ABSTRACT
BACKGROUND: Pulsed dye laser (PDL) treatment is widely used for poikiloderma of Civatte. Some adverse events in small numbers of patients have been reported. Guidelines for treatment of poikiloderma of Civatte do not exist. OBJECTIVE: To report the occurrence of persistent depigmentation as a late adverse event in a series of patients with poikiloderma of Civatte after treatment with PDL. METHODS: Eight patients (seven women and one man, mean age 48 years) with poikiloderma of Civatte were treated with PDL using a 585-nm wavelength and a fixed pulse duration of 450 micros. In all patients one or two test PDL patches were performed and reviewed after 3 months. All of the patients tolerated the testing without complications. Subsequent treatments were undertaken at intervals of 3 months. RESULTS: All patients were treated with fluences between 3.5 and 7 J/cm2, using a 7- or 10-mm spot size. All patients had a good result with respect to clearing of the vascular component. Nevertheless, six of them, treated with 5-7 J/cm2, reported severe depigmentation 4-11 months after treatment. Two patients treated with lower fluences (3.5-5.5 J/cm2) did not report this depigmentation. CONCLUSIONS: Great care is needed when PDL treatment is used for poikiloderma of Civatte. Pigment changes have been incidentally mentioned as late complications but have not been well documented as the late depigmentation has been in this series. It is advisable to use fluences as low as possible, and not exceeding an upper limit of 5 J/cm2, on a 10-mm spot size. More research is needed to define an optimal pulse duration.

Two men, aged 52 and 57 years, had vomited and then developed chest pain, dyspnoea and tachypnoea. After a myocardial infarction had been excluded in the cardiac emergency room, further examination revealed a rupture of the oesophagus. This was treated surgically with the ultimate creation of a tubular stomach. Both patients then recovered well. The Boerhaave's syndrome, a 'spontaneous' perforation of the oesophagus, is a rare and potentially lethal condition which should be diagnosed at an early stage. Pain in the chest, dyspnoea and vomiting are frequent symptoms. A cardiac cause is sometimes erroneously suspected. Subcutaneous emphysema is a major indication for a perforation of the oesophagus. The chest X-ray shows also mediastinal emphysema and infiltrative abnormalities; in case of doubt a second X-ray should be made some hours later.
