Anaphylactic Shock Caused by Nonruptured Hydatid Cyst of the Liver   总被引:10,自引:0,他引:10  
Anaphylactic reaction is a known complication of cystic hydatid disease, a parasitic infestation caused by the larval/cyst stage of Echinococcus granulosus that usually happens after trauma or during interventions. Nontraumatic leakage of cyst contents into the blood circulation is an uncommon triggering factor for anaphylaxis, which is rarely reported in available literatures. We describe anaphylaxis in a 47-year-old lady who was admitted for evacuation of hydatid cyst of the liver. Unfortunately, she developed signs and symptoms of anaphylaxis in the ward while waiting for her operation. However, the condition was controlled immediately, and she was taken to the operating theater for surgery. As she had not sustained any trauma in the ward and operative exploration did not reveal any macroscopic rupture, we assumed that her problem must have been caused by nontraumatic spillage of cyst material into circulation. Although the condition is not common, one should bear in mind the possibility of such diagnosis in all patients with Eccinococcous infection who develop shock especially in areas where this infestation is endemic.  相似文献

Chronic renal failure in Iranian children   总被引:5,自引:5,他引:0  
We investigated chronic renal failure (CRF) in 166 Iranian children (95 boys and 71 girls) from July 1991 to June 1999. The mean age at onset of CRF was 7.9±4.5 years. The most common cause of CRF was congenital urological malformations (78 cases). The second most common cause of CRF was hereditary nephropathy (21%). Glomerular diseases accounted for only 10% of children who later went on to develop renal failure. High rates of cystinosis and primary hyperoxaluria were seen, and these elevated rates could be due to a high prevalence of parental consanguinity. Eighty-six patients required renal replacement therapy, of whom the majority underwent hemodialysis. The prevalence of primary reflux as a cause of CRF was high compared with reports from western countries. Earlier diagnosis and management of urinary tract infections in this group could reduce the prevalence of reflux as a cause of CRF in this population.

BACKGROUND: Restless legs syndrome (RLS) is a common cause of sleep disturbance frequently experienced by hemodialysis patients. It is a neurological movement disorder. Patients with RLS suffer an irresistible urge to move the legs during inactivity with relief by motion and various activities. MATERIALS AND METHODS: We investigated the clinical course of RLS in 30 (12 female and 18 male) hemodialysis patients with mean dialysis duration of 16.8 +/- 14.13 months who underwent kidney transplantation. Patients were given a standardized questionnaire evaluating details of RLS at baseline and twice after kidney transplantation. They were diagnosed to have RLS by International RLS Study Group criteria. Biochemical (serum calcium, phosphate, Na, and K and blood urea and creatinine) and hematological indices (serum iron, hemoglobin) were measured at each time. RESULTS: RLS in hemodialysis patients was significantly reduced by renal transplantation (43.3%; P<.0001). There was a significant association between RLS and lower serum iron (P<.01) and phosphorus (P<.02) after renal transplantation: We did not observe any association between hemoglobin levels, age, sex, dialysis duration, and time after transplantation with RLS. CONCLUSION: Kidney transplantation showed a strong, positive influence on RLS symptoms in hemodialysis patients. Correction of serum phosphate and serum iron (by mechanisms different than its effect on hemoglobin) can affect RLS in kidney transplant patients.  相似文献

Unwanted hairs are a common problem in which different light sources were developed as the treatment of choice. Alexandrite laser, diode laser, and intense pulsed light (IPL) were clinically used for this purpose with long-term scarce comparative results. The objective of the study was to compare the clinical efficacy, complications, and long-term hair reduction of alexandrite laser, diode laser, and IPL. Clinical trials on 232 persons using diode, alexandrite, laser and IPL were conducted. The number of sessions to reach optimal result varied between 3 and 7. Then the side effects were evaluated. Six months after the last session, optimal hair reduction was observed with no significant differences between the light sources, but a hair reduction was found to be higher using the diode laser. Side effects were observed with all light sources but more frequently with diode. Our findings indicate that all three light sources tested have similar effects on hair removal and in Iranian patients, using lower wavelengths minimizes the side effects.  相似文献

Prognostic factors in survival of colorectal cancer patients after surgery   总被引:2,自引:0,他引:2  
Objective  To determine the factors affecting survival, following resection of large bowel for colorectal carcinoma.
Method  From the cancer database of a single referral institution, a total of 1090 patients who had undergone colorectal resection between 1999 and 2002 were identified. Cases with recurrent colorectal cancer or previous history of neoadjuvant chemotherapy were excluded. Survival curves were plotted using the Kaplan–Meier method. Univariate analysis of factors thought to influence survival was then made using Logrank test. Criteria studied consisted of age, sex, TNM stage, T-status, nodal status, distant metastasis, histological grade, lymphatic and vascular invasion, tumour location, preoperative carcinoembryonic antigen (CEA) level and liver function tests. Multivariate analysis was conducted using Cox regression analysis.
Results  The mean survival time for all patients was 42.8 (SEM = 2.8) months. The overall 1-, 3- and 5-year survival rates were 72%, 54% and 47%, respectively. In univariate analysis, patients' age ( P  < 0.0001), TNM stage ( P  < 0.0001), T-status ( P  = 0.015), nodal status ( P  = 0.016), distant metastasis ( P  < 0.0001), grade ( P  = 0.005), lymphatic and vascular invasion ( P  < 0.0001) and presurgery CEA level > 5 ng/ml ( P  = 0.021) were found to be predictors that could affect survival. In Cox regression analysis, age ( P  < 0.0001), TNM stage ( P  = 0.001) and grade ( P  = 0.008) were determined as independent prognostic factors of survival.
Conclusion  Age, TNM stage, T-status, nodal status, distant metastasis, grade, lymphatic and vascular invasion and presurgery CEA level can predict the postsurgical survival rate in patients with colorectal cancer.  相似文献

Thoracic injury: a review of 276 cases   总被引:2,自引:0,他引:2  
OBJECTIVE: Chest injury, one of the most important aspects of trauma, directly accounts for 25% of all trauma-related deaths and plays a major contributing role in another 25% of trauma deaths. This paper aimed to explore the spectrum and outcome of thoracic injuries seen in a multi centric study of trauma patients. METHODS: A total of 276 consecutive trauma patients in 6 general hospitals were analyzed. The feature of injury, injury severity score (ISS), clinical treatment and mortality were recorded in a prospective manner and analyzed retrospectively. Multiple logistic regression analysis was used to determine the independent predictors of mortality following the chest trauma. RESULTS: There were 246 males (89.1%) and 30 females (10.9%) ranging from 3 to 80 years with a mean age of (34+/-17) years. Road traffic accident was the main cause of injury, especially for pedestrians, followed by stab wound (89 cases, 32.1%) and falling injuries (32 cases, 11.6%), respectively. Haemothorax or pneumothorax (50.4%) and rib fracture (38.6%) were the most common types of chest injury. Extremity fracture was the most common associated injury with the rate of 37% ( 85/230), followed by head injury (25.2%) and abdominal trauma (19.6%). These injuries contributed significantly to the morbidity and mortality of trauma patients. CONCLUSIONS: According to the results, most patients with chest injury can be treated conservatively with close observation and tube thoracostomy. The presence of blunt trauma, head injury and abdominal injury independently adversely affect mortality after chest trauma. It is necessary to investigate the causes and patterns of injuries resulting from stab wound for effective prevention.  相似文献

尼古丁的抗生育效应   总被引:1,自引:1,他引:8  
近年来人类精子质量和生育能力正在下降,提示精子质量的恶化可能部分地归因于环境中毒物效应的增加。不孕不育仍然是一个重要的社会问题,最近的数据显示每4对夫妇中约有1对面临这样的问题。男性不育约占不孕不育的40%。例如,烟草中的烟尘和尼古丁等环境因子以及遗传因子均与精子功能的削弱及其所致的不育相关。本文评述了尼古丁对人类生育能力的影响。根据我们的研究结果,尼古丁被证明是一种像精子这样的生物样本的助氧化剂,它能够通过诱导膜的损伤、干扰GSH代谢循环、改变精子形态和活率、诱导DNA断裂等途径来改变男性的生育能力。补充抗氧化剂可部分地逆转尼古丁对精子功能的副作用。然而,尼古丁影响人类精子功能的具体机制仍需要进一步的研究阐明。  相似文献

Background Controversy continues concerning the morbidity and mortality of HIV-infected ESRD patients on the two dialysis options. This article presents our experience with complications and survival rate among our HIV-infected ESRD patients on peritoneal dialysis and hemodialysis. We reviewed the literature on this subject. Methods The charts of seven and eight HIV-infected ESRD patients on peritoneal dialysis and hemodialysis respectively, between January 1989 and November 2004, were reviewed retrospectively for specific clinical and demographic data. Their survival was calculated using the Kaplan-Meier method. Results Total follow-up of HIV-infected PD and HD patients was 248.3 and 207 patient months, respectively. There was no significant difference in hospitalization rate between HIV-infected PD and HD patients (1.01 and 1.39 admission/year, respectively, P = NS). Survival of HIV-infected patients on PD at one, two and three years was 100, 83, and 50%, and for HD patients was 75, 33, and 33%, respectively. HIV-infected patients on HD had more prevalent advanced HIV disease. Two out of seven PD patients were on PD for more than five years and one of the HD patients was on that form of dialysis for more than nine years. Median survival of patients with advanced (Stage IV) AIDS (both HD and PD) was 15.1 months (range 1.6–17.3) while this value for non-advanced (Stage II, III) patients was 61.2 months (range 6.8–116.6). Conclusion Type of renal replacement therapy does not have a significant effect on the morbidity and mortality of HIV-infected ESRD patients. Survival is worse in patients with advanced HIV disease. Both dialysis options provide similar results in HIV patients; hence, the choice of dialysis modality should be based on patient’s preference and social conditions.  相似文献

Background  

Epithelial-mesenchymal transition has recently attracted great attention in studying the malignant progression of cells through a converging pathway of oncogenesis and metastasis. Twist1 and Mastermind-like 1 (MAML1) are major regulators of EMT through different pathways. The aim of this study was to investigate the clinicopathological relevance of the expression of MAML-1 and Twist1 genes in esophageal squamous cell carcinoma (ESCC).  相似文献
