Various examples of foreign body embolization of cerebral arteries, usually followed by serious consequences, have been reported (Lindberg et al., 1961; Chason et al., 1963; Steele et al., 1972; Wetli et al., 1972). However, a shotgun pellet entering the left atrium of the heart through a gunshot wound of the chest with subsequent embolic occlusion of one of the carotid arteries appears to be unique. It is the subject of this short communication. 相似文献

Epistaxsis and crustation are common problems associated with long-term use of oxygen through nasal prongs in patients suffering from chronic obstructive pulmonary disease. The nasal prong can cause direct trauma to the septal mucosa. We describe a simple solution to this problem with use of the disposable ear tip used in tympanometry. 相似文献

Experimental evidence from animal models has provided a framework for our current understanding of autoimmune disease pathogenesis and supports the importance of genetic predisposition, molecular mimicry, and immune dysregulation. However, only recently has evidence emerged to support the role of immune dysregulation in human organ-specific autoimmune disease. In the current study of the "late" manifestation of autoimmune thyroid disease (AITD) in a cohort of human immunodeficiency virus (HIV)-positive patients following highly active antiretroviral therapy (HAART), we discuss how immune dysregulation and factors associated with the immunopathology of HIV infection fit the current understanding of autoimmunity and provide a plausible basis for our clinical observations. De novo diagnoses of thyroid disease were identified between 1996 and 2002 in 7 HIV treatment centers (5/7 centers completed the study). Patients were diagnosed as clinical case entities and not discovered through thyroid function test screening. Paired plasma specimens were used to demonstrate sequential rise in thyroid antibodies.Seventeen patients were diagnosed with AITD (median age, 38 yr; 65% were of black African or black Caribbean ethnicity; and 82% were female). The median duration of immune reconstitution was 17 months. Graves disease (GD) was diagnosed in 15 of 17 patients. One patient developed hashithyrotoxicosis with atypically raised C-reactive protein, and another developed hypothyroidism. One GD patient had associated secondary hypoadrenalism. The estimated combined prevalence of GD for 4 treatment centers for female patients was 7/234 and for males was 2/1289. The denominator numbers were matched controls, from 4 centers able to provide data, who commenced HAART during the same time (January 1996 to July 2002) and who did not develop clinical AITD. The mean baseline pre-HAART CD4 count was 67 cells/mL, and the mean increase from nadir to AITD presentation was 355 cells/mL. AITD patients were more likely than controls (95% confidence interval, chi-square test) to be severely compromised at baseline (as defined by a CD4 count < 200 cells/mL or the presence of an acquired immunodeficiency syndrome [AIDS]-defining diagnosis), and to experience greater CD4 increments following HAART. AITD may be a late manifestation of immune reconstitution in HIV-positive patients taking HAART, and immune dysregulation may be an important factor. 相似文献

Objective: The present study was conducted in year 2002 in NCT of Delhi with the objective to re-assess the prevalence of iodine deficiency
disorders.Methods : A total of 7009 children in the age group of 6–11 years were clinically examined for presence of goiter. A total of 991
salt samples were also collected randomly. On the spot casual urine samples were collected from 1395 children.Results : The total goiter prevalence was found to be 6.2 %. The percentage of children with urinary iodine excretion (UIE) of <20.0,
20.0-<50.0, 50.0–99.9 and 100.0 Μg/l and above was 0.8, 1.8, 8.7 and 88.7%, respectively. The median UIE level was 200 Μg/L
The assessment of iodine content of salt revealed that only 16% of the families were consuming salt with iodine content less
than 5 ppm.Conclusion : The findings of the present study indicated that the population is in a transition phase from iodine deficient (as revealed
by Total Goiter Prevalence) to iodine sufficient nutriture (as revealed by median UIE 200 Μg/l). A significant progress has
been achieved towards elimination of IDD from NCT of Delhi. 相似文献

An 11-year-old girl with an almond lodging in the tracheobronchial tree is described. She presented with an uncommon symptom of subcutaneous emphysema The x-ray revealed left-sided pneumothorax and pneumomediastinum. Intercostal drain was inserted, but she developed respiratory failure and was ventilated. After initial stabilization for 60 hours, she deteriorated again and her x-ray revealed right-sided collapse. After removal of the foreign body, she was discharged but presented again with stridor necessitating tracheostomy. Tracheal stenosis was found and required end-to-end anastomosis. The authors feel that, while foreign bodies are uncommon in this age group with emphysema as a rarer manifestation, this cause should be kept in mind, even in the absence of forthcoming history. A high index of suspicion for tracheobronchial foreign body is required in atypical presentations of acute pediatric respiratory distress. 相似文献

Overuse injuries: tendinopathies, stress fractures, compartment syndrome, and shin splints 总被引:1,自引:0,他引:1
Approximately 50% of all sports injuries are secondary to overuse and result from repetitive microtrauma that causes local tissue damage. Injuries are most likely with changes in mode, intensity, or duration of training and can accumulate before symptoms appear. Intrinsic factors contributing to injuries are individual bio-mechanical abnormalities such as malalignments, muscle imbalance, inflexibility, weakness, and instability. Contributing extrinsic (avoidable) factors include poor technique, improper equipment, and improper changes in duration or frequency of activity. Injuries are often related to biomechanical abnormalities removed from the specific injury site, requiring evaluation of the entire kinetic chain. This article discusses common overuse injuries of the lower leg, ankle, and foot: tendinopathies, stress fractures, chronic exertional compartment syndrome, and shin splints. 相似文献
