Association of plasma levels of human immunodeficiency virus type 1 RNA and oropharyngeal Candida colonization.

The pathophysiology of oropharyngeal candidiasis in patients infected with human immunodeficiency virus (HIV) type 1 is poorly understood. Association between oropharyngeal yeast carriage and various clinical factors in HIV-1-infected patients was studied in 83 patients with no clinical evidence of thrush and no recent antifungal use. Of the clinical factors measured, the only correlate of yeast colonization was with plasma HIV-1 RNA levels (P=.001), whereas the correlation with CD4 cell count was poor (P=.36). By multivariable regression modeling, plasma HIV-1 RNA was the only parameter that correlated with the extent of colonization with Candida infection (P=.003). These data indicate that the presence and amount of asymptomatic oropharyngeal yeast carriage in persons with HIV-1 infection is more significantly correlated with plasma HIV-1 RNA levels than with CD4 cell count. Further studies on the effect of HIV-1 on oropharyngeal yeast colonization, infection, and local immunity are warranted.

Chronic spinal subdural hematoma.

A 55-year-old woman with chronic spinal subdural hematoma, diagnosed by magnetic resonance (MR) is presented. There was no coagulation defect, anticoagulant therapy, or trauma.

Encapsulated spinal epidural hematoma in an octogenarian.

An 88-year-old man was found at laminectomy to have an encapsulated spinal epidural hematoma. The surgical result was gratifying and reinforced a recent statement that spinal surgical procedures in the very elderly should not be withheld on the basis of age alone. Moreover, the rarity of this pathology in this age group and the clear identification of the lesion on the computed tomography scan of this case are to be noted.

Vasospasm after acoustic neuroma removal.

A case of a acoustic neuroma with a two-stage removal due to severe bleeding is presented. The patient remained drowsy after the second operation and by the 8th day deteriorated quickly with progressive right hemiplegia and aphasia. The cerebrospinal fluid was bloody, vasospasm was shown in the angiograms, and an ischemic area was disclosed in the computed tomography scan. The outcome and the neuroradiologic examinations suggested that blood in the basal cisterns caused the vasospasm and the brain ischemia. A review of the literature disclosed only one similar case.

[Incidental syringohydromyelography: report of a case].

The radiological findings of syringomyelography are described in a five years old patient who underwent a percutaneous injection of opaque contrast medium (Lipiodol) into the intraspinal syringomyelic cavity. The clinical picture, the usual diagnostic methods and the place of syringomyelography for the diagnosis of syringomielia are discussed.

[Computed tomography in the follow-up of patients with intracranial tumors].

Computed Tomography (CT) has been very useful in the follow-up of patients with brain tumors. Soon after the craniotomy, CT would show any residual tumor if an incomplete excision was done. CT has been essential when one needs to evaluate any deterioration in the patient's neurological status post operatively. In such instances, CT may detect brain edema, hematoma, hydrocephalus and the presence of air. CT findings are more accurate than those obtained from conventional neuroradiology or from intracranial pressure monitoring, being also more innocuous than those methods. Later in the post operative follow-up, CT allows, besides precocious diagnosis of tumor recurrences, a good evaluation of the results obtained by chemiotherapy or radiotherapy. When hydrocephalus is accompanying the primary pathology, ventricular size can be rapidly evaluated by CT. Difficulties may arise when one wishes to differentiate CT images of radionecrosis from tumor recurrences at least in the initial stages.

[Neuroenteric cyst: report of a case].

The case of 15 years old boy with an enterogenous cyst causing compression of the spinal cord at T-2 is reported. The diagnosis was made by thoracic laminectomy and confirmed by histological examination. The motor disorders improved progressively after surgery.

[Computerized tomography in ventral and lateral prone position in the differential diagnosis of subdural hematoma and cortical atrophy].

The differential diagnosis between brain atrophy versus subdural effusion in children has shown some difficulties in a few cases, mainly when the frontal subarachnoid space is very large on computed tomography. We think that a simple procedure, that is, CT scans in the lateral and prone position following the standard examination, may be worth to clarify those cases of doubtful diagnosis.

[Tumoral form of cerebral cysticercosis: diagnosis by computerized tomography].

Solitary granulomatous lesions due to cysticercosis in the brain were found by computed tomography in six patients. The CT images were in all cases very similar to those from brain neoplasms. The cerebrospinal fluid complement fixation test for cysticercosis was negative in all of the cases. The definite etiological diagnosis could only be made by craniotomy in this series.

[Use of the inflated balloon catheter in the treatment of carotid-cavernous fistula].

In the vast majority of techniques used to treat carotid-cavernous fistulas the carotid artery has been occluded. Occlusion of the fistula with preservation of carotid blood flow is achieved by new techniques as those proposed by Parkinson, Serbinenko and Mullan. However the sophisticated equipments and surgical acts which are needed for these methods has not allowed its general use. The use of Fogarty type balloon catheters has had a place in the treatment of carotido-cavernous fistulas. The carotid artery has to be occluded too, but the procedure is much safer and easier. Our results in a series of 6 cases are reported. Considerations about indications and the technical aspects are made. The results were good and the procedure may be used with conventional equipment.
