ENACTMENT: SOME THOUGHTS ABOUT THE THERAPIST'S CONTRIBUTION

ABSTRACT This paper examines three instances of enactment, which occurred in the early stages of a thrice-weekly therapy. The emphasis is on both the origins and consequences of the therapist's contribution. Particular attention is paid to the unconscious nature of enactment, as a phenomenon that can precipitate both a refusal and an actualization of the patient's transference; the former, in this case, leading to further acting out and the latter to malignant regression.     

Treatment of refractoriness to platelet transfusion by protein A column therapy

Ten thrombocytopenic patients (platelets < 10–24 × 10(9)/L) who were refractory to platelet transfusion were investigated for their responsiveness to staphylococcal protein A column therapy. Nine patients had previously been treated with steroids, intravenous immune globulin, and/or other forms of immunosuppressive therapy without improvement in their transfusion response. All patients were receiving multiple platelet transfusions without achieving 1-hour corrected count increments (CCIs) > or = 7500. Eight patients had antibodies that reacted with platelets and were directed against HLA class I antigens, ABO antigens, and/or platelet-specific alloantigens. Plasma (500-2000 mL) from each patient was passed over a protein A silica gel column and then returned to the patient. Patients received from 1 to 14 treatments. A positive response to protein A therapy was defined as at least a doubling of the pretreatment platelet count and/or two successive 10- to 120-minute posttransfusion CCIs > or = 7500. Following plasma treatments, 6 of 10 patients responded with daily platelet counts that averaged 48 +/− 11 × 10(9) per L as compared with counts of 16 +/− 7 × 10(9) per L (p < 0.0005) before treatment. Posttransfusion CCI values determined in four of these patients averaged 2480 +/− 810 and 10,010 +/− 3540 (p < 0.005) before and after treatment, respectively. In contrast, among the four unresponsive patients, platelet counts averaged 10 +/− 9 and 13 +/− 10 × 10(9) per L (p = NS), respectively, while posttransfusion CCIs were 700 +/− 1410 and 1520 +/− 2460 (p = NS), respectively.(ABSTRACT TRUNCATED AT 250 WORDS)     

Therapy associated leukaemia.

A dose related risk of acute leukaemia, myelodysplasia and other cancers is seen in patients treated with certain drugs, particularly alkylating agents, and radiotherapy either alone or in combination. Treatment associated acute myeloid leukaemia (tAML) and myelodysplasia have biological and clinical features in common and are distinct from the corresponding de-novo disorders. tAML generally occurs between 2-11 years from administration of chemo/radiotherapy with few cases thereafter. Patients may present with myelodysplasia and severe cytopenia with abnormalities in all cell lines or as an acute leukaemia which may be difficult to classify because of multi-lineage involvement. Clonal cytogenetic abnormalities usually including either loss or interstitial deletion of the long arm of chromosomes 5 or 7 are frequently identified. Critical regions deleted in all patients with these lesions have been localised at 5q23-32 and 7q22-31; regions carrying the genes for several haemopoietic growth factors, receptors and oncogenes. The prognosis of patients with tAML is poor with low remission rates and a median survival of 6 months. Complex karyotypes or lesions of chromosomes 5 or 7 seen in the majority of cases are associated with a particularly poor outlook. The risks of this most serious complication of therapy should be weighed carefully against possible benefits.     

Perforated colorectal neoplasms: correlation of clinical, contrast enema, and CT examinations

Results of clinical, contrast enema (CE), and computed tomographic (CT) examinations in 39 patients with perforated colorectal neoplasms were retrospectively reviewed. Twenty patients were toxemic at initial presentation, but in only four patients was the diagnosis of perforated colorectal neoplasm initially suspected clinically. CE study was performed in 22 patients and enabled the diagnosis of perforated neoplasm in 11 cases, neoplasm alone in eight, and neither neoplasm nor perforation in three. CT was performed in 38 patients and enabled the diagnosis of perforated neoplasm in 36; pericolic phlegmon but no mass lesion was evident in two. In 16 patients, CT also demonstrated metastatic disease. Because of its reliability in establishing the diagnosis and staging the extent of the inflammatory and neoplastic disease, CT is indicated in cases of suspected or proved perforated colorectal neoplasm and in cases in which CE study findings are indeterminate or suggestive of perforated neoplasm.     

The favoured child?

This case conference concerns a child who has been in care following a diagnosis of emotional abuse and a serious incident of physical abuse. She wants to return home again, and her parents, who had previously scapegoated her, now blame the family''s previous ills on her sister instead. The Children Act 1989 gives considerable weight to the child''s wishes, but what if the child returns home and is re-abused? In this case conference a child psychiatrist, a philosopher and a lawyer discuss the issues of clinicians'' responsibilities, moral luck, and child care law.     

The effect of interleukin-2 administration on wound healing in adriamycin-treated rats

Adriamycin (doxorubicin hydrochloride), an effective chemotherapeutic drug, is also a potent inhibitor of wound healing. Conversely, certain polypeptide growth factors are capable of stimulating fibroblasts to secrete collagen, thus enhancing wound healing. The purpose of this study was to determine if interleukin-2 (IL-2), a T-cell growth factor, could reverse the wound healing deficit caused by Adriamycin. Adriamycin treatment caused a significant decrease in wound-breaking strength (P less than 0.005). IL-2 administration increased wound-breaking strength in Adriamycin-treated animals (2126 g vs 1549 g, P less than 0.005). In control animals, IL-2 did not increase wound-breaking strength significantly (2708 g vs 2608 g, P greater than 0.1). Histologically, wounds from Adriamycin-treated animals were less cellular, demonstrated less collagen in the dermis, and a lesser degree of capillary ingrowth. The number of fibroblasts in the dermal layer was increased in animals receiving IL-2. Control rats gained an average of 1.4% of their original body weight, while Adriamycin-treated rats lost an average of 19% of their original body weight (P less than 0.0005). IL-2 administration did not influence weight loss or gain. Hematologically, animals receiving Adriamycin had lower hemoglobin and hematocrit values and higher platelet counts. There were no differences in total white blood cell counts; however, animals receiving Adriamycin showed a predominance of polymorphonuclear leukocytes and a relative decrease in lymphocytes. Animals receiving IL-2 demonstrated a significant eosinophilia. (1) Adriamycin impairs normal wound healing. (2) Interleukin-2 administration improves the wound healing impairment caused by Adriamycin. (3) Interleukin-2 appears to increase infiltration of inflammatory cells, fibroblasts, and capillaries into the wound, which may account for the observed increase in wound breaking strength.
