Cauda equina syndrome after spinal tetracaine: Electromyographic evaluation-20 years follow-up

CAUDA equina syndrome (CES) has long been recognized as a rare complication of spinal anesthesia.(1) CES has been described after administration of spinal anesthetics with lidocaine(2) and bupivacaine.(3) In 1991,(4) CES was reported after continuous spinal anesthesia with 1% tetracaine. In 1980, at our university hospital, six adult female patients underwent perineal gynecologic surgery using a spinal anesthetic of 2 ml tetracaine, 1.2%, in 10% glucose. The concentration of the injected tetracaine was unknown by the anesthetists. In all cases, lumbar puncture was performed at the L3-L4 interspace with a disposable spinal needle while the patients were in the sitting position. CES was first diagnosed 72 h or later postoperatively; previous diagnosis was not possible because patients had an indwelling urethral catheter. The diagnosis of CES was confirmed in all patients. During the past year, after institutional approval and informed consent, clinical, magnetic resonance imaging, electromyographic examinations, and conduction studies were performed in three of the above patients. Examinations were not possible on the other three patients because one had recently died, another could not be located, and the third refused to participate. T1 and T2 magnetic resonance image readings were obtained with Gadolinium contrast from a 0.5 Tesla General Electric apparatus (General Electric, Tokyo, Japan). Bilateral sensory and motor conduction studies of the sciatic nerve branches were obtained using a two-channel Nihon-Kohden Neuropack 2 (Nihom-Kohden Corporation, Tokyo, Japan). Electromyography was performed in accordance with conventional techniques.(5,6)

Estudo das alterações cariotípicas, do rearranjo gênico BCR/ABL e do cromossomo 20 em leucemias

Leukemia is a genetic disease from a noncontrolled abnormal process of the hematopoietic cells' differentiation and proliferation. Some alterations of structure and number of chromosomes have been well and specifically observed in leukemia. The detection of these alterations is highly significant in providing the patients' diagnosis, prognosis and treatment as well as the understanding of the genetic bases of this disease. The purpose of this work is to study some chromosomal alterations in peripheral blood and/or bone marrow in patients with different leukemia types by means of conventional cytogenetic techniques, and also to investigate the presence of BCR/ABL gene rearrangement and some alterations in chromosome 20 by the FISH technique. Samples of peripheral blood and/or bone marrow of 28 patients, who were not under chemoor radio-therapeutic treatment, were studied: 15 with CML, 11 with AML and 2 with ALL. The alteration most frequent was t(9;22) in the CML, whose presence or absence was related to a good or bad prognosis, respectively. A case of AMI showed inv(16)(p13q22), related to a good prognosis. Some alterations not reported previously in the literature were found, such as the trisomy in chromosome 2 associated to chromosome Ph showing some disease progress in one of the CML cases and t(5;16)(q13;q22) in an AML patient. One of the cases was submitted to an allogeneic hone marrow transplant. The monitoring after the 23 rd day of transplant, detected 95% of the donor cells suggesting the procedure had succeeded. Two patients, an AMI and the other ALL, showed trisomy of chromosome 20 in the neoplastic cells. The results showed the importance of the cytogenetic analysis in relation to leukemia, its direct benefits to the patients and the biological mechanisms involved in this disease. They also allowed the introduction in the Genetic Service of FAMERP techniques to obtain the bone marrow metaphases and the FISH technique.
