Malignant hyperthermia caused by intravenous lidocaine for ventricular arrhythmia.

We encountered a case of malignant hyperthermia caused by intravenous lidocaine which had been administered as treatment for a ventricular arrhythmia. The patient, a 72-year-old male, was admitted with chronic renal failure and aortic valvular stenosis. His chronic renal failure progressed, and congestive heart failure developed, and ventricular arrhythmias occurred frequently. For the treatment of these arrhythmias, lidocaine was injected and continuous infusion was started. Despite initial improvement in symptoms and laboratory data following hemofiltration, refractory ventricular tachycardia occurred. The patient was treated with large doses of lidocaine. His body temperature rose to a maximum of 41.7 degrees C, and generalized muscular twitching was observed before he lost consciousness. Serum and urinary myoglobin levels became elevated. This abnormally high fever was relieved only by dantrolene sodium. After we made a diagnosis of malignant hyperthermia and stopped the lidocaine infusion, the high fever resolved quickly. It is important to note that malignant hyperthermia can be caused by lidocaine and amide-linked local anesthetics.

[A successfully treated case of acute renal failure due to acute immune hemolytic anemia and nontraumatic rhabdomyolysis induced by streptomycin reinjection].

A case of acute immune hemolytic anemia associated with non-traumatic rhabdomyolysis (NTR) induced by streptomycin (SM) reinjection, which developed acute renal failure, has been reported. A 70-year-old female was admitted to our hospital because of sudden macroscopic hematuria after reinjection of 1g. SM. Laboratory findings on admission were as follows; hemoglobin and myoglobin were positive in urine. RBC 129 x 10(4)/microliters, Hb 4.9g/dl, Ht 11.1%, reticulocytes 52/1000, serum indirect billirubin 3.8g/dl, LDH 9, 230 WU, BUN 149mg/dl, Cr 7.9mg/dl, myoglobin 1, 400ng/ml and haptoglobin 10.6mg/dl. The drug lymphocyte stimulating test of SM was positive (215%). A direct antiglobulin test was also positive. An indirect antiglobulin test was negative, but became positive after incubation with SM. These observations made the diagnosis of SM-induced hemolytic anemia associated with NTR. On the second hospital day she developed anuria, and was put on hemodialysis treatment. Two months after the acute hemolytic episode and acute renal failure she recovered and is presently in good health without recurrence.

Catalytic site of F1-ATPase of Escherichia coli. Lys-155 and Lys-201 of the beta subunit are located near the gamma-phosphate group of ATP in the presence of Mg2+.

The catalytic site of Escherichia coli F1 was probed using a reactive ATP analogue, adenosine triphosphopyridoxal (AP3-PL). For complete loss of enzyme activity, about 1 mol of AP3-PL bound to 1 mol of F1 was estimated to be required in the presence or absence of Mg2+. About 70% of the label was bound to the alpha subunit and the rest to the beta subunit in the absence of Mg2+, and the alpha Lys-201 and beta Lys-155 residues, respectively, were the major target residues (Tagaya, M., Noumi, T., Nakano, K., Futai, M., and Fukui, T. (1988) FEBS Lett. 233, 347-351). Addition of Mg2+ decreased the AP3-PL concentration required for half-maximal inhibition, and predominant labeling of the beta subunit (beta Lys-155 and beta Lys-201) with the reagent. ATP and ADP were protective ligands in the presence and absence of Mg2+. The alpha subunit mutation (alpha Lys-201----Gln or alpha Lys-201 deletion) were active in oxidative phosphorylation. However, purified mutant F1s showed impaired low multi-site activity, although their uni-site catalyses were essentially normal. Thus alpha Lys-201 is not a catalytic residue, but may be important for catalytic cooperativity. Mutant F1s were inhibited less by AP3-PL in the absence of Mg2+, and consistent with this, modifications of their alpha subunits by AP3-PL were reduced. AP3-PL was more inhibitory to the mutant enzymes in the presence of Mg2+, and bound to the beta Lys-155 and beta Lys-201 residues of mutant F1 (alpha Lys-201----Gln). These results strongly suggest that alpha Lys-201, beta Lys-155, and beta Lys-201 are located close together near the gamma-phosphate group of ATP bound to the catalytic site, and that the two beta residues and the gamma-phosphate group become closer to each other in the presence of Mg2+.

Advanced gastric cancer associated with acute myelocytic leukemia--report of a case.

A case of advanced gastric cancer associated with acute myelocytic leukemia (AML) is reported. Synchronous double malignancies of gastric cancer and AML are very rare. Combination chemotherapy (BHAC-DMP) was used as the method for induction and consolidation therapy for AML and a complete remission was obtained. However, it failed to show any therapeutic effect on the gastric cancer. A radical subtotal gastrectomy was performed with lymphadenectomy. During the postoperative course, both respiratory failure and severe thrombocytopenia progressed. Fortunately, the patient responded well to mechanical ventilation and the administration of heparin. She was discharged on day 52 after surgery, and no sign of recurrence of either gastric cancer or AML has been observed over the one-year period following the gastrectomy. In principle, in order to achieve a good prognosis, a radical resection should be carried out for gastric cancer associated with AML. However, chemotherapy for AML might make the patient vulnerable to surgical stress, although we could not demonstrate any concrete evidence which could prove the impairment of host immunity in this case. It is, therefore, possible that not only the relapse of AML but also the impairment of host immunity may cause some other difficulties during the post-gastrectomy course.

Epstein-Barr virus activating principle in husbands' semen of cervical cancer patients.

A short-term in vitro assay for detecting tumor promoter activity has been cultivated utilizing the induction of Epstein-Barr virus early antigen (EBV-EA) in EBV genome-carrying human lymphoblastoid cell line (Raji cell) system. By using this system, we found that some of human semen samples possessed a marked capacity to induce EBV-EA, suggesting possible tumor promotor activity of semen. In the present study, 60 semen samples obtained from husbands of cervical cancer patients and 90 control samples were incubated with Raji cells for 48 h, and EBV-EA-expressing cells detected by indirect immunofluorescence were counted. The percentages of EBV-EA-positive cells treated with semen of cervical cancer patients' husbands (8.17 +/- 5.43%) were significantly higher than those of controls (5.23 +/- 5.91%). Since most of EBV-EA expressing effect on Raji cells show overlapping with tumor promotor activities, our present results implies the circumstantial association of seminal EBV-EA inducing activity with occurrence of human cervical cancer.

[Maintenance of housewife activity and the quality of familiar interactions by home continuous infusion chemotherapy in patients with recurrent gynecological cancer].

Sixteen patients with recurrent gynecologic cancer were studied to evaluate maintenance of housewife activity and the quality of familiar interactions by the home continuous infusion of CDDP at a daily dose of 5 mg/body. A total dose of CDDP in one course was 100 mg/body, and more than one course was performed in every patient. Eight patients underwent intra-arterial infusion of CDDP by the 20-day continuous infusion and another 8 patients intra-venous infusion by 5-day continuous infusion every other week. The average caloric intake was 2201 kcal measured by the record of a three-day food intake during the treatment. 88% of the patients arouse between 6 and 7 in the morning, and all the patients cooked breakfast and supper, went shopping for food materials, cleaned a house and did the washing with the help of her family. All the patients accepted the treatment and were satisfied with it but appeared anxious about recurrence. Information or advice by the doctor was important to relieve their anxiety. Their husbands also accepted the treatment and tolerated well their wives, continuation of home therapy.

Irregular isoantibodies in the sera of patients undergoing chronic hemodialysis.

We screened 89 patients undergoing chronic hemodialysis for irregular isoantibodies. Irregular isoantibodies were detected in six patients (6.7%). This is an extremely high percentage compared with previous reports, considering that the presence of irregular isoantibodies was estimated to be 2.91% in multiparas, in whom they were found most frequently. This may be due to the fact that hemodialysis patients often receive blood transfusions but it also suggests that hemodialysis per se may induce the production of irregular isoantibodies. The blood-group specificities of the irregular isoantibodies detected were anti-N, anti-Leb + anti-HI, anti-Lea + anti-Leb, anti-H and anti-I, anti-P1, anti-rh" (E). The majority of the cases with irregular isoantibodies were examined because of clinical problems during hemodialysis. Therefore, we checked for the presence of irregular isoantibodies before the induction of hemodialysis and every three to six months thereafter.

The glycine-rich sequence of the beta subunit of Escherichia coli H(+)-ATPase is important for activity.

A short sequence motif rich in glycine residues, Gly-X-X-X-X-Gly-Lys-Thr/Ser, has been found in many nucleotide-binding proteins including the beta subunit of Escherichia coli H(+)-ATPase (Gly-Gly-Ala-Gly-Val-Gly-Lys-Thr, residues 149-156). The following mutations were introduced in this region of the cloned E. coli unc operon carried by a plasmid pBWU1: Ala-151----Pro or Val; insertion of a Gly residue between Lys-155 and Thr-156; and replacement of the region by the corresponding sequence of adenylate kinase (Gly-Gly-Pro-Gly-Ser-Gly-Lys-Gly-Thr) or p21 ras protein (ras) (Gly-Ala-Gly-Gly-Val-Gly-Lys-Ser). All F0F1 subunits were synthesized in the deletion strain of the unc operon-dependent on pBWU1 with mutations, and essentially the same amounts of H(+)-ATPase with these mutant beta subunits were found in membranes. The adenylate kinase and Gly insertion mutants showed no oxidative phosphorylation or ATPase activity, whereas the Pro-151 mutants had higher ATPase activity than the wild-type, and the Val-151 and ras mutants had significant activity. It is striking that the enzyme with the ras mutation (differing in three amino acids from the beta sequence) had about half the membrane ATPase activity of the wild-type. These results together with the simulated three-dimensional structures of the wild-type and mutant sequences suggest that in mutant beta subunits with no ATPase activity projection of Thr-156 residues was opposite to that in the wild-type, and that the size and direction of projection of residue 151 are important for the enzyme activity.

[A case of idiopathic plasmacytic lymphadenopathy with polyclonal hyperimmunoglobulinemia associated with chronic renal failure].

A rare case of idiopathic plasmacytic lymphadenopathy with polyclonal hyperimmunoglobulinemia (IPL) associated with chronic renal failure was described in this report. A 73-year-old male was admitted and diagnosed as IPL. IPL is proposed by Mori et al. in 1980. Clinical entity of IPL is (1) Polyclonal hyperimmunoglobulinemia (2) Systemic Lymphadenopathy characterized by remarkable mature plasmacytosis without atypism and by no destruction of the structures. (3) All disease with polyclonal hyperimmunoglobulinemia can be excluded. In this patient, physical findings showed enlarged lymph nodes (1-2 cm) in bilateral nuchal, submandibular, axillary and inguinal lesions. Laboratory examinations showed polyclonal hyperimmunoglobulinemia (especially IgG, IgA), anemia and renal dysfunction. Microscopic observation of hematoxylin-eosin staining in the axillary lymph node showed increased mature plasma cells without evidence of malignant growth. Immunoperoxidase staining showed intracytoplasmatic polyclonal immunoglobulins. IPL is known as invading other organs besides lymph node, for example skin, lung or kidney. This patient showed renal dysfunction (Cr clearance 11 ml/min, severe proteinuria). Nine cases of IPL and multicentric plasma cell type Giant Lymphnode Hyperplasia (GLH) concurrent with renal dysfunction were reported. Only in two of them chronic renal failure were reported. Twice a week hemodialysis improved his condition and laboratory findings.
