BACKGROUND: In an effort to improve the quality of life of children with cancer, this study analyzes the signs and symptoms at the end of life in such children. It is hoped that these data will contribute to the development of appropriate programs to address the challenges faced by these children. PROCEDURE: Between 1994 and 2000, 28 children died after treatment for cancer at Hamamatsu University Hospital, Japan. The circumstances, signs and symptoms at the end of life of these children were analyzed through their medical records. RESULTS: Of the 28 children, the underlying diseases were leukemia/lymphoma (LL group; n=11), brain tumors (BT group; n=7), and other solid tumors (OST group; n=10). Records showed poor appetite (100%), dyspnea (82.1%), pain (75.0%), fatigue (71.4%), nausea/vomiting (57.1%), constipation (46.4%) and diarrhea (21.4%) among these children. Anxiety was reported in 53.6% of the entire group of 28 children; however, no child in the BT group manifested anxiety. However, disturbance of consciousness was reported in all children in the BT group, which was significantly greater than in the other groups. Awareness, fear or acceptance of the imminence of his/her own death as indicated by verbal expression was reported in nine children (32.1%). CONCLUSIONS: Using the data obtained in the present study, we describe situations faced in the terminal care of children. It is important to address the problems revealed by this analysis in order to achieve improvements in both the physical and psychological care of children with terminal cancer. 相似文献

Cyclic AMP (cAMP) output in the duodenal contents of 11 normal subjects, 18 patients with chronic pancreatitis, six convalescing from acute pancreatitis and five with pancreatic carcinoma was measured after a single dose of pancreozymin and secretin. The technic was indirect, utilizing recovery of duodenal contents by the Dreiling tube rather than direct measurements of fluid that was not contaminated by bile. In all patients groups, cAMP output reached a peak after this stimulation with a concomitant increase of bicarbonate and amylase outputs. A significantly decreased cAMP output was observed in all pancreatic disease groups compared to the normal group. Patients with chronic pancreatitis showed a slightly decreased cAMP output, considerably decreased bicarbonate output and normal amylase output. In acute pancreatitis cAMP output was reduced with normal bicarbonate and amylase outputs. In pancreatic carcinoma cAMP decreased significantly, bicarbonate output was moderately reduced and amylase output was normal. cAMP output in all groups studied did not correlate with either bicarbonate output or amylase output. 相似文献

Both eosinophils and specific immunoglobulin E (IgE) to foods and mites have been considered involved in the pathogenesis of atopic dermatitis (AD). The relationship between eosinophils and specific IgE, however, remains to be elucidated. Blood eosinophil counts, serum eosinophil cationic protein (ECP) and IgE to egg white, cow's milk, soybean, rice and Dermatophagoides pteronyssinus (Dp) were measured in subjects with AD alone or bronchial asthma (BA) alone. Subjects with positive IgE titers (Pharmacia radioallergosorbent test (RAST) units > 0.7) of one or more items were defined as RAST-positive. Immunoglobulin E titers to egg white, cow's milk and soybean of subjects with AD were high in early childhood and declined with aging, whereas the titers of subjects with BA were negative or low. Immunoglobulin E titers to Dp were elevated after 1 year of age in both disease groups. Eosinophil cationic protein (ECP) levels and blood eosinophil counts in the AD and BA groups were significantly higher than those of non-atopic controls. No difference in ECP levels or blood eosinophil counts were observed between RAST-positive and negative groups. It is concluded that IgE to foods such as egg white, cow's milk and soybean might have a role in the pathogenesis of AD of young children, while IgE to mites might be involved in older children. Eosinophils may also participate in AD. However, different mechanisms may be responsible for the rise in specific IgE and high ECP levels and blood eosinophil counts. 相似文献

Acute stomach, kidney, and bladder toxicity was evaluated inF344 rats after gastric gavage of tetraethylorthosilicate (TES)at daily doses of 0, 0.111, 0.223, and 0.333 g. Five rats ofeach sex at each dose were sacrificed after 1, 2, and 4 days.In TES-treated groups, silicate accumulated in the stomach glandsand the muscle layer of the forestomach and glandular stomach.Serum chemistries demonstrated acute onset of renal failure.In the kidneys, acute tubular necrosis, accumulation of silicates,and superficial necrotizing papillitis were observed. In therenal pelvis and bladder, there was urothelial simple hyperplasia,focal erosion of the mucosa, edema, and inflammation. Theseacute toxic changes were dose and time dependent, but significantsex differences were not observed. The microscopic changes inthe urothelium were similar to those observed following administrationof high doses of sodium saccharin to male rats in which urinarysilicate precipitate and crystals form. 相似文献

AIM: It has been proposed that gonadotropin-releasing hormone (GnRH) analog administered after testicular damage stimulates the recovery of spermatogenesis. However, GnRH analogs suppress the function of sex accessory organs. In this study, we investigated whether testosterone also stimulates the regeneration of rat spermatogenesis after exposure to busulfan. METHODS: Male Fisher rats were divided into three groups of five each and all rats were treated with busulfan, 25 mg/kg, intraperitoneally at week 0. Group A served as the control. The other two groups received testosterone enanthate, 8 mg/kg, subcutaneous injections at 3 week intervals two times before (group B) or three times after (group C) busulfan. States of spermatogenesis were evaluated by histology and by the number of spermatid nuclei per testis at week 25. RESULTS: The mean percentage of 'recovered' seminiferous tubules plus or minus standard deviation was 10.3 +/- 7.8% in group A and 2.1 +/- 1.2% in group B. In both groups, more than 80% of the tubules remained degenerated. However, testes of group C rats showed an improvement of up to 37.1 +/- 20.5% (P < 0.05). The significant recovery of spermatogenesis was also demonstrated in group C by counting the number of spermatid nuclei per testis ([78.8 +/- 57.5] x 106). However, the count was only (7.6 +/- 13.5) x 106 and (0.52 +/- 1.0) x 106 in group A and B, respectively. CONCLUSIONS: Testosterone administration after severe testicular damage enhanced the regeneration of spermatogenesis in rats. We assumed that supplementary doses of testosterone would be more practical for clinical application than GnRH analogs, because exogenous testosterone maintains androgenicity. 相似文献

Abstract In the present study, the effect of methamphetamine (MAP) on histamine (HA) release measured by in vivo brain microdialysis in the rat hypothalamus was investigated. Administration of MAP (3 mg/kg) significantly increase HA release from 40 to 160 min after the injection. This finding suggests that a moderate dose of MAP activates the hypothalamic HA neuron system, which may be related to effects of MAP on intrinsic biological rhythms. 相似文献

Accidental transmission of contagious pathogens, especially hepatitis C virus (HCV), by needlestick or other means as an occupational hazard for medical staff is of concern. We retrospectively analysed cases of work-related accidental injury with pathogens such as hepatitis B virus (HBV), HCV, syphilis and human immunode?ciency virus (HIV) reported to the centres for disease control at 15 hospitals (total 5776 beds) in the Gunma prefecture, Japan, from December 1990 to August 1993 (24.7 months). There were 416 such cases (16.8 cases/month), with an incidence of 0.2–3.5 accidents per month per hospital. Such accidents occurred in 297 (71.2%) nurses, 98 (23.5%) medical doctors, 13 (3%) laboratory technicians, four (1.0%) hospital maintenance workers, one (0.2%) assistant nurse, one secretary and two others. There were 323 (77.6%) injuries caused by needlestick, 42 (10.1%) from suture needles or surgical knife cuts, 17 (4.1%) from blood splatters from patients into the eyes or mouth, 10 (2.4%) from contact with injured skin and 24 (5.8%) simple skin contacts. Of the pathogens, 60.3% were HCV, 22.6% HBV, 5.8% syphilis, 0.7% HIV and 10.6% were of unknown origin. Four cases (1.6%) of HCV infection were found and treated with one or two courses of interferon therapy, and HCV was subsequently cleared. All four patients were cured with interferon therapy. None of the HBV-injured cases resulted in infection, possibly because of prophylaxis with HB immunoglobulin and HB vaccine. No HIV or syphilis infection was contracted. In summary, chronic HCV infection acquired as an occupational hazard can be cured by appropriate treatment, such as with interferon, after early detection of the infection. 相似文献

A rare case of gastrojejunul fistula secondary to gastric cancer is presented. Fluoroscopic examination visualized the passage of contrast medium from the stomach to the small intestine. Gastric fiberscopy revealed cancer on the greater curvature of the corpus perforation into the jejunum. The scope could be inserted readily into jejunum through this perforation. Laparotomy showed that the cancer infiltrated and perforated from the stomach to the jejunum at about 10 cm. from the ligament of Treitz. Distal gastrectomy and resection of 10 cm. of the perforated jejunum were performed. The resected specimen revealed a Borrmann III gastric cancer of the greater curvature perforating the jejunum. 相似文献

The gene frequency (+/- SD) of SB alleles was estimated in the Japanese population as follows: SB1 0.00, SB2 0.195 +/- 0.027, SB3 0.070 +/- 0.017, SB4 0.091 +/- 0.019, SB5 0.335 +/- 0.034 and SB blank 0.308 +/- 0.035. The absence of SB1 allele, decrease of SB4 allele and increase of SB5 allele are characteristic features of the SB system in the Japanese population as compared with Caucasians. 相似文献

Abstract A patient with atypical multiple sclerosis (MS) with clear concentric structure was studied using high field magnetic resonance imaging (MRI). This case was considered to be Balo's concentric sclerosis. Magnetic resonance imaging showed diffuse multiple concentric demyelinating lesions in the bilateral centrum semiovales, which finally regressed with the necrotic lesions remaining when the patient was discharged. During his clinical course, he showed some higher cerebral dysfunctions, such as memory disturbance, constructual apraxia and acalculia. He was treated with glycerin, prednisone and rehabilitation; all of which were effective in his recovery. Over a 4 month period, the patient recoveredclinically, but some intellectual impairment remained. 相似文献
