrocephalus who were treated at King Khalid University Hospital between 1988-1994. The multiloculation appears to have developed following the shunt infection in all cases. The hydrocephalus was related to an intraventricular haemorrhage (IVH) in 9 patients and was congenital in 2 patients and post-meningitic in 1 patient. The shunt infection was caused by a gram-negative organism in 8 patients and duration of external ventricular drainage ranged from 9-24 (median 13) days. The diagnosis of multiloculated hydrocephalus was made on average 2 months after the shunt infection. In three patients endoscopic fenestration of intraventricular septations was attempted but was effective in only one case. The other patients were managed by two shunts (9 patients) and three shunts (2 patients). At a mean follow-up of 15 months, the shunt revision rate of the patients was 0.4/year. One patient died of multiple brain abscesses and 6 patients remain severely disabled. The poor outcome may also be related to the original IVH as well as the multiloculated hydrocephalus. The study also shows that patients with post-haemorrhagic hydrocephalus, who develop a shunt infection due to gram-negative organisms and in whom the CSF fails to be cleared of the infection following 12 days of external drainage appear to be at risk of developing multiloculated hydrocephalus.
In this study of 43 children who had surgery for traumatic extradural hematoma (EDH) at Frenchay Hospital, England, between 1975 and 1987, the authors attempt to outline the various clinical characteristics of EDH which are different in children (age range 1-15 years) and adults (age range 16-84 years). The results confirm that children with traumatic EDH are less likely to have injury be caused by an RTA, are less likely to remain unconscious from the time of injury to the time of the operation, and are less likely to require immediate surgery (less than 6 hours after injury). In addition, the CT scan is less likely to show in associated intradural injury, and the outcome is significantly better.
An unusual case of bilateral femoral nerve compression caused by iliacus hematomas in a patient on anticoagulant therapy is herein reported with special reference to the comparative diagnostic value of ultrasonography, computerized tomorgraphy, and magnetic resonance imaging. The importance of early surgical decompression is also emphasized.
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.
