Prenatal findings in congenital leukemia: a case report.

We here describe a case of congenital leukemia that ended in intrauterine fetal demise at 30 weeks of gestation. Acute enlargement of the fetal trunk, elevated pulsatility index of the umbilical artery with concomitant decline of pulsatility index of the middle cerebral artery, pleural effusion, and polyhydramnios preceded the fetal death. Diagnosis of congenital myeloid leukemia was suggested by microscopic examination of the placental tissue, revealing immature myeloid precursors filling the lumina of fetal vessels in the umbilical cord and chorionic villi.

[Mobile-phone e-mail use, social networks, and loneliness among Japanese high school students].

Purpose: The purposes of this study were to assess the loneliness of Japanese high school students who own and use a mobile phone, to clarify the relationships between students' loneliness and their social network and frequency of use of e-mail feature, and to demonstrate relationships with a student's social network and recognition of the benefits and drawbacks of mobile phone use.

Method: The participants were 227 students from two classes in each grade of a high school in the Kanto region of Japan. Participants answered a questionnaire covering the UCLA Loneliness Scale as well as questions pertaining to the circumstances of use of their mobile phones, their social networks (e.

Usefulness of the 2nd generation assay for anti-TSH receptor antibodies to differentiate relapse of Graves' thyrotoxicosis from development of painless thyroiditis after antithyroid drug treatment for Graves' disease.

After antithyroid drug (ATD) treatment for Graves' disease, either a relapse of Graves' thyrotoxicosis or painless thyroiditis can develop. It is important to differentiate these two types of thyrotoxicosis because of the difference in required therapy. However, differentiation of thyrotoxicosis is usually difficult without radioactive iodine uptake (RAIU) which is not available in general practice.

[Differential diagnosis of hepatitis: development of new laboratory tests for autoimmune hepatitis and progress in pathophysiology].

Liver dysfunction has been found in 8.1% of postpartum women in the general population. This dysfunction was speculated to be developed by postpartum aggravation of subclinical autoimmune hepatitis.

Relation between post-partum liver dysfunction and anti-cytochrome 2D6 antibodies.

Problem: Autoimmune thyroid disease frequently aggravates or develops after delivery through the immune rebound mechanism. However, little is known about the post-partum development of autoimmune hepatitis (AIH).

Method Of Study: We examined 18 patients who developed liver dysfunction after delivery or abortion.

No increase of blocking type anti-thyrotropin receptor antibodies during pregnancy in patients with Graves' disease.

Serial changes in serum levels of anti-TSH receptor antibodies were examined during and after pregnancy in six patients with Graves' disease receiving no or minimal maintenance doses of antithyroid drugs. During pregnancy, serum levels of TSH-binding inhibitory Igs (P < 0.001) and thyroid-stimulating antibodies (TSAbs) (P < 0.

Possible induction of Graves' disease and painless thyroiditis by gonadotropin-releasing hormone analogues.

Prolonged administration of gonadotropin-releasing hormone (GnRH) analogues induce a decrease in serum estrogen level, which may aggravate subclinical or mild autoimmune thyroid disease. Two patients developed Graves' thyrotoxicosis in association with an increase in anti-thyrotropin (TSH) receptor antibody activities at 4 months after initiation of buserelin acetate. GnRH analogue therapy was discontinued at the time of diagnosis but it took more than 2 years of methimazole therapy to obtain remission of Graves' disease.

Association of seasonal allergic rhinitis is high in Graves' disease and low in painless thyroiditis.

Hashimoto's thyroiditis is thought to be a T-helper cell type 1 (TH1)-dependent disease, but it is not clear whether Graves' disease is T-helper cell type 2 (TH2)-predominant or not. TH1-predominant diseases are infrequently and TH2-predominant diseases are frequently associated with allergic diseases. We examined the prevalence of seasonal allergic rhinitis to Japanese cedar pollen, a typical TH2-associated disease, in patients with Graves' disease (n = 126), painless thyroiditis (n = 46) and Hashimoto's thyroiditis (n = 88), and compared them to healthy controls (n = 766).

Practical treatment with minimum maintenance dose of anti-thyroid drugs for prediction of remission in Graves' disease.

Although many researchers have reported clinical and laboratory parameters for prediction of remission in Graves' disease during or after anti-thyroid drug therapy, there is no reliable one to assure the complete remission. We prospectively examined a practical therapy with minimum maintenance dose of anti-thyroid drugs for prediction of remission in Graves' disease. Fifty-seven patients with Graves' disease were treated with anti-thyroid drugs at the initial dose of 30 mg/day of methimazole (MMI) or 300 mg/day of propylthiouracil (PTU).

Increased serum concentration of eosinophil-derived neurotoxin in patients with Graves' disease.

Eosinophil-derived neurotoxin (EDN) is released after activation and stimulation of eosinophils in allergic disease, which is a T(H)2-predominant condition. We previously reported that Graves' thyrotoxicosis develops or relapses after an attack of allergic rhinitis. In this study, to confirm the relation between Graves' disease and the allergic condition, we determined the serum level of EDN in 30 untreated patients with Graves' disease, 50 patients with Hashimoto's thyroiditis, and 39 normal controls.

Blocking-type anti-TSH receptor antibodies and relation to responsiveness to antithyroid drug therapy and remission in Graves' disease.

Objective: Antithyroid drugs are effective in some patients with Graves' disease but not in others. The factors responsible for this difference are still unknown. We examined the relationship between the nature of anti-TSH receptor (TSH-R) antibodies and responsiveness to drugs in Graves' disease.

Simple and practical parameters for differentiation between destruction-induced thyrotoxicosis and Graves' thyrotoxicosis.

Objective: Differentiation of destruction-induced thyrotoxicosis from Graves' thyrotoxicosis is important for selection of therapy. It is, however, often difficult to make this distinction without measurement of radioactive iodine uptake. We searched for simple and practical parameters that might allow differentiation between the two entities.

Anti-CYP2D6 antibodies detected by quantitative radioligand assay and relation to antibodies to liver-specific arginase in patients with autoimmune hepatitis.

Background: Antibodies to cytochrome P4502D6 (CYP2D6) were measured and their prevalence compared with that of antibodies to liver-specific arginase in patients with autoimmune hepatitis (AIH).

Methods: Anti-CYP2D6 antibodies were measured by sensitive radioligand assay and enzyme-linked immunosorbent assay (ELISA), and anti-arginase antibodies were measured by ELISA in 132 patients (definite AIH 11, probable AIH 36, hepatitis C 20, hepatitis B 23, other autoimmune diseases 42) and 50 healthy controls.

Results: CYP2D6 index (radioligand assay) was significantly higher in all groups of patients than those in healthy controls.
