Local complications following intravenous benzodiazepines in the dorsum of the hand. A comparison between midazolam and Diazemuls in sedation for dentistry.

Two hundred patients requiring sedation for minor oral surgery were randomly allocated to receive either midazolam or diazepam as Diazemuls intravenously through a 23-gauge indwelling needle in the dorsum of the hand. The site of injection was inspected at 7 days and 14 days post injection and assessed for pain, tenderness, redness, induration, painless thrombosis, and thrombophlebitis. The mean dose administered was 0.119 mg/kg of midazolam and 0.298 mg/kg of Diazemuls. At 7 days there was no significant difference in venous complications. At the 14 day follow up, the midazolam group had a significantly greater incidence of tenderness and redness (p less than 0.001 and p less than 0.05 respectively using Chi squared test). The incidence of thrombophlebitis in the midazolam group was 2% at 7 days and 1% at 14 days, the corresponding figures in those given Diazemuls being none and 1% respectively. We conclude that the dorsum of the hand is a satisfactory site of injection for administration of these drugs. The higher incidence of minor complications at 14 days following midazolam was offset by its more reliable amnesic properties.

Comparative computer graphics and solution studies of the DNA interaction of substituted anthraquinones based on doxorubicin and mitoxantrone.

1-[[(Diethylamino)ethyl]amino]- and 1,4-, 1,5-, and 1,8-bis[[(diethylamino)ethyl]amino]anthraquinones are shown to intercalate into DNA. Computer graphics modelling of their intercalation into the self-complementary deoxydinucleoside d(CpG) showed differences in binding properties. While the 1-substituted compound can bind from either groove, the 1,8-disubstituted compound binds with both substituents in the major groove. In the low-energy state of the complex with the 1,5-disubstituted compound, this ligand "straddles" the site with a substituent in each groove--to do this, the compound must bind to a non-base-paired region, so inducing base pairing. The 1,4-compound binds from the major groove; "straddling" is also possible if full minimization of deoxydinucleoside geometry is performed. The differences in binding mode and interaction energies are reflected in the affinities of interaction (1,5- greater than 1,4- much greater than 1,8- greater than 1-); also the antiproliferative effects in vitro are in general agreement with this ranking.

Topical carbenoxolone sodium in the management of herpes simplex infection.

Topical carbenoxolone was discovered by chance to be a highly effective anti-viral agent and was subsequently used in the management of Herpetic gingivostomatitis and recurrent Herpes labialis. A marked reduction in the healing time and pain associated with these lesions was noted. A discussion of the possible mechanisms of action of carbenoxolone is included.

The prevalence of Sarcocystis spp in dogs and red foxes.

Protozoan parasites of the genus Sarcocystis have been recognised for many years as intramuscular cysts of numerous vertebrates. It is only comparatively recently that the two-host nature of the life cycle has been recognised and that the intramuscular cysts are a stage in the developmental cycle of coccidian parasites of flesh eating mammals (Fayer 1974, Fayer and Johnson 1973, 1974, Rommel and others 1972, Dubey 1976). Carnivores ingest the intramuscular cysts from herbivores and presumably from other animals too and eventually shed sporulated tetrazoic sporocysts in their faeces. The cystic stages which occur in the flesh of herbivores are probably non-pathogenic but the earlier stages in which schizonts develop in vascular endothelium may be severely pathogenic. Sarcocystis cruzi, S ovicanis and S porcifelis are known to be severely pathogenic in cattle, sheep and pigs respectively (Dubey 1976). Observations on the prevalence of Sarcocystis spp in the faeces of working farm dogs, greyhounds and foxes (Vulpes vulpes) are recorded.

The cost of acute asthma--how much is preventable?

Asthma is known to be widely under-treated, and unnecessary morbidity from the disease is common. This paper reports a prospective survey of hospital admissions for acute asthma and assesses the efficacy of pre-admission therapy in terms of preventing hospital admission. District and national costs were estimated for hospital admission of patients with acute asthma and, although the direct cost to the patients was not measured, a calculation was made of the number of working days lost annually. The results of this survey show the need for improved education of both doctors and patients, and in particular for improved clinical management. The findings also suggest that the cost to the patient, including those costs incurred by hospital admission, are potentially preventable.
