- BACKGROUND AND AIMS: In critically ill patients, cholecystectomy is associated with a high mortality rate. The aim of this study was to evaluate the safety, efficacy and long-term outcome of ultrasound-guided percutaneous cholecystostomy (USGPC) in critically ill patients with acute cholecystitis.MATERIALS AND METHODS: Clinical records of 51 patients, all considered high-risk surgical patients, with acute cholecystitis treated with USGPC between 1987 and 1999, were retrospectively reviewed. Response was defined as improvement in clinical symptoms and signs, and/or reduction in c-reactive protein and white blood count levels within 72 h. Long-term results were evaluated by means of clinical records and written correspondence.RESULTS: Gallbladder stones were seen in 28 patients whereas 23 had acalculous cholecystitis. Ninety percent showed clinical improvement after USGPC. Cholecystectomy was performed in 16%, of which 6% after recurrent cholecystitis. Recurrence of cholecystitis occurred in 22%. Hospital mortality was 16%. None of the deaths was procedure related or related to acute cholecystitis alone. Major complications relating to the USGPC were rare (4%), while minor catheter-related complications were quite common.CONCLUSIONS: USGPC is a procedure with few complications and a high success rate. In patients with acalculous cholecystitis as well as in many patients with calculous cholecystitis, no further treatment was needed.

- Identification of host volatile compounds attractive to codling moth Cydia pomonella, a most important insect of apple, will contribute to the development of safe control techniques. Synthetic apple volatiles in two doses were tested for antennal and behavioural activity in codling moth. Female antennae strongly responded to (Z)3-hexenol, (Z)3-hexenyl benzoate, (Z)3-hexenyl hexanoate, (+/-)-linalool and E,E-alpha-farnesene. Two other compounds eliciting a strong antennal response were the pear ester, ethyl (E,Z)-2,4-decadienoate, and its corresponding aldehyde, E,E-2,4-decadienal, which is a component of the larval defence secretion of the European apple sawfly. Attraction of codling moth to compounds eliciting a strong antennal response was tested in a wind tunnel. Male moths were best attracted to a blend of (E,E)-alpha-farnesene, (E)-beta-farnesene and ethyl (E,Z)-2,4-decadienoate. The aldehyde E,E-2,4-decadienal had an antagonistic effect when added to the above mixture.

- The antennal responses of codling moth females, Cydia pomonella, to volatiles from apple branches with green fruits were recorded by electroantennography coupled to gas chromatography. The antennae strongly responded to 4,8-dimethyl-1,3(E),7-nonatriene, linalool, beta -caryophyllene, (E)-beta -farnesene, germacrene D, (Z,E)-alpha -farnesene, (E,E)-alpha -farnesene and methyl salicylate. These compounds were all present in volatile collections on Porapak Q from both living and cut branches. Analysis by the solid phase microextraction technique (SPME) showed that the emission of some electrophysiologically active compounds increased after branches had been cut, especially 4,8-dimethyl-1,3(E),7-nonatriene, linalool and (E,E)-alpha -farnesene. The identification of apple volatiles eliciting antennal responses is the first step towards the identification of compounds mediating host-finding and oviposition in codling moth females.

- Volatile compounds were collected from apple branches (Malus domestica) at different developmental stages, and the antennal response of codling moth females (Cydia pomonella) to these compounds was recorded by electroantennography coupled to gas chromatography. Presence of a range of terpenoid compounds, many of which had antennal activity, was characteristic for volatile collections from branches with leaves, and from small green apples. Nine compounds from branches with leaves and green fruit consistently elicited an antennal response: methyl salicylate, (E)-beta -farnesene, fi-caryophyllene, 4,8-dimethyl-1,3(E),7-nonatriene, (Z)3-hexenol, (Z,E)-alpha -farnesene, linalool, germacrene D, and (EE)-alpha -farnesene. The bouquet emitted from flowering branches contained in addition several benzenoid compounds which were not found after bloom. Small green apples, which are the main target of codling moth oviposition during the first seasonal flight period, released very few esters. In comparison, fully grown apples released a large number of esters, but fewer terpenoids. The study of apple volatiles eliciting an antennal response, together with a survey of the seasonal change in the release of these compounds, is the first step toward the identification of volatiles mediating host-finding and oviposition in codling moth females.

- The study evaluates the factor structure and predictive validity of the symptom questionnaire EUROQUEST (EQ) that had been developed with the goal of simplifying the evaluation of health effects associated with long-term solvent exposure. The EQ was added to the normal evaluation procedures for 118 male patients with suspected solvent-induced toxic encephalopathy (TE) referred to seven Swedish clinics of occupational medicine during an 18-month period. EQ was also completed by 239 males from a random sample of 400 Swedish males aged 25-64 years selected from the general population and a sample of 559 occupationally active male spray painters aged 25-64 years. Factor and item analyses of EQ responses were performed. Ordinary least square regression analysis was used to evaluate sensitivity and correlation to evaluate the specificity of EQ and the separate components. Questions concerning memory and concentration symptoms alone showed better sensitivity than the other five EQ dimensions singly or combined for the entire EQ and for a subset of questions approximating Q16, a widely used organic solvent symptom screening questionnaire. However, the diagnosis of TE required information in addition to exposure and responses to EQ and Q16-like questions. The results indicate that the subset of EQ questions concerning memory and concentration might replace the more cumbersome EQ and less sensitive Q16 in screening for TE, although none of the screening instruments alone replaces current clinical diagnostic procedures.

- AIM: To describe the epidemiology for out of hospital cardiac arrest of a non-cardiac aetiology. PATIENTS: All patients suffering from out of hospital cardiac arrest in whom resuscitation efforts were attempted in the community of Göteborg between 1981 and 2000. METHODS: Between October 1, 1980 and October 1, 2000, all consecutive cases of cardiac arrest in which the emergency medical service (EMS) system responded and attempted resuscitation were reported and followed up to discharge from hospital. RESULTS: In all, 5415 patients participated in the evaluation. Among them 1360 arrests (25%) were judged to be of a non-cardiac aetiology. Among these 24% were caused by a surgical cause or accident, 20% by obstructive pulmonary disease, 13% by drug abuse and the remaining 43% by 'another cause'. Of the patients with out of hospital cardiac arrest of a non-cardiac aetiology 4.0% survived to discharge from hospital as compared with 10.1% of the patients with a cardiac aetiology (P<0.0001). In the various subgroups survival was highest in those with drug abuse (6.8%) and lowest in those with 'another cause' (4.2%). Cerebral performance categories (CPC) score at hospital discharge tended to be worse among survivors from an arrest of non-cardiac than cardiac aetiology. Patients with a cardiac arrest of a non-cardiac aetiology differed from the remaining patients by being younger, including more women, less frequently having a witnessed arrest and less frequently being found in ventricular fibrillation/tachycardia. When simultaneously considering age, sex, witnessed status, presence of bystander cardiopulmonary resuscitation (CPR) and initial arrhythmia, the aetiology (non-cardiac vs. cardiac aetiology) was not an independent predictor of survival. CONCLUSION: Among patients with out of hospital cardiac arrest in whom resuscitation was attempted 25% were judged to be of a non-cardiac aetiology. These patients had a lower survival than patients with a cardiac arrest of cardiac aetiology. However, this was mainly explained by a lower occurrence of ventricular fibrillation and witnessed cardiac arrest.
