Long-Term Survival and Quality of Life After Hypothermic Circulatory Arrest in Aortic Surgery.

BACKGROUND AND AIMS:: Hypothermic circulatory arrest carries a high risk of mortality and neurological complications. An important part of assessing surgical treatment is the evaluation of long-term survival and postoperative health-related quality of life. MATERIAL AND METHODS:: In this prospective study, 30 patients undergoing hypothermic circulatory arrest during surgery of the thoracic aorta, and 31 comparison patients undergoing elective coronary artery surgery without hypothermic circulatory arrest were evaluated for long-term survival and health-related quality of life, using the RAND 36-Item Health Survey questionnaire. The results were compared to national age- and sex-matched reference populations of the chronically ill and healthy adults. RESULTS:: After 4.6-8.0 years, available study (88%) and comparison (59%) patients were interviewed. The life expectancy was similar with 4- and 8-year survival of 90%, and 87% for the study group, and 94%, and 94% for the comparison group, respectively (log rank test, p = 0.62). The RAND-36 scores for study and comparison groups were congruent in all dimensions, describing physical, mental, and social domains. The study patients' health-related quality of life results were similar to the national reference population with chronic illnesses. CONCLUSION:: After hypothermic circulatory arrest, patients undergoing surgery of the thoracic aorta achieve a similar long-term life expectancy and health-related quality of life as do patients undergoing coronary surgery without hypothermic circulatory arrest, and a health-related quality of life similar to the national reference population with chronic illnesses. These results justify operative treatment in this high-risk patient population.

Efficacy of topical resin lacquer, amorolfine and oral terbinafine for treating toenail onychomycosis: a prospective, randomized, controlled, investigator-blinded, parallel-group clinical trial.

BACKGROUND: Norway spruce (Picea abies) produces resin to protect against decomposition by microbial pathogens. In vitro tests have shown that spruce resin has antifungal properties against dermatophytes known to cause nearly 90% of onychomycosis in humans. OBJECTIVES: To confirm previous in vivo observations that a topical resin lacquer provides mycological and clinical efficacy, and to compare this lacquer with topical amorolfine hydrochloride lacquer and systemic terbinafine for treating dermatophyte toenail onychomycosis. METHODS: In this prospective, randomized, controlled, investigator-blinded study, 73 patients with onychomycosis were randomized to receive topical 30% resin lacquer once daily for 9 months, topical 5% amorolfine lacquer once weekly for 9 months, or 250 mg oral terbinafine once daily for 3 months. The primary outcome measure was complete mycological cure at 10 months. Secondary outcomes were clinical efficacy, cost-effectiveness and patient compliance. RESULTS: At 10 months, complete mycological cure rates with the resin, amorolfine and terbinafine treatments were 13% [95% confidence interval (CI) 0-28], 8% (95% CI 0-19) and 56% (95% CI 35-77), respectively (P ≤ 0·002). At 10 months, clinical responses were complete in four patients (16%) treated with terbinafine, and partial in seven (30%), seven (28%) and nine (36%) patients treated with resin, amorolfine and terbinafine, respectively (P < 0·05). Resin, amorolfine and terbinafine treatments cost €41·6, €56·3 and €52·1, respectively, per patient (P < 0·001). CONCLUSIONS: Topical 30% resin lacquer and topical 5% amorolfine lacquer provided similar efficacy for treating dermatophyte toenail onychomycosis. However, orally administered terbinafine was significantly more effective in terms of mycological cure and clinical outcome than either topical therapy at the 10-month follow-up.

Local dressings for pressure ulcers: what is the best tool to apply in primary and second care?

A vast range of dressings can be used on pressure ulcers, but despite this and the high expense often involved, there is no gold standard for the local treatment of these wounds. This literature review therefore set out to examine the evidence.

Beneficial effect of resin salve in treatment of severe pressure ulcers: a prospective, randomized and controlled multicentre trial.

BACKGROUND: Resin salve of the Norway spruce (Picea abies) has been used in folk medicine to heal wounds and infections. OBJECTIVES: To study its clinical effectiveness in the treatment of pressure ulcers of the skin. METHODS: A prospective, randomized, controlled multicentre trial involving 37 patients with grade II-IV pressure ulcers in 11 primary care hospitals was carried out between 2005 and 2007. The ulcers were randomly allocated to receive either resin salve or sodium carboxymethylcellulose hydrocolloid polymer treatment. The inclusion criterion was grade II-IV pressure ulcer. Exclusion criteria were a life expectancy of less than 6 months or a malignant disease. The primary outcome measure was complete healing of the ulcer within 6 months. Secondary outcome measures were partial healing of the ulcer, and successful eradication of bacterial strains cultured from the ulcers at study entry. RESULTS: Thirteen patients of the resin group and nine patients of the control group completed the 6-month trial. All ulcers healed in 12 of the 13 patients (92%) in the resin group and in four of the nine patients (44%) in the control group (P=0.003; power 73%). Complete healing of the ulcers over time was significantly more common in the resin group than in the control group (P=0.013). Bacterial cultures from the ulcer area more often became negative within 1 month in the resin group. CONCLUSIONS: Traditional resin salve is significantly more effective in the treatment of infected and noninfected severe pressure ulcers than cellulose polymer gauzes.

Antibacterial effects of home-made resin salve from Norway spruce (Picea abies).

Resin salve made from Norway spruce (Picea abies) is traditionally used in folk medicine to heal skin ulcers and infected wounds. Its antimicrobial properties were studied against certain human bacteria important in infected skin wounds. The sensitivity of the resin against Gram-positive and Gram-negative bacteria was studied in vitro by methods that are routinely used in microbiology laboratories. The resin salve exhibited a bacteriostatic effect against all tested Gram-positive bacteria but only against Proteus vulgaris of the Gram-negative bacteria. Interestingly, the resin inhibited the growth of bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE), both on agar plates and in culture media. The study demonstrated antimicrobial activity of the resin salve and provided objective evidence of its antimicrobial properties. It gives some explanations why the traditional use of home-made resin salve from Norway spruce is experienced as being effective in the treatment of infected skin ulcers.

Results and future of carotid endarterectomy in a medium-sized Finnish central hospital.

BACKGROUND AND AIMS: Carotid endarterectomies (CEA) should, by general agreement, be performed only at specialised institutions and on patients who are expected to have a low rate of complications, i.e., a 6% surgical risk for patients with symptomatic and a 3% risk for patients with asymptomatic carotid artery disease. We have reviewed the midterm results after CEA in a medium-sized Finnish central hospital to audit whether our results fulfil current quality standards. PATIENTS, MATERIALS AND METHODS: There were 116 consecutively operated patients at the Päijät-Häme Central Hospital during the years 1999-2003 on whom 122 CEAs were made. All CEAs were performed by conventional methods and shunts and patches were used when necessary. RESULTS: The overall survival rate was 81.0% during the 3.6 +/- 1.5 years [range 1.3-6.3 years] follow-up. The incidence of early major stroke was 2.5% and of late major stroke 1.6%. Other complications included cranial nerve deficit (2.5%), wound haematoma (3.3%) and postoperative hypertension (3.3%) or hypotension (2.5%). Significant changes in medication were needed after surgery in several patient subgroups. CONCLUSIONS: The results of CEA at the Päijät-Häme Central Hospital are at least acceptable. The primary prevention of strokes with pharmacotherapy needs aggressive improvement.
