- Interviews were carried out with 423 women and 93 men with invasive or in situ anal cancer in Denmark and Sweden in a search for clues to the aetiology of this neoplasm. Patients with rectal adenocarcinoma (n = 534) and persons drawn from the background population (n = 554) served as controls. Multivariate logistic regression analyses confirmed previous observations of a strong association between either male homosexual experience or a history of anogenital warts and the risk for anal cancer. Moreover, hitherto unknown, but strong and consistent associations were observed between measures of high heterosexual activity and the risk for anal cancer among both sexes. Polymerase chain reaction analysis revealed human papilloma-virus DNA in the majority (88%) of anal cancer specimens but in none of 20 examined rectal adenocarcinomas. It is concluded that most anal cancers appear to be caused by sexually transmitted types of human papillomaviruses and, consequently, that anal cancer is a potentially preventable neoplasm.

- Eighty patients with monoradicular sciatica were examined by myelography, computed tomography (CT) and magnetic resonance imaging (MRI) and all had subsequent surgery. The images were evaluated by a decision-analytic regret function. The largest amount of diagnostic information was gained from CT followed by MRI and myelography. Myelography was not significantly informative. The results suggest that CT or MRI should be the first choice examination in patients with suspected lumbar disc herniation.

- Acute acalculous cholecystitis (AC) is an inflammatory process of the gallbladder, often caused by other severe diseases. The etiology is multifactorial, but the pathogenesis is in all cases a reduction in the gallbladder's emptying capacity. The mortality of AC reaches 85% without treatment. This fact makes it important to consider AC as a possible complication to major surgery, multi-trauma, and artificial ventilation. Symptoms resemble "normal" cholecystitis, but may be masked by the underlying severe disease. Fever without known focus may be the only symptom. Ultrasound, CT-scanning or cholangiography are used to verify the diagnosis, supplemented by laboratory investigations. Treatment is cholecystectomy. Percutaneous ultrasonic guided cholecystotomy is a good alternative if the diagnosis made in an early stage. The mortality is considerably reduced by early intervention.

Tuberkuloseudviklingen i Danmark 1972-1996

- The present study is based on notified cases of tuberculosis (TB) in the National tbc. register 1972-1996. A decline in Tb incidence was seen from 1972 and until the mid-1980's. Subsequently the trend has reversed due to an increasing number of TB cases in foreigners. In 1996, 60% of all cases of TB in Denmark were found in foreigners reflecting the rising number of refugees and their families arriving in Denmark from highly endemic areas, mainly Somalia. Among native Danes the TB incidence fell from 14 per 100,000 in 1972 to 4 per 100,000 in the 1980's and stabilized at this very low level. The unchanged incidence in Danes covers a falling incidence in the older and a rising incidence in the younger and middle-aged adult population, mainly in the capital. Approximately half of the cases occur in high-risk groups. The TB-epidemic is close to elimination in the indigenous Danish population, but the disease is maintained at a low level probably due to increased patient and doctor delay and resulting microepidemics primarily in high-risk populations.

- At present, when economy and environment receive high priority, the ideal anaesthesia system with inhalation anaesthetics is a closed circle system in which only the gases which the patient consumes or produces are replaced or eliminated. Low-flow (LF) anaesthesia in which the fresh gas flow which is employed in a closed system, provides a stable system compares with closed anaesthesia systems. Compared with open systems and circler systems with considerable fresh gas flow, the LF system provides advantages as regards economy, environment and exposure of staff to inhalation anaesthetics. The special conditions involved in LF anaesthesia are described in detail with the hope that the method will obtain more widespread distribution than is the case in Denmark today. If greater safety under anaesthesia is desired, eg by monitoring the concentrations of CO2, O2 and inhalation anaesthetics which the patients inspire and expire, this monitoring equipment can be financed by introduction of LF anaesthesia.
