About 30% of lumbar punctures are complicated by the lumbar puncture syndrome the main symptom of which is a characteristically posture-dependent headache (the so-called "spinal headache"), sometimes accompanied by nausea, vomiting and stiff neck. The syndrome usually begins in the days which follow lumbar puncture and subsides within 10 days. ⋯ The epidural blood patch technique is seldom used. Prevention relies entirely on the use of small calibre lumbar puncture needles; keeping the patient lying supine after the puncture is a classical recommendation, but its preventive value has not yet been fully demonstrated.

Risk factors were analyzed in a group of 117 blood donors seropositive for hepatitis C virus antibody. One risk factor, at least, was found in 63 (53.8%) subjects. ⋯ Our study emphasizes the high percutaneous transmission of hepatitis C in contrast with the low sexual transmission. No risk factor could be found in 54 (46.2%) of the 117 seropositive subjects: the route of transmission in these cases is an intriguing issue which certainly deserves further epidemiological investigations.

Pleuro-pulmonary manifestations are frequent in systemic lupus erythematosus (SLE), being found in 40 to 70% of patients with this disease. However, these manifestations can be attributed to SLE only when other pathologies, and notably infections, have been excluded. The truly SLE-related pleuro-pulmonary manifestations can be divided into five types: pleurisy, interstitial pneumonia, lupus pneumonia and two new entities: diffuse pulmonary haemorrhage and pulmonary arterial hypertension. ⋯ Pulmonary arterial hypertension is a classical, but hitherto unrecognized manifestation of SLE which benefits from new exploratory techniques, such as doppler-ultrasonography. At present, its diagnosis rests on data supplied by cardiac catheterization which is generally performed too late, making it irreversible and resistant to all treatments. Some of these pleuro-pulmonary manifestations are probably underestimated and they require new methods of investigation, such as bronchoalveolar lavage or doppler-ultrasonography, resulting in earlier diagnosis and treatment at an accessible stage.

Hypodermoclysis consists of infusing solutions in the subcutaneous tissues. It is a convenient means of correcting a moderate dehydration, notably in elderly people, when oral feeding is impossible or insufficient. The only potential problem with this technique is the occurrence of hypovolaemia due to infusion of hypo- or hypertonic solutions in subjects with previous severe salt and water disorders. For this reason, hypodermoclysis should not be used in emergencies.
