Preadmission testing in elective surgery--improving the process.

Patients admitted for elective surgery (inguinal hernia, varicose veins and hemorrhoids) were evaluated in order to determine the differential impact between two methods of performing preadmission testing (PAT) on the length of stay and on the completeness of the requested data. The two methods compared were: conventional, whereby patients performed the PAT in the regular clinics and laboratories of a health care organization (health maintenance organization-like) and an automated multiphasic health testing system (AMHTS). For these particular operations no significant difference in length of stay between the two methods was found. Based on the accumulated experience with these modalities, a model for performing preadmission procedures (in a preanesthetic clinic for elective surgery) was designed in order to identify high-risk patients. Use of this model can reduce cost, increase patient satisfaction and prevent hospitalization when immediate surgery is contra-indicated.

Juxta-centromeric fragility of chromosomes 1, 2, 9, 16, and immunodeficiency. Special reference to the fragility of chromosome 2 and its oncogenic potential.

Juxta-centromeric fragility of chromosomes 1, 2, 9, 16, has been described at least thrice in unrelated patients in association with combined immunodeficiency. This association has been confirmed by our findings in both immunodeficient and cancer patients. In our opinion, both the fragility and the immunodeficiency are the results of persistent viral infections by certain DNA (i.e.: Herpes-, Papova-) viruses or RNA (retro-) viruses (i.e. HTLV), which are lymphotropic. The immunodeficiency may be due to virus-cell, cell to cell, or virus-virus interactions. According to our findings, centromeric fragility of chromosome 2 appears to have a particular oncogenic potential probably because of its location in proximity to immunoglobulins genes. We suggest that centromeric fragility of chromosomes 1, 2, 9, 16, may be one of the symptoms of an incipient Acquired Immunodeficiency Syndrome (AIDS) which will not necessarily develop fully.
