A case of drug eruption induced by hydroxyzine pamoate]

A 62-year-old woman with rheumatoid arthritis, Basedow's disease and arrhythmia has been treated with antirheumatic, antiarrhythmic drugs and so on. She developed pruritic diffuse erythema with papules on the trunk and extremities 2 days after taking hydroxyzine pamoate for asteatotic eczema. Laboratory data showed increased levels of eosinophils. Histopathological examination revealed a infiltrate of inflammatory cells in the upper dermis. Patch tests with hydroxyzine pamoate and hydroxyzine hydrochloride were positive. From these findings, we diagnosed this case as drug eruption due to hydroxyzine. Her eruption subsided after she discontinued hydroxyzine pamoate and other drugs which were started within 5 days before the onset of the eruption and was treated with systemic steroid, systemic antiallergic drug and topical steroid.     

Correlation between scalp-recorded electroencephalographic and electrocorticographic activities during ictal period.

OBJECTIVE: To investigate the correlation between scalp-recorded electroencephalographic (EEG) and electrocorticographic (ECoG) activities during ictal periods. METHODS: Simultaneous EEG and ECoG recordings with chronic subdural electrodes were performed in eight patients with partial epilepsy. RESULTS: In two cases where the ictal ECoG discharges originated in deep brain structures such as the hippocampus and interhemispheric surface of the frontal lobe, ictal discharges could not be detected on EEG until they expanded to the cortex of convexity. In four cases, the ictal onset zones were located in the lateral convexity. When synchronous or near synchronous ictal ECoG discharges with amplitudes of 200-2000muV were recorded on more than 8-15cm(2) of cortex, corresponding discharges were recorded on EEG in these four cases. However, in a case of frontal lobe epilepsy, asynchronous ictal ECoG discharges were recorded on 10 electrodes of convexity but no ictal EEG activity was recorded. Furthermore, in two frontal lobe epilepsy cases, ictal EEG discharges did not always reflect the ictal ECoG spike, but occasionally reflected slow background ECoG activity around the ictal discharges. CONCLUSIONS: Multiple factors such as the width of the cortical area involved, amplitude of ictal discharges and degree of synchronization of electrical potentials play important roles in the appearance of ictal EEG recordings, and the relationship between ictal EEG and ECoG is not straightforward.     

Prophylactic effect of UFT on the recurrence of bladder cancer

To evaluate the effect of UFT, a mixture of ftorafur and uracil in a ratio of 1:4, in preventing postoperative recurrence of bladder cancer, we performed a randomized controlled study with a non-medication group as control. UFT was given orally 400 mg a day for 6 months. Of 111 patients, 56 were given UFT and 55 were followed up without any medication. The non-recurrence rate in the group treated with UFT was 62.8% after 1 year and 36.3% after 2 years of follow up, and that of the control group was 45.7% and 39.5%, respectively. The rate of non-recurrence in the UFT group was significantly higher (p less than 0.05) than that of the control group during the period of follow up for 2 years. The incidence of side effects was 6.8% in UFT patients. These results indicate the clinical usefulness of prophylactic administration of UFT for bladder cancer patients.     

Successful Treatment of Adult T-cell Leukemia/Lymphoma with MACOP-B,M-FEPA and VEPP-B Combination Chemotherapy

A 45-year-old man was referred to our department in March of 1989. Physical examination showed erythroderma, palmo-plantar hyperkeratosis, generalized lymphadenopathy, hepatosplenomegaly, and leukemic manifestation. The lymphocyte count in the peripheral blood before treatment was 1.7 × 10⁴ cells/mm³. Atypical lymphocytes such as flower cells and lobulated cells were seen in the peripheral blood. A sample excised from a lymph node showed immunoblastic, pleomorphic T cells by a modified classification scheme of the Working Formulation. A high level of serum LDH was detected (2.1 times the upper normal limit). Anti HTLV-1 antibody was also detected in the serum. The atypical lymphocytes were positive for CD3, CD4, CD5, CD7 and HLA-DR, and negative for CD8. Thus, the clinical, pathologic and immunologic features were those of typical acute-type ATL. The patient was treated with VEPA-M for three months starting in March of 1989. Because of poor response, the patient was then treated with MACOP-B, M-FEPA, and VEPP-B for about one year from June of 1989 and has been free of disease up to the time of writing, March of 1993.     

Prevention of Acute Lung Allograft Rejection in Rat by CTLA4Ig

CTLA4 immunoglobulin (CTLA4Ig), which binds with a high affinity to B7-1 and B7-2, interrupts T-cell activation by inhibiting costimulatory signal. CTLA4Ig has been used in hopes of achieving antigen-specific tolerance induction in several solid organ transplants. In lung allograft rejection, however, its use has been controversial in terms of its effect on prevention of rejection. In the present study, the effect of murine CTLA4Ig on rat-lung allograft rejection was investigated. Rat left-lung transplantation was performed in an RT1 incompatible donor (Brown Norway; BN)-recipient (F344) combination. All allografts (n = 12) without any treatment were rejected within 7 days after transplantation. A single injection of murine form CTLA41g at a dose of 100 microg intraperitoneally (ip) or intravenously (iv) on day 1 post-transplantation achieved long-term graft survival (>90days) in 2/5 (40%) and 3/8 (38%), respectively. Moreover, 6/7 (86%) allografts in rats that received iv injection of 500 microg CTLA4Ig survived more than 90days. Allograft survival in the CTLA4Ig 500 microg iv recipient group was significantly longer than that in the no-treatment control or control immunoglobulin group (p <0.01). Four out of seven recipients bearing functional allografts for more than 90 days with the CTLA4Ig treatment accepted donor-specific skin grafts, whereas all third-party skin grafts (n=3) were rejected. Prevention of rat-lung allograft rejection could be achieved by intravenous administration of CTLA4Ig, resulting in long-term allograft survival with acceptance of donor-specific skin grafts.     

Study on the mass-screening of after-meal serum triglyceride concentration]

The serum triglyceride concentration (TG) tested in health checks after meals cannot properly sort out hypertriglyceridemia with reference to the upper normal limit of fasting TG (150 mg/dl) set by the Japan Arteriosclerosis Society, because TG goes up considerably after a meal. In our survey of a large number of health check examinees (free of abnormal biochemical data other than TG and diseases under medical treatment), the mean (M) of fasting TG + 2 standard deviations (SD) was close to 150 mg/dl. When the screening level was set at M + 2SD for each time span after a meal, the ratio of the screened was distributed between 19.9 and 21.8%, which was close to 23.5%, the ratio of the screened on fasting. Accordingly, the nearest round number ending with zero for the first digit is suggested to be of practical use for the screening level of after-meal TG. The average TG in females was definitely lower than that of males, though proportionately increasing with age. The ratio of the screened among females aged between 20 and 49 was 5.3% on fasting and 3.2-5.8% for after-meal time spans, and that of the screened aged in their fifties was 11.3% and 8.2-12.9% respectively.     

Effects of sex hormones on human PMN migration

It is believed that gingivitis at puberty is exaggerated by alterations of the hormonal balance. We have suggested that estradiol promotes the gingivitis at puberty while progesterone reduces it (J. Hiroshima Univ. Dent. Soc. 19: 1987). But the mechanisms of these hormones which influence gingival inflammation are not known yet. Therefore, we hypothesized that one of the possible mechanisms of sex hormones on gingival inflammation is through their action on polymorphonuclear leucocytes (PMNs) function because PMNs play an important role in periodontal disease. The purpose of this study was to investigate the effect of sex hormones on PMNs function, especially their migration in vitro. PMNs and plasma were obtained from heparinized peripheral blood of 23 healthy adults. PMNs were preincubated at 37 degrees C for 15 minutes with progesterone or 17 beta-estradiol at designated concentrations. After preincubation, PMNs migration was measured using 48-well chemotaxis micro-chamber with N-formyl-methionyl-leucyl-phenylalanine (FMLP) as chemoattractant. The levels of estradiol and progesterone in the plasma were determined using Direct Radioimmunoassay Kits and the correlation between sex hormone levels and PMNs migration was investigated. PMNs migration to 10(-6) M FMLP was enhanced significantly by progesterone at the concentrations of 200 ng/ml while it was reduced by estradiol at 0.4 ng/ml and 2.0 ng/ml. Random migration of PMNs was enhanced significantly by progesterone at 20 ng/ml while it was reduced by estradiol at 0.4 ng/ml. Significant positive correlation was found between progesterone level in plasma and the PMNs migration in vitro. Estradiol level in plasma did not have any correlation with the PMNs migration in vitro.(ABSTRACT TRUNCATED AT 250 WORDS)     

Fibroepithelial polyp of the verumontanum

A case of fibroepithelial polyp of the verumontanum in a 20-year-old male is presented. The endoscopic examination revealed polypoid lesion protruding from the verumontanum, and transurethral resection of the tumour was performed. The histopathological diagnosis was fibroepithelial polyp, containing no prostatic glandular structures. As the nomenclature of the lesions is widely varying, we tried to classify polypoid or papillary lesions of the prostatic urethra by a literature review.     

Addition of Transdermal or Inhaled Long-Acting β 2-Agonists in Adult Asthmatic Patients Treated with Inhaled Corticosteroids: Switchover Study from Tulobuterol Patch to Salmeterol Dry Powder Inhaler

Sixty-four patients with persistent asthma receiving 200 to 800 μ g of fluticasone propionate daily were enrolled in this switchover study. The patients applied a tulobuterol patch 2 mg every 24 hours for 4 weeks followed by inhalation of salmeterol 100 μ g bid for 4 weeks. The mean values for morning and evening peak expiratory flow improved significantly compared with baseline during the 4 weeks of tulobuterol patch treatment. Further improvement was seen on switching to salmeterol treatment, which was significant even in the first week, and continued until the final week of the study. Use of salmeterol alone resulted in a significant increase in the percentage of forced expiratory volume in 1 second %FEV1 from baseline, with 51% of patients feeling that the treatment was effective (vs. 37% on tulobuterol). These data suggest that salmeterol can achieve better control in asthmatic patients after switching from using tulobuterol patches.
