Urinary diagnosis of gonorrhoea and Chlamydia in men in remote aboriginal communities.

AIMS: (1) To evaluate the acceptability and validity of an intervention based on urine tests for diagnosis and treatment of gonorrhoea and chlamydia in men in remote Aboriginal communities. (2) To provide a prevalence estimate of these infections in the male population in the surveyed communities. METHODS: First-void urine samples from 460 men in remote communities and 33 men in the Alice Springs Gaol were tested for gonorrhoea and chlamydia with at least one of polymerase chain reaction (PCR), enzyme immunoassay (EIA) and culture (gonorrhoea only). RESULTS: One hundred and three men (20.9%) were infected with gonorrhoea or chlamydia. The prevalence of infection for gonorrhoea only was 11.7%, for chlamydia only 4.1% and for dual infection 5.1%. Eighty-eight infected men and 45 of their sexual partners were recorded as having been treated within two months of testing. PCR tests detected the largest number of infections and were the easiest to use. CONCLUSIONS: The prevalence of these infections was higher than anticipated. Urine PCR tests were acceptable to men and are well suited to the remote-community setting. As an effective alternative to urethral swabs, they permit a range of community-based strategies to address high rates of infection with gonorrhoea and chlamydia.

Prototype system for archiving and transmitting digitized radiographs.

A prototype system for archiving and transmitting digitized dental radiographs is described. The system uses a CCD video camera, IBM compatible personal computer with a frame-grabber and a high resolution VGA monitor. All archived images were compressed lossless by a factor of about 3. Digitized radiographs were archived together with their exposure data and assembled in an examination with a unique identifier and date of examination, together with the patient's history and reason for radiological examination. A radiological report with a list of differential diagnoses could be attached. Each examination could contain 50 digitized radiographs which could be converted to a tagged image file (TIFF) and printed halftone with a laser printer. Users of the system could receive examinations from the network-server and share the images in a local area network.

[A comparison of two methods for pre-operative radiographic examination in treatment with oral implants in the anterior mandibular area].

Insertion of osseointegrated implants in the anterior mandibular region for retaining a removable denture represents a treatment, which is cheap for the patient and surgically uncomplicated. Bone height measures from two radiographic examinations 1) panoramic radiographs and 2) lateral tangential views, were compared. Radiographs from 20 patients were analyzed. The vertical height of the mandible was measured in the midline as well as in the cuspid region on the panoramic radiographs and the tangential views ("maximum" bone heights). The mean maximum bone heights were higher on tangential views in both regions. On the tangential views the inclinations of the future implants were estimated and the part of the alveolar ridge having a width less than 5 mm, which is the minimum width for housing an implant, was compiled. The resulting height ("effective bone height") was calculated. In 10% of the cases the effective bone height was equal to the maximum height, and in 90% it was smaller. The over-estimation varied between 0 mm and 15.3 mm. It is concluded that panoramic radiographs are unreliable for evaluating bone height in planning insertion of oral implants in the anterior mandibular region. They give no information about form and width of the bone. Tangential views reveal the true morphology of the mandible as seen in a cross-section, and offer an opportunity for calculating the effective bone height at disposal for oral implants.
