[Osteoid osteoma of the lower end of the femur--a diagnostic problem].

Joint symptoms may be the first manifestations of juxta-articular osteoid osteoma; therefore, diagnosis may be difficult. We report the case of a young athlete who presented an osteoid osteoma of the distal part of the femur. Correct diagnosis was delayed by the presence of a pathological mid-patellar plica synovialis and the absence of modifications on standard X-rays.

[Sclerosis of the anterior arch of the atlas. A rare congenital abnormality].

The authors report the case of a young man with isolated radiological sclerosis of the anterior arch of the atlas, probably of dysplastic origin. The differential diagnosis of this aspect is discussed.

Irritant principles of the spurge family (Euphorbiaceae). XIII. Oligocyclic and macrocyclic diterpene esters from latices of some Euphorbia species utilized as source plants of honey.

The latices of the three South African species Euphorbia ledienii, Euphorbia coerulescens, and Euphorbia triangularis, belonging to a group of cactiform Euphorbias locally called "Noors," were shown to contain four 12-mono- and three 13,20-diesters of the tetracyclic tigliane type parent alcohol 12-deoxyphorbol [1]. In addition, two 13,16-di- and two 13,16,20-triesters of the related 12-deoxy-16-hydroxyphorbol [9] were obtained. Ester groups in 1 and 9 are made up of acetic, isobutyric, tiglic, angelic, and 2-methylbutyric acid; their positions in the parent alcohols were identified.

[Contribution to the study of the treatment of osteoporosis using fluoride. Long-term sequelae following discontinuation of fluoride].

Eight idiopathic or postmenopausal osteoporotic patients were studied prospectively over a 4- to 6-year period of treatment with fluoride, calcium, phosphate and vitamin D. After fluoride and phosphate were discontinued they were followed up for a further 6-year period.

[Subjective verbal methods in preoperative measurement of anxiety].

The role of preoperative anxiety in perioperative adaptation is viewed in two different ways. Janis suggested that anxiety is a drive that evokes the cognitive work of worrying. Leventhal stresses the importance of coping behavior for adaptation, while anxiety may or may not accompany this coping process.

Measures of memory and information processing in elderly volunteers.

A screening study was carried out in normal elderly volunteers to determine 1. their scores in measures of memory and information processing 2. how the measures correlate with sample characteristics 3.

Origin of cochlea efferents in some gerbil species. A comparative anatomical study with fluorescent tracers.

The distribution and the projection patterns of olivo-cochlear neurons (OCN) was studied in three species of gerbils (Meriones unguiculatus, Meriones tristrami, Pachyuromys duprasi) using fluorescent tracers (Fast blue, Diamidino yellow) in double labeling experiments. In all gerbil species up to 1600 retrogradely labeled neurons were found in the superior olivary complex. Small OCN were located inside or at the margins of the lateral superior olive.

Anterograde and retrograde amnesia after lormetazepam and flunitrazepam.

In a pharmacopsychological study, memory impairments after single oral doses of benzodiazepines or placebo were investigated in 40 healthy men aged 20-40 years. The study was designed as a double-blind and placebo-controlled trial. Four independent groups of 10 subjects randomly received either 1 mg lormetazepam, 2 mg lormetazepam, 2 mg flunitrazepam, or placebo.

Continuous monitoring of mixed venous oxygen saturation during aortic surgery.

The correlation between mixed venous oxygen saturation (SvO2) and hemodynamic measurements was studied in 13 patients undergoing descending thoracic aortic aneurysm resection (DTAAR). A significant correlation (p less than 0.05) was found between cardiac index (CI) and SvO2 after the induction of anesthesia and at the end of surgery.

Alpha ganglion cells in mammalian retinae.

Retinae from species of six orders of mammals (table 1) were processed by an on-the-slide neurofibrillar staining method to establish whether alpha-type ganglion cells are generally present in placental mammals. Alpha cells of the domestic cat, where they were first defined as a type, are used as a standard of reference. Alpha cells were found in all the twenty species examined; characteristically they have the largest somata and large dendritic fields with a typical branching pattern.

Adult septic arthritis with Hemophilus influenzae.

Two cases of Hemophilus influenzae septic arthritis are reported, one in a rheumatoid patient and the other in a healthy young woman after meningitis. The evolution of this rare infectious arthritis was not as good as usual in spite of early therapy. The first patient later presented a Staphylococcus albus bacteriemia and the other a post-infectious persisting arthritis.

Septic manubriosternal arthritis in a patient with Reiter's disease.

A man with a quiescent Reiter's disease presented with abrupt upper chest pain. This symptom resulted from a septic arthritis of the manubriosternal joint due to staphylococcus aureus cultured from the synovial fluid.

[Endoscopic study of digestive lesions caused by the use of nonsteroidal anti-inflammatory agents in rheumatic patients].

44 patients treated with NSAID for a period of over 2 months for a rheumatic disease underwent fibroscopic endoscopy of the upper gastrointestinal tract. Gastric lesions were found to be more frequent than those of the esophagus or duodenum. They occur in men in particular and are not correlated with symptoms or clinical findings.
