Rhinocerebral mucormycosis (RCM) is a rare, fulminant fungal infection that usually occurs in diabetic or immunocompromised patients. The mortality rate has been reduced recently with the advent of amphotericin B combined with aggressive surgery. Eleven RCM patients have been treated over the past five years at Srinagarind Hospital. Eight had underlying diabetes, five had renal failure and three of them had both. In eight patients, the diagnosis was established by KOH preparation before histological confirmation. Only two cases revealed positive cultures for Rhizopus spp and Cunninghamella spp. All patients underwent surgical treatments (extensive debridement, 8 cases; sphenoidectomy, 7 cases; ethmoidectomy 8 cases; maxillectomy 5 cases and orbital exenteration, 6 cases). Amphotericin B was administered to all patients as soon as the diagnosis of RCM was made. Only three patients survived. Early diagnosis and cooperation among ophthalmologist, otolaryngologist and physician are the most important factors for the survival of patients with mucormycosis. 相似文献

Profiles of HIV voluntary counseling and testing of clients at a district hospital,Chiang Mai Province,northern Thailand,from 1995 to 1999 总被引:3,自引:0,他引:3
Kawichai S Celentano DD Chaifongsri R Nelson KE Srithanaviboonchai K Natpratan C Byerer C Khamboonruang C Tantipiwatanaskul P 《Journal of acquired immune deficiency syndromes (1999)》2002,30(5):493-502
Voluntary HIV counseling and testing (VCT) is a central component of comprehensive HIV prevention strategies targeting individual risk reduction. VCT data are essential for planning and improving HIV/AIDS intervention strategies. The objective of this study is to describe demographic profiles, reasons for seeking HIV counseling and testing, rate of declining HIV testing after pretest counseling, rate of failure to return for HIV test results, and HIV prevalence and associations among 3570 clients who sought VCT at Sansai Hospital in northern Thailand from 1995 to 1999. Data were abstracted retrospectively from client-level data recorded by the hospital counselors on a standard form. HIV prevalence was 29% and remained high throughout the study period. Reasons for seeking VCT for men and women were markedly different and highly correlated with rates of declining the test, failure to return for test results, and HIV prevalence. Declining VCT and failing to return were high among uneducated clients (p <.001). Failure to return among men was associated with HIV prevalence (OR = 1.72, p =.003), particularly for those who had risk behaviors (OR = 5.92, p <.001) and those who wanted to know their HIV serostatus (OR = 4.44, p =.002). Overall, VCT acceptance and returning for test results were high. VCT services at the community level can reach high-risk individuals, especially male partners of women tested as part of routine prenatal care. 相似文献

Quality of life among people living with HIV/AIDS in northern Thailand: MOS-HIV Health Survey 总被引:2,自引:0,他引:2
OBJECTIVES: Translation and psychometric evaluation of a Thai version of the Medical Outcomes Study HIV Health Survey (MOS-HIV) in Thailand. METHODS: A cross-sectional survey in Chiang Mai province, northern Thailand, with data collected in face-to-face interviews using a structured questionnaire designed to measure 10 scales of quality of life (QOL). We recruited 200 people with HIV/AIDS attending self-help groups in the municipal area. Standard guidelines were followed for questionnaire translation and psychometric evaluations. RESULTS: Item-level internal consistency and discriminant validity were reasonably established. Success rates were 93.8 and 97.4%, respectively. Scale-level internal consistency reliability of multi-item scales was satisfactory, ranging from 0.74 to 0.88, with all exceeding inter-scale correlations. Principal components analysis of item and scale scores identified two hypothesized dimensions of the MOS-HIV. The mental health component was strongly loaded by health distress, mental health, vitality and cognitive function scales, and physical health by role, physical and social functions, and pain scales. Respondents manifesting symptoms or reporting worsening health status scored significantly lower on all scales. CONCLUSIONS: These preliminary studies have shown the Thai version of the MOS-HIV to have psychometric properties comparable with those reported in previous surveys. Further testing and modification should make it useful as an HIV-specific QOL measure in Thailand. 相似文献

AIM: To determine allelic imbalance on chromosomal region 21q22-qter including trefoil factor family genes (TFF) in cholangiocarcinoma (CCA) patients and analyze the correlation between allelic imbalances and clinicopathological parameters.METHODS: Quantitative PCR amplification was performed on four microsatellite markers and trefoil factor family genes (TFF1, TFF2, and TFF3) using a standard curve and SYBR Green Ⅰ dye method. The relative copy number was determined by DNA copy number of tested locus to reference locus. The relative copy number was interpreted as deletion or amplification by comparison with normal reference range. Associations between allelic imbalance and clinicopathological parameters of CCA patients were evaluated by x2-tests.Kaplan-Meier method was used to analyze survival.RESULTS: The frequencies of amplification at D21S1890,D21S1893, and TFF3 were 32.5%, 30.0%, and 28.7%,respectively. Patients who had amplification at regions covering D21S1893, D21S1890, and TFF showed poor prognosis, whereas patients who had deletion showed favorable prognosis (mean: 51.7 wk vs 124.82 wk,P = 0.012). Multivariate Cox regression analysis revealed that amplification of D21S1893, D21S1890 and TFF,blood vessel invasion, and staging were associated with poor prognosis.CONCLUSION: D21S1893-D21S1890 region may harbor candidate genes especially TFF and serine protease family, which might be involved in tumor invasion and metastasis contributing to poor survival. The amplification in this region may be used as a prognostic marker in the treatment of CCA patients. 相似文献

Several factors are known to be associated with risk of cholangiocarcinoma (CCA) and infection with the liver flukes, Opisthorchis viverrini and Clonorchis sinensis, has often been singled out as the leading risk factor in east and southeast Asia. In this review, current knowledge of their biology, life cycle, and pathogenesis of O. viverrini, and its role as a carcinogenic parasite are presented. The trends of age‐specific incidence of liver cancer in Khon Kaen, northeast Thailand are considered and compared with the prevalence profiles of O. viverrini. Potential impacts of the liver fluke control program particularly by mass drug administration (MDA) and public health education in the past and a recent drop of incidence of CCA are discussed in relation to primary prevention and control of this fatal bile duct cancer. 相似文献

The human liver fluke Opisthorchis viverrini infection and N‐nitrosodimethylamine (NDMA) administration induce cholangiocarcinoma (CCA) and liver injury in hamsters. Melatonin protects against liver injury and reduces the alteration of mitochondrial structure, mitochondrial membrane potential, and mitochondrial pro‐ and anti‐apoptotic pathways in various cancer types. To investigate the chemopreventive effect of melatonin on CCA genesis and liver injury, hamsters were treated with a combination of O. viverrini infection and NDMA concurrently administered with melatonin (10 mg/kg and 50 mg/kg) for 120 days. Melatonin treatment at 50 mg/kg caused a significant reduction in liver/body weight ratios and decreased tumor volumes leading to an increase in the survival of animals. In the tumorous tissues, the high‐dose melatonin reduced DNA fragmentation and mitochondrial apoptosis by inducing anti‐apoptotic protein (Bcl‐2) in the mitochondrial fraction and down‐regulating cytochrome c, pro‐apoptotic protein (Bax), and caspase‐3 in tumor cytosol. Moreover, a high‐dose melatonin treatment significantly increased mitochondrial antioxidant enzymes and prevented mitochondrial ultrastructure changes in the tumor. Overall, melatonin has potent chemopreventive effects in inhibiting CCA genesis and also reduces liver injury in hamster CCA, which, in part, might involve in the suppression of CCA by reducing tumor mitochondria alteration. 相似文献

Administration of hepatocardnogenic nitrosamines before or afterinfection with the liver fluke, Opisthorchis viverrini (OV),results in marked development of cholangiocellular and hepatocellularprecancerous and cancerous lesions in the hamster liver. Thepromoting effects of OV are believed to be exerted either mechanically,chemically or immuno-logically. To test the influence of possiblemechanical effects, Syrian hamsters were initiated with a singlei.p. injection of dimethylnitrosamine (DMN) 20 mg/kg and subjected2 weeks later either to a sham operation or to complete ligationof the extrahepatic bile duct to the left lateral lobe. At theend of week 40, the animals receiving DMN-initiation and ligationhad a 60.9% incidence of cholangiofibrosis, 21.7% of mucouscystadenomas and 39.1% of cholangiocarcinomas, whereas the groupgiven DMN alone only developed cholangiofibrosis, limited to5% of the animals. In the latter case neither cystadenomas norcholangiocarcinomas were observed. The incidence of hepatocellularnodules did not differ between the two groups and no tumorouslesions developed in either the ligated or the untreated groupswithout DMN pretreatment. Complete ligation of the bile ductitself led to a series of events; obstruction of bile flow beingfollowed by dilatation, cyst formation, and necrosis of thebile duct epithelium and surrounding affected areas leadingto regenerative proliferation. The results are in line withthe conclusion that parasite-associated proliferation in targetcell populations is, at least in part, responsible for the influenceof OV on liver tumor development. 相似文献

BACKGROUND: Chronic subclinical hyperthyroidism induced by suppressive doses of L-thyroxine (L-T4) therapy, so-called exogenous subclinical hyperthyroidism, may cause diminished bone mass in postmenopausal women. The effect of subclinical hyperthyroidism during childhood and adolescence on peak bone mass, however, has not been evaluated. OBJECTIVE: To determine whether exogenous subclinical hyperthyroidism during adolescence, the period of critical bone mass acquisition, would reduce peak bone mass. PATIENTS AND METHODS: Eighteen female adolescents and young adults with Hashimoto's thyroiditis and euthyroid goiter (aged 22.4 +/- 4.4 years) who had been treated with suppressive doses of L-T4, 127.5 +/- 23.7 microg/day, during adolescence (age at onset of subclinical hyperthyroidism, 14.2 +/- 1.5 years) for 6.3 +/- 3.4 years were enrolled in the study. Twenty-nine healthy female volunteers matched for age, weight, height and body mass index served as the controls. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry. Results: BMD of the lumbar spine, radius, Ward's triangle and total body were comparable in the two groups. In contrast, BMD of the femoral neck, trochanter and shaft of patients was slightly higher than those of controls. There were no correlations between BMD values and clinical parameters. CONCLUSION: Exogenous subclinical hyperthyroidism during adolescence has no demonstrable detrimental effect on peak bone mass attainment. 相似文献

PURPOSE: Intracavitary brachytherapy plays an important role in the treatment of cervical carcinoma. Previous results have shown controversy between the effect of dose rate on tumor control and the occurrence of complications. We performed a prospective randomized clinical trial to compare the clinical outcomes between low-dose-rate (LDR) and high-dose-rate (HDR) intracavitary brachytherapy for treatment of invasive uterine cervical carcinoma. METHODS AND MATERIALS: A total of 237 patients with previously untreated invasive carcinoma of the uterine cervix treated at King Chulalongkorn Memorial Hospital were randomized between June 1995 and December 2001. Excluding ineligible, incomplete treatment, and incomplete data patients, 109 and 112 patients were in the LDR and HDR groups, respectively. All patients were treated with external beam radiotherapy and LDR or HDR intracavitary brachytherapy using the Chulalongkorn treatment schedule. RESULTS: The median follow-up for the LDR and HDR groups was 40.2 and 37.2 months, respectively. The actuarial 3-year overall and relapse-free survival rate for all patients was 69.6% and 70%, respectively. The 3-year overall survival rate in the LDR and HDR groups was 70.9% and 68.4% (p = 0.75) and the 3-year pelvic control rate was 89.1% and 86.4% (p = 0.51), respectively. The 3-year relapse-free survival rate in both groups was 69.9% (p = 0.35). Most recurrences were distant metastases, especially in Stage IIB and IIIB patients. Grade 3 and 4 complications were found in 2.8% and 7.1% of the LDR and HDR groups (p = 0.23). CONCLUSION: Comparable outcomes were demonstrated between LDR and HDR intracavitary brachytherapy. Concerning patient convenience, the lower number of medical personnel needed, and decreased radiation to health care workers, HDR intracavitary brachytherapy is an alternative to conventional LDR brachytherapy. The high number of distant failure suggests that other modalities such as systemic concurrent or adjuvant chemotherapy might lower this high recurrence, especially in Stage IIB and IIIB. 相似文献
