Transesophageal echocardiography (TEE) is used in atrial flutter or fibrillation (AFF) before electric cardioversion to detect intracardiac thrombi. Previous studies have described the use of TEE to diagnose intracardiac thrombi in the left atrium and left atrial appendage, which has an incidence of 8 % among patients without congenital heart disease (CHD). In their practice the authors have noted a significant incidence of intracardiac thrombi in other structures of patients with CHD and AFF. This study aimed to determine the incidence and location of intracardiac thrombi using TEE in patients with CHD requiring electric cardioversion of AFF and to compare the use of TEE and transthoracic echo (TTE) to detect intracardiac thrombus in this population. A retrospective chart review of TEE and TTE findings for all patients with CHD who had electric cardioversion of AFF at our institution from 2005 to 2013 was conducted. The diagnosis, presence, and location of intracardiac thrombus were determined. The TEE and TTE results were compared. The study identified 27 patients with CHD who met the study entry criteria at our institution between 2005 and 2013. Seven of these patients had a single ventricle with Fontan palliation. All the patients presented with AFF and had TEE before electric cardioversion. No patients were excluded from the study. The patients ranged in age from 2 to 72 years (median, 21 years) and weighed 17-100 kg (median, 65 kg). The duration of AFF before TEE and attempted cardioversion ranged from 1 day to 3 weeks (median, 3.5 days). Intracardiac thrombus was present in 18 % (5/27) of the patients and in 57 % (4/7) of the Fontan patients with AFF. No embolic events were reported acutely or during a 6-month follow-up period. Among patients with CHD who present with AFF, a particularly high incidence of intracardiac thrombi is present in the Fontan patients that may be difficult to detect by TTE. Thorough TEE examination of the Fontan and related structures is indicated before electric cardioversion of AFF. The incidence of intracardiac thrombus in CHD patients is more than double that reported in non-CHD patients.

Objective: To assess the attitude and practices of adolescents regarding water-pipe smoking (WPS) in a predefined 'perceived' high risk group of youth 12-18 years of age in the Detroit metropolitan area. Methods: This was a cross-sectional survey (conducted March1 st through June 30 th , 2008) in which participants completed a self-reported questionnaire, which included demographics, WPS, other types of smoking, and their perception about the hazards of WPS. Results: A total of 272 [85% response rate (272/320] surveys were completed. One hundred and sixty seven (61%) were WPS "users". Fifty-six (22%) used WPS at home, 34 (13%) at coffee shops, 74 (29%) at both locations, and 3 (1%) at other locations. Relative to non-users, WPS users were more likely to be cigarette smokers (OR = 1.7, unadjusted OR = 2.5, p < 0.05), to have someone else in the household who uses WPS (OR = 2.2), to believe that WPS is safe (OR = 1.4, unadjusted OR = 2.0) and that WPS is less harmful than cigarettes (OR = 1.2 unadjusted OR = 1.6, p<0.05). In addition WPS use was associated with less likelihood of believing that one may acquire an infection (OR = 0.9) and that the toxicity of the inhalants was equivalent to cigarette smoking (OR = 0.8). Conclusions: WPS represents a growing public health issue for adolescents in the US. Aggressive education of adolescents is essential in combating the misperception associated this form of smoking.

Fine needle aspiration (FNA) in the operating room is a convenient optional diagnostic approach. Our objective of this study was to evaluate the accuracy and study the potential benefits of fine needle aspiration in the operating room. Retrospective review of all intraoperative FNA that were requested and performed by pathologists over 20-month period was carried out. Immediate smears were interpreted by the cytopathology team after staining with Diff Quik stain. All cases were reviewed and correlation with subsequent tissue diagnosis was done. Accuracy was calculated and potential benefits were discussed. The number of aspirates was 32. Adequate material for immediate and final interpretation was achieved in 31 cases (sensitivity 97%). In 20 cases (63%), malignancy was diagnosed while a benign diagnosis was rendered in 12 (37%). All cases had a follow up tissue diagnosis. No false-positive cases were identified (specificity 100%). The information gained from this approach was considered helpful to the surgeons. We concluded that FNA of head and neck masses in the operating room is an accurate and sensitive diagnostic approach. The service provides helpful information to surgeons and is an additional optional diagnostic approach.
