Although the intramedullary nailing is thought to be the method of choice for treatment of closed tibial shaft, there is ongoing debate on the optimal surgical approach in patients with open types of these fractures. In addition, choosing between the reamed and unreamed intramedullary nailing is still an issue for the orthopedic surgeons. In present study, we aimed to compare the outcome and consequences of OA tubular external fixation vs. unreamed intramedullary nailing in open grade IIIA-IIIB tibial shaft fractures. In a randomized clinical trial, 50 patients with open tibial shaft fractures (grades IIIA-IIIB) were recruited in Tabriz Shohada teaching centre in a 2-year period of time. They randomized in two equal groups underwent either AO tubular external fixation or unreamed intramedullary nailing. These 2 groups were matched for sex, age and fracture-grade. The follow-up time was one year. Union time, surgical outcome, postoperative complications and the ambulation time were compared between the two groups. Twenty five patients, 20 males and 5 females with a mean age of 30.80 +/- 5.24 years were allocated in unreamed intramedullary group and 25 other patients, 22 males and 3 females with a mean age of 28.92 +/- 8.88 years were studied in the external fixation group (p = 0.70 and 0.37, respectively). The two groups were matched for sex (p = 0.70) and age (p = 0.37). The time of union was 3, 4, 5 and 6 < or = weeks after operation in 28, 12, 32 and 28% of the cases in unreamed intramedullary group vs. 4, 12, 48 and 36% of the cases in external fixation group, respectively (p = 0.14). Post-operative infection, soft tissue injury, malunion and nonunion were documented in 16, 8, 0 and 4% of the cases in unreamed intramedullary group vs. 32, 12, 24 and 8% of the cases in external fixation group, respectively (p = 0.19, 0.50, 0.02 and 0.50, respectively). The mean ambulation time after operation was 2.92 +/- 2.43 weeks in the unreamed intramedullary nailing group vs. 2.68 +/- 2.14 weeks in the external fixation group (p = 0.71). Our results are in favor of unreamed intramedullary nailing against external fixation in treatment of open tibial shaft fractures. 相似文献

The aim of present study was to determine the prevalence of Human Immunodeficiency Virus (HIV) and Hepatitis B Virus (HBV) infections in preoperative patients admitted for surgical procedures at the Lagos University Teaching Hospital (LUTH), Lagos, Nigeria. Two hundred patients (200 samples tested for HIV) and (100 samples tested for HBV) comprising 90 males (45%) and 110 females (55%) were recruited into the study. Sixty-eight of the 200 patients (34%) were scheduled for emergency surgery (group A) and 132 (66%) listed for elective surgery (group B). Seven (3.5%) of the 200 patients tested positive for HIV-1 and 2 using the Well-coenzyme method. Five (2.5%) and 2 (1%) of the 200 patients confirmed HIV-positive were females and males respectively. Sixty-one percent of the 100 patients tested for hepatitis B surface antigen were males and 39 (39%) females. Eighteen percent of the 100 patients examined were positive for (HbsAg). Ten percent of the 18 HBsAg-positive patients were males and 8 (8%) were females. This study showed the prevalence rate of HIV and Hepatitis B in preoperative patients at the Lagos University Teaching Hospital and to some reflects the prevalence of HIV and HBV in the general population. 相似文献

Distal radius fractures are among the most common bone fractures all over the world. Close reduction and fixation by percutaneous pinning is a less invasive method comparing with other open surgeries. This study aims at evaluating the functional outcome of this treatment in distal radius fractures. In this prospective study, 50 patients with distal radius fractures underwent percutaneous pinning during a 16 month period in Tabriz Shohada Hospital. Follow-up for 3 months was possible in 48 (96%) patients. Possible complications (such as infection, nonunion, pin loosening and pain), functional outcomes (including range of motion, grip and pinch strengths) and radiological outcome were documented in intervals during follow-up. Forty eight patient, 22 males and 27 females with a mean age of 47.1 +/- 13.7 (19-80) years were enrolled. Local pain, infection and pin loosening were documented in 14.6, 16.7 and 2.1% of cases, respectively. Based on radiological reports, unacceptable palmar tilt, articular step, radial inclination and radial shortening were present in 6.3, 0, 2.1 and 6.3% of cases, respectively three months post-operation. The clinical outcomes according to Cooney's modification of the Green and O'Brien scheme were as excellent, good, fair and poor in 52.1, 31.3, 10.4 and 6.3% of cases, respectively. According to these results, closed reduction and percutaneous pinning of distal radius fractures is a rather successful method with minor complications. 相似文献

Echinococcosis is very frequent helminthic infection in human being. The disease is endemic in Iran and particularly in its northwestern region, East Azerbaijan. The objective of this study was to study demographics of patients with cystic echinococcosis in East Azerbaijan; as well as to repot the sites of involvements. In this cross-sectional study, 318 patients with surgical and nonsurgical cystic echinococcosis were recruited from three referral centers in Tabriz within a 10-year period of time. The patients' demographics (age and gender) and the site of infection were investigated. Among the patients, females were predominant (57.5 vs. 42.5%). The mean age of patients was 32.59 +/- 18.47 (range: < 1-87) years and the most frequently age group was 20-30 years (23.6%), followed by the age groups of 30-40 years (21.7%), 10-20 years (14.2%), 40-50 years (11.9%), 50-60 years (11.3%), < 1 year (6%), 60-70 years (4.7%), 1-10 years (4.1%) and finally, > 70 years (2.5%). The lung was the most frequently infected organ (48.1%), followed by the liver (28.9%), gallbladder (3.5%), spleen and kidney (each one in 2.2%), abdomen, intestine, pleura, bronchus and mediastinum (each one in 1.6%), chest wall and heart (each one in 1.3%), brain, pericardium, facial sinus, pancreas and esophagus (each one in 0.6%) and the ovary, uterus, axillary region, pelvis and femur (each one in 0.3%). In conclusion, this study showed that the patients with hydatid cysts in East Azerbaijan Province are mainly females in the age group of 20-40 years. The lung and liver are the major sites of infection in these patients. 相似文献

The Algerian Cubtail (Gomphus lucasii Selys) (Odonata: Gomphidae) is a river-dwelling dragonfly and one of the least known gomphid in the Palearctic. A survey of the movement patterns and habitat requirements of adults was conducted in the largest currently known population, located in the Seybouse River (Northeast Algeria). Daily mark-release-resighting surveys along a 2.5 km stretch of the watercourse and within plots in terrestrial habitats were carried out; a total of 1,316 individuals were marked. The resighting rate along the watercourse was 8.13% and did not significantly vary with sex and age. Adult spatial distribution differed according to sex and age. Mature females were significantly further from the water than males. Mature males were observed not only along the watercourse but also far from the water, up to 450 m where reproductive pairs in copula were recorded. Preferred maturation and foraging sites were open grasslands and dense wheat fields. Philopatry to reproductive sites had a mean of 1.11%, while philopatry to emergence site was lower (0.4%) and noted only in males. The mean distance of natal dispersal (from emergence to reproductive areas) was 596.5 ± 4.94 m. The mean dispersal distance from one reproductive site to another was 180.97 ± 238.54 m. Both mature males and females preferred fast flowing water, but females were observed to oviposit in relatively small watercourses. 相似文献

Erythema Multiforme (EM) is a type of allergic reaction that occurs in response to medications, infections, or different illnesses. In many cases, a definite underlying cause may not be identified. This study aimed to evaluate adult EM outpatients with regard to patients' characteristics, the disease and the underlying contributors. In this cross-sectional study, 61 adult EA outpatients referred to the Dermatology Clinic of Tabriz Sina Hospital were recruited during a 12-month period (January 2009-January 2010). The diagnosis was made based on clinical and morphologic grounds. Age, sex, types of EA, location and type of the lesions and the underlying causes were documents. An infectious etiology was suspected when a preceding illness was noticed without drug ingestion within 1 week prior to the onset of the rash. A drug related to the condition was defined as every drug that has been taken during 21 days prior to the onset of any symptoms. There were 34 males and 27 females with a mean age of 26.8 +/- 15.3 (18-57) years enrolled. The EM was minor in 62.3% and major in 37.7% of patients. The upper limb was involved in all patients. The lesions were maculo-papular, vesiculobullous and bullous in 83.6, 13.1 and 3.3% cases, respectively. Drugs and herpes simplex were the main causes in 49.2 and 16.4% of patients, respectively. The disease was idiopathic in 34.4%. The underlying drugs were sulfonamides in 12 cases (19.7%), penicillin in 5 cases (8.2%), salicylic acid, aspirin, cimetidine and amoxicillin each one in 3 cases (4.9%) and barbiturate in 1 case (1.6%). Five cases (8.2%) were recurrent EM including 4 males and 1 female, 3 idiopathic and 2 cases due to sulfonamides. 相似文献

The wasp Spalangia endius Walker (Hymenoptera: Pteromalidae) is a major parasitoid of the pupae of fruit flies, which are a common agricultural pest. An understanding of this intricate host–parasitoid interaction could provide basic information necessary for the sustainable integrated biological control of fruit flies. In this study, we investigated the effect of S. endius on different-aged pupae of the melon fly Bactrocera cucurbitae Coquillett by using choice and nonchoice tests under laboratory conditions. We showed that S. endius females oviposited, and their progeny successfully developed, in different-aged pupae of B. cucurbitae regardless of the method of exposure. There was an oviposition preference for 3–5-d-old pupa. The highest mean percentage parasitism occurred on 4- and 5-d-old hosts, followed by 2- and 3-d-old hosts. The average development time for both males and females was significantly longer in 6–7-d-old hosts than in the younger host stages. Adult females that developed from younger host pupae (2–5-d old) were significantly heavier than those from older host pupae (6–7-d old), and they also lived longer. The sex ratio (proportion of females) of the parasite progeny decreased with an increase in host age. Host mortality also decreased gradually as the pupal age increased. The differences in development time, body weight, and longevity between females and males were significant. These results suggest that S. endius is a good candidate for the biological control of B. cucurbitae. 相似文献

This study aims at assessing the relation between hypoalbuminemia and inhospital mortality in patients with acute stroke. In this cross-sectional study, a total of 112 consecutively admitted patients with first acute stroke in Ahvaz Jundishapur Hospital were enrolled. All patients hospitalized for 7-9 days or expired in this period of time. Admission hypoalbuminemia (serum albumin < 3.5 mg dL(-) as well as other prognostic factors were determined and compared between the two groups. One hundred and twelve patients, 74 males and 38 females with the mean age of 69.2 +/- 12.1 (66-79) years were enrolled. Twenty nine (25.9%) patients expired during the hospitalization. Totally, admission hypoal buminemia was present in 49 (43.8%) patients. 43% of the patients were Hypoalbuminemia. Frequency of patients with admission hypoalbuminemia and is chemic heart disease was significantly higher in the nonsurvivors (75.8-32.5%, p = 0.001; 34.5 vs. 16.9%, p = 0.047, respectively). The mean Glasgow Coma Scale score was significantly lower in the nonsurvivors (8.1 +/- 1.8 vs. 9.4 +/- 0.5, p = 0.003). These three parameters remained significant in multivariate analysis. Sex, age, history of hypertension, diabetes mellitus, hypertriglyceridemia, hypercholesterolemia, anemia, heart failure and smoking habit, admission atrial fibrillation, ethnicity and stroke type were comparable between the two groups. In conclusion, hypoalbuminemia is an independent predictor of inhospital mortality in patients with acute stroke. 相似文献

There are several methods for the diagnosis and evaluation of coarctation of the aorta. Digital Subtraction Angiography (DSA) is the standard detection method, though it entails complications and side-effects. The aim of the present study was to compare Computed Tomography (CT) angiography with DSA for diagnosing aortic coarctation. We performed a cross-sectional study of 15 patients (11 males and four females aged between two and 30 years) referred to Tabriz Shahid Madani Hospital and Imaging Center between August 2005 and February 2006 with suspected aortic coarctation. All patients were subjected to DSA and CT angiography for diagnosis of aortic coarctation. The mean age of the patients was 14.6 years; 11 were male (74.4%) and four (26.6%) were female. The DSA and CT angiography results were comparable in all patients in terms of diagnosis and the detection of complications, particularly cardiovascular complications. However, CT angiography was less time-consuming to perform than DSA (p < 0.0001). In conclusion, CT angiography, comparableto DSA, diagnosed coarctation of aorta in all the patients. However, CT angiography is a non-invasive, cost effective procedure that takes significantly less time to carry out than DSA. Therefore, CT angiography is recommended as an appropriate method for diagnosing the coarctation of aorta. 相似文献

Prediction of outcome is difficult in patients with acute upper gastrointestinal bleeding (AUGIB). Some factors have been proposed in this regard with varying accuracy. This study aimed to investigate probable predictors of in-hospital outcome in patients with AUGIB. One hundred sixty four patients with AUGIB were studied prospectively in Tabriz Imam Reza Teaching Centre. All these patients were evaluated endoscopically by an expert. Patients' age, gender, presenting complains, transfusion, clinical findings and previous medical history were compared between survived vs. expired, re-bled vs. non re-bled and operated vs. non operated patients. There were 117 males and 47 females with the mean age of 57.12 +/- 17.32 (range: 32-78) years in this study. Hematemesis was the sole independent predictor of in-hospital mortality (82.1 vs. 100%; p < 0.001). In univariate analysis, however, female gender, major hemorrhage and previous neurological disease were associated with higher rate of expiration. Comparing two re-bled and non re-bled groups, hematemesis (76.5 vs. 95.9%; p = 0.003) and need of transfusion > 2U (36.1 vs. 71.4%; p = 0.006) were independent predictors of re-bleeding. In univariate analysis, hematocrit < 30%, major hemorrhage and previous history of hepatic disease or hypertension were predictive of re-bleeding. In comparison between operated and non operated groups no significant predictor was detected. In conclusion, this study showed that presence of hematemesis at the time of admission and need of transfusion > 2U were independent predictors of poor outcome in patients with AUGIB. 相似文献

The effects of four host plants (Agave sisalana, Ag. americana var. marginata, Ananas comosus Baili and An. comosus Smooth Cayenne) on the biology of the mealybug Dysmicoccus neobrevipes Beardsley were studied in the laboratory at 26 ± 1 °C, 75-90% RH and 14:10 (L:D) photoperiod. The development, survivorship, longevity, reproduction and life table parameters of D. neobrevipes differed among the host plants. The shortest developmental period (from the first instar nymph to adult) was recorded on An. comosus Smooth Cayenne (22.4 days for females and 21.3 days for males), whereas the longest was recorded on An. comosus Baili (25.6 days for females and 24.7 days for males). The highest survivorship was found on An. comosus Baili (98% for both females and males) and the lowest was on Ag. americana var. marginata (39.6% for females and 50% for males). Meanwhile the sex ratio and fecundity were highest and the pre-lay period was shortest on Ag. sisalana. The longest longevity of females was 62.5 days on An. comosus Baili, whereas the other host plants did not differ significantly with grand mean longevities of 51.0 days for females, while the longest and shortest longevities of males were 4.6 days and 2.3 days on Ag. americana var. marginata and Ag. sisalana, respectively. Values for net reproductive rate, intrinsic rate of increase and finite rate of increase were highest on Ag. sisalana, whereas the mean generation time was shortest on An. comosus Smooth Cayenne. The results indicated that Ag. sisalana is the most suitable host for D. neobrevipes among the four tested plants. When reared on Ag. sisalana, D. neobrevipes had a short developmental period (females 22.7 days and males 23.8 days), high reproduction (418 nymphs/female) and a high intrinsic rate of increase (0.106). Results of this study indicated that host plant can largely influence the population dynamics of D. neobrevipes, and our findings are useful in understanding the roles of host plants in integrated management of this pest, including exploitation of these host plants in push-pull control. 相似文献

Some studies have shown that catecholamines and the changes in their levels during and after head trauma can be useful in predicting the outcome in head trauma patients. The goal of this study is to search for a probable relation between urine levels of catecholamines and prognosis in patients with severe head trauma. Fifty four patients with severe head trauma Glasgow Coma Scale (GCS < or = 8) on admission time were recruited in Imam Reza Hospital within one. These patients were included when having no major accompanying trauma in other organs. Twenty four hour urine was collected after admission and levels of metanephrine and nor-metanephrine were measured. The relation between urine levels of these metabolites with final outcome and also with GCS at admission, 24, 48 h and 1 week after admission and discharge time and Glasgow Outcome Scale (GOS) were studied. Fifty two patients, 48 males and 4 females with a mean age of 32.3 +/- 14.7 (3-72) years were included. The main underlying etiologies were motorcycle (46.2%) and car accidents (25%). Diffuse axonal injury, brain contusion and subdural hematoma were three main diagnoses (28.8, 17.3 and 15.4% of the cases, respectively). 19 (36.5%) of the patients expired within the study period. The mean level of metanephrine and normetanephrine in urine were 207.9 +/- 200.5 and 330.2 +/- 218.4 microg in 24 h, respectively. There was no meaningful relation between urine levels of these metabolites and any of GCS and GOS. There was also no meaningful relation between these parameters and final prognosis in patients. 相似文献

Background: Iron deficiency anemia is one of the major causes of morbidity and mortality worldwide. Evidences from epidemiological and clinical studies suggest a possible correlation between antioxidant levels and the anemic disease risk. The present work is to investigate antioxidant levels and lipid peroxidation in anemic patients. Methods: A number of 30 patients (15 males and 15 females) were selected for the study. Likewise, 30 age- and gender-matched healthy volunteers (15 males and 15 females) were selected with their informed consent. Patients and healthy subjects were supplemented with vitamins C and E for 15 days. The lipid peroxidation both in plasma and erythrocyte lysates was determined by thiobarbituric acid reactive substances and lipid peroxides. The antioxidant vitamins A, C, and E and total antioxidant activity were also analyzed. The antioxidant enzyme superoxide dismutase, catalase, and glutathione peroxidase were also determined. Results: Based on analysis, we found that the increase in lipid peroxidation was higher in the anemic subjects before vitamin supplementation, which was statistically significant at P<0.05. The antioxidant enzymes were higher in the patients before antioxidant supplementation when compared with patients after vitamin supplementation. Conclusion: Our data revealed higher oxidative stress before vitamin supplementation in iron deficiency anemic patients and after supplementation, lower lipid peroxidation and increased antioxidant vitamins were achieved.

This study was planned to assess the dietary intake of diabetic subjects and kind of dietary modification they have made after individualised dietary guidance. Information on clinical and dietary profile of 200 subjects was recorded at first visit of BIDE. Dietary guidance was given by dietician. Second visit was done after 3 months. Subjects having adequate intake of fruit and vegetable, milk and meat was 68, 38 and 63% for males and 52, 40 and 35% for females, respectively. Only 20.4% males and 5.9% females had usual adequate consumption of the four food groups. Overall adequacy of diet improved for 11.1% of males and 27% of females. Weight reduction was observed in 54.8% of females and 32.2% of males. Rate of BMI reduction was significantly higher in the group who had reduced their caloric intake. This first of its kind study from Pakistan, has documented the efficacy of dietary guidance and highlighted the need for further attention to assure balanced intake of foods form various food groups. 相似文献

The study was aimed to identify the role of virtual bronchoscopy in detection of airway malacia in children. In a pre-experimental study over 3 years (from Nov. 2003 to Oct. 2006), 35 consecutive patients were presented to Tabriz Children's Hospital with clinical manifestations of airway malacia, examined by the technique of virtual bronchoscopy. Thirty five patients including 23 males and 12 females with the mean age of 3.7 +/- 1.6 months were studied. The presence of airway malacia and its location and severity were determined by virtual bronchoscopy in all studied cases; that revealed: laryngomalacia, bronchomalacia, tracheomalacia, laryngotracheomalacia and laryngobronchomalacia in 42.8, 25.7, 20, 8.6 and 2.9% of patients, respectively. Virtual bronchoscopy is a non-invasive, accurate and rapid imaging technique with an excellent validity for diagnosis of airway malacia and stenosis, therefore it can replace conventional bronchoscopy. 相似文献

This study investigated the usage, consumption pattern and chemical composition of fermented foods consumed in 191 rural households (1 030 individuals) in Emene. The result showed that fermented foods were widely used and consumed by most age groups (under 2 years to adults) because of poor socioeconomic status. Fermentation period varied with type of food and was mostly carried out as a means of detoxifying certain foods. Generally, fermented foods contributed substantially to the daily caloric (46.3 to 79.9% for males and 57.5 to 78% for females); calcium (33.8 to 63.5% for males and 48.3 to 55.4% for females); iron (34.4 to 58.6% for males and 47.4 to 74.6% for females); and thiamin (23 to 58.5% for males and 37.5 to 60% for females) intakes. The contributions of fermented foods to protein (10 to 40.7%) and ascorbic acid (1.9 to 18.7%) intakes were however, low. When compared with the FAO recommendations, the daily intakes of protein, calcium, riboflavin, niacin and ascorbic acid by the subjects were low due to large consumption of starchy root crops. Poor financial status was the most limiting factor to adequate nutrient intake. Such results point out the need for nutrition education related to improved methods of preparation and food selection. 相似文献
