Intracoronary shunt reduces postoperative troponin leaks: a prospective randomized study.

OBJECTIVE: The purpose of this study was to evaluate whether intracoronary shunt usage reduced the myocardial damage on the basis of the cardiac markers when compared with the shuntless anastomosis in off-pump coronary artery bypass grafting (OPCABG) surgery of isolated left anterior descending artery lesions. METHODS: Forty patients who had stable angina with isolated left anterior descending (LAD) coronary artery lesion undergoing OPCABG surgery were randomized into two groups. Shunt group consisted of 20 patients who had OPCABG using intracoronary shunt, whereas the shuntless group consisted of 20 patients who underwent OPCABG without using intracoronary shunt. Cardiac troponin I, CK, and CK-MB before and 24h after the surgery were assessed in the groups. RESULTS: There were no deaths in the study. The two groups were similar with respect to sex and age. Duration of LIMA-LAD anastomosis was significantly higher in the shunt group (p=0.01). There was no significant difference between the groups concerning the preoperative and postoperative CK and CK-MB levels. The preoperative troponin I levels of the groups were not different (p=0.238; NS), whereas postoperative levels of this marker was significantly higher in the shuntless group (p=0.003). CONCLUSION: Intracoronary shunt reduced the postoperative troponin I levels significantly, so it may be indicated in the patients who are thought to be susceptible to transient ischemia.     

Comparison of completion thyroidectomy and primary surgery for differentiated thyroid carcinoma.

AIM: The objective of this study is to analyze the complication rates after the completion thyroidectomy and compare them with primary total thyroidectomy. METHODS: The outcomes of patients with differentiated thyroid carcinoma who were operated over a period of eight years were evaluated. One hundred and forty-one patients underwent completion thyroidectomy and 92 patients had primary surgery. RESULTS: The two groups were comparable in respect of clinical variables. Residual tumor was found in 66 of 141 patients (46.8%) in completion thyroidectomy group. The rate of the two most important complications, permanent recurrent laryngeal nerve palsy and permanent hypoparathyroidism were 3.5 and 4.2%, in completion thyroidectomy group, and 3.3 and 4.3%, in primary total thyroidectomy group. The complication rates were not significantly different between groups. CONCLUSION: In conclusion, completion thyroidectomy can be done safely in a specialized center with acceptable morbidity.     

Effect of an education and activation programme on functional limitations and patient-perceived recovery in acute and sub-acute shoulder complaints – a randomised clinical trial

Background  

The education and activation programme (EAP) aims at coping with psychosocial determinants to prevent the development of chronic shoulder complaints (SCs). The effect of the EAP on functional limitations and patient-perceived recovery after 6 and 26 weeks is evaluated in a randomised clinical trial.     

Psychological well‐being and psychosocial work environment characteristics among emergency medical and nursing staff

The aim of this study was to determine if the effect of psychosocial work environment on psychological well‐being was different for doctors and nurses who work in emergency departments in Spain. A cross‐sectional survey was carried out among 945 emergency doctors and nurses staff from Spain. The outcome variable was the psychological well‐being measured by two dimensions of SF‐36 Health Survey (SF‐36) (mental health, vitality) and one dimension of Maslach's Burnout Inventory (emotional exhaustion). The explanatory variable was the psychosocial work environment evaluated according to Karasek and Johnson's demand‐control model that includes the dimensions of psychological demands, job control, supervisor social support and co‐workers' social support. The adjusted odds ratios and their 95 per cent confidence intervals were calculated by logistic regression. The prevalence of low vitality, bad mental health and high emotional exhaustion was higher among doctors than nurses. Exposure to high psychological demands increased the probability of low vitality, bad mental health and high emotional exhaustion among doctors and nurses. Low job control and low co‐workers' social support at work were associated with poor psychological well‐being only among doctors. Low job supervisors' social support increased the risk of bad mental health among doctors and of high emotional exhaustion among nurses. There is a different effect of psychosocial work environment on psychological well‐being between doctors and nurses. Copyright © 2007 John Wiley & Sons, Ltd.

Scar endometriosis—a gynaecologic pathology often presented to the general surgeon rather than the gynaecologist: report of two cases

Introduction Scar endometriosis develops in and is adjacent to surgical scars at the site of previous abdominal operations. The most frequent clinical presentation of the disease is that of a palpable subcutaneous mass near surgical scars associated with cyclic pain and swelling during menses. Endometriosis of the surgical scar is often referred to the general surgeons because the clinical presentation suggests an incisional hernia or other conditions related to the general surgery. Cyclical symptoms such as pain and swelling, in relation to surgical scars, which worsen at the time of menstruation, are nearly pathognomonic of scar endometriosis. However, often the diagnosis of endometriosis is not suggested until after histology has been performed. Case report We present two cases of cutaneous endometriosis that has occurred on the site of previous cesarean section scar area.
