[Successful 5'-DFUR, CDDP and MMC combination therapy and 5'-DFUR and carboplatin combination therapy for a patient with inoperable advanced gastric cancer with peritonitis carcinomatosa].

A 71-year-old man with Borrmann type 3 gastric cancer and peritonitis carcinomatosa was treated with 5'-DFUR 600 mg/body p.o. daily, CDDP 50-80 mg/m2 i.v. on day 1 and MMC 6 mg/m2 i.v. on day 2 after intraperitoneal injection of CDDP and OK-432. The cycle of CDDP and MMC was repeated every 4 or 5 weeks. After 15 cycles of treatment, the primary gastric lesion disappeared and regional lymph node metastasis was reduced. Because of relapsing of the original lesion and concomitant renal dysfunction, a changed regimen of CDDP and Carboplatin was tried. Then the gastric lesion was reduced and lymph node metastasis disappeared. The patient has lived for about 3 years after diagnosis, but his gastric lesion is gradually worsening with duodenal invasion. This case indicates that these combination chemotherapies are quite promising as an effective treatment for advanced gastric cancer and good quality of patient's life.

Collagenous colitis.

Collagenous colitis is characterized clinically by chronic watery diarrhea and pathologically by colonic mucosal subepithelial collagen deposition. We report a 72-year-old woman who had collagenous colitis associated with chronic watery diarrhea. She received a non-steroidal anti-inflammatory agent (sulindac) because of rheumatoid arthritis. Histological examination of biopsy showed a thick subepithelial collagen layer with lymphocytes, plasma cells, and infiltration of a few eosinocytes in the lamina propria. These findings led to the diagnosis of collagenous colitis. After treatment with salazosulfapyridine, her bowel movement became normalized and mucosal subepithelial collagen deposition disappeared.

Polymyositis associated with thymoma and the subsequent development of pure red cell aplasia.

A 53-year-old woman with polymyositis associated with thymoma subsequently developed pure red cell aplasia (PRCA). She was hospitalized because of fever and muscle weakness, and diagnosed as having polymyositis by muscle biopsy. Remarkable clinical improvement followed administration of prednisolone. Progressive anemia became evident, however, while prednisolone was being tapered. Erythroid aplasia and the presence of thymoma confirmed the diagnosis of PRCA. Further examinations revealed that cytotoxic T cells may play an important role in the pathogenesis of this case.

Development of transient thyroid disease and reaction during treatment of chronic hepatitis C with interferon.

Six of 50 (12%) patients with chronic hepatitis C who were treated with interferon developed thyroid disease or an autoimmune thyroid reaction while undergoing treatment. One patient developed silent thyroiditis, with an increase in serum triiodothyronine (T3), thyroxine (T4), free T3, free T4, and markedly suppressed thyroid-stimulating hormone (TSH) levels, accompanied by the appearance of both antithyroglobulin (TgAb) and antimicrosomal antibodies (McAb). One patient developed hypothyroidism in association with moderately elevated TSH levels and high titers of McAb. TSH, TgAb, and McAb levels returned to the initial values at least 4 months after the end of interferon treatment (9 months of follow up). Four patients whose TgAb and/or McAb levels were elevated during treatment with interferon had been diagnosed as having subclinical autoimmune thyroiditis; however, their thyroid function remained in the normal range. These results suggested that treatment with interferon can cause a transient autoimmune thyroid reaction and disease as a side effect.

An episode of silent thyroiditis in a patient with chronic thyroiditis and papillary adenocarcinoma following alpha interferon treatment for hepatitis C.

In the present paper we described the first case report of silent thyroiditis following alpha-interferon (IFN-alpha) treatment for chronic type C hepatitis in Japan. A 51-year-old woman with chronic type C hepatitis was treated with 6 million units of IFN-alpha three times a week for 24 weeks. Thyroid function was within normal limits and thyroid autoantibodies were negative before IFN therapy. Sixteen weeks after initiation of the treatment, she complained of increasing fatigue, palpitation and losing 7 kg in weight. Thyroid function tests at that time revealed an increase in serum T3, T4, free T3 and free T4 and a markedly suppressed TSH concentration. Both antithyroglobulin antibody (TgAb) and antimicrosomal antibody (McAb) were positive in a dilution of 1: 400. The computed tomographic (CT) scan of the thyroid showed a decrease in the CT number (Hounsfield unit; H.U.) to 58 H.U. (normal, 95-167 H.U.). The 24-h thyroid uptake of 123I was 0.75%. Aspiration biopsy specimens from a nodule in the right lobe and the remaining struma disclosed papillary adenocarcinoma and Hashimoto thyroiditis, respectively. Thyroid function spontaneously returned to normal two months after the onset of thyrotoxicosis through the subclinical hypothyroid stage. After recovery of thyroid function, patient had an operation of papillary cancer without any complications. These clinical features and laboratory findings led to the diagnosis of silent thyroiditis developing in the course of the long-term IFN therapy, which, to our knowledge, has not been reported before in Japan.

[A case of chronic fatigue syndrome who showed a beneficial effect by intravenous administration of magnesium sulphate].

We have treated a case of chronic fatigue syndrome with atopic diathesis was had suffered general malaise, low grade fever, swelling of the lymph nodes, myalgias and arthralgias for a long time. A 29-year-old female, who had been treated for atopic dermatitis for 5 years, complained of general malaise in May 1990. She was admitted to the nearest hospital in December 1990 because of low grade fever, swelling of the lymph nodes and an elevation of antinuclear antibody (2520x). She was transferred to our hospital in May 1991. A diagnosis of collagen disease was not compatible with her condition. In addition to general malaise, fever and lymph node swelling, headache, myalgias, muscle weakness, arthralgias and insomnia were observed, and a diagnosis of chronic fatigue syndrome was made based on the working case definition proposed by Holmes et al. Although eosinophilia, a high serum level of IgE, and elevation of RAST scores, low NK and ADCC activity, and a reduced level of NK cells in the peripheral blood were detected, serum antibodies to a number of viruses were in the normal range. Treatments with non-steroid anti-inflammatory drugs, minor tranquilizers and antidepressant drugs were not effective at all. An administration of magnesium sulphate was intravenously performed once a week in order to improve her condition, especially severe general malaise. After about 6-week's administration of magnesium sulphate, she noticed reduced easy fatigability and an improvement in her impaired daily activities. Finally she was able to leave the hospital in January 1992.(ABSTRACT TRUNCATED AT 250 WORDS)
