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.     

Prostaglandin E1‐effective,transient‐type ischemic colitis developed after surgical resection of sigmoid colon cancer. A case report

A 55‐year‐old‐man had a laparoscopic resection of the sigmoid colon due to colon cancer with submucosal invasion. After the surgery he suffered ileus and had a laparotomy. Six months later he complained of frequent defecation. Colonoscopy confirmed a circular ulcer extending from the anal side of the anastomosis in the sigmoid colon to the mid rectum. Endoscopic ultrasound demonstrated thickening of all layers of the diseased colon and rectum. We diagnosed ischemic colitis. After intravenous drip infusion of prostaglandin, symptoms and colonic stricture gradually improved. Although abdominal angiography revealed a narrowing of the peripheral sigmoid branch of the inferior mesenteric artery, blood flow was unrestricted. Colonoscopy performed 84 days after discharge revealed an ulcer scar.     

Experimental myelitis caused by herpes simplex virus type 2 in C57BL/6N and BALB/cN mice

Intraperitoneal and intracranial inoculation of herpes simplex virus type 2 (HSV 2) into BALB/cN and C57BL/6N mice was carried out to induce experimental myelitis. The myelitis was clearly observed in C57BL/6N mice following intraperitoneal inoculation. Within 24 hours before death, the mice showed urinary and rectal incontinence and paraplegia of the hind legs. Randomly distributed, severe necrosis was demonstrated in the spinal cord, mainly at the lower cord. In BALB/cN mice the clinical symptoms were not clearly observed, as the mice died shortly after their onset. Although spinal cord necrosis was more prominent in C57BL/6N mice than BALB/cN mice, brain necrosis was only found in the latter, and not in the former. Both strains of mouse showed marked nuclear pyknosis of the nerve cells and slight nuclear pyknosis of the astrocytes in the brain where HSV 2 antigen was demonstrated immunohistochemically. The antigen was also detected in the necrotic spinal cord. In contrast, intracranial inoculation of the virus into both strains did not cause myelitis. Spinal cord necrosis was not demonstrated and virus DNA was not detected, by PCR, in spinal cord samples. In the brain, however, the virus was demonstrated by both PCR and immunohistochemistry.

The enzymatic basis for the conversion of nonfucosylated to fucosylated alpha-fetoprotein by acyclic retinoid treatment in human hepatoma cells: activation of alpha1-6 fucosyltransferase.

The purpose of the present study was to investigate the mechanism by which nonfucosylated alpha-fetoprotein (AFP) is converted to fucosylated AFP in human hepatoma cell lines exposed to acyclic retinoid (AR), an effective drug for the secondary prevention of hepatocellular carcinoma. AR treatment (100 microM) of HepG2 and Hep3B cells significantly increased the activity and mRNA levels of alpha1-6 fucosyltransferase (alpha1-6 FucT), the enzyme responsible for the fucosylation of AFP, leading to an increase in fucosylated glycoproteins as evidenced by lectin binding measurements. Lectin immunoelectrophoresis of AFP obtained from culture media indicated that the relative percentage of nonfucosylated AFP (L1 fraction) was decreased and alpha1-6 fucosylated AFP (L3 fraction) was increased in these hepatoma cell lines after treatment with AR. The total AFP levels were, however, markedly suppressed by AR treatment, and therefore the absolute L3 fraction on the basis of the total AFP present was extremely low. These results demonstrate that AR enhances the conversion of the L1 to the L3 fraction due to the activation of alpha1-6 FucT in human hepatoma cell lines despite clinical outcome with AR treatment and the L3 fraction of AFP. Even though the dramatic decrease in AFP is the limiting factor in the synthesis of the L3 fraction and, therefore, the absolute value of fucosylated AFP is extremely low, the conversion from L1 to L3 as judged by lectin immunoelectrophoresis represents a good marker for the progress of AR treatment.     

Influence of cefotiam (SCE-963, CTM) on bowel flora (author's transl)

The influence on bowel flora of CTM was studied in 5 children who were taking normal diet. 1) In the cases following no diarrhea, administration of CTM caused no significant changes in bowel flora. In the cases following diarrhea, administration of CTM caused a fall in coliform, BEP group, Lactobacillus and Peptostreptococcus. However, after the administration was discontinued, the reduced bowel flora was returned to the normal range within a few days. 2) No overgrowth of bowel flora by Pseudomonas, Clostridium difficile or Candida was observed. 3) One strain of nontoxigenic Clostridium difficile was observed in the case of following no diarrhea. 4) As for the side effects, diarrhea was observed in 2 cases. BEP group: Nonspore making anaerobic Gram positive rods of Bifidobacterium, Eubacterium, Propionibacterium.     

Family experience with palliative sedation therapy for terminally ill cancer patients

Symptomatic sedation is often required in terminally ill cancer patients, and could cause significant distress to their family. The aims of this study were to clarify the family experience during palliative sedation therapy, including their satisfaction and distress levels, and the determinants of family dissatisfaction and high-level distress. A multicenter questionnaire survey assessed 280 bereaved families of cancer patients who received sedation in 7 palliative care units in Japan. A total of 185 responses were analyzed (response rate, 73%). The families reported that 69% of the patients were considerably or very distressed before sedation. Fifty-five percent of the patients expressed an explicit wish for sedation, and 89% of families were clearly informed. Overall, 78% of the families were satisfied with the treatment, whereas 25% expressed a high level of emotional distress. The independent determinants of low levels of family satisfaction were: poor symptom palliation after sedation, insufficient information-giving, concerns that sedation might shorten the patient's life, and feelings that there might be other ways to achieve symptom relief. The independent determinants of high levels of family distress were: poor symptom palliation after sedation, feeling the burden of responsibility for the decision, feeling unprepared for changes in the patient's condition, feeling that the physicians and nurses were not sufficiently compassionate, and shorter interval to patient death. Palliative sedation therapy was principally performed to relieve severe suffering based on family and patient consent. Although the majority of families were comfortable with this practice, clinicians should minimize family distress by regular monitoring of patient distress and timely modification of sedation protocols, providing sufficient information, sharing the responsibility of the decision, facilitating grief, and providing emotional support.     

Existential concerns of terminally ill cancer patients receiving specialized palliative care in Japan

Background Although alleviation of existential distress is important for terminally ill cancer patients, the concept of existential distress has not been fully understood. The aim of this study was to categorize existential concerns of Japanese terminally ill cancer patients and explore care strategies based on the categorizations.Methods A multicenter cross-sectional study in 88 terminally ill cancer patients receiving specialized inpatient palliative care was performed. The nurses explored patient existential concerns by asking several key questions, and recorded the answers that they considered typically described the patients concerns. All statements recorded by the nurses were analyzed using content analysis methods.Results A total of 89 statements were subjected to analysis. The categories and their prevalence were: relationship-related concerns (22%; isolation, concerns about family preparation, conflicts in relationship), loss of control (16%; physical control, cognitive control, control over future), burden on others (4.5%), loss of continuity (10%; loss of role, loss of enjoyable activity, loss of being oneself), uncompleted life task (6.8%), hope/hopelessness (17%), and acceptance/preparation (25%).Conclusions Existential concerns of Japanese terminally ill cancer patients were categorized as relationship-related concerns, loss of control, burden on others, loss of continuity, uncompleted life task, hope/hopelessness, and acceptance/preparation. These themes seemed to encompass universal human suffering beyond cultural differences, and this conceptualization may contribute to the development of effective therapeutic interventions to alleviate existential distress.This is work is presented on behalf of the Japan Pain, Rehabilitation, Palliative Medicine, and Psycho-Oncology (J-PRPP) Study Group.The study was supported by Health and Labor Sciences Research Grants, Clinical Research for Evidenced Based Medicine (2002).     

Serum erythropoietin levels for predicting bone marrow recovery following chemotherapy in leukaemia

Summary To investigate whether serum erythropoietin (EPO) levels are influenced by the intensity of bone marrow erythroid activity, we used a radioimmunoassay (Nippon DPC Co., Japan) to study EPO levels in three acute leukaemia patients during treatment with intensive chemotherapy. We also measured the reticulocyte count and reticulocyte maturity using an automated reticulocyte analyser (Sysmex R-2000) to detect erythropoietic activity. From the day after the initiation of chemotherapy, EPO levels increased markedly without any change in Hb levels, suggesting that some other mechanism was regulating serum EPO. A decrease in EPO after chemotherapy was accompanied by an increase in high fluorescence ratio, an index of immature reticulocvtes, but the actual increase in the reticulocyte count was delayed for 3-4 days after this. These findings suggest that the decrease in serum EPO levels was closely related to the early stage of red cell production and that EPO levels may be a useful marker for the recovery of erythropoietic activity after chemotherapy.
