Nitroethane poisoning from an artificial fingernail remover.

Confusion between acetone fingernail polish removers and artificial fingernail products containing acetonitrile and N,N-dimethyl-p-toluidine has resulted in pediatric morbidity and mortality. In the present case, a 20-month-old boy drank less than one ounce of Remove Artificial Nail Remover containing 100% nitroethane. In the emergency department he displayed cyanosis and 39% methemoglobinemia.

Reference values for red cell survival times.

The first purpose of this investigation was to investigate in 35 young normal male subjects the use of the Dornhorst function and the weighted-mean method to calculate reference values for mean red cell survival time with and without correction for elution of 51Cr. We compared survival times calculated with the Dornhorst and weighted-mean methods with survival time estimated with linear or exponential models. Two methods to correct for elution of 51Cr from red cells were investigated.

A computer program in compiled BASIC for the IBM personal computer to calculate the mean platelet survival time with the multiple-hit and weighted mean methods.

We developed an easy-to-operate computer program for the IBM personal computer to calculate, display and store in a database platelet kinetic data determined by analysis of the rate of clearance of radiolabeled blood platelets from the circulation. This was done by curve fitting using the weighted mean method and multiple-hit model. These models are complementary and calculating the mean platelet survival time with both is recommended.

Chronic sclerosing osteomyelitis: treatment considerations in an atypical case.

Chronic sclerosing osteomyelitis has been frequently described in the literature but little has been recommended for the management of the resistant cases that fail to respond to conservative treatment. This report describes the long term management of a particularly aggressive case of CSO and indicates maxillary sinus disease as a possible etiologic factor in CSO of the maxillary alveolus. Treatment required in more extensive cases must be as aggressive as dictated by the entire disease process and the total medical evaluation.

A prototype articulator for planning orthognathic and craniofacial surgery.

Current techniques and hinge-type articulators do not provide sufficient information and versatility for the planning of orthognathic and craniofacial surgery. Dental articulators either require plaster of paris for mounting or they do not accommodate movement of both casts in all directions of space. A prototype articulator that satisfies movement of both casts in all directions of space is successfully being used as an adjunct in planning orthognathic and craniofacial surgery.
