Dynamic high-spatial-resolution MR imaging of invasive ductal carcinoma: influence of histological scirrhous component on MR descriptors.

PURPOSE: The purpose of this study was to assess the relationship between the amount of scirrhous component in invasive ductal carcinoma and its MR characteristics. MATERIALS AND METHODS: We retrospectively reviewed 71 consecutive patients with invasive ductal carcinoma smaller than 25 mm (average, 16.6 mm) in diameter. The scirrhous component was defined as invasive foci in small clusters of cancer cells showing desmoplasia. Invasive ductal carcinoma was subclassified into 3 groups in accordance with the amount of the scirrhous component (scirrhous component degree; SCD): SCD I (scirrhous component less than 20%), SCD II (intermediate), and SCD III (more than 80%). Dynamic magnetic resonance (MR) imaging was performed using volumetric interpolated sequence. Prior to dynamic study, T2*-weighted first-pass perfusion images were obtained before, during, and after bolus injection of 0.1 mmol Gd-DTPA/kg. RESULTS: Twenty-eight lesions were classified as SCD I, 14 as SCD II, and 29 as SCD III. Mass margin and signal intensity loss in the perfusion study were significantly different among the 3 SCD groups (P<0.001). The kinetic patterns were significantly different among the 3 SCD groups (P=0.04), and between SCD I/II and SCD III (P=0.03). The presence of enhancing internal septations was significantly different between SCD I/II and SCD III carcinomas (P=0.05). Central enhancement was only observed in SCD I carcinoma (4%; 3/71). CONCLUSION: The histological predominance of the scirrhous component in invasive ductal carcinoma may be one explanation for the differences in morphologic and kinetic patterns on MR imaging.     

Investigation of recent problems in an acute care psychiatric ward considering the number psychiatrists working in the ward]

In July 2001, psychiatric wards for acute treatments (PWAT) were investigated in Japan using a questionnaire to clarify current and recent problems in 79 PWAT. The questionnaires were sent to wards, patients and psychiatrists and were returned by 72.2% overall. The number of admissions per ward was calculated as 21 patients per one month, and comprised half of all admissions to the hospital. 50% were schizophrenia, 17% were affective disordes and 16% involved drug abuse. Seventeen patients were discharged from PWAT per one month, and comprised 43% of all patients discharged from the hospital. These results indicate that both 21 patients admitted and 17 patients discharged per month and needs to maintain the essential standard for PWAT and the standard should be come more flexible as admission from the other unit of ward than PWAT. As rate of re-admission within 3 months after discharge was around 10% of the total number of patients in the ward, 3 months was considered suitable length of acute treatment in the field of psychiatry in Japan. There was one psychiatrist working in PWAT, and specialized psychiatrists had 17.4 patients, the most number of patients among types of psychiatrist. Simulations of one psychiatrist to 16 and to 32 patients in PWAT were performed to determine how many psychiatrists were needed for a ward. When the ratio was 32 patients to 1 psychiatrist, it was necessary to increase the number of psychiatrists to a ward by 1, and in the case of 16 patients, 1-3 psychiatrists were needed. These indicate the standard number of psychiatrists for PWAT should be at most one psychiatrist for the ward or all of the psychiatrists working in PWAT should be allowed to work simultaneously in other wards. Preparing wards to treat acute phase psychiatric patients is a very important role of each psychiatric hospital, the standard for PWAT should include not only a high level of medical staff, but also preparing easy criteria for each hospital.     

Effects of Topically Applied Spironolactone on Androgen Stimulated Sebaceous Glands in the Hamster Pinna

The effects of spironolactone (5% SYC-201G, a preparation developed for clinical use in acne vulgaris by Searle Yakuhin K.K.), which is known to have antiandrogenic effects by competitively inhibiting dihydrotestosterone at androgen receptor sites, was topically applied to the androgen stimulated sebaceous glands of adult female golden hamsters. Androgen stimulation, induced by intramuscular injection of testosterone propionate (TP) every other day over a two week period, resulted in a 2.5 to 2.7 time increase in the size of the sebaceous glands of the hamster pinna. Once-daily treatment with 5% SYC-201G or matching placebo was applied to androgen-stimulated hamsters on one pinna only during the same period as TP injection. Comparison between the treated and untreated sides revealed a significant suppression in the sebaceous gland size (p<0.05) by 5% SYC-201G; no such effect was observed with placebo. The difference in the suppression rate of the sebaceous gland size between 5% SYC-201G (23%) and matching placebo (–4.7%) was significant (p<0.01).     

Active production of anti-human T-lymphotropic virus type I (HTLV-I) IgM antibody in HTLV-I-associated myelopathy

We investigated the presence of anti-human T-lymphotropic virus type I (HTLV-I) IgM in sera and cerebrospinal fluid from patients with HTLV-I-associated myelopathy (HAM) by Western blot analysis. Analyses of 36 serum samples revealed that most patients (31/36; 86.1%) had anti-HTLV-I IgM, whereas only four of 23 (17.4%) HTLV-I carriers had it. In studies of cerebrospinal fluid, anti-HTLV-I IgM was detected in 24 of 36 (66.7%) HAM patients, whereas none was detected in nine HTLV-I carriers. The differences were statistically significant (p less than 0.01). These results suggest that persistent active replication of HTLV-I occurs in the central nervous system as well as in the peripheral blood of HAM patients, and may contribute to the development of HAM.     

Four primary malignant tumors, including malignant melanoma and malignant lymphoma, in the same adult patient

We report an 80-year-old Japanese male with four primary malignant tumors: malignant melanoma, prostatic cancer, malignant lymphoma, and renal cell carcinoma, which occurred in that respective order. The combination of malignant melanoma and malignant lymphoma is rare. The patient was treated with BCG after an operation for malignant melanoma. He was also treated with cobalt 60 irradiation after an operation for prostatic cancer. We also discuss other reports of multiple malignant tumors and suggest some possible causes of this patient's primary malignant tumors.     

Effect of anti-PcrV antibody in a murine chronic airway Pseudomonas aeruginosa infection model.

Pseudomonas aeruginosa is one of the most important pathogens in patients with chronic airway conditions, such as cystic fibrosis and diffuse panbronchiolitis. Type III secretion system-mediated virulence factors contribute to the lung damage in chronic P. aeruginosa infection. The effects of the anti-PcrV immunoglobulin (Ig)G, which blocks the type III secretion system, were evaluated in a mouse model of chronic P. aeruginosa infection. On bacteriological examination, anti-PcrV IgG showed no bactericidal effects. On bronchoalveolar lavage fluid (BALF) analysis, total cell number and neutrophil ratios in the anti-PcrV IgG-treated groups were lower than those in the control group. In addition, macrophage inflammatory protein-2, tumour necrosis factor-alpha, and interleukin-beta concentrations in BALF were lower in the anti-PcrV IgG-treated groups when compared with controls. Plasma anti-PcrV IgG titre was elevated after administration of anti-PcrV IgG. Although plasma titre decreased gradually, a significant concentration was maintained during the experimental period. These data suggest that anti-PcrV immunoglobulin G reduces the inflammatory reaction caused by chronic Pseudomonas aeruginosa respiratory infection and may be useful in treating respiratory diseases.     

A female case with Down syndrome and non-neurogenic neurogenic bladder

Although the prevalence of a learned voiding dysfunction and non-neurogenic neurogenic bladder (NNB), which is one type of dysfunctional elimination syndrome, is considered to be relatively rare, the association of NNB with Down syndrome (DS) has been elucidated in male patients. We herein describe the occurrence of NNB in an adult female with DS. The diagnosis was confirmed after completely ruling out any neurological or anatomical anomalies that could be related to a lower urinary tract dysfunction. She had renal dysfunction and multiple obstructive uropathies for which clean intermittent catheterization was successfully introduced.     

A successful surgical case of aortic arch aneurysm associated with aortic regurgitation

A 57-year-old male patient with aortic regurgitation and aneurysm of the ascending aorta and the aortic arch underwent aortic valve replacement and graft replacement from the ascending aorta to the aortic arch. The operation was done using cardio-pulmonary bypass and selective cerebral perfusion with deep hypothermia. Postoperative DSA revealed no dilatation of the sinus Valsalva and a good configuration of the anastomosis. It seems that selective cerebral perfusion with deep hypothermia is a safe method to prevent cerebral damage in a case of arch aneurysm.
