BACKGROUND: The present study was conducted to investigate how patients with clinically localized prostate cancer were treated in the Hokuriku District, Japan. METHODS: Medical records of 536 patients with stage B prostate cancer were retrospectively reviewed. The patients were diagnosed and treated at four university hospitals and 32 collaborating hospitals in the Hokuriku District. RESULTS: Because their medical records were incomplete and/or they not available for follow up, 79 cases were excluded from this study. Conservative treatment with hormone therapy was used for 248 cases. Radical prostatectomy was performed in 199 cases, only 27 of whom underwent surgical monotherapy. There was no significant difference in disease-specific survival rates between the hormone (69.0%) and surgery group (83.2%) after 110 months. Results of the analysis of disease-specific survival rates according to histologic grade showed that patients with poorly differentiated cancers treated with hormone therapy were the only subset with significant differences when compared against the other patients. CONCLUSION: The value of prostatectomy alone or added was marginal in terms of survival. Only patients with poorly differentiated cancer might benefit from prostatectomy. 相似文献

In São Paulo City, Brazil, 121 patients with moderatelysevere envenoming by Bothrops snakes (principally B. jararaca)were randomized for treatment with Brazilian polyspecific Bothropsantivenoms: Instituto Butantan (39 patients), Instituto VitalBrazil (41), Fundação Ezequiel Dias (FUNED) (41).The initial dose was four ampoules (40 ml) in 89 patients withless severe envenoming and eight ampoules (80 ml) in 32 patientswith more severe envenoming. A second dose of four ampouleswas required in 20 patients. Patients receiving the three antivenoms were comparable in allrespects before treatment There were no deaths. The majorityshowed rapid clinical improvement, resolution of local envenoming,cessation of bleeding and restoration of blood coagulability.No differences in the efficacy of the three antivenoms wererevealed by clinical or laboratory observations, including measuresof haematological, haemostatic and biochemical ab normalities.Twelve patients developed abscesses (Butantan 1, Vital Brazil6, FUNED 5) and seven developed local necrosis (3,1,3). Of 88patients followed up 2030 days after the bite 33 (37.5%)still had symptoms or signs of local envenoming, especiallyswelling. Early (anaphylactic) reactions were unexpectedly frequent afterall three antivenoms but were significantly more frequent withButantan (87%) than with Vital Brazil (37%) or FUNED (56%) antivenoms(p < 0.001). A possible explanation was the higher totalprotein content and percentage immunoglobulin of Butantan antivenom. The doses of antivenom recommended in Brazil and used in thisstudy may be unnecessarily high, resulting in an unacceptablyhigh incidence of reactions. Results of the study should prompta critical re-evaluation of antivenom production techniquesand dosage recommendations in Brazil. 相似文献

Signet-ring cell carcinoma of the prostate effectively treated with maximal androgen blockade 总被引:3,自引:0,他引:3
KEIGO AKAGASHI HITOSHI TANDA SHUJI KATO SHIGEKI OHNISHI HISAO NAKAJIMA AKIHITO NANBU TOSHIKAZU NITTA MIKIO KOROKU 《International journal of urology》2003,10(8):456-458
Primary signet-ring cell carcinoma (SRCC) of the prostate is very rare and has a poor prognosis, even when treated with aggressive therapy. We report herein a case of a 72-year-old man with prostatic SRCC. The patient had a tumor that extended directly to the rectum. Maximal androgen blockade was started and 20 months later, the patient was alive without evidence of recurrence. The present case of prostatic SRCC responded well to medical therapy, however, tumors can recur after a long period of time. Therefore, adjuvant therapy is recommended. 相似文献

ABSTRACT. We studied the relationship between serum calcium and urinary calcium excretion in association with the parathyroid function in 28 neonates at birth and at five days of age. At birth, the urine calcium was low in spite of high cord serum calcium and a low parathyroid hormone level. On the fifth day of birth, urinary calcium excretion increased despite the reduction in serum calcium and an increase in the parathyroid hormone. These results suggest that the large increase in renal blood flow and the consequent increase in calcium load on the immature renal tubule occurring after birth may be the main cause for the change in this serum calcium-urinary calcium relationship. This finding can in part explain the temporary hypocalcemia during this period. 相似文献

This is the report on a prospective, single blind, comparative study of a component acellular pertussis vaccine produced by a combination of detoxified, column purified pertussis toxin (PT) and filamentous hemagglutinin (FHA) combined with diphtheria and tetanus toxoids (DTcaP) and the traditional acellular pertussis vaccine produced with essentially the same method as described by Sato with DT (DTaP) of the same manufacturer. A total of 616 infants and children received DTcaP and a total of 289 received DTaP. In all age groups for both vaccines values of serum antibodies to PT and FHA after two doses of the vaccines were comparable to those of convalescent sera. Incidences of systemic and local reactions were, in general, not greatly different between DTcaP and DTaP recipients. In Japan the use of traditional acellular vaccines replaced whole cell vaccines in 1981. Protective antigens of Bordetella pertussis have now been specified and thus component vaccines have become theoretically possible. This is the first component vaccine which has been developed in Japan. Several other component vaccines are now under investigation in the world. 相似文献

The present study examined chronotropic dysfunction and the role of vagotony in congenital long QT syndrome, sinus node function and the effects of parasympathetic blockade. Six patients with congenital long QT syndrome were studied. The four males and two females, aged 1–15 years, had episodes of syncope and malignant ventricular arrhythmias. Congenital long QT syndrome was defined as a corrected QT interval greater than 0.45 s, T wave alternans and the age at diagnosis. The sinus heart rate measured from a 24 h electrocardiograph was abnormally low (< 50 min) in three patients (1, 4 and 5 years old) and did not increase sufficiently with the administration of atropine in five of the six patients with congenital long QT syndrome. From intracardiac electrophysiological studies, the corrected sinus node recovery time was prolonged in three patients and the total sinoatrial conduction time was prolonged in two patients. In most patients who had an abnormally long sinoatrial conduction time and corrected sinus node recovery time, these values returned to normal following atropine administration. In one patient, the corrected sinus node recovery time was prolonged paradoxically by atropine. Sinus node dysfunction in congenital long QT syndrome was affected by vagotony associated with a right sympathetic nerve system abnormality. 相似文献

This study attempted to determine whether patients with major depression and panic disorder could be differentiated by personality features, measured by the Munich Personality Test (MPT). One of the six MPT personality dimensions, `rigidity', was developed in relation to the `melancholic type of personality', which may be a specific personality feature of depressive subjects. We therefore hypothesized that the MPT might be sensitive to possible personality differences between patients with major depression and panic disorder. Sixty-six patients with major depression and 27 patients with panic disorder, taken from consecutive intakes at an outpatient unit, were compared in terms of six personality dimensions of the MPT. The results demonstrated that rigidity could significantly differentiate the two patient groups, even after the possible confounding effects on the personality assessments were statistically partialled out. The MPT was suggested to be powerful for describing distinctive personality features of depressive subjects from anxiety subjects. 相似文献

Functional CD86 (B7-2/B70) is predominantly expressed on Langerhans cells in atopic dermatitis 总被引:3,自引:0,他引:3

Recently, we reported the functional expression of CD86 on cultured human Langerhans cells derived from normal epidermis. In the present study, we investigated the expression and function of co-stimulatory molecules in the pathogenesis of atopic dermatitis. In immunohistochemical analysis, CD80 and/or CD86 were detected on dendritic-shaped cells not only in the epidermis but also in the dermis in the inflammatory lesions of atopic dermatitis (n = 12). CD80 was expressed in only five cases (42%), while CD86 was expressed in all cases (100%). These molecules were not detected in normal control subjects (n = 8). In non-lesional skin of atopic dermatitis (n = 4). CD86 but not CD80 was detected in one case. CD86 was preferentially induced on dendritic-shaped cells in positive patch test sites to Dermatophagoides pteronyssinus or house dust allergen in atopic dermatitis (n = 4). The CD80- or CD86-positive cells were confirmed as Langerhans cells by double immunostaining using anti-CD1a monoclonal antibody. Neither CD86 over that CD80 was detected n keratinocytes. Similar results of the stronger expression of CD86 over that of CD80 were obtained from psoriasis vulgaris (n = 11) and from contact dermatitis (n=7), although CD86 was expressed only in 57% of the contact dermatitis cases. The percentage of Langerhans cells positive for CD86 was higher than for CD80, i.e. 48% compared with 9%, respectively, in the epidermis of lesional skin of atopic dermatitis (n=8). The expression rate of these molecules on Langerhans cells increased in the dermis. To investigate the function of co-stimulatory molecules on Langerhans cells in atopic dermatitis, we conducted an inhibition test with antibodies. Anti-CD86 monoclonal antibody almost completely nhibited T-cell proliferation stimulated with crude extract of D. pteronyssinus in the presence of epidermal cells as antigen-presenting cells, whereas anti-CD80 monoclonal antibody produced less of an inhibitory effect. These data indicate that CD86 expressed on Langerhans cells may play an important part in the pathogenesis of atopic dermatitis.for Investigative Dermatology. Washington, DC (1–5 May 1996). 相似文献
