Spontaneous migration of a retained bullet is rare. We are presenting here a case of a 24-year-old male with spontaneous migration of bullet from arm to forearm. At the time of initial injury, bullet was left inside the arm as it was deep and patient had no complaints. Three months after injury, he started complaining of pain over forearm and tingling sensations in the forearm and hand over median nerve distribution. Radiographs showed bullet in the proximal forearm. The bullet was than precisely localized and removed under ultrasound guidance. This case report emphasizes the fact that spontaneous migration of bullet in extremities may occur and have the potential to cause neurovascular damage. Removal under ultrasound guidance is a viable option in such locations. 相似文献

BackgroundIdiopathic aortitis (IA) is characterized by giant cell or lymphoplasmacytic inflammation of aorta without a secondary cause.ObjectiveWe undertook a retrospective case–control study to identify characteristic CT angiographic findings in these patients and to correlate them with known atherosclerotic risk factors.MethodsIA cases and controls with noninflammatory aneurysm (control group I) and patients with secondary aortitis (control group II) were identified with a pathology database. Preoperative CT angiographic images of thoracic aorta were reviewed. Diameter of thoracic aorta, wall thickness, and calcification were measured at various sites. Traditional atherosclerotic risk factors were identified from case records and included hypertension, hyperlipidemia, diabetes mellitus, and smoking.ResultsTwenty-two idiopathic aortitis cases were compared with 18 patients in control group I and 16 patients in control group II. No differences were found in prevalence of hypertension and diabetes, but hyperlipidemia was more prevalent in the control group I than in cases (72% vs 36%; P = .03). Current smoking was more prevalent in cases (24%) than for patients in control group I (6%) and group II (19%) but not statistically significant (P = .18 and .69, respectively). Thoracic aortic diameters at various points were significantly larger in cases than for patients in control group I. Calcification was more frequent in cases than for patients in control group II. No differences in wall thickness were found. No meaningful correlation was observed between atherosclerotic risk factors and aortic diameter and calcification scores.ConclusionsPatients with IA have significantly larger and more diffuse dilatation of the thoracic aorta than patients with noninflammatory aneurysms. 相似文献

OBJECTIVES: The results of neonatal surgery in the Western world have rapidly improved over the past three decades. Early nutrition support is thought to be one of the key factors. We used transgastric, transanastomotic feeding jejunostomy tubes in every infant undergoing upper gastrointestinal surgery when the expected period of fasting has exceeded 7 d. METHODS: Newborns with duodenal atresia, malrotation, and jejunal atresia were treated consecutively between November 1998 and November 1999. We analyzed the outcome of such a practice. There were 17 consecutive babies recruited into the study. Ten babies had duodenal atresia, one associated with esophageal atresia and tracheo-esophageal fistula, six had malrotation, and one had jejunal atresia. The weights of the babies varied between 1.2 and 3.78 kg (mean = 2.1 kg) and they were referred between the ages of 1 and 23 d. Three babies were younger than 32 wk of gestation and weighed less than 1.5 kg; all had multiple bowel atresia, including one with associated pyloric atresia. None of these three survived. Enteral feeding was started by postoperative day 2 in 14 cases. Period of feeding varied between 3 and 20 d, with a mean of 10.4 d in the surviving babies. Three of the tubes had minor mechanical complications. RESULTS: The weight loss or gain during the period of hospitalization was not significant (P = 0.3) Breast milk was the most common nutrient. Thirteen of the 14 babies weighing more than 1.5 kg were discharged and are being followed; the remaining baby died from neonatal septicemia. Excellent results can be obtained with aggressive enteral nutrition support in newborns undergoing upper intestinal surgery. CONCLUSIONS: Transgastric, transanastomotic feeding jejunostomy was well tolerated by the newborns and is preferable to parenteral nutrition. 相似文献

OBJECTIVE: To provide a comprehensive, evidence-based review of helium-oxygen gas mixtures (heliox) in the management of pediatric respiratory diseases. Data Source: A thorough, computerized bibliographic search of the preclinical and clinical literature regarding the properties of helium and its application in pediatric respiratory disease states. DATA SYNTHESIS: After an overview of the potential benefits and technical aspects of helium-oxygen gas mixtures, the role of heliox is addressed for asthma, aerosolized medication delivery, upper airway obstruction, postextubation stridor, croup, bronchiolitis, and high-frequency ventilation. The available data are objectively classified based on the value of the therapy or intervention as determined by the study design from which the data are obtained. CONCLUSIONS: Heliox administration is most effective during conditions involving density-dependent increases in airway resistance, especially when used early in an acute disease process. Any beneficial effect of heliox should become evident in a relatively short period of time. The medical literature supports the use of heliox to relieve respiratory distress, decrease the work of breathing, and improve gas exchange. No adverse effects of heliox have been reported. However, heliox must be administered with vigilance and continuous monitoring to avoid technical complications. 相似文献

In this era of preventive dentistry, many dental materials used for prevention of dental diseases are available. Since last few decades efforts are being directed towards prevention of dental caries which is one of the major dental diseases tormenting mankind. The main avenues available are plaque control, use of systemic and local fluorides and use of fissure sealants. There are many factors that contribute towards a successful sealant restoration such as properties of enamel, duration of etching, acid used for etching, manipulative variables. However, one of the prime factors governing the efficacy and life expectancy of a sealant is the marginal adaptability. This study was carried out on a total of 40 intact premolar teeth, which were divided in four main groups and subjected to evaluation under Scanning Electron Microscope. The parameters checked were the width and the number of marginal gaps. The results obtained showed that Teethmate had better marginal integrity and favored the use of invasive technique over non-invasive technique. 相似文献

OBJECTIVES: To determine retrospectively, the outcome of vasectomies performed by five urologists over a six year period in terms of achievement of azoospermia on post vasectomy semen analysis (PVSA) and to compare the effect of the type of suture material used for ligation of the vas deferens on the vasectomy success. METHODS: Review of PVSA results of 3005 consecutive vasectomies done in a district general hospital between November 1998 and October 2004. Patient records and vasectomy logs were reviewed and data analysed. The main outcome measure was achievement of azoospermia on PVSA. RESULTS: The age distribution of men between the two study groups was similar. Overall compliance to provide at least two semen samples for PVSA was 73.8% and was similar between the two groups. Failure to achieve azoospermia on PVSA was seen in 3.5% men (36/1038) in the chromic catgut group and 10.1% men (110/1088) in the Vicryl group (p < 0.0001). Also, the vasectomy failure rates for individual urologists increased significantly following introduction of Vicryl. CONCLUSIONS: In our study we noticed a three fold increase in failure to achieve azoospermia on PVSA with Vicryl as compared to chromic catgut. This study demonstrates that the type of suture material used for ligation of the vas deferens does affect the vasectomy success. 相似文献
