Recurrent neuroleptic malignant syndrome due to tiapride and haloperidol: the possible role of D-2 dopamine receptors.

Two typical recurrent episodes of neuroleptic malignant syndrome (NMS) in the same patient are described. The first episode was caused by a sulpiride derivative, tiapride. This is the first case in which a drug of the benzamide group has been reported to have caused such adverse drug reaction. In the second episode, NMS occurred due to haloperidol in the lowest dose ever reported and was accompanied by highly excessive levels of various muscle enzymes. Involvement of hypothalamic and striatal dopamine system, and particularly of D-2 subtype receptors, is suggested by this case.

Herpes zoster and small cell bronchogenic carcinoma.

In nine of 74 (12 per cent) consecutive, previously untreated patients with small cell bronchogenic carcinoma receiving combination chemotherapy herpes zoster developed. This is the highest frequenzy reported for this viral infection in patients with nonlymphoproliferative solid tumors. Cutaneous dissemination developed in six of the nine patients, but visceral involvement did not occur. The major difference between the patients with herpes zoster and those without was the superior duration of median survival for the infected patients. No relationship could be established between the development of herpes zoster and the extent of neoplastic disease, prior radiotherapy, treatment with specific chemotherapeutic agents or corticosteroids, cutaneous anergy or granulocytopenia. Serum specimens obtained from six of the nine patients prior to their infection demonstrated the preexistence of varicella zoster antibodies. As more effective and intensive chemotherapy prolongs the survival of patients with solid tumors, it is possible that the frequency of herpes zoster infection may approach that observed in patients with lymphoproliferative malignancies.

Purification and properties of the latent F1-APTase of Micrococcus lysodeikticus.

The latent coupling factor (F1)-ATPase of Micrococcus lysodeikticus has been purified to homogeneity as determined by a number of criteria including, nondenaturing polyacrylamide gel electrophoresis, crossed immunoelectrophoresis and analytical ultracentrifugation. By inclusion of 1 mM phenylmethyl sulfonyl fluoride, a serine protease inhibitor, in the shock-wash step of release of F1 from the membranes, the spontaneous activation of both crude and purified ATPase by endogenous membrane protease(s) can be prevented, thereby yielding a highly latent ATPase preparation. Equilibrium ultracentrifugation of the latent ATPase gave a molecular weight of 400 000. The ATPase contained five different subunits alpha, beta, gamma, delta, and espsilon and their molecular weights determined by SDS-polyacrylamide gel electrophoresis were 60 000, 54 000, 37 000, 27 000 and 9000, respectively. The subunit composition was determined with 14C-labelled, F1-ATPase prepared from cells grown on medium containing [U-14C]-labelled algal protein hydrolysate. Within the limitations of this method the results tentatively suggest a subunit composition of 3 : 3 : 1 : 1 : 3.

Efficacy of multimodality therapy in gastric adenocarcinoma.

Multimodality therapy has not reproducibly improved the survival of patients with gastric adenocarcinoma. This is largely because the staging of disease has been imprecise and because the current regimens have only limited efficacy against advanced disease. Until staging is improved and active regimens are found, it will be difficult to identify synergism between surgery and other treatment modalities.

Influence of multimodality therapy on the management of pancreas carcinoma.

Carcinoma of the pancreas has an especially grim prognosis. Only 1-3% of patients survive for 5 years. Radical pancreaticoduodenectomy, especially for minimal disease, is currently the only chance for cure. While radiation therapy does not improve overall survival, it may improve local control following radical resection and decrease pain in locally advanced cancers. Although chemotherapy has led to significant improvements in survival in patients with locally advanced disease, the overall effect is small. When surgery, radiotherapy, and chemotherapy are administered to localized carcinomas in randomized, prospective trials, survival is significantly lengthened. Similar trials in locally advanced, unresectable pancreatic cancer also confirm the concept of synergistic interaction between therapies. Thus, pancreas carcinoma is one neoplasm where multimodality therapy has had a demonstrable, although small effect.

Impact of combined modality therapy on the treatment of adenocarcinoma of the colon.

An emphasis on careful surgical staging of adenocarcinoma of the colon has improved the predictive value of tumor staging systems. As a result of improved staging and carefully conducted randomized clinical trials, adjuvant therapy of locally advanced colon cancer, based on 5-fluorouracil chemotherapy, has been proven to substantially reduce recurrence rates and significantly increase overall survival for selected patients. Improved treatments and schedules are currently being studied in randomized trials and may increase the efficacy of this adjuvant therapy. Radiation therapy has not as yet been integrated into the adjuvant treatment of colon carcinoma. The application of a combined approach of surgery and chemotherapy in selected patients with liver metastases may also improve cure rates and long-term survival. The developing understanding of molecular determinants for the biological behavior of these cancers will increase the opportunities to identify, on the one hand, those patients who will benefit from specific therapies, and, on the other hand, new therapeutic strategies and treatments.
