Cardiovascular Rehabilitation Increases Walking Distance in Patients With Intermittent Claudication. Results of the CIPIC Rehab Study: A Randomised Controlled Trial.

OBJECTIVE: To examine whether a cardiac rehabilitation programme in a community based setting for patients with intermittent claudication (IC) affects walking ability, quality of life, and changes in health behaviour. The trial investigated a cross sector cardiovascular rehabilitation programme compared with usual care for patients having non-operative management. METHODS: The trial allocated 118 patients, with 1:1 individual randomisation to either an intervention or control group. Data were collected at a department of vascular surgery and at a healthcare centre in Denmark. The rehabilitation intervention consisted of usual care plus 12 weeks of exercise training, pedometer, health education, and text messages. The primary outcome was maximum walking distance at six months measured by treadmill walking test. The secondary outcomes were maximum walking distance at 12 months and pain free walking distance measured by treadmill walking test, healthy diet, level of physical activity, and quality of life (QoL) at six and 12 months. RESULTS: In the intervention group, 46 participants were analysed, with 47 in the control group. Following three months of rehabilitation, a 37% difference (95% CI 1.10 - 1.70; p = .005) was found between groups in maximum walking distance at six and 12 months, in favour of the intervention group. The same positive effect was found in physical activity, QoL, and healthy diet, but was not statistically significant in pain free walking distance and smoking. CONCLUSION: A specialised community based cardiac rehabilitation programme for patients with IC showed statistically and clinically significant effects on maximum walking distance, physical activity, quality of life, and healthy diet, but not on pain free walking distance and smoking, compared with usual care without rehabilitation.

Umbilical Endometriosis Disguised by Seborrheic Keratosis on Punch Biopsy.

ABSTRACT: Endometriosis is a benign condition of the female genital system, characterized by endometrial tissue external to the uterine cavity. Of all cases with endometriosis, the incidence of umbilical endometriosis is only 0.29%. Umbilical endometriosis typical presents with symptoms including cyclical pain, bleeding, and swelling of the nodule. Morphological changes in the epidermis, as in this case, simulating a seborrheic keratosis both clinically and microscopically, can initially mask the underlying endometriosis and prolong the course of treatment. A thorough anamnesis and examination revealing the characteristic symptoms and findings coupled with a representative biopsy is essential to correctly diagnose umbilical endometriosis.

Micro-Lightguide Spectrophotometry (O2C) for Lower Limb Perfusion: Effects of Exercise Walking in Claudicants.

Background Exercise walking has improved walking capacity in patients with intermittent claudication without affecting the macrocirculation reflected in ankle pressures. We wanted to investigate microcirculation in the skin related to exercise walking by using Micro-Lightguide Spectrophotometry (O2C). Materials and Methods Twenty-eight patients with intermittent claudication-bilateral in 17-were included in a 12 weeks of structured home-based exercise program. The pain-free and maximal walking distances were determined on a treadmill. Saturation and flow, monitored by O2C, were examined immediately before and after the treadmill test. O2C examination took place before as well as after completion of the exercise program. Ankle-brachial index was obtained before treadmill testing. Results As expected, walking performance improved significantly without affecting ankle pressures. Neither oxygen saturation nor flow, assessed at 2 mm depth, was affected following a 12 weeks of exercise program. We observed a significant decrease in oxygen saturation and flow upon treadmill testing in the both limbs in patients with bilateral peripheral arterial disease (PAD). In contrast, the treadmill test elicited no changes in the opposite and asymptomatic limb in patients with only unilateral PAD. Conclusion The findings suggest that O2C may be used to study microcirculatory changes. However, it is best suited for the study of phenomena resulting in major changes as it eliminates some inherent variability.
