Third degree atrioventricular block is considered present when none of the atrial impulses are conducted to the ventricles because of a disruption in the conducting system. Third degree atrioventricular block is usually considered a serious sign but most studies have been performed on hospitalized patients or certain professional groups. The objective of this study was to find the prevalence of third degree atrioventricular block in a representative population sample and estimate its prognostic significance. ⋯ The prevalence of third degree atrioventricular block in this general population was low but nevertheless considerably higher than previously reported. The block was temporary in the majority of subjects. All had some underlying heart disease which seemed to affect the prognosis more than the heart block. In this survey fewer subjects than expected were found to need a pacemaker.

The Health Centre at Kirkjubaejarklaustur serves a large rural district with a population a little over 600. Agriculture and various services including tourism are the main occupations. Almost 20% of the population are over 65 years of age, which is an unusually high figure compared to the rest of the country. Ambulance transports are one of the health centre's responsibilities. Most of these are surface transports to hospitals, 200-250 kilometres away. ⋯ Ambulance transport including the preparation of the sick or injured person is an important part of health care in this region. General practitioners need to be well versed in emergency medicine and ambulance attendants in preparing the patient for transport. Therefore continuing education is an important factor in this discussion. Tourism in the summertime may prompt the need for increased staffing in the health care sector. There is no indication that helicopter transport will replace surface transport in the near future except in special cases as it has been. Good primary health care and regular access to physicians in the nursing home setting decrease the need for ambulance transport. Further studies in the area of ambulance transport especially concerning tourists and the elderly are needed in the Icelandic context. Both groups are on increase and will probably be more in demand of emergency medical services such as ambulance transports.

Ultrasonography detection of radiolucent foreign bodies in soft tissue compared to computed tomography scan.
Thirty-one patients with suspected radiolucent foreign bodies (wooden splinters) in soft tissues of extremities were investigated by plain radiography, computed tomography (CT) scan and ultrasonography to the area suspected clinically. Ultrasonography detected and localized radiolucent foreign bodies in 18 of the 31 patients, while only 14 were seen on CT scan. ⋯ The size of foreign body, the presence of infection or the delay in diagnosis had no effect on results. Ultrasonography is clearly a reliable method of detecting radiolucent foreign bodies in soft tissues of extremities.

Helicobacter pylori infection in gastric cancer: A study of 84 cases from Asir Region.
Gastric cancer can be divided into three histologic types: intestinal and diffuse adenocarcinoma, and malignant lymphoma. To determine whether Helicobacter pylori was associated with either cancer type, we reviewed histologic sections from stomachs of 84 patients with the diagnosis of gastric. Of 63 patients with histologic evidence of intestinal adenocarcinoma, 53 (84%) contained H. pylori n noncancerous tissue compared with six (66.7%) of nine patients with diffuse adenocarcinoma (odds ratio = 2.65; Z=1.048; P>0.05) and with eight (66.7%) of 12 patients with non-Hodgkin malignant lymphoma of the stomach (odds ratio = 2.65; Z=0.826; P>0.05). Our findings are compared with reported data from other countries and we are not aware of similar reports from the Kingdom of Saudi Arabia.

In addition to the acute adverse consequencesof ectopic pregnancy, the subsequent reproductive potential of the affected women has continued to attract the attention of medical scientists in recent times. In a study to evaluate the fertility potentials in 138 patients treated for ectopic pregnancy in the King Khalid University Hospital (KKUH) Riyadh, 105 (76.1%) of the patients had follow-up management for periods varying from 12 to 60 months. ⋯ Of these, 51 (48.6%) eventually became pregnant and produced 63 viable pregnancies, 18 abortions and one repeat ectopic pregnancy. Many of those who failed to become pregnant over the follow-up period probably had tubal damage due to the antecedent pelvic inflammatory disease (PID),perhaps compounded by the effects of the ectopic pregnancy and the management, among other factors.
