Barriers to working with impaired trainees: A resident's viewpoint

Psychiatric trainees and educators alike know that significant impairment may occur during training. Although psychiatry programs can do much to identify, treat, and prevent trainee impairment, barriers that may hinder programs from adequately addressing the problems of the impaired trainee continue to exist. These barriers include stigmatization and rejection of the impaired trainee, lack of focus on primary prevention, problematic supervisor-resident relationships, and trainee resistance to intervention. An atmosphere of candor and support, impairment-related seminars, and informed and alert supervisors can be helpful in easing the stress of training and reducing trainee impairment.     

First-trimester screening for trisomy-21 using a simplified method to assess the presence or absence of the fetal nasal bone

OBJECTIVE: To determine the benefit of including nasal bone assessment in addition to standard first-trimester markers (nuchal translucency, free beta human chorionic gonadotropin and pregnancy-associated plasma protein A) as a screening test for Down syndrome, using a strict criterion for classification of nasal bone absence. STUDY DESIGN: Nasal bone assessment was conducted in 2411 patients with crown-rump length between 45 and 84 mm, including 15 patients with Down syndrome. A patient was considered to have an absent nasal bone only if there was no evidence of present nasal bone. Unlike other studies, nasal bone was classified as present when there was evidence of a thin echogenic line under the skin. Simulation studies were conducted to assess the detection rate and false-positive rate of a combined first-trimester screening protocol including nasal bone assessment. RESULTS: There were 9 of 2396 (0.4%) unaffected cases with absent nasal bone (95% confidence interval 0.2%, 0.7%) and 8 of 15 (53.3%) Down syndrome cases (95% confidence interval 26.6%, 78.7%). Using a 1 in 250 risk cut-off, the detection rate of standard first-trimester screening was 87%, with a false-positive rate of 4.3%. Incorporating nasal bone measurement improved the detection rate of Down syndrome to 90% and reduced the false-positive rate to 2.5%. CONCLUSION: The use of a strict criterion to determine nasal bone absence leads to fewer cases classified as absent and may simplify the implementation of nasal bone as a marker for first-trimester screening, resulting in lower false-positives and higher detection, compared with other current screening protocols.     

Morbid Obesity and Gastric Bypass Surgery: Biochemical Profile

Background: Morbid obesity (MO) and the pathologies associated with it constitute an important public health problem, accounting for 7% of the health expenditure in industrialized countries. An important percentage of this expense is attributed to the different biochemical tests performed in these patients, who suffer from several metabolic derangements. We evaluated the basic biochemical abnormalities in MO patients and their reversibility by weight loss after gastric bypass, to standardize the surveillance of the different metabolic abnormalities in obese patients. Methods: By a retrospective analysis on 125 patients operated in our hospital, we evaluated anthropometric and biochemical data before and 1, 3, 6, 12 and 24 months after gastric bypass. Results: Preoperatively hyperinsulinemia, hyperglycemia, dyslipidemia and hypertensive disease were present, and began to improve 1 and 3 months after surgery (although not significantly) and significantly at 6, 12 and 24 months after it. We also observed deficient protein nutrition and a deficiency of micronutrients both before bypass and during the follow-up. Conclusion: After gastric bypass, a marked decrease in insulin occurred, with normalization of blood pressure and the biochemical parameters associated with the metabolic syndrome. We propose a biochemical follow-up protocol for MO patients.     

Applications of the Double O to Z Flap Repair for Facial Reconstruction

Multiple defects are often encountered in the treatment of malignant skin tumors. Nearby defects can present a reconstructive challenge since the closure of one defect may impact the closure of the other defect. The double O to Z flap design is ideally suited to combine the closure of adjacent defects into one technique. This flap technique and design is illustrated and described. Examples include defects on the forehead, temple, cheek, and nose following Mohs micrographic surgery.
