Clinical features of childhood-onset schizophrenia with obsessive-compulsive symptoms during the prodromal phase

Abstract Thirty-nine patients with schizophrenia, diagnosed according to DSM-III-R, who were under 15 years of age, were studied in two groups; 16 subjects with obsessive-compulsive symptoms during the prodromal phase, and 23 with no obsessive-compulsive disorders. The group with obsessive-compulsive symptoms during the prodromal phase was characterized by a higher ratio of males, higher incidences of perinatal and brain computed tomography (CT) abnormalities, fewer hereditary factors, longer duration of the prodromal phase, and a higher incidence of insidious onset and negative symptoms compared with the group without such prodromal symptoms. Schizophrenic patients with obsessive-compulsive symptoms during the prodromal phase were clinically distinct from those without, which suggests the possibility of subtype categorization.     

Long-term survival after bilateral adrenalectomy for metachronous adrenocortical cancer

We report the case of a female patient with bilateral metachronous adrenocortical cancer who survived long-term after adrenalectomy. In 1991, the patient underwent left adrenalectomy to remove a huge adrenal mass (10 x 9 cm) displaying no hormonal abnormality. Histological diagnosis was adrenocortical cancer. A right adrenal mass (7 x 6 cm) was found 4 years after left adrenalectomy. Right adrenalectomy was performed, and histological diagnosis was again adrenocortical cancer. The patient remains alive with no evidence of disease 8 years after last surgery.     

Characteristics of juvenile dermatomyositis in Japan

Questionnaires were sent to 1290 hospitals in Japan asking for data on patients with juvenile dermatomyositis (JDM) diagnosed between June 1984 and May 1994. Of the 204 patients identified by these questionnaires, 102 met the criteria for JDM. JDM is categorized into three subtypes: Banker-type JDM , Brunsting-type and fulminant-type; patients with the latter exhibit markedly elevated serum levels of creatinine phosphokinase (> 10 000 U/mL) and appear to be at risk of renal failure. Cutaneous manifestations were present in 98% of patients and preceded the appearance of other symptoms. This tendency is one of the reasons for the difficulty in some cases in diagnosing the onset of JDM. Better criteria for early treatment of JDM are needed. The results of the present study suggest that itching and calcinosis are factors that indicate a poor prognosis in patients with JDM. Muscle enzyme levels do not always reflect disease activity, suggesting that methods other than measurement of muscle enzymes, such as measurement of the levels of neoprerin and von Willebrand factor antigen, as well as magnetic resonance imaging should be used to be evaluate disease severity. Patients with Brunsting-type JDM who exhibit dysphagia and antinuclear antibody positivity and patients with Banker-type JDM should be treated aggressively. Pulse therapy should be selected as the initial therapy in patients with fulminant-type JDM.     

Theophylline metabolism in acute asthma with MxA-indicated viral infection

BACKGROUND: Although viral infection might alter theophylline metabolism in acute asthma, there are some difficulties in detecting infection due to various kinds of viruses in a clinical setting. METHODS: To evaluate the usefulness of assessment of MxA protein in acute asthma exacerbated by viral infection, MxA protein expression in lymphocytes was assayed by flow cytometric analysis in whole peripheral blood in 21 children (aged 0-6 years) receiving continuous theophylline infusion for management of asthma attack. Serum theophylline levels were measured at 24 and 72 h after initiating theophylline infusion. RESULTS: At the beginning of theophylline infusion, 11 children had increased expression of MxA protein, indicating viral infected states. After 24 h continuous infusion, there were no differences in theophylline levels between MxA-negative and MxA-positive groups. After 72 h infusion, the mean theophylline level of MxA-positive children was significantly higher than that of MxA-negative children (9.7 +/- 2.2 microg/mL vs 7.3 +/- 1.6 microg/mL). The ratio of theophylline clearance at 72 h to that at 24 h in the MxA-positive group was significantly lower than that of the MxA-negative group (1.1 +/- 0.2 vs 1.4 +/- 0.1). CONCLUSIONS: Viral infection appeared to affect theophylline metabolism. Flow cytometric assay of lymphoid MxA protein expression in whole blood is an easy and useful method of evaluating viral infection in acute asthma exacerbation.     

Utility of immunohistochemical detection of prostate-specific Ets for the diagnosis of benign and malignant prostatic epithelial lesions

BACKGROUND: Human prostate-specific Ets (hPSE) belongs to the Ets family. It regulates the proliferation, differentiation, and development of prostate epithelial cells. A recent study showed that hPSE can be detected in normal glands but not in cell lines established from prostate cancer (PCA), suggesting a translational disorder of hPSE from mRNA to protein in PCA. Immunohistochemical detection of hPSE could therefore be another method of differential diagnosis of PCA from other proliferative conditions in the prostate. METHODS: An immunohistochemical detection of hPSE was carried out on the whole mounted prostatectomy specimen obtained from 19 cases with PCA. RESULTS: Basal and secretory luminar cells showed a diffuse cytoplasmic staining for hPSE in normal glands, hyperplastic glands, and prostate intraepithelial neoplasia lesions. Whereas approximately 30% of PCA lesions showed a negative staining for hPSE, the positive rate for hPSE between PCA and benign glands or prostate intraepithelial neoplasia (PIN), was statistically significant (P < 0.05). Staining intensities in normal glands, hyperplastic glands, and PIN lesions were similar, but generally stronger than those in PCA lesions. CONCLUSIONS: Negative immunoreactivity for hPSE strongly suggests malignancy in the prostate glands. Decreased immunoreactivities of glands for hPSE could suggest PCA.

Estimation of myocardial damage in Kawasaki disease using antimyosin antibody

In a retrospective study, 121 children with Kawasaki disease (KD) were investigated to determine (i) the incidence of myocardial damage using the antimyosin antibody (AMA) titer; (ii) the differences in the electrocardiograms between the AMA-positive and -negative patients; and (iii) the effect of treatment with intravenous gamma globulin (IVGG) on the AMA. Comparisons were made with 117 normal children (controls). Patients with KD showed a significantly higher mean AMA titer and more patients were positive for AMA than the controls. The AMA titer in the KD group was not related to the presence of coronary artery lesions. Electrocardiograms obtained during the acute and the convalescent stage of KD revealed that patients positive for AMA had a significantly lower voltage of T wave in lead V6 at week four than at week two of illness, whereas patients negative for AMA showed no T wave change after week two. The group treated with IVGG showed a significantly lower AMA titer than that not given IVGG. These observations suggest that myocardial damage occurs in some patients with KD which is unrelated to the presence of coronary artery lesions and that the treatment with IVGG reduces the AMA titer in patients with KD.
