Evaluation of latex allergy in patients with meningomyelocele.

Seventy-six patients with meningomyelocele were evaluated for latex sensitivity by medical history and epicutaneous skin testing. Four different latex glove extracts, two nonlatex glove extracts, cornstarch, selected inhalant antigens, and negative and positive controls were used for skin testing. Forty-nine patients (64.5%) were skin test positive to latex extracts (latex-positive group). Twenty-four patients (49%) of the latex-positive group and none of the latex-negative group had histories of immediate reactions to latex products (P less than .001). The latex-positive group had a higher mean number of surgical procedures, 12.67 +/- 11.27, compared with 6.89 +/- 6.55 (P less than .001) in the latex-negative group. Twenty-three of the latex-positive patients (47%) used latex products daily compared to seven patients (26%) in the latex-negative group (P = .073). Twenty latex-positive patients (41%) had atopy compared with five patients (19%) of the latex negative group (P = .041). There was no significant difference between the two groups in age, sex, daily catheterization, or positive skin tests to cornstarch. All 76 patients tested negative to the nonlatex glove extracts. Ten control subjects tested negative for all latex and nonlatex glove extracts.

The insular cortex and the pathophysiology of stroke-induced cardiac changes.

Over the past fifty years considerable clinical evidence has accrued to demonstrate involvement of the cerebral cortex in cardiac function. Hemispheric stroke is often associated with electrocardiographic (ECG) evidence of cardiac repolarisation abnormalities. In addition strokes of all types are associated with specific pathological changes in the ventricular myocardium (myocytolysis). These effects are not attributable to concomitant cardiac ischemic disease in the majority of cases. The insular cortex has recently been shown to contain a site of cardiac representation. Prolonged stimulation of this region in the rat produces ECG and cardiac pathological changes similar to those observed after human stroke. It is suggested that middle cerebral artery stroke in certain cases either directly or indirectly leads to insular disinhibition, and increased autonomic activity represented by cardiac changes which significantly influence prognosis.

Screening for early dementia using memory complaints from patients and relatives.

This study examined whether the subjective impression of memory function might differentiate healthy elderly subjects from patients with memory complaints, and whether memory complaints differed between patients with and without a dementing illness. Both self-assessment and relatives' responses on a new memory questionnaire differentiated patient groups from control subjects. The relatives' form measuring deterioration in memory function over time identified dementing individuals from those with non-dementing causes for their memory complaints. Factor analysis indicated that patients' memory complaints correlated with depression rather than objective memory performance, while relatives' ratings correlated with objective memory scores, not depression. Stepwise discriminant function analyses showed that objective memory testing greatly improved specificity but not sensitivity of the subjective memory questionnaire alone.

Periapical actinomycosis. An unusual case report.

An unusual case of actinomycosis in the oral cavity is reported. The strict anaerobic qualities of Actinomyces israelii make laboratory culturing and growing of this organism difficult. Accordingly, the diagnosis was based on the histopathologic report. Because of the atypical clinical presentation, i.e., lack of any discharging sinus tract on the skin surface, and the histopathologic reports, it was postulated that the actinomycosis was superimposed on an existing granulomatous tissue.

Renal calculi and biochemical abnormalities. In children with myelomeningocele and heoconduit diversion.

Of 38 pediatric cases of ileoconduit urinary diversion of myelomeningocele, 4 with renal calculi are presented. An increased risk of renal calculus formation may be imposed on children with myelomeningocele with ileoconduit urinary diversion especially so in functionally and anatomically abnormal kidneys and in chronic renal infection with urea-splitting bacteria. It is not clear why the ileoconduit procedure should increase the incidence of renal calculi in such children.
