We studied the effect of the photosensitizing agent 5-aminolevulinic acid (5-ALA) in both in vitro and in vivo models.Methods: The in vitro photosensitizing activity of 5-ALA was examined in a microvascular endothelial cell (MEC) culture system. 5-ALA was added in various concentrations and the cells were illuminated at 630 nm. The percentage of MEC killed was measured by either a Live/Dead assay or an lactate dehydrogenase (LDH) assay. The effect of varying the light energy dose delivered at 630 nm after the administration of 5-ALA was studied by determining the amount of necrosis produced in chicken combs.Results: The combination of 5-ALA at a concentration of 35 micrograms/ml, and illumination by 100 mW/cm2 of laser light at 630 nm wavelength, caused 50% cell kill in the MEC culture system. Chicken combs of animals that received 200 mg/kg of 5-ALA and illumination at a power density of 80 mW/cm2 had a depth of injury of 362.5 +/- 27.6 microns upon histological examination. Those combs that received 100 or 120 mW/cm2 showed a depth of injury of 732.5 +/- 29.1 and 792.5 +/- 36.0 microns respectively.Conclusion: 5-ALA is effective in sensitizing human MEC to laser illumination. However, the degree of absorption and tissue destruction in different anatomical structures should be considered in future clinical studies.","PeriodicalId":77066,"journal":{"name":"Changgeng yi xue za zhi","volume":"22 2","pages":"181-8"},"PeriodicalIF":0.0,"publicationDate":"1999-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21356041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many explanations of the pathogenesis, but none are conclusive. Different treatments have been applied, but they generally remain obscure and disappointing. Transvestic fetishists rarely seek psychotherapy, because of their dynamic balance between perversion and intrapsychic disintegration. There are few studies, either qualitative or quantitative, associated with transvestic fetishism in Taiwan. This case report describes an adolescent transvestic fetishist who underwent a brief course of psychotherapy in the outpatient department of a psychiatric center in Taipei. After consultation for one year, he still maintained his deviant sexual behavior but also developed more severe moral anxiety. He was then referred for psychotherapy. Cognitive-behavioral and psychodynamic theories associated with transvestic fetishism were reviewed and applied in both understanding and treating this client. Some temporal effectiveness was achieved with combined cognitive-behavioral and dynamic-oriented supportive psychotherapy. After 18 sessions of psychotherapy over more than 4 months, the client was able to stop his perverse behavior and have fewer sexually arousing fantasies. The prognosis of transvestic fetishism is generally supposed to be pessimistic and have a high rate of recurrence. Some propose that adolescents have a better outcome after treatment. This case report reveals the possibility of change for a transvestic fetishist. However, the long-term effects of the brief course of psychotherapy require further evaluation in the future.","PeriodicalId":77066,"journal":{"name":"Changgeng yi xue za zhi","volume":"22 2","pages":"299-312"},"PeriodicalIF":0.0,"publicationDate":"1999-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21357050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Multimodal approach of cranial ultrasound in children.","authors":"H S Wang, M F Kuo","doi":"","DOIUrl":"","url":null,"abstract":"The potential uses of cranial ultrasound have been overlooked for years because of the advent of fascinating neuroimaging studies such as computed tomography (CT) and magnetic resonance imaging (MRI) study. In this article, the authors introduce the developments and refinement in modern pediatric neurosonology. In the past, only neonates with widely open fontanels seemed to be good candidates for cranial ultrasound study. Actually, any tiny skull defect can be used as an acoustic window. And the thin skulls of children do not hinder the ability of ultrasound to obtain acceptable image transcranially. Today, many CT and MRI studies can be replaced with the advanced cranial ultrasound if clinicians or neurologists recognize the advantages. Cranial ultrasound can provide Doppler hemodynamic studies which CT and MRI can not. Only ultrasound can provide convenient, real-time intraoperative guidance and continuous bedside monitoring in patients who need neurological intensive care. Cranial ultrasound also plays an important role in follow-up studies because it is convenient, economical, and safe, especially in children. To obtain all the benefits from an ultrasound study, one has to realize the \"multimodal\" applications of it, including the applications of all acoustic windows, multifrequency transducers, and hemodynamic study with the aid of power Doppler and contrast agents. With a multimodal approach, physicians can achieve the utmost from the powerful modern cranial ultrasound in pediatric patients.","PeriodicalId":77066,"journal":{"name":"Changgeng yi xue za zhi","volume":"22 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"1999-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21284217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decreased N-acetylaspartate (NAA) and increased choline-containing compounds (Cho) and creatine-phosphocreatine (Cr) have been found in the hippocampus of patients with complex partial seizures (CPS).Methods: We prospectively studied hippocampal proton MRS of 10 patients with CPS and 12 control subjects by using the chemical shift imaging (CSI) technique. The spectral data were analyzed in terms of the ratio between the integral peak area of NAA and that of (Cho + Cr).Results: Compared with the control group, patients with CPS showed a significantly lower NAA/(Cho + Cr) ratio, both in the anterior and posterior hippocampus (p value = 0.001 and 0.002, respectively). Metabolic abnormalities of the hippocampus were detected using proton CSI in all the patients with normal MRI results (4 patients) and those with normal EEG results (3 patients). Lateralizations using proton CSI were obtained in all the 10 patients in this study, including concordant lateralization in the 6 patients with MRI-detectable abnormalities.Conclusion: The hippocampal abnormalities in patients with CPS can be detected early using proton CSI than using MRI or surface EEG. Lateralization of the seizure focus using proton CSI is possible, but further correlation with the surgical outcome in a larger study group is necessary.","PeriodicalId":77066,"journal":{"name":"Changgeng yi xue za zhi","volume":"22 1","pages":"68-75"},"PeriodicalIF":0.0,"publicationDate":"1999-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21285315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Any delay in diagnosis or treatment aggravates the patient's outcome. Owing to the scarcity of reports concerning ischemic bowel disease in chronic dialysis patients, we investigated the ischemic bowel disease in chronic dialysis patients.Methods: From January 1986 through April 1997, medical records of 2416 chronic dialysis patients at our hospital were reviewed. Among them, 5 patients with surgically documented ischemic bowel disease were enrolled. The clinical manifestations, laboratory findings, operative findings, pathologic test results and prognoses of these patients are reported.Results: Abdominal pain, abdominal distension and bloody stool were major initial presentations. The mean age of the patients was 62.4 years at the time of diagnosis of ischemia. All patients had hypertension, 3 patients had hyperlipidemia, three patients had diabetes mellitus and three patients had history of shunt occlusion. Four patients had leukocytosis. Image studies revealed dilatation of bowel loops in four patients. Peritonitis made exploratory laparotomy necessary. The findings during operation showed turbid ascites and variable degrees of bowel ischemia or gangrene. The methods of surgical intervention depended on the severity of the disease. Only one patient died due to extensive ischemic bowel involvement and subsequent sepsis.Conclusion: It is mandatory to have an index suggestive of ischemic bowel disease in chronic dialysis patients with unexplained abdominal pain or discomfort. Early diagnosis and aggressive surgical intervention is the cure modality for patients with acute ischemic bowel disease.","PeriodicalId":77066,"journal":{"name":"Changgeng yi xue za zhi","volume":"22 1","pages":"82-7"},"PeriodicalIF":0.0,"publicationDate":"1999-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21285317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There were 12 male and 12 female patients with a mean age of 42 years (range: 23 to 72 years). The anorectal manometry was performed one day before the operation and 8 to 12 weeks after the operation. Another normal group, comprised of 138 volunteers, was included and matched for age and gender.Results: The anorectal inhibitory reflex was present in all the normal group (NG), symptomatic hemorrhoid (SH), and post-hemorrhoidectomy (PH) patients. No major incontinence was noted clinically. The mean resting pressure (MRP) in the SH group (mean: 84.5 +/- 28.7 cmH2O, range: 26 to 166 cmH2O) was significantly greater than in the NG (mean: 74.4 +/- 14.9 cmH2O, range: 61 to 116 cmH2O) and the PH groups (mean: 63.7 +/- 23.6 cmH2O, range: 20 to 116 cmH2O) (p = 0.032 and 0.005, respectively). After hemorrhoidectomy, the MRP was significantly decreased compared to the normal group (p = 0.018). The other manometric data showed no statistical change in these three groups.Conclusion: The results indicate that persons with SH have a higher MRP than normal. Overactivity of the internal sphincter muscle may be a cause rather than a result of symptomatic hemorrhoids. Compared with the SH and normal groups, the MRP was significantly decreased to prevent recurrent symptomatic hemorrhoids in the PH group. Though the MRP was significantly decreased, no major incontinence was noted after hemorrhoidectomy, and this might be due to the increase in rectal compliance and mean squeeze pressure.","PeriodicalId":77066,"journal":{"name":"Changgeng yi xue za zhi","volume":"22 1","pages":"25-30"},"PeriodicalIF":0.0,"publicationDate":"1999-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21285447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
