Treatment in a specialised mood disorder clinic early in the course of bipolar disorder substantially reduces readmission to a psychiatric hospital and increases satisfaction with care.

The minor risk of ST and MI within 15 months after implantation of DES seems unlikely to outweigh the benefit of these stents.

Objectives: To investigate the frequency, circumstances, and causes of occupational accidents aboard merchant ships in international trade, and to identify risk factors for the occurrence of occupational accidents as well as dangerous working situations where possible preventive measures may be initiated. Methods: The study is a historical follow up on occupational accidents among crew aboard Danish merchant ships in the period 1993-7. Data were extracted from the Danish Maritime Authority and insurance data. Exact data on time at risk were available. Results: A total of 1993 accidents were identified during a total of 31 140 years at sea. Among these, 209 accidents resulted in permanent disability of 5% or more, and 27 were fatal. The mean risk of having an occupational accident was 6.4/100 years at sea and the risk of an accident causing a permanent disability of 5% or more was 0.67/100 years aboard. Relative risks for notified accidents and accidents causing permanent disability of 5% or more were calculated in a multivariate analysis including ship type, occupation, age, time on board, change of ship since last employment period, and nationality. Foreigners had a considerably lower recorded rate of accidents than Danish citizens. Age was a major risk factor for accidents causing permanent disability. Change of ship and the first period aboard a particular ship were identified as risk factors. Walking from one place to another aboard the ship caused serious accidents. The most serious accidents happened on deck. Conclusions: It was possible to clearly identify work situations and specific risk factors for accidents aboard merchant ships. Most accidents happened while performing daily routine duties. Preventive measures should focus on workplace instructions for all important functions aboard and also on the prevention of accidents caused by walking around aboard the ship.

The routine use of distal protection by a filterwire system during primary PCI does not seem to improve microvascular perfusion, limit infarct size, or reduce the occurrence of MACCE.

Objective-To describe and analyse the types and circumstances of all natural and non-natural deaths among seamen on board Danish merchant ships. Methods-Data on 147 cases were obtained from maritime authorities, an insurance company, shipping companies, hospitals, death registers, and death certificates in the period from 1986-93. Results-The 53 natural deaths were dominated by cardiovascular diseases and infectious diseases. Insufficient treatment on board was identified as a contributing factor for death in some cases. Medical advice was not always sought and the advice given was in some cases insufficient. 73 fatal accidents were identified.The incidence of accidents of 5.29110 000 person-years was 11-5 times higher than the incidence of 0-46/10 000 for the Danish male workforce ashore. 23 accidents (31%) were due to maritime casualties and 26 (36%) were occupational accidents. The remaining 24 (33%) were accidents during off duty hours including six self intoxications. Rough weather, inadequate awareness of safety, lack of use of personal protection devices, and inexperience were associated with many of the fatal injuries directly related to work. Alcohol played a major part in 12 out of 18 fatal injuries occurring during off duty hours. Conclusions-The maritime workplace was identified as a high risk workplace and in many aspects differs from the conditions ashore. Acute diseases and serious injuries pose special risks to seamen because of a lack of direct access to professional medical care at sea. Primary prevention of certain diseases is needed and possible. Improved training, improved systems of work, improved safety awareness, and greater use of personal protection devices are needed to prevent fatal injuries. Medical training of ships' officers providing medical care on board and specific training of doctors giving medical advise to ships should be improved to meet the needs.

Several noninvasive studies have shown the effect on heart failure of treatment with coenzyme Q10. In order to confirm this by invasive methods we studied 22 patients with mean left ventricular (LV) ejection fraction 26%, mean LV internal diameter 71 mm and in NYHA class 2-3. The patients received coenzyme Q10 100 mg twice daily or placebo for 12 weeks in a randomized double-blinded placebo controlled investigation. Before and after the treatment period, a right heart catheterisation was done including a 3 minute exercise test. The stroke index at rest and work improved significantly, the pulmonary artery pressure at rest and work decreased (significantly at rest), and the pulmonary capillary wedge pressure at rest and work decreased (significantly at 1 min work). These results suggest improvement in LV performance. Patients with congestive heart failure may thus benefit from adjunctive treatment with coenzyme Q10.

Lack of knowledge about affective disorder and its treatment and a critical attitude, especially among older patients, may add to an adverse prognosis of depressive and bipolar disorders.

Aims: To study morbidity among active seafarers in the merchant navy in order to clarify possible work related morbidity and the morbidity related to work and lifestyle where possible preventive measures may be initiated. Methods: From a register in the Danish Maritime Authority a cohort of Danish merchant seafarers who had been actively employed at sea in 1995 was identified. For each seafarer, information on all employment periods at sea, charge aboard, and ship was available. The cohort was linked with the National In-patient Register in Denmark. Standardised hospitalisation ratios (SHRs) were calculated for all major diagnostic groups using all gainfully employed as reference. Results: Seafarers were shown to be inhomogeneous, with significant differences in SHRs for the same disease groups between different groups of seafarers depending on charge and ship type. SHRs for lifestyle related diseases were high, although rates for acute conditions, such as acute myocardial infarction, were low, probably due to referral bias, as acute conditions are likely to cause hospitalisation abroad, and thus are not included in the study. SHRs for injury and poisoning were high, especially for ratings and officers aboard small ships. Conclusion: Despite pre-employment selection, a large proportion of the seafarers constitute a group of workers with evidence of poor health probably caused by lifestyle. The subgroups with high risk of hospitalisation due to lifestyle related diseases also had an increased risk of hospitalisation due to injury and poisoning.
