[Tuberculosis in the immunodepressed patient].

Tuberculosis is one of the opportunist infections which may complicate the course of many immunodepressive conditions generally those affecting cell-mediated immunity as the Koch bacillus is an organism which develops intracellularly provoking the activation of the cellular type of defence reaction. Recently, patients with malignant disease and immunosuppressive therapy have been joined by those with the acquired immunodepressive syndrome. It is important to understand that the frequency of tuberculosis in immunodepression is a reflection of the frequency of the disease in the general population. In addition, the diagnosis of atypical forms of tuberculosis can be difficult: the presenting signs are not specific and extrapulmonary forms are common. Therefore, tuberculosis should be suspected whenever immunodepressed patients develop unexplained symptoms. All practical means of confirming the diagnosis should be employed and the patient given a course of antituberculous drugs if there is any doubt as early treatment is an important prognostic factor.

[Evaluation of the prevalence of pathology of drug origin in a department of internal medicine].

The authors report the results of a one year study carried out in the Department of Internal Medicine at Laennec Hospital. Out of a total of 1334 hospitalisation, 95 had drug side effects (7.1 p. 100) and 3.5 p. 100 of admissions were directly related to a iatrogenic complication. These complications were more common in women and elderly patients. Sixty-two drugs were implicated: antibiotics (32.6 p. 100), cardiovascular drugs (20 p. 100) including the diuretics (8.4 p. 100), antiinflammatory and antalgic drugs (16.8 p. 100), anticoagulants (8.4 p. 100), neuropsychiatric drugs (7.4 p. 100), oral hypoglycaemic agents (6.3 p. 100)..., 101 side effects were observed: gastro-intestinal (35.6 p. 100) dermato-anaphylactic (19.8 p. 100), cardiovascular (12.9 p. 100), endocrine or metabolic (11.8 p. 100), neuropsychiatric (10.9 p. 100), haematological (5.9 p. 100) and renal (4.2 p. 100). Iatrogenic complications were responsible for the admission to hospital of 47 patients and for 390 days of hospitalisation, costing approximately 380.000 FF.

[Malignant histiocytosis of pulmonary form].

Malignant histiocytosis beginning by a unique pulmonary location is most unusual. The case reported here has seemed worthy because of its strange clinical aspect, the unexpected diagnosis, and because of the way it answered completely and rapidly to the following chemotherapy: Adriamycin 50 mg/m2, Cyclophosphamide 750 mg/m2, Vincristine 2 mg one day every three weeks associated to Prednisone 100 mg/m2 the five first days. A study of literature has allowed us to review all pleuro-pulmonary location initiating malignant histiocytosis and to stress out the errors of diagnosis that can outcome in this case.

[Communication in functional and dysfunctional families with adolescent children. II. Nonverbal communication].

This research focuses on family communications during the critical period of children's puberty provoked change. Two groups of families are compared: one group of 15 "functional" families (no psychological counseling has been requested) and one group of 15 "dysfunctional" families (a psychological counseling has been requested for one of the adolescents). The micro-analysis of the non-verbal communication reveals structural differences between the family systems. This fits with the differences revealed by the analysis of the verbal communications.

[Communication in functional and dysfunctional families with adolescent children. III. Evaluation of the relation of verbal and nonverbal communications].

This study analyzes communication in families with one or more adolescent children, thus undergoing a critical period of transition. Two groups are compared: a group of 11 "functional" families (no child referral for psychological problems) and a group of 11 "dysfunctional" families (one adolescent child referral for psychological problems). The analysis of relationships between verbal and non-verbal communication indicates that more inter-channel congruence is achieved in "functional" families; this holds for individual as well as for inter-partners interactions. The results of the previously published separate analysis of verbal and non-verbal communication are briefly resumed. The findings of the study as a whole are interpreted in terms of the General Systems Theory with regard to the function of "parental framing" of the child's development.

Blood type A and familial breast cancer.

The association between blood type A and breast cancer was evaluated in 648 patients with family histories of the disease, 1897 unselected patients, 4577 institutional blood donor controls, and 14,508 extramural blood donor controls. The familial patients were classified into three pedigree groups in which the lifetime breast cancer risks to first-degree relatives ranged from 11% to 32%. In the pedigree group associated with a relatively low risk to relatives, the authors saw a significant excess of blood type A individuals when compared with either control group. The unselected patient population, which was considered to refer to a general series of patients, also showed an excess of blood type A individuals with either control but a significant excess only in comparison with institutional controls. Patients from high-risk pedigrees with inherited forms of breast cancer showed no association when compared with either control group. The effect of blood type A on breast cancer risk was considered too small to be of use in identifying women at high risk. The results further suggested that the effect of blood type A on breast cancer development was capable of being masked by the effect of breast cancer susceptibility genes and/or that the inherited and noninherited types involve different etiologic mechanisms.

Cancer mortality in relatives of retinoblastoma patients.

The risk of other cancers in relatives of retinoblastoma (RTB) patients was determined by a survey of the mortality experience of siblings, parents, parental siblings, and grandparents of all U.S. or Canadian RTB patients referred to The University of Texas M.D. Anderson Hospital and Tumor Institute between 1944 and 1980. Expected mortality was ascertained by the application of age-, sex-, race-, and calendar year-specific U.S. mortality rates to the observed person-years. Among 607 relatives of 33 unilateral-sporadic RTB probands, no excess in cancer deaths was observed (observed/expected = 18/22). Among 733 relatives of 47 bilateral-familial RTB probands, a slight excess in cancer deaths was observed (41/31). A significant excess in cancer deaths was occurred in relatives under age 55 years (18/9) and in fathers (7/1) of the bilateral RTB probands. To determine whether the cancer excess was related to some unique allele associated with second tumors in RTB survivors, the cancer mortality of 203 relatives of the 14 RTB patients with second tumors was examined, and no excess was observed (11/11). To determine whether the excess might be attributable to an unexpressed RTB gene or precursor, the mortality experience was examined in 6 kindreds in which parents, unaffected by RTB, had more than 1 child with RTB. Among these 72 relatives a significant excess in cancer deaths was observed (8/2). The findings demonstrate a modest overall cancer excess in relatives of hereditary RTB patients and suggest it may be attributable to an unexpressed RTB gene or precursor in a small number of kindreds. Mechanisms for an apparent "precursor" might involve a delayed mutation, genetic mosaicism, or a submicroscopic balanced chromosomal translocation.

Drug combinations in the treatment of gastric adenocarcinoma: a randomized Southwest Oncology Group study.

The FAM combination with the simultaneous administration of 5-fluorouracil, doxorubicin, and mitomycin C is considered standard chemotherapy for gastric adenocarcinoma. This study was initiated to determine whether a kinetically designed sequential administration of these three drugs would be superior and whether the presence or absence of easily measurable tumor would imply differences in survival. To do so, the Southwest Oncology Group tested two schedules in a randomized study of 239 patients. Independent judgments of response were made by two authors with the same results. Equivalent response rates (23% of all eligible sequential and 30% simultaneous) and median survival durations (22 and 23 weeks, respectively) were seen. Patients with and without readily measurable tumors each lived a median of 22 weeks. Higher degrees of hematologic toxicity were associated with prolonged survival (median 27 weeks versus 20 weeks, p = 0.04). Patients treated by community oncologists were described as having higher response rates than those treated in major medical centers (64% versus 31%, p = 0.03). The meaning of this is questionable in that there were no statistical differences in survival or toxicity. Those with prior exposure to 5-fluorouracil had only a tendency, without statistical significance, for a slightly inferior response and survival.

[Presinusoidal portal hypertension in post-hepatitis cirrhosis].

Two cases of very probable post-hepatitis cirrhosis are presented. Both were complicated by presinusoidal portal hypertension (P. H. T.), the peroperative portal pressures measured directly being much higher than the wedged hepatic venous pressures. Although post-sinusoidal P. H. T. is the usual complication of most types of cirrhosis, these two cases support recent studies reporting the possibility of pre-sinusoidal P. H. T. in post-hepatitis cirrhosis. The wedged hepatic venous pressure is not a reliable indicator of portal pressure in these cases. The presence of presinusoidal P. H. T. does not exclude the diagnosis of cirrhosis but makes that of alcoholic cirrhosis very unlikely.

[Communication in "functional" and "dysfunctional" families with adolescent children. I. Verbal communication].

This research studies family communications during the critical period of change provoked by the puberty of one of the children. Two groups of families are compared: one group of 15 "functional" families (no psychological consultation has been requested) and one group of 15 "dysfunctional" families (a psychological consultation has been requested for one of the adolescents). The micro-analysis of the verbal communications reveals a few significant differences between the two groups of families. The results point to structural differences between the family systems.
