ABSTRACT

Glucocorticoids (GCs) are widely used for the treatment of various diseases, particularly in dermatology. However, there have been few reports about the outcome of treatment for GC-induced osteoporosis in patients with dermatological conditions receiving oral GCs. The present study was undertaken to prospectively evaluate the usefulness of etidronate for preventing steroid-induced osteoporosis in patients on prolonged GC therapy as routine clinical management. In total, 110 patients receiving oral GC therapy were enrolled into the study. Of these, 87 patients were evaluated (44 patients with collagen diseases, 13 patients with autoimmune bullous dermatoses, 19 patients with chronic eczema/dermatitis, 2 patients with toxicoderma/drug eruption and 9 others). Urinary deoxypyridinoline (DPD) was evaluated as a marker of bone resorption, and serum bone-specific alkaline phosphatase (BAP) as a marker of bone formation. Significant increases in urinary DPD were seen in the control group after oral GC therapy had been continued for ≥ 1 year. Treatment with etidronate suppressed this increase. When the patients were stratified according to gender, this improvement was more obvious in women. No significant difference in serum BAP level was found between the two groups. These results suggest that bisphosphonates may be useful for preventing steroid-induced osteoporosis in dermatology patients (particularly women) receiving oral GC therapy.

ABSTRACT

MRL/Mp-lpr/lpr (MRL/lpr) mice are characterized by the disorder of apoptosis due to defects in Fas antigens and autoimmune symptoms including spontaneous lupus erythematosus (LE)-like skin lesions. MRL/Mp- + / + (MRL/n) mice do not carry the defect of lpr mutation nor do they exhibit skin disorders during the first six months of life. Retinoids are known to inhibit the proliferation of skin fibroblasts, collagen synthesis, modulate immune responses, and apoptosis by Fas ligand upregulation in skin fibroblasts. We examined changes in dermal thickness and appearance of skin disorders in five months old MRL/lpr mice by oral treatment with etretinate, a retinoic acid derivative. Etretinate treated MRL/lpr mice did not have skin lesions or dermatopathological characteristics including an increase in cells infiltrating the dermis. The mean dermal thickness of MRL/lpr and MRL/n mice treated with etretinate decreased significantly and apoptotic cells density in the dermis of MRL/lpr mice with etretinate was significantly higher compared with the control group (P < 0.05) although MRL/lpr mice have a defect within the Fas antigen. We assumed that etretinate reduced dermal thickness, and suppressed the appearance of skin lesions by inducting apoptosis and perhaps regulation of cytokine expression.

ABSTRACT

The anticancer agent 5-fluorouracil (FU) frequently induces cutaneous lupus erythematosus (LE) lesions on sun exposed sites. Based on this observation, we have tried to establish a cutaneous LE model of C57BL/6 J (B6) mice, B6 T cell receptor (TCR)-alpha(-/-) mice and B6 TCR-delta(-/-) mice treated with FU and/or ultraviolet B light (UVBL) in order to clarify the role of T cells and the cytokine profile of cutaneous lupus lesions. Cutaneous LE-like skin lesions could be induced in TCR-alpha(-/-) mice with low FU (0.2 mg) plus UVBL, and in B6 mice treated with a high dose of FU (2.0 mg) plus UVBL. In contrast, low FU plus UVBL induced such skin lesions in TCR-delta(-/-) mice at a very low incidence. Specifically, the skin lesions of TCR-alpha(-/-) mice with low FU plus UVBL appeared more rapidly and were more severe than lesions in B6 mice. The former had the common characteristic features of human chronic cutaneous LE such as typical histology, positive IgG at the dermoepidermal junction, low antinuclear antibody and low mortality. Furthermore, a Th1 response was induced in the development of drug-induced cutaneous LE. FU and UVBL-induced cutaneous LE-like eruption is an excellent model for better understanding the pathomechanisms of skin lesion development in LE.

ABSTRACT

School refusal has become a relatively common problem of increasing magnitude in Japan. Although clarification of the relationship between 'school refusal' and 'depression with school inattendance' is crucial in light of the difference in treatment modalities involved, it is not clear whether the two are to be regarded along the same tangent or as disparate entities. For clarification, a comparison was made between clinical diagnosis, Children's Depression Inventory (CDI) scores, and scores for the three subordinate scales of the CDI in 34 cases of school refusal, 10 cases of depression with school inattendance, and normal students. Significant difference in CDI score was noted between the three groups: highest among depression cases, followed by school refusers, and lowest in normal students. A larger proportion of school refusers expressed somatic complaints together with low CDI scores. The typical case of school refusal appears to exhibit somatic complaints in the foreground rather than depression, both clinical characteristics and CDI scores indicate school refusal and depression to be separate entities. Although many approaches are being taken in the treatment of school refusal, the results appear to justify primacy of the psychotherapeutic approach with the possible adjuvant use of pharmacological agents, for the phenomenon as it presents in Japan.

ABSTRACT

A 59-year-old woman was admitted to our hospital because of massive bleeding from a right breast tumor. The breast tumor had existed for ten years occupied the entire right breast (23 x 20 cm), its central part forming an ulcer 17 x 15 cm in size. Radiotherapy to the right breast and medication with tamoxifen were started, after which five courses of CMF chemotherapy were given. The tumor decreased to 16 x 14 cm, and hyperthermia to the right breast was performed for a total of 87 sessions from January 1999. The irregular protruding portion of the ulcer caused the necrosis, and was sloughed off about one month after hyperthermia. No viable tumor cells were observed in a biopsy taken at 5 months after the start of treatment (40 sessions). A total of 87 hyperthermia sessions were performed, and the ulcer disappeared. For 15 months after the end of hyperthermia, the patient showed a continuous CR. Hyperthermia in combination with radiotherapy or chemotherapy for breast cancer may produce a remarkable effect as in the present case, and may become one choice for medical treatment of locally advanced or recurrent breast cancer.

ABSTRACT

BACKGROUND: It is difficult to control non-resectable locally advanced primary and recurrent breast cancer by conventional modalities. Recently, hyperthermia (HT) has been recognized as an effective adjuvant to radiotherapy (RT) and chemotherapy (CT) in treatment of various malignancies, including breast cancer. PATIENT AND METHODS: The patient was a 58-year-old female Japanese, with breast cancer, T4N2M0, stage IIIb (papillo-tubular carcinoma). Previous treatment included RT and neoadjuvant CT Local HT was performed with a total number of 87 sessions given over 12 months. The mean time of each session was 40 minutes. Elevation of temperature to a tumoricidal level of 43 degrees C was confirmed. The patient received cyclophosphamide (50 mg p.o./day) and tamoxifen (20 mg p.o./day) during the whole period of HT. Due to the decreased amount of WBC, further CT was not possible, except for one course of CMF performed 3 months after the start of HT. RESULTS: The patient had a decrease in the intensity of pain even after the first 3 sessions. In one month, movement in the right shoulder became possible in an anterio-posterior direction. By 5 months, the healing of ulceration became evident. At present, the patient is in continuous CR for 15 months after HT. The movement in the shoulder joint is markedly improved in all directions. In addition, HT did not cause any notable complications. CONCLUSION: Long-term HT may be useful in the management of locally advanced breast cancer and these results should encourage further clinical study.

ABSTRACT

Purpose: Recently, intraocular lidocaine anesthesia has been used in cataract surgery. We studied the toxicity of intraocular unpreserved lidocaine for corneal endothelial cell and retina using Japanese white rabbits.Methods: The rabbits were divided into two groups. One group was injected intracamerally and the other was injected intravitreally with 0.2 ml of unpreserved lidocaine of 0%, 0.02%, 0.2%, or 2% concentration. The number of corneal endothelial cells was measured 1 week after the injection. After measurements, the rabbit corneas were studied histologically. The retina was examined by electroretinogram prior to initial injection through 1 week after the injection.Results: There was no significant change in number of corneal endothelial cells after injection of 0.2% lidocaine. However, histological abnormality was seen in corneal endothelial cells after 2% lidocaine injection. There was also significant change in electroretinogram with 2% lidocaine injection. No histological abnormality was seen in the retina 1 week after the injection.Conclusion: The rabbit cornea and retina manifested no serious changes after the injection of lidocaine at less than 0.2% concentration functionally and histologically.

The retina was examined by electroretinogram from before the injection through 1 week after the injection. RESULTS: There was no significant change in number of corneal endothelial cells after injection of 0.2% lidocaine. However, histological abnormality was seen in corneal endothelial cells after 2% lidocaine injection. There was also significant change in electroretinogram with 2% lidocaine injection.

ABSTRACT

OBJECTIVE: To investigate the relationship between preperitoneal fat thickness (PFT) determined by ultrasonography and the risk of coronary arterial disease, 130 non-obese patients with ischemic heart disease (77 men and 53 women) were examined. RESULTS: There was a positive correlation between PFT and coronary artery stenosis score (r = 0.212, P < 0.05). After dividing the patients by gender, the correlation was recognized only in men (r = 0.246, P< 0.05). Also, PFT was positively correlated to serum total cholesterol (r = 0.259, P < 0.01), triglyceride (r = 0.205, P < 0.05) and low density lipoprotein (LDL)-cholesterol (r = 0.205, P < 0.05), and negatively correlated to serum high density lipoprotein (HDL)-cholesterol (r = -0.261, P < 0.01). Again, these correlations were found only in men, not in women. CONCLUSION: PFT shows good correlations with coronary artery stenosis score and dyslipidemia, and may lead to the development of coronary artery disease in non-obese male subjects.

ABSTRACT

PURPOSE: To determine the type of herpes simplex virus in acute retinal necrosis syndrome associated with herpes simplex virus. METHODS: Herpes simplex virus type 1, herpes simplex virus type 2, varicella-zoster virus, Epstein-Barr virus, and cytomegalovirus were examined by polymerase chain reaction in intraocular specimens from 16 patients with acute retinal necrosis syndrome. Anti-herpes simplex virus type 1 and anti-herpes simplex virus type 2 type-specific antibodies in serum from the patients were detected by enzyme immunoassay. RESULTS: Of 16 patients with acute retinal necrosis syndrome, seven were polymerase chain reaction positive for herpes simplex virus type 2 and nine were positive for varicella-zoster virus. Anti-herpes simplex virus type 2 antibody was positive and anti-herpes simplex virus type 1 antibody was negative in the sera of the seven patients with herpes simplex virus type 2 DNA-positive acute retinal necrosis syndrome. In contrast, anti-herpes simplex virus type 2 antibody was absent in all nine varicella-zoster virus DNA-positive acute retinal necrosis syndrome patients. CONCLUSION: Herpes simplex virus type 2 has been demonstrated to be the major causative agent in acute retinal necrosis syndrome associated with herpes simplex virus by molecular biological and serological methods. Negative preexisting anti-herpes simplex virus type 1 antibody may play an important role in acute retinal necrosis syndrome associated with herpes simplex virus type 2.

ABSTRACT

A novel method of assessing the extent of oral bioavailability of arginine-vasopressin (AVP) from pharmacological data was presented. After intravascular administration (i.v. bolus or short-term infusion) of AVP to rats, the relationship between blood concentrations and its effect on both mean arterial pressure (hemodynamic effect) and urinary sodium concentration (anti-diuretic effect) was described on the basis of an integrated pharmacokinetic-pharmacodynamic (PK-PD) model. A direct model was used for the hemodynamic response, while an indirect response model, rather than a hypothetical link model was used for the anti-diuretic response. A sigmoid Emax model was applied to describe the drug-receptor interaction. Pharmacological responses after intravascular administration of AVP were reasonably described by the PK-PD model. However, PD parameters estimated by the PK-PD analysis suggested that apparent receptor affinity rather than efficacy in i.v. bolus study was significantly higher than that in the short-term infusion study. This fact indicated that PK-PD relationship was influenced by the intravascular input rate of AVP. We then investigated the relationship between plasma concentration and amount of AVP bound to the V2 receptors in the kidney. The result indicated that the amount of AVP bound to the receptors after i.v. bolus injection was always greater than that after short-term infusion. Since the PK-PD relationship after oral administration was almost identical with that after short-term infusion, the PK-PD model obtained in the short-term infusion study was used to assess the extent of oral bioavailability (EBAPp.o.). The EBAp.o. values, estimated from pharmacological effects (hemodynamic effect and anti-diuretic effect) after oral administration of 5 microg/kg of AVP were 0.68% to 0.93% and were almost identical with the actual EBAPp.o. value (0.81%). From these results, we concluded that oral bioavailability of AVP was reasonably predicted by the PK-PD model, provided that appropriate pharmacological effects and appropriate intravascular dosing rate as a reference formulation are available. The method may be an alternative to methods based on plasma concentrations, when drug concentration cannot be measured and when appropriate pharmacological data are available.

ABSTRACT

BACKGROUND: Simvastatin, a 3-hydroxy 3-methylglutaryl co-enzyme A (HMG-CoA) reductase inhibitor, is used widely for treatment of hypercholesterolemia. Simvastatin may be a suitable treatment for dyslipidemia in hemodialysis (HD) patients. However, investigation of the side-effects and safety of long-term administration of simvastatin to HD patients has been limited. In this study, we investigated the effects and safety of simvastatin and its effects on lipoprotein metabolism in hypercholesterolemic patients on HD. METHODS: Simvastatin was administered at a dosage of 5 mg/day for 24 weeks to 38 HD patients with high serum total cholesterol (TC) levels (200 mg/dl) or low high-density lipoprotein cholesterol (HDL-C) levels (35 mg/dl). Every four weeks, serum lipids, apolipoprotein, lipoprotein (a) [Lp(a)] and malondialdehyde (MDA) levels were measured. In addition, lipid levels were determined in each lipoprotein fraction separated by ultracentrifugation. RESULTS: After 24 weeks of simvastatin administration, TC significantly decreased by 25.7%, and low-density lipoprotein cholesterol (LDL-C) was significantly decreased by 33.6%. Triglyceride (TG) and HDL-C showed no significant changes. Apolipoprotein (apo) B significantly decreased by 24.5% and apo E by 30.0%. No significant changes were observed in the other apolipoproteins. MDA was also significantly decreased, whereas Lp(a) was not significantly altered. In the lipoprotein fractions, very LDL cholesterol (VLDL-C), intermediate-density lipoprotein cholesterol (IDL-C), LDL1 cholesterol (LDL1-C), and LDL2 cholesterol (LDL2-C) showed significant decreases. No particular side-effects were observed during the 12 months of simvastatin administration. CONCLUSIONS: These results suggest that simvastatin appears to be safe and effective in HD patients with hypercholesterolemia.

ABSTRACT

Twenty-five heterozygous familial hypercholesterolemic patients treated with LDL-apheresis and drugs and 11 patients treated with drugs underwent follow-up angiography 2.3 years later. One-hundred thirteen lesions were measured by quantitative angiography. Mean LDL-cholesterol levels during the trial were 140 +/- 34 mg/dl in the apheresis group and 170 +/- 58 mg/dl (P < 0.05) in the control group. The mean changes in minimal lumen diameter of lesions were +0.19 +/- 0.30 mm (improved) in the apheresis group (n = 76) and -0.44 +/- 0.40 mm (worsened) in the control group (n = 37) (P < 0.0001). When progression and regression were defined as a change in minimal lumen diameter of +/- 0.67 mm, in the apheresis group, two (8%) patients had progression, 19 (76%) stayed unchanged and four (16%) had regression, but in the control group seven (64%) patients had progression and four (36%) stayed unchanged. The frequency of regression or no change was significantly higher in the apheresis group than in the control group (P < 0.004). Intensive cholesterol lowering therapy with LDL-apheresis and lipid lowering drugs can achieve a substantial decrease in LDL-cholesterol levels to induce regression of coronary lesions in familial hypercholesterolemic patients with advanced coronary artery disease.

ABSTRACT

PURPOSE: To evaluate the effects of intracameral anesthesia on the corneal endothelium. SETTING: Department of Ophthalmology, Yokohama City University School of Medicine, Yokohama, Japan. METHODS: This study comprised 24 eyes of 12 white rabbits. One eye of 3 rabbits each was injected with preservative-free lidocaine at concentrations of 0.02, 0.2, or 2% and the fellow eye injected with balanced salt solution (BSS) as a control. The anesthetic agent was injected into the anterior chamber using a bimanual technique. Immediately after enucleation, the cornea was examined by scanning electron microscopy. RESULTS: Scanning electron microscopy revealed no abnormal findings in the eyes injected with lidocaine 0.02 or 0.2% when compared with eyes in the control group. Scanning electron microscopy of the eyes injected with lidocaine 2% showed irregular hexagonal endothelial cells and a significant loss of microvilli. CONCLUSION: Intracameral anesthesia with high concentrations of lidocaine risks corneal endothelial damage but at the low concentration usually used in cataract surgery did not appear to have an adverse effect.

ABSTRACT

The relationship between an infant's temperamental difficulty and the mother's child-rearing stress was investigated in a sample of 128 children. Children's temperament was assessed by the Revised Infant Temperament Questionnaire (RITQ) at 6-7 months, and by the Toddler Temperament Scale (TTS) at 18 months. The mothers' child-rearing stress was assessed by a self-report questionnaire. At the children's age of 18 months, mothers of difficult children reported higher child-rearing stress than mothers of easy children. Although difference in the level of child-rearing stress reflecting birth order was not evident at either 6-7 months or 18 months, the proportion of child-rearing stress which could be explained by the children's temperament was highest for mothers of first-borns when their children were 18 months old.

ABSTRACT

Levels of plasma soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 (sICAM-1), and von Willebrand factor (vWF) increase in patients with peripheral vascular or ischemic heart disease. These factors are related to the progression of atherosclerosis. Furthermore, these substances and thrombomodulin (TM) are indicators for assessing the degree of damage to the endothelium. To evaluate the effect of double filtration plasmapheresis (DFPP) on these molecules, the plasma levels of vWF, sICAM-1, sVCAM-1, and TM were measured in 4 familial hypercholesterolemia (FH) patients who underwent treatment with DFPP at 2 week intervals for more than 3 years. The levels of sVCAM-1 and sICAM-1 in hypercholesterolemia patients with ischemic heart disease as a control was 773 +/- 109 and 334 +/- 82 ng/ml. These values were higher than the normal value. In the FH patients who underwent DFPP treatment, the average sICAM-1 levels were 221 +/- 47 and 197 +/- 36 ng/ml before and after, respectively. The average sVCAM-1 levels were 601 +/- 87 and 486 +/- 60 ng/ml. There were no significant differences between the pre- and post-DFPP values. The activities of plasma vWF before and after DFPP treatment were 158 +/- 23 and 45 +/- 9%. The levels of plasma TM before and after treatment were 3.0 +/- 0.3 and 3.4 +/- 0.5 FU/ml. From these results, it is suggested that DFPP treatment does not damage the endothelium and may prevent the progression of atherosclerosis by removing the substances that induce the production of sICAM-1 and sVCAM-1 due to long-term treatment.

ABSTRACT

A comparative assessment has been made regarding efficacy and safety of the double filtration plasmapheresis (DFPP), thermofiltration (TFPP), and low-density lipoprotein (LDL) adsorptive (PA) methods by making a crossover test on heterozygous familial hypercholesterolemia patients. Treatments by DFPP, TFPP (secondary membrane Evalux 5A), and PA (Liposorber LA-40) were carried out 5 times each, with a 2-week interval, in 5 patients with heterozygous familial hypercholesterolemia. The same plasma separator (Plasmacure PS-60, polysulfone) was used in all cases, and the volume of plasma processed was set at 4 L. High removal rates were obtained of total cholesterol, LDL cholesterol, triglycerides TG, and apolipoprotein B (apoB) by all three methods, and no differences were observed. Lipoprotein (a), apoA-2, apoC-3, fibrinogen, and immunoglobulin M (IgM) showed significantly high removal rates by the DFPP and TFPP methods compared with the PA method. The sieving coefficient of albumin and high-density lipoprotein (HDL) cholesterol at 2 and 4 L of plasma processed exhibited high permeabilities using all three methods. Supplementing albumin was not necessary. An increase of the transmembrane pressure was observed in 1 case treated by DFPP but was not observed when using the TFPP or PA method. No changes were observed in serum interleukin 1beta (IL-1beta) or tumor necrosis factor-alpha (TNF-alpha) before and after treatment by any of the three methods. No remarkable side effects were observed using either the DFPP or TFPP method. The DFPP and TFPP methods showed efficacy and safety that was not inferior to the PA method in conventional LDL apheresis, and the dead-end method of the filter operation without the discarding of plasma was shown to be possible.

ABSTRACT

PURPOSE: To establish a new index of regional fat distribution using ultrasonography for assessment of the ratio of the visceral fat area (V) to the subcutaneous fat area (S) (V/S ratio). SUBJECTS AND METHODS: The subjects examined were 62 patients (23 males and 39 females); 51 patients had hyperlipidemia and 11 patients had glucose intolerance. The mean body mass indices ranged from 20.3 to 42.9. The mean age of the patients was 44 +/- 13 years. The thicknesses of the preperitoneal fat layer (P) and subcutaneous fat layer (S) in the abdomen were measured by ultrasonography and the P/S ratio was calculated. The V/S ratio was obtained with radiographic computed tomography. RESULTS: Of the various P/S ratios examined, the ratio of the maximum thickness of preperitoneal fat to the minimum thickness of subcutaneous fat was most closely correlated with the V/S ratio (r = 0.746, p < 0.0001). This ratio was termed the abdominal wall fat index (AFI). AFI was positively correlated with serum triglyceride levels and negatively correlated with high-density lipoprotein cholesterol (r = -0.312, p < 0.05), whereas the V/S ratio was correlated with triglyceride levels. AFI was positively correlated with basal insulin levels in both men and women. CONCLUSION: These results suggest that AFI measured by ultrasonography may be a new indicator of visceral fat deposition, and may reflect metabolic disorders such as lipid metabolism and glucose metabolism disorders.

ABSTRACT

The relationship between coronary stenosis and 'midband' lipoprotein, which was observed between low density lipoproteins and very low density lipoproteins by 3% polyacrylamide gel electrophoresis, was studied in patients with heterozygous familial hypercholesterolaemia (FH). The subjects were 46 patients with FH, who were evaluated by coronary angiography. The groups with and without coronary artery disease (CAD) were compared. Age, sex ratio, total cholesterol, triglyceride, HDL-cholesterol and lipoprotein(a) levels were matched in these two groups. In addition, Achilles tendon thickness and the incidence of risk factors such as diabetes mellitus, hypertension and smoking between these two groups were matched. Under these conditions, the frequency of midband was higher in the patients with CAD (20/26) than that in patients without (4/20). The results suggest that the presence of a midband among Japanese is an independent risk factor for coronary stenosis even in cases of FH who have severe hypercholesterolaemia.

ABSTRACT

The purpose of the LDL-Apheresis Regression Study (LARS) group, which included 13 institutions in Japan, was to investigate the effects on coronary atherosclerosis of LDL-apheresis combined with cholesterol-lowering drugs. Changes in coronary artery stenosis were assessed angiographically in 37 patients with familial hypercholesterolemia (7 homozygotes and 25 heterozygotes) and hypercholesterolemia which had not been defined as familial hypercholesterolemia (5 patients) by visual judgement and computer analysis. Definite regression was observed in 14 cases, including 4 homozygotes and 10 heterozygotes and others. Regression occurred as often in patients with severe coronary artery disease (2 or more vessel disease) as in those having less severe disease. Our results encourage initiation of aggressive cholesterol-lowering therapy to produce regression of coronary atherosclerosis in FH patients at high risk for cardiovascular events.
