The effects of an intensive lifestyle modification program on sleep and stress disorders.

BACKGROUND: To determine if a lifestyle change program can modify behavior to reduce sleep and stress disorders. METHODS: Analyses are based on 2,624 individuals aged 30 to 80 years from the Rockford, Illinois metropolitan area who completed a lifestyle evaluation at baseline and again after four weeks, following participation in a 40-hour educational course given over a four-week period. Participants receive instruction on the importance of making better lifestyle choices related to making long-term improvements in nutrition and physical activity and they learn ways to improve sleep and reduce stress in their lives. RESULTS: Significant percent decreases were observed in the number experiencing selected sleep or stress disorders from baseline to four weeks later for "sleeps restlessly" (-59%), "suffers from insomnia" (-64%), "feels under pressure" (-37%), "easily emotionally upset" (-52%), and "feels fearful or depressed" (-61%). Experiencing a selected sleep or stress disorder after four weeks among those who had the disorder at baseline was significantly more likely in those not physically active and/or not having lowered their BMI after four weeks. Changes in alcohol consumption and smoking did not significantly contribute to changes in the disorders. Those who failed to lower their coffee/tea use after four weeks were significantly more likely to have a sleep disorder and be easily emotionally upset. CONCLUSIONS: Changes in lifestyle behaviors after attending an educational program significantly reduced sleep and stress disorders in as little as four weeks, primarily explained by decreasing BMI and/or increasing exercise.

A supervised training program in flexible sigmoidoscopy: evaluating skills from residency training to clinical practice.

To assess the effectiveness of a training program in flexible sigmoidoscopy for family practice residents, we prospectively studied the performance of four residents during their training and after graduation. One hundred and four training exams performed with the assistance of an experienced gastroenterologist were compared with 118 unassisted post-training, post-residency exams. The mean depth of insertion for the post-training period was 51.1 +/- 1.2 cm, which was significantly greater (P less than .05, Student's t test) than the mean training period depth of 47.6 +/- 1.2 cm. There was no significant difference in the identification of polyps or cancer between the training and post-training periods. The mean duration of an exam was 17.3 +/- 0.6 minutes in the post-training period. No significant complications were encountered in either period. The residency trained family physicians obtained results similar to those reported by trained endoscopists in depth of examination and pathology detected, although their examinations required more time. We conclude that this model of training was effective in the development of flexible sigmoidoscopy procedural skill for family practice residents.

Cystadenoma of the liver.

We report a patient with cystadenoma of the liver who presented with jaundice and abdominal mass. Although cystadenoma of the liver is a rare neoplasm, the lesion was diagnosed preoperatively by gray scale ultrasonography, PTC and ERCP. Characteristically, cystadenoma shows a multiseptated cystic appearance. While the origin of a cystadenoma is unclear, theories of synchronous development from anomalous bile ducts, endodermal diverticula, and ectopic germ cell origins have been promoted. Approximately 85% of patients with hepatic cystadenoma are women, with an insidious onset of symptoms due to the slowly growing nature of this tumor. Common symptoms include right upper quadrant mass, abdominal distension, and dull abdominal pain. Jaundice is less common. Complications include biliary obstruction, infection, hemorrhage, and rupture. As hepatic cystadenoma tends to recur after inadequate excision, and has malignant transformation potential, hepatic lobectomy has been promoted as definitive treatment.
