Abstract Background. Controversy surrounds the safety and practicality of the retrograde percutaneous translaryngeal tracheostomy (Fantoni procedure) compared with other percutaneous methods. Methods. We used the Fantoni tracheostomy for 245 patients in our intensive care unit (ICU) over a period of 3 years 6 months and conducted a prospective analysis. Results. We are able to report a low incidence of complications (1.2%) with the Fantoni procedure. Advantages of the method are reduced tissue trauma and optimal adaptation of the stoma to the cannula, leading to less stomal bleeding and fewer infectious complications. We observed no procedure-related mortality. Under mandatory bronchoscopic control, proper puncture location and cannula placement are ensured, which prevents tracheal wall injury and paratracheal placement of the cannula. Conclusions. Our experience shows that the major advantage of the use of the Fantoni tracheostomy is the retrograde dilatation of the stoma, which prevents serious complications compared with other techniques. © 2005 Wiley Periodicals, Inc.

Randomized Comparison Between Open Irrigation Technology and Intracardiac-Echo-Guided Energy Delivery for Pulmonary Vein Antrum Isolation: Procedural Parameters, Outcomes, and the Effect on Esophageal Injury

Introduction: We performed a prospective study to compare efficacy and safety of both open irrigation tip (OIT) technology with intracardiac echo (ICE)-guided energy delivery in patients presenting for PVAI. Methods and Results: Fifty-three patients presenting for PVAI were randomized to ablation using an OIT catheter (Group 1, 26 patients; temperature and power were set at 50° and 50 W, respectively, with a saline pump flow rate of 30 mL/min) or radiofrequency (RF) energy delivery under ICE guidance (Group 2, 27 patients; energy was titrated based on microbubbles formation). The mean procedure time and fluoroscopy exposure were lower in Group 1 (164 ± 42 min and 7,560 ± 2,298 ,Graym2 vs 204 ± 47 min and 12,240 ± 4,356 ,Graym2; P = 0.005 and 0.008, respectively). Moreover, the durations of RF lesions applied per PV antrum was lower in Group 1 compared with Group 2 (5.1 ± 2.2 min vs 9.2 ± 3.2 min, P = 0.03, respectively). Within 24 hours after PVAI in 35.7% (all erythema) of Group 1 and 57.1% (21.4% erythema and 35.7% necrosis) of Group 2, patients' esophageal wall changes were documented. After 14 ± 2 months of follow up, recurrences were documented in 19.2% of Group 1 and 22.2% of Group 2 patients. Conclusion: Although both OIT and ICE-guided energy delivery possess a similar effect in treating AF, OIT seems to be superior in terms of achieving isolation and shortening fluoroscopy exposure. Moreover, a lower incidence of esophageal wall injury was observed utilizing OIT for PVAI. [source]

The Rationale for and Comparisons of Different Antiplatelet Treatments in Acute Coronary Syndrome

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2008
PAUL A. GURBEL M.D.
Fundamentally, acute coronary syndromes are platelet-centric diseases, resulting from platelet-rich thrombi that develop at the site of vessel wall injury. In addition to aggregation, platelets modulate a plethora of other important pathophysiologic processes, including inflammation and coagulation. Therefore, a primary goal of therapy in the acute setting should be treatment with agents that provide predictable and superior platelet inhibition to prevent further ischemic events that develop from unchecked high platelet reactivity. Translational research studies of patients undergoing percutaneous revascularization have clearly demonstrated that adverse thrombotic outcomes are associated with high platelet reactivity and the latter is now emerging as a potent measurable cardiovascular risk factor. The intensity of antithrombotic therapy is influenced by patient risk. In the highest risk patients with elevated cardiac biomarkers indicative of myonecrosis, current guidelines support the use of early therapy with glycoprotein IIb/IIIa inhibition, aspirin, and clopidogrel.

Broken ribs: Paleopathological analysis of costal fractures in the human identified skeletal collection from the Museu Bocage, Lisbon, Portugal (late 19th to middle 20th centuries)

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2009

Abstract Although rarely reported in the anthropological literature, rib fractures are commonly found during the analysis of human skeletal remains of past and modern populations. This lack of published data precludes comparison between studies and restricts an accurate understanding either of the mechanisms involved in thoracic injuries or their impact on past societies. The present study aimed: 1) to report rib fracture prevalence in 197 individuals, 109 males, and 88 females, with ages at death ranging from 13 to 88 years old, from the Human Identified Skeletal Collection, Museu Bocage, Portugal (late 19th-middle 20th centuries); 2) to test the hypothesis that a higher prevalence of rib stress fractures existed in the 133 individuals who died from respiratory diseases, in a period before antibiotics. The macroscopic analysis revealed 23.9% (n = 47) of individuals with broken ribs. 2.6% (n = 124) out of 4,726 ribs observed were affected. Males presented more rib fractures, and a significantly higher prevalence was noted for older individuals. Fractures were more frequently unilateral (n = 34), left sided (n = 19) and mainly located on the shaft of ribs from the middle thoracic wall. Nineteen individuals presented adjacent fractured ribs. Individuals who died from pulmonary diseases were not preferentially affected. However, a higher mean rate of fractures was found in those who died from pneumonia, a scenario still common nowadays. Since rib involvement in chest wall injury and its related outcomes are important issues both for paleopathology and forensic anthropology, further investigations are warranted.
