AIDS related mortality has fallen sharply in industrialised countries since 1996 following the introduction of highly active antiretroviral therapy. This has been accompanied by an increase in the proportion of deaths attributable to non-AIDS defining solid tumours, especially lung cancer. The risk of developing lung cancer seems to be higher in HIV infected subjects than in the general population of the same age, partly because the former tend more frequently to be smokers and, especially, intravenous drug users. The carcinogenic role of the antiretroviral nucleoside drugs and their interaction with smoking needs to be examined. Interestingly, there is no clear relationship between the degree of immunosuppression and the risk of lung cancer, so the reason for the increased risk is unknown. The mean age of HIV infected patients at the time of lung cancer diagnosis is 45 years and most are symptomatic. Lung cancer is diagnosed when locally advanced or metastatic (stage III-IV) in 75-90% of cases, similar to patients with unknown HIV status. Adenocarcinoma is the most frequent histological type. The prognosis is worse in HIV infected patients than in the general lung cancer population. Efficacy and toxicity data for chemotherapy and radiation therapy are few and imprecise. Surgery remains the treatment of choice for localised disease in patients with adequate pulmonary function and general good health, regardless of immune status. Prospective clinical trials are needed to define the optimal detection and treatment strategies for lung cancer in HIV infected patients.

The authors describe the advantages of self-psychological concepts in the treatment of combat veterans with posttraumatic stress disorder (PTSD). Classical psychoanalytic views of PTSD opened the door to understanding PTSD as a type of "narcissistic neurosis." Although many psychological and psychoanalytically oriented treaters of PTDS acknowledge that the entire personality needs rehabilitation and, thus, a comprehensive approach to the PTSD patient is indicated, most stay close to the primacy of pathological memory. Self psychology, with its specific view on damage and repair of the self and the key importance of the selfobject transference in that process, provides a focus wherein damage to the self comes first and alterations in other psychological systems take on an important but secondary emphasis. The authors outline the central elements of PTSD in combat veterans and review the contributions of psychoanalysis to their treatment. Core concepts from self psychology are detailed, and three vignettes of veterans treated in an outpatient PTSD clinic are offered to illustrate the specific mirroring, idealizing, and twinship selfobject transferences they bring to the treatment situation. Finally, a discussion of each vignette highlights how self psychology's focus on strengthening the damaged self has aided in patients' improvement.
Although men and women show similar rates of obesity, women more frequently engage in weight loss efforts, with potentially adverse health consequences. We surveyed 320 college-aged men and women to examine gender differences in the determinants of body dissatisfaction and the degree of importance assigned to bodyweight and shape. Results indicated that, for both genders, satisfaction with bodyweight and shape decreased as body mass index (BMI) increased. Women, however, showed significantly greater body and weight dissatisfaction than men at most weight categories. Only the underweight (BMI < 20) women and men were similarly satisfied with their bodyweight and shape. As BMI increased, however, women became disproportionately more dissatisfied: both normal-weight and overweight women expressed greater dissatisfaction than comparable men. College-aged women also attributed progressively more importance to both weight and shape as BMI increased, unlike college-aged men, who considered body weight equally important to (or slightly less important than) self-esteem as BMI increased. We discuss implications for the self-esteem of obese women and men.
Dens in dente is a developmental anomaly, which, in some advanced cases, requires a combination of conventional and surgical endodontic treatment. The purpose of this article is to suggest how to treat a Type 3 (Oehlers classification) dens in dente.
The concept of the container has a place within cognitive science as well as within psychodynamic theories. Cognitive semantics has shown that many metaphors giving meaning to daily life-events use the container as a basic reference point. Psychoanalytic theory, most notably, Freud's psychosexual developmental model, illustrates how the container of the body results in meaning. Object relations theory in psychoanalysis has shown how patients with borderline personality disorder behave according to the dynamics of container and containment. Both the cognitive and the psychodynamic conceptions of containers are clinically relevant. The fundamental notion of the container leads to an exploration of 'container dynamics' both in cognitive semantics and in psychodynamic work. A model of the cusp may be of help in the description of the dynamics at the border of the container. Furthermore, the descriptions of the patient's communication of emotion and thoughts may involve three interacting dimensions: an effective-perceptual dimension, a phantasy dimension and a socio-interactive dimension. The interaction between these dimensions has implications for dealing with container dynamics and the process of containment.
Paranoid phenomena can be seen to arise from pathological narcissism. As a result of certain kinds of trauma to the ego-ideal and/or losses of important self-object relationships, the self becomes dislodged from internal agencies and representations. Narcissistic cathexis of the self to these internal psychic structures loosens and hope, aspiration, affection and will become markedly diminished. Meaningful goals and choices become impossible to adopt and make. The paranoid patient is internally at "loose ends"; he is lost. Tragically, being gripped by the paranoid condition and its manifest delusional system is the only kind of security that the paranoid patient knows. No wonder it is so hard to give up. The vulnerability to paranoid phenomena may be seen to be a result of past experiences of subversion of "selfhood." In significant ways, the patient vulnerable to paranoid phenomena has not been adequately attended nor adequately "left alone." The self can be seen as arising out of crucial mother-infant exchanges that are paralleled by interactions between developing internal psychic structures. Out of these "reflections," the self is born. The narcisstic cathexis of self to the ego, superego and ego-ideal is the result of self-expression. If full self-ownership has not been possible then self-expression is vulnerable. Given these understandings of the relationship between paranoid phenomena and pathological narcissism, treatment will focus on reducing the threats to selfhood, refinding the self, and reestablishing ties to internal sources of affection, initiative and aspiration.
Fifty-six patients with advanced metastatic carcinoma of the breast, melanoma and lymphoma were treated with the new vinca alkaloid vindesine in a prospective Phase II study. The dose was 3 mg/M2 by I.V. bolus once a week for a minimum of two doses. Patients who failed to respond to four I.V. doses were treated with 48-h intravenous infusions at a dose of 1.5 mg/M2 per 24 h. Of the 26 evaluable patients with breast cancer, there were only two incomplete responses and four patients who experienced stabilization of disease. Of the 12 evaluable patients with melanoma, no responses were seen with four patients experiencing stabilization of disease. Of the 11 patients with non-Hodgkin's lymphomas, there was one complete remission which persisted for 26 months and two partial remissions. No additional responses were seen when the mode of administration was changed to 48-h infusion in three patients with breast cancer, five patients with melanoma and one patient with lymphoma. Significant toxicities included neutropenia in 24 patients and nausea and vomiting in two patients. There were no drug related deaths. Previously reported experience with vindesine in these tumors is reviewed as well.
21 patients with metastatic breast cancer, refractory to conventional agents, were treated with a combination of BCNU, vincristine, mitomycin-C and prednisone given every 4 weeks. Only three of the nineteen (15.8%) evaluable patients were observed to have a partial remission, whereas four experienced stabilization of tumor. The sites which responded included skin lesions in two patients and a pleural effusion in 1 patient. This combination resulted in moderate to severe thrombocytopenia in five patients, but was otherwise well tolerated. This pilot study therefore suggests that these four agents in the schedule and doses given do not appear to be superior to any of these agents used singly for advanced, refractory breast cancer.
2 patients developed the nephrotic syndrome several years after diagnoses of chronic lymphocytic leukemia. In both cases light microscopy showed membranoproliferative glomerulonephritis. Electron microscopy and immunofluorescent staining revealed electron-dense deposits and deposition of immunoglobulins and C3. Both patients had single-component IgG cryoglobulinemia. The eluted glomerular-bound protein contained IgG only. IgG in patients' sera, cryoglobulins, and kidney eluate had kappa light chains only. Immune complexes were detected in the sera and in the cryoglobulins by the Clq binding test. Immunoadsorption studies revealed anti-IgG antibodies in the patients' sera, cryoglobulin, and kidney eluate. Direct immunofluorescent studies using the patients' sera, cryoglobulins, and kidney eluate on frozen sections of patients' kidneys were positive, providing additional evidence for the immune complex nature of the glomerulonephritis. The immunohistochemical studies of our patients are suggestive of the presence of circulating IgG-anti-IgG immune complexes and their possible involvement in the pathogenesis of the glomerulonephritis and the nephrotic syndrome in these 2 cases.
